This applies to earned income (such as wages and tips) as well as unearned income (such as interest, dividends, capital gains, pensions, rents, and royalties). If you reside outside the United States, you may be able to exclude part or all of your foreign source earned income. For details, see Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad.
