Tax System Overview

Guam, as a territory of the United States, follows a territorial tax system, where only income earned within Guam is subject to taxation.

To be considered a resident for tax purposes, an individual must have been present in Guam for at least 183 days in the tax year, or have a permanent home in Guam and spend at least some time in Guam during the tax year.

The tax system in Guam is designed to be relatively simple and straightforward, with a focus on encouraging business and investment in the territory. The government of Guam offers various incentives and tax breaks to businesses and individuals, particularly in the tourism and manufacturing sectors. These incentives can include reduced tax rates, tax credits, and other benefits, making Guam an attractive location for businesses and individuals looking to invest or relocate.
