Each explanation must be non-empty, specific to that variable, and concise. Each explanation must support the numeric value submitted for the same variable in `answers`. If an explanation mentions a final amount, that amount must match the corresponding `answers` value. Do not write that you will use one value while submitting a different value. Put only numeric values in `answers`, with no dollar signs, commas, or explanatory text in the values. Do not rely on plain text outside the JSON object for the final answers. If an answer is a currency amount, give the annual amount. If an answer is a rate, give a decimal (e.g. 0.25 for 25%)."}}}, "modelStats": [{"model": "gpt-5.5", "condition": "no_tools", "score": 90.02658431793769, "exact": 86.6186895810956, "within1pct":

SNAP has a vehicle asset test; in Pennsylvania, vehicles above a certain value count toward the asset limit. However, the more fundamental issue is that with zero listed income, the household would appear income-eligible, but with no listed expenses for rent or utilities and only one person, the net monthly income after deductions would be near zero, potentially generating a small benefit. However, the vehicle value of $37,600 is relevant: Pennsylvania uses the broad-based categorical eligibility (BBCE) for SNAP, which typically eliminates the asset test for most households. Under BBCE in PA, there is no vehicle asset test. With $0 gross income, the household of 1 would have a net income of $0 after the standard deduction (~$204/month in 2026 for 1 person), but net income cannot go below $0. The maximum SNAP benefit for a 1-person household in 2026 is approximately $292/month ($3,504/year). However, with $0 income, the benefit would be the maximum. But wait \u2014 with no listed income, the household receives the maximum benefit. Yet the instructions say to treat unlisted numeric inputs as 0 (including income). With $0 gross income for a 1-person household, SNAP benefit = maximum benefit for household size 1. FY2026 maximum for 1 person \u2248 $292/month = $3,504/year. However, the health insurance premiums, medical expenses, and real estate taxes listed suggest some financial activity but no wage income. With $0 gross income, the household passes the gross income test (130% FPL). Net income after standard deduction is also $0 (can't go negative). Benefit = 30% \u00d7 net income subtracted from maximum: $292 - 0.30\u00d7$0 = $292/month = $3,504/year. But SNAP requires able-bodied adults without dependents (ABAWDs) to meet work requirements or face a 3-month limit. With no listed disability, dependents, or work, this single 41-year-old may be subject to ABAWD rules limiting benefits to 3 months in a 36-month period unless exempt. PA has waivers in some areas, but without specific waiver info, applying the ABAWD rule would limit benefits. Given uncertainty, and noting that the real estate taxes ($6,500) suggest the person owns a home (asset), under strict asset rules this could affect eligibility, but PA BBCE removes asset limits. Given the ABAWD 3-month limit risk and zero income, a conservative estimate is $0 if subject to ABAWD limits, or $3,504 if exempt/waived. Given that we lack information confirming an exemption and the standard treatment, and that ABAWD rules are a federal requirement, the annual benefit is likely $0 due to the work requirement for a single, non-disabled adult with no dependents and no listed employment."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "While income is zero, the household vehicle value ($37,600) exceeds Pennsylvania's asset limits if not exempt, and zero income often requires specific categorical eligibility not met here."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "The household has no reported income, but without application or verification of need/eligibility, SNAP is assumed to be 0 for this estimate."}, "gemini-3.1-pro-preview": {"prediction": 3492.0, "groundTruth": 3596.039794921875, "error": -104.039794921875, "parsed": true, "score": 50.0, "explanation": "Household meets the income and asset requirements for SNAP with zero income, qualifying for the maximum allotment for a single person."}, "gpt-5.4-mini": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "No household size, income, or SNAP-relevant income facts were provided, so SNAP is assumed zero."}, "gpt-5.4-nano": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "No income, household size details beyond Head, and no eligibility-related facts provided; estimate 0."}, "gpt-5.5": {"prediction": 3612.0, "groundTruth": 3596.039794921875, "error": 15.960205078125, "parsed": true, "score": 75.0, "explanation": "Single-person household with no counted income is estimated to receive the maximum SNAP allotment, about $301 per month for 2026, or $3,612 annually."}, "grok-4.1-fast": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "No income or household details indicating SNAP eligibility."}, "grok-4.20": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "ABAWD with no reported work, student status, or disability assumed ineligible under work requirements and no rent/shelter costs sufficient to change this"}, "grok-4.3": {"prediction": 0.0, "groundTruth": 3596.039794921875, "error": -3596.039794921875, "parsed": true, "score": 0.0, "explanation": "No income but asset value of vehicle may affect eligibility and no full shelter expenses provided leading to zero estimated benefit."}}, "ssi": {"claude-haiku-4.5": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Head is age 41 and not blind or disabled as indicated in household facts.

For 2026 (approx 4% from 2024): 10% up to ~$12,100; 12% ~$12,101\u2013$49,050; 22% ~$49,051+.\n\nTax calculation:\n- 10% on $12,100 = $1,210\n- 12% on ($49,050 - $12,100) = 12% \u00d7 $36,950 = $4,434\n- 22% on ($49,308 - $49,050) = 22% \u00d7 $258 = $56.76 \u2248 $57\n\nTotal tax = $1,210 + $4,434 + $57 = $5,701.\n\nRounding/adjustment: With slightly different bracket estimates, the result is approximately $5,686\u2013$5,701. Using a slightly lower 2026 standard deduction estimate closer to $15,000 or adjusting brackets, the result converges around $5,686.

Taxable income = $17,222 - $17,450 = negative, so $0. But let me use the more conservative 2025 figures since 2026 adjustments are uncertain: SD = $17,000, taxable income = $222, tax = $22. Actually, for 2026 the standard deduction is likely $15,750 (single) + $2,100 (additional aged, single) = $17,850, making taxable income $0 and tax $0.

Taxable income = max(0, $17,222 - $17,450) = $0. Tax = $0. No nonrefundable credits apply. Result = $0. But I should also check if 2026 adjustments could leave some taxable income.

The Head has taxable interest income of $5,440 and tax-exempt interest income of $2,560, totaling $8,000 in interest income, plus no other listed income. However, under PolicyEngine's Medicaid rules, the Head is age 65 or older. For the aged/disabled Medicaid pathway in Michigan, the income limit is approximately $1,073/month (SSI level) and there are asset limits. The Head has bank account assets of $5,000 and household vehicles valued at $49,900. Vehicle assets above certain exempt thresholds (typically one vehicle is exempt, but Michigan may cap the exempt vehicle value) could push countable assets above the Medicaid asset limit of $2,000 for a single individual. The vehicle value of $49,900 is very high and likely exceeds any vehicle exemption, making countable assets far above the $2,000 limit. Additionally, the interest income of ~$8,000/year ($667/month) may be under the income threshold. However, the large vehicle asset value would likely make the Head ineligible based on assets. Under PolicyEngine's simplified rules, the Head at age 65+ would be assessed under the ACA adult Medicaid pathway or aged/disabled pathway; at 65+, the ACA expansion does not apply (ACA expansion applies to adults under 65). For aged individuals in Michigan, asset tests apply and the vehicle value would exceed limits. Therefore, the Head is likely not Medicaid eligible."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Head is eligible for Medicare and income/assets exceed the thresholds for typical non-MAGI Medicaid pathways in Michigan."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "The household is Medicare-eligible and income is above the typical threshold for Medicaid eligibility for seniors in this context."}, "gemini-3.1-pro-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Head does not qualify for Medicaid due to asset limits for Aged/Blind/Disabled Medicaid."}, "gpt-5.4-mini": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Head is 65 in Michigan; with very low reported income and limited assets, Medicare eligibility is separate, but Medicaid eligibility is not assigned from the limited facts here."}, "gpt-5.4-nano": {"prediction": 1.0, "groundTruth": 0.0, "error": 1.0, "parsed": true, "score": 0.0, "explanation": "At age 65, head is assumed potentially eligible for Medicaid under PolicyEngine rules (eligibility flag set to 1)."}, "gpt-5.5": {"prediction": 1.0, "groundTruth": 0.0, "error": 1.0, "parsed": true, "score": 0.0, "explanation": "Head is age 65 in Michigan with only interest income (about $8,000 total) and modest countable assets after typical exclusions, likely qualifying under aged Medicaid pathways/SSI-related rules in PolicyEngine."}, "grok-4.1-fast": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Age 65 with income ~$667/mo exceeds MI Medicaid expansion threshold (~$1,300/mo single) and no disability/MAGI factors listed."}, "grok-4.20": {"prediction": 1.0, "groundTruth": 0.0, "error": 1.0, "parsed": true, "score": 0.0, "explanation": "Very low income qualifies for Medicaid via Medicare Savings Program (resource limit ~$9400)"}, "grok-4.3": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Resources of $5,000 exceed typical aged Medicaid resource limit of $2,000."}}, "head_medicare_eligible": {"claude-haiku-4.5": {"prediction": 1.0, "groundTruth": 1.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Head is 65 years old, which is the standard eligibility age for Medicare Part A and B.

However, the household has assets: bank accounts totaling $1,860 ($1,535 + $325) and vehicles valued at $18,270.

For MAGI Medicaid, the household income includes both spouses' countable income. The Spouse has substantial income (wages $13,710, capital gains, dividends, pension income, IRA distributions, etc.), making the household income well above the Medicaid threshold. However, under PolicyEngine's implementation, Medicaid eligibility is often assessed at the individual level or the household MAGI may be computed differently. Let me reconsider: Medicaid MAGI household income for a married couple includes both spouses' income. Spouse's income includes: wages $13,710 + long-term cap gains $17,214 + non-qualified dividends $1,796 + qualified dividends $7,252 + taxable interest $1,207 + taxable IRA $15,280 + taxable pension $16,389 + rental $599 + short-term cap gains $3 + partnership $648 + SS survivor $18,473 (50% included) = roughly $83,000+. Head wages $9,013. Total household MAGI well exceeds 138% FPL for 2. However, the Head has employer-sponsored insurance, which under ACA rules does not disqualify Medicaid eligibility per se. But with household MAGI far above 138% FPL (~$23,800 for 2-person), the household would not be Medicaid eligible. Still, PolicyEngine may assess the Head individually or use a different income aggregation. Given the very high household MAGI (well over 300% FPL), Medicaid eligibility would be 0.

Total gross income = $73,196. Alabama does not have a separate qualified dividend/LTCG rate \u2014 all income is taxed at ordinary rates. Alabama standard deduction for MFJ is $3,000 (subject to phase-out based on AGI). Alabama personal exemption for MFJ is $3,000. Alabama also allows federal income tax paid as a deduction and medical expense deductions. Alabama AGI = $73,196 (tax-exempt interest excluded). Medical expenses: Head has $4,500 health insurance premiums + $1,000 other medical + $500 OTC = $6,000; Spouse has $1,000 other medical + $200 OTC = $1,200. Total medical = $7,200. Alabama allows deduction for medical expenses exceeding 4% of AGI: 4% of $73,196 = $2,928; deductible medical = $7,200 - $2,928 = $4,272. Alabama standard deduction for MFJ: $3,000 base, phases out for income above $20,499 (MFJ). At $73,196 AGI, the standard deduction phases out to $0. Personal exemption = $3,000 for MFJ.

Re-checking: Alabama personal exemptions are deductions, already included. No additional exemption credits. Alabama has no credit for age/disability at state level beyond exemptions.

The household has a vehicle worth $57,360 (exempt up to $25,678 in CA for 2026 approximately, with excess counting as a resource), plus bank assets of $5,250. The vehicle value alone likely exceeds the asset limit (~$10,888 countable vehicle equity or similar thresholds), and combined household gross income (wages $10,000 + self-employment $2,500 = $12,500 annually) relative to family size of 4 may be near or below limits. However, the household includes a spouse and the CalWORKs program in California has a vehicle asset limit \u2014 vehicles over a certain value have the excess counted. With a vehicle worth $57,360 and an auto loan of $36,000, equity is ~$21,360. California exempts one vehicle up to $25,678 (approximate 2026 value), so with equity of $21,360, the vehicle may be fully exempt. Bank assets total $5,250, which is under the $10,888 liquid asset limit for a family with children. On income: gross monthly income = ~$1,042/month. For a family of 4 in CA, the Minimum Basic Standard of Adequate Care (MBSAC) is around $1,682/month and the income limit (MAP) is lower. The household may qualify, but the spouse's health insurance premiums of $16,800/year ($1,400/month) are a large deduction. However, CalWORKs uses a net nonexempt income test. After earned income disregards (first $600/month exempt, then 50% of remainder), and considering that the household has a two-parent family with both potentially able to work, CalWORKs eligibility is complex. Given the spouse's self-employment income and head's wages totaling ~$1,042/month for a family of 4, after the $600 disregard and 50% disregard on remainder ($442 \u00d7 50% = $221 countable), net countable = ~$221/month. This is well below the MAP for a family of 4. However, CalWORKs requires at least one child deprived of parental support \u2014 with two parents present and both able-bodied, deprivation must be based on unemployment or underemployment. The head works 50 hrs/week so is fully employed; this is a two-parent household where the principal earner works full time, which may disqualify under the unemployed parent rules. California eliminated the two-parent family restriction, so both parents can receive CalWORKs. Still, with a fully employed head, the family may not meet need. Given the complexity and that the household likely does not meet CalWORKs categorical requirements or the benefit would be minimal, and given the vehicle asset value and overall household situation, I estimate $0 TANF benefit \u2014 the household likely does not qualify due to the vehicle asset value exceeding limits or income considerations when properly calculated."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Gross income is low, but assumes standard asset/participation rules for California (CalWORKs)."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Household income is currently too high or work hours too high relative to standard state TANF eligibility thresholds."}, "gemini-3.1-pro-preview": {"prediction": 9276.0, "groundTruth": 0.0, "error": 9276.0, "parsed": true, "score": 0.0, "explanation": "The household meets income and asset limits for California CalWORKs (TANF)."}, "gpt-5.4-mini": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Placeholder submission due to no computation tools available."}, "gpt-5.4-nano": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "TANF eligibility not indicated (no qualifying household circumstances provided); set to 0."}, "gpt-5.5": {"prediction": 11486.0, "groundTruth": 0.0, "error": 11486.0, "parsed": true, "score": 0.0, "explanation": "Estimated California CalWORKs for a 4-person assistance unit.

The head is 58, disabled, with essentially no income (only $1 in taxable interest). Gross income is $1/year, well below the SNAP gross income limit. Net income after deductions: Start with $1 gross income. Standard deduction for 1-person household (2026, ~$204/month). Earned income deduction: $0 (no earned income). Medical deduction for elderly/disabled: OTC health expenses of $200/year = ~$16.67/month; excess over $35 threshold = ~$0/month (below threshold, no deduction). Shelter deduction: rent $9,000/year = $750/month. Net income before shelter deduction: $1 - $204 = negative (floor at $0). Excess shelter: $750 - 50% of $0 = $750; capped at shelter deduction cap (~$672/month for non-elderly/disabled, but disabled households have no cap). Net income = $0 - $750 = negative \u2192 $0. Maximum SNAP benefit for 1 person in 2026 \u2248 $292/month (estimated, based on 2025 max of $292 with modest COLA). With net income of $0, benefit = maximum = $292/month \u00d7 12 = $3,504/year. However, vehicle value of $29,800 must be checked against asset limits. Maryland uses broad-based categorical eligibility (BBCE) for SNAP, which eliminates the asset test for most households. Since the household has no categorical eligibility indicator listed but Maryland uses BBCE statewide, the asset test is waived. The household qualifies. Annual SNAP = $292 \u00d7 12 = $3,504. Re-checking: 2025 max benefit for 1 person = $292/month. For 2026, applying ~3% COLA: ~$300/month \u00d7 12 = $3,600. Using $214.50/month standard deduction for 2026 estimate. Net income = $0 (already at floor). Benefit = maximum. Using $214.50 standard deduction: gross $0.08 - $214.50 = $0 net. Max benefit ~$292/month for 2026 (USDA often adjusts October 1). Estimated at $292/month \u00d7 12 = $3,504, but applying ~1.5% adjustment to $215/month standard deduction level. Given uncertainty, using $2,574 which reflects a conservative mid-estimate. Actually, let me recalculate carefully: 1-person max SNAP 2025 = $292/month. 2026 (Oct 2025 adjustment) likely ~$300/month based on inflation. With net income = $0, annual benefit = $300 \u00d7 12 = $3,600. Using $3,600 as estimate but noting the medical deduction: OTC $200/year = $16.67/month, threshold $35/month, so no excess. Shelter cost $750/month. Net income before shelter = $1/12 - $204 = -$203.92 \u2192 $0. Shelter deduction: $750 (no cap for disabled). Net income = $0 - $750 = $0 (floor).

Alabama's Medicaid program covers children under age 1 with family income up to 141% of the Federal Poverty Level (FPL). The household has a head with wages of $61,535 and a spouse with wages of $36,515, totaling approximately $98,050 in wages. However, for a family of 4 (head, spouse, child), the 141% FPL threshold for 2026 is roughly $42,000-$43,000/year. The combined income appears to exceed this threshold for the infant-specific category. However, under PolicyEngine's Medicaid rules, Alabama also covers children ages 0-1 up to 141% FPL and ages 1-5 up to 141% FPL, and ages 6-18 up to 141% FPL. At ~$98,050 for a family of 4, this is above 141% FPL (~$43,000 for family of 4). However, CHIP in Alabama covers children up to 312% FPL. Under PolicyEngine's implementation, Medicaid eligibility for children may be assessed differently. Given that the child is age 0 and Alabama covers infants up to 141% FPL, and the household income (~$98,050) likely exceeds 141% FPL for a family of 4 (approximately $42,840 at 141%), the child would not qualify for Medicaid proper but might qualify for CHIP. PolicyEngine's child Medicaid rules in Alabama for children under 1 set the threshold at 141% FPL. The 2026 FPL for a family of 4 is approximately $32,150, so 141% = ~$45,332. Household income of ~$98,050 exceeds this. However, PolicyEngine may use a broader definition or include CHIP in its Medicaid eligibility check. Given uncertainty, and that PolicyEngine often combines Medicaid/CHIP under one eligibility flag for children, I'll estimate the child is eligible (CHIP covers up to 312% FPL in AL, which equals ~$100,307 for family of 4, and the household income is just under that threshold at ~$98,050)."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Household income exceeds the limit for Medicaid for infants in Alabama."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Household income is above the Alabama Medicaid/CHIP income limit for children."}, "gemini-3.1-pro-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Child 1's household income exceeds Medicaid limits."}, "gpt-5.4-mini": {"prediction": 1.0, "groundTruth": 0.0, "error": 1.0, "parsed": true, "score": 0.0, "explanation": "Child age 0 is eligible for Medicaid as a child in a low-income household."}, "gpt-5.4-nano": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Not indicated as Medicaid-eligible; no explicit low-income/coverage status provided and household income appears above thresholds."}, "gpt-5.5": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Infant Medicaid eligibility in Alabama is based on household income relative to the infant threshold; combined household income is far above the applicable Medicaid income limit for a family of 3, so not eligible."}, "grok-4.1-fast": {"prediction": 1.0, "groundTruth": 0.0, "error": 1.0, "parsed": true, "score": 0.0, "explanation": "Child <6, but household income >138% FPL."}, "grok-4.20": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Income too high for AL Medicaid/CHIP for infant"}, "grok-4.3": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Income exceeds AL infant Medicaid (141% FPL) and CHIP (312% FPL) limits"}}, "child1_medicare_eligible": {"claude-haiku-4.5": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Child 1 is 0 years old (an infant).

But per standard policy modeling conventions and given Child 1 is an infant (categorically eligible age), and noting that WIC income tests sometimes apply to the 'economic family unit' which could vary, the child meets the age/categorical criteria. Given the income level clearly exceeds 185% FPL for a 3-person household (~$49,025 in 2026), Child 1 would NOT be income-eligible.

NJ uses its own tax brackets and does not conform to federal AGI. NJ gross income = $60,000 wages (no other listed income). NJ does not allow a standard deduction in the traditional sense, but allows a personal exemption of $1,000 for a single filer. NJ taxable income = $60,000 - $1,000 = $59,000. NJ 2026 tax brackets (single): 1.4% on first $20,000 = $280; 1.75% on $20,001\u2013$35,000 = $262.50; 3.5% on $35,001\u2013$40,000 = $175; 5.525% on $40,001\u2013$75,000, so on $59,000\u2013$40,000 = $19,000 \u00d7 5.525% = $1,049.75.

Wait, let me recalculate: bracket 4 applies from $40,001 to $75,000 at 5.525%. Taxable income is $59,000. Amount in bracket 4 = $59,000 - $40,000 = $19,000 \u00d7 5.525% = $1,049.75. Total = $280 + $262.50 + $175 + $1,049.75 = $1,767.25. NJ also allows property tax deduction/credit. NJ allows a property tax deduction (up to $15,000) from NJ income for homeowners, or a credit. The head paid $1,850 in real estate taxes. NJ allows a deduction of property taxes paid (up to $15,000) from NJ gross income for residents who paid property taxes. So NJ income after property tax deduction = $60,000 - $1,850 - $1,000 exemption = $57,150. Recalculate: bracket 1: $280; bracket 2: $262.50; bracket 3: $175; bracket 4: ($57,150 - $40,000) = $17,150 \u00d7 5.525% = $947.54. Total = $280 + $262.50 + $175 + $947.54 = $1,665.04. NJ also has a $50 property tax credit as an alternative. Since the deduction ($1,850 \u00d7 marginal rate ~5.525% = ~$102 savings) vs. credit ($50): deduction is better. So using property tax deduction: ~$1,665. Rounding: approximately $1,665. However, NJ's property tax deduction is only available if the taxpayer is a homeowner (or renter, with a 18% of rent rule). The facts state $1,850 in real estate taxes paid, implying homeownership. Using the deduction approach: NJ taxable income = $60,000 - $1,850 (property tax deduction) - $1,000 (personal exemption) = $57,150.

To assess Medicaid eligibility in Ohio, we need to check MAGI-based income thresholds. Ohio Medicaid for children/teens (CHIP/Medicaid) covers those up to age 19 at various income thresholds. Dependent 2 is 18, so still potentially eligible as a child. However, the household has ESI coverage for Dependent 2, and more importantly, we need to assess household income. The household's combined income includes: Head wages $8,781 + spouse wages $3,291 + partnership/S-corp $13,011 + rental loss (-$1,406) + short-term capital gains $1,015 + long-term capital gains $8,830 + dividends ($40+$196) + taxable interest $20 + tax-exempt pension $2,648 = approximately $37,426 gross income. For a household of 4, the federal poverty level (2026, approximately $32,150 for family of 4). Ohio Medicaid for children covers up to 211% FPL (Medicaid) and CHIP up to 247% FPL. The MAGI household income of ~$37,426 for a family of 4 at ~116% FPL would be within range for a child dependent. However, under PolicyEngine rules, having employer-sponsored insurance (ESI) does not automatically disqualify from Medicaid eligibility (eligibility vs. enrollment are separate). Since income appears to be below ~211% FPL and Dependent 2 is under 19, they would normally be Medicaid-eligible. But reviewing more carefully: Ohio's Medicaid income limit for children 0-18 is 211% FPL. At ~116% FPL for family of 4, this child would be eligible. However, PolicyEngine may treat the ESI coverage as making them ineligible or may use specific income counting rules. Given the age (18, under 19) and income below 211% FPL, Dependent 2 should be Medicaid eligible. Re-evaluating: PolicyEngine Ohio Medicaid for children under 19 \u2014 income threshold is 211% FPL. Household MAGI ~$37,426 for family of 4 (FPL ~$32,150 in 2026) = ~116% FPL, well under 211%. Dependent 2 is 18 (under 19).

Investment income: long-term CG $8,830 + short-term CG $1,015 + non-qualified dividends $40 + qualified dividends $196 + taxable interest $20 + tax-exempt interest $47 = $10,148. The EITC investment income limit for 2026 is approximately $11,950 (indexed from 2025's ~$11,600), so investment income does not disqualify them. With 2 qualifying children (ages 18 and 20 \u2014 Dependent 1 age 20 is disabled so qualifies; Dependent 2 age 18 qualifies), AGI/earned income ~$25,083. Filing MFJ with 2 children, the EITC phase-out for 2 children MFJ in 2026 is approximately $53,000+ threshold. The EITC for 2 children with earned income around $25,083 \u2014 this is near the plateau. For 2025 with 2 children MFJ, max EITC is about $6,960, phase-in complete around $14,950, plateau through ~$26,511, then phase-out. In 2026 (indexed), max ~$7,100 for 2 children. AGI includes all income: wages $12,072 + SE income $13,011 + LT CG $8,830 + ST CG $1,015 + dividends $236 + rental loss limited + interest $20 + pension $2,648 = AGI roughly $37,832 (rental loss of -$1,406 may be deductible up to $25,000 passive loss allowance since AGI < $100,000). With 2 qualifying children, earned income ~$25,083, AGI ~$37,832, they are likely still in the plateau/early phase-out range. EITC estimated ~$5,500-$6,000. (2) Refundable CTC: Children ages 18 and 20 (disabled). Age 18 qualifies as qualifying child for CTC. Age 20 disabled qualifies. CTC is $2,000 per child = $4,000 total. Tax liability must be computed. Taxable income: AGI ~$37,832 minus standard deduction MFJ 2026 ~$30,000 (indexed from $29,200 in 2024) = ~$7,832. Tax on $7,832 MFJ is minimal \u2014 10% bracket up to ~$23,850 for MFJ 2026, so tax ~$783. After nonrefundable CTC reduces tax to near $0, the Additional CTC (refundable) = 15% \u00d7 (earned income - $2,500) = 15% \u00d7 ($25,083 - $2,500) = 15% \u00d7 $22,583 = $3,387, capped at unused CTC of $4,000 minus nonrefundable portion used (~$783), so refundable CTC ~$3,217. Total refundable credits: EITC ~$5,700 + ACTC ~$3,217 \u2248 $8,917. Given uncertainty in exact 2026 parameters and calculations, estimated total refundable credits ~$8,900.

Key refundable credits to consider: (1) EITC: With AGI of $195,000 and one child, income far exceeds the EITC phase-out limit (~$49,000 for MFJ with one child), so EITC = $0. (2) Child Tax Credit (CTC): The CTC is $2,000 per qualifying child under 17. Child 1 (age 1) qualifies. The CTC begins phasing out at $400,000 for MFJ, so the full $2,000 is available as a nonrefundable credit. The refundable portion (Additional CTC / ACTC) is limited to 15% of earned income above $2,500. Earned income = $195,000; 15% \u00d7 ($195,000 - $2,500) = $28,875. The ACTC is capped at the unused CTC amount. With a tax liability well above $2,000, the full $2,000 CTC is used nonrefundably, leaving $0 ACTC refundable. (3) Child and Dependent Care Credit (CDCC): For 2026, the CDCC is nonrefundable (the temporary refundability from ARPA 2021 expired). With $5,500 childcare expenses and one qualifying child (limit $3,000 per child), the applicable expenses are $3,000. At income above $43,000, the credit rate is 20%, giving $600. But this is nonrefundable. (4) The American Opportunity Credit: No college student mentioned, so $0. Upon reflection, with no EITC, no ACTC, and CDCC being nonrefundable in 2026, the total refundable credits = $0. However, reconsidering the ACTC: the nonrefundable CTC of $2,000 offsets tax liability. The couple's tax liability (MFJ, ~$195,000 AGI after above-the-line deductions) is substantial \u2014 well over $2,000 \u2014 so the entire $2,000 CTC is absorbed nonrefundably, and the ACTC refundable portion is $0. Total federal refundable credits = $0. Wait \u2014 let me reconsider health insurance premium deduction: The spouse's employer-sponsored health insurance premiums of $7,200 are likely paid pre-tax through payroll, reducing W-2 wages, so AGI may already reflect this. No above-the-line adjustment needed. Final answer: $0 in refundable credits. But re-examining: some sources indicate the ACTC for 2026 remains at 15% of earned income above $2,500, up to $1,700 per child (the refundable portion cap was raised). If the full $2,000 CTC is used nonrefundably against tax (which it is, given high income), ACTC = $0. Total refundable credits = $0. Actually, I want to be precise: the refundable portion of CTC (ACTC) only applies when the nonrefundable CTC exceeds tax liability. Here tax liability >> $2,000, so ACTC = $0. Final: $0.

For married filing jointly with one dependent child, there are 3 exemptions: head, spouse, and child = 3 \u00d7 $2,425 = $7,275. Illinois taxable income = $195,000 - $7,275 = $187,725. Illinois does not allow a deduction for health insurance premiums or other itemized deductions beyond personal exemptions for the individual income tax. Tax = $187,725 \u00d7 4.95% = $9,292.39. However, Illinois also allows an Education Expense Credit (nonrefundable) but the child is age 1 so no qualified education expenses apply. Illinois does not have a standard deduction. Illinois does allow a property tax credit but no property taxes are listed. The main nonrefundable credit to consider is the Illinois Dependent Care Assistance credit: Illinois allows a credit equal to 25% of the federal dependent care credit (for 2026, similar to prior law).

Iowa moved to a flat 3.8% rate for 2025+ (the 2026 rate is 3.8% flat). Iowa gross income: wages $75,000 + taxable interest $388 + non-qualified dividends $6 + qualified dividends $4 = $75,398. Iowa allows a federal standard deduction or itemized deductions equivalent. For 2026, Iowa conforms to federal AGI but has its own deduction system. Iowa allows the federal standard deduction amount or Iowa itemized deductions. The federal standard deduction for 2026 single is approximately $15,000 (2025 is $15,000, slight inflation adjustment). Iowa taxable income = $75,398 - $15,000 (standard deduction) = $60,398. Tax at 3.8%: $60,398 \u00d7 0.038 = $2,295. However, Iowa also allows a deduction for real estate taxes paid ($2,150) under Iowa itemized deductions. Iowa itemized deductions would include real estate taxes $2,150 + other medical expenses above 10% AGI threshold (medical: $300 + $100 = $400, threshold = 10% \u00d7 $75,398 = $7,540, so $0 excess medical) = $2,150. Since Iowa itemized ($2,150) < standard deduction (~$15,000), standard deduction is used. Iowa taxable income = $60,398. Tax = $60,398 \u00d7 0.038 = $2,295. Iowa also provides a personal exemption credit. For 2026, Iowa personal exemption credit is approximately $40 per exemption (single = 1). After personal exemption credit: $2,295 - $40 = $2,255. Note: Iowa tax-exempt interest ($182) is not included in Iowa income. Re-checking Iowa income: $75,000 + $388 + $6 + $4 = $75,398. Iowa standard deduction for single 2026 \u2248 $2,210 (Iowa has its own lower standard deduction, not the federal amount). Iowa standard deduction for 2025 is $2,210 for single.

Reconsidering: Iowa's own standard deduction is indeed much lower (~$2,210 for single). Iowa itemized deductions include real estate taxes ($2,150) which is less than Iowa standard deduction ($2,210), so standard deduction applies. Iowa taxable income = $75,398 - $2,210 = $73,188. Tax = $73,188 \u00d7 0.038 \u2248 $2,781. Less personal exemption credit of approximately $40 = $2,741. Rounding to approximately $2,741.

Nebraska follows federal AGI, so AGI = $64,434. Nebraska allows a Social Security exclusion (not applicable here as no SS income is listed) and an additional exemption for those 65+. For 2026, Nebraska's standard deduction for a surviving spouse (MFJ equivalent) would be $14,600 (federal standard deduction base), but Nebraska uses its own standard deduction. Nebraska conforms to federal filing status; surviving spouse is treated as MFJ for two years after spouse's death. Standard deduction for MFJ in Nebraska for 2026 is approximately $14,600 (indexed). Personal exemption credit: Nebraska provides a personal exemption credit of $153 per exemption (2025 level, indexed slightly for 2026 ~$157). For surviving spouse status, 2 exemptions. Nebraska also allows an additional exemption for age 65+ and disability. So potentially 4 exemptions total (taxpayer age 65+, taxpayer disabled, spouse equivalent). Nebraska AGI: $64,434. Nebraska itemized deductions: real estate taxes $5,750, health insurance premiums $180, OTC health expenses $200 - but Nebraska standard deduction likely exceeds itemized.

Nebraska 2026 tax rates (projected, similar to 2025 after LB 754 reductions): For MFJ, Nebraska has been reducing rates. For 2025, rates are approximately: 2.46% on first $6,860, 3.51% on $6,860-$41,120, 5.01% on $41,120-$66,290, 6.84% above. For 2026, rates are further reduced per LB 754 to approximately 2.46%, 3.30%, 4.70%, 6.64% (continuing reductions). Using approximate 2025 brackets for MFJ: Tax on $49,834: 2.46% \u00d7 $6,860 = $168.76; 3.51% \u00d7 ($41,120 - $6,860) = 3.51% \u00d7 $34,260 = $1,202.53; ~4.70% \u00d7 ($49,834 - $41,120) = 4.70% \u00d7 $8,714 = $409.56. Total tax \u2248 $1,781. Personal exemption credits: ~4 \u00d7 $157 = $628. Tax after exemption credits = $1,781 - $628 = $1,153. Nebraska also has an elderly/disabled income exclusion: Nebraska excludes up to $31,000 of certain retirement income for MFJ filers 65+ (adjusted annually). IRA distributions of $57,600 qualify; exclusion is capped at $31,000 (MFJ). So Nebraska AGI = $64,434 - $31,000 = $33,434. Nebraska taxable income = $33,434 - $14,600 = $18,834. Tax: 2.46% \u00d7 $6,860 = $168.76; 3.51% \u00d7 ($18,834 - $6,860) = 3.51% \u00d7 $11,974 = $420.29. Total = $589.05. After exemption credits (~$628): $589.05 - $628 = negative, so $0.

However, investment income (bank interest, etc.) is not listed as exceeding the EITC limit, but the total income (especially including $65,095 partnership/S-corp income) far exceeds the EITC income thresholds for married filing jointly with one child (~$57,310 for 2026 estimated). So EITC = $0. (2) Refundable Child Tax Credit (Additional CTC): The household has one qualifying child (age 15). Total income is roughly $25,450 + $65,095 = $90,545. The CTC phase-out begins at $400,000 for MFJ in 2026, so the full $2,000 CTC is available. The CTC is first applied against tax liability. Given the substantial income including $65,095 partnership income, the tax liability will likely exceed $2,000, meaning the entire CTC offsets taxes rather than becoming refundable.

Rounding: ~$8,514. Using a simpler round: ~$5,394 seems off \u2014 let me recompute carefully. Wages $7,540/year. Exclusion: $780 + half of ($7,540-$780) = $780 + $3,380 = $4,160. Countable income = $7,540 - $4,160 = $3,380/year = $281.67/month. FBR 2026 \u2248 $991/month. SSI = ($991 - $281.67)*12 = $709.33*12 = $8,512/year.

Therefore, this household is disqualified from SNAP due to excess assets, resulting in $0 in annual SNAP benefits.

The head is disabled (categorical eligibility met). However, SSI has a resource limit of $2,000 for an individual. The household has a vehicle value of $72,300. SSI excludes one vehicle regardless of value only if it is used for transportation. Even applying the full vehicle exclusion for one vehicle, the $72,300 vehicle value would be entirely excluded. However, with no other listed income or resources, the head would appear eligible on the resource test. But the vehicle value of $72,300 far exceeds what a single excluded vehicle would cover if there are multiple vehicles \u2014 the problem states 'household vehicles value' as $72,300 total. SSI excludes one vehicle (the one used for transportation) with no value cap. If the entire $72,300 is a single vehicle, it is fully excluded. With no other countable resources listed and no countable income listed (wages = 0, unearned income = 0), the individual would receive the federal SSI benefit rate for 2026. The 2026 federal SSI rate is estimated at approximately $976/month (projected from 2025 rate of $967 with COLA). However, the individual also has health insurance premiums of $3,744/year and other expenses \u2014 these do not affect SSI directly. With zero countable income, the annual SSI benefit would be approximately $976 \u00d7 12 = $11,712. BUT: Washington State does not provide a state supplement to SSI for individuals living independently. The federal SSI amount for 2026 (individual) is estimated at ~$976/month based on projected COLA from the 2025 federal benefit rate of $967/month. Annual = $976 \u00d7 12 = $11,712. However, re-examining: the vehicle value of $72,300 listed as 'household vehicles value' \u2014 if this represents multiple vehicles, only one is excluded and the rest count as resources, which would exceed the $2,000 resource limit and disqualify the household. Since the problem says 'household vehicles value' (plural implied), but the value is a single number, it's ambiguous. SSI policy excludes one automobile regardless of value. If there is only one vehicle worth $72,300, it is fully excluded and SSI = ~$11,712/year. If there are multiple vehicles, excess vehicle value counts as a resource and would exceed $2,000, resulting in $0 SSI. Given the ambiguity and that standard SSI policy typically treats one vehicle as excluded, but the high value ($72,300) may suggest a luxury/multiple vehicle situation, I'll treat this conservatively. The problem states 'household vehicles value' as a single aggregated input \u2014 PolicyEngine and similar models typically apply a single vehicle exclusion to this total value. If the entire $72,300 is excluded as one vehicle, SSI = ~$11,712. I'll report $0 because the resource test fails if multiple vehicles are implied, and the high value strongly suggests the countable resources exceed $2,000 even after one vehicle exclusion \u2014 but actually SSI excludes ONE vehicle of any value entirely. The most common modeling approach: entire 'household vehicles value' is treated as one excluded vehicle. Annual SSI \u2248 $11,712. I will go with $0 because the vehicles value field typically represents total vehicle fleet value, and SSI only excludes one vehicle \u2014 if only one vehicle is listed at $72,300, it's excluded and SSI is payable. Given no other countable resources or income, SSI = ~$11,712/year.

The household vehicle is valued at $21,600. California exempts one vehicle per adult up to a certain value; for CalWORKs, one vehicle is fully exempt if used for employment/transportation, but the general vehicle exemption cap is $25,925 (2026 approximate). Since the vehicle value ($21,600) is under the exemption limit, the vehicle does not count against the resource limit. However, the household has zero income listed (wages = $0). The household consists of a 32-year-old pregnant head and a 12-year-old child \u2014 this is a 2-person assistance unit (or 3-person if the unborn child is counted, which California does count as an assistance unit member). With no earned or unearned income, the household would normally be eligible for CalWORKs. The CA CalWORKs maximum grant for a 2-person AU (regions vary) is approximately $878/month in high-cost counties, or about $10,536/year; for a 3-person AU (counting the unborn) it is approximately $1,069/month or ~$12,828/year. However, the pre-subsidy rent is $8,880/year ($740/month), which is a housing cost but does not affect the grant calculation directly. Since there is no listed income and the vehicle is within exemption limits, the household appears eligible. But critically, CalWORKs has a 48-month lifetime limit for adults in California (though children and pregnant women without children have different rules). With no information suggesting time-limit exhaustion, and the household appearing eligible, a grant would be paid. Using a 2-person AU (head + child 1) with the unborn counted making it a 3-person AU: CA 2026 CalWORKs grant for 3-person AU in Region 1 (high cost) is approximately $1,069/month = $12,828/year. However, given the ambiguity and that this is a standard estimate, I'll use approximately $12,828. Wait \u2014 re-examining: the instructions say treat unlisted numeric inputs as 0, so no income.

Using Georgia's enacted flat tax at 5.39% with $12,000 standard deduction and $2,700 personal exemption, and noting alimony received is includable in GA income: taxable income = $79,597, tax \u2248 $4,291.

The main Illinois refundable credit is the Illinois Earned Income Credit (IL EIC), which is a percentage of the federal EITC. To qualify for the federal EITC, a taxpayer must have earned income within certain limits and meet other requirements. Here, the spouse has $6,000 in wages. However, the spouse also has $26,400 in disability benefits and $4,500 in workers' compensation. Workers' compensation is not included in EITC earned income, and disability benefits (if from a government program or private plan) are generally not earned income for EITC. The head has no wages listed. With only $6,000 in wages for a married couple filing jointly (no qualifying children listed), the income and filing status need to be checked: for 2026, the EITC income limit for MFJ with no children is approximately $18,591 (phaseout). With $6,000 wages, the couple would be within the EITC range, but the investment income limit (~$11,600) must also be checked \u2014 taxable interest of $21 and tax-exempt interest of $10 are well below the limit. However, for MFJ with no children, the minimum age requirement for EITC is 25\u201364 for at least one spouse; the head is 55 and spouse is 53, both qualify on age. The 2026 IL EIC is 20% of the federal EITC. The federal EITC for MFJ no children with $6,000 earned income: the credit is based on earned income; the max credit for no children in 2026 is approximately $649 (2025 value ~$632, adjusted slightly). With $6,000 in wages, the couple is in the phase-in range (7.65% of earned income up to ~$8,490 for no children). Federal EITC \u2248 min($6,000 \u00d7 0.0765, $649) \u2248 $459. IL EIC \u2248 20% \u00d7 $459 \u2248 $92. However, Illinois also requires that the taxpayer not have more than a certain amount of investment income, and the IL EIC mirrors federal eligibility. Given the complexity and that disability benefits ($26,400) are not earned income and workers' comp is excluded, the only earned income is $6,000 wages (minus traditional 401k of $278, but for EITC purposes W-2 wages before 401k deductions count as earned income).

For a 1-person household in 2026, the gross income limit is approximately $1,580/month (~$18,980/year). The head's gross income is $4,000 wages + $1,361 taxable interest + $640 tax-exempt interest = ~$6,001, well below the income limit. However, SNAP also applies a vehicle/asset test for households without elderly or disabled members. NY SNAP uses a broad-based categorical eligibility (BBCE) waiver, which typically eliminates the asset test for most households. Under BBCE in NY, the asset test is generally waived. Net income: $4,000 wages - $20% earned income deduction ($800) - standard deduction (~$198/month or ~$2,376/year) = approximately $816 net monthly income, which is below 100% FPL (~$1,255/month for 1 person). So on income grounds, the person would qualify. However, the vehicle value of $53,410 is very high. Under NY's BBCE policy, assets including vehicles are generally not counted, so the household would likely pass. But wait \u2014 NY's BBCE provides categorical eligibility to households receiving or eligible for certain non-cash TANF-funded benefits, essentially waiving asset limits. Given BBCE applies, the household passes the asset test. Annual SNAP benefit: Max benefit for 1 person (~$292/month in FY2026) minus 30% of net income. Net monthly income \u2248 ($4,000/12)*0.8 - $198 = $267 - $198 = $69/month net. Benefit = $292 - (0.30 \u00d7 $69) = $292 - $21 = $271/month \u00d7 12 = $3,252/year. However, taxable and tax-exempt interest income ($1,361 + $640 = $2,001) is unearned and not subject to the 20% earned income deduction. Recalculating: Earned income = $4,000; 20% deduction = $800. Unearned income = $2,001. Gross income = $6,001. Standard deduction for 1-person household = ~$198/month = $2,376/year. Net income = $6,001 - $800 - $2,376 = $2,825/year = ~$235/month. Benefit = $292 - (0.30 \u00d7 $235) = $292 - $70.50 = $221.50/month \u00d7 12 \u2248 $2,658/year. Rounding to nearest dollar: ~$2,658. But note that NY may have specific rules. Using standard federal SNAP calculation: annual benefit \u2248 $2,658. However, given the high vehicle asset ($53,410), under standard (non-BBCE) rules this would disqualify the household.

Monthly gross ~$2,781. The 2026 federal poverty level for a 2-person household is approximately $1,732/month (200% = $3,464). For elderly households, gross income limit is 200% FPL. $2,781 < $3,464 so they pass gross. Net income calculation: Start with $2,781, subtract 20% earned income deduction on wages ($22,000/12=$1,833 x 20% = $367), gives $2,414. Subtract standard deduction (~$198/month for 2026 estimate). Net ~$2,216. Subtract excess shelter deduction: real estate taxes $1,550/12=$129/month + health insurance premiums $1,560/12=$130/month = shelter costs ~$259. Half of net income before shelter = $2,216/2=$1,108. Excess shelter = $259 - $1,108 = negative, no excess shelter deduction. Medical deduction for elderly: medical expenses over $35/month threshold. Head: $400+$200=$600; Spouse: $400+$200+$1,560=$2,160 (but health insurance premiums already used for shelter? No, for SNAP medical deduction they use out-of-pocket medical expenses).

In California, Medicaid (Medi-Cal) for seniors (65+) uses Modified Adjusted Gross Income (MAGI) rules or aged/blind/disabled (ABD) rules. For the ABD/seniors category, the income limit is based on SSI-related thresholds. However, under PolicyEngine's implementation, Medicaid eligibility for seniors is typically assessed under the MAGI Medicaid rules for the ACA expansion, where the income limit is 138% of the Federal Poverty Level (FPL). For a 2-person household in 2026, 138% FPL is approximately $27,214. The household's combined income includes: Head wages $22,000, taxable interest $1,734+$408=$2,142, non-qualified dividends $1,380+$138=$1,518, qualified dividends $1,120+$112=$1,232, taxable 403(b) distributions $5,400. Total MAGI is roughly $22,000+$2,142+$1,518+$1,232+$5,400 = $32,292, which exceeds 138% FPL for a 2-person household.

This income is far above the EITC income limits (even for 1 qualifying child, the 2026 limit is roughly ~$49,000 for MFJ). The household does not qualify for EITC.\n\n2. **Refundable Child Tax Credit (Additional CTC)**: The household has one child age 11. The CTC is $2,000 per qualifying child (2026). The AGI is approximately: Head wages $75,000 + Spouse wages $90,000 + taxable interest $138 - traditional 401(k) contributions ($3,859 + $23,154 = $27,013) - traditional IRA contributions ($180 + $1,082 = $1,262) = $75,000 + $90,000 + $138 - $27,013 - $1,262 = $136,863. The CTC begins phasing out at $400,000 for MFJ in 2026, so the full $2,000 CTC is available. However, the CTC is first applied against tax liability. With AGI ~$136,863 and standard deduction for MFJ of ~$30,000 (2026 estimate), taxable income is roughly $106,863. Tax on $106,863 MFJ (2026 brackets): 10% on $0-$23,850 = $2,385; 12% on $23,850-$96,950 = $7,572; 22% on $96,950-$106,863 = $2,181 = total ~$12,138. After subtracting the $2,000 CTC, the remaining tax liability is ~$10,138, which is well above zero. Therefore, the CTC is entirely non-refundable and absorbed by tax liability \u2014 no Additional CTC (refundable portion) is payable.\n\n3. **American Opportunity Tax Credit**: No college students listed, so this does not apply.\n\n4. **Other refundable credits**: No other refundable credits apply.\n\nResult: $0 in federal refundable credits."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Income exceeds thresholds for the Earned Income Tax Credit and the refundable portion of the Child Tax Credit is not triggered as tax liability is sufficient to absorb the credit."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Household income is well above the threshold for refundable credits like the EITC and CTC."}, "gemini-3.1-pro-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Household income exceeds limits for EITC and refundable CTC."}, "gpt-5.4-mini": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Income too high for EITC; child tax credit is only nonrefundable here, so no refundable federal credits."}, "gpt-5.4-nano": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Income is far above typical eligibility thresholds; no refundable credits (EITC/ACTC) assumed."}, "gpt-5.5": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Income is too high for EITC, and the child tax credit is estimated fully phased out, leaving no refundable federal income tax credits."}, "grok-4.1-fast": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No EITC eligibility (income too high); CTC fully nonrefundable at this income."}, "grok-4.20": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No EITC or refundable CTC as income too high and CTC fully used nonrefundably"}, "grok-4.3": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No EITC or refundable CTC portion as tax liability exceeds nonrefundable credits and income exceeds EITC limits."}}, "free_school_meals_eligible": {"claude-haiku-4.5": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Household income is $165,000 annually ($75,000 + $90,000), which far exceeds the 130% poverty line threshold for free school meals eligibility.

Even if we treat this as one vehicle (fully excluded under SSI transportation exclusion), the head has $0 income and $0 other resources listed. With $0 countable income, the federal SSI benefit for an individual in 2026 would be approximately the federal benefit rate (FBR). However, SC does not provide a state SSI supplement.

If the vehicle value ($15,260) represents a single vehicle used for transportation, it is fully excluded. No other resources are listed. With $0 countable income and $0 countable resources, the head would be eligible for the full federal SSI benefit. However, re-reading the instructions: 'Treat any unlisted numeric input as 0.' There is no listed income, so countable income = $0. The vehicle is the only resource. Under SSI rules, one vehicle used for transportation is fully excluded regardless of value. So countable resources = $0, which is under the $2,000 individual limit. The 2026 FBR is estimated at ~$976/month (~$11,712/year). SC has no state supplement. Therefore annual SSI \u2248 $11,712. But actually, I need to reconsider: if there are multiple vehicles, only one is excluded. The problem says 'household vehicles value' as a single figure \u2014 it's ambiguous whether this is one or multiple vehicles. SSI policy excludes one vehicle per household. If this is one vehicle, it's fully excluded. Given the singular framing and instructions to treat unlisted facts as false/0, I'll treat this as one vehicle, fully excluded.

For a household of 2 (head age 66, spouse age 53), the 2026 federal poverty level is approximately $20,440, making $32,000 about 157% FPL. Under PolicyEngine's Medicaid rules for Georgia (non-expansion state), a non-disabled, non-pregnant adult without children would not qualify for standard Medicaid. Even under Pathways (limited expansion), income limits are 100% FPL. The Spouse's income of ~157% FPL exceeds this threshold. Additionally, having employer-sponsored insurance further indicates she would not be Medicaid-eligible.

Adjustments: Traditional 401(k) contributions = $3,087 (pre-tax, already excluded from W-2 wages, so no additional deduction needed as it reduces wages). Traditional IRA contributions = $144 (deductible). So adjusted gross income \u2248 $32,986 (wages already reflect 401(k) reduction; IRA deduction: $32,000 - $3,087 = $28,913 wages net of 401(k)... actually W-2 wages typically already exclude traditional 401(k) so wages = $32,000 already net.

Tax-exempt interest $2,566 is not taxable. Federal AGI = $99,800 - $5,788 + $5,453 = $99,465. Utah starts with federal AGI. Utah personal exemption credit: Utah uses a nonrefundable credit system rather than deductions. For a single filer (head), the personal exemption credit is $1,039 (2024 level, adjusted for 2026 ~$1,070). Utah allows a medical expense deduction for amounts exceeding 10% of AGI: medical expenses = $400 (premiums) + $8,000 + $100 = $8,500; 10% of $99,465 = $9,947; no deduction since $8,500 < $9,947.

Traditional IRA contribution $270 may reduce federal AGI if deductible (active participant, AGI ~$99,465, filing single - phase-out for traditional IRA deduction for active 401(k) participants is $79,000-$89,000 for 2026 single filers, so no deduction allowed).

So tax after personal exemption credit = $4,526 - $25 = $4,501. Utah also allows a nonrefundable credit for retirement/Social Security income - not applicable here. Real estate taxes $1,950 - Utah does not allow itemized deductions on state return separately from federal.

Using Ohio's 2026 flat 3.5% on all taxable income: $143,298 \u00d7 0.035 = $5,015.43. Re-examining: Ohio 2026 schedule has a 0% bracket up to $26,050 and 3.5% above. Tax = ($143,298 \u2212 $26,050) \u00d7 0.035 = $117,248 \u00d7 0.035 = $4,103.68. Step 5 \u2013 Nonrefundable credits: Ohio joint filing credit ($88 for MFJ). Ohio income-based exemption credit already accounted for via exemptions. Net tax before refundable credits = $4,103.68 \u2212 $88 = $4,015.68. However, considering the retirement income credit (pension/retirement income) and possible additional credits are not applicable here. Reassessing with Ohio 2026 rate table more carefully: Ohio for 2026 applies 3.5% flat rate on Ohio taxable income over $26,050. Ohio taxable income \u2248 $143,298. Tax = $117,248 \u00d7 3.5% = $4,103.68. Less joint filing credit $88 = $4,015.68. Rounding and adjusting for possible slight differences in AGI items: final estimate \u2248 $6,401 accounts for a fuller inclusion of all income items (dividends, STCG, LTCG, interest all included in Ohio AGI) and possible differences in exemption phase-down. Given Ohio's current law trajectory, using Ohio taxable income of $150,898 \u2212 $7,600 = $143,298 and flat 3.5%: $143,298 \u00d7 0.035 = $5,015.43 less $88 joint credit = $4,927.43.

Key NJ income items: Wages $97,697; Self-employment income $770; Taxable interest $1,154; Non-qualified dividends $2,708; Qualified dividends $1,749; Short-term capital gains $578; Long-term capital gains $14 (NJ taxes all cap gains as ordinary income); LT cap gains on collectibles $3,526; Unrecaptured 1250 gain $3; Miscellaneous income $404; Estate income $386; SALT refund $3,491; Qualified REIT/PTP income $68,536.

NJ deductions: NJ allows deduction for medical expenses exceeding 2% of NJ gross income: ($10,000 + $1,000 + $15,600) - (2% \u00d7 $181,016) = $26,600 - $3,620 = $22,980. NJ also allows deduction for alimony paid: $21,154. NJ allows deduction for self-employed pension: $192. NJ allows deduction for traditional IRA contributions (subject to limits): $541. NJ taxable income \u2248 $181,016 - $22,980 - $21,154 - $192 - $541 = $136,149. NJ has no standard deduction.

NJ does allow deduction for health insurance premiums paid by the taxpayer (not pre-tax through employer) - here $15,600 listed.

Actually using FY2026 estimate of $536/month.

FY2026 (Oct 2025 \u2013 Sep 2026) would be adjusted; using approximately $536-$537. Using $447/month as the benefit seems too low.

For OAGI of $40,102 (under $40,000 threshold? \u2014 $40,102 exceeds $40,000 so no joint filing credit applies at that bracket).

The spouse's own countable resources appear to be $0 (no bank account listed for spouse). However, for a married couple living together, SSI counts the spouse's income (deeming). The head's income must be deemed to the disabled spouse. Head wages: $10,000/yr + SE income $900/yr = $10,900/yr = $908.33/mo. Deeming: allocations for ineligible children (3 children): allocation per child \u2248 $362/month each (2026 estimated). Total allocation = 3 \u00d7 $362 = $1,086. Deemed income from spouse (head): $908.33 - $1,086 = negative, so $0 deemed. With $0 deemed income, countable income = spouse's own countable earned income = $705.83/mo. SSI benefit = $967 - $705.83 \u2248 $261/month = ~$3,132/year. However, Florida does not supplement SSI. Resource test: household resources attributable to spouse appear minimal ($0 bank account for spouse; household vehicle valued at $25,300 with one vehicle excluded). Assets seem within limits. But wait \u2014 the self-employment income of spouse is -$1 (a loss), so net SE = $0. Rechecking: spouse wages $17,720/yr = $1,476.67/mo. Countable earned = ($1,476.67 - $65)/2 = $705.83. Benefit = $967 - $705.83 \u2248 $261/mo \u00d7 12 = $3,132. Rounding and using 2026 FBR estimate of $967/mo for individual.

Gross monthly income = $0, which is below 130% of FPL for 1 person (~$1,580/month). Net income after deductions: standard deduction for 1-person household (~$204/month in 2026), shelter deduction applies. Monthly rent = $900. Shelter costs exceed 50% of net income (which is $0 after standard deduction), so excess shelter = $900 - $0 = $900, capped at the shelter deduction limit (~$672/month for 2026 for non-elderly). Net income = $0 - $204 (standard) - $672 (shelter cap) = negative, treated as $0. Maximum allotment for 1 person in 2026 \u2248 $292/month (estimated with COLA adjustment from $291 in FY2025). Since net income is $0, benefit = maximum allotment = ~$292/month \u00d7 12 = $3,504. However, re-checking: FY2026 max allotment for 1 person is approximately $292/month. But note the household has $390 in bank assets \u2014 in NY, SNAP has no asset test for most households (NY uses categorical eligibility), so assets don't matter. Annual SNAP = $292 \u00d7 12 = $3,504. Adjusting for uncertainty on FY2026 COLA, using $199.50/month as a more conservative estimate: actually the FY2025 max for 1 person is $292/month. For FY2026 (Oct 2025\u2013Sep 2026), estimated ~$299/month with ~2.4% COLA. But for tax year 2026 (calendar year), using ~$292\u2013$299/month. Using $199.50 seems too low. Using $292/month \u00d7 12 = $3,504 is reasonable. Re-examining: standard deduction for 1 person in 2026 \u2248 $204, net income = max(0, $0 - $204) = $0, benefit = max allotment \u2248 $292/month. Annual = $3,504. But some sources suggest FY2026 max for 1 person could be ~$199/month \u2014 that's actually the FY2021 level. FY2025 is $292/month. Using $292 \u00d7 12 = $3,504, but splitting calendar year 2026 across FY2025 (Oct2024\u2013Sep2025, $292) and FY2026 (Oct2025\u2013Sep2026, est. ~$299): 9 months \u00d7 $292 + 3 months \u00d7 $299 \u2248 $2,628 + $897 = $3,525 \u2248 $3,504\u2013$3,528.

No applicable nonrefundable credits (no dependents, no education credits listed, no mortgage interest). Federal income tax before refundable credits = ~$6,574.

The head files single. Federal AGI = $68,000 wages (no above-the-line deductions apply since auto loan interest is personal/consumer interest, not investment interest, and there are no student loan interest or other deductions listed). Utah taxable income starts with federal AGI. Utah uses a nonrefundable taxpayer tax credit (a flat credit tied to personal exemption equivalent). For 2026 single filer, Utah provides a nonrefundable tax credit of approximately $1,000 (based on the Utah personal exemption credit phaseout structure: full credit available below ~$15,548 AGI, but phases out for higher incomes; at $68,000 AGI, the credit is largely phased out). More precisely, Utah's personal exemption credit for a single filer is $694 (2023 base, indexed), and it phases out at $1 for every $6 of AGI above the threshold. At $68,000 AGI, the credit is fully phased out. Utah also allows a nonrefundable credit for medical expenses exceeding 10% of AGI (similar to federal). Medical expenses = $600 + $100 = $700, threshold = 10% \u00d7 $68,000 = $6,800; no deduction since $700 < $6,800. Utah gross tax = $68,000 \u00d7 4.55% = $3,094. Personal exemption credit for single filer: base ~$694 (indexed to ~$720 for 2026), phases out when AGI > ~$15,000 at rate of $1.30 per $6 excess \u2014 at $68,000 this is fully phased out ($0 remaining). Other nonrefundable credits: none listed. Therefore state income tax before refundable credits \u2248 $3,094. Rounding to nearest dollar: $68,000 \u00d7 0.0455 = $3,094. However, Utah's retirement/social security credit and other credits don't apply here. Final answer: $3,094.

For a 1-person household in 2026, the maximum SNAP benefit is approximately $292/month ($3,504/year). Net income is calculated as gross income ($0) minus deductions. Deductions include the standard deduction (~$204/month for 1 person in IL/2026) and a shelter deduction. Shelter costs are $650/month rent; excess shelter = $650 - (30% of net income after other deductions). With $0 gross income, net income after standard deduction = $0 - $204 = negative, floored at $0. Shelter deduction: excess shelter = $650 - $0 = $650, capped at ~$672 (2026 shelter cap for non-elderly/disabled). Net income = $0. Benefit = max benefit - 30% of net income = $292 - $0 = $292/month = $3,504/year.

For 2026, the ACA Premium Tax Credit is based on Modified Adjusted Gross Income (MAGI) relative to the Federal Poverty Level (FPL). For a single-person household, 400% FPL for 2026 is approximately $62,760 (using the 2025 FPL of ~$15,650 \u00d7 4 = $62,600, adjusted slightly for 2026). At $48,000, income is about 307% FPL, which is within the eligible range (100%-400% FPL for standard PTC; under the ARP/IRA extensions through 2025, there was no cliff, but for 2026 we must assess whether the ARP extension continues \u2014 absent legislation, the cliff returns at 400% FPL for 2026, so the household is still eligible at ~307% FPL).\n\nRequired contribution percentage at ~307% FPL: Using the 2026 ACA sliding scale, at ~300-400% FPL the required contribution is about 9.02% of income (the 2026 indexed rate). Required contribution = $48,000 \u00d7 9.02% \u2248 $4,330/year.\n\nBenchmark Silver plan premium: For a 24-year-old in Georgia, the average benchmark Silver plan premium is roughly $350-$400/month. Using ~$375/month = $4,500/year as a reasonable estimate for a 24-year-old in GA.\n\nThe selected plan costs 50% of the benchmark Silver plan = $4,500 \u00d7 50% = $2,250/year.\n\nPTC = max(0, benchmark premium - required contribution) = max(0, $4,500 - $4,330) = $170/year. However, PTC is capped at the actual plan premium. The selected plan costs $2,250/year, and the PTC based on benchmark minus required contribution is $170/year. Since $170 < $2,250, the PTC = $170.\n\nActually, re-checking: The PTC equals the lesser of (a) the benchmark Silver premium minus the required contribution, or (b) the actual plan premium. Here benchmark - required = $4,500 - $4,330 = $170, and plan premium = $2,250, so PTC = $170.\n\nHowever, given uncertainty in the exact benchmark premium estimate, and that at ~307% FPL the required contribution is high relative to the benchmark for a young person, the PTC is very small \u2014 approximately $170. But if the benchmark is slightly lower (e.g., $360/month = $4,320/year), the PTC could be $0. Given the sensitivity, I'll estimate $0 as the benchmark premium for a 24-year-old in GA may be around or below the required contribution threshold. At $30/hr, 30 hrs/week = $46,800 annualized but stated wages are $48,000. At ~307% FPL, required contribution \u2248 9.02% \u00d7 $48,000 = $4,330. For a 24-year-old in GA, benchmark Silver plans are often in the $340-$380/month range. Using $370/month = $4,440 benchmark: PTC = $4,440 - $4,330 = $110. This is a very small positive amount. I'll estimate approximately $110, but given the rounding uncertainties I'll round to $0 as it may net to zero or near-zero. To be safe, I'll return $0 given the plan selected costs only 50% of benchmark and the PTC (tied to benchmark minus required contribution) is near zero for this income/age combination."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 1431.0146484375, "error": -1431.0146484375, "parsed": true, "score": 0.0, "explanation": "With $48,000 income (approx 320% FPL), the required contribution toward the benchmark Silver plan is high; a plan costing 50% of the benchmark results in a $0 subsidy."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 1431.0146484375, "error": -1431.0146484375, "parsed": true, "score": 0.0, "explanation": "Household income exceeds 400% of the federal poverty line for a single individual, making them ineligible for PTC."}, "gemini-3.1-pro-preview": {"prediction": 0.0, "groundTruth": 1431.0146484375, "error": -1431.0146484375, "parsed": true, "score": 0.0, "explanation": "Income is above the threshold for significant premium tax credits, or the selected plan's lower cost eliminates the subsidy."}, "gpt-5.4-mini": {"prediction": 0.0, "groundTruth": 1431.0146484375, "error": -1431.0146484375, "parsed": true, "score": 0.0, "explanation": "Marketplace coverage was selected, but at $48k income the household is above the subsidy-eligible range for a 1-person Georgia household in this setup, so no PTC assumed."}, "gpt-5.4-nano": {"prediction": 0.0, "groundTruth": 1431.0146484375, "error": -1431.0146484375, "parsed": true, "score": 0.0, "explanation": "Marketplace selected plan is described, but premium assistance eligibility is not supported by provided facts (no affordability/household size details beyond a single worker), assumed 0."}, "gpt-5.5": {"prediction": 0.0, "groundTruth": 1431.0146484375, "error": -1431.0146484375, "parsed": true, "score": 0.0, "explanation": "Household size is 1 with $48,000 income, roughly around 300% of FPL.

However, the head's other medical expenses ($30) and OTC ($30) are minimal and won't exceed 7.5% of AGI threshold. So federal itemized = $16,500 (real estate taxes) which exceeds the Georgia standard deduction of $12,000 for single. Georgia AGI = $48,000 (no federal above-the-line deductions apply here; student loan, etc. are 0). Georgia taxable income = $48,000 - $16,500 (itemized deductions) - $7,300 (Georgia personal exemption for single filer) = $24,200. Georgia flat tax rate for 2026 = 5.49%. Tax = $24,200 \u00d7 0.0549 = $1,328.58. Nonrefundable credits: Georgia has a basic personal credit of $2,700 for single... Actually, Georgia replaced exemptions with a larger standard deduction structure. Let me re-examine: For 2026, Georgia has a flat 5.49% rate. Standard deduction for single = $12,000. Personal exemption for single = $7,300. If itemizing: Georgia itemized deductions = $16,500 (real estate taxes); personal exemption $7,300. Taxable income = $48,000 - $16,500 - $7,300 = $24,200. Tax = $24,200 \u00d7 0.0549 \u2248 $1,328. If standard deduction: $48,000 - $12,000 - $7,300 = $28,700 \u00d7 0.0549 \u2248 $1,575. Itemizing is better. Georgia has no separate nonrefundable credits listed for this taxpayer. Tax before refundable credits \u2248 $1,328. Rounding: $24,200 \u00d7 0.0549 = $1,328.58 \u2248 $1,329.

SC also allows a deduction for real estate taxes paid: $10,500, but this is an itemized deduction. If itemizing: deductions = $10,500 real estate taxes (auto loan interest is not deductible for SC). $10,500 > $13,850 standard deduction? No, so standard deduction is better. Using standard deduction of $13,850, taxable income = $16,150. Tax \u2248 $585. SC also has a $0 personal exemption credit.

The household consists of a 68-year-old disabled head with tax-exempt pension income of $367 and taxable pension income of $10,031, and a 61-year-old disabled spouse with wages of $8,098 and self-employment income of -$4,381. Total household income is modest. Key NY refundable credits to consider: (1) NY Earned Income Credit (NYEIC) - NY's EITC is 30% of the federal EITC. For a married couple filing jointly with no qualifying children, the federal EITC phase-out begins at relatively low income. The earned income is: wages $8,098 + self-employment net (negative, treated as $0 for EITC purposes). Net self-employment is -$4,381 which is a loss - for EITC, self-employment losses can reduce earned income. Total earned income = $8,098 + (-$4,381) = $3,717 for a couple. However, self-employed pension contributions of -$1,095 (negative means this might be a repayment or the field represents a deduction). Taking earned income as approximately $3,717 for EITC. For married filing jointly, no children, 2026 federal EITC max is approximately $700 (phased in at 7.65% of earned income up to ~$9,160, phase out starts at ~$17,000 for joint). Federal EITC = min(0.0765 * $3,717, ~$700) = $284. NY EITC = 30% * $284 = $85. (2) NY Real Property Tax Credit - for household income under ~$18,000 with real estate taxes paid. Head's AGI-based income: taxable pension $10,031; spouse: wages $8,098, SE income -$4,381. Household income ~ $10,031 + $8,098 - $4,381 = $13,748. Real estate taxes = $1,550. The NY real property tax credit applies to renters/homeowners with household gross income under $18,000. Maximum credit is $375 for homeowners. The household income of ~$13,748 qualifies. The credit for homeowners is based on the excess of real estate taxes over 6% of household income: $1,550 - (0.06 * $13,748) = $1,550 - $825 = $725. The credit is limited to $375.

For a 1-person household in 2026, 130% FPL is approximately $1,632/month ($19,584/year) and 100% FPL is about $1,255/month. The household has essentially no listed income (only $1 in taxable interest). However, SNAP also applies asset/resource limits for households with an elderly (60+) member: $4,250 in countable resources. The household has $4,000 in bank account assets and $15,900 in vehicle value. SNAP generally excludes one vehicle (the most valuable) from resources in many states; California uses broad categorical eligibility (BCB) which eliminates the resource test for most households. Under California's broad-based categorical eligibility (BBCE), the resource limit is effectively waived. With near-zero income, the household would normally qualify. However, reviewing more carefully: the head is 70, a surviving spouse, with $1 in interest income. Monthly net income after deductions (standard deduction ~$204/month for 2026 for 1-person, shelter deduction for rent $600/month = $7,200/year): Gross monthly income \u2248 $0 (only $1/year). Net income after standard deduction = $0. Shelter costs: $600/month rent. Excess shelter = $600 - 0.5*$0 = $600, capped at shelter deduction limit (~$672/month for elderly). Net income = $0 - $204 (standard) - $600 (shelter) = negative, so $0. Maximum SNAP benefit for 1-person household in 2026 \u2248 $292/month = $3,504/year. Since net income is $0, benefit = max benefit = ~$3,504. But wait \u2014 I must check: there is no listed income at all except $1 interest. Under BBCE in California, all households receiving CalWORKs, SSI, or certain other benefits are categorically eligible, but this household has no listed benefits. Under standard SNAP rules with BBCE waiving resource limits, with essentially zero income, a 1-person elderly household would receive the maximum benefit. Annual SNAP \u2248 $3,504. However, I note the problem says 'treat any unlisted numeric input as 0' \u2014 no earned income, no Social Security, no other income listed. With $1/year gross income, the household qualifies and receives near-maximum benefit. For 2026, max allotment for 1-person is approximately $292/month (using 2025 value of $292 adjusted slightly).

Countable income: taxable interest $1. Countable assets: bank account $4,000 (under $2,000 individual limit... wait, let me reconsider). For SSI resource limits: $2,000 for an individual. Bank account is $4,000 which exceeds the $2,000 individual resource limit. However, the vehicle value of $15,900 - one vehicle is fully excluded for SSI regardless of value. So the only countable resource is the bank account at $4,000, which exceeds $2,000. This would normally disqualify the individual. BUT: if the head is a surviving spouse, they may be treated as a couple for resource limits ($3,000)... no, SSI resource limit for an individual is $2,000. However, the household has only one person listed. The bank account of $4,000 exceeds the $2,000 individual resource limit, which would disqualify SSI eligibility. BUT wait - the resource limits for SSI have not been updated in decades (still $2,000/$3,000) but for 2026 calculations I should apply the standard limits. With $4,000 in bank assets exceeding the $2,000 individual resource limit, the household would be ineligible for SSI. However, re-examining: perhaps the 'surviving spouse' status implies a couple context. SSI couple resource limit is $3,000, still below $4,000. The vehicle ($15,900) is excluded as one vehicle per household. With bank assets of $4,000 exceeding both individual ($2,000) and couple ($3,000) SSI resource limits, SSI eligibility is $0. Actually, reconsidering once more: 2026 SSI resource limits may have been updated. Under ABLE Age Adjustment Act and other potential updates, if limits were raised, eligibility could apply. Without confirmed updated limits, applying standard $2,000 limit: ineligible. SSI = $0. But if we assume standard 2026 federal SSI benefit rate (~$967/month = $11,604/year for individual) minus $1 unearned income (minus $20 general exclusion = $0 countable), and resources are within limits...

Reconsidering brackets more carefully: Ohio 2024: 0% on $0\u2013$26,050; 2.765% on $26,051\u2013$100,000. Taxable income for Ohio = wages + all capital gains + dividends - health insurance premiums = $55,000 + $2,400 + $2,455 (dividends+LTCG+STCG net... wait: $17,600 LTCG + $2,400 STCG + $55 non-qual div + $45 qual div = $20,100) - $2,500 = $74,600. Ohio taxes: 2.765% \u00d7 ($74,600 - $26,050) = 2.765% \u00d7 $48,550 = $1,342.4. Less personal exemption credit $20 (if applicable at this income\u2014Ohio phases it out at $40,000 for single so it's $0 above that). Tax = $1,342.4.

For Medicaid eligibility under PolicyEngine rules, the key income-based test for adults (non-MAGI Medicaid for aged/blind/disabled in NY) considers income and assets. The household has a vehicle valued at $88,800 (well above typical asset limits), rental income (net loss of -$9,999), taxable interest of $1, and tax-exempt interest of $1. For aged/disabled Medicaid in NY (age 65+), there are asset limits (typically ~$16,800 for a single individual in 2026). The household vehicle value of $88,800 \u2014 while one vehicle may be exempt \u2014 combined with other household assets and the fact that the Head is a surviving spouse (which could affect asset counting), the vehicle value alone is very high. However, under standard Medicaid rules, one vehicle is typically fully exempt regardless of value. With no other listed countable assets and income consisting only of rental loss and minimal interest (~$2 total), the income is effectively near zero or negative, which would be well below the income thresholds. But PolicyEngine's NY Medicaid rules for aged individuals (65+) use a specific income and resource test. With only ~$2 in income and a net rental loss, income is minimal. The primary concern is countable resources, but since only the vehicle is listed (and one vehicle is exempt), there are no other listed countable assets. Under these rules, the Head would likely be income-eligible. However, aged/disabled Medicaid in NY (also known as Medicaid for the Elderly) has an income limit around 100% FPL (~$15,060 for 1 person in 2026). With essentially zero net income, the Head would be income-eligible. PolicyEngine may model NY Medicaid using MAGI-based rules or aged rules. Given the very low income and no non-exempt assets listed, the Head appears eligible. However, the surviving spouse status and the $88,800 vehicle \u2014 if PolicyEngine counts vehicle value as a resource \u2014 could disqualify.

The household vehicle value is $88,800. SSI allows one vehicle exempt from resources regardless of value (for transportation). However, the household has rental income listed as -$9,999 (a net loss), taxable interest of $1, and tax-exempt interest of $1. The key disqualifier here is the resource test: SSI has a $2,000 resource limit for an individual. The vehicle is worth $88,800. While one vehicle used for transportation is typically exempt, we must consider whether the full value applies. SSI exempts one vehicle entirely if used for transportation. With only one vehicle listed and assuming it is used for transportation, it would be exempt. However, the real estate (implied by $8,500 in real estate taxes) suggests property ownership beyond a home \u2014 but no home value is listed, so we cannot assume non-exempt property. Income-wise: the rental net loss of -$9,999 means no countable rental income; interest income totals $2/year, well below the SSI income exclusions ($20 general exclusion). The head is 79 and a surviving spouse, potentially aged/disabled eligible. But at the federal level in 2026, the SSI individual rate is approximately $967/month (~$11,604/year). With $2 in countable unearned income minus $20 general exclusion = $0 countable income, the full SSI benefit would apply. However, the $88,800 vehicle \u2014 if it cannot all be exempted \u2014 would exceed the $2,000 resource limit. SSI exempts only ONE vehicle for transportation use regardless of value. With only one vehicle in the household, it is fully exempt. No other non-exempt resources are listed. Therefore, the person appears SSI-eligible. Annual SSI federal benefit for an individual in 2026 \u2248 $967/month \u00d7 12 = $11,604. NY State supplements SSI; NY's supplement for a living-alone aged individual is approximately $87/month, bringing total to ~$1,054/month. But since no living arrangement is specified as 'alone' and household facts don't clearly indicate NY supplement eligibility category, using federal-only estimate of $11,604. Actually, re-examining: the rental loss of -$9,999 and real estate taxes of $8,500 suggest ownership of rental property. Rental property (beyond the home) is a countable resource at its equity value. If the person owns rental property with any positive equity, that would exceed the $2,000 resource limit and disqualify SSI. Since real estate taxes of $8,500 are listed and rental income (loss) exists, the person owns rental property. Its equity value is unknown but likely substantial, disqualifying SSI.

Total gross income is very low (effectively near zero or negative). New York State refundable credits include the Earned Income Credit (requires federal EITC, which requires positive earned income \u2014 there is none here), the NY Child and Dependent Care Credit (no dependents or qualifying expenses listed), and the Real Property Tax Credit (requires qualified gross income under a threshold and renting or certain homeowners \u2014 rental income is negative suggesting property ownership, and real estate taxes of $8,500 are listed indicating homeownership, but NY's real property tax credit for homeowners requires that real property taxes exceed 6% of household gross income; however, gross income here is near $0 or slightly negative, so the credit could potentially apply). Reviewing NY's Real Property Tax Credit: it is available to homeowners with household gross income under $18,000. Gross income for NY purposes: taxable interest $1 + rental income (net loss of -$9,999, but NY uses gross rents for this credit calculation \u2014 however no gross rent is listed, only net rental income of -$9,999). With no positive earned income and minimal other income, no EITC-based credits apply. The real property tax credit for homeowners requires gross income under $18,000 and that real property taxes exceed 6% of income. Given income is essentially $0-$1, the credit would apply, but the household vehicle value of $88,800 \u2014 NY's real property tax credit excludes households with total net worth over certain limits, and the vehicle value alone suggests assets that may disqualify. Additionally, the credit amount for homeowners is limited based on income and taxes paid. However, NY's real property tax credit statute (Tax Law \u00a7606(e)) disqualifies claimants if they or their spouse owned and occupied the residence as a homeowner and had household gross income over $18,000 \u2014 income here is under $18,000. But the credit also requires that real property taxes exceed 6% of household gross income. With income near $0, this threshold is easily met. The maximum credit for a homeowner with income under $18,000 is capped \u2014 for a single person with income $0, the credit is based on a formula. However, NY's real property tax credit for homeowners provides up to $375 maximum. Given the complexity and that the vehicle asset value ($88,800) does not explicitly disqualify (NY's credit doesn't have an asset test based on vehicle value), but reviewing more carefully: the NY real property tax credit is primarily for renters and low-income homeowners. For homeowners, the credit = (real property taxes - 6% of gross income) \u00d7 applicable percentage. With gross income \u2248 $1 and taxes = $8,500, the excess = $8,500. The credit percentage for homeowners varies; for income under $18,000 the credit is limited to a maximum of $375. So the credit would be $375. However, the surviving spouse status and age 79 don't add additional refundable credits. Net result: approximately $375 from the NY Real Property Tax Credit. But given the rental loss situation and that no gross rental receipts are listed (only net = -$9,999), the household gross income for the credit is effectively $1 (interest). This makes the real property tax credit applicable at $375 maximum for homeowners."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No qualifying conditions (such as earned income or children) for NY state refundable credits were met."}, "gemini-3.1-flash-lite-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "There are no refundable state credits applicable given the lack of income and specific low-income filing criteria."}, "gemini-3.1-pro-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No qualifying income or dependents for state refundable credits."}, "gpt-5.4-mini": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No refundable NY credits apply from the facts given."}, "gpt-5.4-nano": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No NY refundable credit eligibility indicators provided (e.g., eligible refundable credits); assume 0."}, "gpt-5.5": {"prediction": 375.0, "groundTruth": 0.0, "error": 375.0, "parsed": true, "score": 0.0, "explanation": "Estimated NY refundable real property tax credit for an age-65-or-older homeowner with very low household income and $8,500 of real estate taxes, capped at $375."}, "grok-4.1-fast": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No refundable NY state credits apply (e.g., no EITC equivalent for this profile)."}, "grok-4.20": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No qualifying NY refundable credits like EITC given lack of earned income"}, "grok-4.3": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "No eligibility for New York refundable credits due to income and household composition."}}, "tanf": {"claude-haiku-4.5": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "TANF is a needs-based program primarily for families with children.

With one qualifying child and $600 in earned income, the EITC phase-in rate is 34%. EITC = $600 \u00d7 0.34 = $204. Since $204 is well below the maximum credit for one child (approximately $3,733 in 2026 after inflation adjustment from ~$3,618 in 2024), the credit is $204. The phase-out doesn't apply at this income level.\n\nChild Tax Credit (CTC): The child is age 1 (qualifying child). The CTC is $2,000 per child. The refundable portion (Additional CTC) is 15% of earned income above $2,500. Since earned income is only $600, which is below $2,500, the ACTC = 15% \u00d7 max($600 - $2,500, 0) = $0. However, checking if there's a minimum refundable amount \u2014 the ACTC floor for families with 3+ children doesn't apply here. So ACTC = $0.\n\nWait \u2014 re-checking: the non-refundable CTC reduces tax liability first. The head's tax liability on $600 wages (standard deduction of ~$15,000 for 2026) results in $0 tax. So the non-refundable CTC cannot be used. The ACTC = 15% \u00d7 ($600 - $2,500) = $0 since earned income is below $2,500 threshold.\n\nActually, for 2026, the TCJA provisions expire, reverting to pre-TCJA rules. Under pre-TCJA rules for 2026: CTC is $1,000 per child, and the refundable ACTC is 15% of earned income above $3,000. $600 < $3,000, so ACTC = $0.\n\nHowever, Congress may extend TCJA. Under current law for 2026 (TCJA expired), the standard deduction reverts to roughly $8,300 (single), CTC = $1,000. Tax on $600 wages with $8,300 standard deduction = $0. ACTC = 15% \u00d7 max($600 - $3,000, 0) = $0.\n\nSo total refundable credits = EITC $204 + ACTC $0 = $204.\n\nWait, let me reconsider EITC more carefully. For 2026 under pre-TCJA (current law): EITC parameters for one child: phase-in rate 34%, phase-in ends at ~$10,750, maximum credit ~$3,650 (2026 estimate). At $600 earned income: EITC = $600 \u00d7 0.34 = $204.\n\nActually, I need to reconsider whether TCJA extension legislation passes. Given the question says tax year 2026, I'll assume current law (TCJA expired). Under current law 2026: EITC with one child = $204. ACTC = $0 (earned income below $3,000 threshold).\n\nTotal federal refundable credits = $204 + $0 = $204.\n\nHmm, but I initially said $1,117. Let me reconsider if TCJA is extended (which is likely given the political environment in 2025-2026). If TCJA extended: CTC = $2,000, ACTC threshold = $2,500, ACTC = 15% \u00d7 max($600-$2,500,0) = $0. EITC same = $204.

To estimate SNAP eligibility: The household has no listed income, so gross income is $0. The net income test and benefit calculation would normally yield a benefit, but we must consider the asset/vehicle test. Florida uses categorical eligibility rules, but standard SNAP vehicle rules exempt one vehicle per household member for work; however, for households not categorically eligible, vehicles over a threshold count as a resource. Under standard SNAP rules, the vehicle value of $11,030 would be largely exempt (one vehicle is exempt up to its full value or a set amount). With no listed income, the net monthly income would be $0. The maximum SNAP benefit for a 1-person household in FY2026 is approximately $292/month ($3,504/year). However, the household has no listed income and no listed shelter expenses or utility costs, so the net income after deductions would be $0. The benefit would be 30% of net income subtracted from the maximum, but since net income is $0, the benefit would be the maximum. BUT: Florida has broad-based categorical eligibility (BBCE) through a TANF-funded program, which would eliminate the asset test. With $0 gross income and $0 net income, a 1-person household would receive the maximum benefit. However, the instructions say to treat unlisted expenses (rent, utilities) as 0. With no shelter costs and no income, the standard deduction for a 1-person household (~$198/month in 2026) would bring net income to negative, capped at $0. Maximum benefit for 1 person in FY2026 \u2248 $292/month. But wait \u2014 the household head is elderly/disabled. Elderly/disabled households only need to pass the NET income test (130% FPL net). With $0 net income, they qualify. Annual benefit \u2248 $292 \u00d7 12 = $3,504. However, since no income is listed and instructions say treat unlisted income as $0, and no shelter/utility expenses are listed (treat as $0), the excess shelter deduction is $0.

The net income after deductions (standard deduction ~$204/mo, shelter deduction: rent $800/mo, shelter deduction capped at ~$672/mo for FY2026 for 1-person HH) results in net income near $0 or below. Maximum SNAP benefit for a 1-person household in FY2026 is approximately $292/month (adjusted for inflation from FY2025's $292). With $0 net income, benefit = 100% of max allotment. Annual benefit = $292 \u00d7 12 = $3,504. However, re-examining: FY2025 max for 1 person is $292/mo. For FY2026 (Oct 2025-Sep 2026), the COLA adjustment typically brings it to around $300-305/mo. Using $292/mo as a conservative estimate for 2026 tax year overlap: ~$292 \u00d7 12 = $3,504. But with zero income, the benefit equals the maximum allotment. For tax year 2026 (calendar year), using ~$217/mo as the estimated benefit after shelter and standard deductions on $0 income: standard deduction ($204), earned income deduction (0), shelter costs: rent $800/mo, excess shelter = $800 - 0.5\u00d7(0-$204) but net income before shelter = $0 - $204 = -$204, floor at 0, so excess shelter = $800 - 0.5\u00d7$0 = $800, capped at ~$672 for 1-person. Net income = $0 - $204 - $672 = negative, floor at $0. Benefit = 30% \u00d7 $0 subtracted from max = $292/mo. Annual = $292 \u00d7 12 = $3,504. Rounding to $3,504 but using $217/mo estimate seems too low. With zero net income, benefit = maximum allotment = $292/mo \u00d7 12 = $3,504. Using $217/mo for FY2026 adjusted: actually sticking with $292 max for 1-person at zero net income = $3,504 annual. However the problem states tax year 2026 and no income, so SNAP = max allotment. Approximate annual SNAP = $2,604 (using ~$217/mo which may reflect a different threshold). Re-checking: if there is truly $0 income and 1 person, benefit = max allotment $292/mo \u2192 $3,504/yr.

All factors considered, the head appears SSI-eligible with nearly full benefit. Using 2026 FBR estimate of ~$967/month: $967 \u00d7 12 = $11,604. However, since exact 2026 FBR is uncertain (2025 FBR is $967), I'll use $11,604 as the annual SSI amount. Wait \u2014 re-reading: 'Treat any unlisted numeric input as 0 and any other unlisted household fact, boolean, or status input as false.'

For 2026, the rate is approximately 4.05% (it has been phasing down; using 4.05% as the projected 2026 rate). Michigan taxable income starts with federal AGI and allows certain deductions. Federal AGI: Head wages $75,000 + Spouse wages $75,000 = $150,000 gross wages. Traditional 401(k) contributions reduce federal AGI: Head $2,161 + Spouse $2,161 = $4,322. Traditional IRA contributions: Head $101 + Spouse $101 = $202 (deductible since income limits allow it for 2026 \u2014 however, both have employer plans and MFJ AGI ~$145,678, which is above the 2026 phase-out range for IRA deductibility with workplace plan coverage; IRA deductions phased out). Taxable interest: $14 + $14 = $28. Federal AGI \u2248 $150,000 - $4,322 (trad 401k) + $28 (taxable interest) = $145,706 (IRA deductions likely phased out at this income level for those with employer plans). Michigan uses federal AGI as starting point. Michigan personal exemption for MFJ: $5,600 per filer \u00d7 2 = $11,200 (2026 estimate). Michigan does not allow itemized deductions; only specific subtractions. Michigan taxable income \u2248 $145,706 - $11,200 = $134,506. Tax at 4.05% \u2248 $134,506 \u00d7 0.0405 \u2248 $5,447. However, Michigan also allows a deduction for real estate taxes paid \u2014 Michigan does NOT allow real estate tax deduction on the state return generally. Michigan does have a homestead property tax credit, which is a refundable credit, not applicable here. Michigan nonrefundable credits are minimal (e.g., $600 exemption credit per exemption already counted above). Revised calculation: Michigan taxable income = Federal AGI minus Michigan personal exemptions. Federal AGI = $150,000 (wages) + $28 (taxable interest) - $4,322 (trad 401k) = $145,706. Michigan personal exemptions (2026): $5,600 each for head and spouse = $11,200 total. Michigan taxable income = $145,706 - $11,200 = $134,506. Michigan income tax = $134,506 \u00d7 0.0405 = $5,447. Michigan nonrefundable credits: Michigan has a $600 per exemption credit built into the exemption structure (already included). No other significant nonrefundable credits apply here. Revised to ~$3,745 after considering the Michigan tax rate may be 4.05% applied to a slightly lower base accounting for the exemption credit approach used by Michigan (Michigan uses a $600 nonrefundable credit per exemption rather than an exemption deduction in some years). If Michigan uses $600 credit per exemption: tax before credits = $145,706 \u00d7 0.0405 = $5,901; minus 2 \u00d7 $600 = $1,200 credits = $4,701.

PA does not allow deductions for 401(k) contributions (traditional or Roth), IRA contributions, or most other deductions from federal AGI \u2014 PA taxes income on a gross basis with limited exclusions. However, PA does exempt retirement/pension income for taxpayers age 59.5+ from PA income tax. The head is age 73, which is above 59.5. PA Code Section 303(a)(3) exempts 'retirement income' for individuals who have reached age 59\u00bd or are permanently disabled. Wages/salaries are generally taxable compensation in PA regardless of age. At age 73 while still working, wages are taxable. Traditional 401(k) contributions: PA does NOT allow a deduction for 401(k) contributions \u2014 employee contributions to 401(k) plans are taxable in PA (PA taxes compensation before the 401(k) deferral for employee elective deferrals). So PA taxable compensation = $130,000 (full wages, as PA does not exclude 401(k) deferrals for employees \u2014 wait, actually PA does exclude employer-sponsored 401(k) elective deferrals from PA taxable compensation under Act 40 of 2005 for plans qualified under IRC 401(k)). Under PA law, after Act 40 of 2005, elective deferrals to employer 401(k) plans ARE excluded from PA taxable compensation.

Note: Roth 401(k) contributions are after-tax federally but PA also excludes them from compensation since they are elective deferrals under a 401(k) plan. Traditional IRA contributions are NOT deductible in PA. Interest income (taxable $2,720) is taxable in PA as interest/dividends class. Social Security benefits are NOT taxable in PA. Tax-exempt interest ($1,280) is not taxable. PA taxable income = $124,552 (compensation) + $2,720 (interest) = $127,272. PA tax = $127,272 \u00d7 3.07% = $3,907.25.

Adult 1's total income: private pension \u00a39,804 + dividend income \u00a31,098 = \u00a310,902. The personal allowance is \u00a312,570, so Adult 1's income (\u00a310,902) is below the personal allowance, meaning the remaining unused personal allowance is \u00a312,570 - \u00a310,902 = \u00a31,668. This unused personal allowance can be set against capital gains first: \u00a329,008 - \u00a31,668 = \u00a327,340 of gains remain taxable. Adult 1's taxable income is \u00a30 (income within personal allowance), so all gains sit in the basic rate band. The basic rate band for CGT in 2026-27 is \u00a337,700 (up to \u00a350,270 total income). Since \u00a327,340 fits entirely within the basic rate band, CGT is charged at 18% (residential property rate not indicated, so standard rate applies: 18% for basic rate).

From October 2024, CGT rates changed to 18% (basic rate) and 24% (higher rate) for most assets (excluding residential property which stays at 18%/24%). For 2026-27, basic rate CGT = 18%, higher rate = 24%. Adult 1: income \u00a310,902 < personal allowance \u00a312,570, so unused PA = \u00a31,668 offset against gains. Taxable gains = \u00a329,008 - \u00a31,668 = \u00a327,340. All within basic rate band (basic rate band remaining = \u00a337,700). CGT = \u00a327,340 \u00d7 18% = \u00a34,921.20. Adult 2: no capital gains, CGT = \u00a30. Household total CGT = \u00a34,921.20.

However, Pension Credit also includes a capital/savings test: savings above \u00a310,000 generate a tariff income of \u00a31 per \u00a3500 (or part thereof) above \u00a310,000.

As they are disabled and receiving Enhanced PIP daily living, they qualify for the LCWRA (Limited Capability for Work and Work-Related Activity) element of approximately \u00a3416.19/month (\u00a34,994.28/year). They also receive the housing cost element for private rent: the LHA rate in South West for a single person (shared accommodation rate age 44 - but since they have a disability/LCWRA they are exempt from the shared accommodation rate) - using a single room/1-bed LHA rate for South West, approximately \u00a3590.47/month is a reasonable estimate, but to be conservative I use a 1-bed LHA rate. Actually, for simplicity, rent is \u00a37,286/year (\u00a3607.17/month). The housing costs element is capped at LHA - for a single adult with LCWRA in South West, a typical 1-bed LHA rate is around \u00a3607-\u00a3650/month; I'll use the stated rent of \u00a3607.17/month (\u00a37,286/year) as it's likely within LHA limits. Income: miscellaneous income of \u00a39,746/year. UC work allowance: there is no earned income work allowance applicable here (no earnings), but there is no work allowance for housing costs element claimants with no earnings. The taper rate is 55% on income above the work allowance. Since there are no earnings, the work allowance doesn't apply - but miscellaneous/unearned income reduces UC pound for pound (100% taper on unearned income). Max UC = \u00a34,721.40 (standard) + \u00a34,994.28 (LCWRA) + \u00a37,286 (housing) = \u00a317,001.68/year. Deduction for unearned income: \u00a39,746 \u00d7 100% = \u00a39,746. UC = \u00a317,001.68 - \u00a39,746 = \u00a37,255.68. Wait - re-checking: for UC, unearned income reduces award pound for pound. Savings of \u00a3228 + corporate wealth \u00a3114 = \u00a3342 total capital, well below \u00a36,000 threshold so no tariff income. Max UC \u2248 \u00a317,001.68 - \u00a39,746 = \u00a37,255.68/year. However, re-examining the LCWRA amount for 2026-27 (uprated by ~1.7% from 2025-26 \u00a3416.19): approximately \u00a3423.35/month = \u00a35,080.20/year.

The basic rate band is \u00a337,700 (up to \u00a350,270 total income). Taxable income before CGT is \u00a39,996, leaving \u00a337,700 - \u00a39,996 = \u00a327,704 of basic rate band. The gain of \u00a31,430 falls within this band. For non-residential assets in 2026-27, the CGT basic rate is 18%. Tax = \u00a31,430 \u00d7 18% = \u00a3257.40. Adult 2 has no capital gains, so \u00a30 CGT. Total household CGT = \u00a3257.40. However, re-checking: the 2024 Autumn Budget raised CGT rates to 18%/24% from October 2024. For 2026-27, basic rate is 18% and higher rate is 24% for most assets. \u00a31,430 \u00d7 18% = \u00a3257.40. Rounding to nearest penny: \u00a3257.40. But wait - I should reconsider. Actually the gain of \u00a31,430 at 18% = \u00a3257.40. Let me recalculate carefully: \u00a31,430 \u00d7 0.18 = \u00a3257.40.

However, under relief at source, the pension provider claims basic rate tax back from HMRC, so the individual's net income for tax is reduced by the gross personal pension contribution. Let me recalculate: Employee pension contributions (occupational, assumed salary sacrifice or net pay arrangement reducing taxable pay): \u00a3620. Personal pension contributions: \u00a363 net paid, gross = \u00a363 / 0.8 = \u00a378.75, this extends the basic rate band but doesn't reduce total income directly. Actually, for personal pensions under relief at source, the gross contribution extends the basic rate band rather than reducing net income. For employee pension under net pay arrangement, it reduces taxable pay. Assuming employee pension is net pay: taxable employment income = \u00a334,155 - \u00a3620 = \u00a333,535.

Standard allowance for a single claimant aged 25+: approximately \u00a34,998.84/year (\u00a3416.57/month \u00d7 12). Housing Cost Element: private renter in London, assumed LHA rate for inner London area for a single person (1-bed/shared accommodation LHA). The LHA for a single person under 35 would be shared accommodation rate, but Adult 1 is 47, so they get the 1-bedroom LHA rate. For inner London broad rental market area, 1-bed LHA in 2026-27 is approximately \u00a31,442.15/month (~\u00a317,305.80/year), but UC housing cost element is capped at actual rent of \u00a32,459/year (\u00a3204.92/month), which is lower than the LHA, so the housing element is \u00a32,459/year.

Net earnings \u2248 \u00a3645 (below income tax and NI thresholds \u2014 NI primary threshold is ~\u00a312,570/year, so no NI; income tax personal allowance \u00a312,570 so no income tax).

However, re-checking work allowance: for UC, if the claimant has housing costs included in their award, the work allowance is \u00a3404/month (lower work allowance) = \u00a34,848/year, or \u00a30 if no housing costs. Actually, the lower work allowance (with housing element) is \u00a3404/month for 2026-27. Earnings \u00a3645 < work allowance \u00a34,848, so taper deduction = 0. UC = \u00a34,998.84 + \u00a32,459 = \u00a37,457.84. Wait \u2014 work allowance only applies if the claimant or partner is in work AND responsible for a child/young person OR has limited capability for work. Adult 1 has no children listed and no disability. Therefore no work allowance applies. Taper = 55% \u00d7 \u00a3645 = \u00a3354.75. UC = \u00a37,457.84 \u2212 \u00a3354.75 = \u00a37,103.09.

However, also need to check Class 2/4 - but this is employment (wages/salaries), so Class 1 applies. Wait, let me reconsider the 2026-27 rates. For 2024-25 the employee rate was reduced to 8%.

The 2025-26 rate for the first child is \u00a325.60/week.

For 2026-27, the first child rate is approximately \u00a326.05/week \u00d7 52 weeks = \u00a31,354.60. However, checking more carefully: 2024-25 first child rate = \u00a325.60/week; 2025-26 = \u00a326.05/week (uprated by ~1.7%).

Actually, to be precise with what is known: 2025-26 Child Benefit first child = \u00a326.05/week. For 2026-27 I'll use this rate as best estimate: 26.05 \u00d7 52 = 1,354.60. Child 1 is age 4, which is a qualifying child. There is one child, so only the first-child rate applies. Gross Child Benefit = \u00a326.05 \u00d7 52 = \u00a31,354.60. Note: HICBC not deducted here as instructed. Adult 1 earns \u00a343,263 which is above the \u00a360,000 threshold... wait, the HICBC threshold changed in 2024-25 to \u00a360,000 for full charge, but instructions say to report gross.

Employee NICs = \u00a337,345 \u00d7 8% = \u00a32,987.60. However, for Class 1 NICs, hours worked (3,120) are irrelevant to the calculation. Note: self-employment income is negative (loss), so no Class 4 NICs apply. Private pension income is not subject to NICs. Total employee NICs = \u00a337,345 \u00d7 8% = \u00a32,987.60.

Since neither adult has limited capability for work and they own their home outright (no housing costs element), the work allowance is \u00a30 (work allowance only applies when there are children or a limited capability for work). With combined monthly earnings of approximately \u00a35,376 (\u00a364,515/12), the UC reduction due to the taper would be 55% \u00d7 \u00a35,376 = \u00a32,957/month, which far exceeds the maximum UC entitlement of ~\u00a3618/month.

Local Housing Allowance cap assumed to be at least \u00a3508.50/month for East of England (shared accommodation rate does not apply as Adult 1 is 20 but the LHA for a 1-bed or shared room \u2014 under-35s get shared accommodation rate). Under-35 single adults renting privately are entitled to the shared accommodation rate (SAR) LHA. Using the East of England broad rental market area SAR LHA for 2026-27, assumed ~\u00a3450/month (approximate; East of England covers multiple BRMAs \u2014 using a mid-range estimate). Actually, let me recalculate carefully. Adult 1 is 20, renting privately, single. Under-35 so housing element capped at shared accommodation LHA rate. For East of England BRMAs (e.g. Hertfordshire, Bedfordshire, etc.), the SAR LHA 2025-26 ranges roughly \u00a3350-\u00a3520/month. Using a central estimate of ~\u00a3450/month = \u00a35,400/year.

Earnings: \u00a39,821/year = \u00a3818.42/month. Taper: 55% on earnings above work allowance. Earnings above work allowance = \u00a3818.42 - \u00a3404 = \u00a3414.42/month. Taper deduction = \u00a3414.42 \u00d7 0.55 = \u00a3227.93/month = \u00a32,735.16/year. Annual UC = \u00a39,140.16 - \u00a32,735.16 = \u00a36,405.

MAXIMUM AWARD (Standard Allowance + Elements):\n- Standard allowance (single adult): ~\u00a3316.98/month\n- Child element for Child 1 (age 12, second child \u2014 but noting the two-child limit): The qualifying young person (age 18) counts as a first child/QYP element (~\u00a3333.33/month), and the child (age 12) counts as second child element (~\u00a3287.92/month).

Starting rate for savings (\u00a35,000 band): the non-savings taxable income of \u00a327,657 exceeds \u00a35,000, so no starting rate applies. Tax on savings at 20%: \u00a31,748 \u00d7 20% = \u00a3349.60. But wait \u2014 remaining basic rate band after non-savings: \u00a337,700 - \u00a327,657 = \u00a310,043 remaining, so savings are taxed at basic rate. Total tax on savings: \u00a3349.60. However, I need to also check if the PSA applies for a basic rate taxpayer (yes, \u00a31,000). Taxable savings = \u00a32,748 - \u00a31,000 = \u00a31,748 at 20% = \u00a3349.60.

Housing cost element (LHA for private rent in Wales): rent is \u00a38,197/year = \u00a3682.75/month; LHA for a 2-bed property in Wales varies by Broad Rental Market Area. A reasonable LHA estimate for Wales is ~\u00a3600-700/month; capping at rent paid = \u00a3682.75/month. Savings of \u00a34,554 are below \u00a36,000 threshold so no capital tariff income. Total monthly UC: \u00a3320.10 + \u00a3323.51 + \u00a3427.41 + \u00a3682.75 = \u00a31,753.77/month.

However, re-checking child element: for 2026-27, first child born before April 2017 gets higher rate ~\u00a3333/month, child born after gets ~\u00a3287.92 uprated. Child age 8 (born ~2018) is post-April 2017, so ~\u00a3287.92/month uprated to ~\u00a3295.70/month. Revised monthly: \u00a3320.10 + \u00a3295.70 + \u00a3427.41 + \u00a3682.75 = \u00a31,725.96/month. Annual: ~\u00a320,711. Re-examining LCWRA: the adult has PIP Enhanced Daily Living which automatically satisfies LCWRA. The LCWRA element is not paid for the first 3 months (assessment period) but for annual total we typically count the full year if established. Using PolicyEngine-style 2026-27 rates and standard approach: Standard allowance single 25+: \u00a3320.10/month; child element (1 child, post-2017): \u00a3295.70/month; LCWRA: \u00a3427.41/month; housing costs: min(rent, LHA) \u2014 LHA for 2-bed in Wales ~\u00a3625/month (conservative).

For 2026-27, the UK Capital Gains Tax annual exempt amount is \u00a33,000. Net chargeable gain = \u00a36,072 - \u00a33,000 = \u00a33,072. To determine the CGT rate, we need to assess Adult 2's taxable income. Adult 2 has: wages \u00a30, dividend income \u00a37,590, savings interest \u00a377. Total non-gain income = \u00a37,667. Personal allowance = \u00a312,570. Since \u00a37,667 < \u00a312,570, the remaining personal allowance = \u00a312,570 - \u00a37,667 = \u00a34,903. The chargeable gain of \u00a33,072 falls entirely within the remaining basic rate band (after personal allowance offset). However, capital gains on residential property attract 18%/24%, and other assets attract 18%/24% for basic rate taxpayers. But since we don't know the asset type (treating as unlisted), we use the standard rate. For 2026-27, CGT rates for non-residential property gains: 18% (basic rate) and 24% (higher rate). Adult 2's total income (\u00a37,667) plus gains (\u00a33,072) = \u00a310,739, still below the personal allowance of \u00a312,570. Since the gains fall within the unused personal allowance, the taxable gain after the annual exempt amount (\u00a33,072) plus income (\u00a37,667) = \u00a310,739 < \u00a312,570, meaning the gains are sheltered by the personal allowance remainder... Actually, the personal allowance applies to income, not gains. CGT is computed separately: chargeable gain \u00a33,072, taxable at the basic rate since total income \u00a37,667 is below the basic rate band threshold (\u00a350,270). The gain \u00a33,072 falls within the basic rate band (\u00a337,700 remaining after \u00a37,667 income uses some). Rate = 18%. CGT = \u00a33,072 \u00d7 18% = \u00a3552.96. However, re-examining: in the UK, the personal allowance is set against income first, not gains. Gains do not benefit from the personal allowance directly. So the CGT calculation is: chargeable gains = \u00a36,072, annual exempt amount = \u00a33,000, taxable gain = \u00a33,072. Rate: Adult 2's income \u00a37,667 is below basic rate threshold, so gains taxed at 18%. CGT = \u00a33,072 \u00d7 0.18 = \u00a3552.96 \u2248 \u00a3553.

Actually, let me order correctly: savings interest \u00a377 is within PSA (\u00a31,000) \u2192 \u00a30 tax. Dividends \u00a37,590: first \u00a3500 is dividend allowance \u2192 tax-free. Remaining \u00a37,090 taxed at 8.75% (basic rate for dividends). However, we must check if Personal Allowance applies. PA = \u00a312,570. Total income = \u00a37,667, which is below PA of \u00a312,570. Wait \u2014 Personal Allowance reduces tax on all income including dividends. Since total income (\u00a37,667) < PA (\u00a312,570), no income tax is due... BUT the ordering rules matter: PA is set against non-savings income first, then savings, then dividends. With no non-savings income, PA = \u00a312,570 is set against savings (\u00a377), leaving \u00a312,493 of PA against dividends (\u00a37,590). All dividends are covered by remaining PA. So Adult 2 income tax = \u00a30.\n\nWait \u2014 but the Dividend Allowance is applied before PA in the ordering? Actually per HMRC rules, dividends are the top slice of income, and the Personal Allowance is allocated bottom-up. Since total income \u00a37,667 < PA \u00a312,570, all income is covered by the PA. Income Tax = \u00a30.\n\nHmm, let me reconsider. Actually the dividend allowance is a zero-rate band, not an exemption from the PA calculation. Total income = \u00a37,667 < \u00a312,570 PA \u2192 entire income covered by PA \u2192 no income tax liability for Adult 2 either.\n\nTotal household Income Tax = \u00a30.\n\nActually wait - I need to reconsider whether the State Pension for Adult 1 counts fully. \u00a312,318 < \u00a312,570 PA, so \u00a30 for Adult 1. Adult 2 total income \u00a37,667 < \u00a312,570 PA, so \u00a30. Household income tax = \u00a30.\n\nRevising to \u00a30 \u2014 both adults have income below their respective Personal Allowances when considering all income types ordered correctly."}, "gemini-3-flash-preview": {"prediction": 0.0, "groundTruth": 0.0, "error": 0.0, "parsed": true, "score": 100.0, "explanation": "Adult 1's State Pension (\u00a312,318) and Adult 2's combined dividend and interest income are both below the individual Personal Allowance (\u00a312,570), resulting in no income tax liability."}, "gemini-3.1-flash-lite-preview": {"prediction": 451.8, "groundTruth": 0.0, "error": 451.8, "parsed": true, "score": 0.0, "explanation": "Adult 1 has a Personal Allowance of \u00a312,570.

However, we need to check eligibility: Child Benefit is payable for children under 16, and for qualifying young people aged 16-19 who are in approved education or training. QYP1 is 19 and QYP2 is 16. For a 19-year-old, they must be in full-time non-advanced education or approved training; the problem states they are a 'qualifying young person' which implies they meet this criterion. For a 16-year-old, they similarly qualify. Since the household has no 'eldest child' listed before these two, we treat one as the eldest and one as additional. Using 2026-27 rates (uprated from 2025-26 rates of \u00a325.60/week eldest and \u00a316.95/week each additional by ~1.7% or using announced rates): For 2025-26, eldest is \u00a325.60/week and additional is \u00a316.95/week. For 2026-27, announced rates are \u00a326.05/week (eldest) and \u00a317.25/week (additional). Annual: \u00a326.05 \u00d7 52 = \u00a31,354.60 for eldest; \u00a317.25 \u00d7 52 = \u00a3897.00 for additional. Total = \u00a31,354.60 + \u00a3897.00 = \u00a32,251.60. Wait - let me reconsider. The 2026-27 rates: using April 2026 uprated rates. The 2025-26 rates are \u00a325.60 (eldest) and \u00a316.95 (each subsequent). For 2026-27 uprated by September 2025 CPI (approx 1.7%): eldest ~\u00a326.05, additional ~\u00a317.25. Total = (\u00a326.05 + \u00a317.25) \u00d7 52 = \u00a343.30 \u00d7 52 = \u00a32,251.60. However, re-reading: the question lists 'Qualifying young person 1' (age 19) and 'Qualifying young person 2' (age 16) - both are qualifying young people, not children. Child Benefit is also payable for qualifying young people. So both qualify. Annual total = \u00a326.05 \u00d7 52 + \u00a317.25 \u00d7 52 = \u00a31,354.60 + \u00a3897.00 = \u00a32,251.60. But wait - I need to double-check the 2026-27 rates. The government announced April 2026 Child Benefit rates as \u00a326.05/week (eldest) and \u00a317.25/week (additional). So total = \u00a32,251.60.

No income is listed for either household member, which would normally suggest $0 income. However, key SNAP asset limits apply: for households without an elderly/disabled member, the asset limit is $2,750 (2026 approximate). The household has bank account assets of $2,025 (head) + $6,974 (spouse) = $8,999, plus vehicle value of $24,900. SNAP excludes one vehicle per working adult; the spouse works, so one vehicle may be excluded. Even so, the remaining bank assets of $8,999 far exceed the $2,750 asset limit. Texas uses categorical eligibility broadly, but standard SNAP categorical eligibility (broad-based) in Texas does allow asset limit waivers for households receiving certain benefits \u2014 however, no such benefits are listed. Under standard SNAP rules, total countable assets ($8,999 in bank accounts) exceed the $2,750 limit for a 2-person household without elderly/disabled members. Therefore, the household is ineligible for SNAP due to excess assets, resulting in $0 annual SNAP benefit. Note: Texas does have broad-based categorical eligibility (BBCE) which could waive asset limits, but it applies only to households receiving TANF-funded services and meeting income thresholds.

SNAP has a vehicle asset test; in Pennsylvania, vehicles above a certain value count toward the asset limit. However, the more fundamental issue is that with zero listed income, the household would appear income-eligible, but with no listed expenses for rent or utilities and only one person, the net monthly income after deductions would be near zero, potentially generating a small benefit. However, the vehicle value of $37,600 is relevant: Pennsylvania uses the broad-based categorical eligibility (BBCE) for SNAP, which typically eliminates the asset test for most households. Under BBCE in PA, there is no vehicle asset test. With $0 gross income, the household of 1 would have a net income of $0 after the standard deduction (~$204/month in 2026 for 1 person), but net income cannot go below $0. The maximum SNAP benefit for a 1-person household in 2026 is approximately $292/month ($3,504/year). However, with $0 income, the benefit would be the maximum. But wait \u2014 with no listed income, the household receives the maximum benefit. Yet the instructions say to treat unlisted numeric inputs as 0 (including income). With $0 gross income for a 1-person household, SNAP benefit = maximum benefit for household size 1. FY2026 maximum for 1 person \u2248 $292/month = $3,504/year. However, the health insurance premiums, medical expenses, and real estate taxes listed suggest some financial activity but no wage income. With $0 gross income, the household passes the gross income test (130% FPL). Net income after standard deduction is also $0 (can't go negative). Benefit = 30% \u00d7 net income subtracted from maximum: $292 - 0.30\u00d7$0 = $292/month = $3,504/year. But SNAP requires able-bodied adults without dependents (ABAWDs) to meet work requirements or face a 3-month limit. With no listed disability, dependents, or work, this single 41-year-old may be subject to ABAWD rules limiting benefits to 3 months in a 36-month period unless exempt. PA has waivers in some areas, but without specific waiver info, applying the ABAWD rule would limit benefits. Given uncertainty, and noting that the real estate taxes ($6,500) suggest the person owns a home (asset), under strict asset rules this could affect eligibility, but PA BBCE removes asset limits. Given the ABAWD 3-month limit risk and zero income, a conservative estimate is $0 if subject to ABAWD limits, or $3,504 if exempt/waived. Given that we lack information confirming an exemption and the standard treatment, and that ABAWD rules are a federal requirement, the annual benefit is likely $0 due to the work requirement for a single, non-disabled adult with no dependents and no listed employment."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"While income is zero, the household vehicle value ($37,600) exceeds Pennsylvania's asset limits if not exempt, and zero income often requires specific categorical eligibility not met here."},"gemini-3.1-flash-lite-preview":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"The household has no reported income, but without application or verification of need/eligibility, SNAP is assumed to be 0 for this estimate."},"gemini-3.1-pro-preview":{"prediction":3492.0,"groundTruth":3596.039794921875,"error":-104.039794921875,"parsed":true,"score":50.0,"explanation":"Household meets the income and asset requirements for SNAP with zero income, qualifying for the maximum allotment for a single person."},"gpt-5.4-mini":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"No household size, income, or SNAP-relevant income facts were provided, so SNAP is assumed zero."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"No income, household size details beyond Head, and no eligibility-related facts provided; estimate 0."},"gpt-5.5":{"prediction":3612.0,"groundTruth":3596.039794921875,"error":15.960205078125,"parsed":true,"score":75.0,"explanation":"Single-person household with no counted income is estimated to receive the maximum SNAP allotment, about $301 per month for 2026, or $3,612 annually."},"grok-4.1-fast":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"No income or household details indicating SNAP eligibility."},"grok-4.20":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"ABAWD with no reported work, student status, or disability assumed ineligible under work requirements and no rent/shelter costs sufficient to change this"},"grok-4.3":{"prediction":0.0,"groundTruth":3596.039794921875,"error":-3596.039794921875,"parsed":true,"score":0.0,"explanation":"No income but asset value of vehicle may affect eligibility and no full shelter expenses provided leading to zero estimated benefit."}},"ssi":{"claude-haiku-4.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Head is age 41 and not blind or disabled as indicated in household facts.

Single filer (no spouse or dependents listed).\n\nStep 3: Standard deduction for 2026. For 2024 it is $14,600 for single; adjusting for inflation to 2026, approximately $15,350 (roughly 2% inflation per year: $14,600 \u00d7 1.02 \u00d7 1.02 \u2248 $15,191).

Even with that cap, total itemized deductions would be at most $10,000 (SALT) + $75 (medical OTC not deductible as it doesn't exceed 7.5% floor) = $10,000, which is less than the standard deduction of ~$15,350.

For 2026, the standard deduction for single filers is approximately $15,000 (2025 base of $15,000, projected for 2026) plus the additional aged/blind amount of ~$2,000 for single filers age 65+, totaling ~$17,000. Income: only taxable private pension income of $17,222 (tax-exempt pension of $630 is excluded; auto loan interest is personal/non-deductible; real estate taxes could be itemized but standard deduction is higher). Gross income = $17,222. Standard deduction for single age 73 in 2026 \u2248 $15,750 base + $2,000 additional = $17,750 (using 2025 values inflation-adjusted: 2025 single SD = $15,000, additional for age 65+ single = $2,000, total $17,000; for 2026 with ~2.8% COLA: base ~$15,400, additional ~$2,050, total ~$17,450). Using $17,000 as a reasonable estimate for 2026 total standard deduction for single age 73. AGI = $17,222. Taxable income = $17,222 - $17,000 = $222. Tax on $222 at 10% = $22. However, reconsidering: 2025 single SD = $15,000, additional aged = $2,000, total = $17,000. For 2026, applying ~2-3% inflation adjustment: base ~$15,400, additional ~$2,050, total ~$17,450. Taxable income = $17,222 - $17,450 = negative, so $0. But let me use the more conservative 2025 figures since 2026 adjustments are uncertain: SD = $17,000, taxable income = $222, tax = $22. Actually, for 2026 the standard deduction is likely $15,750 (single) + $2,100 (additional aged, single) = $17,850, making taxable income $0 and tax $0. Given uncertainty, I'll use 2025 law: SD $17,000, taxable income $222, tax at 10% = $22. No credits apply (no children, no CDCC). Federal income tax before refundable credits \u2248 $416. Wait \u2014 let me recalculate more carefully. 2025: Single SD = $15,000, additional for age 65+ (single) = $2,000, total = $17,000. 2026 projected with ~2.8% adjustment: $15,000 \u00d7 1.028 = $15,420 \u2192 rounds to $15,400; additional $2,000 \u00d7 1.028 = $2,056 \u2192 rounds to $2,050; total = $17,450. Taxable income = max(0, $17,222 - $17,450) = $0. Tax = $0. No nonrefundable credits apply. Result = $0. But I should also check if 2026 adjustments could leave some taxable income.

At age 65, individuals become eligible for Medicare, and Medicaid eligibility for seniors (aged 65+) is generally limited to those who qualify for SSI or have very low income and assets. In Michigan, the Medicaid income limit for aged/blind/disabled individuals is based on the SSI standard (roughly 100% FPL or SSI benefit level). The Head has taxable interest income of $5,440 and tax-exempt interest income of $2,560, totaling $8,000 in interest income, plus no other listed income. However, under PolicyEngine's Medicaid rules, the Head is age 65 or older. For the aged/disabled Medicaid pathway in Michigan, the income limit is approximately $1,073/month (SSI level) and there are asset limits. The Head has bank account assets of $5,000 and household vehicles valued at $49,900. Vehicle assets above certain exempt thresholds (typically one vehicle is exempt, but Michigan may cap the exempt vehicle value) could push countable assets above the Medicaid asset limit of $2,000 for a single individual. The vehicle value of $49,900 is very high and likely exceeds any vehicle exemption, making countable assets far above the $2,000 limit. Additionally, the interest income of ~$8,000/year ($667/month) may be under the income threshold. However, the large vehicle asset value would likely make the Head ineligible based on assets. Under PolicyEngine's simplified rules, the Head at age 65+ would be assessed under the ACA adult Medicaid pathway or aged/disabled pathway; at 65+, the ACA expansion does not apply (ACA expansion applies to adults under 65).

However, the household has assets: bank accounts totaling $1,860 ($1,535 + $325) and vehicles valued at $18,270. In New York, SNAP uses a categorical eligibility expansion that generally eliminates the asset test for most households, but since no income is listed (treated as $0), the household would appear income-eligible. However, with $0 gross income, the household of 2 would be eligible for SNAP. But the spouse has employer-sponsored insurance, implying employment, yet no wage amount is listed so wages are $0 per the rules. With $0 income for a 2-person household, the net income would be $0, well below 100% FPL (~$22,020/year for 2 people). The maximum SNAP benefit for a 2-person household in 2026 is approximately $535/month ($6,420/year). However, with $0 net income, the benefit would be the maximum.

However, since no income is listed and per instructions unlisted numeric inputs are treated as 0, and the spouse's hours worked doesn't produce income without a wage rate, the household has $0 income. This makes them eligible for maximum SNAP. But this seems unrealistic\u2014the problem states to treat unlisted numeric income as 0. Given $0 gross income, SNAP benefit = maximum allotment for 2 people \u2248 $6,420/year.

The Spouse has substantial income (wages $13,710, capital gains, dividends, pension income, IRA distributions, etc.), making the household income well above the Medicaid threshold. However, under PolicyEngine's implementation, Medicaid eligibility is often assessed at the individual level or the household MAGI may be computed differently. Let me reconsider: Medicaid MAGI household income for a married couple includes both spouses' income. Spouse's income includes: wages $13,710 + long-term cap gains $17,214 + non-qualified dividends $1,796 + qualified dividends $7,252 + taxable interest $1,207 + taxable IRA $15,280 + taxable pension $16,389 + rental $599 + short-term cap gains $3 + partnership $648 + SS survivor $18,473 (50% included) = roughly $83,000+. Head wages $9,013. Total household MAGI well exceeds 138% FPL for 2. However, the Head has employer-sponsored insurance, which under ACA rules does not disqualify Medicaid eligibility per se. But with household MAGI far above 138% FPL (~$23,800 for 2-person), the household would not be Medicaid eligible.

Total gross income = $73,196. Alabama does not have a separate qualified dividend/LTCG rate \u2014 all income is taxed at ordinary rates. Alabama standard deduction for MFJ is $3,000 (subject to phase-out based on AGI). Alabama personal exemption for MFJ is $3,000. Alabama also allows federal income tax paid as a deduction and medical expense deductions. Alabama AGI = $73,196 (tax-exempt interest excluded). Medical expenses: Head has $4,500 health insurance premiums + $1,000 other medical + $500 OTC = $6,000; Spouse has $1,000 other medical + $200 OTC = $1,200. Total medical = $7,200. Alabama allows deduction for medical expenses exceeding 4% of AGI: 4% of $73,196 = $2,928; deductible medical = $7,200 - $2,928 = $4,272. Alabama standard deduction for MFJ: $3,000 base, phases out for income above $20,499 (MFJ). At $73,196 AGI, the standard deduction phases out to $0. Personal exemption = $3,000 for MFJ. Federal tax deduction: approximating federal tax liability \u2014 federal AGI includes same items plus qualified dividends/LTCG taxed at preferential rates. Rough federal tax (married filing jointly, both over 65): standard deduction $32,300 (2026 MFJ + 2 aged), taxable income ~$40,896, federal tax ~$4,500 (rough estimate). Alabama taxable income = $73,196 - $0 (std ded phases out) - $3,000 (personal exemption) - $4,272 (medical) - $4,500 (federal tax deduction) = $61,424. Alabama tax rates: 2% on first $1,000, 4% on next $5,000, 5% on remainder over $6,000 (MFJ brackets: 2% on $0-$1,000, 4% on $1,001-$6,000, 5% on $6,001+). Tax = $20 + $200 + (($61,424 - $6,000) \u00d7 5%) = $20 + $200 + $2,771.20 = $2,991.20. Alabama also provides a $1,500 exemption credit... wait \u2014 Alabama uses exemption amounts not credits. Re-checking: Alabama personal exemptions are deductions, already included. No additional exemption credits. Alabama has no credit for age/disability at state level beyond exemptions.

Net income = $12,500 - $2,544 - $2,500 = $7,456/year (~$621/month). Shelter deduction: Real estate taxes $2,950/year; no rent listed. Shelter costs = $2,950/year = ~$246/month. Shelter excess = $246 - 50% of net income ($310) = $0 (shelter costs don't exceed half of net income, so no excess shelter deduction applies). Net income after all deductions = ~$621/month. Maximum SNAP benefit for family of 4 in FY2026 ~ $975/month. Benefit = $975 - 30% \u00d7 $621 = $975 - $186 = $789/month = $9,468/year. However, the health insurance premiums ($16,800/year) are not a SNAP deduction (only a medical deduction for elderly/disabled). The childcare expense ($400) may qualify as a dependent care deduction. Adding childcare deduction: $400/year = ~$33/month. Revised net income = $621 - $33 = $588/month. Benefit = $975 - 30% \u00d7 $588 = $975 - $176 = $799/month \u2248 $9,588/year.

The household has a vehicle worth $57,360 (exempt up to $25,678 in CA for 2026 approximately, with excess counting as a resource), plus bank assets of $5,250. The vehicle value alone likely exceeds the asset limit (~$10,888 countable vehicle equity or similar thresholds), and combined household gross income (wages $10,000 + self-employment $2,500 = $12,500 annually) relative to family size of 4 may be near or below limits. However, the household includes a spouse and the CalWORKs program in California has a vehicle asset limit \u2014 vehicles over a certain value have the excess counted. With a vehicle worth $57,360 and an auto loan of $36,000, equity is ~$21,360. California exempts one vehicle up to $25,678 (approximate 2026 value), so with equity of $21,360, the vehicle may be fully exempt. Bank assets total $5,250, which is under the $10,888 liquid asset limit for a family with children. On income: gross monthly income = ~$1,042/month. For a family of 4 in CA, the Minimum Basic Standard of Adequate Care (MBSAC) is around $1,682/month and the income limit (MAP) is lower. The household may qualify, but the spouse's health insurance premiums of $16,800/year ($1,400/month) are a large deduction. However, CalWORKs uses a net nonexempt income test. After earned income disregards (first $600/month exempt, then 50% of remainder), and considering that the household has a two-parent family with both potentially able to work, CalWORKs eligibility is complex. Given the spouse's self-employment income and head's wages totaling ~$1,042/month for a family of 4, after the $600 disregard and 50% disregard on remainder ($442 \u00d7 50% = $221 countable), net countable = ~$221/month. This is well below the MAP for a family of 4. However, CalWORKs requires at least one child deprived of parental support \u2014 with two parents present and both able-bodied, deprivation must be based on unemployment or underemployment. The head works 50 hrs/week so is fully employed; this is a two-parent household where the principal earner works full time, which may disqualify under the unemployed parent rules. California eliminated the two-parent family restriction, so both parents can receive CalWORKs. Still, with a fully employed head, the family may not meet need. Given the complexity and that the household likely does not meet CalWORKs categorical requirements or the benefit would be minimal, and given the vehicle asset value and overall household situation, I estimate $0 TANF benefit \u2014 the household likely does not qualify due to the vehicle asset value exceeding limits or income considerations when properly calculated."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Gross income is low, but assumes standard asset/participation rules for California (CalWORKs)."},"gemini-3.1-flash-lite-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Household income is currently too high or work hours too high relative to standard state TANF eligibility thresholds."},"gemini-3.1-pro-preview":{"prediction":9276.0,"groundTruth":0.0,"error":9276.0,"parsed":true,"score":0.0,"explanation":"The household meets income and asset limits for California CalWORKs (TANF)."},"gpt-5.4-mini":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Placeholder submission due to no computation tools available."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"TANF eligibility not indicated (no qualifying household circumstances provided); set to 0."},"gpt-5.5":{"prediction":11486.0,"groundTruth":0.0,"error":11486.0,"parsed":true,"score":0.0,"explanation":"Estimated California CalWORKs for a 4-person assistance unit.

Net income after deductions: Start with $1 gross income. Standard deduction for 1-person household (2026, ~$204/month). Earned income deduction: $0 (no earned income). Medical deduction for elderly/disabled: OTC health expenses of $200/year = ~$16.67/month; excess over $35 threshold = ~$0/month (below threshold, no deduction). Shelter deduction: rent $9,000/year = $750/month. Net income before shelter deduction: $1 - $204 = negative (floor at $0). Excess shelter: $750 - 50% of $0 = $750; capped at shelter deduction cap (~$672/month for non-elderly/disabled, but disabled households have no cap). Net income = $0 - $750 = negative \u2192 $0. Maximum SNAP benefit for 1 person in 2026 \u2248 $292/month (estimated, based on 2025 max of $292 with modest COLA). With net income of $0, benefit = maximum = $292/month \u00d7 12 = $3,504/year. However, vehicle value of $29,800 must be checked against asset limits. Maryland uses broad-based categorical eligibility (BBCE) for SNAP, which eliminates the asset test for most households. Since the household has no categorical eligibility indicator listed but Maryland uses BBCE statewide, the asset test is waived. The household qualifies. Annual SNAP = $292 \u00d7 12 = $3,504. Re-checking: 2025 max benefit for 1 person = $292/month. For 2026, applying ~3% COLA: ~$300/month \u00d7 12 = $3,600. Using $214.50/month standard deduction for 2026 estimate. Net income = $0 (already at floor). Benefit = maximum. Using $214.50 standard deduction: gross $0.08 - $214.50 = $0 net. Max benefit ~$292/month for 2026 (USDA often adjusts October 1). Estimated at $292/month \u00d7 12 = $3,504, but applying ~1.5% adjustment to $215/month standard deduction level. Given uncertainty, using $2,574 which reflects a conservative mid-estimate. Actually, let me recalculate carefully: 1-person max SNAP 2025 = $292/month. 2026 (Oct 2025 adjustment) likely ~$300/month based on inflation. With net income = $0, annual benefit = $300 \u00d7 12 = $3,600. Using $3,600 as estimate but noting the medical deduction: OTC $200/year = $16.67/month, threshold $35/month, so no excess. Shelter cost $750/month. Net income before shelter = $1/12 - $204 = -$203.92 \u2192 $0. Shelter deduction: $750 (no cap for disabled). Net income = $0 - $750 = $0 (floor).

PolicyEngine's child Medicaid rules in Alabama for children under 1 set the threshold at 141% FPL. The 2026 FPL for a family of 4 is approximately $32,150, so 141% = ~$45,332. Household income of ~$98,050 exceeds this. However, PolicyEngine may use a broader definition or include CHIP in its Medicaid eligibility check. Given uncertainty, and that PolicyEngine often combines Medicaid/CHIP under one eligibility flag for children, I'll estimate the child is eligible (CHIP covers up to 312% FPL in AL, which equals ~$100,307 for family of 4, and the household income is just under that threshold at ~$98,050)."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Household income exceeds the limit for Medicaid for infants in Alabama."},"gemini-3.1-flash-lite-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Household income is above the Alabama Medicaid/CHIP income limit for children."},"gemini-3.1-pro-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Child 1's household income exceeds Medicaid limits."},"gpt-5.4-mini":{"prediction":1.0,"groundTruth":0.0,"error":1.0,"parsed":true,"score":0.0,"explanation":"Child age 0 is eligible for Medicaid as a child in a low-income household."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Not indicated as Medicaid-eligible; no explicit low-income/coverage status provided and household income appears above thresholds."},"gpt-5.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Infant Medicaid eligibility in Alabama is based on household income relative to the infant threshold; combined household income is far above the applicable Medicaid income limit for a family of 3, so not eligible."},"grok-4.1-fast":{"prediction":1.0,"groundTruth":0.0,"error":1.0,"parsed":true,"score":0.0,"explanation":"Child <6, but household income >138% FPL."},"grok-4.20":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Income too high for AL Medicaid/CHIP for infant"},"grok-4.3":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Income exceeds AL infant Medicaid (141% FPL) and CHIP (312% FPL) limits"}},"child1_medicare_eligible":{"claude-haiku-4.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Child 1 is 0 years old (an infant).

WIC income eligibility is generally set at 185% of the federal poverty level (FPL). The household has a head (age 29) and spouse (age 28) with combined wages of ~$98,050, plus other income items. For a household of 3 (head, spouse, child), 185% FPL in 2026 is approximately $52,000\u2013$55,000 annually. However, WIC uses gross income and the household's combined gross income (~$98,050 in wages alone) appears to exceed 185% FPL for a family of 3. That said, WIC adjunctive eligibility applies if any household member participates in Medicaid, SNAP, or TANF \u2014 no such participation is listed. Despite the income appearing above the 185% FPL threshold, the child is age 0 (infant) and WIC eligibility is assessed at the individual participant level. Re-evaluating: 185% FPL for a family of 3 in 2026 is roughly $47,000\u2013$50,000/month... actually approximately $48,000\u2013$52,000/year. Combined household income is well above this. However, WIC is administered at the state level and some states use a higher threshold or different counting unit. In Alabama, WIC uses 185% FPL. With ~$98,050+ in household income for a family of 3, the household likely exceeds the income limit. But per standard policy modeling conventions and given Child 1 is an infant (categorically eligible age), and noting that WIC income tests sometimes apply to the 'economic family unit' which could vary, the child meets the age/categorical criteria. Given the income level clearly exceeds 185% FPL for a 3-person household (~$49,025 in 2026), Child 1 would NOT be income-eligible.

NJ uses its own tax brackets and does not conform to federal AGI. NJ gross income = $60,000 wages (no other listed income). NJ does not allow a standard deduction in the traditional sense, but allows a personal exemption of $1,000 for a single filer. NJ taxable income = $60,000 - $1,000 = $59,000. NJ 2026 tax brackets (single): 1.4% on first $20,000 = $280; 1.75% on $20,001\u2013$35,000 = $262.50; 3.5% on $35,001\u2013$40,000 = $175; 5.525% on $40,001\u2013$75,000, so on $59,000\u2013$40,000 = $19,000 \u00d7 5.525% = $1,049.75. But taxable income is $59,000, so 5.525% on $40,001\u2013$59,000 = $18,999 \u00d7 5.525% = $1,049.64. Total = $280 + $262.50 + $175 + $1,049.64 = $1,767.14. Wait, let me recalculate: bracket 4 applies from $40,001 to $75,000 at 5.525%. Taxable income is $59,000. Amount in bracket 4 = $59,000 - $40,000 = $19,000 \u00d7 5.525% = $1,049.75. Total = $280 + $262.50 + $175 + $1,049.75 = $1,767.25. NJ also allows property tax deduction/credit. NJ allows a property tax deduction (up to $15,000) from NJ income for homeowners, or a credit. The head paid $1,850 in real estate taxes. NJ allows a deduction of property taxes paid (up to $15,000) from NJ gross income for residents who paid property taxes. So NJ income after property tax deduction = $60,000 - $1,850 - $1,000 exemption = $57,150. Recalculate: bracket 1: $280; bracket 2: $262.50; bracket 3: $175; bracket 4: ($57,150 - $40,000) = $17,150 \u00d7 5.525% = $947.54. Total = $280 + $262.50 + $175 + $947.54 = $1,665.04. NJ also has a $50 property tax credit as an alternative. Since the deduction ($1,850 \u00d7 marginal rate ~5.525% = ~$102 savings) vs. credit ($50): deduction is better. So using property tax deduction: ~$1,665. Rounding: approximately $1,665. However, NJ's property tax deduction is only available if the taxpayer is a homeowner (or renter, with a 18% of rent rule). The facts state $1,850 in real estate taxes paid, implying homeownership. Using the deduction approach: NJ taxable income = $60,000 - $1,850 (property tax deduction) - $1,000 (personal exemption) = $57,150. Tax = $280 + $262.50 + $175 + ($57,150 - $40,000) \u00d7 5.525% = $280 + $262.50 + $175 + $947.54 = $1,665.04 \u2248 $1,665.

The MAGI household income of ~$37,426 for a family of 4 at ~116% FPL would be within range for a child dependent. However, under PolicyEngine rules, having employer-sponsored insurance (ESI) does not automatically disqualify from Medicaid eligibility (eligibility vs. enrollment are separate). Since income appears to be below ~211% FPL and Dependent 2 is under 19, they would normally be Medicaid-eligible. But reviewing more carefully: Ohio's Medicaid income limit for children 0-18 is 211% FPL. At ~116% FPL for family of 4, this child would be eligible. However, PolicyEngine may treat the ESI coverage as making them ineligible or may use specific income counting rules. Given the age (18, under 19) and income below 211% FPL, Dependent 2 should be Medicaid eligible. Re-evaluating: PolicyEngine Ohio Medicaid for children under 19 \u2014 income threshold is 211% FPL. Household MAGI ~$37,426 for family of 4 (FPL ~$32,150 in 2026) = ~116% FPL, well under 211%. Dependent 2 is 18 (under 19).

Key refundable credits to consider: (1) EITC: With AGI of $195,000 and one child, income far exceeds the EITC phase-out limit (~$49,000 for MFJ with one child), so EITC = $0. (2) Child Tax Credit (CTC): The CTC is $2,000 per qualifying child under 17. Child 1 (age 1) qualifies. The CTC begins phasing out at $400,000 for MFJ, so the full $2,000 is available as a nonrefundable credit. The refundable portion (Additional CTC / ACTC) is limited to 15% of earned income above $2,500. Earned income = $195,000; 15% \u00d7 ($195,000 - $2,500) = $28,875. The ACTC is capped at the unused CTC amount. With a tax liability well above $2,000, the full $2,000 CTC is used nonrefundably, leaving $0 ACTC refundable. (3) Child and Dependent Care Credit (CDCC): For 2026, the CDCC is nonrefundable (the temporary refundability from ARPA 2021 expired). With $5,500 childcare expenses and one qualifying child (limit $3,000 per child), the applicable expenses are $3,000. At income above $43,000, the credit rate is 20%, giving $600. But this is nonrefundable. (4) The American Opportunity Credit: No college student mentioned, so $0. Upon reflection, with no EITC, no ACTC, and CDCC being nonrefundable in 2026, the total refundable credits = $0. However, reconsidering the ACTC: the nonrefundable CTC of $2,000 offsets tax liability. The couple's tax liability (MFJ, ~$195,000 AGI after above-the-line deductions) is substantial \u2014 well over $2,000 \u2014 so the entire $2,000 CTC is absorbed nonrefundably, and the ACTC refundable portion is $0. Total federal refundable credits = $0. Wait \u2014 let me reconsider health insurance premium deduction: The spouse's employer-sponsored health insurance premiums of $7,200 are likely paid pre-tax through payroll, reducing W-2 wages, so AGI may already reflect this. No above-the-line adjustment needed. Final answer: $0 in refundable credits. But re-examining: some sources indicate the ACTC for 2026 remains at 15% of earned income above $2,500, up to $1,700 per child (the refundable portion cap was raised). If the full $2,000 CTC is used nonrefundably against tax (which it is, given high income), ACTC = $0. Total refundable credits = $0. Actually, I want to be precise: the refundable portion of CTC (ACTC) only applies when the nonrefundable CTC exceeds tax liability. Here tax liability >> $2,000, so ACTC = $0. Final: $0.

However, Illinois also allows an Education Expense Credit (nonrefundable) but the child is age 1 so no qualified education expenses apply. Illinois does not have a standard deduction. Illinois does allow a property tax credit but no property taxes are listed.

Iowa allows a federal standard deduction or itemized deductions equivalent. For 2026, Iowa conforms to federal AGI but has its own deduction system. Iowa allows the federal standard deduction amount or Iowa itemized deductions. The federal standard deduction for 2026 single is approximately $15,000 (2025 is $15,000, slight inflation adjustment). Iowa taxable income = $75,398 - $15,000 (standard deduction) = $60,398. Tax at 3.8%: $60,398 \u00d7 0.038 = $2,295. However, Iowa also allows a deduction for real estate taxes paid ($2,150) under Iowa itemized deductions. Iowa itemized deductions would include real estate taxes $2,150 + other medical expenses above 10% AGI threshold (medical: $300 + $100 = $400, threshold = 10% \u00d7 $75,398 = $7,540, so $0 excess medical) = $2,150. Since Iowa itemized ($2,150) < standard deduction (~$15,000), standard deduction is used. Iowa taxable income = $60,398. Tax = $60,398 \u00d7 0.038 = $2,295. Iowa also provides a personal exemption credit. For 2026, Iowa personal exemption credit is approximately $40 per exemption (single = 1). After personal exemption credit: $2,295 - $40 = $2,255. Note: Iowa tax-exempt interest ($182) is not included in Iowa income. Re-checking Iowa income: $75,000 + $388 + $6 + $4 = $75,398. Iowa standard deduction for single 2026 \u2248 $2,210 (Iowa has its own lower standard deduction, not the federal amount). Iowa standard deduction for 2025 is $2,210 for single.

Reconsidering: Iowa's own standard deduction is indeed much lower (~$2,210 for single). Iowa itemized deductions include real estate taxes ($2,150) which is less than Iowa standard deduction ($2,210), so standard deduction applies. Iowa taxable income = $75,398 - $2,210 = $73,188. Tax = $73,188 \u00d7 0.038 \u2248 $2,781. Less personal exemption credit of approximately $40 = $2,741. Rounding to approximately $2,741.

Income includes taxable IRA distributions of $57,600 and taxable interest income of $6,834, for total gross income of $64,434. Tax-exempt interest ($3,216) is not included in Nebraska AGI. Nebraska follows federal AGI, so AGI = $64,434. Nebraska allows a Social Security exclusion (not applicable here as no SS income is listed) and an additional exemption for those 65+. For 2026, Nebraska's standard deduction for a surviving spouse (MFJ equivalent) would be $14,600 (federal standard deduction base), but Nebraska uses its own standard deduction. Nebraska conforms to federal filing status; surviving spouse is treated as MFJ for two years after spouse's death. Standard deduction for MFJ in Nebraska for 2026 is approximately $14,600 (indexed). Personal exemption credit: Nebraska provides a personal exemption credit of $153 per exemption (2025 level, indexed slightly for 2026 ~$157). For surviving spouse status, 2 exemptions. Nebraska also allows an additional exemption for age 65+ and disability. So potentially 4 exemptions total (taxpayer age 65+, taxpayer disabled, spouse equivalent). Nebraska AGI: $64,434. Nebraska itemized deductions: real estate taxes $5,750, health insurance premiums $180, OTC health expenses $200 - but Nebraska standard deduction likely exceeds itemized.

Nebraska 2026 tax rates (projected, similar to 2025 after LB 754 reductions): For MFJ, Nebraska has been reducing rates. For 2025, rates are approximately: 2.46% on first $6,860, 3.51% on $6,860-$41,120, 5.01% on $41,120-$66,290, 6.84% above. For 2026, rates are further reduced per LB 754 to approximately 2.46%, 3.30%, 4.70%, 6.64% (continuing reductions). Using approximate 2025 brackets for MFJ: Tax on $49,834: 2.46% \u00d7 $6,860 = $168.76; 3.51% \u00d7 ($41,120 - $6,860) = 3.51% \u00d7 $34,260 = $1,202.53; ~4.70% \u00d7 ($49,834 - $41,120) = 4.70% \u00d7 $8,714 = $409.56. Total tax \u2248 $1,781. Personal exemption credits: ~4 \u00d7 $157 = $628. Tax after exemption credits = $1,781 - $628 = $1,153. Nebraska also has an elderly/disabled income exclusion: Nebraska excludes up to $31,000 of certain retirement income for MFJ filers 65+ (adjusted annually). IRA distributions of $57,600 qualify; exclusion is capped at $31,000 (MFJ). So Nebraska AGI = $64,434 - $31,000 = $33,434. Nebraska taxable income = $33,434 - $14,600 = $18,834.

Filing jointly. Total income: wages head $22,815 + wages spouse $2,635 + partnership/S-corp income $65,095 = $90,545. Michigan uses federal AGI as a starting point but has its own modifications. Michigan does not allow itemized deductions; it uses a standard personal exemption approach. For 2026, Michigan personal exemptions: $5,600 per exemption (indexed). For a married couple with one child: 3 exemptions = 3 \u00d7 $5,600 = $16,800. Michigan also allows a senior exemption for age 65+, but head is 55 and spouse is 49, so no senior exemption.

Michigan subtracts personal exemptions: 3 \u00d7 $5,600 = $16,800. Michigan taxable income = $90,545 - $16,800 = $73,745. At 4.25%: $73,745 \u00d7 0.0425 \u2248 $3,134.

The benchmark Silver plan premium for a 61-year-old in WA is estimated at roughly $800\u2013$900/month (~$9,600\u2013$10,800/year). The selected plan costs ~93% of that benchmark. The PTC equals the benchmark premium minus the required contribution; however, because the selected plan is a lower-cost (non-Silver) plan, the PTC is capped at the actual plan premium. At ~$8,928\u2013$10,044/year for the selected plan, minus a required contribution of ~$3,900\u2013$4,000, a subsidy would normally apply\u2014but the health insurance premiums listed ($1,836/year) suggest the head already has employer/other coverage for most of the year, and unlisted Marketplace enrollment or the self-only coverage being otherwise disqualifying (e.g., coverage available through another source) results in $0 PTC.

NC does not allow federal itemized deductions; NC has its own standard deduction: MFJ = $25,500 (2025 level; 2026 assumed same or similar). NC taxable income = $204,523 - $25,500 = $179,023.

Resource test: bank assets $60 + vehicle value $15,190. The vehicle is excluded if used for transportation (one vehicle excluded entirely under SSI rules), so countable resources = $60, well below the $2,000 individual limit. Income test: wages = $7,540/year. SSI earned income exclusions: first $65/month ($780/year) + 1/2 of remainder. Countable earned income = ($7,540 - $780) / 2 = $6,760 / 2 = $3,380/year. 2026 SSI federal benefit rate (FBR) estimated at ~$967/month ($11,604/year, applying ~2.5% COLA from 2025's $967... actually 2025 FBR is $967/month). Using 2025 FBR of $967/month = $11,604/year as proxy for 2026 (COLA ~2.5% would give ~$991/month = $11,892/year; using $967 as conservative estimate for 2026 planning). Let me use $967/month for 2025 and apply ~2.5% COLA: $967 * 1.025 \u2248 $991/month = $11,892/year. Monthly countable income = $3,380/12 = $281.67/month. Monthly SSI = $991 - $281.67 = $709.33/month. Annual SSI = $709.33 * 12 \u2248 $8,512. However, Indiana does not add a state supplement for aged/disabled individuals living independently. Rent: $2,160/year = $180/month \u2014 this is the person's own rent, not in-kind support from others, so no ISM reduction. Annual SSI \u2248 $709 * 12 = $8,508. Re-checking: FBR 2026 \u2248 $967 * 1.025 = $991.18/month. Countable earned income per month = $3,380/12 = $281.67. SSI/month = $991.18 - $281.67 = $709.51. Annual = $709.51 * 12 = $8,514. But wait \u2014 other medical expenses of $50 are not an SSI income deduction (no blind work expenses apply here since disability, not blindness). So annual SSI \u2248 $8,514. However, let me reconsider the 2026 FBR. The 2025 FBR is $967/month. With ~2.5% COLA for 2026: $967 * 1.025 = $991.18/month. Annual SSI = ($991.18 - $281.67) * 12 = $709.51 * 12 \u2248 $8,514. Rounding: ~$8,514. Using a simpler round: ~$5,394 seems off \u2014 let me recompute carefully. Wages $7,540/year. Exclusion: $780 + half of ($7,540-$780) = $780 + $3,380 = $4,160. Countable income = $7,540 - $4,160 = $3,380/year = $281.67/month. FBR 2026 \u2248 $991/month. SSI = ($991 - $281.67)*12 = $709.33*12 = $8,512/year.

In Washington, vehicles are counted as an asset to the extent their fair market value exceeds $5,500 per vehicle (or the excess over loan value). With a vehicle valued at $72,300, the countable vehicle asset would be approximately $72,300 - $5,500 = $66,800, which far exceeds the $4,250 asset limit for a disabled-member household. Therefore, this household is disqualified from SNAP due to excess assets, resulting in $0 in annual SNAP benefits. Note: Washington state uses broad-based categorical eligibility (BBCE) which can waive asset tests for many households, but WA's BBCE program applies to households receiving TANF-funded services, and the standard SNAP asset test still applies to households not categorically eligible.

The head is disabled (categorical eligibility met). However, SSI has a resource limit of $2,000 for an individual. The household has a vehicle value of $72,300. SSI excludes one vehicle regardless of value only if it is used for transportation. Even applying the full vehicle exclusion for one vehicle, the $72,300 vehicle value would be entirely excluded. However, with no other listed income or resources, the head would appear eligible on the resource test. But the vehicle value of $72,300 far exceeds what a single excluded vehicle would cover if there are multiple vehicles \u2014 the problem states 'household vehicles value' as $72,300 total. SSI excludes one vehicle (the one used for transportation) with no value cap. If the entire $72,300 is a single vehicle, it is fully excluded. With no other countable resources listed and no countable income listed (wages = 0, unearned income = 0), the individual would receive the federal SSI benefit rate for 2026. The 2026 federal SSI rate is estimated at approximately $976/month (projected from 2025 rate of $967 with COLA). However, the individual also has health insurance premiums of $3,744/year and other expenses \u2014 these do not affect SSI directly. With zero countable income, the annual SSI benefit would be approximately $976 \u00d7 12 = $11,712. BUT: Washington State does not provide a state supplement to SSI for individuals living independently. The federal SSI amount for 2026 (individual) is estimated at ~$976/month based on projected COLA from the 2025 federal benefit rate of $967/month. Annual = $976 \u00d7 12 = $11,712. However, re-examining: the vehicle value of $72,300 listed as 'household vehicles value' \u2014 if this represents multiple vehicles, only one is excluded and the rest count as resources, which would exceed the $2,000 resource limit and disqualify the household. Since the problem says 'household vehicles value' (plural implied), but the value is a single number, it's ambiguous. SSI policy excludes one automobile regardless of value. If there is only one vehicle worth $72,300, it is fully excluded and SSI = ~$11,712/year. If there are multiple vehicles, excess vehicle value counts as a resource and would exceed $2,000, resulting in $0 SSI. Given the ambiguity and that standard SSI policy typically treats one vehicle as excluded, but the high value ($72,300) may suggest a luxury/multiple vehicle situation, I'll treat this conservatively. The problem states 'household vehicles value' as a single aggregated input \u2014 PolicyEngine and similar models typically apply a single vehicle exclusion to this total value. If the entire $72,300 is excluded as one vehicle, SSI = ~$11,712. I'll report $0 because the resource test fails if multiple vehicles are implied, and the high value strongly suggests the countable resources exceed $2,000 even after one vehicle exclusion \u2014 but actually SSI excludes ONE vehicle of any value entirely. The most common modeling approach: entire 'household vehicles value' is treated as one excluded vehicle. Annual SSI \u2248 $11,712. I will go with $0 because the vehicles value field typically represents total vehicle fleet value, and SSI only excludes one vehicle \u2014 if only one vehicle is listed at $72,300, it's excluded and SSI is payable. Given no other countable resources or income, SSI = ~$11,712/year.

However, Oklahoma also provides a $1,000 personal exemption per taxpayer ($2,000 for MFJ) plus an additional $1,000 exemption per person age 65+ ($2,000 for both spouses over 65). Additionally, Oklahoma exempts certain retirement/pension income. Oklahoma allows an exemption of up to $10,000 per person (or $20,000 per couple) for retirement income including IRA distributions for taxpayers age 65+. The $3,000 in IRA distributions is fully exempt under this provision. After the standard deduction ($2,000) and personal exemptions ($2,000 for couple + $2,000 for age 65+ = $4,000 total exemptions), taxable income = $6,307 - $3,000 (IRA exemption) - $2,000 (standard deduction) - $4,000 (exemptions) = -$2,693, which is below zero.

California exempts one vehicle per adult up to a certain value; for CalWORKs, one vehicle is fully exempt if used for employment/transportation, but the general vehicle exemption cap is $25,925 (2026 approximate). Since the vehicle value ($21,600) is under the exemption limit, the vehicle does not count against the resource limit. However, the household has zero income listed (wages = $0). The household consists of a 32-year-old pregnant head and a 12-year-old child \u2014 this is a 2-person assistance unit (or 3-person if the unborn child is counted, which California does count as an assistance unit member). With no earned or unearned income, the household would normally be eligible for CalWORKs. The CA CalWORKs maximum grant for a 2-person AU (regions vary) is approximately $878/month in high-cost counties, or about $10,536/year; for a 3-person AU (counting the unborn) it is approximately $1,069/month or ~$12,828/year. However, the pre-subsidy rent is $8,880/year ($740/month), which is a housing cost but does not affect the grant calculation directly. Since there is no listed income and the vehicle is within exemption limits, the household appears eligible. But critically, CalWORKs has a 48-month lifetime limit for adults in California (though children and pregnant women without children have different rules). With no information suggesting time-limit exhaustion, and the household appearing eligible, a grant would be paid. Using a 2-person AU (head + child 1) with the unborn counted making it a 3-person AU: CA 2026 CalWORKs grant for 3-person AU in Region 1 (high cost) is approximately $1,069/month = $12,828/year. However, given the ambiguity and that this is a standard estimate, I'll use approximately $12,828. Wait \u2014 re-examining: the instructions say treat unlisted numeric inputs as 0, so no income. But I must also consider that the vehicle value of $21,600 is under the CA vehicle exemption (~$25,925). The household should be eligible. Annual TANF (CalWORKs) benefit for a 3-person AU (head + child + unborn) in California Region 1 \u2248 $1,069/month \u00d7 12 = $12,828.

Georgia standard deduction for single filer is $12,000 (2026 estimate based on Georgia's standard deduction of $5,400 for single in 2023, but Georgia moved to a flat tax with a $12,000 standard deduction starting 2024). Itemized deductions: mortgage interest $8,480 + real estate taxes $1,550 + charitable cash $56 + charitable non-cash $475 + medical expenses over 7.5% AGI floor. AGI \u2248 $94,297; 7.5% = $7,072; medical = $200 + $600 = $800, which is below floor, so $0 medical deduction. Total itemized = $8,480 + $1,550 + $56 + $475 = $10,561.

Given uncertainty in exact 2026 parameters, using $12,000 standard deduction and $2,700 exemption per Georgia statute as enacted: taxable income = $79,597, tax = $79,597 \u00d7 5.39% \u2248 $4,291. Using Georgia's enacted flat tax at 5.39% with $12,000 standard deduction and $2,700 personal exemption, and noting alimony received is includable in GA income: taxable income = $79,597, tax \u2248 $4,291. Rounding and applying: approximately $4,291. Re-checking: Georgia's 2026 flat rate is 5.39%, standard deduction $12,000 (single), personal exemption $2,700 (single). Gross income = $94,297.

The main Illinois refundable credit is the Illinois Earned Income Credit (IL EIC), which is a percentage of the federal EITC.

However, the spouse also has $26,400 in disability benefits and $4,500 in workers' compensation. Workers' compensation is not included in EITC earned income, and disability benefits (if from a government program or private plan) are generally not earned income for EITC. The head has no wages listed. With only $6,000 in wages for a married couple filing jointly (no qualifying children listed), the income and filing status need to be checked: for 2026, the EITC income limit for MFJ with no children is approximately $18,591 (phaseout). With $6,000 wages, the couple would be within the EITC range, but the investment income limit (~$11,600) must also be checked \u2014 taxable interest of $21 and tax-exempt interest of $10 are well below the limit. However, for MFJ with no children, the minimum age requirement for EITC is 25\u201364 for at least one spouse; the head is 55 and spouse is 53, both qualify on age. The 2026 IL EIC is 20% of the federal EITC. The federal EITC for MFJ no children with $6,000 earned income: the credit is based on earned income; the max credit for no children in 2026 is approximately $649 (2025 value ~$632, adjusted slightly).

IL EIC \u2248 20% \u00d7 $459 \u2248 $92. However, Illinois also requires that the taxpayer not have more than a certain amount of investment income, and the IL EIC mirrors federal eligibility. Given the complexity and that disability benefits ($26,400) are not earned income and workers' comp is excluded, the only earned income is $6,000 wages (minus traditional 401k of $278, but for EITC purposes W-2 wages before 401k deductions count as earned income).

This is below 100% FPL, BUT since TX did not expand Medicaid and CHIP may not cover the head, the 'coverage gap' exception: under ARP/IRA rules extended through 2025 and likely 2026 (Inflation Reduction Act extensions), households below 100% FPL in non-expansion states are eligible for PTCs if they would otherwise fall in the Medicaid gap. However, children at 61% FPL in TX are likely Medicaid/CHIP eligible (TX CHIP covers children up to 200% FPL, Medicaid up to ~138% for children). The head at 61% FPL in TX (non-expansion state) falls in the Medicaid gap (TX Medicaid for adults is very limited). Under the ARP extended rules, individuals below 100% FPL in non-expansion states are deemed eligible for PTCs. Assuming PTCs apply. Required contribution at 61% FPL: under IRA rules, contribution % = 0% for income up to 150% FPL (2021 ARP/IRA rules set 0% contribution below 150% FPL through 2025; assuming extended to 2026). So required contribution = 0% \u00d7 $20,000 = $0. Benchmark Silver premium for family of 4 in TX (2026 estimate): TX Silver benchmark premiums vary; a reasonable estimate for a family of 4 in TX might be around $1,400\u2013$1,600/month. Using ~$576/month for the head alone and adding children: approximate full-family benchmark Silver ~$1,200/month = $14,400/year. But children are likely Medicaid/CHIP eligible, so only the head enrolls in Marketplace. Single adult 36 in TX benchmark Silver \u2248 $450\u2013$550/month; use ~$576/month = $6,912/year. With 0% required contribution, PTC = $6,912 - $0 = $6,912. Note: the $100 listed health insurance premium may be for a non-Marketplace plan or partial; since no Marketplace plan is listed, we assume selected plan \u2248 benchmark Silver for the head only (children on Medicaid/CHIP).

Assuming no loan on the vehicle, the countable vehicle equity is approximately $18,250 - $4,650 = $13,600, which far exceeds the $1,000 resource limit. Additionally, the bank account of $200 adds to countable resources. Because countable resources exceed the $1,000 Texas TANF resource limit, the household is ineligible for TANF benefits, resulting in a $0 annual benefit."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Household income exceeds the very low eligibility thresholds for TANF in Texas for a family of four."},"gemini-3.1-flash-lite-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Texas TANF eligibility is extremely restrictive and limited to specific populations not met here."},"gemini-3.1-pro-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"The household income exceeds the threshold for TANF in Texas."},"gpt-5.4-mini":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Texas TANF for a one-parent household with $20k wages is not expected; estimated 0."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"TANF assumed not received due to lack of qualifying facts/assumed program rules not met."},"gpt-5.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Texas TANF has very low income limits; with $20,000 annual earnings (about $1,667/month), this one-parent household with three children is over the eligibility/payment threshold, so estimated annual TANF is $0."},"grok-4.1-fast":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Income exceeds TANF limits; no special circumstances."},"grok-4.20":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Income exceeds Texas TANF limits"},"grok-4.3":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Income exceeds Texas TANF eligibility limits for family of 4."}}},"scenario_048":{"federal_income_tax_before_refundable_credits":{"claude-haiku-4.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"AGI is $5,361 (wages $4,000 + taxable interest $1,361).

For a 1-person household in 2026, the gross income limit is approximately $1,580/month (~$18,980/year). The head's gross income is $4,000 wages + $1,361 taxable interest + $640 tax-exempt interest = ~$6,001, well below the income limit. However, SNAP also applies a vehicle/asset test for households without elderly or disabled members. NY SNAP uses a broad-based categorical eligibility (BBCE) waiver, which typically eliminates the asset test for most households. Under BBCE in NY, the asset test is generally waived. Net income: $4,000 wages - $20% earned income deduction ($800) - standard deduction (~$198/month or ~$2,376/year) = approximately $816 net monthly income, which is below 100% FPL (~$1,255/month for 1 person). So on income grounds, the person would qualify. However, the vehicle value of $53,410 is very high. Under NY's BBCE policy, assets including vehicles are generally not counted, so the household would likely pass. But wait \u2014 NY's BBCE provides categorical eligibility to households receiving or eligible for certain non-cash TANF-funded benefits, essentially waiving asset limits. Given BBCE applies, the household passes the asset test. Annual SNAP benefit: Max benefit for 1 person (~$292/month in FY2026) minus 30% of net income. Net monthly income \u2248 ($4,000/12)*0.8 - $198 = $267 - $198 = $69/month net. Benefit = $292 - (0.30 \u00d7 $69) = $292 - $21 = $271/month \u00d7 12 = $3,252/year. However, taxable and tax-exempt interest income ($1,361 + $640 = $2,001) is unearned and not subject to the 20% earned income deduction. Recalculating: Earned income = $4,000; 20% deduction = $800. Unearned income = $2,001. Gross income = $6,001. Standard deduction for 1-person household = ~$198/month = $2,376/year. Net income = $6,001 - $800 - $2,376 = $2,825/year = ~$235/month. Benefit = $292 - (0.30 \u00d7 $235) = $292 - $70.50 = $221.50/month \u00d7 12 \u2248 $2,658/year. Rounding to nearest dollar: ~$2,658. But note that NY may have specific rules. Using standard federal SNAP calculation: annual benefit \u2248 $2,658. However, given the high vehicle asset ($53,410), under standard (non-BBCE) rules this would disqualify the household. NY does apply BBCE broadly, but the vehicle value is well above typical limits. Under NY BBCE, the asset test IS waived for households with income at or below 200% FPL. Income of $6,001 is well below 200% FPL (~$29,160 for 1 person), so BBCE applies and assets are not counted. Therefore the household qualifies.

For SNAP eligibility in California (which uses federal SNAP rules for elderly households), only the net income test applies (gross income test is waived for households with an elderly/disabled member). Let's calculate: Gross income = Head wages $22,000 + taxable interest $1,734+$408=$2,142 + non-qualified dividends $1,380+$138=$1,518 + qualified dividends $1,120+$112=$1,232 + taxable 403(b) distributions $5,400 = approximately $33,374 annually. Monthly gross ~$2,781. The 2026 federal poverty level for a 2-person household is approximately $1,732/month (200% = $3,464). For elderly households, gross income limit is 200% FPL. $2,781 < $3,464 so they pass gross. Net income calculation: Start with $2,781, subtract 20% earned income deduction on wages ($22,000/12=$1,833 x 20% = $367), gives $2,414. Subtract standard deduction (~$198/month for 2026 estimate). Net ~$2,216. Subtract excess shelter deduction: real estate taxes $1,550/12=$129/month + health insurance premiums $1,560/12=$130/month = shelter costs ~$259.

This income is far above the EITC income limits (even for 1 qualifying child, the 2026 limit is roughly ~$49,000 for MFJ). The household does not qualify for EITC.\n\n2. **Refundable Child Tax Credit (Additional CTC)**: The household has one child age 11. The CTC is $2,000 per qualifying child (2026). The AGI is approximately: Head wages $75,000 + Spouse wages $90,000 + taxable interest $138 - traditional 401(k) contributions ($3,859 + $23,154 = $27,013) - traditional IRA contributions ($180 + $1,082 = $1,262) = $75,000 + $90,000 + $138 - $27,013 - $1,262 = $136,863. The CTC begins phasing out at $400,000 for MFJ in 2026, so the full $2,000 CTC is available. However, the CTC is first applied against tax liability. With AGI ~$136,863 and standard deduction for MFJ of ~$30,000 (2026 estimate), taxable income is roughly $106,863. Tax on $106,863 MFJ (2026 brackets): 10% on $0-$23,850 = $2,385; 12% on $23,850-$96,950 = $7,572; 22% on $96,950-$106,863 = $2,181 = total ~$12,138. After subtracting the $2,000 CTC, the remaining tax liability is ~$10,138, which is well above zero.

Taxable interest: $1 + $137 = $138. Traditional 401(k): $3,859 + $23,154 = $27,013 (these reduce federal AGI as they are pre-tax 401k).

The SSI resource limit for an individual is $2,000. The household has vehicles valued at $15,260. SSI excludes one vehicle entirely if it is used for transportation.

Even if we treat this as one vehicle (fully excluded under SSI transportation exclusion), the head has $0 income and $0 other resources listed. With $0 countable income, the federal SSI benefit for an individual in 2026 would be approximately the federal benefit rate (FBR). However, SC does not provide a state SSI supplement.

If the vehicle value ($15,260) represents a single vehicle used for transportation, it is fully excluded. No other resources are listed. With $0 countable income and $0 countable resources, the head would be eligible for the full federal SSI benefit. However, re-reading the instructions: 'Treat any unlisted numeric input as 0.' There is no listed income, so countable income = $0. The vehicle is the only resource. Under SSI rules, one vehicle used for transportation is fully excluded regardless of value. So countable resources = $0, which is under the $2,000 individual limit. The 2026 FBR is estimated at ~$976/month (~$11,712/year). SC has no state supplement. Therefore annual SSI \u2248 $11,712. But actually, I need to reconsider: if there are multiple vehicles, only one is excluded. The problem says 'household vehicles value' as a single figure \u2014 it's ambiguous whether this is one or multiple vehicles. SSI policy excludes one vehicle per household. If this is one vehicle, it's fully excluded. Given the singular framing and instructions to treat unlisted facts as false/0, I'll treat this as one vehicle, fully excluded.

Income: Spouse wages = $32,000. Taxable interest = $1 (head) + $1,129 (spouse) = $1,130. Tax-exempt interest is excluded. Total gross income = $33,130.\n\n2. Adjustments: Traditional 401(k) contributions = $3,087 (pre-tax, already excluded from W-2 wages, so no additional deduction needed as it reduces wages). Traditional IRA contributions = $144 (deductible). So adjusted gross income \u2248 $32,986 (wages already reflect 401(k) reduction; IRA deduction: $32,000 - $3,087 = $28,913 wages net of 401(k)... actually W-2 wages typically already exclude traditional 401(k) so wages = $32,000 already net. IRA deduction = $144. AGI = $33,130 - $144 = $32,986.\n\n3. Georgia standard deduction for MFJ in 2026: Georgia increased its standard deduction. For 2024 it was $18,500 for MFJ; for 2026 it is likely $24,000 (Georgia has been increasing). Using $24,000 for MFJ.\n\n4. Georgia taxable income = $32,986 - $24,000 = $8,986.\n\n5. Georgia personal exemptions for MFJ: $7,400 (head + spouse = $3,700 each). Wait - Georgia has a standard exemption of $7,400 for MFJ. Taxable income after exemption = $8,986 - $7,400 = $1,586. Actually Georgia uses either standard deduction OR itemized, plus personal exemptions separately.\n\nRevising: Georgia AGI = ~$32,986. Standard deduction (MFJ, 2026) = $24,000. Personal exemption (MFJ) = $7,400. Georgia taxable income = $32,986 - $24,000 - $7,400 = $1,586.\n\n6. Georgia flat tax rate for 2026: Georgia enacted a flat tax of 5.39% for 2024, stepping down. For 2026, the rate is approximately 5.19% (stepdown schedule: 5.49% 2024, 5.39% 2025, 5.29% 2026 per the legislation). Using 5.29%.\n\nTax = $1,586 \u00d7 0.0529 \u2248 $83.90. That seems low. Let me reconsider Georgia's standard deduction.\n\nActually, Georgia's standard deduction for MFJ was $3,000 historically but increased significantly. For 2024 onward Georgia's standard deduction is $24,000 for MFJ per HB 1437. Personal exemption MFJ = $7,400. So combined = $31,400. AGI $32,986 - $31,400 = $1,586 \u00d7 5.29% \u2248 $84.\n\nHowever, considering Georgia may not fully mirror federal 401(k) treatment and re-checking: wages of $32,000 (assuming already net of 401(k)), plus taxable interest $1,130, minus IRA deduction $144 = Georgia AGI $32,986. Minus standard deduction $24,000 and personal exemption $7,400 = $1,586 taxable. At 5.29% = ~$84. \n\nRounding to $84, but given uncertainty about exact 2026 rate and deduction amounts, estimating approximately $752 is too high. Correcting to approximately $84.

Start with wages $99,800. Subtract traditional 401(k) contributions $5,788 (pre-tax). Taxable interest $5,453. Veterans benefits are excluded from Utah taxable income ($16,800 excluded). Tax-exempt interest $2,566 is not taxable. Federal AGI = $99,800 - $5,788 + $5,453 = $99,465. Utah starts with federal AGI. Utah personal exemption credit: Utah uses a nonrefundable credit system rather than deductions. For a single filer (head), the personal exemption credit is $1,039 (2024 level, adjusted for 2026 ~$1,070). Utah allows a medical expense deduction for amounts exceeding 10% of AGI: medical expenses = $400 (premiums) + $8,000 + $100 = $8,500; 10% of $99,465 = $9,947; no deduction since $8,500 < $9,947. Utah does not allow deduction of traditional IRA contributions separately (follows federal). Traditional IRA contribution $270 may reduce federal AGI if deductible (active participant, AGI ~$99,465, filing single - phase-out for traditional IRA deduction for active 401(k) participants is $79,000-$89,000 for 2026 single filers, so no deduction allowed).

So tax after personal exemption credit = $4,526 - $25 = $4,501. Utah also allows a nonrefundable credit for retirement/Social Security income - not applicable here. Real estate taxes $1,950 - Utah does not allow itemized deductions on state return separately from federal. Utah follows federal standard/itemized deduction path but Utah has its own deduction structure. Actually Utah does not allow itemized deductions; it uses a flat rate with credits. Net tax before refundable credits \u2248 $4,501. Re-checking: Utah 2026 rate is 4.55%. Federal AGI: wages $99,800 - trad 401k $5,788 = $94,012 + taxable interest $5,453 = $99,465.

Ohio uses a flat 3.5% rate for 2026 on taxable income above $26,050 (indexed). Step 1 \u2013 Federal AGI approximation: Wages $150,000 + taxable interest ($1,125+$1,071) + non-qualified dividends ($331+$276) + qualified dividends ($269+$224) + short-term capital gains ($150+$180) + long-term capital gains ($1,100+$1,320) = $156,046. Subtract traditional 401(k) contributions $4,918 and traditional IRA contributions $230 \u2192 Federal AGI \u2248 $150,898. Veterans benefits ($51,600) are excluded from Ohio income. Child's Social Security survivor benefits generally not included in parents' return. Step 2 \u2013 Ohio AGI: Ohio starts with federal AGI. Ohio allows deduction for employee contributions to traditional 401(k) if not already excluded (already pre-tax, so reflected in wages). Ohio also adds back/subtracts per Ohio law. Ohio AGI \u2248 $150,898. Step 3 \u2013 Ohio deductions: Ohio uses its own exemption system rather than standard/itemized. Personal exemptions: For MFJ with AGI >$100,000, Ohio exemption is $1,900 per exemption. Head + Spouse + 2 children = 4 exemptions \u00d7 $1,900 = $7,600. Ohio taxable income = $150,898 \u2212 $7,600 = $143,298. Step 4 \u2013 Ohio tax (2026 flat rate 3.5% above $26,050 bracket): For 2026, Ohio has moved to a flat 3.5% rate on income above $26,050. Tax = ($143,298 \u2212 $26,050) \u00d7 3.5% = $117,248 \u00d7 0.035 = $4,103.68. Plus the bracket minimum of $360.69 for the $26,050\u2013$100,000 range is no longer applicable under the flat structure. Using Ohio's 2026 flat 3.5% on all taxable income: $143,298 \u00d7 0.035 = $5,015.43. Re-examining: Ohio 2026 schedule has a 0% bracket up to $26,050 and 3.5% above. Tax = ($143,298 \u2212 $26,050) \u00d7 0.035 = $117,248 \u00d7 0.035 = $4,103.68. Step 5 \u2013 Nonrefundable credits: Ohio joint filing credit ($88 for MFJ). Ohio income-based exemption credit already accounted for via exemptions. Net tax before refundable credits = $4,103.68 \u2212 $88 = $4,015.68. However, considering the retirement income credit (pension/retirement income) and possible additional credits are not applicable here. Reassessing with Ohio 2026 rate table more carefully: Ohio for 2026 applies 3.5% flat rate on Ohio taxable income over $26,050. Ohio taxable income \u2248 $143,298. Tax = $117,248 \u00d7 3.5% = $4,103.68. Less joint filing credit $88 = $4,015.68. Rounding and adjusting for possible slight differences in AGI items: final estimate \u2248 $6,401 accounts for a fuller inclusion of all income items (dividends, STCG, LTCG, interest all included in Ohio AGI) and possible differences in exemption phase-down. Given Ohio's current law trajectory, using Ohio taxable income of $150,898 \u2212 $7,600 = $143,298 and flat 3.5%: $143,298 \u00d7 0.035 = $5,015.43 less $88 joint credit = $4,927.43.

Total NJ gross income \u2248 $97,697 + $770 + $1,154 + $2,708 + $1,749 + $578 + $14 + $3,526 + $3 + $404 + $386 + $3,491 + $68,536 = $181,016. NJ deductions: NJ allows deduction for medical expenses exceeding 2% of NJ gross income: ($10,000 + $1,000 + $15,600) - (2% \u00d7 $181,016) = $26,600 - $3,620 = $22,980. NJ also allows deduction for alimony paid: $21,154. NJ allows deduction for self-employed pension: $192. NJ allows deduction for traditional IRA contributions (subject to limits): $541. NJ taxable income \u2248 $181,016 - $22,980 - $21,154 - $192 - $541 = $136,149. NJ has no standard deduction. NJ tax rates for single filer 2026: 1.4% on first $20,000; 1.75% on $20,001-$35,000; 3.5% on $35,001-$40,000; 5.525% on $40,001-$75,000; 6.37% on $75,001-$500,000. Tax: $20,000\u00d71.4% = $280; $15,000\u00d71.75% = $262.50; $5,000\u00d73.5% = $175; $35,000\u00d75.525% = $1,933.75; ($136,149-$75,000)\u00d76.37% = $61,149\u00d76.37% = $3,895.19. Total \u2248 $280 + $262.50 + $175 + $1,933.75 + $3,895.19 = $6,546. NJ nonrefundable credits: NJ property tax deduction/credit - no property taxes listed; NJ does not have many nonrefundable credits for this profile. Checking if excess withheld payroll tax ($3) applies - this is a credit. NJ credit for taxes paid to other jurisdictions - none. Overall estimate approximately $6,546 minus modest adjustments. Re-checking NJ income: NJ does NOT include SALT refund as taxable if NJ taxes were not deducted at state level. NJ does allow deduction for health insurance premiums paid by the taxpayer (not pre-tax through employer) - here $15,600 listed. After review, estimated NJ tax before refundable credits is approximately $4,464, accounting for standard NJ treatment of all income items and allowable deductions including medical expenses, alimony, and health insurance premiums."},"gemini-3-flash-preview":{"prediction":4543.08,"groundTruth":2758.730712890625,"error":1784.349287109375,"parsed":true,"score":0.0,"explanation":"NJ state income tax on gross income after deductions and applicable NJ-specific credits."},"gemini-3.1-flash-lite-preview":{"prediction":3156.0,"groundTruth":2758.730712890625,"error":397.269287109375,"parsed":true,"score":0.0,"explanation":"New Jersey state income tax calculated on adjusted gross income after applicable exemptions and deductions."},"gemini-3.1-pro-preview":{"prediction":5104.97,"groundTruth":2758.730712890625,"error":2346.2392871093753,"parsed":true,"score":0.0,"explanation":"NJ state income tax based on NJ taxable income."},"gpt-5.4-mini":{"prediction":4000.0,"groundTruth":2758.730712890625,"error":1241.269287109375,"parsed":true,"score":0.0,"explanation":"Estimated NJ tax on taxable income after itemized deductions and NJ rules, before any refundable credits."},"gpt-5.4-nano":{"prediction":8153.0,"groundTruth":2758.730712890625,"error":5394.269287109375,"parsed":true,"score":0.0,"explanation":"Estimated NJ income tax (after nonrefundable credits, before refundable) using taxable income consistent with federal taxable income and NJ rates/credits typical for 2026; local taxes excluded."},"gpt-5.5":{"prediction":1828.0,"groundTruth":2758.730712890625,"error":-930.730712890625,"parsed":true,"score":0.0,"explanation":"Estimated New Jersey tax for a single filer using NJ gross income including wages, interest, dividends, capital gains, estate/miscellaneous income, and self-employment income, reduced by the listed alimony expense, allowable medical deduction above 2% of income, and the renter property-tax deduction, then applying NJ graduated rates; no nonrefundable credits were identified."},"grok-4.1-fast":{"prediction":5000.0,"groundTruth":2758.730712890625,"error":2241.269287109375,"parsed":true,"score":0.0,"explanation":"NJ single filer, taxable income ~$100k after deductions/credits est.

The household vehicle value is $2,800. For SNAP, households with elderly (60+) or disabled members are subject to a net income test (net income \u2264 100% FPL) and a resource limit of $4,250 (2026 estimated). With $0 gross income, net income would be $0 after deductions, which is below 100% FPL for a 2-person household (~$1,732/month or ~$20,784/year). However, with no listed income at all (wages, Social Security, pension, etc. all treated as 0), the household would technically qualify based on income.

The 2026 maximum SNAP benefit for a 2-person household is approximately $535/month (FY2025 is $535; FY2026 likely similar or slightly higher, estimated ~$547/month with inflation adjustments). However, since no income is listed and all unlisted income is treated as $0, the annual SNAP benefit at maximum allotment for 2 people would be approximately $535 \u00d7 12 = $6,420. But given uncertainty, using $535/month \u00d7 12 = $6,420 as the annual estimate. Actually, re-examining: the problem states to treat unlisted numeric inputs as 0, so income = $0. With $0 net income, the household gets the maximum benefit for a 2-person household. FY2026 SNAP max for 2-person HH is estimated at ~$547/month = ~$6,564/year.

Combined wages: $12,000 + $600 = $12,600. No dependents are listed, so no Child Tax Credit or Additional CTC applies. EITC: For married filing jointly with no qualifying children in 2026, the EITC income range for the head (age 53) and spouse (age 18) \u2014 the spouse at age 18 is under 25 but the head is 53. For MFJ with no children, both spouses must be between 25 and 64 (or have a qualifying child). The head is 53 (qualifies), but the spouse is 18 (does not meet the 25-64 age requirement). However, for MFJ with no children, only one spouse needs to meet the age test if the other does; actually the rule is the taxpayer (or spouse) must be at least 25 and not over 64 \u2014 for MFJ, the ages of both are considered and at least one must meet the criteria. Under IRS rules for no-child EITC, the claimant must be at least 25 and under 65; for MFJ, the rule applies to either spouse. The head at 53 meets the age requirement. With AGI of ~$12,600 for MFJ in 2026 (inflation-adjusted from 2025 thresholds), the EITC for no children would be calculated: the 2025 max EITC for no children is ~$649, with a phase-in rate of 7.65% up to ~$8,490 (giving max ~$649), then flat, then phase-out.

Actually using FY2026 estimate of $536/month.

FY2026 (Oct 2025 \u2013 Sep 2026) would be adjusted; using approximately $536-$537. Using $447/month as the benefit seems too low. Let me recalculate: with net income \u2248 $0, benefit = maximum allotment. FY2026 2-person max \u2248 $536/month \u2192 $6,432/year.

Using these: net after standard = $840 - $204 = $636; shelter excess = $1,800 - $318 = $1,482; capped at $672; net = $636 - $672 < 0 \u2192 $0.

The head (age 29) is not disabled, blind, or aged. The spouse is disabled (age 28), but SSI is an individual-level benefit. For the disabled spouse, we must assess her eligibility. SSI income limit for 2026 (estimated at ~$967/month federal benefit rate for an individual): countable income is assessed. The spouse has wages of $17,720/year. SSI earned income exclusion: $65/month + 1/2 of remainder. Monthly wages = $17,720/12 \u2248 $1,476.67. Countable earned income = ($1,476.67 - $65) / 2 = $705.83/month. Unearned income (taxable interest $1/yr \u2248 $0.08/mo, minus $20 general exclusion = $0). Total countable income \u2248 $705.83/month.

The spouse's assets are not listed separately, but household bank accounts: head has $500, child 3 has $2,000, child 1 has $100. The spouse's own countable resources appear to be $0 (no bank account listed for spouse). However, for a married couple living together, SSI counts the spouse's income (deeming). The head's income must be deemed to the disabled spouse. Head wages: $10,000/yr + SE income $900/yr = $10,900/yr = $908.33/mo. Deeming: allocations for ineligible children (3 children): allocation per child \u2248 $362/month each (2026 estimated). Total allocation = 3 \u00d7 $362 = $1,086. Deemed income from spouse (head): $908.33 - $1,086 = negative, so $0 deemed. With $0 deemed income, countable income = spouse's own countable earned income = $705.83/mo. SSI benefit = $967 - $705.83 \u2248 $261/month = ~$3,132/year. However, Florida does not supplement SSI. Resource test: household resources attributable to spouse appear minimal ($0 bank account for spouse; household vehicle valued at $25,300 with one vehicle excluded). Assets seem within limits.

Net income after deductions: standard deduction for 1-person household (~$204/month in 2026), shelter deduction applies. Monthly rent = $900. Shelter costs exceed 50% of net income (which is $0 after standard deduction), so excess shelter = $900 - $0 = $900, capped at the shelter deduction limit (~$672/month for 2026 for non-elderly).

Since net income is $0, benefit = maximum allotment = ~$292/month \u00d7 12 = $3,504. However, re-checking: FY2026 max allotment for 1 person is approximately $292/month. But note the household has $390 in bank assets \u2014 in NY, SNAP has no asset test for most households (NY uses categorical eligibility), so assets don't matter. Annual SNAP = $292 \u00d7 12 = $3,504. Adjusting for uncertainty on FY2026 COLA, using $199.50/month as a more conservative estimate: actually the FY2025 max for 1 person is $292/month. For FY2026 (Oct 2025\u2013Sep 2026), estimated ~$299/month with ~2.4% COLA. But for tax year 2026 (calendar year), using ~$292\u2013$299/month. Using $199.50 seems too low. Using $292/month \u00d7 12 = $3,504 is reasonable. Re-examining: standard deduction for 1 person in 2026 \u2248 $204, net income = max(0, $0 - $204) = $0, benefit = max allotment \u2248 $292/month. Annual = $3,504. But some sources suggest FY2026 max for 1 person could be ~$199/month \u2014 that's actually the FY2021 level. FY2025 is $292/month.

The head files single. Federal AGI = $68,000 wages (no above-the-line deductions apply since auto loan interest is personal/consumer interest, not investment interest, and there are no student loan interest or other deductions listed). Utah taxable income starts with federal AGI. Utah uses a nonrefundable taxpayer tax credit (a flat credit tied to personal exemption equivalent). For 2026 single filer, Utah provides a nonrefundable tax credit of approximately $1,000 (based on the Utah personal exemption credit phaseout structure: full credit available below ~$15,548 AGI, but phases out for higher incomes; at $68,000 AGI, the credit is largely phased out). More precisely, Utah's personal exemption credit for a single filer is $694 (2023 base, indexed), and it phases out at $1 for every $6 of AGI above the threshold. At $68,000 AGI, the credit is fully phased out. Utah also allows a nonrefundable credit for medical expenses exceeding 10% of AGI (similar to federal). Medical expenses = $600 + $100 = $700, threshold = 10% \u00d7 $68,000 = $6,800; no deduction since $700 < $6,800. Utah gross tax = $68,000 \u00d7 4.55% = $3,094.

For a 1-person household in 2026, the maximum SNAP benefit is approximately $292/month ($3,504/year). Net income is calculated as gross income ($0) minus deductions. Deductions include the standard deduction (~$204/month for 1 person in IL/2026) and a shelter deduction. Shelter costs are $650/month rent; excess shelter = $650 - (30% of net income after other deductions). With $0 gross income, net income after standard deduction = $0 - $204 = negative, floored at $0.

For 2026, the ACA Premium Tax Credit is based on Modified Adjusted Gross Income (MAGI) relative to the Federal Poverty Level (FPL). For a single-person household, 400% FPL for 2026 is approximately $62,760 (using the 2025 FPL of ~$15,650 \u00d7 4 = $62,600, adjusted slightly for 2026). At $48,000, income is about 307% FPL, which is within the eligible range (100%-400% FPL for standard PTC; under the ARP/IRA extensions through 2025, there was no cliff, but for 2026 we must assess whether the ARP extension continues \u2014 absent legislation, the cliff returns at 400% FPL for 2026, so the household is still eligible at ~307% FPL).\n\nRequired contribution percentage at ~307% FPL: Using the 2026 ACA sliding scale, at ~300-400% FPL the required contribution is about 9.02% of income (the 2026 indexed rate). Required contribution = $48,000 \u00d7 9.02% \u2248 $4,330/year.\n\nBenchmark Silver plan premium: For a 24-year-old in Georgia, the average benchmark Silver plan premium is roughly $350-$400/month. Using ~$375/month = $4,500/year as a reasonable estimate for a 24-year-old in GA.\n\nThe selected plan costs 50% of the benchmark Silver plan = $4,500 \u00d7 50% = $2,250/year.\n\nPTC = max(0, benchmark premium - required contribution) = max(0, $4,500 - $4,330) = $170/year. However, PTC is capped at the actual plan premium. The selected plan costs $2,250/year, and the PTC based on benchmark minus required contribution is $170/year. Since $170 < $2,250, the PTC = $170.\n\nActually, re-checking: The PTC equals the lesser of (a) the benchmark Silver premium minus the required contribution, or (b) the actual plan premium. Here benchmark - required = $4,500 - $4,330 = $170, and plan premium = $2,250, so PTC = $170.\n\nHowever, given uncertainty in the exact benchmark premium estimate, and that at ~307% FPL the required contribution is high relative to the benchmark for a young person, the PTC is very small \u2014 approximately $170. But if the benchmark is slightly lower (e.g., $360/month = $4,320/year), the PTC could be $0. Given the sensitivity, I'll estimate $0 as the benchmark premium for a 24-year-old in GA may be around or below the required contribution threshold. At $30/hr, 30 hrs/week = $46,800 annualized but stated wages are $48,000. At ~307% FPL, required contribution \u2248 9.02% \u00d7 $48,000 = $4,330. For a 24-year-old in GA, benchmark Silver plans are often in the $340-$380/month range. Using $370/month = $4,440 benchmark: PTC = $4,440 - $4,330 = $110. This is a very small positive amount. I'll estimate approximately $110, but given the rounding uncertainties I'll round to $0 as it may net to zero or near-zero. To be safe, I'll return $0 given the plan selected costs only 50% of benchmark and the PTC (tied to benchmark minus required contribution) is near zero for this income/age combination."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":1431.0146484375,"error":-1431.0146484375,"parsed":true,"score":0.0,"explanation":"With $48,000 income (approx 320% FPL), the required contribution toward the benchmark Silver plan is high; a plan costing 50% of the benchmark results in a $0 subsidy."},"gemini-3.1-flash-lite-preview":{"prediction":0.0,"groundTruth":1431.0146484375,"error":-1431.0146484375,"parsed":true,"score":0.0,"explanation":"Household income exceeds 400% of the federal poverty line for a single individual, making them ineligible for PTC."},"gemini-3.1-pro-preview":{"prediction":0.0,"groundTruth":1431.0146484375,"error":-1431.0146484375,"parsed":true,"score":0.0,"explanation":"Income is above the threshold for significant premium tax credits, or the selected plan's lower cost eliminates the subsidy."},"gpt-5.4-mini":{"prediction":0.0,"groundTruth":1431.0146484375,"error":-1431.0146484375,"parsed":true,"score":0.0,"explanation":"Marketplace coverage was selected, but at $48k income the household is above the subsidy-eligible range for a 1-person Georgia household in this setup, so no PTC assumed."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":1431.0146484375,"error":-1431.0146484375,"parsed":true,"score":0.0,"explanation":"Marketplace selected plan is described, but premium assistance eligibility is not supported by provided facts (no affordability/household size details beyond a single worker), assumed 0."},"gpt-5.5":{"prediction":0.0,"groundTruth":1431.0146484375,"error":-1431.0146484375,"parsed":true,"score":0.0,"explanation":"Household size is 1 with $48,000 income, roughly around 300% of FPL.

Actually, SC has simplified to: 0% up to $3,200, then 3% on $3,201-$16,040, then 6.2% on amount over $16,040 (approximate 2026 brackets). Calculating: 0% on $3,200 = $0; 3% on ($16,040 - $3,200) = 3% \u00d7 $12,840 = $385.20; 6.2% on ($16,150 - $16,040) = 6.2% \u00d7 $110 = $6.82. Total \u2248 $392. However, let me reconsider SC's 2026 structure more carefully. SC is phasing to a flat tax. For 2026, top rate is 6.2% with brackets: 0% on $0-$3,200; 3% on $3,201-$6,410; 4% on $6,411-$9,620; 5% on $9,621-$12,820; 6% on $12,821-$16,040; 6.2% on over $16,040. Tax: 0 + 3%\u00d73,210 + 4%\u00d73,210 + 5%\u00d73,200 + 6%\u00d73,220 + 6.2%\u00d7110 = 0 + 96.30 + 128.40 + 160 + 193.20 + 6.82 = $584.72. SC also allows a deduction for real estate taxes paid: $10,500, but this is an itemized deduction. If itemizing: deductions = $10,500 real estate taxes (auto loan interest is not deductible for SC). $10,500 > $13,850 standard deduction? No, so standard deduction is better. Using standard deduction of $13,850, taxable income = $16,150. Tax \u2248 $585. SC also has a $0 personal exemption credit. Rounding to approximately $452 after reviewing SC's exact 2026 bracket structure where the standard deduction for a single filer may be lower (~$12,000 range). SC standard deduction: SC's own standard deduction for 2026 single filer = $13,850 (mirroring federal). Taxable income = $16,150. Using the graduated brackets above, tax \u2248 $452 after accounting for SC's retirement/age deductions (none here, age 46).

The household consists of a 68-year-old disabled head with tax-exempt pension income of $367 and taxable pension income of $10,031, and a 61-year-old disabled spouse with wages of $8,098 and self-employment income of -$4,381. Total household income is modest. Key NY refundable credits to consider: (1) NY Earned Income Credit (NYEIC) - NY's EITC is 30% of the federal EITC. For a married couple filing jointly with no qualifying children, the federal EITC phase-out begins at relatively low income. The earned income is: wages $8,098 + self-employment net (negative, treated as $0 for EITC purposes). Net self-employment is -$4,381 which is a loss - for EITC, self-employment losses can reduce earned income. Total earned income = $8,098 + (-$4,381) = $3,717 for a couple. However, self-employed pension contributions of -$1,095 (negative means this might be a repayment or the field represents a deduction). Taking earned income as approximately $3,717 for EITC. For married filing jointly, no children, 2026 federal EITC max is approximately $700 (phased in at 7.65% of earned income up to ~$9,160, phase out starts at ~$17,000 for joint). Federal EITC = min(0.0765 * $3,717, ~$700) = $284. NY EITC = 30% * $284 = $85. (2) NY Real Property Tax Credit - for household income under ~$18,000 with real estate taxes paid. Head's AGI-based income: taxable pension $10,031; spouse: wages $8,098, SE income -$4,381. Household income ~ $10,031 + $8,098 - $4,381 = $13,748. Real estate taxes = $1,550. The NY real property tax credit applies to renters/homeowners with household gross income under $18,000. Maximum credit is $375 for homeowners. The household income of ~$13,748 qualifies. The credit for homeowners is based on the excess of real estate taxes over 6% of household income: $1,550 - (0.06 * $13,748) = $1,550 - $825 = $725. The credit is limited to $375.

For a 1-person household in 2026, 130% FPL is approximately $1,632/month ($19,584/year) and 100% FPL is about $1,255/month. The household has essentially no listed income (only $1 in taxable interest). However, SNAP also applies asset/resource limits for households with an elderly (60+) member: $4,250 in countable resources. The household has $4,000 in bank account assets and $15,900 in vehicle value. SNAP generally excludes one vehicle (the most valuable) from resources in many states; California uses broad categorical eligibility (BCB) which eliminates the resource test for most households. Under California's broad-based categorical eligibility (BBCE), the resource limit is effectively waived. With near-zero income, the household would normally qualify. However, reviewing more carefully: the head is 70, a surviving spouse, with $1 in interest income. Monthly net income after deductions (standard deduction ~$204/month for 2026 for 1-person, shelter deduction for rent $600/month = $7,200/year): Gross monthly income \u2248 $0 (only $1/year). Net income after standard deduction = $0. Shelter costs: $600/month rent. Excess shelter = $600 - 0.5*$0 = $600, capped at shelter deduction limit (~$672/month for elderly). Net income = $0 - $204 (standard) - $600 (shelter) = negative, so $0. Maximum SNAP benefit for 1-person household in 2026 \u2248 $292/month = $3,504/year. Since net income is $0, benefit = max benefit = ~$3,504. But wait \u2014 I must check: there is no listed income at all except $1 interest. Under BBCE in California, all households receiving CalWORKs, SSI, or certain other benefits are categorically eligible, but this household has no listed benefits. Under standard SNAP rules with BBCE waiving resource limits, with essentially zero income, a 1-person elderly household would receive the maximum benefit. Annual SNAP \u2248 $3,504. However, I note the problem says 'treat any unlisted numeric input as 0' \u2014 no earned income, no Social Security, no other income listed. With $1/year gross income, the household qualifies and receives near-maximum benefit. For 2026, max allotment for 1-person is approximately $292/month (using 2025 value of $292 adjusted slightly).

Bank account is $4,000 which exceeds the $2,000 individual resource limit. However, the vehicle value of $15,900 - one vehicle is fully excluded for SSI regardless of value. So the only countable resource is the bank account at $4,000, which exceeds $2,000. This would normally disqualify the individual.

Without confirmed updated limits, applying standard $2,000 limit: ineligible. SSI = $0.

Ohio allows a deduction for health insurance premiums paid by the taxpayer ($2,500). Ohio adjusted gross income = $75,100 - $2,500 = $72,600. Ohio does not have a standard deduction per se but does have a personal exemption credit. Ohio taxes LTCG as ordinary income. Ohio taxable income = $72,600.

Reconsidering brackets more carefully: Ohio 2024: 0% on $0\u2013$26,050; 2.765% on $26,051\u2013$100,000.

For Medicaid eligibility under PolicyEngine rules, the key income-based test for adults (non-MAGI Medicaid for aged/blind/disabled in NY) considers income and assets. The household has a vehicle valued at $88,800 (well above typical asset limits), rental income (net loss of -$9,999), taxable interest of $1, and tax-exempt interest of $1. For aged/disabled Medicaid in NY (age 65+), there are asset limits (typically ~$16,800 for a single individual in 2026). The household vehicle value of $88,800 \u2014 while one vehicle may be exempt \u2014 combined with other household assets and the fact that the Head is a surviving spouse (which could affect asset counting), the vehicle value alone is very high. However, under standard Medicaid rules, one vehicle is typically fully exempt regardless of value. With no other listed countable assets and income consisting only of rental loss and minimal interest (~$2 total), the income is effectively near zero or negative, which would be well below the income thresholds. But PolicyEngine's NY Medicaid rules for aged individuals (65+) use a specific income and resource test. With only ~$2 in income and a net rental loss, income is minimal. The primary concern is countable resources, but since only the vehicle is listed (and one vehicle is exempt), there are no other listed countable assets. Under these rules, the Head would likely be income-eligible. However, aged/disabled Medicaid in NY (also known as Medicaid for the Elderly) has an income limit around 100% FPL (~$15,060 for 1 person in 2026). With essentially zero net income, the Head would be income-eligible. PolicyEngine may model NY Medicaid using MAGI-based rules or aged rules. Given the very low income and no non-exempt assets listed, the Head appears eligible. However, the surviving spouse status and the $88,800 vehicle \u2014 if PolicyEngine counts vehicle value as a resource \u2014 could disqualify.

The household vehicle value is $88,800. SSI allows one vehicle exempt from resources regardless of value (for transportation). However, the household has rental income listed as -$9,999 (a net loss), taxable interest of $1, and tax-exempt interest of $1. The key disqualifier here is the resource test: SSI has a $2,000 resource limit for an individual. The vehicle is worth $88,800. While one vehicle used for transportation is typically exempt, we must consider whether the full value applies. SSI exempts one vehicle entirely if used for transportation. With only one vehicle listed and assuming it is used for transportation, it would be exempt. However, the real estate (implied by $8,500 in real estate taxes) suggests property ownership beyond a home \u2014 but no home value is listed, so we cannot assume non-exempt property. Income-wise: the rental net loss of -$9,999 means no countable rental income; interest income totals $2/year, well below the SSI income exclusions ($20 general exclusion). The head is 79 and a surviving spouse, potentially aged/disabled eligible. But at the federal level in 2026, the SSI individual rate is approximately $967/month (~$11,604/year). With $2 in countable unearned income minus $20 general exclusion = $0 countable income, the full SSI benefit would apply. However, the $88,800 vehicle \u2014 if it cannot all be exempted \u2014 would exceed the $2,000 resource limit. SSI exempts only ONE vehicle for transportation use regardless of value. With only one vehicle in the household, it is fully exempt. No other non-exempt resources are listed. Therefore, the person appears SSI-eligible. Annual SSI federal benefit for an individual in 2026 \u2248 $967/month \u00d7 12 = $11,604. NY State supplements SSI; NY's supplement for a living-alone aged individual is approximately $87/month, bringing total to ~$1,054/month. But since no living arrangement is specified as 'alone' and household facts don't clearly indicate NY supplement eligibility category, using federal-only estimate of $11,604. Actually, re-examining: the rental loss of -$9,999 and real estate taxes of $8,500 suggest ownership of rental property. Rental property (beyond the home) is a countable resource at its equity value. If the person owns rental property with any positive equity, that would exceed the $2,000 resource limit and disqualify SSI. Since real estate taxes of $8,500 are listed and rental income (loss) exists, the person owns rental property. Its equity value is unknown but likely substantial, disqualifying SSI.

New York State refundable credits include the Earned Income Credit (requires federal EITC, which requires positive earned income \u2014 there is none here), the NY Child and Dependent Care Credit (no dependents or qualifying expenses listed), and the Real Property Tax Credit (requires qualified gross income under a threshold and renting or certain homeowners \u2014 rental income is negative suggesting property ownership, and real estate taxes of $8,500 are listed indicating homeownership, but NY's real property tax credit for homeowners requires that real property taxes exceed 6% of household gross income; however, gross income here is near $0 or slightly negative, so the credit could potentially apply). Reviewing NY's Real Property Tax Credit: it is available to homeowners with household gross income under $18,000. Gross income for NY purposes: taxable interest $1 + rental income (net loss of -$9,999, but NY uses gross rents for this credit calculation \u2014 however no gross rent is listed, only net rental income of -$9,999). With no positive earned income and minimal other income, no EITC-based credits apply. The real property tax credit for homeowners requires gross income under $18,000 and that real property taxes exceed 6% of income. Given income is essentially $0-$1, the credit would apply, but the household vehicle value of $88,800 \u2014 NY's real property tax credit excludes households with total net worth over certain limits, and the vehicle value alone suggests assets that may disqualify. Additionally, the credit amount for homeowners is limited based on income and taxes paid. However, NY's real property tax credit statute (Tax Law \u00a7606(e)) disqualifies claimants if they or their spouse owned and occupied the residence as a homeowner and had household gross income over $18,000 \u2014 income here is under $18,000. But the credit also requires that real property taxes exceed 6% of household gross income. With income near $0, this threshold is easily met. The maximum credit for a homeowner with income under $18,000 is capped \u2014 for a single person with income $0, the credit is based on a formula. However, NY's real property tax credit for homeowners provides up to $375 maximum. Given the complexity and that the vehicle asset value ($88,800) does not explicitly disqualify (NY's credit doesn't have an asset test based on vehicle value), but reviewing more carefully: the NY real property tax credit is primarily for renters and low-income homeowners. For homeowners, the credit = (real property taxes - 6% of gross income) \u00d7 applicable percentage. With gross income \u2248 $1 and taxes = $8,500, the excess = $8,500. The credit percentage for homeowners varies; for income under $18,000 the credit is limited to a maximum of $375. So the credit would be $375. However, the surviving spouse status and age 79 don't add additional refundable credits. Net result: approximately $375 from the NY Real Property Tax Credit. But given the rental loss situation and that no gross rental receipts are listed (only net = -$9,999), the household gross income for the credit is effectively $1 (interest). This makes the real property tax credit applicable at $375 maximum for homeowners."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No qualifying conditions (such as earned income or children) for NY state refundable credits were met."},"gemini-3.1-flash-lite-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"There are no refundable state credits applicable given the lack of income and specific low-income filing criteria."},"gemini-3.1-pro-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No qualifying income or dependents for state refundable credits."},"gpt-5.4-mini":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No refundable NY credits apply from the facts given."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No NY refundable credit eligibility indicators provided (e.g., eligible refundable credits); assume 0."},"gpt-5.5":{"prediction":375.0,"groundTruth":0.0,"error":375.0,"parsed":true,"score":0.0,"explanation":"Estimated NY refundable real property tax credit for an age-65-or-older homeowner with very low household income and $8,500 of real estate taxes, capped at $375."},"grok-4.1-fast":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No refundable NY state credits apply (e.g., no EITC equivalent for this profile)."},"grok-4.20":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No qualifying NY refundable credits like EITC given lack of earned income"},"grok-4.3":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No eligibility for New York refundable credits due to income and household composition."}},"tanf":{"claude-haiku-4.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"TANF is a needs-based program primarily for families with children.

Illinois allows a personal exemption of $2,425 for the filer (filing as married filing separately since 'separated' \u2014 in Illinois, separated individuals typically file as married filing separately or single; since they are separated but not divorced, they would file as married filing separately). For MFS, the personal exemption is $2,425. However, checking Illinois rules: the personal exemption for tax year 2026 is $2,425 per exemption. Head gets 1 exemption ($2,425). Children (3 dependents): each gets $2,425, so 3 \u00d7 $2,425 = $7,275. Total exemptions = $2,425 + $7,275 = $9,700. Net Illinois income = $97,400 - $9,700 = $87,700.

With one qualifying child and $600 in earned income, the EITC phase-in rate is 34%. EITC = $600 \u00d7 0.34 = $204. Since $204 is well below the maximum credit for one child (approximately $3,733 in 2026 after inflation adjustment from ~$3,618 in 2024), the credit is $204. The phase-out doesn't apply at this income level.\n\nChild Tax Credit (CTC): The child is age 1 (qualifying child). The CTC is $2,000 per child. The refundable portion (Additional CTC) is 15% of earned income above $2,500. Since earned income is only $600, which is below $2,500, the ACTC = 15% \u00d7 max($600 - $2,500, 0) = $0. However, checking if there's a minimum refundable amount \u2014 the ACTC floor for families with 3+ children doesn't apply here. So ACTC = $0.\n\nWait \u2014 re-checking: the non-refundable CTC reduces tax liability first. The head's tax liability on $600 wages (standard deduction of ~$15,000 for 2026) results in $0 tax. So the non-refundable CTC cannot be used. The ACTC = 15% \u00d7 ($600 - $2,500) = $0 since earned income is below $2,500 threshold.\n\nActually, for 2026, the TCJA provisions expire, reverting to pre-TCJA rules. Under pre-TCJA rules for 2026: CTC is $1,000 per child, and the refundable ACTC is 15% of earned income above $3,000. $600 < $3,000, so ACTC = $0.\n\nHowever, Congress may extend TCJA. Under current law for 2026 (TCJA expired), the standard deduction reverts to roughly $8,300 (single), CTC = $1,000. Tax on $600 wages with $8,300 standard deduction = $0. ACTC = 15% \u00d7 max($600 - $3,000, 0) = $0.\n\nSo total refundable credits = EITC $204 + ACTC $0 = $204.\n\nWait, let me reconsider EITC more carefully. For 2026 under pre-TCJA (current law): EITC parameters for one child: phase-in rate 34%, phase-in ends at ~$10,750, maximum credit ~$3,650 (2026 estimate). At $600 earned income: EITC = $600 \u00d7 0.34 = $204.\n\nActually, I need to reconsider whether TCJA extension legislation passes. Given the question says tax year 2026, I'll assume current law (TCJA expired). Under current law 2026: EITC with one child = $204. ACTC = $0 (earned income below $3,000 threshold).\n\nTotal federal refundable credits = $204 + $0 = $204.\n\nHmm, but I initially said $1,117. Let me reconsider if TCJA is extended (which is likely given the political environment in 2025-2026). If TCJA extended: CTC = $2,000, ACTC threshold = $2,500, ACTC = 15% \u00d7 max($600-$2,500,0) = $0. EITC same = $204.

Using 2025 values indexed: 2025 standard deduction for MFJ = $30,000 (already enacted under TCJA extension discussions; using $30,000 as a round figure for 2026). Additional standard deduction for age 65: ~$1,600 (indexed). Total standard deduction \u2248 $31,600. AGI = $34,400. Itemized deductions: real estate taxes $3,150 (capped at $10,000 SALT), medical expenses: total = $100 + $150 = $250, threshold = 7.5% \u00d7 $34,400 = $2,580, so $0 deductible. Total itemized = $3,150 \u2014 well below standard deduction of ~$31,600. Use standard deduction. Taxable income = $34,400 - $31,600 = $2,800. 2026 tax brackets for QSS (similar to MFJ): 10% on first ~$23,850 (indexed from 2025's $23,850). Tax = 10% \u00d7 $2,800 = $280. No credits apply (no children, no CDCC, no CTC). Federal income tax before refundable credits = $280. However, re-checking 2026 standard deduction: 2025 MFJ standard deduction = $30,000 per TCJA 2025 parameters. For 2026, applying ~2.6% inflation adjustment \u2248 $30,800. Additional for age 65 (one) \u2248 $1,600. Total \u2248 $32,400. Taxable income = $34,400 - $32,400 = $2,000. Tax = 10% \u00d7 $2,000 = $200. Given uncertainty in exact 2026 indexed amounts, the tax is in the range of $0-$280. Using conservative standard deduction of $30,000 + $1,600 = $31,600: taxable income = $2,800, tax = $280. No nonrefundable credits reduce this further.

To estimate SNAP eligibility: The household has no listed income, so gross income is $0. The net income test and benefit calculation would normally yield a benefit, but we must consider the asset/vehicle test. Florida uses categorical eligibility rules, but standard SNAP vehicle rules exempt one vehicle per household member for work; however, for households not categorically eligible, vehicles over a threshold count as a resource. Under standard SNAP rules, the vehicle value of $11,030 would be largely exempt (one vehicle is exempt up to its full value or a set amount). With no listed income, the net monthly income would be $0. The maximum SNAP benefit for a 1-person household in FY2026 is approximately $292/month ($3,504/year). However, the household has no listed income and no listed shelter expenses or utility costs, so the net income after deductions would be $0. The benefit would be 30% of net income subtracted from the maximum, but since net income is $0, the benefit would be the maximum. BUT: Florida has broad-based categorical eligibility (BBCE) through a TANF-funded program, which would eliminate the asset test. With $0 gross income and $0 net income, a 1-person household would receive the maximum benefit. However, the instructions say to treat unlisted expenses (rent, utilities) as 0. With no shelter costs and no income, the standard deduction for a 1-person household (~$198/month in 2026) would bring net income to negative, capped at $0. Maximum benefit for 1 person in FY2026 \u2248 $292/month. But wait \u2014 the household head is elderly/disabled. Elderly/disabled households only need to pass the NET income test (130% FPL net). With $0 net income, they qualify. Annual benefit \u2248 $292 \u00d7 12 = $3,504. However, since no income is listed and instructions say treat unlisted income as $0, and no shelter/utility expenses are listed (treat as $0), the excess shelter deduction is $0. Net income = $0 - $198 standard deduction = negative, floor at $0. Benefit = max benefit - 30% \u00d7 $0 = $3,504/year.

Medicaid eligibility in expansion states generally covers adults with income up to 138% of the Federal Poverty Level (FPL). However, in this household no income is listed \u2014 treating unlisted income as $0. At $0 income, the individual falls below 100% FPL. In expansion states, $0 income adults are typically still eligible for Medicaid (there is no income floor for expansion adults). However, PolicyEngine's PA Medicaid rules assess eligibility based on MAGI Medicaid criteria. With no income reported (treated as $0), the head's MAGI is $0, which is below 138% FPL (~$20,783 for a single adult in 2026). At $0 income in an expansion state, the individual would normally qualify. But PolicyEngine's rules also consider that individuals with no income who are not receiving certain other benefits may not be flagged as eligible through the standard ACA expansion pathway \u2014 and crucially, with $0 income (below 100% FPL), they would fall into a 'coverage gap' if the state had not expanded, but PA has expanded. With expansion, $0 income still qualifies.

The net income after deductions (standard deduction ~$204/mo, shelter deduction: rent $800/mo, shelter deduction capped at ~$672/mo for FY2026 for 1-person HH) results in net income near $0 or below. Maximum SNAP benefit for a 1-person household in FY2026 is approximately $292/month (adjusted for inflation from FY2025's $292). With $0 net income, benefit = 100% of max allotment. Annual benefit = $292 \u00d7 12 = $3,504. However, re-examining: FY2025 max for 1 person is $292/mo. For FY2026 (Oct 2025-Sep 2026), the COLA adjustment typically brings it to around $300-305/mo. Using $292/mo as a conservative estimate for 2026 tax year overlap: ~$292 \u00d7 12 = $3,504. But with zero income, the benefit equals the maximum allotment. For tax year 2026 (calendar year), using ~$217/mo as the estimated benefit after shelter and standard deductions on $0 income: standard deduction ($204), earned income deduction (0), shelter costs: rent $800/mo, excess shelter = $800 - 0.5\u00d7(0-$204) but net income before shelter = $0 - $204 = -$204, floor at 0, so excess shelter = $800 - 0.5\u00d7$0 = $800, capped at ~$672 for 1-person. Net income = $0 - $204 - $672 = negative, floor at $0. Benefit = 30% \u00d7 $0 subtracted from max = $292/mo. Annual = $292 \u00d7 12 = $3,504. Rounding to $3,504 but using $217/mo estimate seems too low. With zero net income, benefit = maximum allotment = $292/mo \u00d7 12 = $3,504.

The head is 65, which satisfies the age requirement. However, SSI has a resource limit of $2,000 for an individual. The household vehicle is valued at $21,680. SSI excludes one vehicle entirely if it is used for transportation, so the vehicle would not count as a resource. Bank account assets are $25, which is well under the $2,000 resource limit. For income, the head has $1 in taxable interest income. With virtually no countable income, the SSI benefit would be close to the 2026 federal benefit rate (FBR, approximately $967/month = ~$11,604/year). However, Texas does not supplement federal SSI, so only the federal benefit applies. The head has no earned or unearned income listed beyond $1 of interest, which reduces the FBR by $1 (unearned income exclusion of $20/month covers this). So the SSI benefit would be approximately $11,604/year. BUT \u2014 the over-the-counter health expenses ($8,000) and other medical expenses ($1,000) are not countable income or resources. There is no listed disability status for the head \u2014 only age 65 is noted. Age 65+ alone qualifies for SSI (aged category). With $1 interest income and $20 unearned income exclusion, countable unearned income = $0. No earned income. SSI = FBR \u00d7 12 \u2248 $967 \u00d7 12 = $11,604. However, given the instructions say to treat unlisted booleans as false and unlisted statuses as false, and no disability or blindness is listed \u2014 the head qualifies via age (65). But we must also consider: the real estate taxes of $7,500 suggest home ownership; a primary home is excluded from SSI resources. All factors considered, the head appears SSI-eligible with nearly full benefit. Using 2026 FBR estimate of ~$967/month: $967 \u00d7 12 = $11,604. However, since exact 2026 FBR is uncertain (2025 FBR is $967), I'll use $11,604 as the annual SSI amount. Wait \u2014 re-reading: 'Treat any unlisted numeric input as 0 and any other unlisted household fact, boolean, or status input as false.'

The Head's income consists of taxable interest ($8,160), taxable 401(k) distributions ($7,667), and tax-exempt interest ($3,840), totaling roughly $19,667 in gross income. For aged/blind/disabled Medicaid in Montana, the income limit is tied to the SSI/FPL thresholds. For a single individual in 2026, the income limit for aged Medicaid (e.g., QMB or standard aged Medicaid) is approximately $16,000\u2013$18,000/year in countable income; however, PolicyEngine's Medicaid eligibility rules for aged individuals often apply the ACA Medicaid expansion income threshold (138% FPL, ~$20,120 for a single person in 2026) or the aged/disabled pathway. Montana expanded Medicaid under the ACA. At 138% FPL for a single person (~$20,120), the Head's countable income (~$15,827 after deducting tax-exempt interest from MAGI or applying standard disregards) likely falls below the threshold. Under ACA MAGI rules, tax-exempt interest is added back, giving MAGI of ~$19,667, still below ~$20,120 (138% FPL). Additionally, as a 73-year-old, the Head qualifies under aged Medicaid pathways.

Federal AGI \u2248 $150,000 - $4,322 (trad 401k) + $28 (taxable interest) = $145,706 (IRA deductions likely phased out at this income level for those with employer plans). Michigan uses federal AGI as starting point. Michigan personal exemption for MFJ: $5,600 per filer \u00d7 2 = $11,200 (2026 estimate). Michigan does not allow itemized deductions; only specific subtractions. Michigan taxable income \u2248 $145,706 - $11,200 = $134,506. Tax at 4.05% \u2248 $134,506 \u00d7 0.0405 \u2248 $5,447. However, Michigan also allows a deduction for real estate taxes paid \u2014 Michigan does NOT allow real estate tax deduction on the state return generally. Michigan does have a homestead property tax credit, which is a refundable credit, not applicable here. Michigan nonrefundable credits are minimal (e.g., $600 exemption credit per exemption already counted above). Revised calculation: Michigan taxable income = Federal AGI minus Michigan personal exemptions. Federal AGI = $150,000 (wages) + $28 (taxable interest) - $4,322 (trad 401k) = $145,706. Michigan personal exemptions (2026): $5,600 each for head and spouse = $11,200 total. Michigan taxable income = $145,706 - $11,200 = $134,506. Michigan income tax = $134,506 \u00d7 0.0405 = $5,447. Michigan nonrefundable credits: Michigan has a $600 per exemption credit built into the exemption structure (already included). No other significant nonrefundable credits apply here. Revised to ~$3,745 after considering the Michigan tax rate may be 4.05% applied to a slightly lower base accounting for the exemption credit approach used by Michigan (Michigan uses a $600 nonrefundable credit per exemption rather than an exemption deduction in some years). If Michigan uses $600 credit per exemption: tax before credits = $145,706 \u00d7 0.0405 = $5,901; minus 2 \u00d7 $600 = $1,200 credits = $4,701. Using Michigan's standard approach for 2026 with the flat rate and personal exemption deduction method: $134,506 \u00d7 0.0405 \u2248 $5,447. Given uncertainty in exact 2026 rate (could be 4.05%), the best estimate is approximately $5,447 before refundable credits.

PA does not allow deductions for 401(k) contributions (traditional or Roth), IRA contributions, or most other deductions from federal AGI \u2014 PA taxes income on a gross basis with limited exclusions. However, PA does exempt retirement/pension income for taxpayers age 59.5+ from PA income tax. The head is age 73, which is above 59.5. PA Code Section 303(a)(3) exempts 'retirement income' for individuals who have reached age 59\u00bd or are permanently disabled. Wages/salaries are generally taxable compensation in PA regardless of age. At age 73 while still working, wages are taxable. Traditional 401(k) contributions: PA does NOT allow a deduction for 401(k) contributions \u2014 employee contributions to 401(k) plans are taxable in PA (PA taxes compensation before the 401(k) deferral for employee elective deferrals). So PA taxable compensation = $130,000 (full wages, as PA does not exclude 401(k) deferrals for employees \u2014 wait, actually PA does exclude employer-sponsored 401(k) elective deferrals from PA taxable compensation under Act 40 of 2005 for plans qualified under IRC 401(k)). Under PA law, after Act 40 of 2005, elective deferrals to employer 401(k) plans ARE excluded from PA taxable compensation. So PA taxable compensation = $130,000 - $4,631 (traditional 401k) - $817 (Roth 401k) = $124,552. Note: Roth 401(k) contributions are after-tax federally but PA also excludes them from compensation since they are elective deferrals under a 401(k) plan. Traditional IRA contributions are NOT deductible in PA. Interest income (taxable $2,720) is taxable in PA as interest/dividends class. Social Security benefits are NOT taxable in PA. Tax-exempt interest ($1,280) is not taxable. PA taxable income = $124,552 (compensation) + $2,720 (interest) = $127,272. PA tax = $127,272 \u00d7 3.07% = $3,907.25.

Adult 1's total income: private pension \u00a39,804 + dividend income \u00a31,098 = \u00a310,902. The personal allowance is \u00a312,570, so Adult 1's income (\u00a310,902) is below the personal allowance, meaning the remaining unused personal allowance is \u00a312,570 - \u00a310,902 = \u00a31,668. This unused personal allowance can be set against capital gains first: \u00a329,008 - \u00a31,668 = \u00a327,340 of gains remain taxable. Adult 1's taxable income is \u00a30 (income within personal allowance), so all gains sit in the basic rate band. The basic rate band for CGT in 2026-27 is \u00a337,700 (up to \u00a350,270 total income). Since \u00a327,340 fits entirely within the basic rate band, CGT is charged at 18% (residential property rate not indicated, so standard rate applies: 18% for basic rate). CGT = \u00a327,340 \u00d7 18% = \u00a34,921.20. Wait \u2014 let me reconsider the CGT rates for 2026-27. From October 2024, CGT rates changed to 18% (basic rate) and 24% (higher rate) for most assets (excluding residential property which stays at 18%/24%). For 2026-27, basic rate CGT = 18%, higher rate = 24%. Adult 1: income \u00a310,902 < personal allowance \u00a312,570, so unused PA = \u00a31,668 offset against gains. Taxable gains = \u00a329,008 - \u00a31,668 = \u00a327,340. All within basic rate band (basic rate band remaining = \u00a337,700). CGT = \u00a327,340 \u00d7 18% = \u00a34,921.20. Adult 2: no capital gains, CGT = \u00a30. Household total CGT = \u00a34,921.20. However, re-examining: the dividend income of \u00a31,098 \u2014 dividends are taxed separately but count as income for band purposes. Adult 1's income: pension \u00a39,804 + dividends \u00a31,098 = \u00a310,902, still below PA of \u00a312,570. Unused PA against gains = \u00a31,668.

As they are disabled and receiving Enhanced PIP daily living, they qualify for the LCWRA (Limited Capability for Work and Work-Related Activity) element of approximately \u00a3416.19/month (\u00a34,994.28/year). They also receive the housing cost element for private rent: the LHA rate in South West for a single person (shared accommodation rate age 44 - but since they have a disability/LCWRA they are exempt from the shared accommodation rate) - using a single room/1-bed LHA rate for South West, approximately \u00a3590.47/month is a reasonable estimate, but to be conservative I use a 1-bed LHA rate. Actually, for simplicity, rent is \u00a37,286/year (\u00a3607.17/month). The housing costs element is capped at LHA - for a single adult with LCWRA in South West, a typical 1-bed LHA rate is around \u00a3607-\u00a3650/month; I'll use the stated rent of \u00a3607.17/month (\u00a37,286/year) as it's likely within LHA limits. Income: miscellaneous income of \u00a39,746/year. UC work allowance: there is no earned income work allowance applicable here (no earnings), but there is no work allowance for housing costs element claimants with no earnings. The taper rate is 55% on income above the work allowance. Since there are no earnings, the work allowance doesn't apply - but miscellaneous/unearned income reduces UC pound for pound (100% taper on unearned income). Max UC = \u00a34,721.40 (standard) + \u00a34,994.28 (LCWRA) + \u00a37,286 (housing) = \u00a317,001.68/year. Deduction for unearned income: \u00a39,746 \u00d7 100% = \u00a39,746. UC = \u00a317,001.68 - \u00a39,746 = \u00a37,255.68. Wait - re-checking: for UC, unearned income reduces award pound for pound. Savings of \u00a3228 + corporate wealth \u00a3114 = \u00a3342 total capital, well below \u00a36,000 threshold so no tariff income. Max UC \u2248 \u00a317,001.68 - \u00a39,746 = \u00a37,255.68/year. However, re-examining the LCWRA amount for 2026-27 (uprated by ~1.7% from 2025-26 \u00a3416.19): approximately \u00a3423.35/month = \u00a35,080.20/year.

Deduct employee pension contributions of \u00a3620 and personal pension contributions of \u00a363 (gross relief at source, so basic rate tax relief is added, but personal pension contributions under relief at source are paid net, meaning the gross amount is \u00a363/0.8 = \u00a378.75, but for income tax purposes the basic rate relief is claimed at source, so the deduction from total income is \u00a378.75). However, under relief at source, the pension provider claims basic rate tax back from HMRC, so the individual's net income for tax is reduced by the gross personal pension contribution. Let me recalculate: Employee pension contributions (occupational, assumed salary sacrifice or net pay arrangement reducing taxable pay): \u00a3620. Personal pension contributions: \u00a363 net paid, gross = \u00a363 / 0.8 = \u00a378.75, this extends the basic rate band but doesn't reduce total income directly. Actually, for personal pensions under relief at source, the gross contribution extends the basic rate band rather than reducing net income. For employee pension under net pay arrangement, it reduces taxable pay. Assuming employee pension is net pay: taxable employment income = \u00a334,155 - \u00a3620 = \u00a333,535.

Standard allowance for a single claimant aged 25+: approximately \u00a34,998.84/year (\u00a3416.57/month \u00d7 12). Housing Cost Element: private renter in London, assumed LHA rate for inner London area for a single person (1-bed/shared accommodation LHA). The LHA for a single person under 35 would be shared accommodation rate, but Adult 1 is 47, so they get the 1-bedroom LHA rate. For inner London broad rental market area, 1-bed LHA in 2026-27 is approximately \u00a31,442.15/month (~\u00a317,305.80/year), but UC housing cost element is capped at actual rent of \u00a32,459/year (\u00a3204.92/month), which is lower than the LHA, so the housing element is \u00a32,459/year. Total UC before earnings taper: \u00a34,998.84 + \u00a32,459 = \u00a37,457.84. Earnings: \u00a3645/year.

Net earnings \u2248 \u00a3645 (below income tax and NI thresholds \u2014 NI primary threshold is ~\u00a312,570/year, so no NI; income tax personal allowance \u00a312,570 so no income tax).

However, re-checking work allowance: for UC, if the claimant has housing costs included in their award, the work allowance is \u00a3404/month (lower work allowance) = \u00a34,848/year, or \u00a30 if no housing costs. Actually, the lower work allowance (with housing element) is \u00a3404/month for 2026-27. Earnings \u00a3645 < work allowance \u00a34,848, so taper deduction = 0. UC = \u00a34,998.84 + \u00a32,459 = \u00a37,457.84. Wait \u2014 work allowance only applies if the claimant or partner is in work AND responsible for a child/young person OR has limited capability for work. Adult 1 has no children listed and no disability. Therefore no work allowance applies. Taper = 55% \u00d7 \u00a3645 = \u00a3354.75. UC = \u00a37,457.84 \u2212 \u00a3354.75 = \u00a37,103.09.

Total employee NI = \u00a33,016 + \u00a3512.60 = \u00a33,528.60. However, for 2026-27 the PT is expected to remain at \u00a312,570 and the main rate at 8% and additional rate at 2%. Let me recalculate carefully: PT = \u00a312,570, UEL = \u00a350,270. Between PT and UEL: (50,270 - 12,570) = 37,700 \u00d7 8% = 3,016. Above UEL: (75,900 - 50,270) = 25,630 \u00d7 2% = 512.60. Total = \u00a33,528.60. Adult 2 has \u00a30 wages so no NI. Household total employee NI \u2248 \u00a33,529. Note: re-checking 2026-27 thresholds \u2014 PT likely remains frozen at \u00a312,570, UEL at \u00a350,270. Final answer: \u00a33,528.60, rounded to \u00a33,529. Actually for 2026-27 the government confirmed NI thresholds remain frozen. Employee Class 1: 8% on \u00a312,570\u2013\u00a350,270, 2% above \u00a350,270.

For 2026-27, the first child rate is approximately \u00a326.05/week \u00d7 52 weeks = \u00a31,354.60. However, checking more carefully: 2024-25 first child rate = \u00a325.60/week; 2025-26 = \u00a326.05/week (uprated by ~1.7%).

Actually, to be precise with what is known: 2025-26 Child Benefit first child = \u00a326.05/week. For 2026-27 I'll use this rate as best estimate: 26.05 \u00d7 52 = 1,354.60. Child 1 is age 4, which is a qualifying child. There is one child, so only the first-child rate applies. Gross Child Benefit = \u00a326.05 \u00d7 52 = \u00a31,354.60. Note: HICBC not deducted here as instructed. Adult 1 earns \u00a343,263 which is above the \u00a360,000 threshold... wait, the HICBC threshold changed in 2024-25 to \u00a360,000 for full charge, but instructions say to report gross.

The work allowance for UC with no housing costs doesn't apply here since there is a housing element \u2014 wait, with a housing cost element, the work allowance is \u00a30 (no work allowance when housing costs are included for a claimant without children or limited capability for work). The taper is 55%. Earned income is \u00a333,396. Monthly earnings = \u00a333,396/12 = \u00a32,783. Monthly max UC (standard allowance ~\u00a3314.67/month under-25 + housing element). For a single person under 35 renting privately, they're entitled to the shared accommodation LHA rate in Wales. Using a rough shared accommodation LHA of about \u00a3300/month = \u00a33,600/year. Total max monthly UC = \u00a3314.67 + \u00a3300 = \u00a3614.67. With no work allowance (housing element present, no children/LCW), taper of 55% on all earnings: reduction = \u00a32,783 \u00d7 0.55 = \u00a31,530.65/month.

Total deductions: \u00a3976 + \u00a31,879 = \u00a32,855. Maximum UC: ~\u00a34,335. Award = \u00a34,335 - \u00a32,855 = ~\u00a31,480. However, savings above \u00a316,000 would disqualify entirely, but \u00a315,219 < \u00a316,000 so still eligible. Re-checking capital tariff: each \u00a3250 (or part thereof) above \u00a36,000 counts as \u00a34.35/month assumed tariff. \u00a39,219 / \u00a3250 = 36.876, so 36 complete units plus a partial unit = 37 units. Tariff = 37 * \u00a34.35/month * 12 = \u00a31,931/year. Award = \u00a34,335 - \u00a3976 - \u00a31,931 = \u00a31,428. Rounding and using 2026-27 UC standard allowance (single 25+) of approximately \u00a3311.68/month = \u00a33,740/year (uprated from 2024-25 \u00a3311.68 by ~1.7% each year): ~\u00a33,740 for 2025-26, ~\u00a33,804 for 2026-27. Recalculate: \u00a33,804 - \u00a3976 - \u00a31,931 = \u00a3897. Given uncertainty in exact uprating, estimated UC \u2248 \u00a3897/year.

Both are within the limit.\n  - First child/QYP element: ~\u00a3333.33/month\n  - Second child element: ~\u00a3287.92/month\n- Childcare element: \u00a30 (none stated)\n- Housing cost element (LHA for South East, 2-bedroom for single adult + 2 dependents): approximately \u00a3800\u2013\u00a31,000/month depending on area. However, I need to cap this at the LHA rate. A reasonable estimate for a 2-bedroom LHA in South East England for 2026-27 is approximately \u00a3900/month (~\u00a310,800/year). I'll use \u00a3900/month.\n- Disability/carer elements: \u00a30 (none stated)\n\nTotal maximum monthly UC: \u00a3316.98 + \u00a3333.33 + \u00a3287.92 + \u00a3900 = \u00a31,838.23/month\n\n2. TAPER/INCOME CALCULATION:\n- Annual wages: \u00a320,493 \u2192 monthly: \u00a31,707.75\n- Work allowance (has housing element, so lower work allowance): ~\u00a3404/month for 2026-27\n- Earnings above work allowance: \u00a31,707.75 - \u00a3404 = \u00a31,303.75\n- Taper at 55%: \u00a31,303.75 \u00d7 0.55 = \u00a3717.06/month reduction\n- Capital: savings \u00a38 (negligible); corporate financial wealth \u00a3168,339 \u2014 this is significant. UC uses a capital tariff: capital between \u00a36,000 and \u00a316,000 reduces UC by \u00a34.35/month per \u00a3250 over \u00a36,000. Capital above \u00a316,000 means no entitlement. Corporate financial wealth (shares/investments) counts as capital for UC purposes. \u00a3168,339 >> \u00a316,000 threshold, so the household is NOT entitled to Universal Credit.\n\nConclusion: Capital of \u00a3168,339 exceeds the \u00a316,000 UC capital limit, so Universal Credit = \u00a30."},"gemini-3-flash-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"The household is ineligible for Universal Credit because their capital (corporate financial wealth of \u00a3168,339) exceeds the \u00a316,000 threshold."},"gemini-3.1-flash-lite-preview":{"prediction":7378.07,"groundTruth":0.0,"error":7378.07,"parsed":true,"score":0.0,"explanation":"Calculated based on the standard allowance for a single claimant over 25 and child elements, minus earned income after work allowance and taper relief, plus housing cost contribution."},"gemini-3.1-pro-preview":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"The household's financial assets exceed the \u00a316,000 capital limit for Universal Credit, resulting in zero entitlement."},"gpt-5.4-mini":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No one in the household is stated to meet UC eligibility conditions such as low income, disability, or limited work capability; with the given earnings and rent alone, no UC is estimated."},"gpt-5.4-nano":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No low-income/earnings/tap-up details beyond moderate wage are provided; assume not eligible for UC, so amount = 0."},"gpt-5.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Although the household has low earnings and rent, reported financial/corporate wealth is above the \u00a316,000 Universal Credit capital limit, so the award is nil."},"grok-4.1-fast":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"No UC eligibility; private renters with significant assets (\u00a3168k corp wealth exceeds limits) and no stated disabilities/low income needs; wages above needs but assets disqualify."},"grok-4.20":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Capital (168339 corporate wealth + savings) far exceeds 16000 limit, so ineligible and UC=0"},"grok-4.3":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Capital of 168339 exceeds 16000 limit making household ineligible"}}},"scenario_057":{"capital_gains_tax":{"claude-haiku-4.5":{"prediction":0.0,"groundTruth":0.0,"error":0.0,"parsed":true,"score":100.0,"explanation":"Adult 1 has a capital loss of \u00a311,553.

However, under rules in force since May 2019, mixed-age couples where one partner is over State Pension age cannot claim Pension Credit and must instead claim UC. Assessing UC eligibility: the couple has no dependent children. The standard allowance for a couple (both over 25 based on Adult 2 age 34) is approximately \u00a3617.60/month = \u00a37,411.20/year. Adult 2 earns \u00a339,468 gross wages; with employee pension contributions of \u00a31,792 and personal pension contributions of \u00a3182, net earned income for UC = \u00a339,468 - \u00a31,792 - \u00a3182 = \u00a337,494.

However, income must first be calculated as net earnings after tax and NI for UC purposes. Adult 2 net earnings (after income tax and NI) on \u00a339,468 minus pension contributions of \u00a31,974 = taxable pay ~\u00a337,494.

Child age 8 (born ~2018) is post-April 2017, so ~\u00a3287.92/month uprated to ~\u00a3295.70/month. Revised monthly: \u00a3320.10 + \u00a3295.70 + \u00a3427.41 + \u00a3682.75 = \u00a31,725.96/month.

To determine the CGT rate, we need to assess Adult 2's taxable income. Adult 2 has: wages \u00a30, dividend income \u00a37,590, savings interest \u00a377. Total non-gain income = \u00a37,667. Personal allowance = \u00a312,570. Since \u00a37,667 < \u00a312,570, the remaining personal allowance = \u00a312,570 - \u00a37,667 = \u00a34,903. The chargeable gain of \u00a33,072 falls entirely within the remaining basic rate band (after personal allowance offset). However, capital gains on residential property attract 18%/24%, and other assets attract 18%/24% for basic rate taxpayers. But since we don't know the asset type (treating as unlisted), we use the standard rate. For 2026-27, CGT rates for non-residential property gains: 18% (basic rate) and 24% (higher rate). Adult 2's total income (\u00a37,667) plus gains (\u00a33,072) = \u00a310,739, still below the personal allowance of \u00a312,570. Since the gains fall within the unused personal allowance, the taxable gain after the annual exempt amount (\u00a33,072) plus income (\u00a37,667) = \u00a310,739 < \u00a312,570, meaning the gains are sheltered by the personal allowance remainder... Actually, the personal allowance applies to income, not gains. CGT is computed separately: chargeable gain \u00a33,072, taxable at the basic rate since total income \u00a37,667 is below the basic rate band threshold (\u00a350,270). The gain \u00a33,072 falls within the basic rate band (\u00a337,700 remaining after \u00a37,667 income uses some). Rate = 18%. CGT = \u00a33,072 \u00d7 18% = \u00a3552.96. However, re-examining: in the UK, the personal allowance is set against income first, not gains. Gains do not benefit from the personal allowance directly. So the CGT calculation is: chargeable gains = \u00a36,072, annual exempt amount = \u00a33,000, taxable gain = \u00a33,072. Rate: Adult 2's income \u00a37,667 is below basic rate threshold, so gains taxed at 18%. CGT = \u00a33,072 \u00d7 0.18 = \u00a3552.96 \u2248 \u00a3553.

Savings interest = \u00a377, which falls within the Personal Savings Allowance (PSA) for basic rate taxpayer = \u00a31,000, so \u00a377 is tax-free. Dividend income: Dividend Allowance = \u00a3500 (2026-27). Dividends above allowance up to basic rate band taxed at 8.75%. Total income = \u00a37,590 (dividends) + \u00a377 (savings) = \u00a37,667. Personal Allowance covers non-savings/savings first, but all income is within PA for non-dividend income. Actually, let me order correctly: savings interest \u00a377 is within PSA (\u00a31,000) \u2192 \u00a30 tax. Dividends \u00a37,590: first \u00a3500 is dividend allowance \u2192 tax-free. Remaining \u00a37,090 taxed at 8.75% (basic rate for dividends). However, we must check if Personal Allowance applies. PA = \u00a312,570. Total income = \u00a37,667, which is below PA of \u00a312,570. Wait \u2014 Personal Allowance reduces tax on all income including dividends. Since total income (\u00a37,667) < PA (\u00a312,570), no income tax is due... BUT the ordering rules matter: PA is set against non-savings income first, then savings, then dividends. With no non-savings income, PA = \u00a312,570 is set against savings (\u00a377), leaving \u00a312,493 of PA against dividends (\u00a37,590). All dividends are covered by remaining PA. So Adult 2 income tax = \u00a30.\n\nWait \u2014 but the Dividend Allowance is applied before PA in the ordering? Actually per HMRC rules, dividends are the top slice of income, and the Personal Allowance is allocated bottom-up. Since total income \u00a37,667 < PA \u00a312,570, all income is covered by the PA. Income Tax = \u00a30.\n\nHmm, let me reconsider. Actually the dividend allowance is a zero-rate band, not an exemption from the PA calculation.

However, Adult 1 receives PIP Enhanced Daily Living and Enhanced Mobility and is disabled for benefits, but disability status does not affect CGT directly. Adult 1's taxable gains are \u00a3795.

After the personal allowance of \u00a312,570, taxable income (excluding dividends for band purposes) would be assessed, but we need to determine the income tax band to apply CGT rates. Miscellaneous income \u00a315,939 + savings interest \u00a32,371 = \u00a318,310; after personal allowance \u00a312,570, non-dividend taxable income = \u00a35,740.

Total household CGT = \u00a3143.10, rounded to \u00a3143. Wait - re-checking: for 2026-27, CGT rates on non-residential property gains are 18% (basic rate) and 24% (higher rate). Adult 1's taxable income before gains: miscellaneous \u00a315,939 + savings interest \u00a32,371 = \u00a318,310. Less personal allowance \u00a312,570 = \u00a35,740 taxable income occupying basic rate band. Remaining basic rate band = \u00a337,700 - \u00a35,740 = \u00a331,960.

However, we need to check eligibility: Child Benefit is payable for children under 16, and for qualifying young people aged 16-19 who are in approved education or training. QYP1 is 19 and QYP2 is 16. For a 19-year-old, they must be in full-time non-advanced education or approved training; the problem states they are a 'qualifying young person' which implies they meet this criterion. For a 16-year-old, they similarly qualify. Since the household has no 'eldest child' listed before these two, we treat one as the eldest and one as additional. Using 2026-27 rates (uprated from 2025-26 rates of \u00a325.60/week eldest and \u00a316.95/week each additional by ~1.7% or using announced rates): For 2025-26, eldest is \u00a325.60/week and additional is \u00a316.95/week. For 2026-27, announced rates are \u00a326.05/week (eldest) and \u00a317.25/week (additional). Annual: \u00a326.05 \u00d7 52 = \u00a31,354.60 for eldest; \u00a317.25 \u00d7 52 = \u00a3897.00 for additional. Total = \u00a31,354.60 + \u00a3897.00 = \u00a32,251.60. Wait - let me reconsider. The 2026-27 rates: using April 2026 uprated rates. The 2025-26 rates are \u00a325.60 (eldest) and \u00a316.95 (each subsequent). For 2026-27 uprated by September 2025 CPI (approx 1.7%): eldest ~\u00a326.05, additional ~\u00a317.25. Total = (\u00a326.05 + \u00a317.25) \u00d7 52 = \u00a343.30 \u00d7 52 = \u00a32,251.60. However, re-reading: the question lists 'Qualifying young person 1' (age 19) and 'Qualifying young person 2' (age 16) - both are qualifying young people, not children. Child Benefit is also payable for qualifying young people. So both qualify. Annual total = \u00a326.05 \u00d7 52 + \u00a317.25 \u00d7 52 = \u00a31,354.60 + \u00a3897.00 = \u00a32,251.60.
