Will I have to pay back my ACA subsidy in full when I file my 2026 taxes?

Yes — if you received more advance premium tax credit in 2026 than you qualify for, you now have to repay all of the excess. Starting with the 2026 tax year (the return you file in early 2027), the One Big Beautiful Bill Act removed the repayment caps that used to limit how much lower- and middle-income households owed back. Before, if your final income stayed under 400% of the federal poverty level, the IRS capped your repayment at a set dollar amount based on income and filing status; only people above 400% repaid everything. Now everyone repays the full difference on IRS Form 8962, no matter their income. The most common trigger is earning more than you estimated — a raise, a new job, side income, a bonus, or a retirement-account withdrawal. Because 2026 subsidies are figured using the 2025 poverty guidelines, a single person whose 2026 income lands above $62,600 (400% FPL) qualifies for no credit at all and must repay every advance dollar paid to their insurer.

What it means

This is the first tax season under the new rule. Many people will not notice until they file in February to April 2027.
The repayment is added to your tax bill or subtracted from your refund — it is not billed by your insurer.
Example: a single enrollee estimated $30,000 of income and got about $350 a month in advance credit. Their actual 2026 income came in at $45,000, which shrinks the credit they qualify for. Under the old rules part of that excess was capped; under the new rules every dollar of the difference is due.
Going the other way still works: if your income came in lower than estimated, you may get extra credit back as a refund.
The 2027 plan year works the same way, so the estimate you enter during this open enrollment matters more than it used to.

Action steps

Pull your 2026 pay stubs and other income now and compare against what you told the Marketplace.
If your 2026 income ran high, set money aside before you file so the repayment is not a surprise.
When you apply for 2027 coverage, use a realistic — not optimistic — income estimate.
Report income changes to the Marketplace as soon as they happen so your advance credit adjusts during the year.
Consider taking less than the full advance credit if your income is unpredictable; you can claim the rest at tax time.
Ask a tax professional about how your situation is taxed, and a licensed agent about adjusting your 2027 subsidy.

Risks & deadlines

Tax year 2026 return (filed in 2027): first year with no repayment cap.
Income above 400% of the poverty level for the year means no premium tax credit for that year — all advance payments are repaid.
Not filing Form 8962 to reconcile can cost you your subsidy in future years.
