Health insurance bought through the Marketplace shows up on your taxes in one specific way: if you received a premium tax credit to lower your monthly premiums, you have to reconcile that credit against your actual income when you file. The Marketplace sends you Form 1095-A, you attach Form 8962 to your 1040, and the math either produces a refund, reduces your tax, or creates a balance you owe back. For the 2026 tax year, that reconciliation carries more risk than it has in years, because the temporary rules that softened repayments expired.
The Two Forms You’ll Need
If you had Marketplace coverage at any point during the year, two forms drive the tax side.
Form 1095-A arrives from the Marketplace by mid-February. It lists your monthly premiums, the advance credits paid on your behalf, and the cost of the benchmark silver plan in your area.1HealthCare.gov. How to Use Form 1095-A, Health Insurance Marketplace Statement Do not file your return until you have it. Without those numbers, Form 8962 can’t be completed accurately, and filing without reconciling creates problems that follow you into the next enrollment year.
If anything on the 1095-A looks wrong, incorrect premiums, missing months, wrong household members, contact the Marketplace for a corrected version. The Federally-facilitated Marketplace call center is 800-318-2596; state-based Marketplaces have their own numbers. If you already filed using bad data and later receive a corrected form, you don’t have to amend unless the correction lowers your tax, though you may amend either way.2Internal Revenue Service. Corrected, Incorrect or Voided Form 1095-A
Form 8962 is where the reconciliation actually happens. You transfer figures from the 1095-A, calculate your final premium tax credit based on your actual household income, and compare that to the advance payments made on your behalf during the year.3Internal Revenue Service. The Premium Tax Credit – The Basics The form attaches to your 1040. If any advance credit was paid on your behalf during the year, filing 8962 isn’t optional.
How Reconciliation Turns Into a Refund or a Bill
Advance credits are calculated from the income you estimated when you enrolled. By year’s end those estimates rarely match reality, and the difference has to be settled on your return.
If your actual income came in lower than your estimate, your credit is larger than what was paid in advance. The difference lands as a refund or reduces your tax bill. If your income came in higher, you received more advance credit than you actually qualified for, and you owe the excess back.4Internal Revenue Service. Questions and Answers on the Premium Tax Credit
The worst outcome is crossing the 400% federal poverty level threshold. If your final household income lands above 400% FPL, you lose the credit entirely and must repay every cent of advance payments made during the year.5Internal Revenue Service. Eligibility for the Premium Tax Credit For a single filer in 2026, that cliff sits at $63,840. A late-year bonus, freelance income, or a capital gain can push you across it without warning.
What Changed for the 2026 Tax Year
Two shifts hit at the start of 2026, and both raise the cost of getting your income estimate wrong.
First, the income ceiling is back. From 2021 through 2025, Congress temporarily removed the 400% FPL cap so that anyone whose benchmark premium exceeded 8.5% of household income could still receive some credit. That expansion expired on January 1, 2026, and the original ACA rule is again in force.6Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan Income above 400% FPL now means zero credit and full repayment of any advance amounts received.5Internal Revenue Service. Eligibility for the Premium Tax Credit
Second, repayment caps are gone. Before 2026, lower-income taxpayers who received excess advance credits had a safety net capping repayment at a few hundred to a few thousand dollars depending on income and filing status. Public Law 119-21, enacted in July 2025, eliminated all repayment caps starting with tax year 2026.7Congress.gov. Public Law 119-21 If your advance payments exceeded your final credit by $3,000, you owe $3,000. No exceptions based on income level.8Internal Revenue Service. IRS Updates Frequently Asked Questions on the Premium Tax Credit
Expected contribution percentages also rose sharply. A household at 200% FPL that owed 2% of income toward the benchmark in 2025 owes 6.6% in 2026. Every bracket above 150% FPL faces a higher expected contribution than it did during the expansion years.9Internal Revenue Service. Rev. Proc. 2025-25 Smaller subsidies mean smaller reconciliation cushions.
Who Still Qualifies
For 2026, household income must fall between 100% and 400% of the federal poverty level.5Internal Revenue Service. Eligibility for the Premium Tax Credit In dollar terms:
- Single individual: $15,960 to $63,840
- Family of two: $21,640 to $86,560
- Family of four: $33,000 to $132,000
Alaska and Hawaii use higher thresholds.10HealthCare.gov. Federal Poverty Level (FPL)
Beyond income, you must live in the U.S., be a citizen or lawfully present, and not be incarcerated.11HealthCare.gov. Are You Eligible to Use the Marketplace You must file a federal return, and married couples generally must file jointly. Victims of domestic abuse or spousal abandonment may file separately and still claim the credit.5Internal Revenue Service. Eligibility for the Premium Tax Credit
Other coverage can disqualify you. If your employer offers a plan where your share of the premium doesn’t exceed 9.96% of household income and the plan meets minimum value standards, you can’t claim a Marketplace credit even if the Marketplace plan would be cheaper.12U.S. Department of Labor. Health Insurance Marketplace Coverage Options and Your Health Coverage Medicare and Medicaid eligibility also end the credit.
Update the Marketplace When Your Life Changes
Because reconciliation now carries no cushion, keeping the Marketplace informed during the year matters more than it used to.
Income changes are the biggest one. A new job, a raise, lost hours, a spouse starting or stopping work, all of these can shift you into a different subsidy range. Reporting the change lets the Marketplace adjust your advance payments so you’re not staring at a large repayment in April.
Family size matters too. Adding a dependent through birth or adoption raises your household size and can lift your income threshold. Divorce works the other direction for the higher-earning spouse. Becoming eligible for Medicare or an affordable employer plan ends your Marketplace credit eligibility, and continuing to accept advance payments after that point creates a repayment obligation. A move to a new ZIP code can change the benchmark plan and available prices in your area.
What Happens If You Skip Form 8962
The most common and consequential mistake is failing to file Form 8962 at all. If you received advance credits and don’t reconcile them, the IRS blocks you from receiving advance payments for the following year.13Internal Revenue Service. Reconciling Your Advance Payments of the Premium Tax Credit You’d pay full-price premiums each month and wait until tax time to claim the credit. Many people don’t discover the cutoff until the next open enrollment, when their quoted monthly premium suddenly triples.
Underreporting income is the other pitfall. Because the 400% FPL cliff is back and repayment caps are gone, someone who reported $50,000 but actually earned $65,000 could lose the entire credit and repay every dollar of advance payments with no reduction. The IRS matches your return against W-2s and 1099s, so mismatches surface quickly.
Filing with an uncorrected 1095-A can delay processing and trigger IRS notices. Errors in your favor can shrink the credit you were owed; errors that inflated your credit can produce an unexpected bill later. Keep Marketplace correspondence and tax forms for at least three years, the standard window for amended returns and most audit activity.
Cost-Sharing Reductions and State Mandates
Two related items don’t affect your federal return but are worth knowing. Households up to 250% FPL enrolled in a silver-tier plan may receive cost-sharing reductions that lower deductibles, copays, and out-of-pocket maximums. These are applied by the insurer, don’t appear on your return, and require no reconciliation.
The federal individual mandate penalty ended in 2019, but several states and the District of Columbia impose their own coverage requirements with penalties that generally start around $950 per uninsured adult and can reach $2,800 or more for a family.14Internal Revenue Service. Affordable Care Act Tax Provisions for Individuals and Families Marketplace coverage satisfies those state requirements. Check your state tax authority for the specific rules where you live.
