What the Premium Tax Credit Does

The Premium Tax Credit is a federal payment that lowers the monthly cost of health insurance bought through the Health Insurance Marketplace. The government sends the money directly to your insurance company each month, reducing what you pay out of pocket. You do not have to wait until tax time — the credit works immediately when you enroll.

The credit is based on your household income and the cost of the second-cheapest Silver plan in your area. If you earn between 100% and 400% of the federal poverty line, you may be able to use this credit. The exact amount you receive depends on what you actually earn, not what you estimate.

This is different from a tax refund. The credit is advance payment for a tax benefit you are may have access to to based on your income. When you file taxes the following year, the IRS reconciles what you received during the year against what you were actually owed, and you either get money back or owe a small amount.

Key Takeaways

  • The Premium Tax Credit pays your insurance company directly each month, so your monthly bill is lower from the start.
  • You must enroll through Healthcare.gov or your state's Marketplace to receive the credit — plans bought outside the Marketplace do not may have access to.
  • The amount you receive is based on your household income, and you must report income changes within 30 days to avoid overpayment.
  • When you file taxes, the IRS compares what you received to what you were owed based on your actual income, and you may owe money back if you earned more than expected.
  • You can change your income estimate or coverage during the year if your circumstances change, and the credit adjusts automatically.

How Your Income Determines the Credit Amount

The credit is calculated using your household income and comparing it to the cost of the second-cheapest Silver plan available in your zip code. The government pays the difference between that benchmark plan cost and a percentage of your income that increases as your income rises.

At 100% of the federal poverty line, you pay roughly 2% of your income toward the benchmark plan. At 400% of the poverty line, you pay roughly 8.5%. The poverty line amounts change each year — for 2024, 100% of the poverty line for a single person is about $15,060 per year, and for a family of four is about $31,200 per year. These figures are updated annually.

Your household income includes wages, self-employment income, Social Security, unemployment benefits, and other sources. It does not include certain items like child support received or tax-exempt interest. If you are unsure whether something counts, the Marketplace application will ask about it directly.

Where to Enroll and What Documents You Need

You enroll through Healthcare.gov if you live in a state that uses the federal Marketplace, or through your state's own Marketplace if your state runs one. A few states — California, Connecticut, Delaware, Maryland, Minnesota, Missouri, New Mexico, New York, Rhode Island, and Washington — operate their own systems. You can find your state's site through Healthcare.gov.

During enrollment, you will need to provide your Social Security number, citizenship or immigration status, and current household income. You do not need to upload documents at the time of enrollment, but you should have recent pay stubs, tax returns, or other income records available. The Marketplace may ask you to verify information later, and having documents ready speeds up that process.

Open enrollment runs from November 1 to January 15 each year. If you miss that window, you can still enroll if you have a may have access to life event — losing health coverage, getting married, having a baby, moving to a new state, or a significant income change. You have 60 days from the event to enroll.

Reporting Income Changes and Avoiding Overpayment

The credit is based on your expected income for the year. If your actual income ends up higher than you estimated, you may have received more credit than you were owed, and you will owe some of it back when you file taxes. If your income is lower, you may be owed additional credit.

You should report changes within 30 days of when they happen. If you lose a job, get a raise, start self-employment income, or have any other change that affects your household income, log into your Marketplace account and update your information. The credit will adjust automatically for the following month.

If you do not report a change and your income rises significantly, you could owe back a substantial amount at tax time. The IRS limits how much you have to repay if you are below 400% of the poverty line — the cap ranges from $300 to $2,700 depending on your filing status — but you still owe something. Reporting changes as they happen prevents this problem.

What Happens at Tax Time

When you file your federal tax return, you will receive a form called the 1095-B from your insurance company showing you had coverage, and a form called the 1095-A from the Marketplace showing how much Premium Tax Credit you received during the year.

You use the 1095-A to reconcile the credit. You report the credit you actually received and your actual household income for the year. The IRS calculates what you should have received based on your real income and compares it to what you got. If you received more, you owe the difference. If you received less, you get the additional amount as a refund or credit against other taxes owed.

This reconciliation happens automatically if you file taxes. If you do not file, the IRS will not pursue the overpayment, but you also will not receive any refund you might be owed. Most people who receive the credit should file taxes even if they would not otherwise be required to, because the reconciliation determines whether they owe money.

The Relationship Between the Credit and Your Tax Refund

The Premium Tax Credit is separate from your overall tax refund or tax bill. The credit reduces what you owe for health insurance, but it does not change how much federal income tax you owe based on your wages and other income.

If you overpaid the Premium Tax Credit during the year and also overpaid your income taxes, both amounts can be combined into a single refund. If you underpaid the credit and also owe income taxes, both amounts are added together and you owe the total. The credit and your income tax situation are reconciled together on your return.

Frequently Asked Questions

What if I do not know my exact income when I enroll?

You provide your best estimate based on what you expect to earn that year. If your situation is uncertain — you are self-employed, recently changed jobs, or have variable income — estimate conservatively and plan to update it if your actual income changes. You can update your estimate anytime during the year through your Marketplace account.

Can I use the Premium Tax Credit with a plan outside the Marketplace?

No. The credit only works with plans sold through Healthcare.gov or your state's Marketplace. Plans bought directly from an insurance company or through a broker do not may have access to, even if they are the same plan offered on the Marketplace. You must enroll through the official Marketplace to receive the credit.

What if I get married or have a baby during the year?

These are may have access to life events. You have 60 days from the event to enroll or change your coverage. When you report the change, update your household size and income, and your credit amount will adjust. If you have a baby, you can add them to your plan immediately or enroll them in a separate plan.

Do I have to repay the entire credit if my income is higher than expected?

Not necessarily. If your income is below 400% of the federal poverty line, the IRS caps how much you have to repay — between $300 and $2,700 depending on your filing status. Above 400% of the poverty line, you repay the full overpayment with no cap. This is why reporting income changes promptly matters.

What if I do not file taxes?

The IRS will not pursue you for overpayment of the credit if you do not file. However, you also will not receive any refund you might be owed, and you will not resolve the reconciliation. Most people who receive the credit should file taxes to settle the account, even if they would not otherwise be required to file.
