In the Northern Mariana Islands (CNMI), employers face specific tax obligations for 2025, encompassing federal taxes like FICA, Medicare, and FUTA, alongside CNMI-specific taxes like Chapter 2 (Wage and Salary Tax) and Chapter 7 (Territorial Income Tax).
Federal Taxes
- FICA (Social Security):
- Employee/Employer Tax Rate: 6.20%
- Maximum Taxable Earnings: $176,100
- FICA (Medicare):
- Employee/Employer Tax Rate: 1.45%
- Maximum Taxable Earnings: No limit
- Additional Medicare Tax Withholding (Employee Only) on Wages > $200,000: 0.90%
- FUTA (Federal Unemployment Tax - Employer Only):
- Taxable Wage Base: $7,000
- Tax Rate: 6.00%
- Maximum Credit: 5.40%
- Net Tax Rate: 0.60%
CNMI Taxes
- Chapter 2 Tax (Wage and Salary Tax): This tax is calculated using a percentage based on the annual gross wages with specific withholding tables provided by the CNMI Division of Revenue and Taxation. All employees working in the CNMI are subject to this tax, irrespective of their federal tax exemptions.
- Chapter 7 Tax (Territorial Income Tax): This tax mirrors the U.S. income tax system with its own set of deductions and credits. Employers withhold this tax based on the employee's W-4 form and the federal withholding formula. A non-refundable credit for the Chapter 2 tax withheld is allowed against the Chapter 7 tax liability.
Other Considerations
- Federal employers in the CNMI withhold CNMI income taxes instead of federal income taxes for employees whose regular place of federal employment is in the CNMI. They are also required to file quarterly and annual reports with the CNMI Division of Revenue and Taxation.
- The CNMI has a separate income tax system from the U.S., influenced by both the U.S. Internal Revenue Code and local tax laws. CNMI residents generally file tax returns with the CNMI government, not the IRS, and this applies to all income sources for residents and CNMI-sourced income for non-residents.
- There are specific rebate provisions in the CNMI tax system, including for local taxes on wages and salaries exceeding $50,000 at a 9% rate and on business gross revenue exceeding $750,000 at a 5% rate. These can be claimed as non-refundable credits against CNMI territorial income tax liability.

The Commonwealth of the Northern Mariana Islands (CNMI) offers various tax incentives for businesses and individuals.
Rebates and Abatements
- Tax Rebates: The CNMI offers tax rebates on income tax, ranging from 50% to 90% depending on the income bracket. There's a 90% rebate on the first $20,000 of the "rebate base," 70% on the next $80,000, and 50% on any amount exceeding $100,000. The rebate base is generally calculated as the territorial income tax liability, minus specific deductions.
- Qualifying Certificate (QC) Program: This program provides substantial tax relief through rebates and/or abatements to investors in designated industries. Benefits can reach up to 100% on various CNMI taxes, including income tax, business gross revenue tax, excise tax, and more, for a period of up to 25 years. Factors like job creation, location, and impact on existing industries are considered when determining the benefits granted. Businesses located within designated Tax Free Trade Zones can also qualify for 100% rebates on all taxes.
- Other Rebates: A full 100% income tax rebate is available for Free Trade Zone licensees who employ resident workers and generate income from domestic sources.
Tax Credits
- Individuals with Disabilities Tax Credit: Employers who hire individuals with disabilities may be eligible for a nonrefundable tax credit.
Low-Income Housing Tax Credit (LIHTC)
The Low-Income Housing Tax Credit (LIHTC) program encourages the development of affordable rental housing. Project owners who allocate units for low-income families or individuals can receive federal tax credits. The Northern Marianas Housing Corporation (NMHC) administers this program within the CNMI.
Other Tax Incentives
- No Sales Tax: The CNMI does not impose sales tax.
- No Property Tax: The CNMI does not impose property tax.

CNMI's tax system mirrors the U.S. Internal Revenue Code but with lower rates and unique local taxes like the Business Gross Revenue Tax. As of 2025, income tax constitutes a significant portion of the CNMI's revenue, around 66%. Recent economic developments, such as planned military investments, are expected to influence the economy and tax revenues in the coming years.
