When you apply for marketplace coverage, you estimate next year’s income. The government then pays part of your premium to your insurer each month based on that guess. At tax time, the IRS compares the guess to what you actually earned. If you guessed low, you give some of it back.
Everyone with a marketplace plan has lived some version of that. What changed is how much you can be asked to give back. Starting with 2026, premium tax credit repayment has no ceiling at any income. Here is what that means, who it affects, and what to do before you enter your 2027 estimate.
The Premium Tax Credit Repayment Cap Is Gone
The premium tax credit is the help you get paying your premium. When the government sends it to your insurer during the year, the IRS calls it the advance premium tax credit, or APTC. At tax time, you compare the two on IRS Form 8962. If your advance payments ran higher than the credit you actually qualified for, the difference is called excess APTC. That is what the IRS takes back in April.
Through tax year 2025, the law capped how much excess APTC most households repaid. If your income stayed under 400% of the federal poverty level (FPL), the most you owed ranged from $375 to $3,250. Starting with tax year 2026, that cap no longer exists. The IRS states it directly on its page about the end of the repayment caps: you now repay the full amount of any excess APTC.
The change comes from Section 71305 of Public Law 119-21. CMS cites that section in its guidance to marketplace agents and brokers, which our own licensing operates under.
| Household income (% of FPL) | 2025 tax year limit | 2026 tax year and after |
|---|---|---|
| Under 200% | $375 single / $750 all other filers | No cap: full repayment |
| 200% to under 300% | $975 single / $1,950 all other filers | No cap: full repayment |
| 300% to under 400% | $1,625 single / $3,250 all other filers | No cap: full repayment |
| 400% and above | No cap: full repayment | No cap: full repayment |
Look at the bottom row. People above 400% of FPL never had a cap, so nothing changed for them. What changed is that the protection everyone below that line relied on is gone. KFF lists the same 2025 limits, which apply to that tax year only.
This is a tax change, not an insurance change. Your plan, premium, and coverage work exactly as before. What changed is how one answer on your application plays out a year later. The main defenses are in your hands.
Two Clocks Are Already Running
This is not next year’s problem. There are two separate clocks, and the nearer one is already ticking.
Clock one: the coverage you have right now
If you have advance credits on a marketplace plan this year, you settle up under the new rule when you file next spring. As healthinsurance.org explains, the change applies to 2026 returns filed in early 2027.
So if your 2026 income is running ahead of last fall’s estimate, a bill may already be forming. It is not final yet. Updating your application now adjusts your credit for the remaining months, and you can start saving for April. If you are finishing a 2025 return on extension, the old caps still apply to it.
Clock two: the estimate you enter November 1
Open enrollment for 2027 coverage starts November 1, and you will enter a 2027 income estimate. For years, that number felt like a rough guess with a soft landing. This year, guessing low carries a cost it did not carry last year. Keep the two clocks separate. The first one is closer, and it covers money the government already paid your insurer.
Who is actually exposed
Most people will be fine. If you earn a steady salary and your income barely moves, your estimate is probably close. This change should not keep you up at night.
The real premium tax credit repayment risk sits with households whose income swings, or who live near the 400% line. Think of a contractor whose fourth quarter decides the year, or a realtor on commission. Think of a spouse who might go back to work, or an early retiree weighing a Roth conversion.
What This Looks Like in Real Life
Here is one illustration. The numbers are round and hypothetical. They show how the rule works, not what anyone will actually owe.
Meet Dana, a single self-employed contractor. Last fall she estimated a cautious $35,000 for 2026. Based on that guess, the Marketplace paid $650 a month toward her premium, or $7,800 for the year.
Then a strong fourth quarter pushed her actual 2026 income to $60,000. Say the credit she truly qualifies for works out to $4,400. Her excess APTC is $3,400.
Under the old rules, $60,000 put a single filer in the 300%-to-under-400% band. Dana’s repayment would have stopped at $1,625. Under the new rules, she repays all $3,400. Same plan, same income, same estimate. The bill is $1,775 larger. That gap is premium tax credit repayment without a cap.
Where this collides with the subsidy cliff
Now change one detail. Say Dana’s year ends at $66,000 instead.
In September, we explained why many Utah bills went up for 2027, including the return of the 400% FPL cliff when the enhanced credits expired. Crossing that line does not shrink your credit. It erases your eligibility for the entire year.
Combine the cliff with no cap, and you get the harshest premium tax credit repayment case in this post. At $66,000, Dana qualifies for no credit at all, so she repays all $7,800. Older enrollees have larger credits, so their number can run much higher. That is the consequence we did not yet have reason to cover in September.
Here is where the line sits. Eligibility for 2027 coverage uses the 2026 HHS poverty guidelines, which Utah shares with the other contiguous states.
| Household size | 100% of FPL | 400% of FPL (the cliff) |
|---|---|---|
| 1 | $15,960 | $63,840 |
| 2 | $21,640 | $86,560 |
| 3 | $27,320 | $109,280 |
| 4 | $33,000 | $132,000 |
| 5 | $38,680 | $154,720 |
Your current 2026 coverage uses the 2025 guidelines, so that line sits slightly lower. Income here means modified adjusted gross income, an ACA-specific figure, not gross receipts. If your year could land near the line, ask your CPA where you stand before December.
What You Can Do About It This Month
The marketplace still works. Your income estimate just deserves real attention now. The best defense against a surprise premium tax credit repayment is a handful of habits.
Estimate deliberately, not optimistically. Start from last year’s actual numbers, then adjust for what you know is coming. Aim for a realistic year, not your best case or a defensive low. Our marketplace health insurance team can walk through your estimate with you.
Report changes during the year. This is the single most effective safeguard, and almost nobody does it. When income moves, update your application using HealthCare.gov’s guide to reporting income and household changes. The Marketplace then adjusts your credit for the rest of the year. The IRS names prompt reporting as the way to avoid a balance due.
Consider taking less than the full advance credit. You can take all of it, part of it, or none of it in advance. Whatever you skip, you can still claim on your return. You trade some monthly cash flow for more certainty in April.
Watch the income you control. A Roth conversion, stock sale, year-end bonus, equipment sale, or retirement distribution can push income up. If you are near a threshold, talk with your CPA about timing first.
Set money aside, and keep your paperwork. If you are close to a line, a separate savings bucket turns an April surprise into an April inconvenience. And keep Form 1095-A when the Marketplace sends it in late January. Your tax preparer needs it to reconcile your credit.
Two overcorrections to avoid
Do not skip the advance credit entirely to dodge risk. For many households, paying full premium all year is a real strain, and usually an unnecessary one. The goal is accuracy and mid-year updates, not avoidance.
Do not panic and estimate high, either. A high estimate means you pay more every month and wait until April to get the difference back. There is no safe direction to be wrong in. There is only a more accurate guess.
Rethinking the marketplace altogether? Our guide to marketplace plans, private insurance, and health sharing compares the options honestly. Just know that coverage outside the marketplace comes with no premium tax credit at all.
The detail most coverage misses
If you are self-employed and take the self-employed health insurance deduction, there is a partial offset. Excess APTC you repay generally counts as premium you paid yourself. That can raise your deduction and recover part of the cost of a premium tax credit repayment.
The math is circular, since the deduction and the credit affect each other. The IRS covers it in Publication 974. It is a job for your CPA, but worth asking about by name.
Deadlines, and What Could Still Change
HealthCare.gov currently lists these dates for 2027 coverage:
- November 1: open enrollment starts.
- December 15: last day to enroll for coverage that starts January 1.
- January 15: open enrollment ends.
A federal court vacated the rule that would have shortened that window, and HHS has appealed. Confirm the dates before you count on them. Our guide to the 2027 marketplace plan changes covers the calendar too.
KFF reports that paid enrollment fell from 21.8 million to 19.2 million this year. We saw that trend forming in May, in ACA Enrollment Is Falling.
Congress could still act. As of today, the enhanced premium tax credits remain expired, and the 400% cliff applies to 2027 coverage. The House passed a three-year extension in January, but the Senate has not. The repayment cap is a separate provision, though. A deal restoring the enhanced credits would not automatically restore the caps. If either changes, we will update this post.
The Bottom Line
Starting with 2026, premium tax credit repayment means every dollar of excess, at every income. For steady earners, little changes. For variable-income households, a careful estimate and a mid-year update are now worth real money. Three things to do this month:
- Compare your 2026 income so far to last fall’s estimate, and report a change if it has moved.
- Set your 2027 estimate deliberately, and decide how much advance credit to take.
- If you are near a threshold, set money aside and loop in your CPA.
