Form 1095-A can reduce your tax refund, and here is why: the form itself is informational, but it forces a reconciliation on your return that compares the advance premium subsidy your insurer received during the year against the Premium Tax Credit your final income actually qualifies you for. If the advance was larger than the credit you earned, the difference is added to your tax on Schedule 2, which comes straight out of your refund or gets added to what you owe.1Internal Revenue Service. Premium Tax Credit – Claiming the Credit and Reconciling Advance Credit Payments For 2026, that hit can be much larger than in recent years because Congress let the repayment caps expire and reinstated the 400-percent-of-poverty income cliff.
If you never received advance payments during the year, a 1095-A does not reduce your refund. It may increase it, because the reconciliation can go the other way and pay you a credit you didn’t take monthly. The refund damage only happens when advance payments exceeded your final credit.
How the Reconciliation Actually Moves Your Refund
Anyone who received the Advance Premium Tax Credit has to file Form 8962 with their return, even if they otherwise wouldn’t need to file at all.2Internal Revenue Service. Instructions for Form 8962 (2025) – Section: Who Must File Form 8962 does two things: it computes the credit you actually qualify for based on your final income and family size, and it subtracts the advance payments reported in Column C of your 1095-A.
Two outcomes are possible. If your final credit is larger than the advance payments, the difference is a refundable credit that either boosts your refund or offsets other tax.3Internal Revenue Service. Questions and Answers on the Premium Tax Credit If advance payments were larger, the overage is called excess APTC, and it lands on Schedule 2 as additional tax. Dollar for dollar, it reduces your refund.
Why the Numbers Don’t Match
The Marketplace calculates your advance subsidy from the income estimate you gave when you enrolled. It cannot see mid-year changes in real time, so the monthly payments keep going out at the enrollment level until you update the application or file your return.
Income coming in higher than estimated is the biggest single cause of a shortfall at tax time. A raise, a bonus, a spouse going back to work, a capital gain, or a traditional-to-Roth IRA conversion can all push your Modified Adjusted Gross Income above the projection. MAGI for this purpose starts with your AGI and adds back tax-exempt interest, nontaxable Social Security, and foreign earned income excluded on Form 2555.4Internal Revenue Service. Modified Adjusted Gross Income Municipal bond interest and the nontaxable portion of Social Security are the two most commonly overlooked when people estimate for the Marketplace.
Family size also matters. If a dependent you claimed on the Marketplace application later files their own return, your household shrinks and your credit can drop. It can also move in your favor: gaining a dependent mid-year raises the credit.
The Married Filing Separately Trap
Married couples generally have to file jointly to claim the Premium Tax Credit. File separately and you lose eligibility entirely, which turns every dollar of advance payments into excess APTC.5Internal Revenue Service. Eligibility for the Premium Tax Credit Narrow exceptions exist for victims of domestic abuse or spousal abandonment, and for spouses who lived apart for the last six months of the year and meet other conditions. The Form 8962 instructions carry the specifics.
The Employer Coverage Trap
Getting advance payments doesn’t mean you were eligible for the credit. For each month, you must not have had access to other qualifying coverage, including affordable employer-sponsored insurance that meets minimum value, Medicare, Medicaid, or TRICARE.5Internal Revenue Service. Eligibility for the Premium Tax Credit For 2026, employer coverage counts as affordable if your share of the self-only premium is at or below 9.96 percent of household income.6Internal Revenue Service. Updates to Questions and Answers About the Premium Tax Credit Someone who declines an affordable employer plan, enrolls in the Marketplace with advance payments, and then finds out at filing time that the credit didn’t apply is looking at full repayment.
Why 2026 Hits Harder Than Prior Years
Two changes make excess APTC a bigger threat to your refund starting with the 2026 tax year.
First, the repayment caps are gone. From 2021 through 2025, lower-income households had their repayment limited to a set dollar figure based on income and filing status, sometimes only a few hundred dollars regardless of how large the overpayment was. That protection expired.6Internal Revenue Service. Updates to Questions and Answers About the Premium Tax Credit Now every dollar of excess is owed back. A household that used to owe $350 on a $3,000 overpayment now owes the full $3,000.
Second, the 400 percent of federal poverty level cutoff is back. Between 2021 and 2025, households above 400 percent FPL could still receive some credit on a sliding scale. For 2026, the cliff is hard again: at or above 400 percent FPL, the credit is zero. The threshold is $63,840 for a single filer and $132,000 for a family of four.7U.S. Department of Health and Human Services. 2026 Poverty Guidelines – 48 Contiguous States A household that estimated income below the cliff and ends up above it, even by a dollar, owes back every cent of advance payments received during the year.
The One Situation Where You Usually Don’t Repay
If you estimated income at or above 100 percent of the federal poverty level when you enrolled and your actual income comes in below that floor, the IRS generally won’t require repayment of the advance payments, provided you didn’t intentionally or recklessly inflate your income to get the subsidy.8Centers for Medicare & Medicaid Services. Are Consumers Required to Pay Back All of Their APTC if Their Household Income Ends Up Below 100% FPL This protection survived the elimination of repayment caps. Honest job loss and miscalculation are treated differently from a knowing overstatement, which can lead to denial of the credit and full repayment.
Check Your 1095-A Before You File
The Marketplace sends Form 1095-A by mail no later than mid-February, and it is generally available in your Marketplace online account between mid-January and February 1.9HealthCare.gov. How to Use Form 1095-A, Health Insurance Marketplace Statement If it doesn’t show up in your account under “Tax Forms,” call the Marketplace at 800-318-2596.10Internal Revenue Service. Corrected, Incorrect or Voided Form 1095-A Don’t file without it.
Look at Column A (enrollment premium), Column B (second lowest cost Silver benchmark), and Column C (advance payment) for each month. If any of those numbers look wrong, you cannot correct the form yourself. Contact the Marketplace, which will investigate and issue a corrected 1095-A and report the update to the IRS.11Centers for Medicare & Medicaid Services. How Can I Help My Clients Make Corrections to Their Form 1095-A Wait for the corrected form before filing. If you already filed on the wrong numbers, you’ll need to amend using Form 1040-X with a revised Form 8962.
Purely demographic errors, like a misspelled name or wrong Social Security number, don’t need a corrected 1095-A. Fix those directly on your return.
What Happens If You Skip Form 8962
You cannot avoid the reduction by leaving Form 8962 off your return. The IRS either rejects the return or holds your refund and sends a notice asking for the missing form. Your refund is not released until the reconciliation is done.3Internal Revenue Service. Questions and Answers on the Premium Tax Credit
The longer-term consequence is worse. Failing to file and reconcile causes the Marketplace to cut off your advance premium assistance for future years. You’d stay enrolled, but you’d owe the full unsubsidized premium every month until you go back and file.12Centers for Medicare & Medicaid Services. What Does Failure to File and Reconcile Mean You could still claim the credit as a lump sum when you file for that later year, but the lost monthly premium reduction makes coverage unaffordable for a lot of households in the meantime.
With repayment caps gone in 2026, skipping the form is a bigger trap than before. The excess APTC is owed either way, and dragging the reconciliation out only adds the loss of future subsidies to the bill.
