The 2026 ACA Subsidy Cliff: Will You Lose Your Savings?

What the 'subsidy cliff' is, and why it's back

The Affordable Care Act gives most people a premium tax credit — a subsidy that lowers what they pay for a Marketplace plan. From 2021 through 2025, a temporary law removed the hard income cap on that subsidy, so even higher earners got some help. That temporary boost expired at the end of 2025.

For 2026, the rules snap back to how they worked before: there's a hard cliff at 400% of the federal poverty level. Below that line, you may qualify for a subsidy. One dollar above it, and you can lose the entire subsidy — you pay full price for your plan. It's called a cliff because there's no gentle slope; you either qualify or you don't.

This is one of the biggest changes in the 2026 Marketplace, and a lot of people who got help in 2025 will be surprised to find they're over the line for 2026.

The income numbers that matter

The cliff is set at 400% of the federal poverty level, which depends on your household size. Using 2025 poverty figures as a guide, that works out to roughly $62,600 for a single person and about $128,600 for a family of four. These numbers update each year, so confirm the current figures on HealthCare.gov before making decisions.

The income that counts is your 'modified adjusted gross income' (MAGI) for the year — essentially your adjusted gross income plus a few add-backs. It's your expected income for the coverage year, not last year's.

Because the cliff is so sharp, being just over it is genuinely expensive. A household a few hundred dollars over 400% FPL can end up paying thousands more per year than one just under it. That makes managing your countable income unusually important for 2026.

How to stay under the cliff (legally)

Here's the good news: the income that counts is your MAGI, and there are legitimate ways to reduce it — which can keep you eligible for a subsidy worth far more than the contribution.

Contributing to a Health Savings Account (if you have an HSA-eligible plan) lowers your MAGI dollar-for-dollar. So does contributing to a traditional IRA or, if you're self-employed, a SEP-IRA or solo 401(k). For self-employed people, deductible business expenses also reduce countable income.

The timing of income matters too. If you can defer a bonus, delay selling an asset, or shift income between years, you may be able to keep a given year under 400% FPL. Because the cliff is so sharp, even a modest contribution that pulls you under the line can be worth thousands in preserved subsidy — the math often massively favors it.

What to do if you're near the line

If your income is anywhere close to 400% of poverty for your household size, 2026 is the year to plan carefully. Estimate your expected MAGI as accurately as you can, and see whether you're above or below the cliff.

If you're over, run the numbers on whether an HSA or retirement contribution could bring you under — and compare that cost against the subsidy you'd preserve. If you're well over and can't get under, you'll want to shop for the best full-price plan and consider higher-deductible options to keep premiums manageable.

This is exactly the kind of situation where a licensed agent earns their keep: they can estimate your subsidy at different income levels, show you the cliff for your household, and help you find the most affordable plan whether or not you qualify — all free.
