A federal tax credit reduces the actual tax you owe to the IRS, dollar for dollar

A federal tax credit is money the government subtracts directly from your tax bill. If you owe $2,000 in federal income tax and you have a $1,500 tax credit, you pay $500. This is different from a deduction, which only reduces the income the IRS counts — a $1,500 deduction might save you $300 or $400 depending on your tax bracket, but a $1,500 credit saves you the full $1,500.

The IRS offers dozens of federal tax credits for different situations: having children, paying for childcare, going to school, installing solar panels, buying an electric vehicle, or earning a low income. You claim them on your tax return when you file. Some credits are refundable, meaning if the credit is larger than what you owe, the IRS sends you the difference. Others are non-refundable, meaning they can only reduce your bill to zero — you do not get money back if the credit is bigger.

Key Takeaways

  • A tax credit subtracts directly from the tax you owe, while a deduction only reduces your taxable income.
  • Refundable credits can result in a refund if they exceed what you owe; non-refundable credits can only bring your bill down to zero.
  • You claim tax credits on your federal tax return (Form 1040 and related schedules) when you file with the IRS.
  • Common federal credits include the Earned Income Tax Credit (EITC), Child Tax Credit, American Opportunity Tax Credit, and Lifetime Learning Credit.

Refundable versus non-refundable credits

A refundable credit works like a payment to you. If you owe $800 in tax and you have a $1,200 refundable credit, the IRS pays you $400. The Earned Income Tax Credit (EITC) and the Child Tax Credit (up to a certain amount) are refundable. This matters most to people with low or moderate income who may owe little or no tax — the credit can still put money in their pocket.

A non-refundable credit can only reduce your tax bill to zero. If you owe $800 and you have a $1,200 non-refundable credit, you pay zero tax, but you do not receive the extra $400. The American Opportunity Tax Credit and Lifetime Learning Credit are non-refundable (though the American Opportunity Credit has a partial refund component). The value of a non-refundable credit depends on how much tax you actually owe.

How to claim a federal tax credit on your return

You claim federal tax credits by filing a federal income tax return with the IRS, even if you do not normally have to file. Most people file using Form 1040 (the main income tax form) plus additional schedules that match the credit. For example, the Child Tax Credit uses Schedule 8812, and education credits use Form 8863.

If you use tax software (like TurboTax, H&R Block, or IRS Free File), the software walks you through questions about your situation and automatically fills in the right forms. If you file on paper or with a tax professional, you or your preparer will complete the forms by hand. The IRS publishes instructions for each form on its website at irs.gov. You file your return by the annual deadline, usually April 15, though you can request an extension.

Some credits require you to meet conditions throughout the year. For example, to claim the Child Tax Credit, the child must live with you for more than half the year and be under age 17 at the end of the year. To claim education credits, you must have paid tuition and fees at an accredited school. Keep records — receipts, school statements, proof of childcare expenses — in case the IRS asks for documentation later.

Common federal tax credits and who they are for

The Earned Income Tax Credit (EITC) is for people with low to moderate income from work. The amount depends on your income, filing status, and number of children. In 2024, a single person with no children could receive up to $600; a married couple with three children could receive up to $3,995. The EITC is refundable, so many people receive a refund even if they owe no tax.

The Child Tax Credit provides up to $2,000 per child under age 17. You must claim the child as a dependent on your return. Part of this credit (up to $1,700 per child) is refundable, so families with low income may receive a refund. The credit phases out at higher income levels.

The American Opportunity Tax Credit covers education costs for students in their first four years of college or university. You can claim up to $2,500 per student per year for tuition, fees, and course materials. Up to $1,000 of this credit is refundable. The Lifetime Learning Credit covers tuition and fees for any year of college or graduate school and is up to $2,000 per return (not per student), but it is non-refundable.

The Child and Dependent Care Credit helps pay for childcare or adult dependent care so you can work. You can claim up to $3,000 in expenses per year (or $6,000 for two or more dependents). The credit is 20 to 35 percent of those expenses, depending on your income. The Adoption Credit covers adoption expenses and is up to $15,000 per child (the amount changes yearly).

Income limits and phase-outs

Most federal tax credits have income limits. If your income is too high, you cannot claim the credit, or the amount you can claim shrinks. These limits change every year because they are adjusted for inflation. For example, the Child Tax Credit begins to phase out at $400,000 of income for married couples filing jointly in 2024, but that threshold is different for single filers and changes annually.

You calculate your income using your Adjusted Gross Income (AGI), which appears on your tax return. If you are close to an income limit, it is worth calculating your exact AGI before you file, because even a small change — like a deduction you missed or a small amount of additional income — can affect whether you may have access to for the full credit, a reduced credit, or no credit at all.

Tax credits versus tax deductions

The difference between a credit and a deduction matters to your wallet. A deduction reduces the income the IRS counts as taxable. If you earn $50,000 and you have a $5,000 deduction, the IRS counts only $45,000. If your tax rate is 22 percent, that deduction saves you $1,100. A $5,000 credit saves you the full $5,000, no matter your tax rate.

Deductions are useful if you have high income and a high tax rate. Credits are more valuable if you have low or moderate income. Many people can claim both — for example, you might deduct student loan interest and also claim an education credit for the same student in the same year, though some combinations have limits.

Frequently Asked Questions

Can I claim a tax credit if I do not owe any federal income tax?

It depends on whether the credit is refundable. A refundable credit can result in a refund even if you owe zero tax. The EITC and part of the Child Tax Credit are refundable, so you may receive money back. A non-refundable credit can only reduce your bill to zero — it cannot produce a refund.

What happens if I claim a tax credit I do not actually may have access to for?

The IRS may audit your return and ask for proof that you met the requirements. If you cannot provide it, you will have to repay the credit plus interest and possibly penalties. Keep records of expenses, school enrollment, childcare payments, and anything else the credit requires.

Can I claim the same credit more than once in one year?

No. You claim each credit once per tax year. However, you can claim multiple different credits on the same return — for example, the EITC and the Child Tax Credit together. Some credits have limits on how many times you can claim them across multiple years (like the American Opportunity Credit, which is limited to four years per student).

Do I need to file a tax return to get a refundable tax credit?

Yes. Even if you have no income or your income is very low, you must file a federal tax return to claim a refundable credit like the EITC or the refundable portion of the Child Tax Credit. The IRS does not send you money without a return on file.
