Yes. U.S. citizens do pay taxes on foreign income. If you hold a U.S. passport, the federal government taxes your worldwide income no matter where you live or where the money was earned, so wages from a job in Berlin, rent from a flat in London, and dividends from an account in Singapore all belong on your U.S. return. Two big provisions soften the bill for most people abroad: the foreign earned income exclusion, which for 2026 shields up to $132,900 of earned income, and the foreign tax credit, which offsets what you already paid to another country.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill
Why Citizenship Alone Triggers the Tax
The rule comes straight from the tax code. Section 61 defines gross income as “all income from whatever source derived,” and Section 1 imposes the tax on every individual’s income.2Office of the Law Revision Counsel. 26 USC 61 Gross Income Defined3Office of the Law Revision Counsel. 26 USC 1 Tax Imposed Neither section carves out foreign earnings, so wages, interest, rents, business profits, capital gains, pensions, and royalties all count regardless of the country that produced them.
The obligation follows your citizenship, not your street address. A U.S. citizen files a U.S. return whether they live in Dallas or Dubai. Lawful permanent residents are in the same position: green card holders are U.S. tax residents from the moment residency starts until it is formally terminated through immigration channels, even during years spent entirely outside the country.4Internal Revenue Service. U.S. Tax Residency – Green Card Test5Internal Revenue Service. Tax Information and Responsibilities for New Immigrants to the United States
One point worth flagging up front: a U.S. tax treaty with your host country almost never changes any of this. Nearly every U.S. treaty contains a saving clause that preserves the right to tax U.S. citizens as if the treaty didn’t exist.6Internal Revenue Service. Tax Treaties Can Affect Your Income Tax Treaties mainly help prevent double taxation; they do not exempt citizens from filing.
The Foreign Earned Income Exclusion
The single largest tax break for Americans abroad is the foreign earned income exclusion under Section 911. For 2026, qualifying taxpayers can exclude up to $132,900 of foreign earned income from U.S. taxable income.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill The exclusion covers earned income only: wages, salary, and self-employment income. Investment income, pensions, and Social Security benefits don’t qualify.
To claim it, you need a tax home in a foreign country (your regular place of business is abroad and you don’t maintain a primary residence in the U.S.), and you have to pass one of two tests.7Internal Revenue Service. Foreign Earned Income Exclusion
Physical Presence Test
This one is arithmetic. You must be physically present in a foreign country for at least 330 full days during any 12 consecutive months.8Internal Revenue Service. Foreign Earned Income Exclusion – Physical Presence Test The days don’t have to be consecutive, and the 12-month window doesn’t have to line up with the calendar year. Time in transit over international waters or airspace doesn’t count for either side. Any moment on U.S. soil during a day, even a layover, breaks that day.
Personal reasons like family emergencies or delayed flights don’t earn an exception. The IRS does grant a waiver when war or civil unrest forces you to leave a foreign country, and it publishes a list of qualifying countries and effective dates each year.9Internal Revenue Service. Exceptions to the Bona Fide Residence and the Physical Presence Tests
Bona Fide Residence Test
This test is more flexible but harder to prove. You qualify if you are a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year (January 1 through December 31 for calendar-year filers).10Internal Revenue Service. Foreign Earned Income Exclusion – Bona Fide Residence Test Short trips home don’t automatically disqualify you, but the IRS weighs the full picture: your lease, whether family moved with you, local ties, and how long you intend to stay.
Timing matters. Arrive in November 2025 on an indefinite assignment and the earliest you complete a full-tax-year residency is December 31, 2026. Someone who transfers back before that year closes won’t pass this test, though the physical presence test may still work.
The Housing Add-On
On top of the income exclusion, you can claim a foreign housing exclusion (or deduction, if self-employed) for qualifying housing costs above a base amount. For 2026 the base is roughly $21,264 (16% of the $132,900 cap) and qualifying expenses are generally capped at $39,870 (30% of the cap), with the IRS adjusting the cap upward for high-cost cities.11Internal Revenue Service. Figuring the Foreign Earned Income Exclusion Qualifying costs include rent, utilities other than phone and TV, insurance, and parking. Both the income exclusion and the housing piece are claimed on Form 2555.
The Foreign Tax Credit
When you pay income tax to a foreign government on the same income, Section 901 lets you claim a dollar-for-dollar credit against your U.S. tax on Form 1116.12Office of the Law Revision Counsel. 26 USC 901 Taxes of Foreign Countries and of Possessions of United States You categorize your foreign income by type (passive income like dividends in one column, general income like wages in another) and calculate the credit for each category separately.
The credit is capped at the U.S. tax that would apply to the same foreign income. Earn $100,000 abroad at a 40% foreign rate while your U.S. effective rate on that income is 24%, and the credit is limited to the U.S. rate. Excess amounts generally carry back one year or forward ten.
You cannot double up. Once income is excluded under the FEIE, any foreign tax you paid on that excluded income is off-limits for the credit.13Internal Revenue Service. Choosing the Foreign Earned Income Exclusion If your foreign tax rate is high, the credit alone often wipes out your U.S. liability and the exclusion adds nothing. If your foreign tax rate is low, the exclusion typically saves more. Run the numbers both ways before you file.
Self-Employment Tax Is Not Excluded
Here’s the expensive surprise. The foreign earned income exclusion does not reduce self-employment tax. If you freelance, consult, or run a business abroad with net earnings of $400 or more, you owe the 15.3% combined Social Security and Medicare tax on your full net self-employment income, even if every dollar is excluded from income tax by the FEIE.14Internal Revenue Service. Self-Employment Tax for Businesses Abroad
The one way out is a totalization agreement. The U.S. has these with about 30 countries, including Canada, the United Kingdom, Germany, Japan, Australia, and France, and they prevent double taxation of Social Security contributions.15Social Security Administration. U.S. International Social Security Agreements If you work in a country covered by one, you generally pay into only one system, and a Certificate of Coverage from the Social Security Administration documents which. Work in a country without an agreement and you can end up paying into both.
Reporting Your Foreign Accounts
Paying the right tax is only half the job. Holding foreign financial accounts triggers separate reporting rules with penalties that dwarf the tax itself.
FBAR (FinCEN Form 114)
If the combined value of your foreign bank and financial accounts exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts.16eCFR. 31 CFR 1010.350 – Reports of Foreign Financial Accounts The FBAR is filed separately from your tax return through the BSA E-Filing System operated by the Financial Crimes Enforcement Network.17Financial Crimes Enforcement Network. BSA E-Filing System – File FBAR You’ll need each account’s maximum balance during the year, the account number, and the name and address of the financial institution.
The FBAR is due April 15 with an automatic extension to October 15 that requires no separate request.18Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) Non-willful penalties can reach $10,000 per account per year (adjusted for inflation). Willful violations carry the greater of $100,000 (also inflation-adjusted) or 50% of the account balance.19Taxpayer Advocate Service. Modify the Definition of Willful for Purposes of Finding FBAR Violations and Reduce the Maximum Penalty Amounts
FATCA (Form 8938)
The Foreign Account Tax Compliance Act adds a second layer for specified foreign financial assets: not just bank accounts but also foreign stocks, securities, financial instruments, and interests in foreign entities. Form 8938 attaches to your tax return.20Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers Thresholds depend on where you live and how you file:
- Living in the U.S., unmarried: total value over $50,000 on the last day of the year, or $75,000 at any point during the year.
- Living abroad, unmarried: over $200,000 on the last day, or $300,000 at any point.
- Married filing jointly, living in the U.S.: $100,000 and $150,000, respectively.
- Married filing jointly, living abroad: $400,000 and $600,000, respectively.
Failing to file Form 8938 triggers a $10,000 penalty, with up to $50,000 in additional penalties for continued noncompliance after IRS notice.21eCFR. 26 CFR 1.6038D-8 Penalties for Failure To Disclose The FBAR and Form 8938 overlap in what they cover, but filing one does not excuse the other.
A Few Other Reporting Traps
Receiving more than $100,000 during the year in gifts or inheritances from a nonresident alien or foreign estate isn’t itself taxable, but it must be reported on Part IV of Form 3520. Gifts from foreign corporations or partnerships have a much lower threshold (around $19,570 in recent years, adjusted for inflation). Missing this form can cost 25% of the unreported amount.22Internal Revenue Service. Gifts From Foreign Person
Distributions from a foreign pension or annuity are generally taxable in the U.S. the same way a domestic pension is, and the absence of a Form 1099 doesn’t change that.23Internal Revenue Service. The Taxation of Foreign Pension and Annuity Distributions Foreign social security benefits work similarly unless a specific treaty provision says otherwise.
Buying a mutual fund, ETF, or similar pooled investment domiciled outside the U.S. can trigger the Passive Foreign Investment Company (PFIC) rules, which are among the harshest in the tax code. Gains and “excess distributions” get spread across your entire holding period and taxed at the highest marginal rate for each year, plus an interest charge, on a separate Form 8621 for each holding.24Internal Revenue Service. Instructions for Form 8621 Investing through U.S.-domiciled funds while living abroad avoids the problem.
Deadlines If You Live Abroad
Americans living and working abroad on April 15 get an automatic two-month extension to file, pushing the deadline to June 15. No form is required; you attach a statement to the return explaining which condition you met.25Internal Revenue Service. U.S. Citizens and Resident Aliens Abroad – Automatic 2-Month Extension of Time To File
The catch: it’s a filing extension, not a payment extension. Interest on unpaid tax runs from April 15 regardless.26Internal Revenue Service.

All amounts on the return must be in U.S. dollars. The IRS accepts any consistently used posted rate from a bank, the Federal Reserve, or Treasury, and also publishes yearly average exchange rates for taxpayers whose income arrives evenly through the year.29Internal Revenue Service. Foreign Currency and Currency Exchange Rates30Internal Revenue Service. Yearly Average Currency Exchange Rates Whichever method you pick, use it consistently.
Catching Up If You Didn’t Know
If you’ve been living abroad and didn’t realize you needed to file U.S. returns or FBARs, the streamlined filing compliance procedures are built for taxpayers whose failure was non-willful (negligence, inadvertence, mistake, or a good-faith misunderstanding). You file three years of delinquent returns and six years of FBARs.31Internal Revenue Service. Streamlined Filing Compliance Procedures
Taxpayers who live outside the U.S. use the streamlined foreign offshore procedures, which impose no penalties on the delinquent filings. Taxpayers living in the U.S. use the domestic version and pay a 5% miscellaneous offshore penalty on the highest aggregate balance of the unreported accounts. Neither option is available once the IRS has started examining your returns or opened a criminal investigation, so getting in before the IRS calls is the whole point.
