ACA premium tax credits (PTCs) are federal subsidies that reduce your monthly health insurance premium when you buy a plan through the marketplace. The credit amount is based on your income relative to the federal poverty level — households between 100% and 400% FPL qualify, and those above 400% FPL may also qualify through 2025 under the American Rescue Plan expansions.

The Premium Tax Credit (PTC) is a refundable federal tax credit that lowers the cost of health insurance purchased through the ACA marketplace. It was created by the Affordable Care Act and is administered through the federal tax system — you reconcile it on your federal income tax return each year using IRS Form 8962. HealthCare.gov's premium tax credit page and IRS Publication 974 are the authoritative references.
The credit is calculated as the cost of the second-lowest-cost silver plan ('benchmark plan') in your area minus the maximum premium contribution you are required to make, expressed as a percentage of your income. Lower income = smaller required contribution = larger credit. The IRS updates the percentage table annually. In practice, HealthCare.gov's subsidy estimator calculates your credit automatically when you compare plans — you do not need to compute it manually.
You can choose to receive the credit as an advance (applied monthly to reduce your premium) or claim the full amount on your tax return. Most people take it in advance. If your actual income for the year turns out to be higher than your estimate, you will repay some or all of the excess credit on your return. If it is lower (e.g., you had an unexpectedly low-income year), you may receive additional credit. This reconciliation is done on Form 8962. Report income changes to the marketplace mid-year to minimize the year-end adjustment.
The American Rescue Plan (2021) and Inflation Reduction Act (2022) expanded PTCs — eliminating the 400% FPL income cap through 2025. The enhanced subsidies have been extended; check HealthCare.gov for current eligibility thresholds, as legislative status may change.
