The Premium Tax Credit is a direct reduction in what you pay for health insurance each month

The Premium Tax Credit (sometimes called the Advanced Premium Tax Credit or APTC) lowers the monthly cost of health insurance bought through the Health Insurance Marketplace. Instead of paying the full premium to your insurer, you pay a reduced amount, and the credit covers the difference. The credit is based on your household income and the cost of the second-cheapest Silver plan in your area — not on which plan you actually choose.

The credit works in two ways. You can claim it when you file your tax return at the end of the year, or you can use it in advance by telling the Marketplace to send it directly to your insurer each month. Most people use the advance method because it reduces their out-of-pocket costs when ready, rather than waiting for a refund. The amount you receive changes if your income changes during the year, which is why the Marketplace asks you to report changes.

This credit is separate from cost-sharing reductions, which lower your deductible and copays. You can receive both at the same time if you buy a Silver plan and your income qualifies.

Key Takeaways

  • The Premium Tax Credit reduces your monthly insurance payment based on your household income and the cost of the second-cheapest Silver plan available where you live.
  • You can receive the credit in advance each month (most common) or claim it all at once when you file your tax return.
  • Your income must fall between 100% and 400% of the federal poverty line to receive any credit, though some states have extended it higher.
  • You must report changes in income, household size, or other life events to the Marketplace within 30 days, or you may owe money back at tax time.
  • The credit is available only for plans bought through the Health Insurance Marketplace, not for employer coverage or plans bought directly from insurers.

How income determines your credit amount

The Marketplace calculates your credit by comparing your expected household income to the federal poverty line for your family size. The credit is designed so that you pay a percentage of your income toward the second-cheapest Silver plan, and the credit covers the rest. That percentage increases as your income rises — at 100% of poverty, you pay roughly 0% of income; at 400% of poverty, you pay roughly 9.5% of income.

Your household income includes wages, self-employment income, investment income, and certain other sources. It does not include Social Security, Supplemental Security Income (SSI), or certain other benefits. The Marketplace uses your most recent tax return to estimate your income, but you can update this estimate if you expect your income to change — for example, if you lost a job, got married, or had a child.

The federal poverty line changes each year. In 2024, 100% of the poverty line for a single person is approximately $14,600, and for a family of four is approximately $30,000. These figures vary by state and year. If your income is below 100% of the poverty line, you do not receive a credit through the Marketplace, though you may be able to enroll in Medicaid instead.

Advance credit versus claiming it at tax time

When you enroll in a Marketplace plan, you choose whether to use your credit in advance or claim it later. If you choose advance credit, the Marketplace sends money to your insurer each month, and your premium bill is already reduced. You pay only the difference between the full premium and the credit amount. This is the faster way to lower your costs.

If you claim the credit at tax time, you pay the full premium each month and then receive the credit as a refund (or credit against taxes owed) when you file your return. This method is less common because it requires you to cover the full cost upfront, but some people choose it if they expect their income to drop during the year and want to avoid owing money back.

If you use advance credit and your actual income turns out to be higher than you estimated, you may owe some of the credit back when you file your tax return. If your actual income is lower, you may receive a larger refund. This is why reporting income changes to the Marketplace matters — it keeps the advance payments close to what you actually owe.

What happens if your income or household changes

Life changes — job loss, marriage, divorce, birth of a child, moving to a different state — can affect both your credit amount and which plans are available to you. The Marketplace considers these may have access to life events and allows you to report them outside the annual open enrollment period (usually November 1 to January 15). You have 30 days from the date of the change to report it.

If your income drops, reporting it quickly means your credit will increase, lowering your monthly payment. If your income rises, reporting it means your credit will decrease, and you will pay more each month — but you avoid a large bill at tax time. If you do not report changes, your advance credit payments stay the same, and you settle the difference when you file your return.

If your household size changes — for example, a child is born or a family member moves out — this also affects your credit calculation. The Marketplace uses your household size to determine the poverty line threshold, so adding a family member can increase your credit even if your income stays the same.

The difference between Silver plans and other metal levels

The credit amount is calculated using the second-cheapest Silver plan in your area, but you can use the credit to buy any plan — Bronze, Silver, Gold, or Platinum. If you buy a cheaper Bronze plan, you keep the difference as savings. If you buy a more expensive Gold or Platinum plan, you pay the difference out of pocket.

Silver plans are the middle tier and include both the Premium Tax Credit and cost-sharing reductions (lower deductibles and copays) if your income qualifies. If you use your credit to buy a Bronze plan, you get the credit but not the cost-sharing reductions. This is why financial counselors often recommend Silver plans for people with lower incomes — the combination of the credit and cost-sharing reductions can make them the cheapest option overall.

Reconciliation: what you owe or receive at tax time

At the end of the year, you file Form 8962 (Premium Tax Credit Reconciliation Statement) with your tax return. This form compares the advance credit payments you received during the year to the credit you were actually may have access to to based on your final income. If you received more credit than you were may have access to to, you owe the difference back. If you received less, you get a refund.

The amount you owe back is capped depending on your income. In 2024, if your income was below 200% of the poverty line, you owe back no more than $650 (single) or $1,300 (family). If your income was between 200% and 300% of poverty, the cap is $1,300 (single) or $2,600 (family). Above 300% of poverty, there is no cap — you owe back the full difference. These caps change each year.

This is why keeping the Marketplace informed of income changes matters. Small adjustments during the year prevent large surprises at tax time. If you expect a significant income change, you can ask the Marketplace to adjust your advance credit mid-year rather than waiting until you file.

Who cannot use the Premium Tax Credit

You must buy your plan through the Health Insurance Marketplace to use the credit. If you have employer-sponsored insurance, you are not may be able to access for the credit, even if the employer plan is expensive. If you buy a plan directly from an insurer (off-Marketplace), the credit does not explore. Some people with very high incomes — above 400% of the federal poverty line — do not receive a credit, though they can still buy Marketplace plans at full price.

If you are incarcerated, you cannot receive the credit. If you are not a U.S. citizen or national, you must have a may have access to immigration status to be may be able to access. Undocumented immigrants cannot use the credit, though some states have created separate programs for them.

Frequently Asked Questions

Can I get the Premium Tax Credit if I have a job that offers health insurance?

No. If your employer offers coverage that meets minimum standards, you are not may be able to access for the credit, even if the plan is very expensive or has a high deductible. However, if the employer plan costs more than 8.5% of your household income (the affordability threshold), you may be able to decline it and use the credit for a Marketplace plan instead. Check with the Marketplace about your specific situation.

What happens if I don't report a change in income to the Marketplace?

Your advance credit payments stay the same for the rest of the year. When you file your tax return, the Marketplace will compare your actual income to what you reported, and you will owe back any excess credit you received. If the difference is large, this can reduce your refund or result in a tax bill. Reporting changes within 30 days prevents this.

Can I use the Premium Tax Credit for any health plan?

Only for plans bought through the Health Insurance Marketplace. You can use the credit with any metal level (Bronze, Silver, Gold, Platinum), but not with employer plans, plans bought directly from insurers, or short-term plans. The credit is calculated based on the Silver plan, but you choose which plan to buy.

What if my income is below the poverty line?

You do not receive a Premium Tax Credit through the Marketplace. However, you may be able to enroll in Medicaid, which is free or very low-cost coverage. Medicaid rules vary by state. Contact your state Medicaid office or the Marketplace to learn whether you may have access to.

Do I have to use advance credit, or can I wait and claim it on my tax return?

You can choose either method when you enroll. Advance credit reduces your monthly payment when ready, which is why most people use it. Claiming it at tax time means you pay full price each month and receive the credit as a refund later. Choose based on whether you need the monthly savings now or can cover the full premium yourself.
