The Premium Tax Credit is a refundable federal tax credit that lowers the cost of health insurance you buy through the Health Insurance Marketplace.1Internal Revenue Service. Premium Tax Credit (PTC) Overview Created by the Affordable Care Act, it can either reduce your monthly premium in real time or increase your refund when you file your taxes. Because it is refundable, it can bring your tax liability below zero and pay you the difference in cash.
For 2026 coverage, several rules that were in place from 2021 through 2025 have expired, so the credit works differently than it did in recent years.
Who Qualifies
Three things determine eligibility: where you buy your insurance, your income, and whether you have access to other qualifying coverage. Your tax filing status matters too.
The coverage itself has to come from the Marketplace. A plan bought directly from an insurer outside the Marketplace does not qualify.2HealthCare.gov. Premium Tax Credit – Glossary
Income Range
Your household income generally must fall between 100 percent and 400 percent of the federal poverty level for your family size.3Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan From 2021 through 2025, Congress temporarily removed that upper cap and let people above 400 percent of FPL qualify when their benchmark premium exceeded a set share of their income. That expansion expired at the end of 2025. For 2026 coverage, the 400 percent ceiling is back unless Congress passes new legislation. For a family of four, that ceiling is approximately $124,800 for the 2026 coverage year.
The income figure used is Modified Adjusted Gross Income, which starts with your adjusted gross income and adds back tax-exempt interest, non-taxable Social Security benefits, and foreign earned income excluded under Form 2555.4Internal Revenue Service. Modified Adjusted Gross Income Supplemental Security Income is not included.5HealthCare.gov. Modified Adjusted Gross Income (MAGI) MAGI covers everyone in your tax household who is required to file, so a spouse’s income counts, and a dependent’s can too.
No Other Qualifying Coverage
You cannot claim the credit if you have access to other minimum essential coverage. That includes Medicare, Medicaid, and CHIP.6eCFR. 45 CFR 155.305 – Eligibility Standards It also includes employer coverage that meets two tests: the plan pays at least 60 percent of average health care costs, and your share of the self-only premium does not exceed a percentage of household income that the IRS resets each year. If both tests are met, the employer plan blocks the credit even when Marketplace coverage would be cheaper for your family.
Filing Status
Married couples must file jointly. The exception is for victims of domestic abuse or spousal abandonment, who can file separately or apply as unmarried and still qualify.7HealthCare.gov. Who’s Included in Your Household Anyone claimed as a dependent on someone else’s return cannot claim the credit.
How the Credit Amount Is Figured
The calculation is anchored to a specific plan: the benchmark plan, which is the second-lowest cost silver plan available in your area.3Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan Your credit equals the benchmark premium minus the amount you are expected to contribute based on your income.
The expected contribution follows a sliding scale. Lower incomes contribute a smaller share, higher incomes a larger one. With the temporary enhancements expired, the statutory base percentages for 2026 are:
- Up to 133 percent FPL: 2.0 percent of household income
- 133 to 150 percent FPL: 3.0 percent rising to 4.0 percent
- 150 to 200 percent FPL: 4.0 percent rising to 6.3 percent
- 200 to 250 percent FPL: 6.3 percent rising to 8.05 percent
- 250 to 300 percent FPL: 8.05 percent rising to 9.5 percent
- 300 to 400 percent FPL: 9.5 percent
These base percentages are adjusted for inflation each year, so the actual 2026 figures may be slightly higher.3Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan Under the enhancements that were in place through 2025, the ceiling was 8.5 percent and the lowest-income enrollees paid nothing.1Internal Revenue Service. Premium Tax Credit (PTC) Overview
You do not have to enroll in the benchmark plan. Your credit is the same dollar amount whether you pick a cheaper bronze plan or a more expensive gold or platinum plan. Choose a cheaper plan and your monthly out-of-pocket cost drops below your expected contribution. Choose a pricier one and you pay the difference yourself.
Two Ways to Take the Credit
You can receive the credit in advance each month or wait and claim the whole thing when you file.
Advance Payments
Most enrollees choose the Advance Premium Tax Credit, which sends monthly payments directly to your insurer to reduce your premium in real time.1Internal Revenue Service. Premium Tax Credit (PTC) Overview You give the Marketplace an estimate of your income for the coming year, and the credit is calculated from that estimate.
The trade-off is exposure to a repayment if your income turns out higher than estimated. Starting with the 2026 tax year, you owe back the full excess with no cap.8IRS. Updates to Questions and Answers About the Premium Tax Credit
Claiming the Full Credit at Tax Time
The alternative is to pay full price each month and claim the whole credit as a refundable credit on your return. This eliminates the risk of overpayment, but it means carrying twelve months of unsubsidized premiums yourself before any relief arrives. It tends to fit people with unpredictable income who want to avoid a surprise tax bill.
What Changed for 2026
Three shifts matter most for anyone comparing 2026 to recent years.
The 400 percent FPL ceiling is back. Income above that line disqualifies you entirely, whereas from 2021 through 2025 higher earners could still qualify if the benchmark premium was expensive enough relative to their income.
Contribution percentages went up across the income scale. The statutory sliding scale replaces the enhanced version that capped everyone at 8.5 percent of income and zeroed out contributions at the low end.
Repayment caps are gone. In prior years, if you received more advance credit than you were entitled to, dollar caps limited how much you owed back, ranging from $350 to $3,000 depending on income and filing status for households below 400 percent FPL. For 2026, those caps are eliminated and you repay the full excess.8IRS. Updates to Questions and Answers About the Premium Tax Credit
The removal of repayment caps makes accurate income estimation far more important for 2026 than it was in recent years. Even a modest underestimate can produce a meaningful tax bill.
Reconciling at Tax Time
Everyone with Marketplace coverage during the year has to reconcile the credit on their federal return, whether they took advance payments or plan to claim the full amount at year end.9eCFR. 26 CFR 1.36B-4 – Reconciling the Premium Tax Credit With Advance Credit Payments
By mid-February, the Marketplace mails Form 1095-A, which lists your monthly premiums, your area’s benchmark premium, and any advance payments made on your behalf.10HealthCare.gov. How to Use Form 1095-A, Health Insurance Marketplace Statement You use those numbers to complete Form 8962, which you file with your return.11Internal Revenue Service. Form 1095-A, Health Insurance Marketplace Statement Form 8962 compares your advance payments to the credit you actually qualify for based on your final year-end income.
If your actual income was lower than estimated, you qualify for a larger credit and the difference comes back to you in your refund. If your income was higher, you must pay the excess back. For 2026, there is no cap on that repayment.
If you received advance payments and do not file a return with Form 8962, the Marketplace may cut off your advance payments in future years, leaving you responsible for the full unsubsidized premium.12Internal Revenue Service. Premium Tax Credit – Claiming the Credit and Reconciling Advance Credit Payments You may also be required to repay some or all of the advance payments you already received. Filing and reconciling, even when you owe money, protects your ability to keep getting advance payments the following year.
Reporting Changes During the Year
If you take advance payments, any shift in your income or household changes the credit you qualify for. Report changes to the Marketplace as soon as they happen so it can adjust your monthly amount.13HealthCare.gov. Reporting Income, Household, and Other Changes If you do not, advance payments keep flowing at the old level and you owe the difference at tax time.
Changes to report include:14HealthCare.gov. Which Income and Household Changes to Report
- Income changes, such as a raise, job loss, or new job
- Household changes, including marriage, divorce, birth or adoption, a dependent turning 26, or a death
- Coverage changes, including a new offer of employer insurance (even if declined), gaining Medicare or Medicaid, or losing existing coverage
- Address changes, since a new ZIP code or county can shift the available plans and benchmark price
- Status changes affecting citizenship, immigration, disability, filing status, or incarceration
Some of these events also open a Special Enrollment Period so you can switch plans outside open enrollment.15CMS. Report Life Changes When You Have Marketplace Coverage
