A tax credit cuts your tax bill dollar for dollar

A tax credit is money the government subtracts directly from the amount of tax you owe. If you owe $2,000 in federal income tax and you have a $500 tax credit, you now owe $1,500. A credit is not the same as a deduction — a deduction reduces your income before tax is calculated, so it saves you only a portion of what it's worth. A credit saves you the full amount.

Tax credits exist for specific situations: having children, paying for education, installing solar panels, or earning below a certain income level. The IRS publishes the list of available credits each year, and you claim them on your tax return by filling out the matching form or schedule.

Some credits are refundable, meaning if the credit is larger than what you owe, the IRS sends you the difference as a refund. Others are non-refundable, meaning the credit can reduce your bill to zero but not below. A few credits are partially refundable — they work like a refundable credit up to a limit, then stop.

Key Takeaways

  • A tax credit subtracts directly from your tax bill, while a deduction reduces your income before tax is calculated, making credits more valuable.
  • Refundable credits can result in a refund if they exceed what you owe; non-refundable credits can only reduce your bill to zero.
  • You claim a credit by filing the correct form or schedule with your tax return, and the IRS will not automatically include it.
  • Common credits include the Child Tax Credit, Earned Income Tax Credit, and education credits, each with its own income limits and requirements.

Refundable versus non-refundable credits

The difference between refundable and non-refundable credits determines whether you walk away with money or straightforward pay less. A refundable credit works like this: you owe $800, but you have a $1,200 refundable credit. The IRS subtracts $800 from what you owe, bringing it to zero, then sends you the remaining $400 as a refund check or direct deposit.

A non-refundable credit stops at zero. You owe $800, and you have a $1,200 non-refundable credit. The IRS subtracts $800, your bill becomes zero, and the extra $400 credit disappears — you do not receive it. The Earned Income Tax Credit (EITC) is refundable, which is why it often results in large refunds for lower-income workers. The Child Tax Credit is partially refundable: up to $1,700 of the credit can be refunded per child, but the rest is non-refundable.

When you file your return, you need to know which type of credit you are claiming. The IRS form or schedule for each credit will tell you whether it is refundable or non-refundable.

How credits differ from deductions

A deduction lowers your taxable income, not your tax bill directly. If you earn $60,000 and take a $10,000 deduction, your taxable income becomes $50,000. Your tax is then calculated on $50,000 instead of $60,000. The amount you save depends on your tax bracket — if you are in the 22% bracket, a $10,000 deduction saves you $2,200.

A credit skips that step and goes straight to your bill. A $2,200 credit saves you $2,200 no matter what your tax bracket is. This is why a credit is almost always worth more than a deduction of the same dollar amount. The only exception is if you have a very large deduction that pushes you into a lower tax bracket, but that is rare and the math is complex.

The standard deduction (the amount most people subtract from their income automatically) is separate from tax credits. You can use the standard deduction and still claim any credits you are may have access to to — they work together, not against each other.

Common tax credits and who can claim them

The Child Tax Credit gives you up to $2,000 per child under age 17. You must be the child's parent or legal guardian, and the child must have a Social Security number. Income limits explore: the credit begins to shrink if your income exceeds $400,000 (married filing jointly) or $200,000 (single).

The Earned Income Tax Credit (EITC) is for workers with low to moderate income. The amount depends on your income, filing status, and whether you have children. A single person with no children can earn up to roughly $17,000 and still receive a credit; the limit is higher for people with children. The EITC is refundable, so many people receive a refund even if no tax was withheld from their paychecks.

Education credits include the American Opportunity Tax Credit (up to $2,500 per student per year for the first four years of college) and the Lifetime Learning Credit (up to $2,000 per return, not per student). Both require you to pay for tuition, fees, or course materials at an accredited school. Income limits explore to both.

Other credits exist for adoption, energy-efficient home improvements, dependent care expenses, and retirement savings. The IRS website lists all available credits and the forms needed to claim each one.

How to claim a tax credit on your return

You do not receive a tax credit automatically. You must claim it by filing the correct form or schedule with your tax return. For the Child Tax Credit, you report the child's name and Social Security number on Schedule 8812 (or directly on Form 1040 if using the standard form). For the EITC, you use Schedule EIC. Education credits use Form 8863.

If you file electronically through tax software or a tax preparer, the software will ask you questions about your situation and generate the correct forms for you. If you file by hand, you need to obtain the form from the IRS website, fill it out, and attach it to your return. Forgetting to file the form means the IRS will not include the credit, even if you are may have access to to it.

When you file, you will need documentation to back up your claim. For the Child Tax Credit, you need the child's Social Security number. For education credits, you need Form 1098-T from your school showing what you paid. For the EITC, you need proof of income and your children's Social Security numbers if you have dependents. Keep these documents for at least three years in case the IRS asks questions.

Income limits and phase-outs

Most tax credits shrink or disappear as your income rises. This is called a phase-out. The Child Tax Credit, for example, reduces by $50 for every $1,000 (or fraction thereof) that your income exceeds the threshold. If you are married filing jointly and earn $410,000, your credit is $50 less than the full amount. At $420,000, it is $100 less.

The EITC also phases out, but the phase-out range is wider and the reduction is slower. For a single person with no children in 2024, the credit begins to shrink at around $17,000 in income and disappears entirely at around $21,000. For a person with three children, the phase-out begins at a higher income and ends at a higher income.

Education credits have income limits too. If your income exceeds the limit, you cannot claim the credit at all — there is no partial credit. The American Opportunity Tax Credit phases out between $80,000 and $90,000 for single filers (higher for married filers).

When you file your return, the IRS will calculate whether you are subject to a phase-out. If you use tax software, it will do this automatically. If you file by hand, you will need to work through the phase-out calculation on the form itself.

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

If the IRS finds that you claimed a credit incorrectly, they will send you a notice explaining the error and asking you to repay the credit amount plus interest. If the error was unintentional, you usually pay the amount owed and the matter closes. If the IRS believes the error was intentional fraud, you may face penalties on top of the repayment.

The most common mistakes are claiming the Child Tax Credit for a child who does not meet the age or relationship requirements, or claiming the EITC with incorrect income. The IRS cross-checks Social Security numbers and income reported by employers, so discrepancies are often caught during processing or in the years after you file.

If you receive a notice about a credit, read it carefully and respond within the important date given. You can agree with the IRS, disagree and provide documentation to support your claim, or request a hearing if you believe the decision is wrong.

Frequently Asked Questions

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

Yes. You can claim the Child Tax Credit and the EITC in the same year, or the Child Tax Credit and an education credit, or multiple education credits if you have multiple students. The only limit is that you cannot claim two education credits for the same student in the same year — you must choose which one benefits you more.

What if I do not owe any taxes — can I still get a refund from a refundable credit?

Yes, if the credit is refundable. The EITC is refundable, so even if you owe zero tax, you can receive a refund equal to the credit amount. The Child Tax Credit is only partially refundable, so you might receive a partial refund. Non-refundable credits cannot result in a refund if you owe no tax.

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

Yes. Even if you have no tax liability and no income, you must file a return to claim a refundable credit like the EITC. If you do not file, you do not receive the credit or the refund. The IRS does not send credits automatically.

Can my income be too high to claim any tax credits?

Yes. Most credits have income phase-outs or limits. If your income exceeds the limit, you cannot claim that credit. However, different credits have different limits, so you might not be able to claim one credit but can claim another. Check the income limits for each credit you think you might be may have access to to.

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

A tax credit subtracts directly from your tax bill dollar for dollar. A tax deduction reduces your taxable income, so it saves you only a percentage of the deduction amount based on your tax bracket. A $1,000 credit always saves you $1,000. A $1,000 deduction saves you $220 if you are in the 22% bracket, but $370 if you are in the 37% bracket.
