The Foreign Tax Credit: How to Avoid Double Taxation
The foreign tax credit is a dollar-for-dollar reduction of your U.S. income tax for income taxes you paid to a foreign country, and it exists to stop the same income from being taxed twice. If you earned wages, interest, dividends, or business income abroad and a foreign government taxed it, you may credit that foreign tax against your U.S. bill, usually by filing Form 1116 with your Form 1040. The credit is capped so it never exceeds the U.S. tax on your foreign-source income.
What the foreign tax credit does
The foreign tax credit (FTC) offsets U.S. income tax with income taxes you paid or accrued to a foreign country or U.S. possession. Because the United States taxes citizens and residents on worldwide income, the same dollar can be taxed abroad and at home. The credit removes that overlap by subtracting foreign income tax directly from U.S. tax owed.
A credit reduces tax owed dollar for dollar, unlike a deduction that only reduces taxable income. If you paid $2,000 in foreign income tax, an FTC can cut your U.S. tax by up to $2,000, subject to the limitation described below.
The credit applies only to income taxes (or taxes paid in lieu of an income tax). Foreign value-added tax, sales tax, property tax, and social security taxes generally do not qualify. The credit is separate from foreign reporting duties like FATCA reporting on Form 8938 and the FBAR (FinCEN Form 114), which disclose foreign assets and accounts rather than claim a credit.
Which foreign taxes qualify
A foreign tax qualifies for the credit only if it meets four tests set out by the IRS. Miss any one and the tax is not creditable, though it may still be deductible.
The four requirements:
- The tax must be imposed on you.
- You must have paid or accrued the tax.
- The tax must be a legal and actual foreign tax liability (not refundable or subsidized back to you).
- The tax must be an income tax, or a tax paid in lieu of an income tax.
Taxes that generally do not qualify include foreign VAT, sales tax, real property tax, and amounts you can recover through a refund or treaty. Foreign social security taxes are usually excluded, though a totalization agreement can change how those are handled depending on the country.
Credit vs. deduction: which to choose
You choose each year between claiming a foreign tax credit or deducting foreign taxes as an itemized deduction on Schedule A. That choice ties into the broader standard vs itemized deduction decision on your return. You cannot split the same taxes between both. The credit is usually worth more because it cuts tax directly, while a deduction only reduces the income that gets taxed.
| Feature | Foreign tax credit | Itemized deduction |
|---|---|---|
| Where claimed | Form 1116 (or direct, under the $300/$600 rule) | Schedule A (Form 1040) |
| Tax benefit | Dollar-for-dollar reduction of U.S. tax | Reduces taxable income only |
| Requires itemizing | No | Yes |
| Unused amount | Can carry back 1 year, forward 10 | Lost in the current year |
| Typical result | Larger benefit in most cases | Rarely better |
A deduction can occasionally win, for example if foreign taxes are small and you already itemize heavily, or if credit limitation rules would strand most of the credit. In many cases, though, the credit produces the lower total tax.
Form 1116: how you claim the credit
Form 1116, Foreign Tax Credit, is the form individuals, estates, and trusts use to compute and claim the FTC, and you attach it to your Form 1040 individual income tax return, Form 1040-SR, or Form 1040-NR. It reports your foreign-source income, the foreign taxes paid or accrued, and applies the limitation that caps the credit.
You generally file a separate Form 1116 for each category of income (see baskets below), because the limitation is computed per category. The form walks through your gross foreign income, allocable deductions, foreign taxes, and the resulting credit.
Corporations use Form 1118 instead. The $300/$600 shortcut described next is only available to individuals, not to estates or trusts.
The $300/$600 rule: claiming the credit without Form 1116
You can skip Form 1116 and claim the credit directly on Schedule 3 if your total creditable foreign taxes are $300 or less ($600 or less on a joint return), and specific conditions are met. This is an election that trades simplicity for the loss of carryovers.
To qualify for the no-1116 election, all of the following must be true:
- All of your foreign-source income is passive category income (typically interest and dividends).
- That income and the related foreign tax are reported to you on a qualified payee statement, such as Form 1099-DIV, 1099-INT, or a Schedule K-1.
- Your total creditable foreign taxes for the year are $300 or less, or $600 or less if married filing jointly.
The trade-off: when you make this election, the credit limitation calculation does not apply, but you also cannot carry any excess foreign tax back or forward. Estates and trusts cannot use this shortcut and must file Form 1116.
The credit limitation and income baskets
The foreign tax credit cannot exceed the portion of your U.S. tax that applies to your foreign-source income. This limitation stops the credit from wiping out U.S. tax on U.S.-source income. It is computed separately for each category of income, called a basket, so high tax in one basket cannot offset U.S. tax in another.
The limitation formula, applied per basket:
FTC limit = U.S. tax before credits x (foreign-source taxable income in the basket / total taxable income)
The credit for that basket is the smaller of the foreign tax paid in the basket or this limit. If your foreign tax rate is higher than your U.S. rate on the same income, some credit will exceed the limit and become an excess credit you may carry to another year.
The income categories (baskets) on Form 1116:
| Basket | What it covers |
|---|---|
| Passive category | Dividends, interest, royalties, rents, most capital gains |
| General category | Wages, active business income, most earned income |
| Section 951A (GILTI) | Global intangible low-taxed income from controlled foreign corporations reported on Form 5471 |
| Foreign branch | Business profits of a foreign qualified business unit |
| Section 901(j) | Income from sanctioned countries (credit disallowed, tracked separately) |
| Treaty re-sourced | U.S.-source income re-sourced to foreign under a treaty |
| Lump-sum distributions | Certain qualified pension distributions |
Most individual filers deal only with the passive and general baskets.
Carryback and carryover of unused credits
When your foreign tax exceeds the limitation for a basket, the unused amount does not disappear. You can carry the excess credit back 1 year and forward up to 10 years, applied within the same income basket. This lets high foreign taxes in one year offset U.S. tax on foreign income in a year when your limitation has room.
The one exception is the section 951A (GILTI) basket, where no carryback or carryforward is allowed. Excess credits in that basket are lost if unused in the year they arise.
Carryovers are only available if you file Form 1116. If you use the $300/$600 no-1116 election, you forfeit any carryover for that year, which is a reason some filers with excess foreign tax choose to file the form even when the shortcut is available.
FAQ
Do I need to file Form 1116 to claim the foreign tax credit?
Not always. If all your foreign income is passive (mostly interest and dividends) reported on a Form 1099 or Schedule K-1, and your total creditable foreign taxes are $300 or less ($600 or less filing jointly), you may claim the credit directly on Schedule 3 without Form 1116. Estates, trusts, and anyone above those thresholds must file the form.
Is the foreign tax credit better than the foreign earned income exclusion?
It depends on your situation. The credit works best when foreign tax rates are similar to or higher than U.S. rates, because it offsets U.S. tax dollar for dollar and preserves eligibility for refundable credits. The exclusion may help when foreign tax is low. You can sometimes combine strategies, but income excluded elsewhere cannot also generate a foreign tax credit.
What foreign taxes do not qualify for the credit?
Only income taxes, or taxes paid in lieu of an income tax, qualify. Foreign value-added tax, sales tax, property tax, and generally foreign social security taxes do not qualify. Taxes that are refunded to you, subsidized, or that you were not legally required to pay also fail the test, though some nonqualifying taxes may still be deductible.
What is the foreign tax credit limitation?
The limitation caps your credit at the U.S. tax attributable to your foreign-source income, computed as U.S. tax before credits multiplied by the ratio of foreign-source taxable income to total taxable income. It is calculated separately for each income basket. The credit for a basket is the smaller of foreign tax paid or this limit, and it can never reduce U.S. tax on U.S.-source income.
How long can I carry unused foreign tax credits?
Excess foreign tax credits generally carry back 1 year and forward up to 10 years, applied within the same income basket. The section 951A (GILTI) basket is the exception and allows no carryback or carryforward. You must file Form 1116 to preserve carryovers, since the $300/$600 no-1116 election waives them.
Can I claim both a credit and a deduction for foreign taxes?
No, not for the same taxes. You choose one method for all foreign taxes paid or accrued in a given year: either the credit (Form 1116 or the shortcut) or an itemized deduction on Schedule A. The choice is made annually, so you can use the credit one year and the deduction another. The credit usually produces the lower total tax.
