Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

aptc

get_aptc_repayment_cap

Returns the cap on repaying excess advance premium tax credit (APTC) at tax time. For tax year 2025: Form 8962 Table 5 ($375/$750 below 200% FPL, $975/$1,950 at 200-300%, $1,625/$3,250 at 300-400%, single/other filing status; no cap at 400% or more). For tax year 2026 and later there is NO cap: the One Big Beautiful Bill Act (P.L. 119-21 sec. 71305) repealed it, so the full excess is repaid. Many models trained before 2026 still quote the old caps.

calculate

calculate_premium_tax_credit

Calculates the ACA Marketplace premium tax credit (IRC sec. 36B) the way Form 8962 does. For 2026 coverage the enhanced ARPA/IRA credits have expired (no extension enacted as of 2026-11-02): the IRS Rev. Proc. 2025-25 table applies (2.10% of income below 133% FPL rising to 9.96% at 300-400% FPL) and there is NO credit above 400% FPL. For 2025 the enhanced table applies (0% up to 150% FPL, 8.5% cap, no income limit). Returns FPL percentage, applicable figure, expected contribution, annual and monthly credit, and net premium. Models trained before 2026 often still apply the 8.5% cap to 2026.

federal

get_federal_poverty_level

Returns the federal poverty line (FPL) used for the ACA premium tax credit for a coverage year, household size and state, plus the 100%, 133%, 138%, 150%, 200%, 250%, 300% and 400% income thresholds. Coverage year Y uses the HHS guidelines published in year Y-1: 2026 coverage uses the 2025 guidelines ($15,650 for one person in the 48 states and DC, $19,550 Alaska, $17,990 Hawaii); 2025 coverage uses 2024; 2027 coverage uses 2026. Copied from the Federal Register notices, not model memory.

subsidy

check_subsidy_cliff

Shows the dollar effect of the 400% federal poverty line subsidy cliff that returned for 2026 coverage after the enhanced premium tax credits expired: the cliff income for the household, the credit at exactly 400% FPL, the credit at $1 more (zero), and the loss. With household_income it also gives the credit under 2026 rules, what the expired 2021-2025 enhanced rules would have given, and how much modified AGI must drop (for example through HSA or retirement contributions) to get back under the cliff.
