- For tax year 2025 returns, a repayment cap still limits what you owe back on excess Advance Premium Tax Credit (APTC), topping out at $1,625 for a single filer between 300% and 400% of the federal poverty line (FPL).
- Starting with tax year 2026 returns, filed in 2027, that cap is gone at every income level. The Internal Revenue Service (IRS) confirms filers must repay the full difference, no matter how small their income.
- The 400% FPL eligibility ceiling also returns for 2026 coverage. Land one dollar over it and your allowable credit for the year drops to zero, with the full advance amount repayable.
- Marriage, divorce, and domestic-abuse allocation rules can still change what you personally owe, even after the general repayment cap disappears.

A single mother in Columbus, Ohio filed her 2025 tax return in March 2026 and found she owed the Internal Revenue Service (IRS) money back for health insurance help she had already spent. She had taken $2,400 more in Advance Premium Tax Credit (APTC), the subsidy the Health Insurance Marketplace pays directly to an insurer to lower a monthly premium, than her actual income allowed. A cap built into the tax code limited what she had to pay back to $1,625. Starting with tax year 2026 returns, filed in 2027, that same $775 of protection will not exist. The cap disappears completely, and the full difference gets added to whatever a filer owes.
What Advance Premium Tax Credit reconciliation is
When someone enrolls in a Marketplace health plan through HealthCare.gov or a state exchange, they estimate their household income for the coming year. Based on that estimate, the Marketplace calculates a Premium Tax Credit (PTC) and, if the filer chooses, pays some or all of it in advance directly to the insurance company each month as APTC. That lowers the premium bill right away.
At tax time, the filer reconciles the estimate against reality on IRS Form 8962. If actual income came in lower than estimated, the filer gets the difference back as part of their refund. If actual income came in higher, the filer owes back some or all of the excess APTC. This second scenario, called “excess advance payment of the Premium Tax Credit,” is what this article covers according to the IRS’s own Q&A on the Premium Tax Credit.
Every Marketplace enrollee who took APTC and whose actual income landed above their estimate needs to understand this mechanism, whether they are filing a 2025 return right now or planning 2026 coverage.
Who has to repay, and how the cap worked through tax year 2025
Anyone who received APTC and whose household income for the year, as a percentage of the federal poverty line (FPL) for their family size, came in higher than what they told the Marketplace, owes money back. The amount they owe, for tax year 2025 returns, is limited by an income-based repayment cap set out in Table 5 of the 2025 Instructions for Form 8962.
| Household income (% of FPL) | Repayment cap, filing status Single | Repayment cap, any other filing status |
|---|---|---|
| Less than 200% | $375 | $750 |
| At least 200% but less than 300% | $975 | $1,950 |
| At least 300% but less than 400% | $1,625 | $3,250 |
| 400% or more | No cap. Full excess APTC is repayable. | No cap. Full excess APTC is repayable. |
The cap works as a ceiling, not a discount. A single filer with $2,400 of excess APTC and household income at 350% of FPL for 2025 does not owe the full $2,400. They owe the smaller of the actual excess or their Table 5 cap, which at 350% of FPL and Single filing status is $1,625. That filer keeps $775 they would otherwise have had to repay.
If a household’s income for the year came in at 400% of FPL or higher, the cap already did not apply even under the tax year 2025 rules. Full repayment of every dollar of excess APTC has always been required at that income level. What changes below is which filers this “no cap” rule reaches.
What changes starting with tax year 2026 returns
The IRS states the change directly: “for tax years before 2026 (other than 2020), if your allowable credit is less than your advance credit payments, a repayment cap may limit the amount of the excess advance payment of the PTC that is subtracted from your refund or added to your balance due. However, for tax years after 2025 … there is no repayment cap and the total difference will be subtracted from your refund or added to your balance due,” per the same IRS Premium Tax Credit Q&A, updated February 19, 2026. (“PTC” is the same Premium Tax Credit defined earlier in this article.)
Using the same worked example: a single filer with $2,400 of excess APTC and 350% of FPL household income would have owed $1,625 on a tax year 2025 return. The identical facts on a tax year 2026 return, filed in 2027, produce a bill of the full $2,400. The gap between those two numbers, $775 in this example, is exactly what the cap used to protect and no longer does.
A second, related change lands at the same time. Congress temporarily removed the requirement that household income stay at or below 400% of FPL to qualify for any Premium Tax Credit at all, for tax years 2021 through 2025. That window has closed. Starting with 2026 coverage, the ordinary rule returns: household income must be at least 100% but no more than 400% of FPL for the filer’s family size to claim a credit. A filer who crosses 400% for 2026 does not just lose part of the credit. Their allowable credit for the year drops to zero, and every dollar of APTC paid on their behalf during the year becomes repayable in full, with no cap softening the number.
For context, the 2026 Federal Poverty Guidelines from the U.S. Department of Health and Human Services (HHS) put 400% of FPL at these annual household income levels for the 48 contiguous states and D.C.:
| Household size | 100% of FPL (2026) | 400% of FPL (2026) |
|---|---|---|
| 1 | $15,960 | $63,840 |
| 2 | $21,640 | $86,560 |
| 3 | $27,320 | $109,280 |
| 4 | $33,000 | $132,000 |
How to protect yourself before the change hits your return
Three things reduce exposure to a full, uncapped repayment.
First, report income changes to the Marketplace as soon as they happen, not at tax time. A raise, a new job, a bonus, or a spouse returning to work should trigger an updated estimate at HealthCare.gov or the state exchange, which keeps the eventual reconciliation gap smaller.
Second, know the allocation rules for marriage or divorce during the year. Couples married during 2025 may qualify for an Alternative Calculation for Year of Marriage under Worksheet 3 of the Form 8962 instructions, which can reduce repayment. Couples who divorced or separated allocate the policy amounts between separate returns, and each ex-spouse’s repayment cap is based on their own household income, not the couple’s combined income.
Third, know the domestic-abuse exception. A filer who is a victim of domestic abuse or spousal abandonment can file as married filing separately and still claim the credit, an exception to the rule that married-filing-separately filers normally cannot. That filer still repays their allocated share of excess APTC under whatever limitation applies for their tax year, but the exception protects their ability to claim the credit without involving an abusive spouse in a joint return.
Common reasons people get blindsided
This mistake catches people every filing season, and it will catch more of them starting with 2026 coverage. Do not assume the cap you remember from a prior return still applies. Filing a 2025 return now, including on extension, still gets Table 5’s protection. Budgeting for 2026 coverage does not: that protection is gone by the time you file in 2027, so a mid-year income jump carries its full weight with no ceiling.
Do not assume a small overage stays small, either. Under the old rule, even a large swing capped out at $1,625 or $3,250. Under the 2026 rule, a filer whose income comes in $10,000 over their estimate repays APTC tied to the whole $10,000 gap, not a capped fraction of it. And do not wait for a letter to check your number. The IRS reconciles on the return you file, not before, so update your Marketplace estimate now if your 2026 income already looks likely to run past it.
If your income instead looks like it could fall near the 100% of FPL floor, check whether your state’s Medicaid adult expansion covers you at a lower cost than a Marketplace plan; Medicaid adult expansion eligibility rules are separate from Marketplace subsidy rules. A sliding-fee health center prices care by income when neither option closes the gap.
Frequently asked questions
Do I still qualify for the repayment cap if I’m filing my 2025 return late, on extension? Yes. The repayment cap in Table 5 applies to tax year 2025 returns regardless of when you file them, including returns filed on extension by October 15, 2026. The cap disappears starting with tax year 2026 returns, which most filers submit in early 2027.
How does repayment get split if I got married or divorced during the year? Couples married during the year may qualify for an alternative calculation that can lower the repayment amount. Couples who divorced or separated allocate the policy’s premiums and APTC between their separate returns, and each ex-spouse’s repayment cap is based on their own household income, not the combined household income from before the split.
Does the domestic-abuse exception mean I don’t have to repay anything? No. It lets you file as married filing separately and still claim the Premium Tax Credit, which married-filing-separately filers normally cannot do. You still repay your allocated share of any excess APTC, subject to whatever repayment limitation applies for your tax year.
How do I know if my household income will cross 400% of the poverty line for 2026 coverage? Compare your projected 2026 household income against the federal poverty guideline for your family size, then check HealthCare.gov’s income calculator for the exact figure that applies to your coverage year, since the specific guideline year used follows its own Treasury rule rather than the calendar year of coverage.
What documents do I need to reconcile my Advance Premium Tax Credit? You need Form 1095-A, the Health Insurance Marketplace Statement, which the Marketplace sends by January 31 for the prior coverage year, plus Form 8962 itself, which you attach to your federal tax return to calculate and reconcile the credit.
