A tax credit reduces the amount of tax you owe, dollar for dollar

A 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 $500 tax credit, you owe $1,500 instead. That is different from a tax deduction, which reduces the income the government counts — a deduction saves you money only on the portion you would have paid in tax, but a credit saves you the full amount.

Tax credits exist because the government wants to encourage certain behaviors or help certain groups of people. The Earned Income Tax Credit (EITC) rewards people who work but earn modest wages. The Child Tax Credit puts money back in the pockets of parents. Other credits cover education costs, energy-efficient home improvements, or adoption expenses. The IRS publishes the full list each year in Publication 17.

Some credits are refundable, meaning if the credit is larger than the tax you owe, the government sends you the difference as a refund. Others are nonrefundable, meaning they can reduce your tax bill to zero but no further. A few credits are partially refundable. This distinction matters: a refundable credit can put money in your pocket even if you paid no tax at all.

Key Takeaways

  • A tax credit subtracts directly from the tax you owe, while a deduction reduces the income that gets taxed.
  • Refundable credits can result in a refund if they exceed what you owe; nonrefundable credits can only reduce your bill to zero.
  • Common credits include the Earned Income Tax Credit (EITC) for working people with lower incomes, the Child Tax Credit for parents, and education credits for students and their families.
  • You claim tax credits on your federal tax return using specific IRS forms and schedules that match each credit type.

Refundable vs. nonrefundable credits

The difference between refundable and nonrefundable credits determines whether you walk away with money or straightforward owe less. A refundable credit works like this: suppose you owe $800 in tax but you have a $1,200 refundable credit. The credit wipes out the $800 you owe and leaves $400 extra, which the IRS sends to you as a refund check. The Earned Income Tax Credit is refundable, as is the Additional Child Tax Credit (a refundable portion of the main Child Tax Credit).

A nonrefundable credit stops at zero. If you owe $800 and have a $1,200 nonrefundable credit, the credit eliminates the $800 you owe, but you do not receive the extra $400. The American Opportunity Tax Credit (for education) is nonrefundable, though up to $1,600 of it can be refundable under certain rules. The Lifetime Learning Credit is nonrefundable.

Some credits are partially refundable, meaning a portion of the credit can result in a refund and the rest cannot. The Child Tax Credit is an example: up to $1,700 of it (for tax year 2023) can be refundable as the Additional Child Tax Credit, but the rest is nonrefundable. The IRS instructions for each credit spell out which portion is refundable.

Common tax credits and who they are for

The Earned Income Tax Credit (EITC) is the largest refundable credit for working people with lower to moderate incomes. You must have earned income from a job or self-employment, and your income must fall below a threshold that changes each year. The credit amount depends on your income, filing status, and whether you have children. For tax year 2023, the maximum credit was $3,995 for people with three or more children.

The Child Tax Credit provides up to $2,000 per child under age 17 for each may have access to child. You must claim the child as a dependent, and the child must be a U.S. citizen, national, or resident alien. The credit phases out at higher income levels. Part of this credit is refundable (the Additional Child Tax Credit), which means some families receive a refund even if they owe no tax.

Education-related 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 for any education beyond high school). You cannot claim both credits for the same student in the same year. These credits cover tuition, fees, and course materials, but not room and board.

Other credits cover specific situations: the Adoption Credit reimburses adoption expenses, the Saver's Credit rewards people who save for retirement, and the Residential Energy Credits cover solar panels, heat pumps, and other home improvements. The IRS website lists all available credits and the income limits for each.

How to claim a tax credit on your return

You claim a tax credit by filling out the correct form or schedule and attaching it to your federal tax return. Each credit has its own form. The EITC uses Schedule EIC. The Child Tax Credit goes on Schedule 8812. Education credits use Form 8863. If you use tax software, the program typically walks you through questions about your situation and fills in the correct forms automatically.

To claim a credit, you must meet all the requirements for that specific credit. The IRS publishes detailed instructions for each form, available free on IRS.gov. If you file by paper, you print the form, fill it out, and mail it with your return. If you file electronically, the software submits the form as part of your return file.

Keep records of anything the credit requires: receipts for education expenses, proof of adoption costs, documentation of home improvements, or pay stubs showing earned income. The IRS does not always ask for these documents when you file, but you must have them if the agency audits your return.

Income limits and phase-outs

Most tax credits have income limits. If your income is too high, 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, for example, reaches its maximum at a certain income level, stays flat for a range of incomes, then decreases as income rises further.

The income threshold and phase-out rate vary by filing status and family size. For the EITC, a single person with no children has a lower income limit than a married couple with three children. The IRS publishes income limits each year in the instructions for each form. Tax software automatically calculates whether you exceed the limit and reduces your credit accordingly.

If your income is close to the limit, it may be worth timing when you receive income or claim deductions. For example, if you are self-employed and close to the EITC income limit, deferring some income to the next year might allow you to claim the credit. A tax professional can help you understand how income timing affects your credits.

Tax credits vs. tax deductions

The difference between a credit and a deduction is straightforward but important. A tax deduction reduces the income the government counts as taxable. If you earn $50,000 and claim a $5,000 deduction, the government taxes you on $45,000 instead. The tax savings depend on your tax rate — if you are in the 22% bracket, a $5,000 deduction saves you $1,100.

A tax credit subtracts directly from your tax bill. A $5,000 credit saves you $5,000 no matter what tax bracket you are in. For this reason, credits are almost always more valuable than deductions of the same dollar amount. If you have a choice between a credit and a deduction, the credit is usually better.

Some people can claim both. You might deduct mortgage interest (a deduction) and also claim the Child Tax Credit (a credit) in the same year. The IRS rules determine which deductions and credits you can combine, and tax software handles the calculation.

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

If you claim a tax credit and the IRS later determines you did not meet the requirements, the agency will disallow the credit and send you a bill for the tax you should have paid, plus interest. If the error was unintentional, you may avoid penalties, but you will still owe the tax and interest. If the IRS suspects fraud, penalties can be steep.

The most common mistakes are claiming the EITC with income above the limit, claiming the Child Tax Credit for a child who does not meet the age or relationship requirements, or claiming education credits without proper documentation. The IRS matches information from employers, schools, and financial institutions against your return, so discrepancies often get caught.

If you are unsure whether you may have access to for a credit, it is safer to leave it off your return or to consult a tax professional. The IRS provides free tax help through Volunteer Income Tax information (VITA) sites in many communities, and these volunteers can review your situation before you file.

Frequently Asked Questions

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

Yes. You can claim multiple credits in the same year if you meet the requirements for each one. For example, you might claim the Child Tax Credit, the EITC, and an education credit all on the same return. Tax software will calculate all credits you are may have access to to and explore them in the order that benefits you most.

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

A tax credit is a reduction in the tax you owe. A tax refund is money the government sends you because you overpaid your tax during the year (through withholding or estimated payments) or because you claimed a refundable credit. A refundable credit can create a refund even if you did not overpay.

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

Yes, you must file a federal tax return to claim a tax credit. Even if you have no tax liability, you may need to file to claim a refundable credit like the EITC. The IRS website has a tool to help you determine whether you must file.

What if my income changes during the year and I end up over the credit limit?

You claim the credit based on your actual income for the full year. If your income rises above the limit after you file, you cannot claim the credit. If you claimed it and your income later exceeds the limit, the IRS will disallow it and bill you for the difference. Some people estimate their income conservatively to avoid this problem.

Can I claim a tax credit if I am claimed as a dependent on someone else's return?

It depends on the credit. Some credits (like the Child Tax Credit) go to the person who claims you as a dependent. Others (like the EITC) require you to file your own return and cannot be claimed if someone else claims you as a dependent. Check the rules for the specific credit you are interested in.
