Tax residency in Northern Mariana Islands

An individual is a CNMI income tax resident only if they are a bona fide resident of the CNMI for the entire taxable year, which requires simultaneously: (1) meeting a presence test satisfied if any one of the following applies—present in the CNMI for at least 183 days during the year; or at least 549 days in the CNMI during the current year and the two preceding years with at least 60 days in each of those years; or at least 60 days in the CNMI during the year and not more than 90 days in the United States (the 50 states and the District of Columbia) during the year; or at least 60 days in the CNMI during the year and no earned income from U.S. sources for the year; or at least 60 days in the CNMI during the year and earned income from CNMI sources exceeding earned income from U.S. sources for the year; (2) having a tax home in the CNMI for the year; and (3) having a closer connection to the CNMI than to the United States or any foreign country, based on ties such as permanent home, family, personal and economic ties, and civic registrations. Individuals who do not meet bona fide residence for the taxable year are nonresidents for CNMI income tax purposes.

Why Tax Residency Rules Matter

Day-Count Thresholds

Most countries trigger tax residency after a set number of days. Cross the threshold and you may owe local taxes.

Permanent Establishment

Repeated business travel to a country can create a permanent establishment, triggering corporate tax obligations.

Stay Compliant

Understanding the rules before you travel helps you avoid unexpected tax liabilities and costly penalties.
