Do I have to pay back ACA subsidies?
Sometimes. Advance premium tax credits are reconciled on IRS Form 8962 with your actual income at tax time. If you earned more than you estimated, you repay some or all of the excess; if you earned less, you get the difference back. Starting with the 2026 tax year, the old repayment caps are gone, so an underestimate can mean repaying the full excess subsidy.

Whether you repay, and how much, depends on the tax year and on how far off your income estimate was. Through the 2025 tax year, households under 400% of the federal poverty level were protected by dollar caps on repayment. The 2025 federal tax law (Public Law 119-21, signed July 4, 2025) eliminated those caps for tax years beginning after December 31, 2025, so for 2026 coverage the full excess is repayable regardless of income. The rules below assume you took the subsidy in advance; if you pay full price all year and claim the credit at filing, there is nothing to pay back.
Repayment rules by tax year
| Tax year | If your actual income came in higher than estimated |
|---|---|
| 2025 and earlier | Repayment of excess advance credit was capped for households under 400% of the poverty level; caps ranged from $375 to $3,250 depending on income and filing status |
| 2026 and later | No caps. You repay the full excess advance premium tax credit on Form 8962, at any income level |
Two more 2026 changes raise the stakes. The enhanced subsidies expired at the end of 2025, so eligibility ends entirely above 400% of the poverty level. Cross that line by even one dollar of actual income and, for 2026, the entire year’s advance subsidy becomes repayable.
How reconciliation actually works
When you enroll, the marketplace pays your insurer an advance credit based on your projected household MAGI. The following spring, Form 8962 compares that projection to the MAGI on your tax return. You must file, and you must include Form 8962, in any year you received advance credits; skipping it can cost you subsidy eligibility in future years.
Worked example: a Jacksonville freelancer estimates $45,000 for 2026 and receives $600 per month in advance credit, $7,200 for the year. A new contract lifts her actual MAGI to $58,000. Suppose Form 8962 shows the credit she was actually entitled to was $4,900. The $2,300 difference is added to her 2026 tax bill. Under the old caps a portion might have been forgiven; for 2026 it is all repayable. Had her income instead dropped to $38,000, she would receive additional credit as a refund.
How to protect yourself
- Report income changes to the marketplace within the month they happen; the advance credit adjusts going forward and shrinks the year-end gap.
- Estimate conservatively if your income is lumpy. Taking a smaller advance and collecting the rest at filing is safer than the reverse.
- Watch the 400% line for 2026. Deductible IRA, HSA, or self-employed retirement contributions may lower MAGI, depending on your situation; a tax professional can tell you what applies to you.
Here’s the mistake I see people make: setting the income estimate once in November and never touching it. In 2026, that habit is what turns a good year of business into a painful April.
