The ACA premium tax credit is a federal tax credit that lowers the monthly price of a health plan bought through HealthCare.gov or a state exchange. It equals the price of a benchmark silver plan minus the amount you are expected to pay based on your income. For 2026 and 2027 coverage, you generally need household income from 100% to 400% of the federal poverty level to qualify.

That 400% limit is new again. From 2021 through 2025, “enhanced” credits removed the upper income limit and lowered what everyone paid. Those enhancements expired after December 31, 2025, and as of October 18, 2026, no extension had become law. This guide explains how the credit works now, with the IRS figures for 2026 and 2027, how advance payments work, and how to avoid a big bill at tax time.

Did the enhanced premium tax credits expire?

Yes. The enhanced credits, created by the American Rescue Plan Act in 2021 and extended through 2025, ended after December 31, 2025. As of October 18, 2026, Congress had not enacted an extension, and the official figures reflect the original ACA rules:

  • IRS Rev. Proc. 2025-25 sets the 2026 expected contribution from 2.10% to 9.96% of income, ending at 400% of the poverty level. Under the enhanced rules, expected contributions were lower at every income level and there was no 400% cut-off.
  • IRS Rev. Proc. 2026-26, released in July 2026, sets the 2027 range at 2.15% to 10.22%.
  • The IRS premium tax credit Q&A says the removal of the 400% limit was temporary, for tax years 2021 through 2025.
  • HealthCare.gov’s poverty level page says that with income between 100% and 400% of the poverty level you qualify for the credit in all states.

How is the premium tax credit calculated?

The formula has three steps:

  1. Find your income as a percentage of the federal poverty level (FPL). Use your expected household income for the coverage year and the poverty guideline for your household size. Our FPL calculator does this for you.
  2. Find your expected contribution. The IRS table gives a percentage of income for your FPL band. Within a band, the percentage rises gradually with income.
  3. Subtract. Credit = benchmark plan premium − expected contribution. If the result is zero or less, you get no credit.

What is the benchmark plan?

The benchmark is the second-lowest-cost silver plan (SLCSP) available to your household in your area. Its price depends on your age, location and household. You do not have to buy it. The credit is a dollar amount that you can apply to any bronze, silver, gold or platinum Marketplace plan, but not to a catastrophic plan.

Because the credit is a fixed amount, cheaper plans get cheaper by the same dollar figure. To see real plans and prices in your county with the estimated credit applied, use our ACA subsidy calculator or the ACA plan finder.

Who qualifies for the premium tax credit?

In general, you may qualify if all of these are true:

  • You buy a plan through HealthCare.gov or your state’s exchange.
  • Your household income is from 100% to 400% of the FPL for your family size.
  • You are not eligible for other qualifying coverage, such as Medicaid, Medicare, or an affordable job-based plan that meets minimum value.
  • You file a federal tax return, and if married, you generally file jointly.
  • You cannot be claimed as someone else’s dependent.

The 400% cliff for 2026 and 2027

Because the 400% limit is back, a small raise can end the credit entirely. These are the cut-offs in the 48 contiguous states and DC.

Household size400% FPL for 2026 coverage (2025 guidelines)400% FPL for 2027 coverage (2026 guidelines)
1$62,600$63,840
2$84,600$86,560
3$106,600$109,280
4$128,600$132,000

Figures are four times the poverty guidelines published by HealthCare.gov and HHS (Federal Register, January 15, 2026). Alaska and Hawaii have higher guidelines.

Affordable job-based coverage

If you can get job-based coverage that is “affordable” and meets minimum value, you generally cannot get the credit. For 2026, employee-only coverage is affordable if it costs no more than 9.96% of household income; for 2027, no more than 10.22% (IRS required contribution percentage).

Other 2026 changes from the 2025 tax law

The 2025 tax law (Public Law 119-21, also called the One Big Beautiful Bill Act) changed several credit rules. According to IRS proposed regulations scheduled for publication on October 15, 2026:

  • From 2026, lawfully present immigrants with income below 100% of FPL who cannot get Medicaid because of their status are no longer eligible for the credit.
  • For plan years after 2025, a plan you enroll in through a Special Enrollment Period based only on a change in expected income does not count for the credit. See our Special Enrollment Period guide.
  • For tax years after 2025, the limits on repaying excess advance credit are gone (see below).

Advance payments vs claiming at tax time

You choose how to take the credit when you enroll. HealthCare.gov lets you use all, some or none of it each month.

OptionHow it worksGood forRisk
All in advancePaid to your insurer monthly; your bill drops right awaySteady, predictable incomeOwe money back if income rises
Part in advanceTake a portion monthly; claim the rest when you fileVariable or uncertain incomeHigher monthly bills
None in advancePay the full premium; claim the full credit on your tax returnVery uncertain incomeHighest monthly cost

Report changes in income or household size to the Marketplace during the year. HealthCare.gov says that if your income goes up, you will probably qualify for less credit, and you may want to use less of it each month.

How does Form 8962 reconciliation work?

If anyone in your tax household had Marketplace coverage with advance payments, you must file a federal return and attach IRS Form 8962. You use Form 1095-A, which the Marketplace sends early in the year, to fill it in.

  1. Form 8962 figures the credit you actually qualify for, using your final income and the benchmark premium shown on Form 1095-A.
  2. It compares that number with the advance payments made for you.
  3. If you got too little, the difference increases your refund or lowers the tax you owe.
  4. If you got too much, you repay the excess with your return.

No repayment cap starting with 2026

For tax years before 2026, a cap limited how much many people had to repay. The IRS says that for tax years after 2025, you must repay the full amount by which your advance payments exceed your credit. If your income ends above 400% of FPL, you repay all of the advance credit for that year.

What if you don’t file and reconcile?

Federal law requires you to file and reconcile if you received advance credit. On July 22, 2026, after court rulings, CMS told exchanges to stop removing or denying advance credit for 2026 and 2027 coverage because someone failed to file and reconcile in prior years. CMS stressed that this does not change the legal requirement to file and reconcile. Skipping it can still lead to problems with the IRS.

How does the credit work for a family?

For a family, the steps are the same, but the numbers change in two ways. First, the poverty guideline is larger for a bigger household, so the same income is a lower FPL percentage. Second, the benchmark premium is the price of the second-lowest-cost silver plan that would cover everyone who is enrolling, which is usually much higher than for one person.

Children are often eligible for Medicaid or CHIP at incomes where their parents qualify for the credit. If a child qualifies for one of those programs, the child is generally not counted for the credit, and the Marketplace application will tell you.

Common mistakes to avoid

  • Using last year’s income without thinking ahead. The credit is based on what you expect for the coverage year.
  • Forgetting household members. Count yourself, a spouse and everyone you claim as a dependent.
  • Not reporting a raise or new job. For 2026 and later there is no repayment cap.
  • Ignoring a job-based offer. An affordable offer usually blocks the credit, even if you do not take it.
  • Skipping silver when your income is under 250% of FPL. You may be missing cost-sharing reductions, which only come with silver plans. Our guide to ACA metal levels explains the trade-offs.
