The premium tax credit: who qualifies and how it works

You qualify for the premium tax credit if you buy a plan through the Health Insurance Marketplace, your household income for the year falls in the range the law allows, and you can’t get affordable coverage through a job or a program like Medicaid, Medicare or CHIP. The credit lowers your monthly premium. You can have it paid to your insurer every month, claim it when you file your taxes, or split it between the two.

Do you qualify for a health insurance subsidy?

Run through this checklist. You need a yes on every line:

• You’ll enroll in a plan through the Marketplace, not directly with an insurance company outside it
• Your household income for the year is at least 100 percent of the federal poverty level for your family size and, for 2026 plans, no more than 400 percent, with a few exceptions at the low end
• You and the family members you’re covering can’t get job-based coverage that counts as affordable and meets minimum value
• You aren’t eligible for Medicaid, Medicare, CHIP or TRICARE
• You won’t file your taxes as married filing separately, apart from narrow exceptions
• No one else can claim you as a dependent
• You meet the Marketplace’s citizenship or immigration status rules

Income here means modified adjusted gross income for the year you want coverage, added up for you, a spouse you file with and any dependents who have to file a return. Last year doesn’t count. It’s your adjusted gross income plus any tax-exempt interest, nontaxable Social Security benefits and excluded foreign income. If you’re self-employed, estimating that number takes a few extra steps.

The quickest check is to enter your household and income estimate and see which plans and credit come back.

How is the credit figured?

The amount starts with the premium for a benchmark plan in your area, the second-lowest-cost silver plan. From that, the law subtracts what your household is expected to pay, a share of your income that rises as income rises. What’s left is your credit.

You can use that credit on any metal level, but not on a catastrophic plan. The dollar amount doesn’t change. On a plan that costs less than the benchmark, it covers more of the premium, sometimes all of it, and on a plan that costs more, you pay the difference.

Say your shortlist has the benchmark silver plan and a bronze plan with a lower premium. The credit is the same on both. On the bronze plan, it covers a larger share of the premium, but the deductible is higher, and the extra savings that lower deductibles and copays for some incomes only come with silver.

Should you take the credit in advance or at tax time?

You choose how much to use each month: all, some or none. The advance part goes straight to your insurer, so your monthly bill drops, and whatever you don’t use in advance you claim when you file your federal return.

Taking all of it in advance keeps your monthly cost lowest, and it fits people whose income is steady and easy to predict. Taking less suits people whose income swings. The tax-time settlement then tends to run in your favor instead of against you. Paying the full premium all year and claiming everything at tax time is allowed too, but you carry the whole cost until you file.

How does the subsidy affect your tax return?

Every advance credit gets settled. Early in the year, the Marketplace sends Form 1095-A showing what was paid on your behalf, and you file Form 8962 with your federal return to compare that with the credit your final income supports. If you used too little, you get the difference as a larger refund or a smaller balance due. If you used too much, you pay it back.

For 2026 on, repayment has no cap. The IRS says you repay the full amount by which the advance credit exceeds the credit you qualify for, and if your final income for 2026 lands above the 400 percent limit, that means all of it. You also have to file a return with Form 8962 attached for any year advance payments were made for you, even if you otherwise wouldn’t need to file.

Is the premium tax credit good or bad?

It’s neither, on its own. It’s money toward your premium that the law provides if you qualify. The part people call bad is the tax-time bill when an income estimate turns out too low, and that risk is manageable: estimate carefully, update the Marketplace when your income changes, and take less than the full credit in advance if your year is hard to predict.

Will premium tax credits be extended?

The larger credits Congress added in 2021 expired at the end of 2025, and 2026 plans went back to the original rules. Congress has debated bringing them back, so check HealthCare.gov for the rules that apply to 2027 plans; it posts 2027 amounts starting November 1. The original credit remains law. The debate is over how large it should be and who should get it.

Open Enrollment for 2027 coverage usually runs November 1 through January 15 on the federal Marketplace, and some states run their own dates. To have coverage start January 1, enroll by December 15.
