What is APTC? The advance premium tax credit in plain words
In short: APTC (advance premium tax credit) is government help that lowers your monthly health insurance premium. You can only get it for a plan from your state's official Health Insurance Marketplace (HealthCare.gov or your state's own site). It is based on the income you expect for the year, so tell the marketplace when your income or household changes, or you may have to pay some back.
What the words mean
- Premium: what a health plan costs each month.
- Premium tax credit: help with that cost, set by law.
- Advance: instead of waiting until you file taxes, the help is paid straight to your insurer every month, so your bill is lower now.
Who can get it
The marketplace works it out for you when you apply. It looks at:
- The income your household expects for the year, and how many people are in it.
- The price of a benchmark Silver plan where you live.
- Whether you can get other affordable cover, such as a job-based plan, Medicaid or Medicare.
The extra help of 2021 to 2025 has ended. Since 2026, households earning more than 400% of the federal poverty level usually do not qualify, and amounts are smaller for many people. The marketplace shows your exact amount before you choose a plan.
How to use it well
- Apply on the official site for your state. Use our marketplace finder to open it.
- Estimate your income carefully. You can take all of the credit in advance, some of it, or none.
- Report changes straight away: a new job, a raise, a lost job, a marriage or a new baby.
- Keep Form 1095-A. The marketplace sends it early in the year. You need it when you file your federal tax return.
If your income changes
At tax time, the credit you got in advance is compared with the credit you were due for your real income. If you got too little, you may get the difference back. If you got too much, you may have to pay the extra back, and since 2026 there is no cap on how much. This site does not give tax advice: the IRS explains the rules, and a tax professional can help.
Cost-sharing reductions are different
APTC lowers the premium. If your income is low enough, a Silver plan can also lower your deductible and copays. These are called cost-sharing reductions, and you only get them on a Silver plan.
Watch out for scams
- Applying is free. Never pay anyone to "get your subsidy".
- Ads and sites that promise "$0 plans" or "free cash cards" are often run by sellers. Check you are on HealthCare.gov or your state's official site.
- Never give your bank or card details to someone who calls you.
Handy tools
- Health insurance marketplace by state: your state's official site, 2027 dates, helplines and a deductible explainer.
