What Are ACA Subsidies — And How Much Could You Save?

Key takeaways

• ACA premium subsidies — known officially as advance premium tax credits — are financial help that lowers your monthly health insurance premium.
• Most people qualify for subsidies based on income and household size. In fact, nearly 9 out of 10 people received financial help for plan year 2026.
• ACA subsidies only apply to Marketplace plans. If you buy a plan directly from an insurance company, you won’t be able to use those savings.
• Your subsidy amount depends on your income, household size, and where you live.
• The savings can be significant — the average subsidy is $650 per month.

Health insurance can be expensive. The good news: Many people qualify for financial help that lowers the monthly cost of coverage. These savings are called ACA premium subsidies. And for millions of people, they make Marketplace health plans much more affordable. But what are ACA subsidies in practice, and how do you know if you qualify?

The rules can feel a little confusing. That’s why we’re here to walk you through who’s eligible for ACA subsidies, how income affects your eligibility, and how to estimate how much financial help you might receive.

What are ACA premium subsidies?

An ACA premium subsidy is financial help from the federal government that lowers the monthly cost of a health insurance plan purchased through the Marketplace.

You might also hear it called a premium tax credit. That’s the official term, but the concept is simpler: It’s basically savings on your health insurance premium.

Most people take the subsidy in advance, meaning the savings are applied directly to the monthly cost of the plan. For example, if a plan costs $600 per month and you qualify for a $400 subsidy, you’d pay about $200 each month. The government sends the rest directly to the insurer.

The alternative is to pay the full premium during the year and claim the subsidy when you file your taxes. In that case, you’d pay $600 each month and receive the $4,800 subsidy as a tax credit at tax time.

How much help you receive depends on a few factors, including:

• Your household income
• Your household size
• Where you live
• The cost of plans in your area

Who is eligible for ACA premium subsidies?

The short answer: A lot of people. In fact, nearly 9 out of 10 people who enrolled in Marketplace coverage for plan year 2026 received some level of financial help.

But there are a few basic rules that determine whether you qualify:

• You enroll in a health plan that’s offered through the ACA Marketplace: Subsidies only apply to Marketplace plans, not coverage purchased directly from an insurance company.
• Your household income falls within the eligible range: In most cases, that means your income is too high for Medicaid but still within the range where the Marketplace provides financial help.
• You don’t have access to other affordable coverage: Usually, this means you don’t get health insurance from your employer, your spouse’s employer, or qualify for Medicare.
• You file a federal tax return for the year you receive the subsidy: ACA subsidies are technically tax credits, even though most people receive them as a monthly discount that gets finalized on your tax return later.

How income affects your subsidy eligibility

When it comes to ACA subsidies, your household income is the biggest factor in determining whether you qualify and how much financial help you receive.

The Marketplace measures income using something called the federal poverty level (FPL). It sounds technical, but the idea is simple: The government sets income benchmarks each year based on how many people are in your household, and those numbers help determine subsidy eligibility.

In most cases, you may qualify for an ACA premium subsidy if your household income falls between about 100% and 400% of the federal poverty level for your household size. But what really matters is how that translates into actual income ranges.
