The §911 Foreign Earned Income Exclusion

"Pack a suitcase, get on a plane, count to 330 days, and the first $132,900 of your salary disappears from your US tax return. Legally."

Typical Savings: $25K–$60K (per qualifying spouse) Difficulty: ★★☆☆☆ Audit Risk: Low-Medium Best For: Remote workers abroad, expat employees, digital nomads

The 60-second pitch

The United States is one of only two countries on Earth that taxes its citizens on worldwide income no matter where they live. (The other is Eritrea.) So if you're a US citizen earning $180K as a software engineer working remotely from Lisbon, the IRS still expects a check.

IRC §911 is the relief valve. If your "tax home" is in a foreign country and you pass either the Bona Fide Residence Test or the Physical Presence Test (330 full days abroad in any 365-day window), you can exclude up to $132,900 of foreign earned income in 2026. On top of that, the foreign housing exclusion wipes out rent, utilities, insurance, and parking (city-adjusted upward in expensive locations like London, Hong Kong, Geneva).

Married couples both working abroad? Each spouse gets their own $132,900 exclusion. That's over $265K of joint earned income off the top before a dollar of US federal income tax applies.

This is the cleanest, most boring, most legitimate expat strategy in the code. The IRS literally publishes the form (2555). It's not a loophole — it's the relief Congress wrote in 1962 because expats kept renouncing.

Real-world example

Diego · Senior Backend Engineer · Lisbon, Portugal

The setup. Diego, US citizen, is a senior engineer at a US fintech earning $200,000 W-2. In January 2026 his company goes fully remote and he moves to Lisbon on Portugal's digital-nomad D8 visa. His employer keeps him on US payroll. His marginal federal bracket is 32%.

The qualifying days. Diego lands in Lisbon Jan 8, 2026. He flies back to visit family for 18 days at Christmas. Total US days in 2026: 18. Total foreign days: 347. He clears 330 full days outside the US in the calendar year — passes the Physical Presence Test. Done.

The exclusion. Of his $200K salary, the first $132,900 is excluded under §911(a)(1). On Form 2555 he claims the full exclusion.

The housing exclusion. Diego pays €2,800/mo for a Lisbon apartment ($36K/yr in rent + utilities + renter's insurance). His housing-exclusion base for 2026 is roughly the amount above the §911(c) floor (~16% of $132,900). Lisbon is not on the city-adjusted list, so the standard cap applies. He excludes ~$20,000 of housing on top.

Foreign tax. Portugal NHR-2.0 regime taxes him at a flat 20% on the local-sourced portion (he restructures part of his comp to count as Portugal-source). For US purposes, after the §911 exclusion, only about $47,000 of salary remains in his US taxable income, taxed at the rate that would have applied to $200K under §911(f) "stacking" — so roughly the 24% bracket on $47K = ~$11,300 federal (before FTC for the Portuguese tax he paid on that residual).

The step-by-step checklist

Establish a foreign tax home. Your "abode" can't remain in the US. Sign a foreign lease, get a foreign address on your driver's license / mail / bank statements, register with the consulate. §911(d)(3).
Pick your test. Physical Presence Test = 330 full 24-hour days outside the US in any rolling 365-day period (easier; works your first year). Bona Fide Residence Test = you're an actual resident of a foreign country for an uninterrupted calendar year (better long-term; lets you visit the US more freely).
Count travel days correctly. A "full day" abroad is midnight-to-midnight. The day you fly out of the US counts as a US day. The day you fly back counts as a US day. Time over international waters going to a foreign country still counts as foreign once you cross 24 nautical miles.
Keep a day-log. Boarding passes, passport stamps, country entry/exit logs (Schengen Tripsit, app screenshots). Form 2555 line 14–18 asks for arrival/departure dates with each country visited.
Confirm what counts as "earned income." Salary, wages, professional fees, self-employment income for services performed abroad. Not excludable: investment income, pensions, capital gains, rental income, alimony, Social Security.
File Form 2555 with your 1040. One per qualifying spouse. Line 18 picks the test, lines 23–26 calculate the exclusion, lines 28–36 calculate the housing exclusion.
Apply the §911(f) "stacking rule" correctly. After exclusion, your remaining income is taxed at the bracket that would have applied to your full income. Most tax software handles this; verify the math on Schedule 1 + the §911 worksheet.
Layer FTC on the residual. Any income above the exclusion that's also foreign-taxed can still claim a Foreign Tax Credit on Form 1116. (See our FTC strategy page.)
Self-employed? Separate calculation. Sole proprietors can exclude the income but still owe US self-employment tax (15.3%) unless a Totalization Agreement applies. §911 does NOT exclude SE tax under §1402.
Watch the housing-exclusion cap. The IRS publishes high-cost-locality tables (Rev. Proc. 2024-26 and successors). London, Hong Kong, Singapore, Dubai, Tokyo, Geneva get higher caps; Lisbon/Mexico City/Budapest do not.
Save Form 2555 + travel docs for 6 years. The §911 exclusion is a frequent audit target for digital-nomad-style filers — the IRS wants day-count proof.
Don't accidentally lose status mid-year. A single 36-day work assignment in the US can break the Physical Presence Test. Plan US trips around the rolling 365-day window.

IRC §911(c) Foreign housing exclusion (for employees) / housing deduction (for self-employed). 2024 standard cap ≈ $37,950; 2025 indexed up. Limited by a base-housing-amount floor of 16% of the exclusion cap.
IRC §911(d)(1) Definition of "qualified individual" — must have a foreign tax home AND pass either Bona Fide Residence Test (BFR) or Physical Presence Test (PPT).
IRC §911(d)(2) Definition of "foreign earned income" — earned income from services performed in a foreign country.
IRC §911(d)(3) "Tax home" defined — the location of your principal place of business, employment, or post of duty.
IRC §911(f) The stacking rule — exclusion does not change the tax rate that applies to your remaining (non-excluded) income.
Reg §1.911-2 Detailed definitions for tax home, abode, foreign country, and the two qualifying tests.
Rev. Proc. 2024-26 (and successors) — annual high-cost-locality housing tables for §911(c).
Form 2555 / 2555-EZ (retired) The IRS form on which you elect the exclusion. Attaches to Form 1040.
IRC §1402(a) Why the FEIE does NOT exclude self-employment tax for sole proprietors — earned income for SE purposes is computed without §911.

Audit risk flags

Day-count error. The classic FEIE audit issue. A single misread boarding pass or a forgotten 5-day US business trip and you drop below 330 days, killing the entire $132,900 exclusion. Defense: Pull every passport stamp, every airline confirmation, into a spreadsheet by day. Software like Nomadtax or even a Google Sheet works.
"Abode" in the US. If your spouse and kids still live in your Texas house, your car is registered in Texas, and your mail goes to Texas, the IRS will argue your "abode" never moved — even if you personally were abroad 340 days. Defense: Move the family. Or at minimum, terminate the US lease, ship household goods, sell or rent out the US home.
Self-employment tax surprise. Sole prop or single-member LLC freelancers exclude income for income tax — and still get hit with $20K+ of SE tax. Defense: Check whether a US Totalization Agreement (currently in force with 30 countries) covers you, or restructure as a foreign corp / employee-of-foreign-payer.
State tax residency. Federal §911 says nothing about California or New York. California in particular fights the residency exit aggressively — and does not recognize the FEIE. Defense: Establish domicile in a no-income-tax state (FL, TX, NV, TN, WA, WY, SD, NH, AK) before you leave OR break CA residency cleanly with Form 540NR + closer-connection facts.
"Sailing-around-the-world" / no-foreign-country fact pattern. Digital nomads on cruise ships, in international waters, or floating between 10 countries with no >330-day base often fail the BFR and can't pinpoint a tax home. Defense: Anchor to one country with a real lease and resident permit for at least the qualifying period.
Treaty residence vs. §911. If you claim treaty residence in a foreign country for treaty benefits AND also claim FEIE, you can win — but you have to file Form 8833 disclosing the position. Defense: Coordinate the two positions on the return; never claim full nonresident treaty status (under §7701(b)(3)) and also FEIE on the same income — that's two bites at the same apple.
Housing exclusion stacked on a US employer's housing allowance. Some expats double-count: the employer's tax-free housing reimbursement AND the §911(c) exclusion. Defense: If the employer treats housing as nontaxable already, you don't get §911(c) on the same dollar. Pick one mechanism.

When NOT to do this

You earn over ~$400K abroad. The exclusion only knocks $132,900 off the top — at high incomes, FTC on the foreign tax paid usually beats FEIE because the stacking rule taxes the residual at high brackets anyway.
You live in a high-tax country (UK, Germany, France, Australia). Local tax already exceeds US tax on the same dollars. FTC > FEIE here — the foreign tax credit alone zeros out US liability with credits to spare.
You want IRA / Solo 401(k) / SEP contributions. Excluded income is NOT compensation for retirement-plan purposes. If you exclude all your earned income, you can't contribute to an IRA. Some expats deliberately under-exclude (don't elect §911 on a sliver) to preserve retirement contribution room.
You're claiming the Child Tax Credit at the refundable level. Excluded income reduces "earned income" for the refundable additional CTC. Big families may net out worse with FEIE than with FTC + child credits.
You spend > 35 days/year in the US. Even one big sales conference + a wedding + Christmas can put you over 35 days, breaking the PPT.
Your income is investment / passive / pension / rental. §911 only excludes earned income from services. None of those count.
You revoke the election. §911(e)(2) — once you revoke, you can't re-elect for 5 years without IRS consent. Don't toggle on/off year to year casually.
