🇬🇺 Moving to Guam: tax, residency and cost of living
Guam is an unincorporated territory of the United States that operates a so-called mirror tax system, whereby the federal Internal Revenue Code applies locally, but tax is paid to Guam through its Department of Revenue and Taxation. Bona fide residents are taxed on worldwide income on a single Guam return. Top rates track the US brackets, with a highest marginal rate of about 37% in 2026, a corporate tax of about 21% and capital gains taxed up to 20%. Residents are US citizens and travel on a US passport. The island is a western Pacific outpost with a strong military presence, high import costs and a humid tropical climate.

Honest trade-offs
- Guam kent hoge kosten van levensonderhoud door afhankelijkheid van invoer, plus tyfoonrisico en grote afstand tot grote centra.
- De spiegelbelasting volgt de federale schijven, met een hoogste marginaal tarief van circa 37%; inwoners worden op hun wereldinkomen belast.
- Amerikaanse belastingverdragen strekken zich doorgaans niet uit tot Guam, wat dubbele heffing voor internationale inwoners kan compliceren.
