How to claim Foreign Tax Credit on your U.S. Tax Return

Outbound Articles

22 Mar 2026

If you’re a U.S. citizen or tax resident, you may be subject to U.S. tax on your worldwide income. This means that you may be taxed on the income you earn from other countries.

This could mean paying taxes twice on the same income: once to a foreign country and again to the U.S. That’s where the foreign tax credit may help.

Think of it as the IRS saying, “If you’ve already paid taxes on that money elsewhere, we’ll give you credit for it.”

For example, if you earned $10,000 in another country and paid $1,500 in taxes there, Form 1116 may reduce your U.S. tax bill by up to $1,500.

You may be able to claim the Foreign Tax Credit (FTC) by filing Form 1116, although in some cases Form 1116 is not required. You may be eligible to skip filing Form 1116 and claim the credit on Schedule 3 of Form 1040 if you meet certain conditions. You may also elect to deduct foreign taxes as an itemized deduction instead of taking the credit.

Claiming the credit is usually preferred over the deduction. This is because the Foreign Tax Credit generally reduces your U.S. tax liability dollar-for-dollar for income taxes paid to a foreign country, subject to limitations. By contrast, deducting foreign taxes only lowers your

Let us understand how you can claim your foreign tax credit through Form 1116.

Steps to Claim the Foreign Tax Credit

You can claim the foreign tax credit through the following steps:

Determine Eligibility for the Foreign Tax Credit

First, it is important to check whether you are eligible for the foreign tax credit. The following are the eligibility requirements that you should check:

  • You should be a U.S. citizen or a U.S. resident alien.
  • You paid foreign taxes on income that’s also subject to U.S. taxation. This is because the foreign tax credit is claimed for tax paid to a foreign nation on income that is also taxable in the United States.
  • Verify the foreign taxes were legally owed and not refundable.
  • Ensure that the foreign taxes qualify for the credit. Not all payments made to a foreign government are eligible. For instance, taxes that can only be claimed as an itemized deduction generally do not qualify for the Foreign Tax Credit.
Determine If You Need to File Form 1116

Confirm that you qualify to claim the foreign tax credit through Form 1116. You may be eligible to skip filing Form 1116 and claim the credit on Schedule 3 of Form 1040 if you meet all of the following conditions:

  1. Your only foreign income is passive income (like interest or dividends).
  2. The total foreign taxes you paid are $300 or less (or $600 or less if filing jointly).
  3. All your foreign income and taxes are shown on an information form you received (like Form 1099-DIV or 1099-INT).
  4. You choose to use this simplified method for the year. Please note that if you chose this method, then you may not be eligible to carry back or carry over any unused foreign tax.

If you don’t meet the above conditions, you are required to file Form 1116 with your U.S. tax return.

Gather Required Documentation

Begin by gathering all the necessary items to report your foreign income and taxes. According to the IRS, you should maintain these documents in case you are later asked to verify the amounts reported on Form 1116, Form 1040, Form 1040-SR, or Form 1040-NR. These records are not filed with your return.

Documentation needed includes the following:

  • Receipts for each foreign tax payment,
  • Any foreign tax return if you claim a credit for taxes accrued, and
  • Any payee statements, such as Form 1099-DIV or Form 1099-INT, reporting foreign taxes.

Proof should be kept as the original, a duplicate original, or a certified/authenticated copy. If the records are in a foreign language, a certified translation is required. (See Revenue Ruling 67-308, C.B. 1967-2 for details.)

Complete Form 1116

If you choose to take the credit, you should complete IRS Form 1116, “Foreign Tax Credit.” This form involves reporting the sources of foreign income, any taxes paid on that income, and the amounts you are eligible to claim as a credit.

Here is a summarized guide for the key steps to complete Form 1116:

a. Identify the income categories:

Taxpayers are required to split up their foreign income into specific categories, such as passive income, general income, foreign branch income, etc. A separate Form 1116 will need to be completed for each category of income.

Foreign income should be separated into specific categories:

  • IRC 951A Category Income
  • Foreign Branch Category Income
  • Passive category income
  • General category income
  • Section 901(j) income
  • Certain Income Re-sourced by Treaty
  • Lump-sum Distributions

b. Part I: Report foreign source income by category

This part of Form 1116 requires taxpayers to calculate their taxable income from sources outside of the United States. There are several columns on this part of the form. If the taxpayer has foreign income attributable to more than one country, a separate column must be used for each country. After the net foreign source taxable income is calculated, this amount is then carried to part III of Form 1116.

c. Part II: Report foreign taxes paid or accrued by country

This part of Form 1116 asks the taxpayer to report the amount of foreign taxes that were paid or accrued in the current year. The total foreign taxes paid or accrued is then carried to part III of Form 1116.

d. Part III: Calculate Your Foreign Tax Credit Limitation

This part of Form 1116 computes the amount of credit eligible to be claimed on the taxpayer’s return.

The primary goal of these calculations is to distinguish between foreign income and U.S.-sourced income, as well as to separate taxes paid on foreign income from those paid on U.S. income. Once this separation is achieved, we can determine the amount of credit available for foreign taxes paid.

To calculate the credit, the total foreign taxes paid during the tax year is compared to the foreign tax credit limitation. The limitation is computed as follows:

(Foreign income ÷ Total income) × U.S. tax liability = Maximum FTC

Finally, the foreign tax credit is claimed by taking the lesser of the foreign taxes paid during the year or the limitation as calculated above.

Example Calculation

John is a U.S. citizen residing in Canada. He earns $100,000 and pays $25,000 in Canadian income tax. His total taxable income, which includes his U.S. investments, amounts to $120,000. Before any credits, his U.S. tax liability is $30,000.

Based on his income, John’s Foreign Tax Credit (FTC) limit is calculated to be $25,000. This is determined using the formula: (100,000 ÷ 120,000) × 30,000 = 25,000). Therefore, John can apply the full $25,000 of his FTC this year.

It’s important to note that the FTC limit ensures that the credit cannot exceed the U.S. tax owed on foreign income. In other words, while the FTC can reduce his U.S. tax liability to $0, it will not result in any tax refund.

e. Part IV:  Determine Your Final Credit Amount

This part totals all the foreign tax credits from the various categories of income. The final figure represents the total credit that can be applied against the taxpayer’s U.S. tax liability for the year. The credit amount is limited to the lesser of the total foreign taxes paid or the U.S. tax liability attributable to foreign source income. Any excess can be carried back 1 year or forward up to 10 years.

Apply the Credit to Your Tax Return

Once the form is complete, attach it to your Form 1040 or Form 1040-SR. Include all supporting documentation and double-check for missing information or math errors.

The credit will then be part of your calculations for your overall tax payment.

You can e-file your return or mail it in, depending on your situation.

Track Carryovers and Keep Records

If you have unused foreign taxes, record them accurately.  You are allowed to carry over the portion of your foreign tax credit that has not been used for a period of up to 10 years.

Keep copies of Form 1116, your tax return, and all related documents. These records may be needed for IRS review or to apply unused credits in the future. This is crucial not only for IRS compliance but also for ensuring you can substantiate your claim should the IRS request more information or audit your tax return.

Conclusion

The Foreign Tax Credit is a useful tool for those who pay taxes in multiple countries, ensuring they are not unduly penalized by dual tax obligations.

Understanding how to properly apply for this credit can result in substantial tax savings and compliance with U.S. tax laws.
