Foreign Tax Credit vs Foreign Earned Income Exclusion: Which Should US Expats Use?

Every US citizen and green card holder must file a US tax return on worldwide income, no matter where they live. To stop the same income being taxed twice — once abroad and once by the IRS — expats use one of two mechanisms: the Foreign Earned Income Exclusion (FEIE) on Form 2555, or the Foreign Tax Credit (FTC) on Form 1116. Choosing the wrong one can cost thousands of dollars a year and quietly disqualify you from other benefits. This guide explains how each works, when each wins, and how to combine them.

How the Foreign Earned Income Exclusion works

The FEIE lets you exclude foreign earned income from your US taxable income entirely. For tax year 2026 the maximum exclusion is $132,900 per qualifying person (up from $130,000 in 2025). If both spouses work abroad and each qualifies, a couple can exclude up to $265,800 combined.

To claim it, you must have a tax home abroad and pass one of two tests:

• Physical Presence Test — you are physically present in a foreign country for at least 330 full days during any 12-month period.
• Bona Fide Residence Test — you are a bona fide resident of a foreign country for an uninterrupted period that includes a full tax year (generally only available to citizens, or residents of treaty countries).

The FEIE only covers earned income — wages, salary, and self-employment profits. It does not cover dividends, interest, capital gains, rental income, or pension and Social Security distributions. There is also a related Foreign Housing Exclusion that can shelter part of your foreign housing costs above a base amount.

How the Foreign Tax Credit works

The FTC gives you a dollar-for-dollar credit against your US tax bill for income taxes you actually paid to a foreign government. Pay €20,000 of French or German income tax and you get (broadly) a $20,000-equivalent credit against the US tax on that same income. Unlike the FEIE, the FTC works on nearly all categories of income — earned income, dividends, interest, capital gains, and rental income — as long as foreign tax was paid on it.

The credit is limited to the US tax attributable to your foreign income (you cannot use foreign taxes to offset US tax on US-source income). When the foreign tax you paid exceeds that limit — which is common in high-tax countries — the excess becomes a carryover: back 1 year and forward up to 10 years. Those banked credits are valuable: they can wipe out US tax in a later year when your foreign rate dips below the US rate.

The decision: which one wins?

The single biggest factor is how your foreign income-tax rate compares to your US rate.

High-tax country → Foreign Tax Credit

In France, Germany, the UK, Spain, the Netherlands, Italy and most of Western Europe, combined income-tax rates routinely exceed US rates. The FTC typically eliminates your US income tax on that income and generates excess credits you carry forward. The FTC also keeps your income "on the books" for the IRS, which preserves access to the refundable Additional Child Tax Credit and lets you contribute to a US IRA (see below). For most European expats, the FTC is the default choice — which is why our country guides for France, Germany, and the UK all recommend it.

Low- or no-tax country → Foreign Earned Income Exclusion

If you live somewhere with little or no income tax — the UAE, Qatar, the Cayman Islands, or certain income under territorial systems like Singapore — there are few or no foreign taxes to credit, so the FTC gives you nothing. Here the FEIE shines: it removes up to $132,900 of earned income from US tax with no foreign tax needed at all.

The in-between case

In moderate-tax countries, or when your income sits near the exclusion amount, the answer depends on your exact numbers, family situation, and retirement-saving plans. This is where a cross-border tax professional earns their fee — the difference between the two methods can be several thousand dollars.

The hidden costs of the FEIE

The exclusion looks simple and "free," but it has consequences expats often miss:

• It can disqualify the refundable Child Tax Credit. Excluded income is not "earned income" for the Additional Child Tax Credit. Families with children frequently get a larger refund using the FTC instead of the FEIE.
• It can block IRA contributions. You need taxable compensation to contribute to an IRA or Roth IRA. If the FEIE excludes all your earned income, you may have no eligible compensation left to contribute.
• The stacking rule. Income above the exclusion is taxed starting at the bracket it would have fallen in without the exclusion — the FEIE does not push your remaining income into the lowest brackets.
• The 5-year revocation lock. If you switch off the FEIE, you generally cannot use it again for five years without IRS permission.

Can you use both? Yes — carefully

You can use the FEIE and FTC together, just not on the same income. A common combination:

• Exclude your salary up to $132,900 with the FEIE.
• Claim the FTC on foreign taxes paid on income above the exclusion, and on investment income (dividends, interest, capital gains) the FEIE can never cover.

There is a catch: foreign tax paid on the excluded portion of income is not creditable (you cannot exclude income and also credit the tax on it). The math must be done carefully, and in high-tax countries it usually turns out that going FTC-only is both simpler and produces a better result. For investment-heavy expats, the FTC is also what handles foreign tax withheld on dividends — see how this interacts with foreign funds in our PFIC and Form 8621 guide.

Switching between methods

You elect the FEIE by filing Form 2555. You can switch from the FEIE to the FTC freely in any year, but doing so revokes the exclusion — and the five-year lock then applies before you can elect it again. Switching from FTC to FEIE is unrestricted. Because of the lock, treat a move off the FEIE as a long-term decision, not a single-year experiment. This frequently comes up for expats catching up on past returns through the Streamlined Filing Procedures, where choosing the right method across three back-years matters.

How treaties fit in

Tax treaties decide which country has the primary right to tax each type of income; the FEIE and FTC are the US-side tools that then eliminate the double tax. Treaties also add special rules — for example, resourcing US-source income as foreign so the FTC can offset it. For the bigger picture, read our double taxation treaties guide.

Bottom line

If you live in a high-tax country — which covers most of Europe — start with the assumption that the Foreign Tax Credit is your tool: it eliminates US tax, builds carryforwards, and preserves the Child Tax Credit and IRA contributions. Reach for the FEIE when you live somewhere with little or no income tax. And whatever you choose, track the foreign taxes you pay and your foreign account balances carefully — both feed directly into Form 1116 and your FBAR/FATCA filings.
