Foreign Tax Credits: How They Work and Their Limits
1 / 7
What is the foreign tax credit?
- It is a dollar-for-dollar reduction of U.S. income tax for income taxes paid or accrued to a foreign country or U.S. possession.
- Its purpose is to reduce double taxation of income taxed both abroad and by the U.S.
- Individuals can take a credit or, alternatively, an itemized deduction for foreign taxes, but not both in the same year.
- Most individuals claim it on Form 1116, with a simplified election for small amounts.

What is the foreign tax credit?
- It is a dollar-for-dollar reduction of U.S. income tax for income taxes paid or accrued to a foreign country or U.S. possession.
- Its purpose is to reduce double taxation of income taxed both abroad and by the U.S.
- Individuals can take a credit or, alternatively, an itemized deduction for foreign taxes, but not both in the same year.
- Most individuals claim it on Form 1116, with a simplified election for small amounts.
Which foreign taxes qualify?
- Only foreign income taxes, and taxes imposed in place of an income tax, qualify.
- Value-added, sales, property, and most excise taxes do not qualify.
- Tax that could be refunded, such as excess withholding reducible under a treaty, is not creditable.
- Taxes on income excluded under the foreign earned income exclusion cannot be credited.
How is the credit limited?
- The credit cannot exceed the U.S. tax attributable to foreign-source taxable income.
- The limit is roughly U.S. tax multiplied by foreign-source taxable income divided by worldwide taxable income.
- How deductions are allocated between U.S. and foreign income changes the limit.
- The limit is figured separately for each income category, such as passive and general.
What are the income categories?
- Passive category income generally includes dividends, interest, rents, royalties, and gains from investments.
- General category income generally includes wages and active business income earned abroad.
- Excess credits in one category cannot offset U.S. tax on income in another category.
- Certain other categories apply to specific situations, such as treaty-resourced income.
What happens to unused credits?
- Foreign taxes above the limit can be carried back one year and then forward up to ten years.
- Carryovers stay within the same income category.
- Unused credits expire when the carryforward period ends.
- Timing of income recognition can affect whether carryovers get used.
Can small amounts be claimed without Form 1116?
- Yes, if all foreign income is passive, reported on qualified payee statements such as a 1099-DIV, and total creditable taxes are $300 or less ($600 joint).
- This commonly applies to foreign tax passed through by international mutual funds and ETFs.
- Using the election means no carryback or carryforward of excess credit for that year.
- Treaty-based return positions that change U.S. tax may need disclosure on Form 8833.
Key takeaways
- The credit offsets U.S. tax with foreign income taxes, limited to U.S. tax on foreign-source income.
- Limits apply by income category, with a one-year carryback and ten-year carryforward.
- The same income cannot be both excluded under the FEIE and used for a credit.
- Form 1116 is technical; confirm with a CPA experienced in international tax.
