Form 1116 Foreign Tax Credit: How to Claim and File for 2025

Overview of What is Form 1116 and its Purpose

Form 1116 Purpose

• Form 1116 is used by individuals, estates, or trusts to claim a foreign tax credit for income taxes paid or accrued to foreign governments on foreign-source income.
• It is required when the taxpayer cannot use the simplified election to claim the foreign tax credit without filing the form.
• The form calculates the allowable foreign tax credit based on the taxpayer’s foreign source income and applicable tax limitations.
• The form requires detailed calculations, including foreign source income, foreign taxes paid, and allocation of credits by income category, with Part IV used to summarize multiple Form 1116 filings.
• Taxpayers must file Form 1116 if their foreign source income includes non-passive income or if their foreign taxes exceed $300 ($600 for joint returns).
• It also addresses special rules for certain types of income, such as lump-sum distributions, income from sanctioned countries, and foreign qualified dividends or capital gains.

Who Needs to File Form 1116?

Who Must File

• Individuals, estates, or trusts who paid or accrued foreign taxes to a foreign country or U.S. territory may file Form 1116 to claim the foreign tax credit.
• Nonresident aliens are not required to file Form 1116 unless they meet specific criteria for claiming the credit.
• Form 1116 is not required if you meet the conditions for the election to claim the foreign tax credit without filing (e.g., passive income, foreign taxes reported on a qualified payee statement, and total creditable taxes ≤ $300 or $600 for joint filers).

Purpose of Form

• Form 1116 is used to claim a credit for foreign income, war profits, and excess profits taxes paid to foreign countries or U.S. territories.
• It helps calculate the allowable foreign tax credit, which reduces U.S. tax liability on foreign-source income.
• Taxpayers may elect to claim the credit without filing Form 1116 if all foreign income is passive and reported on a qualified payee statement (e.g., Form 1099-DIV or 1099-INT).

Filing Requirements

• File Form 1116 if you are an individual, estate, or trust and paid foreign taxes that qualify for the credit.
• Use Schedule B (Form 1116) to reconcile foreign tax carryovers between years.
• Use Schedule C (Form 1116) to report foreign tax redeterminations affecting prior years.

General Instructions

• Use Form 1116 to claim foreign tax credits for taxes paid or accrued during the tax year.
• Ensure all foreign taxes are eligible under section 901 and meet creditability rules.
• Keep records of foreign tax payments and supporting documents for at least three years.

Key Sections Form 1116: Important parts of the form and what they cover

Part I—Taxable Income or Loss From Sources Outside the United States

• Lines 1a and 1b—Foreign Gross Income: Report gross income from foreign sources, categorized by type (e.g., passive or general). If income includes dividends or capital gains, special rules apply. Multiple Forms 1116 may be required for different income types.
• Lines 2 Through 5—Deductions and Losses: Deduct expenses directly related to foreign income (line 2) and allocate a ratable share of other deductions (lines 3a–3b, 4a–4b, and 5) that don’t specifically relate to foreign or U.S. income. Exclude deductions tied to exempt income like foreign earned income excluded on Form 2555.
• Line 3a—Certain itemized deductions or standard deduction: Include itemized deductions such as medical expenses, real estate taxes, and state/local personal property taxes. If not itemizing, enter the standard deduction.
• Line 3b—Other deductions: Report deductions not tied to specific income types, such as those from Schedule 1 (Form 1040), Part II. Attach a statement listing these expenses.
• Line 3d—Gross foreign source income: Enter total gross foreign income for the category selected, including excluded foreign earned income but excluding other exempt income.
• Line 3e—Gross income from all sources: Report total gross income from all sources, including U.S. and foreign, before deductions.
• Line 3f—Divide line 3d by line 3e: Calculate the ratio of foreign to total gross income, rounded to four decimal places, for allocation purposes.
• Line 4a—Home mortgage interest: Allocate home mortgage interest using a gross income method if foreign income exceeds $5,000; otherwise, allocate entirely to U.S. source income.
• Line 4b—Other interest expense: Allocate interest expenses (investment, business, student loans, etc.) using an asset method if foreign income exceeds $5,000; otherwise, allocate entirely to U.S. source income.
• Line 5—Losses from foreign sources: Deduct losses directly related to foreign income. Do not include losses from exempt or excluded income.

Part II: Foreign Taxes Paid or Accrued

• Reports foreign income taxes paid or accrued during the tax year.
• Includes taxes withheld on dividends, interest, or other foreign-source income.
• Taxpayers specify currency and country of tax payment and convert amounts to U.S. dollars.
• Accounts for carryover or carryback of unused foreign taxes from prior years.

Part III—Figuring the Credit

• Line 10 – Enter the sum of any carryover of foreign taxes (from Schedule B, line 3, column (xiv)) plus any carrybacks to the current tax year. If you enter an amount and don’t need to attach Schedule B, check the box as instructed.
• Line 13 – Taxes reclassified under high tax kickout: Adjust foreign taxes paid or accrued if they relate to passive income treated as other category income due to being high taxed. Enter as a negative number (in parentheses) on the passive category Form 1116 and as a positive number on the other category Form 1116.
• Line 16 – Adjustments to line 15: Recharacterizing income from a separate category does not result in recharacterizing any tax.
• Line 18 – Individuals: Enter the sum of (i) Form 1040, 1040-SR, or 1040-NR, line 11b, minus line 14, and (ii) Schedule 1-A (Form 1040), line 37. Estates and trusts: Enter taxable income without the deduction for exemption.
• Line 19 – Divide line 17 by line 18. If line 18 is zero, enter 0. If line 18 is greater than zero and line 17 is more than line 18, enter 1.
• Line 20 – Individuals: Enter the total of Form 1040, 1040-SR, or 1040-NR, line 16, and Schedule 2 (Form 1040), line 12. Estates and trusts: See instructions. Note: Regular tax liability does not include the section 1411 net investment income tax. Adjustments may be needed based on Form 8978, line 14.
• Line 22 – Increase in limitation (section 960(c)): Report any increase in foreign tax credit limitation due to distributions from a CFC that were previously taxed and excluded from gross income under section 959(a). If the amount exceeds U.S. income tax on line 20, the excess is treated as an overpayment and can be claimed as a refundable credit.
• Line 24 – Enter the smaller of line 14 or line 23. This represents the maximum foreign tax credit allowable for the year. If line 23 is smaller than line 14, refer to Pub. 514 for carryback and carryforward rules.

Part IV—Summary of Separate Credits From Parts III

• Line 33: Enter the smaller of line 20 or line 32. This line is used to determine the allowable foreign tax credit based on the lower of the foreign taxes paid (line 20) or the U.S. tax liability (line 32).
• Note for Line 33: Generally, line 32 will exceed line 20 only if you have U.S. capital gains or qualified dividends that are subject to the capital gain rate differential, which is figured in the Worksheet for Line 18.
  

What's New for Form 1116: Recent tax law changes and updates for the current year

Form 1116, Part IV

• Lines 25 through 32 in Part IV must now be completed even when filing only one Form 1116.
• The text on Form 1116, line 24, has been revised to reflect this change.

New legislation

• Recent legislation (P.L. 119-21) adds a $6,000 deduction for taxpayers and their spouses (if age 65 or older by the end of the tax year), reported on Schedule 1-A (Form 1040), line 37.
• This deduction must be removed from taxable income when computing the foreign tax credit limitation and applies for tax years 2025 through 2028.
• P.L. 119-21 also adds section 960(d)(4), which disallows a credit under section 901 for 10% of foreign income taxes paid or accrued with respect to amounts excluded under section 959(a) due to inclusions under section 951A(a), effective after June 28, 2025.

Taxpayers Affected by Form 1116 Updates

Key Changes and Affected Taxpayers

• Taxpayers claiming foreign tax credits must now complete lines 25 through 32 in Part IV of Form 1116, even when filing only one Form 1116. This change affects all taxpayers using Form 1116, regardless of the number of forms filed.
• Taxpayers aged 65 or older (or joint filers where either spouse is 65 or older) are affected by new legislation (P.L. 119-21), which introduces a $6,000 deduction for tax years 2025 through 2028. This deduction must be excluded from taxable income when computing the foreign tax credit limitation.
• Taxpayers with foreign income taxed under section 951A (such as passive foreign investment company income) are affected by new rules disallowing a credit for 10% of foreign taxes paid on amounts excluded under section 959(a) due to section 951A inclusions, effective after June 28, 2025.
• Taxpayers experiencing foreign tax redeterminations (e.g., refunds of previously claimed foreign taxes, changes in foreign tax liability, or contested foreign taxes) must file amended returns with revised Form 1116 and may need to attach Schedule C (Form 1116) to report redeterminations affecting prior years.
• Taxpayers carrying forward or back unused foreign taxes must use Schedule B (Form 1116) to reconcile carryovers, and no carrybacks or carryforwards are allowed for section 951A category income.
  

Example Scenario Showing How the Form 1116 Changes Apply

Form 1116, Part IV

• Martha, a U.S. citizen living in Germany, earns foreign income from a rental property and files Form 1116 to claim a foreign tax credit. Previously, if she filed only one Form 1116, she could skip Part IV lines 25 through 32. Now, even with a single Form 1116, she must complete those lines to reconcile her foreign tax credit calculation.
• The change ensures consistency in reporting, regardless of how many Forms 1116 are filed. Martha now fills out lines 25–32 to show her foreign tax credit limitation and carryover details, even though she’s only claiming one category of income.
• Before the change, she might have omitted these lines, potentially leading to errors or IRS inquiries. Now, her return is more transparent and compliant with updated IRS requirements.
• She updates her Form 1116 accordingly, completing Part IV fully, which helps prevent future adjustments or audits.

New legislation

• David and Linda, a married couple aged 67 and 69, file a joint return for tax year 2025. They receive a $6,000 deduction under new section 151(d)(5)(C) for being over age 65, which is reported on Schedule 1-A (Form 1040), line 37.
• When calculating their foreign tax credit limitation on Form 1116, they must remove this $6,000 deduction from their taxable income to determine the correct credit base. This adjustment ensures the foreign tax credit is computed on the proper taxable income amount.
• Without this adjustment, their foreign tax credit would be based on a higher taxable income, potentially leading to an over-claim of the credit. The IRS requires this exclusion to maintain accuracy in the credit calculation.
• They adjust their Form 1116 by reducing their taxable income by $6,000 before computing the foreign tax credit limitation, ensuring compliance with P.L. 119-21 rules effective for 2025–2028.

Related Schedules and Forms for Form 1116

Form 1040, 1040-SR, or 1040-NR

• Taxpayers must use the Worksheet for Line 18 to determine the tax amount for line 18 of Form 1116 if Schedule D Tax Worksheet line 18 is greater than zero.

Schedule K-1 (Form 1041)

• Schedule K-1 reports income from trusts or estates, and its information is used in Form 1116 to determine foreign tax credits for beneficiaries.

Form 1116 (Schedule B)

• Schedule B of Form 1116 is used for certain income sourced by treaty, helping to identify foreign taxes paid on specific types of income.

Schedule B (Form 1040)

• Schedule B (Form 1040) reports interest and dividend income, and its carryover foreign tax amounts are used in Form 1116 for credit calculations.

Form 1040-X

• Must be filed with a revised Form 1116 and statement if a foreign tax redetermination increases U.S. tax liability for prior years.

Common Mistakes to Avoid on Form 1116

• Incorrect foreign tax calculations: Failing to accurately compute foreign taxes eligible for the credit or misapplying the rate group adjustments on Worksheet B can lead to incorrect credit amounts.
• Missing or incomplete worksheets: Not completing Worksheet B or Line 2 Worksheet properly, especially when dealing with capital gains and losses, may result in an inaccurate foreign tax credit.
• Incorrectly categorizing income: Misclassifying foreign-source income (e.g., short-term vs. long-term capital gains) can distort the credit calculation and lead to errors in the rate group factor application.
• Ignoring negative amounts: Failing to enter losses in parentheses or not properly handling negative values in worksheets can cause miscalculations and processing delays.
• Skipping required attachments: Not attaching necessary schedules or forms, such as Schedule D (Form 1040) or Form 4952, when required, may result in an incomplete return.
• Using wrong filing status or taxpayer info: Entering incorrect names, Social Security numbers, or filing status can invalidate the return, even if Form 1116 is otherwise correct.
• Not reviewing for accuracy: Assuming a preparer’s work is error-free without reviewing the entire return can lead to overlooked mistakes, especially in complex foreign tax credit calculations.
• Incorrectly applying deductions or credits: Claiming foreign tax credits without verifying eligibility or failing to adjust for U.S. source income can result in overclaiming or underclaiming the credit.

Helpful Tips for Completing Form 1116

Qualifying Foreign Taxes

• Ensure the foreign tax meets four tests: imposed on you, paid or accrued, legal and actual foreign tax liability, and an income tax (or tax in lieu of income tax).
• Exclude taxes paid to countries supporting terrorism, not recognized by the U.S., or where diplomatic relations are absent.
• Disqualified taxes include those on dividends without holding stock for at least 16 days within a 31-day period around the ex-dividend date.
• Foreign taxes withheld on income or gain (other than dividends) require holding property for at least 16 days within 31 days before the payment right arises.

Choosing Credit vs. Deduction

• Claim foreign tax credit by completing Form 1116 and attaching it to Form 1040, 1040-SR, or 1040-NR.
• Choose either credit or deduction annually; you cannot claim both for the same taxes.
• Some foreign taxes may still be deductible even if not creditable (e.g., taxes on income not meeting holding period requirements).

Computing the Credit

• The foreign tax credit is limited to the lesser of foreign tax paid or U.S. tax attributable to foreign source income.
• Compute separately for passive income, treaty-based income, section 901(j) income, section 951A income, foreign branch income, and general category income.
• Consider special rules under tax treaties when calculating the credit.

Carryback and Carryover

• Unused foreign tax credit can be carried back 1 year and carried forward up to 10 years.
• No carryback or carryover is allowed for foreign tax on income included under section 951A.

Claiming Without Form 1116

• You may claim the credit without filing Form 1116 if all foreign source income is passive, reported on qualified payee statements (e.g., Form 1099-INT, Form 1099-DIV), and total qualified foreign taxes do not exceed the limit based on filing status.
• All foreign taxes must be legally owed, not eligible for refund, and paid to recognized countries not supporting terrorism.
• This option is not available for estates or trusts, and no carryback or carryover applies.

Amending Returns

• If you claimed a deduction for foreign taxes, you can file an amended return (Form 1040-X) within 10 years to claim a credit instead.
• If you claimed a credit and receive a refund of foreign taxes, file Form 1040-X within the due date (with extensions) of the year the refund was received.
• If you claimed a credit and wish to switch to a deduction for a refund, file Form 1040-X within 3 years from the original due date of your return.
