Expat Tax Guide: Filing US Taxes from Abroad
Expat Tax Guide: Filing US Taxes from Abroad (FEIE, FTC, FBAR)
The United States is one of only two countries in the world (the other is Eritrea) that taxes its citizens on worldwide income regardless of where they live. If you are a US citizen or green card holder living abroad, you must file a US tax return every year — even if you owe no US tax, even if you pay taxes to your host country, and even if you have not set foot in the United States in years.
Data Notice: Expat and international tax data in “Expat Tax Guide: Filing US Taxes from Abroad” reflects 2026 projected IRS rules. Foreign income exclusions, reporting deadlines, and penalty structures change with regulatory updates. Check IRS.gov for current guidance. [expat-tax-guide]
This guide covers the Foreign Earned Income Exclusion (FEIE), Foreign Tax Credit (FTC), FBAR reporting, the key IRS forms, and the automatic filing extension for Americans abroad.
Who Must File a US Tax Return from Abroad?
| Status | Must File? |
|---|---|
| US citizen living abroad | Yes — worldwide income |
| Green card holder living abroad | Yes — worldwide income |
| US citizen who renounced citizenship | Final return required; possible exit tax |
| Nonresident alien | Only on US-source income |
The filing thresholds are the same as domestic filers. For 2026, a single filer under 65 must file if gross income exceeds ~$16,100 (the standard deduction amount). Self-employed individuals must file if net earnings exceed $400.
However, even if your income is below the filing threshold, you must file if you want to claim the FEIE or FTC. These benefits require an affirmative election on a timely filed return.
Foreign Earned Income Exclusion (FEIE)
The FEIE allows qualifying expats to exclude a significant amount of foreign earned income from US taxation.
2026 FEIE Key Numbers
| Feature | Amount |
|---|---|
| Maximum exclusion | ~$126,500 |
| Housing exclusion (base) | 16% of FEIE (~$20,240) |
| Housing exclusion (high-cost cities) | Varies — up to ~$37,950 in the highest-cost locations |
| Form | Form 2555 |
| Election | Must be made on a timely filed return (including extensions) |
Qualifying Tests
You must meet one of two tests to claim the FEIE:
Physical Presence Test:
- Present in a foreign country for at least 330 full days during any consecutive 12-month period
- The 12-month period does not need to match the calendar year
- Days spent in transit through the US count as US days (not foreign days)
- Brief trips home (holidays, emergencies) reduce your foreign day count
Bona Fide Residence Test:
- You are a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year
- The IRS evaluates your intent to live abroad, ties to the foreign country, and ties to the US
- A short trip home does not break bona fide residence, but moving back to the US does
What Counts as “Earned Income”
| Income Type | Qualifies for FEIE? |
|---|---|
| Salary and wages | Yes |
| Self-employment income | Yes |
| Bonuses and commissions | Yes |
| Investment income (dividends, interest, capital gains) | No |
| Rental income | No |
| Pension or retirement distributions | No |
| Social Security benefits | No |
The Housing Exclusion
On top of the ~$126,500 FEIE, you can exclude certain housing costs above a base amount:
| Component | Calculation |
|---|---|
| Base housing amount | 16% of FEIE (~$20,240 for 2026) |
| Housing expenses | Rent, utilities, insurance, parking (not mortgage interest or ownership costs) |
| Exclusion | Actual housing costs minus base amount, up to the cap |
High-cost cities (London, Hong Kong, Tokyo, Singapore, Zurich) have higher caps, updated annually by the IRS.
Foreign Tax Credit (FTC)
The FTC provides a dollar-for-dollar credit for income taxes paid to a foreign government, preventing double taxation.
FTC Key Rules
| Feature | Details |
|---|---|
| Form | Form 1116 (or direct claim on Form 1040 if under $300 Single / $600 MFJ) |
| Credit limit | Cannot exceed the US tax attributable to foreign-source income |
| Carryover | Unused credits carry forward 10 years, back 1 year |
| Applies to | Income taxes and equivalent taxes paid to foreign governments |
| Does not apply to | VAT, sales tax, property tax, social security taxes (unless covered by a totalization agreement) |
FEIE vs. FTC: Which Should You Use?
| Scenario | Better Choice |
|---|---|
| Living in a low-tax country (UAE, Singapore, Hong Kong) | FEIE — exclude income that would otherwise be taxed by the US, and no foreign credits available anyway |
| Living in a high-tax country (UK, France, Germany, Japan) | FTC — your foreign tax likely exceeds US tax, generating credits that carry forward |
| Self-employed in a moderate-tax country | Often a combination — FEIE for earned income, FTC for any remainder |
| High investment income | FTC — FEIE does not cover investment income |
| Income above ~$126,500 | FTC for the portion above the FEIE limit |
Combining FEIE and FTC
You can use both, but you cannot claim the FTC on income already excluded under the FEIE. The FTC applies only to the income that remains taxable after the FEIE exclusion.
Example: You earn $200,000 abroad and pay $40,000 in foreign income tax. You exclude ~$126,500 under the FEIE, leaving $73,500 taxable. The FTC can offset the US tax on that $73,500, but only the portion of your foreign tax attributable to that income (roughly $73,500 / $200,000 x $40,000 = ~$14,700).
See the tax brackets guide to calculate your US tax liability on the non-excluded portion.
FBAR: Report of Foreign Bank Accounts
The FBAR (FinCEN Form 114) is a reporting requirement separate from your tax return. It is filed with the Financial Crimes Enforcement Network (FinCEN), not the IRS.
Who Must File
You must file an FBAR if you have a financial interest in or signature authority over foreign financial accounts with an aggregate value exceeding $10,000 at any time during the calendar year.
What Counts as a Foreign Financial Account
| Account Type | Reportable? |
|---|---|
| Foreign bank accounts (checking, savings) | Yes |
| Foreign brokerage accounts | Yes |
| Foreign mutual funds | Yes |
| Foreign retirement accounts (some) | Yes |
| Foreign life insurance with cash value | Yes |
| Cryptocurrency on a foreign exchange | Under current guidance — consult a professional |
| US accounts at US banks | No (even if you access them from abroad) |
FBAR Key Details
| Feature | Details |
|---|---|
| Threshold | $10,000 aggregate across all foreign accounts at any point in the year |
| Filing deadline | April 15 (automatic extension to October 15) |
| Filed with | FinCEN (electronically at BSA E-Filing) |
| Penalty for non-filing | Up to $10,000 per violation (non-willful); up to $100,000 or 50% of account balance per violation (willful) |
| Criminal penalties | Possible for willful failure |
The $10,000 threshold is aggregate, not per-account. If you have three foreign accounts with $4,000, $3,500, and $3,000 at any point during the year, you must file an FBAR.
FATCA: Form 8938
In addition to the FBAR, the Foreign Account Tax Compliance Act (FATCA) requires reporting foreign financial assets on Form 8938 (filed with your tax return).
FATCA Thresholds for Expats
| Filing Status | Year-End Value | Anytime During Year |
|---|---|---|
| Single (abroad) | $200,000 | $300,000 |
| MFJ (abroad) | $400,000 | $600,000 |
| Single (US resident) | $50,000 | $75,000 |
| MFJ (US resident) | $100,000 | $150,000 |
FATCA and FBAR overlap but are separate requirements. You may need to file both for the same accounts.
Automatic Filing Extension for Expats
US citizens and resident aliens living abroad receive an automatic 2-month extension to file (to June 15), with no need to file Form 4868. However, interest on any unpaid tax accrues from the original April 15 deadline, not June 15.
| Extension | Deadline | Interest Accrues From |
|---|---|---|
| Automatic 2-month (abroad) | June 15 | April 15 |
| Additional extension (Form 4868) | October 15 | April 15 |
| Combat zone extension | 180 days after leaving zone | After extension period |
If you owe tax, pay as much as possible by April 15 to minimize interest. See our tax filing deadlines guide for the complete 2026 calendar.
Self-Employment Tax for Expats
The FEIE does not exclude self-employment income from self-employment tax (Social Security and Medicare). Even if you exclude $126,500 under the FEIE, you still owe approximately 15.3% SE tax on net self-employment earnings.
Totalization Agreements
The US has totalization agreements with approximately 30 countries. If you are covered under a foreign country’s social security system and that country has a totalization agreement with the US, you may be exempt from US self-employment tax (and vice versa). You must obtain a Certificate of Coverage from the foreign country’s social security agency.
Countries with totalization agreements include: Australia, Canada, France, Germany, Ireland, Italy, Japan, South Korea, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom (among others).
See our self-employment tax guide for the full SE tax calculation.
Common Expat Tax Mistakes
| Mistake | Consequence |
|---|---|
| Not filing at all (“I don’t owe tax”) | Penalties, inability to claim FEIE/FTC, potential passport revocation for seriously delinquent tax debt |
| Missing FBAR filing | Up to $10,000 per violation (non-willful); criminal penalties possible |
| Claiming FEIE without Form 2555 | Exclusion not valid without the form |
| Failing to report foreign pension income | IRS treats unreported income as tax evasion |
| Using FEIE when FTC would save more | Leaves money on the table in high-tax countries |
| Not paying estimated taxes | Underpayment penalties from April 15 |
Renouncing Citizenship: The Exit Tax
US citizens who renounce citizenship and “covered expatriates” (those with net worth over $2 million, or average annual net income tax over ~$201,000 for the 5 years before expatriation) face a mark-to-market exit tax. All worldwide assets are treated as sold at fair market value the day before expatriation, with gains above ~$866,000 (2026 projected) subject to capital gains tax.
Frequently Asked Questions
Do I still need to file if I owe no US tax? Yes. Filing is required to claim the FEIE or FTC. Failing to file can result in penalties and loss of these benefits.
Can I contribute to a Roth IRA while living abroad? Only if you have US-source earned income or foreign earned income that you do not exclude under the FEIE. If you exclude all your earned income, you have no qualifying income for IRA contributions.
What about state taxes? Some states (California, New Mexico, South Carolina, Virginia) continue to tax former residents who move abroad. Others (Texas, Florida, Nevada) have no income tax. Establishing domicile in a no-income-tax state before moving abroad can eliminate state tax obligations.
Is foreign rental income taxable? Yes. Rental income is not eligible for the FEIE but may qualify for the FTC if your host country taxes it. Report on Schedule E.
What if I have not filed for several years? The IRS Streamlined Filing Compliance Procedures allow qualifying expats to catch up by filing 3 years of returns and 6 years of FBARs with reduced penalties (zero penalties if you qualify as non-willful). See the IRS payment plans guide for additional options.
