How the advance premium tax credit works
When you enroll in Marketplace coverage, you estimate your household income and family size for the year. That estimate is used to calculate your expected premium tax credit; the Marketplace then sends the advance payments you qualify for directly to your insurance company each month, lowering what you owe out of pocket.
APTC vs. the premium tax credit: what’s the difference
| Term | What it means |
|---|---|
| Advance Premium Tax Credit (APTC) | Estimated credit paid monthly to your insurer during the year |
| Premium Tax Credit (PTC) | Your actual credit amount, calculated at tax filing based on final income |
Reconciling APTC with Form 1095-A and Form 8962
Your Marketplace sends Form 1095-A by early February showing:
- Your monthly premium
- The second lowest cost Silver plan (SLCSP) amount (a benchmark plan the Marketplace uses to calculate your credit, regardless of which plan you actually enrolled in)
- How much APTC was paid on your behalf
You use those numbers to fill out Form 8962, which compares your APTC to your actual PTC based on your final income for the year.
Do you have to pay back excess APTC?
If your final income came in higher than you estimated, your actual credit may be smaller than what the Marketplace paid out, and you’ll owe the difference. Repayment is capped at a set dollar amount for household income under 400% of the federal poverty line, but there’s no cap above that threshold, so a big income jump can mean repaying the full excess.
For example, you received $3,600 in APTC over the year, but based on your actual income you only qualified for $3,000, so you owe the $600 difference.
Reporting income and life changes to avoid a surprise repayment
Notify the Marketplace as soon as your income, family size, or you gain or lose government- or employer-sponsored health care coverage, or any physical address changes during the year. Updating your estimate adjusts your APTC in real time, so you can minimize repayment when you file.
