Tax residency in United States Minor Outlying Islands
The United States Minor Outlying Islands have no separate personal income tax residency regime; individual residency follows U.S. federal rules. An individual is a U.S. tax resident if a U.S. citizen, or a non‑citizen who either holds lawful permanent resident status at any time during the year (green card test) or meets the substantial presence test: at least 31 days in the United States during the current year and 183 days over the current and two preceding years calculated as all days in the current year, one‑third of the days in the first preceding year, and one‑sixth of the days in the second preceding year, excluding specified exempt‑individual and other excluded days. For this purpose, “United States” means the 50 states and the District of Columbia; presence in the United States Minor Outlying Islands does not count toward substantial presence. A non‑citizen who does not meet either test (and makes no available election) is a nonresident; a closer connection exception may treat an individual as a nonresident if present in the United States for fewer than 183 days in the current year, with a foreign tax home and a closer connection to that country and other statutory conditions met. The bona fide residence rules for U.S. possessions apply only to Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands, not to the United States Minor Outlying Islands. In cases of dual residency, an applicable U.S. income tax treaty may resolve residence using tie‑breaker criteria such as permanent home, center of vital interests, habitual abode, and nationality.
