The ACA subsidy cliff is back for 2026: above 400% of poverty, the premium tax credit drops to zero

The answer you’ll still hear

"There's no ACA subsidy cliff anymore — since 2021 your premium is capped at 8.5% of income, and even people earning above 400% of the poverty line still qualify for a subsidy."

As of 1 January 2026, with the American Rescue Plan / Inflation Reduction Act enhanced premium tax credits expired and no extension enacted by Congress, the ACA's 400%-of-poverty subsidy cliff is back for plan year 2026: IRS Rev. Proc. 2025-25 caps the applicable percentage at 9.96% and ends the table at 400% of the federal poverty line, so a household one dollar over that line gets a premium tax credit of zero.

What actually changed

The enhanced premium tax credits that most people now think of as "the ACA subsidy" were a temporary overlay. The American Rescue Plan Act (2021) and then the Inflation Reduction Act (2022) did two things: they set the top of the applicable-percentage table at 8.5% of income and, critically, they removed the old 400%-of-poverty eligibility ceiling — so for four years there was no cliff, and higher earners could still get help if the benchmark plan cost more than 8.5% of their income. That overlay was written to expire at the end of 2025, and Congress did not extend it. The House passed a three-year extension 230–196 on 8 January 2026, but it stalled in the Senate; competing Senate bills (the CARE Act and others) remained in negotiation and unenacted as of mid-2026.

So for 2026 coverage the statute reverts to its pre-2021 shape, and the IRS has already published the numbers. Revenue Procedure 2025-25 sets the 2026 applicable-percentage table for section 36B: the top bracket, "at least 300% but not more than 400%" of the federal poverty line, is 9.96%, and the table simply ends at 400%. There is no row above 400% — which is the cliff. Households at 401% of poverty are not charged a higher percentage; they get no premium tax credit at all.

The input most guides skip is which income the cliff is measured against. Eligibility turns on your household's modified adjusted gross income (MAGI) for the full 2026 tax year, reconciled on Form 8962 at filing — not the estimate you gave at enrollment. If a raise, a bonus, a capital gain, or a spouse's income pushes your year-end MAGI one dollar past 400% of the poverty line (based on the 2025 HHS poverty guidelines used for 2026 coverage), you don't just lose future subsidy — you can owe back every dollar of advance premium tax credit already paid to your insurer that year.

Who this hits

Middle-income marketplace enrollees sitting near the 400%-of-poverty line — roughly the low-to-mid five figures for a single person, higher for families. The pain concentrates on people who buy their own coverage and have variable or rising income: the self-employed, freelancers and gig workers, early retirees not yet on Medicare, and older enrollees (50–64), whose unsubsidized premiums are highest, so the dollar cost of falling off the cliff is largest. Anyone weighing a raise, a bonus, a Roth conversion, or extra contract work in 2026 while on a marketplace plan is exposed.

The current number, for you

A chat assistant will very likely tell you the cliff is gone — that answer was true from 2021 through 2025 and dominates its training data, so it repeats the 8.5% cap and "no 400% ceiling" as if they still hold. They don't for 2026. And even an assistant that knows the credits expired can't tell you your number, because it's branchy: it depends on your exact projected MAGI, your household size, your state's benchmark plan, and how close a raise pushes you to the 400% line — plus the repayment exposure if you cross it mid-year. Our ACA Subsidy Cliff Checker runs the 2026 pre-ARPA curve from Rev. Proc. 2025-25 against your household size, state, and income — it shows your poverty percentage, your estimated subsidy, exactly where the 400% cliff falls in dollars, and the new full-clawback repayment risk if your year-end income crosses it.
