A tax credit is money the government subtracts directly from the taxes you owe

A tax credit reduces your tax bill dollar for dollar. If you owe $2,000 in federal income tax and you have a $500 tax credit, you owe $1,500 instead. This is different from a tax deduction, which only reduces the income the government counts — a deduction saves you money based on your tax rate, but a credit saves you the full amount.

Tax credits come from federal law and sometimes from your state. The IRS administers federal credits. Your state tax agency administers state credits. You claim them on your tax return, either Form 1040 or the forms that go with it, depending on which credit you are using.

Some credits are refundable, meaning if the credit is larger than what you owe, the government sends you the difference as a refund. Other credits are nonrefundable, meaning they can only reduce your tax bill to zero — any leftover credit disappears. A few credits are partially refundable.

Key Takeaways

  • A tax credit subtracts directly from your tax bill, while a deduction only reduces your taxable income.
  • Refundable credits can result in a refund if they exceed what you owe; nonrefundable credits cannot.
  • You claim tax credits on your federal tax return using the forms the IRS publishes for each credit.
  • Common credits include the Earned Income Tax Credit, Child Tax Credit, and education credits like the American Opportunity Credit.

How a tax credit differs from a deduction

The difference matters because a credit saves you more money than a deduction of the same size. Say you earn $50,000 and your tax rate is 12 percent. A $1,000 deduction reduces your taxable income to $49,000, saving you $120 in taxes. A $1,000 credit reduces your tax bill by the full $1,000.

Deductions lower the amount of income you report to the IRS. Credits lower the amount of tax you owe on that income. The IRS publishes a list of deductions — the standard deduction, mortgage interest, charitable donations, and others — and you choose whether to use them. Credits are separate: you claim them only if you meet the rules for that specific credit.

Refundable versus nonrefundable credits

A refundable credit can pay you money even if you do not owe any tax. The Earned Income Tax Credit (EITC) is refundable. If you earn $20,000, owe zero federal tax, and you have a $2,000 EITC, the IRS sends you a $2,000 refund. The credit is "refundable" because the government refunds the part you cannot use to reduce a tax bill.

A nonrefundable credit can only reduce your tax bill to zero. The Child Tax Credit was nonrefundable for many years, though recent law changes made it partially refundable. If you owe $800 in tax and you have a $1,200 nonrefundable credit, the credit wipes out your $800 bill, but you do not get the extra $400. It straightforward disappears.

A partially refundable credit works both ways: part of it can reduce your bill below zero and result in a refund, and part of it cannot. The current Child Tax Credit allows you to get back up to $1,600 as a refund, even if you owe no tax, but the credit itself is $2,000.

Common federal tax credits and who uses them

The Earned Income Tax Credit (EITC) is for working people with low to moderate income. It is refundable. The amount depends on your income, filing status, and number of children. You must have earned income — wages, self-employment income, or similar — to claim it.

The Child Tax Credit is $2,000 per child under age 17. It is partially refundable, meaning you can get back up to $1,600 per child even if you owe no tax. You must be the child's parent or legal guardian and claim them as a dependent on your return.

The American Opportunity Credit is for education expenses. It covers up to $2,500 per student per year for the first four years of college or university. It is partially refundable — up to $1,000 can be refunded to you. You must be paying for a student's tuition, fees, or course materials.

The Lifetime Learning Credit also covers education expenses but works differently: it is nonrefundable, covers up to $2,000 per return (not per student), and has no limit on how many years you can claim it. You choose either this credit or the American Opportunity Credit for each student in a given year, not both.

The Saver's Credit (Retirement Savings Contributions Credit) is for people who save money in a retirement account and have low to moderate income. It is nonrefundable and can be worth up to $1,000.

How to claim a tax credit on your return

You claim a tax credit by filling out the form or schedule that goes with it and attaching it to your Form 1040. The IRS publishes these forms every year. For example, the EITC uses Schedule EIC, the Child Tax Credit uses Schedule 8812, and education credits use Form 8863.

If you use tax software, the software walks you through questions about your situation and fills in the forms for you. If you file by hand, you read the form from IRS.gov, fill it out, and include it with your return when you mail it or file electronically.

You must have the right documents to back up your claim. For the Child Tax Credit, you need the child's Social Security number and proof they lived with you. For education credits, you need the school's name, address, and the amount you paid. For the EITC, you need proof of earned income and your filing status. Keep these documents with your tax records in case the IRS asks questions later.

What happens if you claim a credit you do not meet the rules for

If you claim a credit and the IRS finds out you did not meet the requirements, they will disallow the credit and send you a bill for the taxes you should have paid, plus interest. If the error was unintentional, you may also owe a penalty. If the IRS thinks you did it on purpose, the penalty is larger.

The safest approach is to read the IRS instructions for each credit before you claim it. The instructions list the exact rules — income limits, age requirements, relationship to the person you are claiming for, and what documents you need. If you are unsure whether you meet the rules, you can contact the IRS or speak with a tax professional before you file.

State tax credits

Many states offer their own tax credits on top of federal credits. Some states mirror the federal credits — they offer their own version of the EITC or Child Tax Credit. Other states offer credits for things the federal government does not, such as property tax relief, energy-efficient home improvements, or donations to certain charities.

You claim state credits on your state tax return, not your federal return. Your state tax agency publishes the forms and instructions. If you use tax software, it usually asks about state credits and fills in the state forms for you. If you file by hand, you read the state forms from your state's tax website.

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, for example. You can also claim an education credit and the EITC. However, some credits cannot be claimed together — you cannot claim both the American Opportunity Credit and the Lifetime Learning Credit for the same student in the same year. The IRS instructions for each credit explain which other credits you can combine it with.

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

A tax credit reduces your tax bill directly, dollar for dollar. A tax deduction reduces the amount of income you report, so it saves you money based on your tax rate. A $1,000 credit always saves you $1,000. A $1,000 deduction saves you $120 to $370 depending on your tax rate.

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

Yes. Even if you owe no tax and have no income requirement to file, you must file a return to claim a refundable credit like the EITC. The IRS will not send you the credit money unless you file and claim it on your return.

What if I do not have all the documents the IRS asks for?

Contact the IRS or the organization that issued the document. For a Child Tax Credit, you need the child's Social Security number — if you do not have it, you can request one from the Social Security Administration. For education credits, contact the school for proof of what you paid. The IRS will work with you if you are missing documents, but you must reach out before you file.

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

It depends on the credit. You cannot claim the EITC or the Child Tax Credit if someone else claims you as a dependent. You can claim some education credits even if you are a dependent, but the rules are strict — check the IRS instructions for the specific credit before you file.
