Living abroad comes with a lot of perks — new cultures, new perspectives, and sometimes a lower cost of living. But one thing that catches many American expats off guard is that the IRS doesn’t care where you live. If you hold a U.S. passport or green card, you’re still expected to file a federal tax return every year, no matter which country you call home. That’s where the Foreign Earned Income Exclusion (FEIE) becomes one of the most valuable tools in an expat’s financial toolkit.
What Is the Foreign Earned Income Exclusion?
The FEIE is a provision in the U.S. tax code that allows qualifying Americans living and working abroad to exclude a portion of their foreign-earned income from U.S. federal income tax. For the 2024 tax year, that exclusion amount is $126,500 per person. That’s a significant chunk of income that, if you qualify, simply won’t be taxed at the federal level.
The key phrase here is “foreign earned income.” This applies to wages, salaries, and self-employment income you earn while physically working in another country. It does not cover passive income like dividends, interest, rental income, or capital gains — those are still on the table for taxation.
Who Qualifies?
There are two tests the IRS uses to determine eligibility, and you only need to pass one of them.
The Bona Fide Residence Test
This applies to U.S. citizens who have established a genuine, long-term residence in a foreign country. If you moved to Portugal on a residency visa and have been living there as a resident for a full calendar year, you’d likely qualify. The key is that your stay abroad must be indefinite or permanent in nature — not just a temporary assignment.
The Physical Presence Test
This one is more straightforward: you must be physically present in a foreign country (or countries) for at least 330 full days within any 12-month period. A common scenario is a contractor who spends most of the year working in Southeast Asia. As long as they hit that 330-day mark, they’re eligible regardless of whether they hold official residency in any country.
How to Claim the Exclusion
You claim the FEIE by filing Form 2555 along with your regular Form 1040. The form walks you through the residency or presence test, calculates your excluded amount, and factors in your housing exclusion if applicable.
Speaking of housing — there’s also a Foreign Housing Exclusion that lets qualifying expats exclude certain housing costs like rent, utilities, and insurance. This is separate from the FEIE but works alongside it, and it can provide meaningful additional relief depending on where you live.
A Few Things to Watch Out For
- Self-employment tax still applies. Even if you exclude your income under the FEIE, self-employed expats are still on the hook for Social Security and Medicare taxes.
- State taxes are a separate matter. Some U.S. states don’t recognize the FEIE and will tax your income regardless. If you still have ties to a high-tax state like California or New York, this is worth looking into carefully.
- The exclusion isn’t automatic. You have to actively elect to use it by filing Form 2555. If you’ve never filed from abroad and are catching up on back taxes, you can still claim it retroactively in most cases.
- Exceeding the limit doesn’t mean you owe on everything. If you earn more than the exclusion amount, only the excess is subject to U.S. tax — and you may be able to reduce that further using the Foreign Tax Credit for taxes paid to your host country.
Is It Always the Right Move?
Not necessarily. For expats living in high-tax countries like Germany or France, it’s sometimes more beneficial to forgo the FEIE and use the Foreign Tax Credit instead. Why? Because the credit offsets U.S. taxes dollar-for-dollar based on what you’ve already paid abroad. If you’re paying more in foreign taxes than you’d owe the IRS anyway, the credit might eliminate your U.S. tax bill entirely — without giving up your ability to contribute to an IRA or other tax-advantaged accounts (which require taxable earned income).
Tax planning for expats is genuinely nuanced, and the right strategy depends heavily on your income level, country of residence, and long-term financial goals. The FEIE is a powerful benefit, but it’s one piece of a larger puzzle. Getting the full picture — ideally with a CPA who specializes in expat taxes — can make a real difference in what you keep at the end of the year.
