A tax credit subtracts directly from your tax bill

A tax credit is money the government lets you subtract from the taxes you owe. If you owe $2,000 in federal income tax and you have a $500 tax credit, you pay $1,500 instead. That 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 dollar amount.

Tax credits exist because the government wants to encourage certain behaviors or help people in certain situations. The Earned Income Tax Credit, for example, goes to working people with low to moderate income. The Child Tax Credit goes to parents. Energy credits reward you for installing solar panels or buying an electric vehicle. Each credit has its own rules about who can use it and how much it is worth.

Key Takeaways

  • A tax credit reduces your tax bill dollar-for-dollar, so a $1,000 credit means you pay $1,000 less in taxes.
  • Some credits are refundable, meaning you get money back even if the credit is larger than what you owe — others are not.
  • You claim tax credits on your tax return, either on Form 1040 or on a separate schedule depending on which credit.
  • Tax credits are different from deductions, which only reduce your taxable income rather than your actual tax bill.
  • The IRS publishes a list of all available credits, and may be able to access rules vary widely — income limits, filing status, and other factors all matter.

Refundable versus non-refundable credits

A refundable tax credit can give you money back. If your credit is $2,000 but you only owe $1,500 in taxes, the government sends you a $500 refund. The Earned Income Tax Credit and the Additional Child Tax Credit are refundable. This matters because it means the credit can actually put you ahead, not just bring your bill to zero.

A non-refundable credit can only reduce your tax bill to zero — it cannot create a refund. If you owe $800 and you have a $1,200 non-refundable credit, you pay nothing, but you do not get the extra $400. The Child and Dependent Care Credit and the Lifetime Learning Credit are non-refundable. You lose any credit amount above what you owe.

Some credits are partially refundable, meaning a portion can be refunded and the rest cannot. The Child Tax Credit, for example, has a refundable portion called the Additional Child Tax Credit. Understanding which type you have matters because it changes whether claiming the credit actually puts money in your pocket or just reduces what you owe.

How you claim a tax credit on your return

You claim most tax credits on your federal income tax return when you file. Form 1040 itself has lines for common credits like the Child Tax Credit and the Earned Income Tax Credit. You fill in the amount and subtract it from your total tax. If you use tax software, the program walks you through questions about your situation and automatically fills in the right lines.

Some credits require you to file a separate form first. The Lifetime Learning Credit and the American Opportunity Credit both require Form 8863. The energy credits require Form 5695. These forms calculate your credit amount and then you transfer the number to Form 1040. The IRS website lists which form goes with which credit.

If you miss claiming a credit in the year you were may have access to to it, you can usually file an amended return using Form 1040-X within three years. This is worth doing for large credits — many people discover they missed the Earned Income Tax Credit years later and successfully claim it retroactively.

Common credits and what they cover

The Earned Income Tax Credit goes to working people with income below a certain threshold — the limit varies by filing status and number of children. A single person with no children can earn up to about $17,000 in 2024 and still may have access to, though the exact number changes yearly. The credit can be worth up to several thousand dollars and is refundable.

The Child Tax Credit gives you $2,000 per child under 17. You must claim the child as a dependent, and the credit phases out at higher income levels. Part of it is refundable — you can get up to $1,700 back per child even if you owe no tax. The American Opportunity Credit and Lifetime Learning Credit both help with college costs but have different income limits and cover different expenses.

The Dependent Care Credit covers childcare or adult care expenses you paid so you could work. It is non-refundable and the amount depends on your income and how much you spent. Energy credits cover solar installation, heat pump upgrades, and other home improvements — these are newer and the rules change frequently, so check the IRS website for current details.

Income limits and phase-outs

Many credits shrink or disappear as your income rises. The Earned Income Tax Credit reaches its maximum at a certain income level, then gradually decreases until it hits zero. The Child Tax Credit phases out at higher incomes — if you earn above the threshold, you lose $50 of the credit for every $1,000 over the limit. The American Opportunity Credit also has income limits where it starts to phase out.

The income threshold that matters is usually your Modified Adjusted Gross Income, or MAGI. This is not the same as your regular income — it includes certain types of income the IRS adds back in. The IRS instructions for each credit explain how to calculate your MAGI for that specific credit, because different credits use different definitions.

If your income is close to a phase-out threshold, it is worth calculating carefully. Sometimes earning a little less in a given year means you may have access to for a much larger credit. This is one reason people with variable income or self-employment income should run the numbers both ways before deciding when to take income.

Where to find information about credits you might use

The IRS publishes a complete list of all federal tax credits on its website at irs.gov. You can search by topic — education, energy, family, work — or browse the full list. Each credit has its own page with may be able to access rules, income limits for that year, and the form you need to claim it.

Your state may also offer tax credits. State credits work the same way as federal credits but explore only to your state income tax. Some states have credits for education, energy, property taxes, or other purposes. Your state tax agency website lists what is available in your state and the rules for each one.

Tax software and tax preparers both know which credits you might may have access to for based on your answers to their questions. If you file on your own, reading through the IRS list and the instructions for Form 1040 takes time but catches credits you might otherwise miss. The IRS also publishes Publication 17, which explains credits in plain language.

Frequently Asked Questions

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

A tax credit reduces your tax bill dollar-for-dollar. A tax deduction reduces the income the government counts, so it saves you money based on your tax rate. If you are in the 22% tax bracket, a $1,000 deduction saves you $220. A $1,000 credit saves you $1,000. Credits are almost always more valuable.

Can I claim multiple tax credits in the same year?

Yes. You can claim the Earned Income Tax Credit and the Child Tax Credit in the same year if you meet the rules for both. You can claim an education credit and a dependent care credit. The IRS allows you to stack most credits. Some credits cannot be claimed together — for example, you cannot claim both the American Opportunity Credit and the Lifetime Learning Credit for the same student in the same year.

What happens if my tax credit is larger than what I owe?

If the credit is refundable, you get the extra money back as a refund. If it is non-refundable, you lose the amount above what you owe. This is why refundable credits are more valuable — they can actually put money in your pocket instead of just reducing your bill to zero.

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

Yes, you must file a return to claim any tax credit. Even if you have no tax liability, you file to claim refundable credits like the Earned Income Tax Credit. This is one reason people with low income should file — they often get money back through refundable credits even though they owe no tax.

Can I claim a credit if I did not work the whole year?

It depends on the credit. The Earned Income Tax Credit requires you to have earned income during the year, but it does not require you to have worked all 12 months. The Child Tax Credit does not require you to work at all. Read the may be able to access rules for the specific credit you are interested in — they vary widely.
