2026-coverage FPL tables built in
Uses the 2025 HHS poverty guidelines that govern 2026 Marketplace coverage - $15,650 + $5,500 per extra person in the lower 48 and DC, $19,550 + $6,880 in Alaska, $17,990 + $6,330 in Hawaii - so the 400% ceiling is right for the household size and state group.
Dollars to the cliff, not just a yes/no
Prints the exact 400% FPL ceiling and how many dollars the projected MAGI sits above or below it, so the preparer knows how much deductible contribution room closes the gap before 31 December 2026.
Repayment with the OBBBA caps removed
OBBBA section 71305 repealed the section 36B(f)(2)(B) repayment limits, which topped out at $1,625 for a single filer and $3,250 for everyone else, for tax years beginning after 31 December 2025 - so the tool repays every excess dollar, the way the 2026 return will.
Rev. Proc. 2025-25 applicable percentages
Applies the 2026 applicable percentage table - 2.10% below 133% FPL rising to a flat 9.96% from 300% to 400% FPL - interpolated inside each band, instead of the expired 0% to 8.5% enhanced-subsidy scale that chatbots still quote.
What a last deductible dollar buys
Re-runs the whole calculation with a planned HSA, IRA or SEP contribution subtracted from MAGI and shows the repayment after it, so the client can see what the contribution is worth before the filing deadline.

Questions people ask

What does this extension actually do?

It takes a client's projected 2026 MAGI, household size and state group and returns the 400% federal poverty line ceiling, the dollars above or below it, the applicable percentage from Rev. Proc. 2025-25, the allowed premium tax credit, and the advance credit that must be repaid on the 2026 return now that the repayment caps are gone.

Who is it for?

US tax preparers, enrolled agents, CPAs and ACA brokers who run year-end income projections for self-employed and early-retiree Marketplace clients. It is built for the conversation where a client asks how much a December bonus, Roth conversion or good sales month will cost them in repaid subsidy.

Why not just ask a chatbot or use a free 2025 calculator?

Most free calculators and chatbot answers still run the enhanced-subsidy rules that expired on 31 December 2025: a 0% to 8.5% contribution scale, no cliff above 400% FPL, and capped repayment. OBBBA section 71305 deleted the $3,250 cap, so for 2026 all three are wrong. This tool ships the Rev. Proc. 2025-25 table, the hard cliff and uncapped repayment.

What is free and what needs the key?

Every calculation is free and unlimited, in the popup and in the browser page, with no watermark and no run counter. The $60 key adds ownership and repetition: CSV export of your client runs for the workpaper file, and alarms before the 15 January enrollment close and the 15 April filing date.

What would this cost done by hand?

A CPA charges $200 to $400 an hour for tax services in 2026, and a cliff projection means pulling the HHS poverty table, the Rev. Proc. 2025-25 percentages and the Form 1095-A totals before you can answer. One such meeting costs more than the $60 key, and the arithmetic is the part that goes wrong.
