The 2026 ACA subsidy cliff, explained
For the 2026 plan year, one dollar of extra income can drop your premium tax credit from thousands of dollars to zero. Here’s why the cliff came back, the math behind it, and how to see where you stand.
What the “cliff” is
The ACA premium tax credit lowers what you pay for a marketplace health plan. Eligibility is measured as a percentage of the Federal Poverty Level (FPL) for your household size and state. For 2026, the credit slides from 100% up to 400% of FPL — and then it stops. At 400.00% of FPL a household still receives a credit; at 400.01% the credit is $0. That vertical drop, with no phase-out, is the “subsidy cliff.”
Why it’s back for 2026
From 2021 through 2025, a temporary “enhanced” premium tax credit removed the upper income limit and capped premiums at 8.5% of income — so there was effectively no cliff. That enhancement expired on January 1, 2026. For the 2026 plan year the credit reverts to its pre-2021 structure: a sliding subsidy from 100%–400% FPL, then a hard cutoff. The premium tax credit itself did not disappear — only the temporary enhancement lapsed — but the 400% cliff returns with it.
The math, briefly
The government sets an “expected contribution” — a percentage of your income you’re assumed to pay toward a benchmark plan (the second-lowest-cost silver plan for your household). Your credit is the benchmark premium minus that expected contribution. The percentage rises with income along the IRS applicable-percentage table and tops out at 9.96% from 300% to 400% of FPL. Past 400%, there is no percentage at all — the credit is simply zero. There is no 8.5% cap above the line anymore; that was part of the expired enhancement.
A worked example
Take a single 60-year-old in the contiguous states. For 2026, 400% of FPL for a household of one is about $62,600. Suppose the benchmark silver plan runs roughly $1,060 a month — about $12,720 a year. At an income just under the line (around 396% of FPL), the expected contribution is about 9.96% of income, so the credit is roughly $6,500 a year. Earn one dollar past $62,600 and that credit becomes $0 — the same plan now costs the full $12,720 out of pocket. That ~$6,500 swing is the cliff, and it grows with age and household size because the benchmark premium does.
Who it hits hardest
The drop is steepest for older, pre-Medicare households (roughly ages 55–64) who buy their own coverage. Unsubsidized premiums rise sharply with age, so the benchmark premium — and therefore the credit at stake — is largest exactly for the people sitting closest to the cliff. A modest raise, a Roth conversion, a capital gain, or one more contract job can tip a household of this age over the edge.
If you’re over the line
Being over 400% FPL does not lock you out of coverage. You can still buy any marketplace plan — you just pay full price with no premium tax credit. Households over 400% FPL also auto-qualify for a hardship exemption that allows buying a lower-cost Catastrophic plan. One caution for 2026: because the repayment caps were removed, taking too much advance credit and then earning more than you estimated means repaying the full difference at tax time.

Reflects current federal law as of June 1, 2026: the enhanced premium tax credits expired after 2025 and the 400% FPL subsidy cliff applies for the 2026 plan year. A bill to restore the enhancements passed the House in January 2026 but has not become law. The legislative status is live — verify current status on congress.gov.
