Foreign Tax Credit vs Deduction: Which Is Better?
US Expat Tax
The credit wins in nearly every case. The deduction is a fallback for the foreign taxes the credit refuses or strands.
Expats who paid foreign income tax can claim it against their US tax as a credit or write it off as an itemized deduction. The IRS says in Publication 514 that the credit is better in most cases. The deduction survives for a narrow set of returns where the credit is refused or stranded by its own limit.
The gap between the two is large. The credit removes foreign tax from the US tax you owe, dollar for dollar. The deduction trims taxable income, so the saving is a fraction of the tax you paid, and it reaches only the minority of expats who itemize. Here is how to tell which one belongs on your return.
Foreign tax credit (Form 1116): cuts US tax owed dollar for dollar. No itemizing. Limited each year to the US tax on your foreign-source income; unused credit carries back 1 year and forward 10 years. Form 1116 can be skipped when foreign tax is $300 or less ($600 joint) and all of it is passive.
Foreign tax deduction (Schedule A): lowers taxable income only. Requires itemizing, so total itemized deductions must beat the 2026 standard deduction of $16,100 single or $32,200 joint. Unused amounts are lost.
Both: the choice is all or nothing for the year. The one exception is a tax the credit refuses, such as tax paid to a sanctioned country, which you can deduct in the same year you credit the rest.
The foreign tax credit: dollar for dollar
The credit is claimed on Form 1116 and subtracts foreign income tax from the US tax you owe, dollar for dollar. It has nothing to do with itemizing. You keep the full standard deduction and take the credit on top of it. The choice is made each year and covers all of your qualified foreign taxes for that year, as the IRS sets out on its credit or deduction page.
The credit has a ceiling. Each year it is limited to the US tax on your foreign-source income. Foreign tax above that line is stranded for the year. Unused credit carries back 1 year and forward 10 years, and the Form 1116 instructions cover the carryover.
Small amounts get a shortcut. If your foreign tax for the year is $300 or less ($600 joint) and all of it is on passive income, you can claim the credit without filing Form 1116 at all, per IRS Topic 856. Two categories get no credit: taxes paid to a sanctioned country, and taxes on income you excluded under the foreign earned income exclusion.
The foreign tax deduction: Schedule A only
The deduction goes on Schedule A of Form 1040 with your other itemized deductions. It lowers taxable income. The saving is the deduction multiplied by your bracket, a fraction of the foreign tax you paid.
It only works if you itemize. Total itemized deductions have to beat the standard deduction, which for 2026 is $16,100 for single filers and $32,200 for joint filers under Rev. Proc. 2025-32. Most expats do not itemize, so the deduction often saves nothing. Whether you clear that bar depends on your other deductions, and the SALT deduction cap page covers the state and local piece.
The deduction has no annual limit and no carryover. Whatever you cannot use in the year is gone. It does accept one thing the credit refuses: tax paid to a sanctioned country is deductible on Schedule A, even in a year you credit everything else.

- Effect on US tax: cuts tax owed dollar for dollar
- Where claimed: Form 1116, or no form if $300 or less ($600 joint) and all passive
- Itemizing required: no
- Annual limit: US tax on foreign-source income
- Unused amount: carry back 1 year, forward 10 years
- Sanctioned-country taxes: not allowed
- Typical winner: nearly every expat who paid foreign income tax
Foreign tax deduction (Schedule A)
- Effect on US tax: lowers taxable income only
- Where claimed: Schedule A, Form 1040
- Itemizing required: yes
- Annual limit: none, though itemizing must beat the standard deduction
- Unused amount: lost, no carryover
- Sanctioned-country taxes: allowed, even in a credit year
- Typical winner: itemizers whose credit is mostly stranded
Where people get it wrong
The most common mistake is treating the two as interchangeable. A $5,000 foreign tax taken as a credit removes $5,000 of US tax. The same $5,000 taken as a deduction saves about $1,200 for a filer in the 24 percent bracket, and only if total itemized deductions exceed the 2026 standard deduction of $16,100 single or $32,200 joint. Most expats do not itemize, so the deduction often saves nothing.
The second mistake is mixing methods. The choice is all or nothing for the year: credit every qualified foreign tax or deduct every one. You can switch the next year. Only taxes the credit refuses, such as sanctioned-country taxes, can be deducted alongside a credit in the same year.
A third mistake is claiming either method on excluded income. Taxes on income excluded under the foreign earned income exclusion get neither the credit nor the deduction. Our foreign tax credit guide covers the Form 1116 limit math.
The choice is made year by year, so a stranded credit in one year does not commit you to the deduction the next. Expats who claim the foreign earned income exclusion should first work out which foreign taxes are left to credit at all, since tax on excluded income qualifies for neither method. The US expat tax guide covers the exclusion.
The verdict
Foreign tax credit when you paid foreign income tax and the Form 1116 limit lets you use most of it now or within the 10-year carryforward.
Foreign tax deduction when you itemize anyway, the limit strands most of the tax, and the carryover has no realistic use.
Both when the credit is refused for a specific tax, such as one paid to a sanctioned country, which you can deduct in the same year you credit the rest.

Get the credit right
Nearly every expat who paid foreign income tax belongs on Form 1116, and the deduction is worth a look only when the limit strands most of the credit. If you are not sure how much of your foreign tax the limit lets through, or you have been deducting when you should have been crediting, the answer comes out of the Form 1116 limit math.
