U.S. Citizens and Resident Aliens Living Abroad To determine whether you must file a return, include in your gross income any income you received abroad, including any income you can exclude under the foreign earned income exclusion.

Residents of Puerto Rico
If you are a U.S. citizen and also a bona fide resident of Puerto Rico, you generally must file a U.S. income tax return for any year in which you meet the income requirements. This is in addition to any legal requirement you may have to file an income tax return with Puerto Rico. If you are a bona fide resident of Puerto Rico for the entire year, your U.S. gross income does not include income from sources within Puerto Rico. It does, however, include any income you received for your services as an employee of the United States or a U.S. agency. If you receive income from Puerto Rican sources that is not subject to U.S. tax, you must reduce your standard deduction. As a result, the amount of income you must have before you are required to file a U.S. income tax return is lower than the applicable amount in Table 1-1 or Table 1-2.
