Summary

Special tax rules apply to people who live in Guam, American Samoa, the Northern Mariana Islands, Puerto Rico, or the U.S. Virgin Islands. To count as a "bona fide resident" of one of these possessions, you must be physically present there at least 183 days during the tax year, must not have a tax home outside the possession, and must not have a closer connection to the United States or a foreign country than to the possession. Income is sourced to a possession using rules similar to the ones that decide whether income comes from U.S. sources, but income that is treated as U.S.-source cannot also be treated as possession-source. If you take the position on your U.S. taxes that you became or stopped being a bona fide resident of a possession, you must file a notice of that position with the IRS.
