Tax Exemptions and Credits for US Citizens Living Abroad

U.S. citizens living abroad have three main federal tax breaks that prevent double taxation on the same income: the Foreign Earned Income Exclusion, the Foreign Housing Exclusion, and the Foreign Tax Credit. The exclusion lets you subtract up to $132,900 of foreign wages from your 2026 taxable income.¹ The credit offsets your U.S. tax bill dollar-for-dollar for income tax you paid to a foreign government. The housing exclusion knocks out qualifying rent and utilities above a base amount. Which combination saves you the most depends on where you live and what you earn, and the United States taxes its citizens on worldwide income no matter where they live, so choosing well matters.²

The Foreign Earned Income Exclusion

The FEIE subtracts qualifying foreign earnings from your taxable income before your federal tax is calculated. For 2026, the ceiling is $132,900 per person, adjusted for inflation each year.¹ If both spouses work abroad and each qualifies independently, a couple filing jointly could exclude up to $265,800 combined.

Only earned income counts. That means wages, salaries, bonuses, commissions, and net self-employment profits for work you performed while physically in a foreign country. Dividends, interest, capital gains, rental income, royalties, pensions, and Social Security benefits do not qualify. Neither does pay from the U.S. government for federal civilian or military service abroad. You claim the exclusion on Form 2555, attached to your Form 1040, and report income in U.S. dollars using the exchange rate on the date received. If you only qualify for part of the year, the $132,900 cap is prorated based on your qualifying days.

How You Qualify: Tax Home Plus a Presence Test

Two conditions have to be satisfied together. Your tax home must be in a foreign country, and you must meet either the bona fide residence test or the physical presence test.³

Tax Home

Your tax home is the general area of your main place of business, not necessarily where your family lives. Work in London, and London is your tax home even if your spouse stays in Chicago. The catch: the IRS will not treat your tax home as foreign if your “abode” remains in the United States, meaning the place where your strongest personal, family, and economic ties sit.³ Keeping a furnished home, family, and financial life in the U.S. while working a short contract overseas can sink your eligibility.

Bona Fide Residence Test

You need to be a genuine resident of a foreign country for an uninterrupted period that covers at least one full calendar year, January 1 through December 31.⁴ The IRS looks at the nature and length of your stay, your integration into the community, and your intent. If you tell the foreign government you’re not a resident there for local tax purposes, you generally cannot claim bona fide residence for U.S. tax purposes either.

Physical Presence Test

The alternative test is purely mechanical: be physically present in one or more foreign countries for at least 330 full days during any 12 consecutive months.⁵ A full day is a continuous 24-hour period starting at midnight. The 330 days do not need to be consecutive. Time in international waters or airspace generally counts for neither the U.S. nor a foreign country. This route works best for contractors, digital nomads, and anyone whose assignment doesn’t line up with a calendar year.

The Foreign Housing Exclusion

On top of the FEIE, you can exclude qualifying housing costs above a base threshold. This matters most in expensive cities where rent alone eats a large share of your pay. The housing exclusion is claimed on the same Form 2555.

Qualifying expenses include rent, utilities (other than telephone), insurance, occupancy taxes, and similar costs. The IRS specifically excludes lavish or extravagant expenses, the cost of buying property, furniture purchases, and improvements that increase a property’s value.⁶

The base housing amount is 16% of the FEIE maximum, which comes to $21,264 for a full year in 2026.⁶ Only costs above that base are excludable. The standard cap on eligible expenses is 30% of the FEIE maximum, or $39,870 for 2026, so the typical maximum exclusion works out to $18,606.¹

High-cost cities get higher caps. The IRS publishes an annual notice listing them. Recent limits included $114,300 for Hong Kong, $90,000 for Bermuda, and $65,700 for Paris.⁷ The current year’s Form 2555 instructions carry the full city-by-city list.

The Foreign Tax Credit

The Foreign Tax Credit works differently. Instead of removing income from your U.S. return, it gives you a dollar-for-dollar credit against your U.S. tax bill for income taxes you paid to a foreign government.⁸ You claim it on Form 1116.

The credit only offsets U.S. tax on your foreign-source income, not tax on domestic earnings. If you paid more foreign tax than the U.S. would charge on the same income, the unused portion carries back one year and forward up to ten.⁹ That flexibility helps when your foreign tax rate shifts from year to year.

Choosing Between the FEIE and the FTC

You cannot claim both breaks on the same income. Foreign taxes paid on income you already excluded under the FEIE cannot also generate a credit.¹⁰ You can, however, use the FTC on foreign-source income above your excluded amount.

A rough rule of thumb: in a country with tax rates higher than the U.S., the FTC alone often wipes out your U.S. tax on foreign income, leaving no reason to elect the FEIE. In a low-tax or no-tax country, the FEIE usually wins because there’s little foreign tax to credit. Run the numbers both ways before you decide.

The decision has a lock. Revoking a prior FEIE election starts a mandatory five-year period during which you cannot re-elect the exclusion without IRS approval through a private letter ruling, which costs money and is not guaranteed.¹⁰ If your income, country, or foreign tax rate might change soon, factor that in before switching.

Self-Employment Tax Still Applies

Here is the blind spot that costs freelancers abroad the most. The FEIE reduces income tax. It does nothing for self-employment tax. If you’re self-employed abroad, you owe the combined 15.3% Social Security and Medicare tax on your full net earnings, even if every dollar qualifies for the FEIE.¹¹ The IRS gives the example of a $68,000 net profit fully excluded under the FEIE: self-employment tax is still owed on the full $68,000.

The one exit is a totalization agreement. The U.S. has agreements with roughly 30 countries, including the United Kingdom, Canada, Germany, France, Japan, and Australia, that stop workers from paying Social Security taxes to both countries at once.¹² If you’re covered under the foreign system under such an agreement, you may be exempt from U.S. self-employment tax on that income. No agreement means you pay into both.

Filing Deadlines Abroad

U.S. citizens abroad get an automatic two-month extension, shifting the filing deadline from April 15 to June 15. You qualify if you live outside the U.S. and Puerto Rico and your main place of business is also outside the U.S. on the regular due date.¹³ No special form is required; attach a statement to your return.

Filing Form 4868 extends the deadline to October 15.¹⁴ Neither extension gives you more time to pay. Interest on unpaid tax runs from April 15 regardless of when you file.¹³ If you expect a balance due, estimate and pay by April 15.

Even if the FEIE wipes out your tax, you still have to file when your gross income exceeds the standard filing threshold. For 2026, the standard deduction is $16,100 for single filers and $32,200 for joint filers.¹⁵ The exclusion is claimed on the return itself, so no return means no benefit.

Foreign Account Reporting You Still Owe

The tax breaks above don’t change your reporting obligations, and two separate filings apply to most expats.

If your combined foreign financial accounts topped $10,000 at any point in the year, you file a Report of Foreign Bank and Financial Accounts (FBAR, FinCEN Report 114) electronically through FinCEN’s BSA E-Filing system.¹⁶ It does not travel with your tax return. The deadline is April 15, with an automatic extension to October 15 that requires no request.¹⁷ Penalties for missing the filing are steep, especially for willful violations.

Separately, FATCA requires Form 8938 with your tax return when specified foreign assets exceed higher thresholds. For expats, that’s $200,000 at year-end or $300,000 at any point for single filers, doubling to $400,000 and $600,000 for joint filers.¹⁸ Form 8938 covers more than bank accounts, including foreign stock, partnership interests, and certain foreign retirement accounts. If you cross both thresholds, you file both. One doesn’t replace the other.

What the Federal Breaks Don’t Cover

Two boundaries catch expats who assume the FEIE and FTC handle everything.

The Net Investment Income Tax adds a 3.8% surtax on investment income when modified adjusted gross income exceeds $200,000 single or $250,000 joint. Those thresholds have not been indexed since the tax began in 2013. The FEIE excludes only earned income, so dividends, capital gains, rental income, and interest remain fully exposed. The tax is calculated on Form 8960.

State taxes are a separate problem. Several states keep treating you as a resident after you move overseas and expect a return on your worldwide income. California, New York, Virginia, New Mexico, and South Carolina are among the hardest to leave for tax purposes. Each looks at its own residency factors, including driver’s license, property, bank accounts, and family ties. States without an income tax, such as Florida, Texas, and Nevada, pose no issue. Establishing residence in a no-income-tax state before you leave can be worth real money later.

If You Never Filed While Abroad

The IRS runs streamlined filing compliance procedures for expats whose failure to file was not willful. You certify that your noncompliance came from negligence, honest mistake, or a good-faith misunderstanding of the rules.¹⁹

Under the streamlined foreign offshore procedures, you file three years of back tax returns and six years of FBARs. For taxpayers who lived outside the U.S. during the relevant period, there is no additional penalty beyond tax and interest owed. Returns come in through the normal process and are not automatically audited, though they remain subject to standard examination.¹⁹ You lose eligibility once the IRS opens an examination or criminal investigation, so acting before contact matters.
