Foreign tax credit for US expats: Rules, limits, and how to claim it
The US foreign tax credit is a nonrefundable credit that reduces your US tax bill by the amount of qualifying income tax you paid or accrued to a foreign government on foreign-source income also subject to US tax.
It is calculated on Form 1116 for most filers – though small amounts may qualify for a simpler path.
The FTC can reduce your US tax to zero, but not below zero. Any unused credit generally carries back one year and forward ten years under IRC section 904(c), except for section 951A category taxes, which have no carryback or carryforward.
Quick answers:
- What is it? A nonrefundable credit that offsets US tax on income already taxed abroad – Pub. 514.
- Who can claim it? US citizens, resident aliens, and certain nonresident aliens. Pass-through beneficiaries, partners, S corp shareholders, and mutual fund shareholders may also qualify in limited cases.
- When do you need Form 1116? Almost always. You can skip it only if all foreign income is passive, taxes are $300 or less – $600 or less for joint filers – everything is on qualified payee statements, and all other IRS conditions are met.
- $300/$600 exception: When all conditions are met, skip Form 1116 and enter the credit directly on Schedule 3, line 1 of Form 1040.
- How the credit is capped: FTC limit = US tax before credits x foreign-source taxable income in the category / worldwide taxable income. You claim the lower of the actual foreign taxes or that limit.
How it works in one example
A single US expat in Germany earns $100,000 abroad and pays $25,000 in German tax. After the 2025 standard deduction, US tax before credits on that income is $13,449. The FTC limit is $13,449, so the expat claims $13,449 as a credit and carries the $11,551 excess forward.
The FTC is one of the most effective tools for preventing double taxation, but claiming it correctly requires matching foreign and US tax years and currencies precisely. Our CPAs and EAs handle these calculations every day.
What is the foreign tax credit?
The foreign tax credit reduces the US income tax you owe by the amount of income tax you paid or accrued to a foreign government on income also subject to US tax – Pub. 514.
The credit is nonrefundable – it is the government’s main mechanism for preventing the same income from being taxed twice.
The credit does not generate a standalone refund. It can only reduce your US tax to zero – nothing more.
TFX client scenario
Josh, single, lives in Germany and receives a $1,000 dividend. German withholding is $150, shown on a Form 1099-DIV.
Because the amount is under $300, all passive, and reported on a payee statement, Josh claims the $150 directly on Schedule 3 – no Form 1116 required. His US tax drops by $150, but if his US liability were already zero, he would receive no refund.
Credit vs deduction
If you itemize, you can deduct eligible foreign income taxes on Schedule A instead of claiming the credit. In most cases, the credit is more valuable – calculate both ways and use the result that lowers your total tax the most.
Our FTC vs. deduction comparison walks through side-by-side examples.
The FTC is not limited to current-year returns. Expats catching up on multiple past-due years under the IRS streamlined foreign offshore procedures can still claim the credit on each delinquent return, which can reduce or eliminate the US tax owed on each catch-up filing.
Foreign tax credit eligibility: Who can claim it?
US citizens and resident aliens can generally claim the credit, as can nonresident aliens and pass-through filers in limited cases. The foreign tax itself must also pass a separate set of tests before any credit applies.
Foreign tax credit requirements for US taxpayers abroad
The following four requirements must all be satisfied per Pub. 514:
- Taxpayer status. You are a US citizen, a resident alien, or, in limited cases, an estate or trust that faces tax on the same income in both countries.
- Foreign-source income. The income is foreign-source and also taxable under US law. Income excluded under the Foreign Earned Income Exclusion does not qualify. US-source income generally does not enter the FTC calculation, but income re-sourced under an applicable tax treaty may qualify if you elect that treatment using a separate Form 1116, and where required, Form 8833.
- Qualifying tax. The foreign tax is a legal and actual obligation paid or accrued to a foreign government, and it qualifies as an income tax – or a tax in lieu of an income tax under IRC section 903.
- Credit or deduction, not both. You choose each year between claiming the credit or deducting eligible foreign taxes on Schedule A. Both cannot apply to the same payment.
Most individuals calculate the credit on Form 1116 and report it on Schedule 3 of Form 1040.
Small amounts of qualified passive tax – up to $300 for single filers or $600 for joint filers – can be claimed directly without Form 1116 when reported on a payee statement and all other IRS conditions are met.
What foreign taxes qualify for the foreign tax credit?
A qualifying levy must be either an income tax imposed on net income or a tax imposed in lieu of an income tax under IRC section 903. The following five income types and related taxes commonly qualify:
- Wages – generally sourced where the services are performed. Self-employment income is sourced under the facts and circumstances, and in many cases on a time basis.
- Interest – generally sourced by the residence of the payer. Interest from a foreign payer is often foreign-source – when it qualifies, it is reported on your US return and may be creditable.
- Dividends – from foreign corporations, when the tax imposed by the foreign country meets the creditability tests under IRC sections 901 and 903. The dividend must be foreign-source under US rules.
- Royalties – from intellectual property used outside the US, taxed under local law, and generally foreign-source.
- Foreign branch profits – reported in the correct Form 1116 category.
Foreign tax credit checklist
Use this pre-filing checklist before claiming the credit. Each item should be confirmed:
- Taxpayer status confirmed. You are a US citizen, resident alien, or qualifying nonresident alien, estate, or trust.
- Foreign taxes are qualifying. The tax is a compulsory income tax, or a tax in lieu of one, imposed by a foreign government – not VAT, social security, or a property tax.
- Income source verified. The income is foreign-source under US rules. US-source income generally does not qualify, except under treaty re-sourcing.
- Paid or accrued method chosen. Cash-method filers claim in the year paid. If you elected the accrual basis on a prior timely filed original return, that election applies to all later years.
- No FEIE overlap. Income excluded under Form 2555 is removed from the FTC calculation entirely, along with the foreign taxes allocable to that excluded income.
- Records gathered. Payee statements, foreign tax receipts, exchange-rate documentation, and Schedule B from prior Form 1116 filings are on hand.
- Income categories identified. Each item of income is assigned to the correct Form 1116 category – passive, general, foreign branch, section 951A, treaty-resourced, or other.
Our tax documents checklist has a broader list of records US expats should keep.
What taxes do not qualify for the FTC?
Some foreign taxes do not qualify – they are not based on income, or they buy a specific benefit from the foreign government. A levy not imposed on net income may still qualify as a tax in lieu of an income tax under IRC section 903 if it meets the applicable requirements.
The taxes below generally do not pass either test.
Taxes that are not creditable under IRC sections 901 and 903:
| Tax type | Why it does not qualify |
|---|---|
| Value-added tax or GST | Consumption tax, not an income tax |
| Sales or gross receipts tax | Based on turnover, not net realized income |
| Real property or wealth taxes | Based on assets, not income |
| Social security or payroll contributions | Not an income tax under IRC sections 901 and 903 |
| Penalties, interest, and similar charges | Not a tax for credit purposes |
| Taxes for a specific economic benefit | Treated as payment for a benefit, not a creditable tax |
| Taxes on income from sanctioned countries – IRC section 901(j) | Credit generally barred for taxes paid to the sanctioned country itself, but taxes paid to a third country on the same income may still qualify |
Keeping these items off your Form 1116 helps avoid amended filings and foreign tax redetermination issues later.
How the FTC works in the US
The federal foreign tax credit reduces your US tax bill only on income that is also taxed abroad. It does not offset tax on US-source income, and the amount you can claim is always capped by a formula calculated separately for each income category.
Foreign source income for foreign tax credit purposes
For FTC purposes, foreign source income includes amounts that US sourcing rules treat as earned or arising outside the United States. Only this income enters the foreign tax credit limit calculation.
Sourcing rules by income type:
- Wages – sourced where the services are performed.
- Interest – generally sourced by the payer’s residence.
- Dividends – sourced based on whether the paying corporation is US or foreign, subject to limited exceptions.
- Royalties – sourced where the intellectual property is used.
If the same item of income is foreign-source under US rules and taxed abroad, it can generate a credit. US-source income generally cannot – but income that is US-source under normal rules may be treated as foreign-source under an applicable treaty if you elect that treatment, using a separate Form 1116 for the treaty-resourced category. Form 8833 may also be required.
The sourcing details that feed the FTC calculation are covered in our foreign income reporting guide, including how each income type maps to the correct Form 1040 line.
Foreign tax credit computation: How the limit is calculated
The foreign tax credit limitation caps the credit at the US tax attributable to your foreign-source income in each category, using this formula – Pub. 514:
FTC limit = US tax before credits x foreign-source taxable income in the category / worldwide taxable income
The credit you can claim is the lower of the actual foreign taxes paid and the FTC limit for that category. Any excess carries over.
2025 filing note: The new senior deduction under section 151(d)(5)(C) – up to $6,000 per qualifying taxpayer aged 65 or older – must be added back to worldwide taxable income when figuring the limit. The Form 1116 instructions for 2025 include this add-back in the denominator calculation.
Carryover rules:
- Excess foreign taxes generally carry back one year and forward ten years in the same category.
- Taxes claimed under the no-Form-1116 election cannot be carried to or from that year.
- Section 951A category taxes do not carry over at all.
Worked examples:
| Example A | Example B | Example C | |
|---|---|---|---|
| Foreign taxes paid | $8,000 | $14,000 | $3,000 |
| US tax before credits | $10,000 | $10,000 | $10,000 |
| FTC limit – all income foreign-source | $10,000 | $10,000 | $10,000 |
| Allowable credit | $8,000 | $10,000 | $3,000 |
| Excess carried forward | $0 | $4,000 | $0 |
In Example B, the $4,000 excess in foreign taxes is not lost – it generally carries back one year or forward up to ten years, except for section 951A category taxes.
Foreign tax credit example: Step-by-step calculation
This foreign tax credit example walks through the formula line by line.
Facts: Sarah, a US citizen in France, earns $120,000 in foreign wages for tax year 2025 and pays $30,000 in French income tax. She has no US-source income. Her US tax before credits is $17,867.
| Step | Input | Value |
|---|---|---|
| 1. Foreign-source taxable income – general category | Wages | $120,000 |
| 2. Worldwide taxable income | After standard deduction of $15,750 (2025) | $104,250 |
| 3. US tax before credits | From the 2025 tax rate schedule | $17,867 |
| 4. FTC limit | $17,867 x $104,250 / $104,250 | $17,867 |
| 5. Foreign taxes paid | French income tax | $30,000 |
| 6. Allowable credit | Lesser of $30,000 or $17,867 | $17,867 |
| 7. US tax after credit | $17,867 – $17,867 | $0 |
| 8. Excess credit carried forward | $30,000 – $17,867 | $12,133 |
Sarah owes zero US tax for 2025. The $12,133 excess can be carried back to 2024 or forward to any year through 2035, tracked on Schedule B of Form 1116.
What is the foreign tax credit maximum you can claim?
There is no flat dollar ceiling. The maximum foreign tax credit in any category will never exceed your actual US tax attributable to that category of income.
The foreign tax credit limit is always capped by the formula, not by a fixed number. Two expats earning the same foreign income can end up with very different allowable credits depending on their overall income mix and deductions.
Can you claim a foreign tax credit on US source income?
The credit generally does not apply to US-source income. The FTC exists to prevent double taxation of the same income by two countries – if income is US-source under US rules, no FTC applies even if a foreign country also taxes it under its own domestic law.
The exception: treaty re-sourcing
If an applicable income tax treaty treats certain US-source income as foreign-source, and you make the required election, that income enters its own separate Form 1116 category – “certain income re-sourced by treaty.” You may also need to file Form 8833 to disclose the treaty position.
Foreign tax credit carryback and carryover rules
When foreign taxes exceed the US limit for a given year, the unused credit does not disappear. It can be applied to other tax years using carryback and carryforward rules under IRC section 904(c).
Three rules govern how unused FTC balances are handled:
- Carry back unused credits to the immediately preceding tax year – one year back only.
- Carry forward any remaining balance for up to ten future tax years. Section 951A category taxes are excluded from this rule and cannot be carried back or forward.
- Track each category separately on Schedule B of Form 1116 – passive and general category credits cannot be mixed or transferred between baskets.
TFX client scenario
A TFX client paid $12,000 in UK taxes for tax year 2024 but had only a $9,000 US FTC limit that year. The $3,000 excess can be carried back to the 2023 return by amendment, or carried forward to any year through 2034.
If a foreign tax is later refunded or reassessed, report the change as a foreign tax redetermination on Schedule C of Form 1116.
Our foreign tax credit carryover guide has a detailed walkthrough of tracking and using excess credits.
How to claim the foreign tax credit
The key threshold is simple: if your qualified foreign taxes are $300 or less for single filers, or $600 or less for joint filers, and all income is passive and reported on a payee statement, you can skip Form 1116 entirely. Everyone else files Form 1116, one per income category.
When you can claim the FTC without Form 1116
The de minimis election – sometimes called the Form 1116 exemption – applies when all of the following conditions are met per the Form 1116 instructions:
- All foreign income is in the passive category – dividends, interest, or similar.
- Qualified foreign taxes total $300 or less if single, or $600 or less if married filing jointly.
- All income and taxes appear on a qualified payee statement – Form 1099-DIV, 1099-INT, Schedule K-1 or K-3, or similar.
Estates and trusts are not eligible for this election.
When all conditions are met, enter the credit directly on Schedule 3, line 1 of Form 1040. This is the most common path for passive income like dividends and interest where the withheld amounts are small.
One trade-off: taxes claimed under this election cannot be carried to or from that year. If you expect to have excess credits worth carrying forward, filing Form 1116 may be the better choice even when you qualify for the shortcut.
How to claim foreign tax credit with Form 1116
Most expats file Form 1116 to claim the foreign tax credit – one form per income category. The form calculates the FTC limit for each basket, tracks carryovers on Schedule B, and reports the final credit on Schedule 3 of Form 1040.
You need a separate Form 1116 for each category of income – passive, general, foreign branch, and so on. Credits from one basket cannot offset a shortfall in another.
Foreign tax credit and Form 1116 line-by-line guide
Form 1116 has four main parts. Each part handles a specific piece of the foreign tax credit limitation calculation.
Part I – Taxable income or loss from sources outside the US
Enter gross income from foreign sources in the applicable category, then subtract related deductions. The result is your foreign-source taxable income for this basket.
Part II – Foreign taxes paid or accrued
List each foreign country, the date taxes were paid or accrued, the amounts in foreign currency, and the US dollar conversion. Cash-basis filers use the exchange rate on the date paid. Filers who elected the accrual method generally use the average exchange rate for the foreign tax year.
Part III – Figuring the credit
This is where the limit formula runs. Line 19 divides your foreign-source taxable income by worldwide taxable income, and line 21 multiplies that ratio by your US tax before credits to produce the limit. Your allowable credit is the lesser of the tax paid from Part II or the limit from Part III.
Part IV – Summary of credits from separate parts III
If you filed multiple Forms 1116 for different baskets, Part IV totals the credits across all categories. The final number flows to Schedule 3 of Form 1040.
Common mistakes in Form 1116:
- Mixing income categories on one form
- Using the wrong exchange rate
- Forgetting to remove FEIE-excluded income from Part I
How do I claim a foreign tax credit on a tax return?
The following nine steps cover the complete process for filing with Form 1116:
- Decide: credit or deduction. Deducting foreign taxes on Schedule A is an alternative if you itemize. Calculate both ways – the credit is more valuable in most cases.
- Check the de minimis exception. If qualified foreign taxes are $300 or less for single filers, or $600 or less for joint filers, all passive, and on payee statements, claim directly on Schedule 3.
- Choose the paid or accrued method. Cash-method filers claim the credit in the year foreign taxes are paid. If you elect the accrual basis on a timely filed original return, that election applies to all foreign taxes and must be followed in all later years.
- Gather documentation. Collect payee statements – Forms 1099-DIV, 1099-INT – foreign tax receipts, and local tax assessments showing dates, amounts, and tax type.
- Sort income by category. Identify whether each item is passive, general, foreign branch, section 951A, treaty-resourced, section 901(j), or lump-sum. Each category requires its own Form 1116.
- Calculate the FTC limit. Apply the formula per category. Take the lower of the limit and actual taxes paid – that is your allowable credit.
- Handle carryovers. If taxes exceed the limit, carry back one year and carry forward up to ten years. Track balances on Schedule B of Form 1116.
- Coordinate with FEIE. Income excluded under Form 2555 cannot generate an FTC. Remove excluded income and its related foreign taxes from the calculation entirely. When wages are only partly excluded, the disallowance is proportional.
- Report redeterminations. If a foreign tax is later refunded, reassessed, or contested, report it on Schedule C of Form 1116. For contested taxes still in dispute, file Form 7204 to make a provisional FTC election while the dispute is pending.
Calculating foreign tax credit: Paid vs. accrued method
Cash-method filers claim the credit in the year foreign taxes are paid. If you elect to claim the credit on an accrual basis, you make the election by checking the “Accrued” box in Part II of Form 1116 on a timely filed original return. You cannot make this election on an amended return.
Once you make that choice, it applies to all qualifying foreign taxes and must be followed in all later years – Pub. 514.
Exchange rate rules:
- Cash-basis filers – convert foreign currency at the exchange rate on the date paid.
- Accrual-basis filers – generally use the average exchange rate for the related foreign tax year, with exceptions for inflationary currencies.
- Documentation – keep exchange-rate records with your files. The IRS can request them if the return is examined.
What records do you need to claim FTC?
Keep the following records with your tax files. You generally do not attach them to Form 1040, 1040-SR, or 1040-NR unless specifically required:
- Payee statements – Forms 1099-DIV, 1099-INT, or foreign equivalents
- Foreign tax receipts or assessments showing tax type, amount, and date paid
- Currency conversion documentation – cash-basis filers use the rate on the date paid; accrual-basis filers generally use the average rate for the foreign tax year
- Schedule B of Form 1116 from prior years, showing carryover balances by category
The IRS can request FTC supporting documents for at least three years after filing – our records retention guide has the full timeline by document type.
FTC refund rules: Is the credit refundable?
The foreign tax credit is not refundable. It reduces your US tax bill dollar-for-dollar, but it stops at zero – any excess becomes a carryover, not a cash refund.
| Question | Answer |
|---|---|
| Can FTC produce a cash refund? | No – it reduces US tax to zero at most |
| What happens to excess credits? | They generally carry back one year and forward ten years, except section 951A category taxes, which have no carryback or carryover |
| Are carryovers ever paid out as cash? | No – they remain credits usable only against future US tax liability |
Unused credits stay inside their separate category basket, tracked on Schedule B of Form 1116. They are never converted into cash.
Is the foreign tax credit refundable?
No. If your US tax liability is already zero – for example, because the FEIE eliminated all taxable income – the credit has nothing to reduce and produces no refund.
Limit on foreign tax credit: What reduces your allowable amount?
There is no flat-dollar ceiling on the FTC. The allowable amount is determined by a formula calculated separately for each income category, so the credit never exceeds what the US would have taxed on the same foreign income.
The formula is the same one covered earlier: FTC limit = US tax before credits x foreign-source taxable income in the category / worldwide taxable income. What makes the foreign tax credit limitation complex is that it applies per basket – not to your total foreign taxes as a whole.
Common reasons your allowable FTC is reduced:
- FEIE interaction – income excluded under Form 2555 leaves the FTC fraction. When the numerator shrinks, so does the limit.
- The foreign-source-income ratio – the more US-source income you have relative to foreign-source income, the lower the limit.
- Separate baskets – excess credits in one category cannot offset US tax in another.
- Nonqualifying taxes – VAT, property taxes, and social contributions do not enter the calculation.
Foreign tax credit maximum by income category
Foreign tax credit limitations apply independently to every category on your return. The 2025 Form 1116 has seven separate income category checkboxes, each requiring its own form.
Each category is its own ceiling – credits in one basket cannot reduce tax in another.
| Income category | Common examples | Separate Form 1116? |
|---|---|---|
| Section 951A | CFC shareholders | Yes |
| Foreign branch | Profits from a qualified foreign branch | Yes |
| Passive | Dividends, interest, rents | Yes |
| General | Wages, business profits, self-employment | Yes |
| Section 901(j) – sanctioned countries | Income from sanctioned countries; foreign taxes paid to the sanctioned country itself are generally not creditable, but taxes paid to a third country on the same income may qualify | Yes |
| Treaty-resourced income | Income re-sourced under a tax treaty | Yes |
| Lump-sum distributions | Certain pension payouts | Yes |
Section 245A(d) applies only to corporations filing Form 1118 – it does not appear on the individual Form 1116.
Separate baskets and FTC rules
Each basket is entirely self-contained. Excess credits in the passive category cannot offset a shortfall in the general category, and vice versa.
Foreign tax credit limitations for each basket follow the same creditability tests under IRC sections 901 and 903, but the limit on foreign tax credit is always done independently per category. A high foreign tax rate in one basket cannot help you in another.
If most of your foreign income is passive – dividends, interest – your general category credit is zero by default, even if you paid significant general-category foreign taxes in a prior year.
Special foreign tax credit rules for dividends, withholding tax, IRA, and state taxes
The standard FTC rules cover most expat situations, but four common edge cases follow their own logic.
Foreign tax credit for dividends and mutual funds
Foreign withholding tax on dividends is generally creditable – provided the dividend is foreign-source, and the tax meets the creditability requirements under IRC section 901.
Mutual fund pass-through rule
When a regulated investment company pays foreign taxes on your behalf and reports them in box 7 of Form 1099-DIV, you may claim the credit without owning the foreign stock directly – Pub. 514.
Foreign dividends reported on Form 1040 follow specific reporting rules that determine how the credit flows through to Form 1116.
Withholding tax and foreign tax credit rules
Whether foreign withholding qualifies as a creditable income tax depends on more than the rate. The tax must be compulsory, legally owed, and meet the income-tax or in-lieu-of-tax requirements under IRC sections 901 and 903. A reduced treaty withholding rate alone does not establish creditability – the underlying levy must still pass these tests.
In practice, a flat withholding rate on dividends or interest – such as a 15% treaty rate on dividends – generally qualifies because it is imposed as a substitute for a net-income tax on the same income.
Foreign tax credit IRA questions: Does it apply?
Foreign taxes paid inside an IRA do not pass through to you as the account holder. If your IRA holds shares in a foreign mutual fund that reports foreign taxes on Form 1099-DIV, the FTC still does not flow through to you. In most cases, those taxes are lost from a credit standpoint.
Foreign taxes withheld inside other US retirement accounts held abroad follow the same rule – the account holder generally cannot claim the credit.
Foreign tax credit state taxes: What to know
The federal FTC only offsets federal income tax – it does not reduce your state tax liability.
Some states conform to the federal definition of taxable income but do not allow a state-level foreign tax credit. A handful offer their own credit or deduction for foreign taxes paid, but eligibility varies by state.
Foreign tax credit vs Foreign earned income exclusion
Both tools aim to prevent double taxation on foreign income. The right choice depends on income type, foreign tax rate, and how you file.
For most expats in high-tax countries, the FTC eliminates double taxation dollar-for-dollar. The FEIE – $130,000 for the 2025 tax year, $132,900 for the 2026 tax year – is generally better when foreign taxes are low or zero.
| What you need to know | Foreign tax credit | Foreign earned income exclusion |
|---|---|---|
| Purpose | Offsets US tax with creditable foreign income taxes paid or accrued | Removes a portion of foreign-earned income from US taxable income |
| 2025 tax year amount | No overall dollar cap; limited by formula per category | Maximum exclusion is $130,000 per qualifying person |
| 2026 tax year amount | No overall dollar cap; limited by formula per category | Maximum exclusion is $132,900 per qualifying person |
| How it reduces tax | Nonrefundable credit applied against US income tax | Exclusion lowers AGI; housing exclusion or deduction may apply |
| Where to claim | Form 1116; flows to Schedule 3, line 1 on Form 1040 | Form 2555 attached to the return |
| Who it suits | Taxpayers paying moderate to high foreign effective rates | Earned income abroad where foreign tax is low or zero |
| Income covered | Broad: wages, self-employment, interest, dividends, business profits | Narrow: earned income for services in a foreign country; investment income does not qualify |
| Interaction | No credit for income you exclude under FEIE; excluded income and its allocable foreign taxes are removed from the FTC calculation | Can claim FEIE on earned income and FTC on other income that remains taxable |
Our FTC vs FEIE comparison has detailed examples by income level and country.
Foreign tax credit vs deduction vs FEIE comparison table
The FTC, foreign tax deduction, and FEIE are the three main tools for reducing or eliminating double taxation on foreign income.
| Factor | Foreign tax credit | Foreign tax deduction | Foreign earned income exclusion |
|---|---|---|---|
| Tax benefit | Dollar-for-dollar US tax reduction | Reduces taxable income at your marginal rate | Removes up to $130,000 (2025) / $132,900 (2026) of earned income from US taxable income |
| Required form | Form 1116 | Schedule A, line 6 | Form 2555 |
| Requires itemizing? | No | Yes | No |
| Carryforward | 1 year back, 10 years forward, by category | None – unused benefit is permanently lost | N/A |
| Best for | Expats in moderate- to high-tax countries | Cases where FTC is fully limited, and itemizing is already chosen | Low- or zero-tax countries; earned income only |
| Can combine with others? | Yes – with FEIE on different income, or instead of the deduction | Cannot combine with FTC on the same taxes | Yes – with FTC on non-excluded income |
Rule of thumb: Start with the FTC if you pay meaningful foreign income taxes. Consider the FEIE if you are in a low-tax or no-tax country and your earned income is under the exclusion limit. The deduction is a fallback for situations where the credit is fully limited, and you are already itemizing.
Our FTC vs. deduction guide has a detailed comparison with worked examples.
Foreign tax credit vs. foreign tax deduction: Which is better?
For most filers, the credit wins. It cuts your US tax dollar-for-dollar, while a Schedule A deduction for foreign taxes only reduces taxable income at your marginal rate. Calculate both to confirm which works better for your situation. You cannot use both for the same foreign taxes in the same year.
| Foreign tax credit | Foreign tax deduction | |
|---|---|---|
| How it works | Reduces US tax dollar-for-dollar | Reduces taxable income at your marginal rate |
| Requires itemizing? | No | Yes – must itemize on Schedule A |
| Better when | Foreign taxes are high relative to the US rate | FTC is fully limited and itemizing produces a larger benefit |
| Switching: deduction to credit | Up to 10 years from the original return’s due date, by amended return | N/A |
| Switching: credit to deduction | Within 3 years from when you filed, or 2 years from when you paid the tax, whichever is later | N/A |
| AMT interaction | FTC is limited under AMT rules | Deduction may also be disallowed under AMT |
Why the switching windows are different
Taxpayers have 10 years to switch from a deduction to a credit. Going the other way – credit to deduction – must be done within 3 years from filing or 2 years from payment, whichever is later, per Pub. 514.
If your FTC is fully limited by the category formula and you are already itemizing, the deduction can preserve some tax benefit where the credit produces nothing.
Our complete FTC vs. deduction analysis walks through worked examples.
New foreign tax credit rules and 2025–2026 updates
For the 2025 tax year, the foreign tax credit framework remains largely stable for individual expats filing Form 1116. The $300/$600 de minimis thresholds, the basic limit formula, and the seven separate limitation categories are unchanged.
Temporary relief on creditability rules
Final FTC regulations published in January 2022 tightened the tests for whether a foreign tax qualifies as creditable. The IRS issued Notice 2023-55 in July 2023, letting taxpayers apply the prior rules in place of certain 2022 provisions.
Notice 2023-80, released in December 2023, extended that relief to partnerships and their partners and extended the relief period until further guidance is issued. As of October 2026, no further notice has replaced it – the relief remains in effect.
Section 960(d)(4) – new 10% disallowance
The One Big Beautiful Bill Act added section 960(d)(4), which disallows a credit for 10% of certain deemed-paid foreign taxes connected to section 951A-related distributions.
Per Notice 2025-77, the rule applies to foreign taxes on distributions of section 951A PTEP arising from inclusions in a US shareholder’s taxable year ending after June 28, 2025.
This change primarily affects CFC shareholders, not most individual expats filing Form 1116 on their own wages or investment income.
GILTI/NCTI credit percentage
P.L. 119-21 raised the deemed-paid credit percentage from 80% to 90% for tax years beginning after December 31, 2025. This change applies to corporations and individuals making a section 962 election.
Form 1116 for individuals and Form 1118 for deemed-paid credits under section 962 remain the current filing vehicles for this season.
The one-month deferral repeal under the OBBBA introduced new foreign tax allocation rules for CFCs with fiscal years that straddle the transition date.
Common foreign tax credit mistakes to avoid
Review these before filing or amending a return with FTC claims:
- Misclassified income source. Putting US-source income in the foreign-source column inflates the FTC limit and can trigger an IRS adjustment. Verify sourcing rules for each income type.
- Claiming credit for nonqualifying taxes. VAT, social security contributions, and property taxes are not creditable. Including them on Form 1116 creates an overstated credit.
- Mixing baskets on one Form 1116. Each income category requires its own form. Combining passive and general income on a single form produces the wrong limit.
- Forgetting to remove FEIE-excluded income. Income excluded under Form 2555 must be removed from the FTC calculation entirely, along with the allocable foreign taxes.
- Using the wrong exchange rate. Cash-basis filers use the rate on the date paid. Accrual-basis filers generally use the average rate for the foreign tax year. Using the wrong rate changes the dollar amount of the credit.
- Not tracking carryovers. Unused credits carry forward up to ten years by category. Losing track of Schedule B balances means leaving money on the table in future years.
- Claiming the credit on income in a tax-deferred account. Foreign taxes paid inside an IRA or other tax-deferred account do not generate a credit for the account holder.
If you need to correct an FTC-related error, filing Form 1040-X with a revised Form 1116 is the standard path – and you have up to 10 years to switch from a deduction to a credit on that amended return.

Foreign tax credit FAQ
The foreign tax credit is a nonrefundable US tax credit that reduces your federal tax bill by the amount of income tax you paid to a foreign government on income that is also taxable in the US. It prevents double taxation on foreign-source income.
There is no flat dollar cap. The foreign tax credit limit is determined by a formula: US tax before credits x foreign-source taxable income in the category / worldwide taxable income. The credit is capped at the lower of that limit or the actual foreign taxes paid.
The limit on foreign tax credit is calculated separately for each income basket – passive, general, foreign branch, and others. Excess credits generally carry back one year and forward up to ten years under IRC section 904(c). Section 951A category taxes have no carryback or carryover.
The tax must be imposed on you personally, legally owed, paid or accrued to a foreign government, and qualify as an income tax or a tax in lieu of one under IRC sections 901 and 903. VAT, property taxes, and social security contributions do not qualify.
Yes – foreign withholding on dividends or interest is creditable if the tax is compulsory and meets the income-tax or in-lieu-of-tax requirements. Treaty-rate withholding of 15% on dividends generally qualifies.
Yes – when all foreign income is passive, taxes are $300 or less for single filers, $600 or less for joint filers, all amounts appear on qualified payee statements, and all other IRS conditions are met. Estates and trusts are not eligible.
Yes, but not on the same income. Apply the FEIE to earned income and claim the FTC on other income that remains taxable in the US. A foreign tax credit example of this approach: exclude $130,000 (2025) of wages under FEIE, then credit foreign taxes paid on dividend and interest income using Form 1116.
No. Estates and trusts cannot use the de minimis election regardless of the amount of foreign taxes paid. The shortcut is available only to individual filers who meet all IRS conditions, including the passive income requirement and the qualified payee statement rule.
Claim the credit in the year the tax is paid or accrued based on your chosen method. If the foreign tax is later adjusted, amend the affected year and report the redetermination on Schedule C of Form 1116.
A treaty can re-source income into a special category that requires a separate Form 1116. When a treaty position overrides US law, disclose it on Form 8833. Treaty re-sourcing may allow US-source income to qualify for the credit.
