Guam tax return
Guam

Guam has its own tax system that is independent of the tax system of the United States. It has significant differences, but it is based on the tax code of the United States.

Bona Fide Resident of Guam; U.S. Citizen or Resident Alien

If you are a bona fide resident of Guam for the entire tax year, then you must file a tax return with Guam reporting gross income from worldwide sources. If you are also a U.S. citizen or resident alien, you must file a U.S. Tax Return reporting your worldwide income, with the exception of income from Guam. You may also have to file Form 5074 - Allocation of Individual Income Tax to Guam or the Commonwealth of the Northern Mariana Islands - along with your tax return.
