If you are a U.S. citizen or a U.S. resident alien living in a foreign country, you are subject to the same U.S. income tax laws that apply to citizens and resident aliens living in the United States. But if you qualify, use Form 2555 to exclude a limited amount of your foreign earned income. Also, use it to claim the housing exclusion or deduction. You cannot exclude or deduct more than your foreign earned income for the tax year.
You may be able to use Form 2555-EZ, Foreign Earned Income Exclusion, if you did not have any self-employment income for the year, your total foreign earned income did not exceed $91,400, you do not have any business or moving expenses, and you do not claim the housing exclusion or deduction. For more details, see Form 2555-EZ and its separate instructions.
Specific rules apply to determine if you are a resident or nonresident alien of the United States. See Pub. 519, U.S. Tax Guide for Aliens, for details.
