Tax residency in Northern Mariana Islands
An individual is a tax resident (bona fide resident) of the Northern Mariana Islands for a taxable year only if all three U.S. possession rules are met for that year under the CNMI’s mirror of the Internal Revenue Code: (1) Presence test—satisfied by any one of the following: at least 183 days in the CNMI during the year; or at least 549 days in the CNMI during the current year and the two preceding years with a minimum of 60 days in each year; or no more than 90 days in the United States during the year; or no more than $3,000 of earned income from the United States and more days in the CNMI than in the United States during the year; or no significant connection to the United States (for these rules, “United States” means the 50 states and the District of Columbia and excludes the CNMI); (2) Tax home test—the individual’s tax home (principal place of business, or if none, regular place of abode) is in the CNMI for the entire taxable year; and (3) Closer connection test—the individual has a closer connection to the CNMI than to the United States or any foreign country based on overall facts and circumstances (including the location of permanent home, family, and personal, social, and economic ties). All three conditions must be met; otherwise, the individual is not a CNMI tax resident for that year.
