Form 2555 Explained: The Foreign Earned Income Exclusion Deep Dive

2026-07-09

Form 2555, Foreign Earned Income, is the gateway to excluding up to $130,000 of foreign-earned income from US tax in 2025. It's one of the most powerful forms in expat tax — and one of the most commonly botched.

How the FEIE Works

The Foreign Earned Income Exclusion lets qualifying US citizens and residents exclude foreign-earned income from their US taxable income. The maximum exclusion is $130,000 for tax year 2025 (filed in 2026), adjusted annually for inflation. Married couples filing jointly can each claim the exclusion — up to $260,000 combined, but the exclusion is per-person, not per-return. Each spouse files their own Form 2555.

Who qualifies:

A US citizen or resident alien
Whose tax home is in a foreign country
Who meets either the bona fide residence test (resident of a foreign country for an uninterrupted period covering a full tax year) or the physical presence test (physically present in a foreign country for 330 full days during any 12-month period)

What's excluded: Earned income only — wages, salary, professional fees, tips, and self-employment income from personal services. Not investment income. Not rental income (unless you materially participate and meet the real property trade or business test). Not pension distributions. Not Social Security. Not alimony. The line between earned and unearned income matters — misclassifying passive income as earned to claim the FEIE is one of the fastest ways to trigger an IRS notice.

The Physical Presence Test

You need 330 full days in a foreign country within a 12-month period. "Full day" means a 24-hour period starting at midnight. Days in transit over international waters don't count — you must be physically on foreign soil. The 12-month period doesn't have to align with the tax year. It can start on any day. Common election: start the 12-month period on your arrival date and use it as your qualifying period for this tax year.

The 330 days do not need to be consecutive. If you left the foreign country for a two-week trip to the US, that's 14 non-qualifying days. If you still hit 330 days in the 12-month period, you qualify. If you fall short by 5 days, you don't — the 330-day threshold is strict. The IRS does not grant partial exclusions for the physical presence test. It's all or nothing.

The Bona Fide Residence Test

More subjective. You must be a bona fide resident of a foreign country for an uninterrupted period that includes a full tax year. The IRS looks at:

Your intention to remain in the foreign country
The nature and length of your stay
Your living arrangements (do you have a home there, or are you in temporary housing?)
Your social, family, and economic ties to the foreign country
Whether you maintained a home in the US during the period

This test favors expats who've relocated — a lease, local bank accounts, a local doctor, kids in local school. Digital nomads who change countries every two months typically can't establish bona fide residence anywhere.

The Tax Home Requirement

Your tax home is your regular or principal place of business. If you don't have a regular place of business because of the nature of your work (remote worker, consultant), your tax home is your regular place of abode. If your abode is in the US — you maintain a US residence where you spend significant time — your tax home may still be the US. This disqualifies you from the FEIE. The tax home test is separate from the physical presence test. Meeting one doesn't guarantee the other.

Form 2555, Line by Line

Part I — General Information: Your name, SSN, occupation, employer. The date you established your foreign residence or began your physical presence qualifying period. Whether you're claiming under the bona fide residence test or the physical presence test.

Part II — Tax Home Test: Confirm your tax home was in a foreign country. If you maintained a home in the US during the period, explain the circumstances.

Part III — Physical Presence Test (if applicable): List the 12-month period you're using. The IRS wants to know the specific dates. If your qualifying period spans two tax years, you'll calculate the exclusion proportionately.

Part IV — Bona Fide Residence Test (if applicable): Statement of your foreign residence. Dates of arrival and departure. Country of residence. Type of housing.

Part V — Foreign Earned Income: Enter your foreign-earned income. If you're an employee, this is your W-2, Box 1 wages from the foreign position (plus any foreign-source wages not reported on a W-2). If you're self-employed, this is your net profit from Schedule C or the equivalent, allocated between US-source and foreign-source. Attach a statement explaining the allocation.

Part VI — Exemption Computation: This section calculates how much of the $130,000 maximum you can actually claim. If your qualifying period is shorter than the full tax year, the maximum is prorated based on the number of qualifying days divided by 365. If a calendar-year filer's qualifying period started August 1, they'd get 153 qualifying days / 365 ≈ 41.9% of the $130,000 max, or about $54,400.

Part VII — Housing Exclusion: If your housing expenses exceed a base amount, you may claim an additional housing exclusion or deduction on top of the FEIE. The housing exclusion is calculated separately and has its own limits. For 2025, the base housing amount is 16% of the FEIE maximum ($20,800), and the maximum housing exclusion is 30% of the FEIE maximum ($39,000), with higher limits in certain high-cost cities designated by the IRS.

Common FEIE Traps

Trap 1: Revoking the FEIE. Once you claim the FEIE, you can't switch to the Foreign Tax Credit for five years without IRS permission. Before claiming the FEIE, run the numbers both ways. If you're in a high-tax country whose tax rate exceeds the US rate, the FTC might be better — it generates carryover credits while the FEIE just excludes income. If your foreign country's tax rate is lower than the US rate, the FEIE is usually better because it saves you from the US tax on top of the lower foreign tax. Run the numbers before you commit.

Trap 2: Self-employment tax. The FEIE excludes income from income tax, not from self-employment tax. If you're self-employed abroad, you still pay 15.3% SE tax on your net earnings, even if the FEIE eliminates your income tax. The exception: if you're covered by a foreign social security system under a totalization agreement, you may be exempt from US SE tax. You'll need a certificate of coverage from the foreign country.

Trap 3: State residency. The FEIE is a federal exclusion. It does not affect your state tax obligations. If you maintain ties to a state with income tax, that state may still consider you a resident and tax your worldwide income. Federal FEIE and state residency are independent determinations.

Trap 4: The housing exclusion misallocation. Self-employed expats taking the housing deduction instead of the exclusion must reduce their deduction by the amount of their self-employment tax deduction. Over-claiming the housing deduction without this adjustment is a common audit trigger.

Trap 5: Mixing FEIE and FTC on the same return. You can use the FEIE for earned income and the FTC for investment income on the same return. This is common: exclude your salary with the FEIE on Form 2555, claim a credit for foreign taxes on your dividends with Form 1116. Just don't claim FEIE and FTC on the same income — no double-dipping. The IRS cross-checks Forms 2555 and 1116 for overlapping income amounts.
