What Is the Difference Between a Tax Credit and a Tax Deduction for Expats?
A tax credit reduces the amount of tax you owe dollar-for-dollar, while a tax deduction reduces the income on which your tax is calculated. A $1,000 tax credit saves you $1,000 in tax regardless of your bracket. A $1,000 tax deduction saves you $1,000 times your marginal tax rate, so $220 if you are in the 22% bracket (IRS: Credits and Deductions for Individuals).
| Feature | Tax Credit | Tax Deduction |
| Reduces | Tax owed directly | Taxable income |
| $1,000 at 22% bracket | Saves $1,000 | Saves $220 |
| $1,000 at 37% bracket | Saves $1,000 | Saves $370 |
| More valuable at | Any bracket (always dollar-for-dollar) | Higher brackets |
| Refundable? | Some credits are (e.g., Additional CTC) | Never |
Common credits for expats:
- Foreign Tax Credit (Form 1116): offsets U.S. tax dollar-for-dollar for foreign income taxes paid; the most important credit for most expats
- Child Tax Credit: $2,000 per child under 17 (2025); partially refundable
- Education credits: American Opportunity and Lifetime Learning credits for U.S. institution tuition
Common deductions for expats:
- Foreign Earned Income Exclusion: technically an exclusion (removes income entirely), not a deduction, but has a similar effect
- Standard deduction: $15,750 single, $31,500 MFJ (2025)
- Self-employment tax deduction: 50% of SE tax is deductible above the line
When the distinction matters for expats:
- FTC vs itemized deduction for foreign taxes: You can claim foreign taxes paid as either a credit (Form 1116) or an itemized deduction (Schedule A), but almost never as both. The credit is nearly always better because it is dollar-for-dollar.
- FEIE is an exclusion, not a credit or deduction: it removes income from the calculation entirely, which is different from both
