Tax Credits vs. Tax Deductions: What's the Difference?

Tax credits and tax deductions can both help lower your tax bill, but they don’t work the same way. A tax deduction reduces your taxable income, while a tax credit reduces the amount of tax you owe dollar for dollar.

So, which one is better: a tax credit or a tax deduction? The answer depends on the tax break and your situation. In this guide, we’ll explain the difference between tax credits and tax deductions, how refundable and nonrefundable credits work, and how to use both to potentially save money at tax time.

What is a tax credit?

If you’ve been looking for ways to lower your tax bill, you’ve likely heard of tax credits. A tax credit is a dollar-for-dollar reduction of the tax you owe. For example, if you qualify for a $1,000 tax credit and owe $3,000 in federal income tax, your tax bill drops to $2,000.

It’s important to note that tax credits don’t change your taxable income, which is one of the ways they differ from deductions. Because credits reduce tax owed directly, they are often more valuable than deductions of the same dollar amount. Tax credits generally apply after your income tax is calculated, directly reducing your tax liability. Refundable credits may also increase your refund when the credit exceeds the tax you owe.

Common tax credits to look out for include:

Refundable tax credits

Now that we’ve covered the basics of tax credits, let’s explore refundable tax credits. A refundable tax credit can reduce your tax liability below zero. If the credit exceeds what you owe, you receive the difference as a refund.

Here’s a straightforward example:

You owe $800 in federal income tax and qualify for a $2,000 refundable credit. After the credit is applied, you owe $0 and receive a $1,200 refund from the excess credit.

Refundable credits are especially helpful for taxpayers who owe little or no tax but still qualify based on income, family size, or other factors. The Earned Income Tax Credit is fully refundable. The Child Tax Credit is partially refundable (up to $1,700 per qualifying child through the Additional Child Tax Credit) if you meet earned income requirements.

Refundable tax credits include:

EITC. Fully refundable

Additional Child Tax Credit. A fully refundable portion of the CTC, up to $1,700 per qualifying child

AOTC. Partially refundable for the first four years of higher education (up to 40% of the credit, or $1,000, may be refundable)

Premium Tax Credit. Refundable to help eligible individuals and families offset the cost of premiums for health insurance purchased through the Health Insurance Marketplace

Fuel Tax Credit. Fully refundable for nontaxable uses of gasoline, aviation gasoline, undyed diesel, and undyed kerosene (mostly applicable to business and farming)

Adoption Tax Credit. Partially refundable, with a limit up to $5,000 per qualifying child for 2025 and $5,120 for 2026

Nonrefundable tax credits

Unlike a refundable credit, a nonrefundable tax credit can only reduce your tax bill to zero. It can’t create a refund beyond that point.

Example: You owe $500 in federal income tax and qualify for a $1,200 nonrefundable credit. Your tax bill goes to $0, but you do not receive the remaining $700 as a refund.

Some education credits and the Credit for Other Dependents ($500 per qualifying dependent who does not qualify for the Child Tax Credit) work this way. Nonrefundable credits are still valuable as they can wipe out a tax bill entirely, but they won’t put extra cash in your pocket once your liability hits zero.

Nonrefundable tax credits include:

Child and Dependent Care Tax Credit. Applicable for dependents under the age of 13, a disabled spouse, or a dependent of any age who is incapable of self-care and who lives with you for more than half of the year.

Lifetime Learning Credit. Allows a credit of up to $2,000 per tax return

Energy Efficient Home Improvement Credit. Up to 30% of certain qualified expenses in the year of installation (Credit ends for property placed in service after Dec. 31, 2025)

What is a tax deduction?

A tax deduction reduces your taxable income, not your tax bill directly. Less taxable income generally means a lower tax bill, but the savings depend on your tax bracket.

Example: You are in the 22% tax bracket and claim a $1,000 deduction. That deduction saves you about $220 in taxes ($1,000 × 22%). The same $1,000 in tax credits would save you $1,000.

Deductions come in several forms. Most taxpayers use one of the following:

Standard deduction

The standard deduction is a fixed amount you can subtract from your income without listing individual expenses. Most taxpayers take it because it is simple and often provides a larger benefit than itemizing.

For 2025, the standard deduction amounts are:

Filing statusStandard deduction amountSingle/Married Filing Separately$15,750Married Filing Jointly$31,500Head of Household$23,625

For 2026, those amounts increase to:

Filing statusStandard deduction amountSingle/Married Filing Separately$16,100Married Filing Jointly$32,200Head of Household$24,150

You generally don’t need to document individual expenses to claim the standard deduction. Its amount is based primarily on your filing status, although different rules may apply based on age, blindness, dependent status, and certain other circumstances.

Itemized deductions

Itemized deductions are specific expenses that the IRS allows you to deduct individually instead of taking the standard deduction. You should list these on Schedule A.

Some common itemized deductions include:

State and local taxes (SALT), subject to the SALT deduction limit

Mortgage interest on a qualified home loan

Charitable contributions

Qualified unreimbursed medical and dental expenses that exceed 7.5% of AGI

Casualty and theft losses in federally declared disaster areas

So, when does itemizing make sense? Itemizing makes sense when your total itemized deductions exceed your standard deduction. For example, if your itemized total is $18,000 and your standard deduction is $15,750, itemizing saves you tax on that extra $2,250 of deductions.

Note: State and local taxes, subject to the SALT deduction limit. For 2025, the limit is generally $40,000, or $20,000 if married filing separately, with a reduction for taxpayers above certain income levels.

Above-the-line deductions

Above-the-line deductions, which are also called adjustments to income, reduce your AGI. You claim above-the-line deductions on Schedule 1 before you choose the standard deduction or itemize.

Because they lower AGI, above-the-line deductions can help you qualify for other tax breaks that phase out at higher income levels.

Examples include:

Deductible traditional IRA contributions (subject to income limits and workplace retirement-plan rules)

Student loan interest deduction (up to $2,500, subject to income limits)

Self-employment tax deduction (half of what you pay)

Certain health savings account (HSA) contributions

Educator expenses (up to $350 for eligible teachers)

Above-the-line deductions are available whether you take the standard deduction or itemize, so you don’t need to choose between the two.

Tax credit vs. tax deduction: What is the difference between tax credits and tax deductions?

Now for the most important question: what’s the difference between tax credits and tax deductions? To start, here’s a simple way to differentiate them:

Tax deductionTax creditWhat it reducesTaxable incomeTax owedValue depends onDeduction amount and your marginal tax rateCredit amount, eligibility rules, and whether the credit is refundable$1,000 benefit (22% bracket)About $220 tax savingsUp to $1,000 tax savingsCan create a refund beyond zero liabilityNoYes, if the credit is refundable

The key difference is what each tax break reduces. Deductions reduce the amount of income subject to tax, while credits reduce the tax calculated on that income.

In many cases, you can claim both on the same return. For example, you might take the standard deduction and claim the Child Tax Credit. Or you might itemize mortgage interest and claim education credits. Each break has its own eligibility rules, so it pays to review everything you might qualify for.

How to maximize your tax refund

Getting closer to owing $0, or receiving a refund, usually comes down to three things: lowering taxable income, claiming every credit you qualify for, and adjusting withholding so you’re not over- or under-paying during the year. These five steps may help:

1. Claim all eligible deductions.Compare the standard deduction against itemizing. Track charitable gifts, medical expenses, and other costs throughout the year so you have the numbers when it is time to file.

2. Don’t overlook above-the-line deductions.Contributions to a traditional IRA or HSA, student loan interest, and self-employment adjustments can lower AGI even if you take the standard deduction.

3. Review tax credits carefully.Credits often have income limits, age requirements, or documentation rules. Missing a credit that you qualify for can cost far more than missing a small deduction.

4. Check your withholding.If your refund is consistently much larger than expected, review your withholding. You may have had more tax withheld than necessary, although refundable credits can also contribute to a large refund.

5. Use tax software that asks the right questions.Tax software, such as TaxAct®, walks you through an interview-style filing experience and helps identify deductions and credits based on your answers. This method reduces the chances of leaving money on the table.

FAQs

What is a tax credit vs. deduction?

A tax credit reduces the tax you owe dollar-for-dollar. A tax deduction reduces your taxable income, which indirectly lowers your tax bill based on your tax bracket.

After your tax liability is calculated, eligible credits are subtracted from that amount. Refundable credits can reduce your bill below zero, resulting in a refund. Nonrefundable credits can only bring your liability to zero.

Tax credits are tax benefits authorized under federal law that directly reduce income tax liability when the applicable eligibility requirements are met. They reward specific situations, such as raising children, paying for college, or earning modest wages, and are claimed on your federal (and sometimes state) return when you meet the requirements.

Tax deductions are expenses or fixed amounts that the IRS lets you subtract from your income. They include the standard deduction, itemized deductions such as mortgage interest and charitable contributions, and above-the-line adjustments, such as IRA contributions.

What does tax-deductible mean?

When an expense is tax-deductible, federal tax law allows it to reduce the income on which tax is calculated, provided the applicable requirements are met. Depending on the expense, it may be claimed as an adjustment to income, an itemized deduction, or a deduction associated with business or investment activity.

Is the child tax credit refundable?

Partially. For 2025 and 2026, the Child Tax Credit is worth up to $2,200 per qualifying child, and up to $1,700 per child may be refundable through the Additional Child Tax Credit. The ACTC is generally calculated as 15% of earned income over $2,500, subject to the per-child limit and other eligibility and calculation rules.

The bottom line

Understanding the distinction between tax credits and tax deductions can make a real difference when it comes to lowering your tax bill. Deductions help reduce your taxable income, and credits cut down what you owe dollar for dollar, so they’re definitely worth paying attention to. By understanding when and how to use both, you can help ensure you’re not leaving money on the table.
