The subsidy cliff is the income threshold at which ACA Marketplace subsidies phase out completely. For 2026, that threshold is 400% of the Federal Poverty Level (FPL). A household earning even $1 above that line receives no Premium Tax Credit at all — their full unsubsidized premium becomes their responsibility overnight.
This matters enormously for families with variable or self-employment income. A small raise, a freelance project, or an investment gain can push income over the cliff and result in a large subsidy repayment when filing taxes.
The cliff returned in 2026 after temporary expanded subsidies (which had eliminated it from 2021–2025) expired December 31, 2025. Households that were previously subsidy-eligible above 400% FPL need to reassess their situation for 2026 coverage.
2026 subsidy cliff income thresholds (approximate):
If your income is near the cliff, income management strategies — like maximizing HSA or retirement contributions to reduce MAGI — may help you stay below the threshold. A broker can walk you through the options.
Yes. The subsidy cliff is a hard cutoff based on annual income — not a gradual phase-down. Earning $1 over 400% FPL means $0 in subsidies. This is why households near the threshold should track income carefully throughout the year and report changes to the Marketplace promptly.
Potentially yes. Contributions to a traditional IRA, 401(k), or Health Savings Account (HSA) reduce your Modified Adjusted Gross Income (MAGI), which is the income figure the IRS uses to calculate subsidy eligibility. If those contributions bring your MAGI below 400% FPL, you may qualify for a Premium Tax Credit. A tax advisor or broker can help you model this before year-end.
