Hire Employees in the Northern Mariana Islands

The Northern Mariana Islands is a Commonwealth in political union with the United States, using the US dollar and running payroll on US federal machinery.

Two routes exist. A local entity gives direct employment; an Employer of Record removes that setup and acts as legal employer.

The employer side will feel familiar to anyone who has run US payroll. FICA applies, quarterly Form 941 is filed with the IRS, and the FLSA governs wages and overtime.

The tax side will not. The CNMI operates its own income tax system, and it is genuinely unlike either a US state or a standalone jurisdiction, see below.

Employer FICA is 7.65%, exactly as in any other US jurisdiction.

Social Security is 6.2% of wages, applying to both employer and employee, on earnings up to the 2026 wage base limit of US$184,500. The cap is adjusted annually for changes in average national wages.

Medicare is 1.45% from each side with no ceiling. A further 0.9% Additional Medicare Tax applies to employee wages above US$200,000, or US$250,000 for married filing jointly and US$125,000 for married filing separately, so withholding rises to 2.35% for the employee once the threshold is crossed, but there is no employer match on the additional amount.

So employer cost is 7.65% up to the wage base and 1.45% above it.

Break-even rule of thumb: EOR fees begin to exceed the running cost of a CNMI entity somewhere between 12 and 20 employees. See EOR vs Entity.

The CNMI taxes the same wages twice, under two separate chapters of its own code. The IRS describes the system as based partly on the same income tax laws and rates as the US Internal Revenue Code, and partly on local taxes imposed by the CNMI government.

Chapter 2, the Wage and Salary Tax. A local graduated tax withheld from wages.

Chapter 7, the Northern Marianas Territorial Income Tax, or NMTIT. This mirrors the US federal income tax, applying the same progressive schedule: 10% to US$11,600, 12% to 47,150, 22% to 100,525, 24% to 191,950, 32% to 243,725, 35% to 609,350 and 37% above that. Non-residents are taxed on CNMI-source income at the same rates.

Payroll must therefore calculate both, on the same earnings, in the same period.

Watch for sources that say the CNMI has no personal income tax. They are describing the absence of a US state income tax and the fact that no state withholding form is used. The territory has two income taxes of its own, and a payroll built on that misreading would withhold nothing at all.

Gross annual salaries in US dollars. Employer FICA is 7.65% up to the Social Security wage base and 1.45% above it.

Benchmarks below are gross annual salaries in US dollars, which the territory uses as its currency. Employer FICA cost is 7.65% up to the Social Security wage base, then 1.45% Medicare only.

Bi-weekly payroll is common. FICA is remitted federally with quarterly Form 941 filed with the IRS, while the CNMI taxes go to the Division of Revenue and Taxation.

Employers deduct tax each pay period and remit according to CNMI Department of Finance deadlines.

The Department’s own payroll procedures show deductions segregated by type, FICA, Medicare and others, with quarterly compilation of wages and withholdings for the Form 941 return.

Retirement deductions run every pay period through a separate vendor register process, covering the NMI Settlement Fund and 401(a) contributions.

The statutory rebate is the single most important feature of CNMI income tax, and it is substantial.

The territorial income tax mirrors federal rates, but a rebate is then applied on a sliding scale:

Tax of US$20,000 or less: 90% is rebated.

Tax between US$20,001 and US$100,000: US$18,000 plus 70% of the excess over US$20,000.

Tax above US$100,000: US$74,000 plus 50% of the excess over US$100,000.

So an employee with a US$15,000 territorial tax liability sees US$13,500 of it returned. The headline progressive rates therefore overstate the real burden very considerably, particularly at lower and middle incomes.

That matters when comparing net pay against a mainland US offer, the gross-to-net relationship is materially different.

The minimum wage is US$7.25 an hour, inherited from the federal minimum.

The FLSA governs overtime for private sector employees and supersedes local law where it is more beneficial to the employee. It mandates a single minimum overtime premium, and payment of the 150% premium is mandatory in cash for private sector staff.

Certain government employees may instead receive compensatory time off at 1.5 hours per overtime hour, but that route is not available in the private sector.

Contracts should record pay, hours, leave, notice and termination terms.

Set out annual leave expressly. There is no universal statutory requirement for private-sector vacation leave in the CNMI, so whatever the contract says is what applies.

Configure both CNMI taxes alongside FICA before the first run.

The FLSA sets the overtime framework, with a mandatory 150% cash premium for private sector staff.

Because Social Security caps at US$184,500 but Medicare does not, additional pay above the wage base attracts only 1.45% employer cost.

The employee’s Additional Medicare Tax of 0.9% above US$200,000 is withheld but not matched by the employer.

The Northern Mariana Islands observes US federal holidays alongside local observances including Commonwealth Covenant Day in March and Citizenship Day in November.

There is no universal statutory requirement for private-sector annual leave. The amount is determined by employer policy or contractual agreement, with common practice running five to fifteen days a year based on tenure.

That makes leave a competitive lever rather than a compliance floor, and means a contract silent on the point leaves the employee with no entitlement.

Bereavement leave is typically three to five days for immediate family, and is not legally mandated.

Retirement provision runs through the NMI Settlement Fund and 401(a) contributions, processed each pay period. Group health and life insurance is administered separately by the Department of Finance for government staff.

Employment in the CNMI generally follows the at-will doctrine, either party may terminate the relationship at any time, for any lawful reason, unless bound by a contract or collective agreement.

Termination must still comply with anti-discrimination and retaliation laws, which provide the safeguards against wrongful dismissal that a notice regime would otherwise supply.

For foreign workers, employment status and immigration status are linked, so ending employment has consequences beyond the payroll.

The CNMI has its own immigration considerations for foreign workers, and employment is tied to status, confirm the position before committing to a start date.

Bona fide residents of the CNMI file with the CNMI Division of Revenue and Taxation rather than claiming US federal credits. A bona fide resident cannot claim the Earned Income Credit, the Additional Child Tax Credit, the Other Dependent Credit or the American Opportunity Credit on a US Form 1040.

They may be eligible for similar CNMI credits instead, which is a question for the Division rather than the IRS.

The territory uses the US dollar, so there is no conversion in payroll.

Withholding nothing because "there is no income tax" is the most damaging error. Some payroll references state this, meaning only that no US state tax applies. The CNMI has two income taxes of its own.

Calculating only one of the two is the second. Chapter 2 and Chapter 7 both apply to the same wages.

Ignoring the rebate is the third, it returns up to 90% of territorial tax and materially changes net pay comparisons.

Note also that there is no statutory annual leave for private sector staff; that the 0.9% Additional Medicare Tax has no employer match; and that employment is at-will.

Configure FICA, Chapter 2 and Chapter 7 as three separate calculations, and apply the statutory rebate when modelling net pay.

Set annual leave expressly in the contract, since no statutory floor exists, and diarise quarterly Form 941 alongside the CNMI remittance deadlines.

Treat any source claiming the territory has no income tax as describing state tax only.
