U.S. TERRITORIES and POSSESSIONS
Samoa, Guam, the Commonwealth of the Northern Mariana Islands, the Virgin Islands and Puerto Rico have their own independent tax departments. If you have income from one of these possessions, you may have to file a U.S. tax return only, a possession tax return only, or both returns. This generally depends on whether you are considered a resident of one of the possessions. In some cases, you may have to file a U.S. return, but be able to exclude income earned in a possession from U.S. tax. For more information, see the IRS International Taxpayer page.
