The premium tax credit is the subsidy that makes Marketplace coverage affordable, and it works differently from most tax credits. You can take it in advance, month by month, against your premium, based on an estimate of income you have not yet earned.
That advance structure creates the risk this guide is really about. If your income comes in higher than you estimated, the difference is settled on your tax return, and the rules for settling it changed after 2025.
This is general information, not advice for your situation. Confirm your own figures with the Marketplace and a tax professional.
Key takeaway
For 2026, eligibility runs from 100% to 400% of the federal poverty line. The temporary rule that removed the 400% cap applied only to tax years 2021 through 2025. And for tax years after 2025 there is no cap on repaying excess advance payments, so underestimating your income now creates unlimited exposure at filing time.

Who qualifies
The IRS conditions are cumulative. You qualify if you:
- Have household income within the eligible range
- Do not file as married filing separately, with limited exceptions for abuse or abandonment
- Cannot be claimed as a dependent by someone else
- Have Marketplace coverage with premiums paid by the return due date
- Cannot access affordable employer-sponsored coverage or a government programme such as Medicaid or Medicare
The income range is that household income is at least 100% but no more than 400% of the federal poverty line.
Confirm the dates before you planHealthCare.gov dates and deadlines ›Open Enrollment dates and the deadline for coverage starting 1 January. State-based Marketplaces can differ from these dates.The temporary expansion has ended
For tax years 2021 through 2025, Congress temporarily expanded eligibility by eliminating the requirement that household income may not exceed 400% of the federal poverty line. That was a time-limited change covering those years.
The practical consequence is a threshold effect. A household slightly above 400% of the federal poverty line and one slightly below can face very different net premiums, because the credit is not tapered away above the line.
If your income is near that boundary, the difference between an estimate slightly under and slightly over is not a small adjustment. It is worth modelling before you enrol.
The repayment change that matters most
Advance payments of the credit go straight to your insurer during the year. At filing, you reconcile them on Form 8962, comparing what was paid in advance against the credit you actually earned. Filing Form 8962 is mandatory if you received advance payments, even if you would not otherwise be required to file.
For tax years after 2025, if your allowable credit is less than your advance credit payments, there is no repayment cap. The full difference is subtracted from your refund or added to your balance due.
| Situation | What happens at filing |
|---|---|
| Income came in as estimated | Advance payments roughly match the credit; little to settle |
| Income came in lower | You may receive additional credit as a refund |
| Income came in higher | You repay the full excess, with no cap for tax years after 2025 |
| You received advance payments but did not file Form 8962 | The credit is not reconciled, which can affect future eligibility |
How to reduce the exposure
- Estimate income deliberately rather than optimistically, including bonuses, freelance work, capital gains and a partner's income.
- Report income changes to the Marketplace during the year, not at filing. Mid-year adjustments reduce the advance payment and shrink the settlement.
- Consider taking less than the full advance credit if your income is volatile, claiming the balance at filing instead.
- Watch the 400% boundary specifically if you are near it.
- Keep Form 1095-A when it arrives, since Form 8962 is completed from it.
Point two is the single most effective habit. The Marketplace can only act on information it has.
Confirm the dates before you planHealthCare.gov dates and deadlines ›Open Enrollment dates and the deadline for coverage starting 1 January. State-based Marketplaces can differ from these dates.Enrolment timing
HealthCare.gov lists Open Enrollment as starting 1 November, with 15 December the last day to enrol or change plans for coverage starting 1 January, and 15 January the end of Open Enrollment.
Outside that window, coverage generally requires a Special Enrollment Period following a qualifying life change. Medicaid and CHIP applications are accepted year-round. State-based Marketplaces can set different dates from the federal ones, so confirm yours.
A separate figure worth noting if you are weighing employer coverage: for plan years beginning in 2026, the affordability percentage used in that test is 9.96%.
Frequently asked questions
What is the income range for 2026?
At least 100% and no more than 400% of the federal poverty line. The temporary removal of the 400% cap applied to tax years 2021 through 2025.
What happens if I underestimate my income?
For tax years after 2025 you repay the full amount by which advance payments exceeded your credit. There is no repayment cap.
Do I have to file Form 8962?
Yes, if you received advance payments, even if you are not otherwise required to file a return.
Can I change my estimate during the year?
Yes, and you should. Reporting income changes to the Marketplace during the year adjusts the advance payment and reduces what has to be settled at filing.
When is Open Enrollment?
HealthCare.gov lists 1 November to 15 January, with 15 December as the deadline for coverage starting 1 January. State-based Marketplaces may differ.
Summary
Two things define the current position: the 400% federal poverty line ceiling applies again, and excess advance payments are repayable in full with no cap for tax years after 2025.
Estimate conservatively, report income changes as they happen, and check where you fall relative to the 400% boundary before you enrol.
