If you got financial help paying for a Covered California health plan and your actual income for the year came in higher than the estimate you gave at enrollment, yes — paying back Covered California credits is part of how the program works. The federal Advance Premium Tax Credit is settled up on your tax return, and any excess you received becomes money you owe the IRS. For households under 400% of the Federal Poverty Level, repayment is capped by income tier. Above 400% FPL, there is no cap, and you owe every dollar back.
Why You Might Owe Money Back
The subsidy is called an advance premium tax credit for a reason. When you enroll, you estimate what your household will earn for the coming year, and that estimate sets how much money flows straight to your insurance company each month to reduce your premium. The IRS doesn’t know your real income until you file. Once it does, it compares what you actually qualified for against what was paid on your behalf. Earn more than you estimated and you got too much help; the difference is a debt on your return. Earn less and you may get additional credit back as a refund.1Covered California. What Is Financial Help?
The credit itself is created by 26 U.S.C. § 36B, part of the Affordable Care Act.2Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan
How the Reconciliation Works at Tax Time
By January 31, Covered California sends you Form 1095-A. It lists your monthly premiums and the APTC paid to your insurer for each month of the prior year. You use those figures to complete IRS Form 8962, which does the actual math: it lines up the APTC you received against the credit your real income entitled you to. Whatever’s left over either reduces your refund, increases your balance due, or comes back to you as additional credit.3Internal Revenue Service. Instructions for Form 8962, Premium Tax Credit
Filing Form 8962 is not optional. If you received any APTC during the year, it has to be attached to your federal return.4Internal Revenue Service. Reconciling Your Advance Payments of the Premium Tax Credit
If your 1095-A has errors — wrong premium amounts, wrong months of coverage, wrong APTC figures — contact Covered California for a corrected form before you file. If a corrected 1095-A shows up after you’ve already filed, compare the two; if the changes move any of the numbers that flowed into Form 8962, you may need to amend your return with Form 1040-X.5Internal Revenue Service. Corrected, Incorrect or Voided Form 1095-A
How Much You Have to Repay Below 400% FPL
Federal regulations cap repayment for households whose income stays under 400% of the Federal Poverty Level. The caps for tax year 2025 (filed in 2026) run by income tier and filing status:6Internal Revenue Service. Instructions for Form 8962 (2025)
- Below 200% FPL: $375 for single filers, $750 for everyone else.
- 200% to below 300% FPL: $975 single, $1,950 otherwise.
- 300% to below 400% FPL: $1,625 single, $3,250 otherwise.
Those figures come from the tax year 2025 Form 8962 instructions and are adjusted periodically for inflation.7eCFR. 26 CFR 1.36B-4 – Reconciling the Premium Tax Credit With Advance Credit Payments
For context, the 2026 Federal Poverty Level for a single person is $15,960, which puts 200% FPL around $31,920, 300% around $47,880, and 400% around $63,840.8HealthCare.gov. Federal Poverty Level (FPL)
Above 400% FPL There Is No Cap
Cross 400% of the Federal Poverty Level and the caps disappear. You owe back every dollar of excess APTC, no matter how large.2Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan This is where a year-end bonus, a spouse picking up extra hours, or a one-time capital gain can turn into a serious tax bill. The line is a cliff, not a slope.
The cliff matters more starting in 2026. The enhanced premium tax credits from the Inflation Reduction Act, which had extended subsidy eligibility above 400% FPL and capped everyone’s premiums at 8.5% of income, expired at the end of 2025. As of early 2026, Congress was considering legislation to extend them, but the IRS published its 2026 applicable percentage table using the original ACA structure that ends subsidies at 400% FPL.9Internal Revenue Service. Revenue Procedure 2025-25 Under that structure, a single person earning $64,000 qualifies for zero subsidy, while someone earning $62,000 gets a premium capped at about 10% of income. If you’re anywhere near the line, tracking your income through the year is the single most useful thing you can do.
California’s State Subsidy Is Reconciled Separately
California runs its own Premium Assistance Subsidy for enrollees at or below 165% of the Federal Poverty Level, designed for 2026 to offset the expiration of the federal enhanced credits.10Covered California. 2026 California State Premium Subsidy Program If you received it, you reconcile it on your California return with the Franchise Tax Board, separately from the federal reconciliation. Repayment caps apply on the state side too, and any excess is paid back with your state return.
Cost-Sharing Reductions Are Never Repaid
If your income was below 250% FPL and you were in a Silver plan, you probably also got cost-sharing reductions that lowered your deductibles, copays, and out-of-pocket maximum. Those are not a tax credit and are never reconciled. You will not owe money back for cost-sharing reductions no matter what your income turns out to be. Both forms of help come through the same enrollment, but only the premium side gets settled up at tax time.
Life Changes That Cause a Surprise Bill
The most common trigger is an income increase you didn’t report — a raise, a new job, freelance work, a spouse going back to work. Household changes matter too. Marriage combines two incomes into one household and can sharply cut credit eligibility. A dependent aging off or getting their own coverage shrinks your household size, which lowers the poverty-level thresholds against which your income is measured and can push you into a higher percentage bracket.
Covered California asks you to update your account within 30 days of any change to income, household size, address, marital status, or access to other coverage.11Covered California. How to Update Your Account Reporting a change when it happens lets Covered California adjust your monthly APTC going forward instead of letting the overpayment stack up. Nine months of excess credit is a much bigger problem at tax time than one.
What Happens If You Skip Form 8962
Some people don’t file the form, either because they didn’t know they had to or because they were hoping to avoid owing. The IRS sends Letter 12C asking for the missing form, and any refund is held until you respond with a completed Form 8962 and your 1095-A.4Internal Revenue Service. Reconciling Your Advance Payments of the Premium Tax Credit
The bigger consequence is losing the subsidy itself. Fail to file and reconcile for two consecutive tax years and you become ineligible for APTC entirely; the Marketplace flags your account and denies advance premium assistance when you try to enroll for the following year. Even one missed year puts you at risk of losing your credit going forward.12Centers for Medicare & Medicaid Services. Failure to File and Reconcile (FTR) Operations FAQ Filing and paying back what you owe is always better than skipping the form and losing hundreds of dollars a month in future help.
If You Can’t Pay the Full Amount
An APTC repayment is treated like any other federal tax debt, so the IRS’s usual payment options apply. If you can clear the balance within 180 days, a short-term plan is free to set up online. For anything longer, an installment agreement lets you pay monthly; setup fees run from $22 to $178 depending on how you apply and how you pay, and low-income taxpayers can have the fee waived.13Internal Revenue Service. Payment Plans; Installment Agreements
Interest and penalties keep accruing until the balance is paid, so faster is cheaper. Having a payment plan in place generally keeps the IRS from filing a tax lien or moving to levy. Ignoring the bill is the worst option, because the debt doesn’t go away and the collection consequences get steeper with time.
