Income Taxes for U.S. Citizens and Resident Aliens Abroad
If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you are in the United States or abroad. Your worldwide income is subject to U.S. income tax, regardless of where you reside.
When to File
If you reside overseas, or are in the military on duty outside the U.S., you are allowed an automatic 2-month extension to file your return until June 15. However, any tax due must be paid by the original return due date (April 15) to avoid interest charges.
If you are unable to file your return by the due date, you can request an additional extension to October 15 by filing Form 4868 (PDF 120 KB) before the return due date. However, any payments made after June 15 would be subject to both interest charges and failure to pay penalties.
Where to File
If you are a U.S. citizen or resident alien (Green Card Holder), and you live in a foreign country or you are a non resident alien, mail your U.S. tax return to:
Department of the Treasury
Internal Revenue Service Center
Austin, TX 73301-0215
Estimated tax payments should be mailed with form 1040-ES to:
Internal Revenue Service
P.O. Box 660406
Dallas, TX 75266-0406
Taxpayer Identification Number
Each taxpayer who files, or is claimed as a dependent on, a U.S. tax return will need a social security number (SSN) or individual taxpayer identification number (ITIN). To obtain a SSN, use form SS-5, Application for a Social Security Card. To get form SS-5, or to find out if you are eligible for a social security card, contact a Social Security Office or visit Social Security International Operations. If you, or your spouse, are not eligible for a SSN, you can obtain an ITIN by filing form W-7 along with appropriate documentation.
You must express the amounts you report on your U.S. tax return in U.S. dollars. If you receive all or part of your income or pay some or all of your expenses in foreign currency, you must translate the foreign currency into U.S. dollars. Taxpayers generally use the yearly average exchange rate to report foreign-earned income that was received regularly throughout the year. However, if you had foreign transactions on specific days, you may also use the exchange rates for those days. Click here for exchange rates. Yearly average currency exchange rates for most countries can be found at Yearly Average Currency Exchange Rates.
