ACA subsidies explained: who qualifies and how much you save

Short answer: ACA premium tax credits lower your monthly health insurance payment based on your projected annual household income and the cost of coverage in your area. Cost-sharing reductions, which lower your deductible and copays, are only available on Silver-tier Marketplace plans. You apply through the Marketplace; the credit is paid directly to your insurer each month.

Two different kinds of help

Premium tax credits reduce what you pay each month. Cost-sharing reductions reduce what you pay when you actually use care. They are separate programs with separate rules.

Why Silver plans behave differently

Cost-sharing reductions only attach to Silver plans. For a qualifying household, a Silver plan can end up with a lower deductible than a Gold plan while costing less per month. Comparing tiers on premium alone hides this.

How income is counted

The Marketplace uses your projected household income for the coverage year, not last year's tax return. Report changes during the year so your credit stays accurate and you avoid a reconciliation surprise at tax time.

Frequently asked

Who qualifies for an ACA subsidy?

Households whose projected annual income falls within the qualifying range, who are not eligible for affordable job-based coverage or a program like Medicaid or Medicare, and who buy through the Marketplace.

What happens if I earn more than I estimated?

You may have to repay some of the advance premium tax credit when you file your taxes. Updating your income estimate in the Marketplace during the year keeps the gap small.

Do I have to buy a Silver plan to get a subsidy?

No. Premium tax credits apply to any metal tier. Only cost-sharing reductions, the extra help with deductibles and copays, are limited to Silver plans.
