A federal tax credit is a dollar-for-dollar reduction in the income tax you owe to the U.S. government

When you file your federal income tax return, the IRS calculates how much tax you owe based on your income. A tax credit is different from a deduction: instead of reducing the income that gets taxed, a credit directly subtracts from the final tax bill itself. If you owe $2,000 in federal income tax and you have a $500 tax credit, you now owe $1,500. The credit is worth its full dollar amount, no matter what tax bracket you are in.

The federal government offers dozens of different credits, each designed to encourage or support specific situations—having children, going to school, buying an electric vehicle, installing solar panels, or earning a low income. Some credits are refundable, meaning if the credit is larger than the tax you owe, the IRS sends you the difference as a refund. Others are non-refundable, meaning they can only reduce your tax bill to zero, not below it.

Key Takeaways

  • A tax credit directly reduces the amount of federal income tax you owe, dollar for dollar, which makes it more valuable than a deduction of the same size.
  • Refundable credits can result in a refund if they exceed your tax bill, while non-refundable credits can only reduce what you owe down to zero.
  • Common credits include the Earned Income Tax Credit (EITC) for low to moderate earners, the Child Tax Credit for parents, and education credits for students and their families.
  • You claim tax credits on your federal tax return by filling out specific forms and schedules, which you submit to the IRS when you file.

How a tax credit differs from a tax deduction

A deduction reduces your taxable income—the amount of money the IRS taxes. A credit reduces your tax bill itself. The difference matters. If you are in the 22% tax bracket and you have a $1,000 deduction, you save $220 in taxes. If you have a $1,000 credit, you save the full $1,000. Credits are always worth more than deductions of the same dollar amount.

For example: you earn $50,000 and owe $6,000 in federal income tax. A $1,000 deduction would lower your taxable income to $49,000 and reduce your tax bill by roughly $220. A $1,000 credit would reduce your tax bill directly from $6,000 to $5,000. That is why tax credits are so valuable to the people who can claim them.

Refundable versus non-refundable credits

A refundable credit can give you money back even if you do not owe any tax. If the credit is larger than your tax bill, the IRS sends you the excess as a refund. The Earned Income Tax Credit (EITC) is the most common refundable credit—many low-income workers owe zero federal tax but still receive a refund because their EITC is larger than zero.

A non-refundable credit can only reduce your tax bill to zero. If the credit is larger than what you owe, you lose the unused portion—the IRS does not send it to you. The Child and Dependent Care Credit is non-refundable, as is the Lifetime Learning Credit. You can carry some non-refundable credits forward to future tax years, but not all of them.

When you file your return, the IRS applies non-refundable credits first, then refundable credits. This matters if you have both types: the non-refundable credit reduces your bill, and then the refundable credit is applied to whatever remains.

Common federal tax credits and who can claim them

The Earned Income Tax Credit (EITC) is a refundable credit for workers with low to moderate income. The amount depends on your income, filing status, and number of may have access to children. For 2024, the maximum credit ranges from about $600 for workers without children to over $3,900 for workers with three or more children. You must have earned income to claim it.

The Child Tax Credit is worth up to $2,000 per child under age 17. It is partially refundable—up to $1,700 of the credit can be refunded to you if you do not owe enough tax to use the full amount. You must be the child's parent or legal guardian and claim them as a dependent.

The American Opportunity Tax Credit helps pay for college. It is worth up to $2,500 per student per year and is partially refundable (up to $1,000 can be refunded). You claim it for a student in their first four years of college, and the student must be pursuing a degree or other recognized credential.

The Lifetime Learning Credit is also for education and is worth up to $2,000 per return (not per student). It is non-refundable and covers tuition and fees for any level of education, including graduate school and professional development courses.

The Saver's Credit (Retirement Savings Contributions Credit) is for low to moderate-income workers who contribute to a retirement account. It is worth up to $1,000 and is non-refundable. You must have earned income and meet income limits.

The Residential Energy Credits cover the cost of installing energy-efficient improvements to your home, such as solar panels, heat pumps, or insulation. These credits are non-refundable and can be carried forward to future years if you do not owe enough tax to use them in the current year.

How to claim a tax credit on your return

You claim tax credits by filling out specific forms and schedules when you file your federal income tax return. The form you need depends on which credit you are claiming. For example, you use Schedule EIC to claim the Earned Income Tax Credit, Form 8863 for education credits, and Form 5695 for residential energy credits. The IRS website lists which form goes with which credit.

If you use tax software (such as TurboTax, H&R Block, or the IRS Free File program), the software will ask you questions about your situation and automatically generate the correct forms. If you file by hand or work with a tax preparer, you need to know which credits you are may be able to access for and provide the necessary documentation—such as a Form 1098-T from your school or receipts for energy improvements.

You submit the completed forms and schedules along with your main tax return (Form 1040) to the IRS. If you are filing electronically, the software handles this. If you are mailing a paper return, include all forms in the correct order as listed in the Form 1040 instructions.

Income limits and other restrictions on tax credits

Most federal tax credits have income limits. If your income is above the limit, you cannot claim the credit at all. Some credits phase out gradually—meaning the credit amount shrinks as your income rises above a certain threshold. The EITC, Child Tax Credit, and education credits all have income limits that vary by filing status (single, married filing jointly, head of household, etc.).

Other credits have restrictions based on your situation. The American Opportunity Credit requires the student to be enrolled at least half-time in a degree program. The Residential Energy Credits require you to own the home and have the work done by a contractor (in most cases). The Saver's Credit requires you to have earned income and meet age and filing status requirements.

The IRS publishes income limits and may be able to access rules for each credit in the instructions that come with the relevant form. You can also find this information on the IRS website or by speaking with a tax preparer.

What happens if you claim a credit you are not may have access to to

If you claim a tax credit on your return and the IRS determines you were not may have access to to it, they will adjust your return and send you a bill for the additional tax owed, plus interest. If the error was unintentional, you may also face a penalty, though the IRS sometimes waives penalties for first-time mistakes or reasonable cause.

If you intentionally claim a credit you know you do not may have access to for, that is tax fraud. The IRS can pursue civil penalties (fines) and, in serious cases, criminal prosecution. It is important to be honest about your situation when you file and to keep records that support the credits you claim—such as receipts, school documents, or proof of income.

Frequently Asked Questions

Can I claim more than one tax credit on the same return?

Yes. You can claim multiple credits if you meet the requirements for each one. For example, you can claim both the Child Tax Credit and the Earned Income Tax Credit on the same return. The IRS applies them in a specific order, and some credits may reduce the value of others, so the total benefit is not always the sum of the individual credits.

What is the difference between a tax credit and a tax deduction?

A deduction reduces your taxable income, while a credit reduces your tax bill directly. A $1,000 deduction saves you money based on your tax bracket (usually $100 to $370). A $1,000 credit saves you the full $1,000. Credits are worth more than deductions of the same size.

Can I get a refund if my tax credit is larger than what I owe?

Only if the credit is refundable. Refundable credits like the EITC and the refundable portion of the Child Tax Credit can result in a refund if they exceed your tax bill. Non-refundable credits can only reduce your bill to zero; any unused amount is lost (though some can be carried to future years).

Do I need to file a tax return to claim a tax credit?

Yes. You must file a federal income tax return to claim any tax credit. Even if you have no tax liability, you may want to file to claim a refundable credit like the EITC, which can result in a refund. The IRS Free File program offers free filing for may be able to access taxpayers.

What records do I need to keep to support a tax credit claim?

Keep receipts, invoices, and documentation related to the credit you are claiming. For education credits, keep your Form 1098-T from your school. For energy credits, keep contractor invoices and receipts. For the EITC or Child Tax Credit, keep proof of income and documents showing your relationship to dependents. Keep these records for at least three years.
