This is the most consequential change to marketplace coverage that most people have not heard about, and it lands for the first time on the return you file in early 2027. The caps that limited how much excess subsidy you had to pay back have been repealed. If you take advance premium tax credits and your income comes in higher than you projected, you now repay all of it.
Advance premium tax credits are paid to your insurer monthly, based on the income you project for the coverage year. At tax time, IRS Form 8962 reconciles what you received against what you actually qualified for.
Until now, if that reconciliation went against you, the amount you had to repay was capped by statute. The caps scaled with income, and anything above the cap was simply forgiven. For a lot of households that turned a potentially serious bill into a manageable one.
The One Big Beautiful Bill Act repealed those caps for tax years beginning after 2025. From tax year 2026 there is no cap at any income level. The excess is owed in full.
Who this actually hits
Not everyone. If you are salaried, your income is predictable and your estimate is close to a lookup. Reconciliation for you is usually a rounding error in either direction.
The exposure concentrates on people whose income is a forecast rather than a fact:
- Self-employed and 1099 workers — where a strong Q4 can move the whole year
- Anyone on commission or bonus — the variable part is the part that breaks the estimate
- Seasonal and contract workers, including travel nurses whose assignments do not evenly fill a year
- Owner-operators and small business owners whose draw depends on how the year goes
- Anyone with capital gains — selling an asset can quietly push a household over a threshold it was nowhere near in January
The 400% cliff makes it worse
There is a second edge that interacts badly with the repeal. Premium tax credit eligibility ends above 400% of the federal poverty level. That is not a taper — it is a cliff.
Cross it, and you were not entitled to any premium tax credit for the year. Combine that with the removal of repayment caps and the arithmetic is unforgiving: a household that took advance credits all year and finished slightly above the line now repays the entire year of assistance, uncapped.
The enhanced subsidies that temporarily softened this expired at the end of 2025, so the cliff is back at full height at the same moment the caps came off.
What to do differently
| Instead of | Do this |
|---|---|
| Estimating the middle of your range | Estimate toward the top of your realistic range. Overestimating gets refunded; underestimating no longer has a ceiling. |
| Setting it in November and forgetting it | Update the marketplace when income changes. Reconciliation runs month by month, so a September correction protects the rest of the year. |
| Counting only your main income | Count everything in MAGI — contract work, a spouse’s earnings, interest, capital gains, retirement distributions. |
| Taking the full advance credit automatically | Consider taking less than you qualify for. You can claim the remainder at filing instead, which converts repayment risk into a refund. |
That last row is the option people most often do not know exists. Advance credits are not all-or-nothing: you can elect to take a portion monthly and reconcile the rest at tax time. For someone with genuinely unpredictable income, deliberately under-claiming is a way to buy certainty.
Modified adjusted gross income is not fixed until the return is filed, and several things legitimately reduce it: health savings account contributions, traditional IRA contributions, self-employed retirement plans such as a SEP-IRA or solo 401(k), and ordinary business deductions.
Deadlines differ by vehicle, and some run past December 31. If you suspect you have gone over, that conversation with a tax professional is worth having in the autumn rather than in April, when most of the options have closed.
This is not a reason to skip coverage
It is worth being clear about what this change does and does not mean. Marketplace subsidies are still substantial, still available, and still the main route to affordable coverage for most people who do not get it through an employer. Nothing here argues for going uninsured, and going uninsured to avoid a reconciliation risk would be a considerably more expensive mistake.
What it argues for is treating the income question on the application as a real decision rather than a formality. It is the single field that determines everything downstream, and the cost of getting it wrong in one direction just stopped being bounded.
If your income is variable, the freelancers and gig workers guide goes further into how to build the estimate. Deadlines for enrolling or making changes are on the 2027 deadlines by state page.
