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 may help reduce your 2026 US tax bill. This 1116 foreign tax credit guide explains who files the form, how the limitation works, and how the credit flows to Schedule 3.
- Who Form 1116 is for: US citizens, resident aliens, green card holders, and certain nonresident aliens use Form 1116 when they paid or accrued creditable foreign 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 category.
- When this example applies: The worked examples below apply to a 2025 US expat return filed in 2026 with foreign wages, foreign dividends, and foreign taxes paid in more than 1 income category.

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 statements. These rules decide whether you file the form or claim the credit directly on Schedule 3.
Key takeaways for 2025 returns filed in 2026
- Most US expats need Form 1116 when claiming foreign tax credits for wages, self-employment income, rental income, or mixed income categories.
- The $300/$600 exception applies only when all foreign-source gross income is passive category income and the income and taxes are reported on qualified payee statements.
- Each income basket, such as passive category income or general category income, generally needs its own Form 1116.
- The credit is limited to the US tax on foreign-source taxable income in that category, not necessarily the full foreign tax paid.
- Check the current Form 1116 instructions or work with a preparer before filing if you have carryovers, foreign tax refunds, high-taxed passive income, or Form 2555 exclusions.

What is IRS tax form 1116?
Form 1116 is the IRS 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.
Definition box: Form 1116 is the IRS form used to claim a credit for foreign income taxes paid or accrued.
What is Form 1116? It is the form that connects your foreign-source income, foreign taxes, US taxable income, and allowable credit. A common typo is Form 116 Foreign Tax Credit, but the correct form number is Form 1116.
Form 1116 separates 2 basic questions: what the form does and who files it.
| Purpose | Who files it |
|---|---|
| Calculates the foreign tax credit limitation and the allowable credit for a specific income category. | Individuals, estates, and trusts that paid or accrued certain foreign taxes to a foreign country or US territory. |
| Reports foreign income taxes paid or accrued in US dollars. | US citizens, resident aliens, green card holders, and certain nonresident aliens who meet limited IRS rules. |
| Summarizes credits from multiple Forms 1116 in Part IV. | Taxpayers with passive, general, foreign branch, section 951A, treaty-resourced, section 901(j), or lump-sum distribution categories. |
IRS Form 1116 applies to 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. The IRS Foreign Tax Credit Form 1116 matters because it helps prevent the same foreign-source income from being taxed twice.
When is Form 1116 required?
Form 1116 is required for most 2025 foreign tax credit claims unless the narrow election to claim the credit without Form 1116 applies. The simplified election is limited to passive foreign income, qualified payee statements, and total creditable foreign taxes of $300 or less, or $600 or less on a joint return.
When is Form 1116 required? You usually file it when you paid foreign income tax on wages, self-employment income, rental income, or income from multiple categories. The Form 1116 requirements also apply when you have carryovers, carrybacks, foreign tax redeterminations, or taxes above the $300/$600 exception.
- 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, or Schedule K-3.
- You have foreign tax credit carryovers, carrybacks, or foreign tax redeterminations.
The following 4 conditions may mean Form 1116 not required for the year:
- 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
The following 4 yes/no steps help you self-screen before filing:
-
Did you pay or accrue foreign income taxes in 2025?
If no, Form 1116 usually does not apply. If yes, continue. -
Are your total creditable foreign taxes $300 or less, or $600 or less on a joint return?
If no, you usually need Form 1116. If yes, continue. -
Was all foreign-source gross income passive category income reported on qualified payee statements?
If no, you usually need Form 1116. If yes, continue. -
Are you electing the simplified claim on Schedule 3?
If yes, you may skip Form 1116. If no, file Form 1116.
For the filing threshold context, see our guide to minimum income to file taxes in 2026.
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 per qualifying person.
Both tools reduce double taxation, but they work differently. 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.
The better choice depends on tax rate, income type, carryovers, and whether excluded income would affect other tax benefits.
| Factor | Form 1116 foreign tax credit | Form 2555 foreign earned income exclusion |
|---|---|---|
| Eligibility | Foreign-source income taxed by both the US and a foreign country, with creditable foreign taxes paid or accrued. | Foreign earned income, tax home abroad, and either bona fide residence or 330 full days abroad in a 12-month period. |
| Tax outcome | Reduces US income tax dollar-for-dollar, subject to the limitation. | Removes up to $130,000 of 2025 foreign earned income from US taxable income. |
| Income types | Earned income and passive income, if creditable taxes apply. | Earned income only, such as wages or self-employment income. |
| Carryovers | Unused credits may carry back 1 year and forward 10 years, by category. | No unused exclusion carryover. |
| IRA implications | May preserve more taxable compensation for IRA eligibility because income is not excluded. | Excluded earned income generally does not count as taxable compensation for IRA contribution purposes. |
| When better | Often stronger in high-tax countries, mixed-income cases, and family credit situations. | Often stronger in low-tax or no-tax countries when foreign tax credits are limited or unavailable. |
Which is better for expats? In a high-tax country such as Germany, France, or Japan, Form 1116 often produces a stronger result because foreign taxes may offset US tax. In a no-tax or low-tax country, Form 2555 may be more useful because there may be little or no foreign income tax to credit.
Families with qualifying children often need a careful comparison. Using Form 2555 can reduce taxable earned income and may affect refundable credit outcomes, while the foreign tax credit may preserve more income in the US calculation.
Read our full foreign earned income exclusion guide for eligibility details. The next step is confirming who can claim the credit and which taxes count.
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. For 2025 returns, the tax must meet 4 IRS tests before it is creditable.
Who is required to file Form 1116? A taxpayer who wants the foreign tax credit usually files Form 1116 unless the $300/$600 passive-income exception applies. These Form 1116 filing requirements apply separately from the broader question of whether you must file a Form 1040.
The following 4 taxpayer groups should check Form 1116 eligibility:
- US citizens: US citizens report worldwide income and may claim credits for qualified foreign income taxes on foreign-source income.
- Resident aliens: Resident aliens generally follow the same foreign tax credit rules as US citizens.
- Green card holders: Green card holders are usually resident aliens for US tax purposes and generally report worldwide income.
- Certain nonresident aliens: Nonresident aliens generally cannot claim the credit, except in limited cases such as being a resident of Puerto Rico for the full tax year or paying foreign tax on foreign-source income effectively connected with a US trade or business.
The foreign tax credit requires both the right taxpayer and the right type of tax.
| Requirement | Qualifies | Does not qualify | Example |
|---|---|---|---|
| Tax imposed on you | Wage withholding shown on a foreign payroll certificate | Tax paid by another person that is not legally your liability | French income tax withheld from your salary |
| Tax paid or accrued | Tax actually paid in 2025 or properly accrued under your method | Contested tax before the liability is resolved, unless special provisional credit rules apply | UK PAYE withholding paid during 2025 |
| Legal and actual liability | Final foreign income tax assessed under local law | Refundable subsidy or tax returned to you | German income tax assessed on a resident return |
| Income tax or tax in lieu of income tax | Net income tax or certain withholding tax replacing income tax | VAT, sales tax, property tax, or non-creditable social security tax | Canadian income tax can qualify; VAT does not |
NOTE! Not all foreign levies count as creditable taxes. A foreign tax must generally be an income tax or a tax in lieu of income tax, and gross-receipts-type taxes do not automatically qualify.
What qualifies and what does not qualify for the foreign tax credit
A foreign tax generally qualifies for the foreign tax credit 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. These 4 tests screen out common non-income taxes before you complete Form 1116.
This section helps you self-check before claiming the credit. For a broader overview, see our guide to the foreign tax credit for US expats.
The FTC usually covers foreign income taxes, not consumption, property, or penalty charges.
| Qualifies | Does not qualify |
|---|---|
| National foreign income tax | VAT or GST |
| Provincial, cantonal, or local income tax | Sales tax |
| Foreign withholding tax on dividends, interest, or royalties when creditable | Property tax |
| Tax in lieu of income tax that meets IRS rules | Interest or penalties paid to a foreign tax authority |
| Certain taxes paid to US territories treated as foreign taxes for FTC purposes | Social security taxes paid to a country covered by a US totalization agreement |
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.
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 so you do not try to credit non-income taxes.
How to calculate the foreign tax credit
The Form 1116 calculation compares 2 numbers: your creditable foreign taxes available for the category and the US tax limit assigned to that foreign-source taxable income. The allowable credit is generally the smaller of those 2 amounts.
The Form 1116 foreign tax credit calculation is not just foreign tax paid divided by worldwide income. The Form 1116 foreign tax credit instructions require income categories, deductions, foreign-source taxable income, worldwide taxable income, and US tax before the final limitation is applied.
- Step 1 – Convert to US dollars: Report amounts in US dollars. Taxes paid are generally translated using the exchange rate on the date paid or withheld, while accrued taxes may use the average rate if IRS conditions are met.
- Step 2 – Separate income by category: Use a separate Form 1116 for each income category, such as passive or general category income.
- Step 3 – Apply the limitation: Divide category foreign-source taxable income by worldwide taxable income, then multiply by the US tax amount used on line 20.
- Step 4 – Compare tax paid with the limit: Claim the smaller amount as the credit for that category.
Based on our client scenario at TFX: 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.
The following 3-line formula panel shows the result:
- Input: $50,000 foreign-source taxable income ÷ $100,000 worldwide taxable income = 50%.
- Calculation: 50% × $12,000 US tax = $6,000 maximum credit.
- Result: If Spain withheld $8,000 of creditable income tax, the current-year general category credit is capped at $6,000, with $2,000 potentially treated as excess foreign tax subject to carryover rules.
For unused credits, see our foreign tax credit carryover guide. 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. Wages usually fall in the general category, dividends and interest usually fall in the passive category, and specialized categories apply to GILTI, foreign branches, treaty-resourced income, sanctioned-country income, and lump-sum distributions.
The IRS category checked above Part I controls the income, deductions, tax, and limitation on that form. Mixing categories can distort the limitation and create an incorrect credit.
Each category has its own Form 1116 calculation and its own credit limitation.
| FTC income basket | Common expat example | Separate Form 1116 needed? |
|---|---|---|
| Passive category income | Foreign dividends, interest, rents, royalties, annuities, and many foreign investment gains | Yes |
| General category income | Foreign wages, salaries, self-employment income, and active business income | Yes |
| Section 951A category income | GILTI for US shareholders of certain controlled foreign corporations | Yes |
| Foreign branch category income | Business profits attributable to a qualified business unit in a foreign country | Yes |
| Section 901(j) income | Income from sanctioned countries, with special credit restrictions | Yes |
| Certain income re-sourced by treaty | Income treated as foreign-source under a treaty | Yes |
| Lump-sum distributions | Certain foreign pension or retirement lump-sum payments | Yes |
NOTE! Misclassifying income can reduce, delay, or invalidate the credit. Form 1116 passive income should not be combined with general wages just because both amounts came from the same country.
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. For 2025 Form 1116, line 19 divides line 17 by line 18, and line 20 supplies the US tax figure.
Displayed formula:
Foreign tax credit limit = (foreign-source taxable income in the category ÷ worldwide taxable income) × US tax against which the credit is allowed
The following 3 variables drive the limitation:
- Foreign-source taxable income in the category: The 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 such as the new senior deduction rule where applicable.
- US tax against which the credit is allowed: for individuals, line 20 generally starts with Form 1040 line 16 plus Schedule 2, line 12, with any required adjustments under 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.
Based on our client scenario at TFX: 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.
The following 4 calculation steps show the cap:
- 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.
What this means in practice: 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.
For related income-based terminology, see our guide to modified adjusted gross income.
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, so line 10 is left blank for that category.
Excess foreign tax is created when creditable foreign taxes available for a category exceed the Form 1116 limitation for that category. The carryover schedule preserves that excess for years when the same category has enough limitation to use it.
The following 4 timeline points explain the carryover flow:
- 2024: Prior-year unused credit may be carried into 2025 if it is still within the allowed period and the same category.
- 2025: Current-year excess foreign tax is calculated on Form 1116 after the limitation.
- 2024 carryback: Current-year excess is generally carried back 1 year first.
- 2026–2035 carryforward: Any remaining unused amount may carry forward up to 10 years.
The following 3 recordkeeping items should be tracked each year:
- Category of income, such as passive or general.
- Year the excess credit arose.
- Amount used, carried back, carried forward, or expired.
Schedule B (Form 1116) reconciles foreign tax carryovers by category. The shorthand Form 1116 Sch B usually refers to Schedule B (Form 1116), not Schedule B (Form 1040), which reports interest, dividends, and foreign account questions.
Many expats fail to understand how relevant document retention is, which is why we cover it in the TFX guide on how long to preserve tax and financial records.
Form 1116 foreign tax credit example
This Form 1116 foreign tax credit example uses 2 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 2 Forms 1116 and summarizes the allowed credits in Part IV.
Based on our client scenario at TFX: 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.
This sample Form 1116 uses 2 baskets because wages and dividends cannot be combined on one Form 1116.
| Example item | Passive category | General category |
|---|---|---|
| Foreign-source income | $2,000 dividends | $78,000 wages |
| Foreign tax paid | $300 withholding | $16,000 wage tax |
| Worldwide taxable income | $90,000 | $90,000 |
| US tax for limitation | $13,500 | $13,500 |
| Maximum credit | $300 | $11,700 |
| Allowed credit | $300 | $11,700 |
| Excess foreign tax | $0 | $4,300 |
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.
#1 – Passive category: dividends on 1099-DIV
The passive category example uses $2,000 of foreign dividends and $300 of foreign tax withheld. In this simplified 2025 case, the limitation equals $300, so the taxpayer can claim the full passive category credit before any required qualified dividend, capital gain, or deduction adjustments.
Foreign dividends are usually passive category income, but Form 1116 may require deduction allocation and special adjustments for qualified dividends or capital gain rate differentials. If foreign tax on passive income is reported in US dollars on Form 1099-DIV or a similar statement, the IRS says the amount does not need to be converted into foreign currency.
The passive category credit is allowed only up to the smaller of the foreign tax paid or the category limitation.
| Input | Amount | Result |
|---|---|---|
| Category checked | Passive category income | Separate passive Form 1116 |
| Foreign dividends | $2,000 | Part I foreign gross income |
| Related deductions | $0 in this simplified example | Actual returns may require allocations |
| Net foreign-source taxable income | $2,000 | Used in limitation |
| Worldwide taxable income | $90,000 | Limitation denominator |
| US tax before credits | $13,500 | Limitation multiplier |
| Limitation | $2,000 ÷ $90,000 × $13,500 = $300 | Maximum passive credit |
| Foreign tax withheld | $300 | Full $300 allowed |
Based on our client scenario at TFX: The passive limitation is $300, and the dividend tax withheld is also $300, so the current-year passive category credit is $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 better understand the dividend reporting context, read our guide to Form 1099-DIV for taxpayers with dividends.
#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. Because the Form 1116 limitation is $11,700, only $11,700 is allowed as the 2025 current-year general category credit.
Foreign wages usually fall into the general category because they come from personal services performed abroad. Pub. 54 states that earned income is sourced where the services are performed, regardless of whether salary is paid by a US employer or deposited into a US bank account.
The wage example shows why the correct basket matters: excess general category tax cannot automatically offset passive income.
| Input | Amount | Result |
|---|---|---|
| Category checked | General category income | Separate general Form 1116 |
| Foreign wages | $78,000 | Part I foreign-source income |
| Foreign income tax paid | $16,000 | Part II foreign taxes paid or accrued |
| Worldwide taxable income | $90,000 | Used on limitation line |
| US tax before credits | $13,500 | Used for line 20 calculation |
| Limitation | $78,000 ÷ $90,000 × $13,500 = $11,700 | Maximum general credit |
| Allowed credit | $11,700 | Current-year general category credit |
| Excess foreign tax | $4,300 | Potential carryback/carryforward |
Based on our client scenario at TFX: 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 Form 1116 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, and for 2025, it must be completed even when only 1 Form 1116 is filed. The final credit on Form 1116 line 35 carries to Schedule 3 (Form 1040), line 1, if Form 1116 is required.
The filing map shows where each number moves before the credit reaches Form 1040.
| Form line | What goes here |
|---|---|
| Form 1116, Part I | Foreign-source taxable income and related deductions for the checked category |
| Form 1116, Part II | Foreign taxes paid or accrued by country |
| Form 1116, Part III, lines 15–24 | Limitation calculation and allowable category credit |
| Form 1116, Part IV, lines 25–32 | Summary of credits from separate Forms 1116 |
| Form 1116, line 35 | Total foreign tax credit after any reduction |
| Schedule 3 (Form 1040), line 1 | Foreign tax credit reported on the individual return |
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 rule 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 treated as income in another category rather than remaining passive.
The existing article incorrectly framed this as optional. The IRS instructions state that passive category income does not include high-taxed income, and the reclassified amount is reported with “HTKO” entries on both the passive Form 1116 and the other category form.
It matters because:
- It can move income and taxes out of the passive basket.
- It can change the limitation calculation for more than 1 Form 1116.
- It can affect whether excess foreign taxes are trapped in a category.
Based on our client scenario at TFX: A US expat has a passive foreign interest taxed at a high foreign rate after expense allocation. The income may need to be removed from the passive Form 1116 with an HTKO entry and added to the other applicable category, changing both category limits.
Caution Note: 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.
Understanding the structure of Form 1116
Form 1116 is built around 4 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 the taxpayer files only 1 Form 1116.
Each Form 1116 applies to only 1 income category checked above Part I. If a taxpayer has both foreign wages and foreign dividends, the return generally includes 2 Forms 1116 plus 1 summary Part IV.
The form structure follows income first, tax second, limitation third, and summary last.
| Part | Purpose | Common document needed |
|---|---|---|
| Category checkbox above Part I | Identifies the income basket for that form | Income summary by category |
| Part I | Reports foreign-source taxable income or loss and allocable deductions | Payroll records, brokerage statements, Schedule K-3 |
| Part II | Reports foreign taxes paid or accrued by country | Foreign tax returns, pay slips, withholding certificates |
| Part III | Calculates the credit limitation and category credit | Form 1040, Schedule 1-A, Schedule 2, deduction schedules |
| Part IV | Summarizes separate category credits | Other Forms 1116 filed with the return |
| Schedule B (Form 1116) | Reconciles carryovers by category and year | Prior-year Forms 1116 and carryover records |
| Schedule C (Form 1116) | Reports foreign tax redeterminations | Foreign tax refund, audit, amended assessment, or adjustment notice |
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.
Step-by-step guide to filing Form 1116
To file Form 1116 for a 2025 return, gather foreign tax records, separate income by category, convert amounts to US dollars, calculate the limitation, and enter the final credit on Schedule 3. The 2025 Form 1116 instructions should be checked before filing because Part IV has changed for the year.
NOTE! Use the current IRS Form 1116 instructions before entering numbers on the form. For example, supporting documents may include foreign tax assessments, foreign wage slips, brokerage statements showing foreign tax withheld, Form 1099-DIV, Schedule K-3, foreign tax payment receipts, and exchange-rate records.
How to fill out Form 1116: Start with the income category, then complete income, deductions, foreign taxes, the limitation, and the summary. Part II columns A, B, and C are country columns, not wage, dividend, and interest columns.
The following 5 items should be ready before you file:
- Foreign tax returns or assessments.
- Foreign wage statements, pension slips, or self-employment records.
- Brokerage statements, Form 1099-DIV, Form 1099-INT, Schedule K-1, or Schedule K-3.
- Proof of foreign tax paid, withheld, refunded, or accrued.
- Exchange-rate support for each conversion method used.
The following 6 filing steps keep the form in order:
- Choose the income category. Use a separate Form 1116 for each category.
- Enter foreign-source income in Part I. Include only income in the category checked above Part I.
- Allocate deductions. Include direct expenses and required allocations, including standard deduction or itemized deduction allocation when applicable.
- Report foreign taxes in Part II. Use columns for each country or territory, and report paid or accrued taxes as required.
- Calculate the limitation in Part III. Use line 17, line 18, line 19, line 20, and line 24 to determine the allowed category credit.
- Summarize the credit in Part IV. Complete Part IV on the proper Form 1116 and carry the final credit to Schedule 3.
The following 5 lines should be double-checked 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.

Form 1116 checklist before you file
A short pre-filing checklist can prevent the 5 most common Form 1116 errors: wrong basket, wrong tax type, missing US-dollar conversion support, carryover mismatch, and missing source documents. Use it before submitting a 2025 return in 2026.
The following 8 yes/no checks help confirm the return is ready, so mentally check the boxes, as you read through:
☐ Did I separate passive, general, and other categories into separate Forms 1116?
☐ Did I confirm the foreign levy is an income tax or a tax in lieu of income tax?
☐ Did I exclude VAT, sales tax, property tax, interest, and penalties from the credit?
☐ Did I reduce foreign taxes for any income excluded on Form 2555?
☐ Did I convert foreign tax paid using the correct payment-date or withholding-date exchange rate, unless an exception applies?
☐ Did I attach Schedule B (Form 1116) if I used or generated carryovers?
☐ Did I attach or retain proof of foreign tax paid, withheld, accrued, refunded, or reassessed?
☐ Did I confirm Form 1116 line 35 matches Schedule 3 line 1?
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. The IRS specifically requires a detailed explanation for foreign currency conversion and a statement for certain foreign tax changes.
The following 5 situations 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 one-sentence 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; the IRS says Form 8275 is used to disclose items or positions that are not adequately disclosed on a return to avoid certain penalties.
See our updated Form 8275 disclosure guide for a separate discussion of disclosure statements.
Common mistakes to avoid
The most common Form 1116 mistakes involve 9 filing issues: wrong category, wrong tax type, wrong exchange rate, missing carryovers, missing Schedule B, double-counted Form 2555 income, weak documentation, incorrect Part II country columns, and missing explanation statements. Several can change the credit or trigger IRS correspondence.
- Using the wrong basket. Passive income and general income usually need separate Forms 1116.
- Crediting non-income taxes. VAT, sales tax, property tax, and penalties do not qualify as foreign income taxes.
- Using one yearly average rate for all taxes paid. Taxes paid are generally translated at the payment or withholding date unless an exception applies.
- Forgetting Form 2555 reductions. You cannot claim a credit for foreign taxes allocable to excluded income.
- Treating country columns as income-type columns. Form 1116 Part II columns are country or territory columns.
- Skipping Schedule B (Form 1116). Schedule B is needed if you enter a carryover from a prior year or generate a current-year carryover, unless an instruction exception applies.
- Not tracking carryovers by category. Passive carryovers cannot freely offset general category income.
- Ignoring foreign tax refunds or reassessments. Schedule C (Form 1116) may be required for foreign tax redeterminations.
- Filing without a statement when the numbers need context. Currency conversions, amended foreign taxes, and unusual allocations may need a short explanation.

Filing Form 1116 feels overwhelming?
Form 1116 can involve 2 or more forms, multiple currencies, and category-by-category carryovers when you have wages, investments, and foreign tax refunds in the same year. TFX helps US expats organize the numbers and file with fewer surprises.
If your return includes foreign wages, dividends, carryovers, or Form 2555 decisions, a second look can prevent expensive mistakes.
FAQ
You do not always have to file Form 1116. For 2025 returns, you may skip it only if all foreign-source gross income is passive category income, the income and taxes are reported on qualified payee statements, and total creditable foreign taxes are $300 or less, or $600 or less on a joint return.
Yes, but not on the same income. You cannot claim the foreign tax credit for taxes allocable to income excluded on Form 2555, and the IRS requires taxes to be reduced when only part of foreign earned income is excluded.
A foreign tax generally qualifies if it is imposed on you, paid or accrued by you, legally owed, and an income tax or a tax in lieu of income tax. The IRS lists 4 tests for qualified foreign taxes.
Yes, in most cases. Wages are usually general category income, while dividends are usually passive category income, and the IRS generally requires a separate Form 1116 for each category.
The excess may be carried back 1 year and forward 10 years, subject to category-by-category rules and exceptions. No carrybacks or carryovers are allowed for section 951A category income.
For 2025 returns, Form 1116 line 35 carries the foreign tax credit to Schedule 3 (Form 1040), line 1, when Form 1116 is required. Part IV summarizes separate category credits before the final number flows to Schedule 3.
