Form 1116 is the IRS form individuals, estates and trusts use to claim the foreign tax credit for income tax they paid to another country or a US territory. You can skip it and claim the credit straight on your return if all your foreign income was passive (most interest and dividends), it was reported on a form such as a 1099-DIV, and your foreign tax was $300 or less ($600 married filing jointly), as of October 2026.
The credit exists so the same income isn't taxed twice, once abroad and once by the US. Form 1116 is where you prove how much foreign tax you paid and work out the limit: you can't use foreign tax to wipe out US tax on your US income. Everything below comes from the IRS Instructions for Form 1116 for 2025 returns.
Do you need the form or can you use the shortcut?
The IRS calls the shortcut the election to claim the foreign tax credit without filing Form 1116. It's open to individuals only, not estates or trusts, and you need all three of these to be true:
- All your foreign source gross income was passive category income, which includes most interest and dividends.
- All of that income, and the foreign tax paid on it, was reported to you on a qualified payee statement such as Form 1099-DIV, Form 1099-INT, Schedule K-1 (Form 1041) or Schedule K-3.
- Your total creditable foreign taxes aren't more than $300, or $600 on a joint return.
If you qualify, you just enter the smaller of your total foreign tax or your regular tax on the foreign tax credit line of your return, for example Schedule 3 (Form 1040), Part I, line 1. The trade-off: you can't carry any of that year's foreign tax to another year. That's why the shortcut suits someone holding international index funds whose 1099-DIV shows a small amount of foreign tax paid, and not someone earning wages abroad.
Credit or deduction: you choose each year
Instead of the credit you can deduct foreign income taxes as an itemized deduction on Schedule A. For most people the credit is worth more, because it cuts your tax bill directly rather than your taxable income. Generally, if you take the credit for any eligible foreign taxes in a year, you can't deduct any part of that year's foreign taxes, with a few exceptions such as taxes denied a credit by the boycott rules.
The window to change your mind isn't the same both ways. You can switch to the credit at any time before the end of a special 10-year limitation period. You can switch from the credit to the deduction only within the standard 3-year period.
The income categories: one Form 1116 for each
Foreign income is sorted into separate categories, and you complete a separate Form 1116 for each category you have. The IRS example: foreign dividends plus foreign wages means two forms, one with box c checked for the dividends and one with box d checked for the wages.
| Category | What goes in it |
|---|---|
| a. Section 951A | GILTI inclusions of US shareholders in certain controlled foreign corporations |
| b. Foreign branch | Business profits of a US person from a branch abroad |
| c. Passive | Most interest, dividends, rents and royalties, plus certain DISC dividends |
| d. General | Everything not in another category, such as wages and active business income |
| e. Section 901(j) | Income from countries where the credit is denied |
| f. Re-sourced by treaty | Certain income treated as foreign under a tax treaty |
| g. Lump-sum distributions | Lump-sum distributions from a foreign source |
Getting the category right matters because the limit is worked out category by category. High foreign tax on wages can't be used to cover the US tax on lightly taxed foreign dividends.
Taxes you can't claim
The credit covers income, war profits and excess profits taxes paid to a foreign country or US territory, including a state, province or city there. It doesn't cover tax you didn't legally owe. The IRS example: Country X withholds $25 from a payment, but under the treaty you only owe $15 and could reclaim $10. Only $15 is creditable, whether or not you apply for the refund.
- Foreign tax offset or reduced by a foreign tax credit, unless that credit is fully refundable in cash at your option.
- Tax withheld on a dividend if you held the stock for fewer than 16 days in the 31-day period that starts 15 days before the ex-dividend date.
- Tax paid to countries designated as supporting international terrorism or with which the US has no diplomatic relations (Pub. 514 has the list).
- Tax imposed only because you could claim a US credit for it.
Carryback and carryforward
If you paid more foreign tax in a category than the limit lets you use, the unused amount isn't lost. You can carry it back 1 year and then forward 10 years, applying it to the earliest year first. Schedule B (Form 1116) reconciles the carryover. Two catches: there are no carryovers at all for section 951A category income, and you can't carry a credit back to a year in which you deducted foreign taxes instead.

What changed for 2025 returns
- Part IV, lines 25 through 32, must now be completed even when you file only one Form 1116.
- P.L. 119-21 added a $6,000 deduction for taxpayers aged 65 or over (each spouse on a joint return), reported on Schedule 1-A. It has to be removed from taxable income when you figure the foreign tax credit limit. It applies for tax years 2025 through 2028.
- If foreign tax on passive income is reported to you in US dollars on a 1099-DIV or 1099-INT, you don't have to convert it; enter '1099 taxes' in column (l) of Part II.
If you hold accounts abroad as well as earning income there, the credit is only half the paperwork. Check whether you also need an FBAR for the accounts themselves.
The verdict
Look at your 1099s first. If the only foreign tax you paid came through funds and it's under $300 ($600 joint), skip Form 1116 and claim it in one line. If you earned wages or business income abroad, file the form, one per category, and keep the carryover schedule, because the excess you can't use this year is worth something for the next 10.

Frequently asked questions
Is Form 1116 always needed to claim the foreign tax credit?
Not always. If all your foreign income was passive, reported on a form such as a 1099-DIV, and your foreign tax was $300 or less ($600 joint), you can claim it directly on your return.
Can I deduct foreign taxes instead of claiming the credit?
Yes. You can deduct foreign income taxes on Schedule A instead, but generally not both in the same year.
How long can I carry unused foreign tax forward?
You can carry unused foreign tax back 1 year and then forward 10 years. There are no carryovers for section 951A category income.
Do I need more than one Form 1116?
Yes, if you have income in more than one category. Foreign dividends and foreign wages, for example, need two forms.
