What Is an Expatriate? Definition, U.S. Taxes, and Exit Rules

An expatriate is a person who lives outside the country where they hold citizenship without giving up that citizenship. For a U.S. citizen, being an expatriate has a specific financial meaning: the federal government taxes its citizens on worldwide income no matter where they live, and it requires them to report foreign bank accounts and assets under threat of steep penalties. Understanding what an expatriate is starts with the definition, but the more useful question is what the label actually obliges you to do.

Expatriate vs. Immigrant

The word comes from Latin roots meaning “out of one’s country.” In everyday use, an expatriate is a citizen who has moved to another country while keeping their original nationality. The distinction from an immigrant is a matter of direction. An immigrant is defined by arriving somewhere new with the intent to stay permanently. An expatriate is defined by leaving home. Most expatriates keep their original passport, remain on their home country’s consular rolls, and hold temporary status in the host country under work permits or residency visas rather than a naturalization track.

That distinction is not academic. It decides which government retains primary jurisdiction over your tax and civic obligations. A U.S. expatriate living in Germany still owes the IRS an annual accounting of every dollar earned worldwide. An immigrant who becomes a German citizen and formally renounces U.S. citizenship does not. The legal tie of citizenship, not where you sleep at night, drives everything below.

Why People Live Abroad

Corporate transfers are the most visible driver. Multinational companies routinely send employees to foreign offices for two- to five-year assignments, usually with housing allowances, relocation packages, and employer-sponsored visas. Retirement abroad is another common path, pulled by lower costs of living, warmer climates, and affordable healthcare in parts of Latin America, Southeast Asia, and southern Europe. Family reunification, joining a spouse or close relative already established elsewhere, accounts for many of the rest.

You Still File a U.S. Tax Return

The United States is one of only two countries that tax citizens on worldwide income regardless of where they live. If you are a U.S. citizen or resident alien, you file income tax returns and pay estimated tax the same way as someone living in Ohio.¹ Foreign salary, rental income, investment gains, and self-employment profit all appear on Form 1040.

The standard deadline is April 15. Expatriates whose main home and place of work are both outside the United States get an automatic two-month extension to June 15, claimed by attaching a statement to the return. Interest on unpaid tax still runs from April 15, so the extension covers paperwork, not payment.² You can request a further extension to October 15 by filing Form 4868.

The Foreign Earned Income Exclusion

The main tool for reducing double taxation on wages is the Foreign Earned Income Exclusion under IRC Section 911. For the 2026 tax year, qualifying expatriates can exclude up to $132,900 of foreign earned income from U.S. taxable income.³ The figure is adjusted annually for inflation.⁴

Living overseas is not enough on its own. You must pass one of two tests:

The bona fide residence test: you have been a genuine resident of a foreign country for an entire tax year. The IRS weighs the length of your stay, your ties to the local community, and whether you intend to remain indefinitely.
The physical presence test: you have been physically present in a foreign country for at least 330 full days during any 12-month period. A full day means midnight to midnight, so travel days that route through the U.S. do not count.⁵

On top of the income exclusion, you can elect the foreign housing exclusion for qualifying housing expenses abroad. For 2026, the housing exclusion cap is $39,870, though the actual limit varies by location and by the number of qualifying days in the year.³

The Foreign Tax Credit

If you pay income taxes to a foreign government, the Foreign Tax Credit offsets your U.S. tax bill dollar-for-dollar by the amount of foreign tax paid. You claim it on Form 1116. For expatriates in high-tax countries like France or Japan, the credit often wipes out U.S. liability more effectively than the exclusion.⁶

You cannot use both tools on the same income. If you exclude income under Section 911, you cannot also credit taxes paid on that excluded income. Which route saves more depends on your tax rate abroad, the type of income, and whether your foreign earnings exceed the exclusion cap. As a rule of thumb, the credit tends to win when the foreign tax rate exceeds the U.S. rate, because the exclusion only shelters earned income while the credit covers taxes on investment income too.

Reporting Foreign Accounts

FBAR (FinCEN Form 114)

If the combined value of your foreign financial accounts exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts.⁷ It is a separate filing from your tax return, submitted electronically to the Financial Crimes Enforcement Network. The $10,000 threshold is cumulative across all accounts, so three accounts that briefly total $10,001 on one day in July all must be reported.⁸

Penalties are steep. The inflation-adjusted maximum for a non-willful violation is $16,536 per account, per year.⁹ A willful failure can cost 50 percent of the highest account balance or $100,000 (adjusted for inflation), whichever is greater. Multiple accounts across multiple years stack.

FATCA (Form 8938)

The Foreign Account Tax Compliance Act adds a second layer through Form 8938, filed with your tax return. Thresholds are higher than the FBAR. Single expatriates living abroad file if the total value of their foreign financial assets exceeds $200,000 on the last day of the tax year or $300,000 at any time during the year. Married couples filing jointly face thresholds of $400,000 and $600,000.¹⁰ Failing to file triggers a $10,000 penalty, and if you still have not filed 90 days after an IRS notice, an additional $10,000 accrues every 30 days up to a $50,000 maximum.¹¹

Foreign banks also report American account holders directly to the IRS under FATCA. The agency often knows what you hold before you file.

If You Are Already Behind

Many expatriates discover their filing obligations years after moving abroad. The IRS offers the Streamlined Foreign Offshore Procedures for exactly this situation. If you live outside the United States and your failure to file was non-willful, meaning it stemmed from a genuine misunderstanding of the rules rather than a deliberate choice to evade them, you can file three years of delinquent tax returns and six years of missed FBARs without paying any penalties.¹²

You must certify under penalty of perjury that your noncompliance was non-willful, and you need a valid Social Security number or ITIN. The program is not available if the IRS has already started examining your returns or opened a criminal investigation. For people who genuinely did not know, this is the single most important relief program to know about.

Social Security and State Taxes Still Reach You

U.S. citizens can receive Social Security payments in most foreign countries. Payments cannot go to Cuba or North Korea, and there are restrictions on several former Soviet states including Belarus, Kazakhstan, and Uzbekistan. To prevent double payroll taxation, the United States maintains totalization agreements with about 30 countries, including Canada, the United Kingdom, Germany, France, Japan, Australia, and most of Western Europe.¹³ Under those agreements, you pay into only one country’s system based on where you work and how long the assignment lasts.

State income taxes can follow you overseas too. Most states treat you as a non-resident once you leave, but California, New York, Virginia, South Carolina, and New Mexico are known for aggressively maintaining residency claims based on keeping a home, a driver’s license, or family and financial ties in the state. The burden of proving you have permanently left falls on you. States with no income tax, like Texas, Florida, Wyoming, and Nevada, create no state burden at all. Establishing residency in one of those before leaving can save real money.

Renouncing U.S. Citizenship

Some expatriates decide to sever the tie permanently. Renunciation is a formal legal act governed by 8 U.S.C. 1481, and it cannot be undone. You must appear in person before a consular officer at a U.S. embassy or consulate abroad, sign an oath confirming you understand the consequences, and demonstrate that you are acting voluntarily with the intent to give up your nationality.¹⁴ You cannot renounce by mail, through an attorney, or while physically present in the United States.

The administrative fee for renunciation dropped from $2,350 to $450 effective April 13, 2026, after the State Department concluded the previous fee was prohibitively high.¹⁵ Once the State Department issues a Certificate of Loss of Nationality, you are legally a foreign national.

Before renunciation takes effect for tax purposes, you file Form 8854, the Initial and Annual Expatriation Statement. It requires you to certify under penalty of perjury that you have complied with all U.S. tax obligations for the five years before your expatriation date, covering income tax, employment tax, gift tax, and all information returns. Failing to certify automatically triggers “covered expatriate” status and the exit tax regardless of your net worth or income.¹⁶

The Exit Tax

The exit tax under IRC Section 877A applies to covered expatriates. You are one if you meet any of three tests at the time of renunciation:¹⁷

The net worth test: your net worth is $2 million or more on the day before expatriation.
The income tax test: your average annual net income tax liability for the five years before expatriation exceeds the inflation-adjusted threshold, which is $211,000 for 2026.¹⁸
The certification test: you fail to certify on Form 8854 that you have complied with all federal tax obligations for the prior five years.

Covered expatriates are treated as if they sold all their worldwide property for fair market value the day before expatriating. Any gain above the statutory exclusion (a base of $600,000, adjusted annually for inflation) is taxed in that final year.¹⁷ For someone with significant appreciated assets, a long-held home, a stock portfolio, retirement accounts, the bill can be substantial. Planning with a cross-border tax professional well before renunciation is where large savings live.

After renunciation you need a visa or Visa Waiver Program eligibility to enter the United States, just like any other foreign national.¹⁹ Social Security benefits already earned are generally still payable, since they are based on work history rather than current citizenship, subject to the country-of-residence rules and any applicable totalization agreement.
