How ACA Subsidies Work

Premium tax credits

The premium tax credit caps what you pay for the benchmark (second-lowest-cost Silver) plan at a percentage of your income, on a sliding scale. The lower your income relative to the Federal Poverty Level, the smaller that percentage — and at the low end, the benchmark plan can cost you nothing.

You can take the credit in advance to lower your monthly premium, or claim it at tax time. Because it is based on your estimated annual income, keeping that estimate accurate matters: earn more than expected and you may repay some credit; earn less and you may get more back.

Cost-sharing reductions

If your income is in a lower range and you choose a Silver plan, you may also qualify for cost-sharing reductions — extra help that lowers your deductible, copays, and out-of-pocket maximum. This makes a Silver plan behave more like a Gold or Platinum plan for eligible enrollees.

The practical takeaway: run the numbers before assuming coverage is unaffordable. Many people qualify for far more help than they expect, and the only way to get these savings is through the Marketplace.

Frequently asked questions

How do I know if I qualify for a subsidy?

Subsidies are based on household income relative to the Federal Poverty Level and the cost of the benchmark plan in your area. A subsidy calculator gives a quick estimate.

What if my income changes during the year?

Report changes to the Marketplace so your advance credit adjusts. Otherwise, the difference is reconciled on your tax return.
