Key Takeaways
- The Marshall Islands levies a wage and salary tax on employment and self-employment income, with rules that determine how residents, non-residents, and foreign workers are taxed.
- Liability depends on residence status, and a special rate applies to U.S. contractor personnel working in the jurisdiction.
- Workers should be aware of filing obligations, withholding at source, payment deadlines, and the penalties that apply for non-compliance or late payment.
- Available allowances, exemptions, and deductions can affect taxable income, and the wage and salary tax may be subject to future changes.
Personal Income Tax in the Marshall Islands: An Introduction to the Wage and Salary Tax
Personal income tax in the Marshall Islands takes a narrow form. The country levies no broad-based income tax; instead, it taxes employment earnings through the Wage and Salary Tax (WST), withheld at source by employers under the Income Tax Act 1989. For a foreign owner weighing where to base staff, the practical takeaway is direct: only wages, salaries, and bonuses earned within the country fall within scope.
Capital gains, dividends, interest, and any income sourced abroad sit outside the WST entirely. This article explains who is liable, the applicable rates and bands, what counts as taxable, and how employers withhold, file, and remit.
It is most relevant to foreign-owned businesses that intend to employ people locally, and to advisers structuring payroll for staff working in this Pacific jurisdiction.
Legal Basis: The Income Tax Act 1989 and Its Recent Amendments
The governing instrument is the RMI Income Tax Act 1989, originally enacted as P.L. 1989-50 and codified in Chapter 1 of Title 48 of the Marshall Islands Revised Code. It establishes the WST and, critically for employers, deems all tax withheld to be held in trust for the Government until remitted to the Secretary of Finance.
Reform has come in stages. A Phase 1 revision of personal income tax rates and thresholds was legislated in October 2024, and the Nitijela (the national parliament) passed Bill No. 103, P.L. 2026-68 on 16 March 2026 to further amend the taxation of wages and salaries.
A second, deeper reform stage is foreseen for October 2026, expected to introduce a VAT and a profit tax. Those measures fall outside personal income tax, but they signal that the wider framework around employment taxation remains in motion.
Monetary allowances and certain procedural details are set by regulation and revised when the parliament amends the Act. Verify specific figures against the enrolled legislation before relying on them.

Who Is Liable: Residents, Non-Residents, and Foreign Workers
Any business employing individuals within the country must operate WST, regardless of where the business is owned. The obligation attaches to the employer, so a foreign-owned entity hiring local staff carries the same withholding duties as a domestic firm.
Expatriate workers are not exempt as a class. Those working outside the Kwajalein base are taxed at the same progressive rates as resident workers, with no general carve-out for foreign nationals.
The territorial limit is the point that matters most to non-residents. No personal income tax is imposed, on residents or non-residents alike, for income earned outside the country. Residency definitions are addressed in a separate article and are not repeated here.
Wage and Salary Tax Rates and Income Bands
The rate structure under P.L. 2026-68, passed on 16 March 2026, is progressive but compact. Two brackets apply to annual employment earnings, and a low-income exemption removes the smallest earners from tax altogether.
| Annual wages and salaries | Rate |
|---|---|
| USD 8,320 or less | Exempt |
| First USD 10,400 | 8% |
| Amount above USD 10,400 | 12% |
The 8% band equates to roughly USD 200 weekly or about USD 867 monthly. Employers do not wait for a year-end calculation; instead, they annualise each pay period's wage to identify the correct bracket, then withhold accordingly.
This represents a reduction at the top. The previously legislated structure carried a 16% top rate, which an IMF mission flagged in a report issued February 2025 before the March 2026 amendment brought the ceiling down to 12%.

The Special 5% Rate for U.S. Contractor Personnel
A flat 5% rate applies to U.S. contractor personnel. P.L. 2026-68 sets this reduced individual income tax rate specifically for wages and salaries of those workers at the Kwajalein base, the U.S. Army garrison known as USAG-KA.
The distinction is geographic. Expatriates working outside Kwajalein face the standard progressive rates, while those inside the base qualify for the 5% treatment and, in practice, do not file returns through the social security administration. Confirm the precise statutory wording against the enrolled text of the 2026 amendment, as the governing section was not retrievable in full during research.
What Counts as Taxable Income: Employment Earnings and Self-Employment Income
The WST reaches employment income only: wages, salaries, and bonuses. For residents, most other personal income, including investment returns and rental receipts, is generally not taxed under this regime, and foreign-source income of any kind remains untaxed.
That exclusion is broad. Capital gains, dividends, and interest do not attract personal income tax, whether the recipient is resident or non-resident.
Self-employment and business income sit in a different system. Local business operations are subject to the Business Gross Receipts Tax, charged at USD 80 on the first USD 10,000 of revenue and 3% on revenue above that, rather than to wage withholding.
- Public sources do not confirm whether self-employed persons pay WST on their own drawings. The general principle is that they fall under the gross receipts regime rather than the wage and salary withholding system.
The Act also contains a provision titled "Individual to file return of earned income," which signals a residual filing duty where withholding has not fully captured a person's earned income.

Personal Allowances, Exemptions, and Deductions for Individuals
Allowances reduce the wage base before WST is computed. The principal relief is a personal exemption for the employee, with the possibility of further allowances for dependants, claimed against gross income.
The clearest threshold is the full exemption for workers earning USD 8,320 or less annually, below which no WST is due. Above that line, the bracketed rates apply to the wage as annualised by the employer.
Two structural points affect the base. Employee social security contributions are not normally deductible when calculating taxable income, and housing allowances have been excluded from the WST base, a treatment the IMF recommended reviewing to widen the labour tax base.
The exact dollar values of the personal exemption and dependant allowances under the post-2024 and post-2026 law were not retrievable from public sources. These amounts are set by regulation and can change when the Act is amended.
A 2024 policy note prepared by Graduate School USA proposed an initial tax-free deduction of USD 4,160 for all wage earners, and the IMF separately recommended a universal tax-free allowance financed by higher marginal rates. Both remain proposals rather than enacted law.
Filing Obligations and Individual Returns of Earned Income
For most employees, there is no separate annual return. Employers calculate, withhold, and remit WST each pay period, so the day-to-day compliance burden rests with the business, not the worker.
The Act does require employers to file a return covering tax on wages and salaries. It also preserves an individual duty, "Individual to file return of earned income," for cases where withholding at source has not fully covered a person's earned income.
Registration runs through the social security administration, MISSA, rather than a tax bureau. The country does not issue Tax Identification Numbers; it relies on Employer Identification Numbers (EINs) to register both employers and employees, a structure outlined in the OECD TIN guidance.
Hiring even a single resident employee triggers the need for an EIN, obtained from MISSA for a USD 20 application fee for corporations. Specific individual return form numbers and filing dates were not retrievable from public sources; the individual obligation is secondary to employer withholding.
Payment, Withholding at Source, and Deadlines
Withholding happens with every paycheck, but remittance to the Government is quarterly. Employers send the withheld tax to the Ministry of Finance after each quarter closes.
The deadline is tight: all withholdings and contributions must be remitted within ten days after each quarter-end, meaning within 10 days of 31 March, 30 June, 30 September, and 31 December. At year-end, employers issue wage statements to staff and submit reports to the authorities.
The trust-fund character of these sums carries real exposure. Tax withheld is held in trust for the Government, and an employer that fails to withhold or pay over becomes directly liable, with the unpaid amount forming a lien over the employer's entire assets that ranks ahead of other claims.
Penalties for Non-Compliance and Late Payment
Non-compliance carries both criminal and civil consequences. On conviction, a person or business may face a fine not exceeding USD 1,000, and a natural person may face imprisonment, alongside any civil penalties the Act provides.
The financial risk for employers is the more pressing concern. An employer who fails to withhold and remit becomes personally liable for the tax, and that liability attaches as a lien over all of the employer's assets with priority over other creditors.
Late payment also draws interest on the unpaid amount and further fines. Exact interest percentages and the civil penalty schedule were not retrievable in full; confirm them against the enrolled text of the Act.
Outlook: Future Changes to the Wage and Salary Tax
Reform is unfolding in two phases. Phase 1, covering personal income tax rates and thresholds, was legislated in October 2024, and Phase 2, foreseen for October 2026, is expected to add a VAT and a profit tax that sit outside the WST.
The March 2026 amendment marks the most recent change to wage and salary rates, lowering the top band from the previously legislated 16% to 12%. An IMF technical report had earlier modelled a revenue-neutral package raising the top rate to 20% with a universal tax-free allowance, and recommended indexing thresholds to inflation.
Policy direction points toward lower labour taxes. The administration that took office in January 2024 has stated an aim to cut income tax and to launch a Universal Basic Income program funded under the 2023 Amended Compact of Free Association.
For a foreign employer, the planning point is that rates, thresholds, and the broader tax mix are likely to keep shifting. Build payroll on the current bands while monitoring the October 2026 stage.
Conclusion
For a foreign business owner weighing Marshall Islands as a place to incorporate or deploy staff, the single factor that cuts through everything else is residence classification. How the jurisdiction categorizes each worker determines tax exposure, withholding duties, and filing obligations more than any other variable covered in this article. Getting that classification right before contracts are signed is not an administrative detail; it is the structural decision that shapes every payroll and compliance obligation that follows.
Future changes to the wage and salary tax mean the current rules should be confirmed against the latest amendments before any workforce or incorporation plan is finalized.

Frequently Asked Questions
No. The country imposes no personal income tax on foreign-source income for residents or non-residents, and that exclusion extends to capital gains, dividends, and interest. Only employment earnings arising within the country fall under the Wage and Salary Tax.
Under P.L. 2026-68, passed on 16 March 2026, the first USD 10,400 of annual wages and salaries is taxed at 8%, and the amount above that at 12%. Workers earning USD 8,320 or less per year are fully exempt.
In most cases, yes. Expatriates working outside the Kwajalein base are taxed at the standard progressive rates with no general exemption. The exception is U.S. contractor personnel at the Kwajalein base, who are subject to a flat 5% rate.
Usually not. Employers calculate and withhold WST each pay period and remit it to the Ministry of Finance, so most employees have no separate filing duty. The Act does preserve an individual obligation to file a return of earned income where withholding has not fully covered that income.
Remittance is quarterly. Employers must pay over withheld amounts within ten days after each quarter-end, that is, within 10 days of 31 March, 30 June, 30 September, and 31 December.
The employer becomes personally liable for the tax, and the unpaid amount forms a lien over the employer's entire assets, ranking ahead of other creditors. Late payment also attracts interest and further fines, and offenses can carry a fine of up to USD 1,000 or, for a natural person, imprisonment.
