Tax residency in Northern Mariana Islands

How to become a tax resident — and how hard it is to leave.

How to become a tax resident

Typically after 183+ days of presence in a year — or any of:

• Physically present in the CNMI for at least 183 days during the tax year
• Physically present in the CNMI for at least 549 days during the current and 2 preceding tax years, with at least 60 days in each of the 3 years
• Present in the United States for no more than 90 days during the tax year while otherwise resident in the CNMI
• Present in the CNMI for more days in the tax year than in the United States and U.S. earned income not greater than $3,000
• No significant connection to the United States (for example, no permanent home, voter registration, spouse or minor child in the United States)
• Tax home not outside the CNMI during the tax year
• No closer connection to the United States or a foreign country than to the CNMI during the tax year

There is no separate residency- or citizenship-by-investment or nomad visa for the Northern Mariana Islands; as a U.S. territory, long‑term residence for a foreign individual generally requires qualifying under standard U.S. immigration routes (e.g., family, employment, or investor visas like EB‑5) and then choosing to live in the CNMI.

Ending CNMI tax residence is mainly a matter of failing the bona fide residence tests (presence, tax home, closer connection), but IRS Form 8898 reporting is required when beginning or ending bona fide residence, which makes the exit somewhat more involved procedurally.

“Bona fide residents may be citizens, resident aliens or nonresident aliens of the U.S. In general, you are a bona fide resident of a U.S. Territory, if during the tax year, you: Meet the Presence Test, - Present 183 days (or more) in the U.S. territory during the tax year, or Present 549 days (or more) in the U.S. territory during the tax year AND 2 immediately preceding tax years, with a minimum of 60 days presence in the U.S. territory in each of these 3 years, or Present no more than 90 days in the U.S. during the tax year, or Present in the U.S. territory for more days in tax year than in the U.S. AND U.S. earned income is not greater than $3,000, or No significant connection to the U.S. (e.g., no permanent home, voter registration, spouse or minor child in the U.S.). Do not have a tax home outside the U.S. territory during the tax year, and Do not have a closer connection to the U.S. or a foreign country than to the U.S. territory during the tax year. IRC 937 also establishes the filing requirement for Form 8898, Statement for Individuals Who Begin or End Bona Fide Residence in a U.S. Possession, for individuals who became or ceased to be a bona fide resident of a U.S. Territory.” — Internal Revenue Service (IRS) / Commonwealth of the Northern Mariana Islands Division of Revenue and Taxation
