How to file Form 1116: foreign tax credit example for US expats

If you earned income outside the US in 2025 and paid foreign income tax on it, Form 1116 is the form that may reduce your US tax when you file in 2026. This guide explains who files it, how the limitation works, and how the credit flows to Schedule 3 – with a full worked example using two income categories.

• Who Form 1116 is for: US citizens, resident aliens, green card holders, and certain nonresident aliens who paid or accrued creditable foreign income taxes on foreign-source income.
• What the foreign tax credit does: The credit reduces US income tax dollar-for-dollar, but only up to the US tax attributable to the foreign-source income in that category.
• When the simplified option may apply: If your total creditable foreign taxes are $300 or less ($600 or less if married filing jointly), all foreign income is passive category income, and all income and taxes are on qualified payee statements, you may claim the credit directly on Schedule 3 without filing Form 1116.

Form 1116 at a glance

Form 1116 is usually required when your 2025 foreign taxes exceed $300 if single or $600 if married filing jointly, or when your foreign income is not limited to passive income reported on qualified payee statements.

The IRS foreign tax credit Form 1116 connects four things: your foreign-source income, the foreign taxes you paid, your US taxable income, and the allowable credit for each income category.

 

The FTC offsets US tax on foreign-source income – it does not reduce the foreign tax itself. It prevents the same income from being taxed twice: once by the foreign country and once by the United States.

A federal foreign tax credit form is not needed for every taxpayer with foreign income. If you meet all four conditions for the simplified election – passive-only income, qualified payee statements, foreign taxes at or below $300/$600, and the Schedule 3 election – you may skip the form entirely.

The foreign tax return form you receive from a foreign country – such as a pay slip, withholding certificate, or foreign tax assessment – is not the same as Form 1116 itself, but those foreign documents supply the numbers you enter on Form 1116.

What is IRS tax form 1116?

IRS Form 1116 is the form individuals, estates, and trusts use to calculate the foreign tax credit for 2025 foreign income taxes paid or accrued. The credit can reduce US income tax, but it does not reduce self-employment tax or create a refundable credit in ordinary cases.

The foreign tax credit form is the mechanism the IRS uses to prevent double taxation on foreign-source income. It connects four elements: what you earned abroad, what foreign tax you paid, what US tax applies to that income, and how much credit you can claim.

Mini glossary:

• Foreign-source income: Income earned in or attributable to a foreign country – wages for work performed abroad, dividends from foreign corporations, rental income from foreign property.
• Foreign taxes paid or accrued: Creditable foreign income taxes you actually paid or properly accrued under your accounting method during the tax year.
• Credit vs. deduction: A credit reduces your tax dollar-for-dollar. A deduction reduces your taxable income. The credit is usually more valuable.
• Schedule 3: The form where the final foreign tax credit from Form 1116 line 35 is reported on your individual return.

The IRS form for the foreign tax credit – officially Form 1116 – covers foreign income taxes, war profits taxes, excess profits taxes, and certain taxes in lieu of income tax. It does not apply to VAT, ordinary sales taxes, or property taxes because those are not income taxes.

For a broader return overview, see our Form 1040 guide for expats.

When is Form 1116 required?

Form 1116 is required for most 2025 foreign tax credit claims unless the narrow simplified election applies.

The Form 1116 requirements apply when any of these conditions is true:

• You paid or accrued foreign income tax on 2025 foreign wages, self-employment income, business income, rental income, or other general category income
• You paid more than $300 in creditable foreign taxes if single, or more than $600 if married filing jointly
• Your foreign income was not all passive category income
• Your foreign income and foreign taxes were not fully reported on qualified payee statements such as Form 1099-DIV, Form 1099-INT, Schedule K-1 (Form 1041), or Schedule K-3 (Form 1065 or Form 1120-S)
• You want to preserve foreign tax credit carryovers or carrybacks for the current year. Electing the simplified option forfeits any carryover to or from that year, even though prior-year carryovers don’t disqualify you from the election itself, per the IRS Form 1116 instructions

Form 1116 is not required when all four of these conditions are met at the same time:

• All foreign-source gross income is passive category income
• All foreign income and foreign taxes are reported on qualified payee statements
• Total creditable foreign taxes are $300 or less, or $600 or less if married filing jointly
• You elect to claim the credit directly on Schedule 3 instead of filing Form 1116

Decision tree for 2025 returns – four steps:

1. Did you pay or accrue foreign income taxes in 2025? If no → Form 1116 usually does not apply. If yes → continue.
2. Are your total creditable foreign taxes $300 or less ($600 or less on a joint return)? If no → you usually need Form 1116. If yes → continue.
3. Was all foreign-source gross income passive category income reported on qualified payee statements? If no → you usually need Form 1116. If yes → continue.
4. Are you electing the simplified claim on Schedule 3? If yes → you may skip Form 1116. If no → file Form 1116.

Form 1116 simplified filing threshold

You can claim the foreign tax credit without filing Form 1116 only when every condition in the simplified election is met. This is a narrow exception, not a general rule.

 

If any condition is not met, the simplified threshold does not apply and you need Form 1116.

You cannot claim the foreign tax credit without filing Form 1116 if you have foreign wages, self-employment income, rental income, carryovers, or creditable taxes above the $300/$600 limit.

Practical check: Most US expats with a foreign salary will not qualify for the simplified election because wages are general category income, not passive.

Form 1116 vs Form 2555: the difference

Form 1116 claims a credit for creditable foreign income taxes, while Form 2555 excludes qualifying foreign earned income from US taxable income. For the 2025 tax year, the foreign earned income exclusion is capped at $130,000 (2025) per qualifying person.

Both tools reduce double taxation, but they work differently. Federal tax Form 1116 can apply to earned and passive income, while Form 2555 applies only to foreign earned income and requires a tax home abroad plus either the bona fide residence test or the physical presence test.

 

Decision rule: In a high-tax country, Form 1116 often produces a stronger result. In a no-tax or low-tax country, Form 2555 may be more useful. Families with qualifying children often need a careful comparison because using Form 2555 can reduce taxable earned income and may affect refundable credit outcomes.

Read our full foreign earned income exclusion guide for eligibility details.

Who can claim the foreign tax credit: Form 1116 filing requirements

US citizens, resident aliens, and green card holders can generally claim the foreign tax credit when they paid or accrued qualified foreign income taxes on foreign-source income that is also subject to US tax. The Form 1116 filing requirements apply separately from the broader question of whether you must file a Form 1040.

For 2025 returns, a foreign tax must meet four IRS tests before it is creditable:

1. Imposed on you – the tax must be your legal liability, not someone else’s.
2. Paid or accrued – the tax must have been actually paid or properly accrued under your method during the tax year.
3. Legal and actual liability – the tax must be the final foreign income tax assessed under local law, not a refundable subsidy or a contested amount.
4. Income tax or tax in lieu of income tax – the levy must be a net income tax or a qualifying substitute, not VAT, sales tax, property tax, or non-creditable social security tax.

Four taxpayer groups should check eligibility:

• US citizens: Report worldwide income and may claim credits for qualified foreign income taxes on foreign-source income.
• Resident aliens: Generally follow the same foreign tax credit rules as US citizens.
• Green card holders: Usually resident aliens for US tax purposes and generally report worldwide income.
• Certain nonresident aliens: Generally cannot claim the credit, except in limited cases such as being a resident of Puerto Rico for the full tax year.

If your immigration status changed during 2025, read our alien tax status guide.

For a broader overview of US expat tax rules, see the TFX guide.

Foreign tax credit eligibility checklist

Use this checklist to confirm eligibility before completing Form 1116. All items should be yes for the credit to apply.

• You are a US citizen, resident alien, or green card holder (or a qualifying nonresident alien)
• You earned foreign-source income that is included in your US gross income
• You paid or accrued a foreign tax that is legally your liability
• The foreign tax is an income tax or a tax in lieu of income tax – not VAT, sales tax, property tax, or a penalty
• The tax was paid or accrued to a foreign country or US territory, not to the United States
• The income was not excluded on Form 2555 (or, if partially excluded, you are reducing the foreign taxes allocable to the excluded portion)

If any answer is uncertain, review the IRS eligibility tool or consult a preparer before filing.

What qualifies and what does not qualify for the foreign tax credit

A foreign tax generally qualifies only if it is imposed on you, paid or accrued by you, legally owed, and is an income tax or a tax in lieu of income tax. Use Form 1116 for foreign tax paid that meets all four tests.

 

Many foreign levies are deductible or reportable elsewhere on your return but are not creditable on Form 1116.

The IRS also disallows credits for foreign taxes on income excluded under Form 2555. If only part of your foreign wages are excluded, the foreign taxes must be reduced by the amount allocable to the excluded income.

For a broader overview, see our guide to the foreign tax credit for US expats.

If you earned income in a country with no personal income tax, review our guide to tax documents needed from countries with no personal tax.

Worked example: A US expat in Spain has $50,000 of 2025 foreign-source taxable wages, $100,000 of worldwide taxable income, and $12,000 of US income tax before credits.

• $50,000 ÷ $100,000 = 50%
• 50% × $12,000 = $6,000 maximum credit
• Spain withheld $8,000 of creditable income tax → current-year general category credit is capped at $6,000, with $2,000 as excess foreign tax subject to carryover rules

Foreign taxes paid on Form 1116 are reported in Part II by country. If taxes were withheld on multiple pay dates, do not assume a single yearly average rate is correct – the IRS generally uses the exchange rate on each payment or withholding date unless an exception applies.

Unused credits may carry back 1 year and forward 10 years within the same category, following the foreign tax credit carryover rules. Corporations use different rules, which we cover in our Form 1118 foreign tax credit guide.

Categories of income

Form 1116 generally requires a separate form for each foreign-source income category you have in 2025. The Form 1116 categories of income determine which basket each type of foreign income falls into and how the limitation applies.

 

Misclassifying income can reduce, delay, or invalidate the credit. Passive income and general wages should not be combined on one Form 1116 just because both amounts came from the same country.

For expats with foreign dividends, the passive category is usually the correct basket.

Section 960(d)(4) disallows a credit for 10% of certain foreign income taxes paid or accrued on distributions that are excluded from gross income under section 959(a) because they represent previously taxed income from an earlier section 951A (GILTI) inclusion. This rule applies to taxes paid or accrued after June 28, 2025, and affects 2025 returns filed in 2026.

The limitation equation

The foreign tax credit limitation uses foreign-source taxable income in the relevant category, worldwide taxable income, and US tax – not simply gross foreign income divided by worldwide gross income.

Formula:

Foreign tax credit limit = (foreign-source taxable income in the category ÷ worldwide taxable income) × US tax against which the credit is allowed

Three variables drive the limitation:

• Foreign-source taxable income in the category: Net income from foreign sources after required deductions, allocations, and adjustments.
• Worldwide taxable income: Your taxable income base for Form 1116 line 18, with 2025-specific adjustments. For 2025, taxpayers age 65 or older must add back the new $6,000 senior deduction (P.L. 119-21, reported on Schedule 1-A (Form 1040), line 37) to the Form 1116 line 18 taxable income figure – the deduction reduces Form 1040 taxable income but is not allowed to reduce the foreign tax credit limitation.
• US tax against which the credit is allowed: For individuals, line 20 generally starts with Form 1040 line 16 plus the applicable Schedule 2 (Form 1040) tax amount specified in the Form 1116 instructions.

What does “Form 1116 gross income from all sources” mean?

It refers to the line 3e concept used for allocating certain deductions: gross income from all sources and categories, both US and foreign. It is not the same as the final limitation denominator on line 18.

Worked example: A US expat has $78,000 of foreign-source taxable wages, $90,000 of worldwide taxable income, and $13,500 of US tax before credits.

• Foreign-source taxable income in the general category: $78,000
• Worldwide taxable income: $90,000
• Ratio: $78,000 ÷ $90,000 = 86.67%
• Limitation: 86.67% × $13,500 = $11,700

If foreign tax paid is $16,000 but the Form 1116 limit is $11,700, the 2025 current-year credit is $11,700. The remaining $4,300 may be excess foreign tax subject to carryback and carryforward rules.

Carryback and carryover

Unused foreign tax credits generally carry back 1 year and carry forward 10 years, but only within the same separate income category. Section 951A category income does not allow foreign tax credit carrybacks or carryovers.

Carryover timeline:

 

Track three items each year:

• Category of income – passive, general, or other
• Year the excess credit arose
• Amount used, carried back, carried forward, or expired

Schedule B (Form 1116) reconciles foreign tax carryovers by category. This is not the same as Schedule B (Form 1040), which reports interest, dividends, and foreign account questions.

Keep at least 10 tax years of Form 1116 carryover records, plus proof of the original foreign tax payments. The IRS instructions require books or records to be retained as long as they may become material in administering the tax law.

For document retention guidance, see the TFX guide on how long to keep tax records.

Form 1116 foreign tax credit example

This example uses two separate income categories for a 2025 US expat return: passive dividends and general foreign wages. Because each category has its own limitation, the taxpayer files two Forms 1116 and summarizes the allowed credits in Part IV.

Scenario: The taxpayer earned $78,000 in foreign wages, received $2,000 in foreign dividends, paid $16,000 of foreign income tax on wages, and had $300 of foreign dividend tax withheld. Worldwide taxable income is $90,000, and US tax before credits is $13,500.

 

The combined 2025 foreign tax credit is $12,000 before any additional limitations or unusual adjustments. The $4,300 excess general category tax may be available for carryback or carryforward if the rules are met.

Form 1116 example with a mutual fund: If the taxpayer also held a foreign mutual fund that paid $500 of foreign dividends with $75 of foreign tax withheld, those amounts would be added to the passive Form 1116. The passive limitation would increase, and the $75 of additional foreign tax would be tested against the new passive limit.

#1 – Passive category: dividends on 1099-DIV

The passive category example uses $2,000 of foreign dividends and $300 of foreign tax withheld. Form 1116 passive income from dividends is usually simple to calculate when the amounts are small and reported on qualified payee statements.

 

The passive category income on Form 1116 is allowed only up to the smaller of the foreign tax paid or the category limitation. In this case, both equal $300.

Final credit may differ once all Form 1116 adjustments are applied, especially if the taxpayer has qualified dividends, capital gains, allocable deductions, or high-taxed passive income.

To understand the dividend reporting context, read our guide to Form 1099-DIV.

#2 – General category: foreign wages

The general category wage example uses $78,000 of foreign-source taxable wages and $16,000 of foreign income tax paid. General category income on Form 1116 is usually where foreign wages belong because they come from personal services performed abroad.

 

The taxpayer paid $16,000 abroad, but Form 1116 caps the current-year general category credit at $11,700. The unused $4,300 is tracked separately as general category excess foreign tax.

The allowed credit flows from Part III to Part IV, then to Schedule 3 (Form 1040), line 1. For wage reporting, see our Form W-2 guide, and for self-employment issues, read our guide to self-employed expats and double taxation.

Part IV + where the final credit goes

Part IV summarizes credits from multiple Forms 1116. For 2025, lines 25–32 must be completed even when only one Form 1116 is filed. The final credit on Form 1116 line 35 carries to Schedule 3 (Form 1040), line 1.

 

Cross-check the total on Form 1116 line 35 against Schedule 3 line 1 before filing. For related return mapping, see our guide to Form 1040 Schedule 2.

High-tax kickout rule

The high-tax kickout on Form 1116 applies when passive income is taxed abroad at a rate that exceeds the highest US tax that can be imposed on that income after expense allocation. In that case, the passive income is reclassified into another category.

Why it matters:

• It can move income and taxes out of the passive basket
• It can change the limitation calculation for more than one Form 1116
• It can affect whether excess foreign taxes are trapped in a category

The reclassified amount is reported with “HTKO” entries on both the passive Form 1116 and the other category form.

Example: A US expat receives $5,000 in foreign-source interest taxed abroad at 40% after expense allocation. The highest US tax that can be imposed on that income is 37%. Because the foreign rate exceeds the US rate, the $5,000 and its $2,000 of foreign tax are removed from the passive Form 1116 and reported in the applicable general category form instead. Both limitations change.

Caution: Do not compare a foreign withholding rate to the US qualified dividend rate alone. The IRS test depends on foreign taxes paid on the income after expense allocation and the highest US tax that can be imposed on that income.

For related GILTI issues, read our guide to the GILTI high-tax exception.

Understanding the structure of Form 1116

Federal Form 1116 is built around four main parts: foreign-source income, foreign taxes paid or accrued, the limitation calculation, and the summary of separate credits. For 2025, Part IV lines 25–32 must be completed even if you file only one Form 1116.

Each Form 1116 applies to only one income category checked above Part I. If you have both foreign wages and foreign dividends, your return generally includes two Forms 1116 plus one summary Part IV.

 

Schedule B (Form 1116) is not the same as Schedule B (Form 1040). See our Form 1040 Schedule B guide if you also have interest, dividends, or foreign account questions on the main return.

Five lines to verify before filing:

• Line 1a – foreign gross income by category
• Lines 2–6 – deductions and allocations
• Line 8 – total foreign taxes paid or accrued
• Line 10 – carryovers and carrybacks, supported by Schedule B where required
• Line 35 – final credit that should match Schedule 3

If you attach a conversion explanation, include three details: the exchange-rate source, the date or period used, and whether the tax was paid or accrued. The IRS instructions specifically require a detailed explanation when foreign currency is converted.

For document prep, review our expat IRS tax form checklist and our ultimate tax documents checklist.

Form 1116 checklist before you file

A short pre-filing checklist can prevent the most common Form 1116 errors. If you need Form 1116 help, use this checklist before submitting a 2025 return in 2026.

Income classification

• Passive, general, and other categories are on separate Forms 1116
• The foreign levy is confirmed as an income tax or a tax in lieu of income tax
• VAT, sales tax, property tax, interest, and penalties are excluded from the credit

→ If missing: Review your foreign tax documents and reclassify any non-income levies before completing Part II.

Form 2555 coordination

• Foreign taxes are reduced for any income excluded on Form 2555

→ If missing: Recalculate the allocable portion of foreign taxes before entering amounts on Form 1116.

Currency and conversion

• Foreign tax paid is converted using the correct payment-date or withholding-date exchange rate, unless an exception applies

→ If missing: Gather exchange-rate documentation for each payment date and attach an explanation statement if needed.

Carryovers and documentation

• Schedule B (Form 1116) is attached if carryovers are used or generated
• Proof of foreign tax paid, withheld, accrued, refunded, or reassessed is attached or retained
• Form 1116 line 35 matches Schedule 3 line 1

→ If missing: Pull prior-year Forms 1116, reconcile carryover amounts by category, and cross-check the final credit against Schedule 3.

Form 1116 explanation statement

A Form 1116 explanation statement may be useful when a 2025 return includes unusual currency conversion, foreign tax refunds, amended foreign assessments, contested taxes, or complex allocations.

Five situations that may justify or require a short statement:

• Foreign currency conversion uses multiple payment dates or a non-obvious rate source
• A foreign tax refund, audit adjustment, or amended return changes taxes reported in a prior year
• Deductions were allocated across US and foreign income using a method that needs context
• High-tax kickout entries move income from passive to another category
• A treaty-based sourcing position or uncertain disclosure may need separate support

Sample template:

“Taxpayer translated 2025 foreign income tax withheld on monthly payroll using the exchange rate in effect on each withholding date and attached a schedule showing the date, foreign currency amount, rate used, and US-dollar result.”

A Form 1116 explanation statement is not a substitute for the form instructions. For return positions that are not otherwise adequately disclosed, Form 8275 may be relevant.

Common mistakes to avoid

The most common Form 1116 mistakes can change the credit or trigger IRS correspondence.

 

If a mistake has already been filed, see our guide on amending an expat tax return with Form 1040-X.

Filing Form 1116 feels overwhelming?

Form 1116 can involve two or more forms, multiple currencies, and category-by-category carryovers when you have wages, investments, and foreign tax refunds in the same year.

Who benefits most from professional help:

• Taxpayers with income in more than one category – passive dividends plus general wages, for example
• Expats with carryovers from prior years that need to be reconciled on Schedule B
• Filers who also use Form 2555 and need to reduce foreign taxes allocable to excluded income
• Taxpayers with foreign tax statements in a language other than English

If your return includes foreign wages, dividends, carryovers, or Form 2555 decisions, a second look can prevent expensive mistakes. Read our guide on whether to hire an expat tax professional.
