Form 2555 and the Foreign Earned Income Exclusion: Who Qualifies and How It Works

The Foreign Earned Income Exclusion is the best-known tax benefit for Americans abroad, and Form 2555 is how you claim it. For 2025 it excludes up to $130,000 of foreign wages or self-employment income from U.S. income tax, which for many expats reduces the U.S. bill to zero. But the exclusion has edges that surprise people: it covers earned income only, it does nothing for self-employment tax, and for expats in high-tax countries it is often the wrong choice entirely.

Who Can Claim It

Three requirements, all mandatory:

1. Your tax home is in a foreign country. Your main place of work is abroad, not temporarily, and you do not maintain your abode in the U.S.
2. You have foreign earned income. Pay for personal services you performed in a foreign country.
3. You pass one of two tests: physical presence or bona fide residence.

The tests are where qualification is won or lost, so they deserve their own sections.

The Physical Presence Test: 330 Days

You qualify if you are physically present in one or more foreign countries for at least 330 full days during any 12-month period. The mechanics matter more than the summary:

• Full days only. A day counts only if you spend all 24 hours, midnight to midnight, in foreign countries. The day you fly out of the U.S. and the day you land back generally do not count.
• Any 12-month window. The period does not have to match the calendar year. Someone who moved abroad in June can qualify using a June-to-June window, with the exclusion prorated for the portion of the tax year inside it.
• The 35 days are the budget. 330 foreign days leaves at most 35 days for U.S. visits, and travel days at each end of every trip eat into it. Two or three U.S. trips a year can consume the margin faster than expected. Time in international waters or airspace beyond 24 hours does not count as foreign either, a detail that catches cruise passengers and some flight itineraries.

The count is mechanical, which makes it both objective and unforgiving; a two-day miscount can eliminate the entire exclusion. Our guide to the physical presence test covers day counting, window selection, and the travel-day traps in detail.

The Bona Fide Residence Test

The alternative test is qualitative: you are a bona fide resident of a foreign country for an uninterrupted period that includes a full calendar year (January 1 through December 31). It is available to U.S. citizens, and to green card holders who are residents of a country with a U.S. tax treaty.

Bona fide residence is about the character of your presence, not a day count. The IRS looks at where your home and family are, your visa and immigration status, whether you pay taxes as a resident of that country, and whether your move has the shape of a life relocated rather than an extended assignment. Crucially, it is not the same as domicile: you can remain domiciled in Florida in the legal sense, intending to return someday, and still be a bona fide resident of Mexico or Portugal for this test. Occasional U.S. visits do not break bona fide residence the way they break a 330-day count, which is the test’s main practical advantage.

How to choose: most expats use physical presence for the first partial year abroad, when no full calendar year of residence exists yet, and switch to bona fide residence once a full calendar year has been established. Settled expats generally prefer bona fide residence because it frees them from counting travel days. Digital nomads who never establish residency anywhere are usually stuck with physical presence permanently, and need to track days accordingly.

What Income Qualifies: Earned Income Only

The exclusion applies to foreign earned income: compensation for personal services performed in a foreign country. Wages, salary, bonuses, commissions, and net self-employment earnings all qualify, and “foreign” is determined by where you did the work, not where the employer sits or which bank the pay lands in. A remote employee in Buenos Aires paid by a U.S. company into a U.S. account has foreign earned income.

What does not qualify:

• Passive income: dividends, interest, capital gains, rental income, royalties from investments
• Pension and retirement distributions, including Social Security
• Pay from the U.S. government to its employees
• Income earned in the U.S.: days worked physically in the U.S., even during a qualifying year, produce U.S.-source earned income outside the exclusion

A portfolio abroad, a rental property, or an IRA distribution is untouched by Form 2555. For expats whose income is mostly passive, the FEIE solves little, and the Foreign Tax Credit and treaty analysis carry the load instead.

The Foreign Housing Exclusion

Qualifying for the FEIE also opens the foreign housing exclusion, claimed on the same Form 2555. It shelters reasonable foreign housing costs (rent, utilities other than phone and TV, insurance, parking) to the extent they exceed a base amount of $20,800 for 2025, up to a general cap of $39,000 that the IRS raises substantially for high-cost cities on its annual list. An expat paying $36,000 rent in a listed city excludes roughly $15,200 beyond the earned income exclusion. Employees use the housing exclusion; the self-employed take the equivalent as a housing deduction. In expensive markets (London, Singapore, Hong Kong, Dubai), the housing piece is often worth five figures and routinely gets missed.

FEIE and the Foreign Tax Credit: One Set of Dollars, One Benefit

You cannot claim the Foreign Tax Credit (Form 1116) for foreign taxes paid on income you excluded; that would be a double benefit on the same dollars. The two can be combined across different income: exclude wages up to $130,000, then credit foreign taxes attributable to income above the cap or to passive income. Two mechanical points shape the outcome:

• The stacking rule. Excluded income still sets your bracket. Income above the exclusion is taxed at the rates that would apply had nothing been excluded, so the exclusion does not push your remaining income into low brackets.
• The five-year lockout. The FEIE is elected on Form 2555 and stays in effect until revoked. Revoke it (by switching to the FTC on foreign earned income) and you generally cannot re-elect it for five years without IRS consent. The choice is sticky, which is why it should be made deliberately the first year abroad.

Self-Employment Tax: The Exclusion Does Not Help

The FEIE reduces income tax only. A self-employed expat who excludes every dollar of profit still owes 15.3% self-employment tax on net earnings, a bill that surprises freelancers abroad every filing season. The exception runs through totalization agreements: treaties that assign social security coverage to one country. An American freelancer covered by the social security system of an agreement country (the list includes Canada, most of Europe, and in Latin America: Mexico’s agreement remains unratified, but Brazil, Chile, and Uruguay are in force) can be exempt from U.S. SE tax with a certificate of coverage. No agreement, as with Argentina or Colombia, means SE tax is owed regardless of the FEIE, and structuring questions (including an S-corp or foreign employer arrangement) become worth asking.

When the Foreign Tax Credit Beats the FEIE

The comparison that actually matters is not “can I claim the FEIE” but “should I”:

• High-tax country (UK, Germany, Spain, Canada, Australia, Japan): the FTC usually wins. Foreign taxes exceed the U.S. liability, excess credits carry forward ten years, income above $130,000 is fully covered, and unlike the FEIE, credited income still counts as earned income for IRA contributions and the additional child tax credit, which the FEIE can forfeit.
• Low-tax or no-tax country (UAE, Singapore at expat rates, much of the Gulf): the FEIE usually wins, because there is little or no foreign tax to credit.
• Income above the exclusion: blended. FEIE on the first $130,000 plus housing, FTC on the rest, run both ways to compare.

The full decision framework, including the IRA and child tax credit angles, is in our FEIE vs. FTC comparison .

When to Seek Help

A salaried expat, settled in one country, comfortably past 330 days: Form 2555 is routine. The judgment calls arrive with a first partial year abroad (window selection and proration), self-employment income (SE tax and totalization), a high-tax country where electing the FEIE at all may be the wrong move, or a return to the U.S. on the horizon, where this year’s election shapes the next five. The FEIE is the most valuable line on an expat return and also the easiest to claim reflexively when the credit was the better answer. It is the starting point of our international tax practice for Americans abroad, and the election deserves a real comparison before the first Form 2555 is filed.
