An individual who has paid tax abroad on income also taxable here can claim relief so the same income is not taxed twice over.
The relief is capped rather than pound for pound, computed separately for each category of income, which is why people paying tax abroad at a higher effective rate regularly generate more credit than they can use in the year.
This covers who needs the form and who can skip it, how income is separated into categories, how the limitation is calculated, how unused amounts are carried, and what documentation a claim rests on.
What Is Form 1116?
IRS Form 1116, Foreign Tax Credit, Individual, Estate, or Trust, allows US taxpayers who paid taxes to a foreign country on foreign-source income to claim a credit against their US tax liability. The goal: prevent double taxation, paying both foreign and US tax on the same income.
The relief is capped by reference to what would otherwise have been payable here, which is why people paying tax abroad at a higher effective rate generate more credit than they can use. Model the limitation before the year end and it becomes a plan rather than a surprise.
Ankit Sarawagi, CPA, CA, MBA · LinkedInWho Uses Form 1116?
- Investors who receive dividends from foreign stocks or mutual funds holding foreign securities.
- US citizens and residents living abroad who pay foreign income taxes on local earnings.
- Expatriates paying host-country taxes on wages.
- Anyone who received a 1099-DIV showing foreign taxes paid in Box 7.
The Simple Election: Skip Form 1116 if Small Amounts
If your only foreign taxes paid were from dividends and interest on 1099-DIVs and 1099-INTs, and the total is $300 or less ($600 or less for Married Filing Jointly), you can claim the credit directly on Schedule 3 without filing Form 1116. This simplified election is available only if all foreign income is passive-category income.
Pro Tip: Many investors with foreign dividend ETFs qualify for the simplified election. Check your 1099-DIV Box 7 total, if it is $300/$600 or under, you may not need Form 1116 at all.
Income Baskets (Categories)
The foreign tax credit limitation is calculated separately for each income category (basket). You file a separate Form 1116 for each basket:
- Passive category income, most common for individual investors (dividends, interest, royalties).
- General category income, foreign wages, salaries, and active business income.
- Section 901(j) income, income from countries subject to US sanctions (Cuba, North Korea, Iran, etc.).
- Foreign branch category income, income from a foreign branch of a US business.
- GILTI (Global Intangible Low-Taxed Income), for pass-through owners of CFCs.
How the Credit Limitation Works
The foreign tax credit cannot exceed the US tax attributable to your foreign income. The limitation is calculated as:
Limitation = US Tax x (Foreign Income / Total Worldwide Income)
Example: If your total US tax is $10,000, your foreign income is $5,000, and your worldwide income is $50,000, your limitation is $1,000. Even if you paid $1,500 in foreign taxes, you can only credit $1,000 this year.
Carryback and Carryforward
- Excess foreign taxes can be carried BACK 1 year.
- Remaining excess carries FORWARD 10 years.
- Track your carryover amounts carefully, they are reported on Form 1116 Part III.
How to Complete Form 1116
- Choose the correct income category (basket) for this Form 1116.
- Part I: Identify the foreign country or countries and the type of income.
- Part II: Enter the foreign taxes paid or accrued (from your 1099-DIV, 1099-INT, W-2, or foreign tax records).
- Part III: Calculate the credit limitation.
- Part IV: Determine the allowable credit and any carryover.
- Transfer the allowable credit to Schedule 3, Line 1.
Cash vs. Accrual Method
By default, individuals use the cash method: you claim credit for taxes actually paid during the year. You can elect the accrual method (credit taxes as they accrue), but you must apply it consistently and cannot switch back without IRS permission.

Frequently Asked Questions
Can I take both a deduction and a credit for foreign taxes?
No. You must choose either the foreign tax credit (Form 1116) or a deduction on Schedule A. The credit is almost always more valuable than the deduction.
My mutual fund reported foreign taxes on my 1099-DIV. Do I need Form 1116?
Possibly not. If the total is $300 or less ($600 MFJ) and all income is passive, use the simplified election on Schedule 3 and skip Form 1116.
What if I live abroad and pay substantial foreign taxes?
If you also qualify for the Foreign Earned Income Exclusion (Form 2555), be careful, income excluded under 2555 cannot be used for the foreign tax credit calculation. You generally cannot double-benefit from both exclusion and credit on the same income.
Are foreign taxes from sanctioned countries (Section 901(j)) creditable?
Generally no. Taxes paid to countries with which the US does not have normal relations (Cuba, North Korea, Iran, Syria, Sudan) fall into the Section 901(j) basket and are generally not creditable.
What documentation should be kept to support the claim?
Evidence that the foreign tax was imposed on you and actually paid or accrued: the foreign assessment or return, the receipts, and the conversion rate applied. Keep it with the year's file rather than abroad, because the question, when it comes, will be here. Where the foreign year does not align with the domestic one, note how the amounts were allocated between them.
