Foreign Tax Credit: How Expats Can Lower Their 2026 U.S. Tax Bill

Americans abroad often pay tax where they live and still have to file with the IRS. The Foreign Tax Credit exists for that overlap.

It can reduce your U.S. tax bill when you’ve paid eligible income tax to another country, making it especially useful for expats in higher-tax countries.

But it isn’t a blanket credit for every tax paid overseas. What counts depends on the type of tax, the income it relates to, and how the credit fits with the rest of your U.S. return.

What is the Foreign Tax Credit?

The Foreign Tax Credit helps reduce your U.S. tax bill when you’ve already paid eligible income tax to another country.

It does not erase the income from your U.S. return. Instead, it gives you credit for certain foreign taxes paid or accrued, which can help reduce double taxation.

In practice, that means:

• It applies to eligible foreign income taxes: Not every overseas tax counts.
• It reduces tax directly: A credit lowers your U.S. tax liability, rather than simply reducing taxable income.
• It is usually claimed on Form 1116: Most individual taxpayers file Form 1116 with Form 1040.
• It has limits: The credit cannot always remove your full U.S. tax bill, and unused credits may need to be carried to another tax year.

The basic idea is simple: if another country has already taxed the same income, the Foreign Tax Credit may help stop the U.S. from taxing it twice.

Who can claim the Foreign Tax Credit?

U.S. citizens, green card holders, and resident aliens may be able to claim the Foreign Tax Credit if they paid or accrued eligible foreign taxes on foreign-source income.

This can include:

• Expats employed abroad
• Self-employed expats reporting income on Schedule C
• Taxpayers with foreign rental or investment income
• Taxpayers who receive qualified dividends or foreign mutual fund income
• Taxpayers in higher-tax countries
• Anyone reporting worldwide income on a U.S. tax return

The key question is not simply whether you paid tax abroad. The tax must qualify, it must relate to income reported on your U.S. return, and it must be handled correctly for U.S. tax purposes.

What foreign taxes qualify for the FTC?

The Foreign Tax Credit is not a credit for every tax you pay overseas. It is mainly for foreign income taxes, or taxes that operate like income taxes.

That distinction matters because many expats pay several types of tax abroad, from VAT to property tax to social security contributions. Some may reduce U.S. tax through the FTC. Others will not.

Tax or payment	FTC treatment
Foreign income tax	Generally creditable if it is legally owed, actually paid or accrued, and based on income.
Income tax paid to a U.S. possession	Generally creditable if it meets the same FTC rules.
Tax based on income, war profits, or excess profits	Generally creditable under IRS rules.
Tax paid in place of an income tax	Creditable only when it substitutes for an income tax, rather than being added on top of one.
VAT or sales tax	Not creditable because it is a consumption tax, not an income tax.
Property tax	Not creditable as a Foreign Tax Credit, though it may be deductible in some cases.
Penalties, interest, or fines	Not creditable because they are not income taxes.
Social security taxes	Usually not creditable, especially where a U.S. totalization agreement applies.
Taxes on income excluded under the FEIE or foreign housing exclusion	Not creditable. You cannot exclude income and also use taxes on that same income for the FTC.
Taxes paid to certain sanctioned countries	Restricted under IRS rules.

What income can the Foreign Tax Credit apply to?

The Foreign Tax Credit can apply to foreign-source taxable income when eligible foreign income tax was paid or accrued on that income.

That includes more than wages. Depending on the source rules and tax paid, the FTC can be relevant for:

• Salary and wages earned abroad
• Self-employment income
• Professional fees
• Foreign rental income
• Dividends and qualified dividends
• Interest
• Capital gains
• Foreign mutual fund income
• Other foreign-source taxable income

This is one of the main ways the FTC differs from the Foreign Earned Income Exclusion. The FEIE only applies to earned income from work performed in a foreign country. The FTC can also help with some unearned income, including foreign-taxed investment income and rental income.

The important point is not simply the type of income. The income must be reported on your U.S. return, the foreign tax must be eligible, and the same income cannot already have been excluded under the FEIE.

How does the Foreign Tax Credit reduce U.S. tax?

The Foreign Tax Credit reduces your U.S. tax bill directly. If you qualify for a $1,000 credit, that can lower your U.S. tax by $1,000.

A deduction works differently. It reduces taxable income, not the tax itself, which is why a credit is often more valuable than a deduction.

A few things affect how much FTC you can actually use:

• Your foreign taxes paid: The credit starts with eligible foreign income taxes you paid or accrued.
• Your U.S. tax liability: The FTC can reduce U.S. tax, but it generally cannot create a refund by itself.
• Your foreign-source taxable income: The credit is limited to the portion of U.S. tax connected to foreign-source income.
• Your worldwide taxable income: The IRS compares foreign-source income with your total taxable income when calculating the limit.
• Your currency conversion: If you paid tax in euros, pounds, or another foreign currency, you will usually need to convert the amounts into U.S. dollars for your return.

The result is that the FTC can be powerful, but it is not unlimited. Paying $5,000 in foreign tax does not always mean you can use the full $5,000 against your U.S. tax bill in the same year.

Can you deduct foreign taxes instead of claiming the FTC?

Yes, in some cases. The IRS lets taxpayers choose to claim qualified foreign taxes as either a credit or an itemized deduction.

The difference is simple:

• The Foreign Tax Credit reduces U.S. tax directly.
• A foreign tax deduction reduces taxable income instead.

For most expats, the credit is usually more valuable because it lowers the tax bill itself. A deduction only helps if you itemize on Schedule A, and many taxpayers take the standard deduction instead.

That said, there may be cases where deducting foreign taxes gives a better result, so it is worth comparing both options before filing.

How do you claim the Foreign Tax Credit?

To claim the Foreign Tax Credit, you report your worldwide income on Form 1040, then calculate the credit for eligible foreign taxes paid or accrued.

For most individual expats, the process looks like this:

• Report your income: Include your worldwide income on your U.S. tax return.
• Identify eligible foreign taxes: Work out which foreign income taxes qualify for the credit.
• Separate income by category: Some income categories need to be handled separately on Form 1116.
• Convert foreign currency: If you paid tax in another currency, convert the amounts into U.S. dollars.
• File Form 1116: Most individuals claim the FTC using Form 1116, filed with Form 1040.
• Keep your records: Save foreign tax returns, payment receipts, wage statements, investment records, and exchange-rate notes.

If you need to correct a prior return, you may need to file Form 1040-X. Corporations generally use Form 1118 for the Foreign Tax Credit, but individual expats usually use Form 1116.

What is the Foreign Tax Credit limitation?

The Foreign Tax Credit is not always equal to the full amount of foreign tax you paid.

The credit is limited to the part of your U.S. tax liability connected to foreign-source income. So if your foreign tax bill is higher than the credit allowed on your U.S. return, you may not be able to use the full amount right away.

A few things can affect the limit:

• Foreign-source taxable income: The FTC is tied to income from foreign sources, not your entire return.
• Worldwide taxable income: The IRS compares your foreign-source taxable income with your total taxable income.
• U.S. tax liability: The credit can reduce U.S. tax, but it is generally limited to the U.S. tax linked to foreign-source income.
• Income categories: Passive income, general income, treaty-resourced income, and other categories may need to be calculated separately.
• Investment income: Qualified dividends and capital gains can affect the calculation, so foreign investment income may need extra care.

If you cannot use the full credit this year, you may be able to carry unused Foreign Tax Credits to another tax year.

What happens to unused Foreign Tax Credits?

Sometimes, the foreign tax you pay is higher than the credit you can use on your U.S. return for that year. That does not always mean the extra credit disappears.

In many cases, unused Foreign Tax Credits can be:

• Carried back one year
• Carried forward 10 years

This is called a Foreign Tax Credit carryover, and it can be useful if your income, country of residence, foreign tax rate, or U.S. tax position changes in a future tax filing year.

A credit you cannot use this year may still reduce U.S. tax later, which is one reason the FTC can be valuable for long-term expat tax planning.

What is a foreign tax redetermination?

A foreign tax redetermination happens when the amount of foreign tax you paid or accrued changes after you file your U.S. return.

This can happen if:

• You receive a foreign tax refund
• A foreign tax authority adjusts your tax bill
• An audit changes the amount owed
• You amend a foreign tax return
• An exchange-rate issue changes the U.S. dollar amount used for the FTC

If the change affects your U.S. tax, you may need to update your Foreign Tax Credit calculation. That can mean filing Form 1040-X with a revised Form 1116 for the year affected.

In plain English: if the foreign tax number changes after filing, your U.S. return may need to change too.

How does the FTC work for business owners and foreign companies?

The Foreign Tax Credit can be more complicated when business income is involved, because the tax treatment depends on how the business is structured.

For a sole proprietor, the setup is usually more straightforward. You report the business income on Schedule C, and the FTC may apply if you paid eligible foreign income tax on that income. This does not automatically remove U.S. self-employment tax, so income tax and Social Security/Medicare tax need to be handled separately.

For a U.S. owner of a foreign company, the rules can change quickly. If the company is treated as a foreign corporation, you may need to consider:

• CFC rules: A controlled foreign corporation is a foreign corporation controlled by U.S. shareholders. These rules can require extra reporting and may bring some company income onto a U.S. shareholder’s return.
• Form 5471 reporting: U.S. persons who are officers, directors, or shareholders in certain foreign corporations may need to file Form 5471.
• GILTI or similar CFC income rules: Some U.S. shareholders may have to report certain foreign company income even if the money has not been distributed to them.
• Different FTC treatment: Foreign tax paid by a company does not always work the same way as foreign tax paid personally.

The form also depends on who is claiming the credit. Individual expats generally use Form 1116 when required. Corporations use Form 1118.

How does the Foreign Tax Credit compare with the Foreign Earned Income Exclusion?

The Foreign Earned Income Exclusion (FEIE) is the other major tax benefit many Americans abroad consider. Instead of giving you credit for tax paid to another country, the FEIE lets qualifying taxpayers exclude a set amount of foreign earned income from U.S. taxable income.

That can make the FEIE useful for expats in low-tax or no-tax countries. But it is narrower than the FTC because it only applies to earned income from work performed abroad.

	Foreign Tax Credit	Foreign Earned Income Exclusion
What it does	Reduces U.S. tax based on eligible foreign income taxes paid or accrued.	Excludes qualifying foreign earned income from U.S. taxable income.
Best suited for	Expats in higher-tax countries who have paid foreign income tax.	Expats in low-tax or no-tax countries with qualifying earned income.
Income covered	Can apply to foreign-taxed earned income and some unearned income, such as rental income, dividends, interest, or capital gains.	Applies only to earned income from work performed abroad.
Passive income	Can be useful if eligible foreign tax was paid on passive income.	Does not cover passive income.
U.S. tax credits	May preserve more access to certain U.S. credits, depending on the return.	Can affect eligibility for some credits, including the Additional Child Tax Credit.
Unused benefit	Unused credits may generally be carried back one year or forward 10 years.	Unused exclusion cannot be carried forward.
Main form	Usually Form 1116.	IRS Form 2555.
Key limitation	The credit is limited by the U.S. tax connected to foreign-source income.	The exclusion is capped annually and requires a foreign tax home plus either the Physical Presence Test or Bona Fide Residence Test.

The main rule to remember is that you cannot use both benefits on the same income. If you exclude income under the FEIE, the foreign taxes paid on that same income generally cannot be used for the Foreign Tax Credit.

What mistakes should expats avoid when claiming the Foreign Tax Credit?

The Foreign Tax Credit can be valuable, but only when the right taxes are matched to the right income. Most mistakes happen when taxpayers treat it as a blanket credit for anything paid overseas.

Watch out for these common traps:

• Assuming all foreign taxes qualify: The FTC is mainly for eligible foreign income taxes. VAT, property tax, penalties, fines, and many social security taxes usually do not count.
• Using the same income twice: If income is excluded under the FEIE or foreign housing exclusion, you generally cannot also claim the FTC for taxes paid on that same income.
• Mixing income categories: Passive income, general income, treaty-resourced income, and other categories may need to be calculated separately on Form 1116.
• Ignoring carryovers: If you cannot use the full credit this year, you may be able to carry unused Foreign Tax Credits to another tax year.
• Forgetting passive income: Foreign-taxed dividends, interest, capital gains, rental income, and mutual fund income may need separate handling.
• Mishandling investment income: Qualified dividends, capital gains, and foreign tax reported on Form 1099-DIV can affect the FTC calculation.
• Skipping currency conversion: Foreign taxes paid in another currency need to be converted into U.S. dollars for your return.
• Missing later changes: If a foreign tax refund, audit, amended return, or exchange-rate issue changes the amount of tax paid, you may need to update your FTC calculation.
• Assuming the FTC always eliminates U.S. tax: The credit is limited, so paying foreign tax does not automatically mean your U.S. tax bill disappears.
• Overlooking country restrictions: Taxes paid to certain sanctioned countries may be restricted under IRS rules.
• Choosing the credit without comparison: Some foreign taxes can be claimed as a credit or as an itemized deduction. The credit is often better, but it is still worth checking.

Keep proof of what you paid, which income it relates to, and how you converted the amounts. The FTC is much easier to defend when the paper trail is clear.

What records should expats keep for the Foreign Tax Credit?

Keep records that show what income was taxed, which country taxed it, how much tax you paid, and how you reported it on your U.S. return.

Useful records include:

• Foreign tax returns
• Wage statements or payslips
• Tax payment receipts
• Foreign rental or investment income records
• Form 1099-DIV records showing foreign tax paid through dividends or mutual funds
• Exchange rate notes for currency conversions
• Form 1116 calculations
• Foreign Tax Credit carryover records from prior years
• Amended foreign tax assessments, refunds, or audit notices
• Form 1040-X records if you amended a U.S. return

You may not need every document every year, but keeping them together makes the FTC much easier to claim, review, or correct later.
