US Tax Returns for Americans Living Abroad

US citizens and green card holders generally must file when worldwide gross income meets the filing threshold, even with no US-source income or when an exclusion removes the tax. Foreign pay can be taxed, but eligible workers may claim the foreign earned income exclusion or a foreign tax credit. Self-employed workers may still owe US self-employment tax.

Do I have to file if I have little or no US income?

US citizens and green card holders living abroad generally use the same federal filing tests as people living in the US. Count worldwide gross income before any foreign earned income or housing exclusion; having no US-source income does not remove a filing requirement. If you live in Canada, see Americans living in Canada for the two-country filing sequence (IRS: Publication 54).

The general filing threshold depends on filing status, age and income. If your spouse is not a US resident, check married to a nonresident before choosing a filing status. A separate rule requires a return if net self-employment earnings reach $400, even when gross income is below the usual threshold. If your income falls below the applicable tests, you may still file to claim a refund. The foreign earned income exclusion is claimed on a filed return, usually with Form 2555; it does not make qualifying income disappear from the filing test (IRS: Publication 54; IRS: figuring the exclusion).

When is my return due?

An eligible person abroad gets an automatic two-month extension to file and pay without a late-payment penalty, but interest on unpaid tax runs from the regular due date. For a calendar-year return, these are the usual dates; a weekend or legal holiday can move a deadline (IRS: Publication 54).

DateWhat it means
April 15Regular filing date and the date from which interest runs on unpaid tax.
June 15Automatic filing and payment date if your tax home and abode are outside the US and Puerto Rico on the regular due date, or you are on military or naval duty outside those places. Attach a statement explaining eligibility to the return.
October 15Additional filing date if you request it on Form 4868 by the June filing date; check its out-of-country box.
December 15Possible further filing date if you are out of the country and send the IRS a letter by October 15 explaining why you need more time. This extension is discretionary and unavailable if you have an approved Form 2350 extension.
Date approved on Form 2350A special extension if you need more time to meet the residence or presence test for Form 2555, generally until 30 days after you expect to qualify. Apply by your otherwise applicable filing date.

Form 2350 delays filing while you complete a qualification period; it does not delay payment or guarantee that you will meet the test (IRS: Publication 54; IRS: Form 2350). Keep your estimated tax calculation even if you extend.

Is foreign income taxed by the US?

US citizens and resident aliens report taxable income from worldwide sources. Foreign wages, freelance income, interest, dividends, rent and gains can therefore enter a US return; a foreign earned income exclusion or foreign tax credit may reduce income tax if its conditions are met (IRS: U.S. citizens and resident aliens abroad).

For pay from work, the source is generally where you physically perform the services, regardless of your employer's address or where payment lands. Split pay for US and foreign workdays if you work in both places. Foreign investment income is still reportable, but it is not foreign earned income for the exclusion (IRS: what is foreign earned income).

Who qualifies for the foreign earned income exclusion?

You need foreign earned income, a tax home in a foreign country, and either the bona fide residence test or the physical presence test. Your tax home is generally the area where you mainly work, not your mailing address. A US home does not automatically prevent a foreign tax home, but stronger family, economic and personal ties in the US may do so (IRS: tax home in a foreign country).

TestMain conditionWhat commonly changes the answer
Bona fide residenceA US citizen resides in a foreign country or countries for an uninterrupted period that includes an entire tax year. A resident alien can use this test only if also a citizen or national of a country with a US income tax treaty.Residence depends on facts, including the nature and intended length of the stay. Brief trips away need not end residence.
Physical presenceA US citizen or resident alien is in foreign countries for at least 330 full days in any 12 consecutive months that overlap the tax year.A full day runs midnight to midnight. US days and time over international waters generally do not count.

The residence test is not satisfied merely because you spent a calendar year abroad; the IRS examines the whole situation. The presence test counts days regardless of why you traveled, but an illness or employer recall does not normally waive missing days. Forced departure because of war, civil unrest or similar conditions can qualify for a waiver if the country and departure date are on the IRS list and you otherwise meet its conditions (IRS: bona fide residence; IRS: physical presence; IRS: exceptions to the time tests). Keep a dated travel record and evidence of where you lived and worked.

How much can I exclude, and which pay counts?

The maximum foreign earned income exclusion is $132,900 per qualifying person for a full qualifying year; a partial qualifying year reduces the limit. Claim it with Form 2555, after calculating any foreign housing exclusion. Each claimant completes a separate Form 2555 with the signed return; both spouses sign a joint return. Generally make the election by the filing deadline, including extensions, though amended and late returns can qualify under IRS rules (IRS: figuring the exclusion; IRS: choosing the exclusion).

IncomeForeign earned income for this purpose?
Wages, salary, professional fees and qualifying self-employment income for services performed in a foreign countryGenerally yes, if earned during the qualifying period.
Pay for work physically performed in the USNo, even if a foreign employer pays it.
Interest, dividends, capital gains, pensions and Social Security benefitsNo; these are not pay for current personal services abroad.
Rent from property abroadUsually not pay for services; some rental activity may qualify in part. See property abroad for return treatment.
Pay as a US government employeeNo, even when the work is abroad.

The exclusion covers income tax, not every tax. It also does not lower the tax bracket used on income that remains taxable. For a business whose income comes from both your services and invested capital, only the part treated as pay for your services may qualify; Form 2555 has allocation rules (IRS: foreign earned income exclusion; Form 2555 instructions).

What is the foreign housing exclusion or deduction?

A qualifying worker may exclude or deduct eligible foreign housing costs above a base amount, subject to a location-based limit. Ordinary taxable salary can support the housing exclusion; a separate employer allowance is not required. Self-employment earnings can support a housing deduction. If you have both, the housing amount may be split (IRS: Publication 54).

For a full qualifying year, the base housing amount is $21,264 and the standard cap on expenses counted is $39,870. Some locations have different caps in the IRS housing notice; a shorter qualifying period changes the calculation. These are limits on the calculation, not amounts automatically excluded.

Reasonable rent, utilities other than phone charges, insurance and certain lease or repair costs may count. Buying a home, mortgage principal, purchased furniture and meals do not. Keep the lease, payment records and employer pay details. Form 2555 figures any housing exclusion before the earned income exclusion. A self-employed person's housing deduction is limited to foreign earned income left after both exclusions; an unused amount may carry to the next year only (IRS: Publication 54; Form 2555 instructions).

Should I use the exclusion or the foreign tax credit?

Compare both on the complete return before electing the foreign earned income exclusion. The foreign tax credit, generally claimed on Form 1116, can reduce US income tax on income taxed by another country; the exclusion removes eligible foreign work income from US taxable income. Test the exclusion when foreign income tax on your pay is low or absent; test the credit when you pay substantial foreign income tax or the additional child tax credit matters. Neither result follows from the foreign tax bill alone (IRS: foreign tax credit; IRS: choosing the exclusion).

FactorForeign earned income exclusionForeign tax credit
Income it addressesQualifying pay for services abroad, subject to the annual limit.Eligible foreign income taxes on income also subject to US income tax, subject to credit limits.
Foreign tax on excluded payCannot also be credited or deducted.May be credited only on income that is not excluded.
Effect on other US taxDoes not reduce self-employment tax; remaining income is taxed using rates calculated with excluded income included.Reduces eligible US income tax, but not self-employment tax.
Family creditsEither exclusion or the housing deduction prevents the additional child tax credit and earned income credit (Form 2555 instructions).Does not itself impose those exclusion rules.

The exclusion and credit can coexist for different income, such as foreign taxes on wages above the excluded amount. Each exclusion election continues until revoked. To revoke, attach a statement naming the election to the return or amended return for the first year you stop claiming it; claiming a credit for tax on income you could exclude also revokes it. Choosing the same exclusion again within five tax years requires IRS approval (IRS: Publication 54). Gather foreign tax returns, pay statements and details of any prior Form 2555 election before choosing.

Do I still owe US self-employment tax abroad?

Foreign earned income excluded from income tax still counts when calculating US self-employment tax. A self-employed US citizen or resident generally files if net self-employment earnings reach $400 and uses Schedule SE, unless an applicable Social Security agreement assigns coverage elsewhere (IRS: Publication 54).

An agreement may assign your work to one country's system, but its result depends on the country and work pattern. If it exempts you from US self-employment tax, obtain the foreign certificate of coverage and attach a copy to your US return as proof (Social Security Administration: international agreements). Keep foreign social insurance records and the certificate with your tax records.

Does my old state still tax me?

Moving abroad does not by itself settle state residency or state-source income. Each state has its own rules; check the state where you lived and any state where you still work, own rental property or receive other state-source income.

California shows why the separate check matters. Its residency test depends on all the facts, including whether an absence is temporary or transitory. Some people leaving under an employment-related contract qualify for a California nonresident safe harbor; check its absence, visit, income and purpose conditions. A California resident is generally taxed on worldwide income, while a nonresident may owe tax on California-source income. California does not allow the federal foreign earned income exclusion, housing exclusion or housing deduction; make the relevant California adjustment when applicable (California FTB: resident status; California FTB: federal and state adjustments). Keep records of your move, home, family ties and workdays by state.

What does a green card holder abroad file?

A green card holder generally remains a US resident for tax and files Form 1040 on worldwide income while that status continues. Living abroad alone does not end the duty. A green card holder who is not a citizen or national of a treaty country cannot use bona fide residence for Form 2555, but may qualify through physical presence (IRS: international individual tax questions; IRS: foreign earned income exclusion).

A green card holder who qualifies for and claims residence in another country under a treaty's tie-breaker files Form 1040-NR; Form 8833 may also be required. For a long-term resident, that choice can trigger US expatriation rules; see exit tax for green card holders before making it (IRS: international individual tax questions).

Example

Illustrative only; all amounts are US dollars. A US citizen lives and works abroad all year, has a foreign tax home and meets the physical presence test. She receives $100,000 in wages for work performed there and $2,000 of bank interest, with no housing claim or deductions tied to the wages. She reports $102,000 before the exclusion. On Form 2555, her qualifying wages are $100,000, below the annual limit, so she can exclude all $100,000; the $2,000 of interest remains reportable before deductions. The exclusion alone does not establish whether she owes US income tax.
