Tax credits and tax deductions can both 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.
At a glance:
- A tax credit reduces the tax you owe dollar for dollar.
- A tax deduction reduces your taxable income; the savings depend on your tax bracket.
- Refundable credits can reduce your tax below zero and create a refund; nonrefundable credits can only reduce your tax to zero.
What is a tax credit?
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.
Tax credits don’t change your taxable income, which is one way they differ from deductions. Because credits reduce tax owed directly, they are often more valuable than deductions of the same dollar amount. Credits generally apply after your income tax is calculated. Refundable credits may also increase your refund when the credit exceeds the tax you owe.
Common tax credits include:
- Child Tax Credit. Up to $2,200 per qualifying child under age 17 (2025 and 2026 tax years)
- Earned Income Tax Credit (EITC). For low- to moderate-income workers
- American Opportunity Tax Credit. For qualified education expenses
- Child and Dependent Care Credit. For childcare and dependent care costs while you work
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. 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 (or partially refundable) credits include:
- EITC. Fully refundable
- Additional Child Tax Credit. A fully refundable portion of the Child Tax Credit, up to $1,700 per qualifying child
- American Opportunity Tax Credit. 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; helps offset the cost of health insurance premiums purchased through the Health Insurance Marketplace
- Fuel Tax Credit. Fully refundable for nontaxable uses of gasoline, aviation gasoline, undyed diesel, and undyed kerosene (mostly for business and farming)
- Adoption Tax Credit. Partially refundable, up to $5,000 per qualifying child for 2025 and $5,120 for 2026
Nonrefundable tax credits
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.
Nonrefundable credits include:
- Child and Dependent Care Tax Credit. For dependents under age 13, a disabled spouse, or a dependent of any age incapable of self-care who lives with you more than half the year
- Lifetime Learning Credit. 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)
- Credit for Other Dependents. $500 per qualifying dependent who does not qualify for the Child Tax Credit
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 x 22%). The same $1,000 in tax credits would save you $1,000.
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 status | Standard deduction amount |
|---|---|
| Single/Married Filing Separately | $15,750 |
| Married Filing Jointly | $31,500 |
| Head of Household | $23,625 |
For 2026, those amounts increase to:
| Filing status | Standard deduction amount |
|---|---|
| Single/Married Filing Separately | $16,100 |
| Married Filing Jointly | $32,200 |
| Head of Household | $24,150 |
Itemized deductions
Itemized deductions are specific expenses the IRS allows you to deduct individually instead of taking the standard deduction. You list these on Schedule A. Common itemized deductions include:
- State and local taxes (SALT), 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.
- 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
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.
Above-the-line deductions
Above-the-line deductions, also called adjustments to income, reduce your AGI. You claim them on Schedule 1 before you choose the standard deduction or itemize, so they’re available either way. Because they lower AGI, they 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)
Tax credit vs. tax deduction: the difference
| Tax deduction | Tax credit | |
|---|---|---|
| What it reduces | Taxable income | Tax owed |
| Value depends on | Deduction amount and your marginal tax rate | Credit amount, eligibility rules, and whether the credit is refundable |
| $1,000 benefit (22% bracket) | About $220 tax savings | Up to $1,000 tax savings |
| Can create a refund beyond zero liability | No | Yes, 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. Each break has its own eligibility rules, so it pays to review everything you might qualify for.
