How Do Tax Credits Work?

Short answer

A tax credit directly reduces the federal income tax you owe. For example, a $1,000 credit lowers your tax bill by $1,000. Some credits can also increase your refund. The result depends on whether the credit is refundable, nonrefundable, or partially refundable.

Tax credits vs. tax deductions

A tax credit reduces your tax liability, while a tax deduction reduces the taxable income used to calculate your tax.

A credit is worth the same amount no matter your tax bracket. For example, a $1,000 credit lowers your tax by $1,000 whether you’re in the 12% bracket or the 37% bracket.

On the other hand, deductions depend on your marginal tax rate, so an equal-sized deduction usually saves you less. Keep in mind the amount you can claim still depends on your income, since many credits and deductions phase out above certain income (AGI) thresholds.

For deductions, you can either claim the standard deduction or itemized deductions. Typically, filers claim the standard deduction unless total itemized deductions exceed the standard deduction amount for their filing status.

Types of tax credits

The type of credit (refundable, nonrefundable, or partially refundable) determines what happens if the credit is greater than your tax bill.

Eligibility requirements

The requirements for each credit vary, but typically, eligibility depends on factors such as your:

  • Income
  • Filing status
  • Dependents
  • Expenses

Common tax credits

Common credits include:

  • Child Tax Credit (CTC): Up to $2,200 per qualifying child, and partially refundable through the Additional Child Tax Credit (ACTC), which can be as much as $1,700 per child.
  • Earned Income Tax Credit (EITC): A refundable credit for low-to-moderate-income workers and families; the amount varies by income, family size, and filing status, but the maximum for 2026 is $8,231.
  • Education credits: The American Opportunity Tax Credit (AOTC) is worth up to $2,500 per student and is 40% refundable (up to $1,000), while the Lifetime Learning Credit (LLC) is worth up to $2,000 per return and is nonrefundable.
  • Child and Dependent Care Credit (CDCC): Helps offset the cost of care for a qualifying child or dependent while you worked or looked for work. The credit is a percentage (20% to 50%) of your care expenses — up to $1,500 for one person or $3,000 for two or more for 2026.
  • Premium Tax Credit (PTC): A refundable credit that helps pay for health coverage bought through the Health Insurance Marketplace.

Keep in mind, some credit amounts are adjusted annually for inflation.

How to claim a tax credit on your tax return

You claim credits when filing Form 1040 and required schedules or forms for specific credits. To claim credits on your return, you’ll need to:

  1. Confirm the eligibility rules.
  2. Gather records such as Social Security numbers, tuition statements, or child care receipts.
  3. Complete Form 1040 yourself, or use tax software or a tax professional to help you calculate your available credit, apply income limits, and complete your tax return.
