Key Takeaways
- Payroll Tax in the Marshall Islands centers on social security and health fund contributions that apply to employers, employees, and the self-employed.
- Both employers and employees contribute at an 8% social security rate, applied to a defined contribution base subject to exemptions and a quarterly wage cap.
- Foreign-owned businesses must register with MISSA, obtain an employer identification number, and meet withholding, quarterly remittance, and reporting obligations.
- Special arrangements address off-island workers, foreign employers, and independent contractors, with audits and penalties applying to non-compliance.
Understanding Payroll Tax in the Marshall Islands: Social Security and Health Fund Contributions
Payroll tax in the Marshall Islands centres on two mandatory, payroll-linked obligations: Social Security contributions administered by the Marshall Islands Social Security Administration (MISSA), and Health Fund contributions collected on behalf of the Ministry of Health. The Republic of the Marshall Islands (RMI) is not a zero-payroll-tax jurisdiction; any business that employs staff locally must withhold and remit these amounts alongside the Wages and Salary Tax (WST), the separate income tax on employment earnings detailed by MISSA.
These contributions fund retirement pensions, disability and survivor benefits, and the national health programme. All figures are denominated in US dollars, the country's official currency.
This article explains the legal framework, the rates and quarterly caps, who falls within the system, how registration and remittance work, and what the rules mean for a foreign-owned entity hiring on the ground. It is written for non-resident business owners, investors, and their advisers weighing whether to employ staff in the jurisdiction or maintain compliance with an existing local payroll.
The Legal Basis: The Social Security Act of 1990 and MISSA's Mandate
The governing statute is the Social Security Act of 1990 (Public Law 1990-75), which created MISSA and tasked it with administering the national Retirement Fund. That Act replaced earlier 1987 legislation and has since been refined, most notably by the Social Security (Amendment) Act 2017.
The law reaches every employee working in the country, and it expressly extends to off-island employees of employers doing business in the RMI. For a foreign company, this means the obligation can attach to your workers even where part of the work is performed abroad.
A separate measure, the Social Security Health Fund Act of 1991, first established the Health Fund. Administration of that fund was later moved to the Ministry of Health under Public Law 2002-57, with the handover taking effect 1 December 2002.
The consolidated rules sit at 49 of the Marshall Islands Revised Code. MISSA operates as a component unit of the RMI, with collection authority for both the Retirement Fund and, on the Ministry's behalf, the Health Fund.

Who Must Pay: Employers, Employees, and Self-Employed Coverage
The system operates as social insurance covering gainfully employed and self-employed persons. Certain casual workers fall outside it, but most working relationships are captured.
Corporations, government bodies, and other entities that engage workers are treated as employers. As an employer, you deduct the employee share of Social Security and Health Fund contributions through payroll and remit them together with your own matching share.
Self-employed reporting follows its own logic:
- A self-employed person with one or more employees reports on actual wages, or on twice the wages of the highest-paid worker in the quarter, whichever applies.
- Where two self-employed individuals run the same business, total taxable wages are divided by two, and each reports that figure.
- A self-employed person with no employees reports on gross revenue for the quarter.
The government itself contributes as an employer and provides subsidies where needed.
Contribution Rates: The 8% Employee and 8% Employer Social Security Split
Social Security is split evenly. Employees contribute 8% of wages, and every employer matches that with an equal 8%, producing a combined 16% on gross wages.
The 8% employee rate took effect 6 March 2017, up from the previous 7%. The progression over the decades reflects gradual increases:
| Period | Rate |
|---|---|
| Oct 1987 – Jun 1990 | 3% |
| Jul – Sep 1990 | 4% |
| Oct 1990 – Jun 1995 | 5% |
| Jul 1995 – Mar 1997 | 6% |
| Apr 1997 – Dec 2000 | 5% |
| Jan 2001 – 5 Mar 2017 | 7% |
| 6 Mar 2017 onward | 8% |
Self-employed persons pay the combined 16% on 75% of gross covered earnings. Small business employers contribute 16% calculated on twice the salary of their highest-paid employee.
One point matters for net pay calculations: the employee's Social Security contribution is not deductible from gross income when computing taxable income for the Wages and Salary Tax.

The Contribution Base: Taxable Earnings, Exemptions, and the Quarterly Wage Cap
Contributions apply only to the first USD 10,000 of earnings per quarter for Social Security, equivalent to USD 40,000 across a full year. Wages above that quarterly cap attract no further Social Security deductions. The cap was USD 5,000 per quarter before 6 March 2017.
No minimum earnings floor applies, so contributions begin from the first dollar of covered wages. Taxable earnings are defined broadly to include salary, wages, bonuses, tips, stipends, allowances, and fees, whether paid in cash or another form.
Several categories are carved out. The principal exemptions are:
- Payments for accident or sickness, other than ordinary sick leave
- Reimbursement of medical or hospitalisation expenses
- Distributions from a trust or annuity
- Reasonable stipends to volunteers of religious organisations, NGOs, and schools
- Reasonable sitting fees for board members and elected officials
- Earnings exempt under an international agreement
- Reasonable per diem and travel allowances within government rates
- Rental housing allowances up to USD 2,250 per quarter
Specific foreign nationals are also outside the base, including US citizens working for US contractors at the Kwajalein installation under the Compact of Free Association, diplomatic staff, and UN personnel. Wages from sources outside the RMI are likewise excluded.
If a worker's contributions exceed covered earnings across one or more employers, MISSA refunds the excess withheld over the four quarters ending 31 December within 90 days. No refund is issued for amounts under USD 5.00.
The Social Security Health Fund Component and Its Separate Treatment
The Health Fund runs parallel to Social Security but carries its own rate and its own cap. Employees contribute 3.5% of covered earnings, and employers match with 3.5% of covered payroll. That 3.5% rate has applied since 1 January 2002.
The Health Fund cap is lower than the Social Security cap: contributions apply to a maximum of USD 5,000 in gross taxable wages per quarter, with no minimum. Self-employed persons pay 7% on 75% of gross covered income, again capped at USD 5,000 quarterly; small business employers pay 7% on twice the salary of their highest-paid worker.
Although the Ministry of Health administers the fund, MISSA still collects the contributions each quarter on the Ministry's behalf. From 1 January 2003, Health Fund collections no longer appear in MISSA's own accounts, and the Ministry pays MISSA a 3.5% collection fee on the first USD 4 million collected annually.
Two practical limits are worth flagging for budgeting. There are no statutory cash sickness or maternity benefits under the Health Fund. Care is delivered through public hospitals in Majuro and Ebeye, with referrals to the Philippines and Hawaii covered for life-threatening conditions.

Employer Registration with MISSA and Obtaining an Employer Identification Number
Before you begin operations or hire your first resident employee, your firm must obtain an Employer Identification Number (EIN) from MISSA. Each employee must separately apply for a personal Social Security Number. Registration of a new hire must be completed before their first working day, as set out in the MISSA guidance.
Application fees, revised from 1 March 2018, are tiered by entity type:
| Applicant | Fee |
|---|---|
| Corporations | USD 20 |
| Government / private entities | USD 10 |
| Domestic / self-employed workers | USD 5 |
The EIN follows a fixed format: a five-digit number, a dash, then the suffix "04". Failure to register and enrol staff exposes the business to penalties and labour disputes, so the step should be completed early in your setup.
Calculating, Withholding, and Quarterly Remittance Deadlines
Withholding happens with every paycheck, but remittance is quarterly. For each employee you calculate the combined 16% Social Security charge on taxable wages up to the cap, retain the worker's 8% share, and pay the full 16% to MISSA. Health Fund withholding follows the same pattern at 3.5% from each side, capped at USD 5,000 per quarter.
Before paying any employee, you must first withhold the Social Security share and the applicable Wages and Salary Tax. WST is withheld at 8% on annual earnings up to USD 10,400 and 12% above that figure, and is remitted to the Ministry of Finance rather than to MISSA.
Quarterly returns and payments for Social Security and Health Fund are due within ten days of each quarter's close:
| Quarter | Deadline |
|---|---|
| Q1 (Jan–Mar) | 10 April |
| Q2 (Apr–Jun) | 10 July |
| Q3 (Jul–Sep) | 10 October |
| Q4 (Oct–Dec) | 10 January |
Where a deadline lands on a weekend or public holiday, it moves to the next working day. At year-end, employers issue wage statements to employees and file reports with the authorities, and a clear, detailed pay slip must be provided for each pay period.
Compliance, Audits, Penalties, and Reporting Obligations
Accurate payroll records are mandatory. Wage statements, contribution calculations, and remittance receipts must be retained for several years and produced on request during a MISSA or tax authority audit.
A failure to remit has consequences for both sides of the relationship. If you withhold employee contributions but do not pay them over, only the quarters actually remitted are credited to the worker's wage history, which can leave that employee unable to retire even at retirement age.
If MISSA receives only one share, employee or employer, the payment is held as partial and is not applied to any worker's record until both shares arrive in full.
Late payment can trigger penalties, and misclassifying a contractor may lead to fines. Specific monetary penalty rates for late or missing quarterly Social Security and Health Fund filings are not published in the public sources; the general position is that MISSA enforces compliance through its audit powers, disallowance of contributions, and legal action under the governing Act. A separate USD 500 late-filing penalty applies to the annual economic substance declaration (effective 1 November 2023), which is distinct from MISSA returns.
Special Cases: Off-Island Workers, Foreign Employers, and Independent Contractors
The reach of the Social Security Act is wider than a strictly territorial reading might suggest. It taxes the quarterly compensation of every employee working in the country, and explicitly includes off-island employees of employers doing business there.
A foreign company employing individuals in the RMI is treated as an employer within the jurisdiction. You must register with the tax authorities and MISSA and meet every employer obligation, including WST withholding and the matching Social Security contribution, regardless of where the business is headquartered. A foreign firm without a physical presence or registered branch but with staff on the ground can face administrative difficulty meeting these duties.
Expatriate staff are treated the same as local employees, subject to the 8% employee and 8% employer Social Security contributions within the quarterly cap, plus WST. There is no broad exemption for most foreign workers, though Compact-exempt US contractor personnel at Kwajalein, diplomats, and UN staff remain outside the base.
Independent contractors sit differently. The engaging business need not report them, but the contractor is liable for Social Security and Health Fund taxes in their own right under the self-employment rules. Whether someone is an employee or a contractor turns on common law tests of the working relationship.
Two cross-border features may matter to your planning:
- A totalization agreement among the Marshall Islands, Palau, and the Federated States of Micronesia lets citizens who worked across these systems combine credited service to qualify for benefits.
- The country has a limited treaty network, so without a double taxation treaty a foreign worker may face tax in both the RMI and their home country.
What Payroll Tax Means for Companies and Investors in the Marshall Islands
The jurisdiction's zero-tax reputation applies to income earned outside the country. A non-resident domestic entity that conducts no local business is exempt from gross revenue tax, wage tax, and import duties on foreign-source income.
That changes the moment you operate locally. Employing resident staff, leasing premises, or generating domestic revenue brings the entity within a 3% gross revenue tax, WST withholding, and MISSA contributions. The payroll side, however, remains comparatively contained: there is a single main mandatory contribution stream, with no separate deductions for unemployment insurance, family allowances, or workers' compensation.
The quarterly caps put a ceiling on employer cost. Once an employee's wages reach the caps, the most you pay on top of gross wages is fixed:
| Component | Rate | Cap | Maximum cost |
|---|---|---|---|
| Social Security (employer) | 8% | USD 10,000 | USD 800 |
| Health Fund (employer) | 3.5% | USD 5,000 | USD 175 |
| Total | USD 975 |
One further provision affects foreign staff at the end of their careers. Under Public Law 2018-98, non-citizen workers who leave the country permanently on retirement may claim a lump sum equal to 80% of their own contributions, excluding the employer share, provided they meet normal retirement age requirements.
Conclusion
For a foreign business owner, the real question is not whether payroll tax obligations exist in the Marshall Islands but whether the contribution structure and the administrative requirements tied to MISSA registration are budgeted for before the first hire. The quarterly remittance cycle, the employer-side 8% liability, and the distinct treatment of off-island workers and independent contractors are the variables most likely to catch an overseas operator off guard.
Getting the worker classification and registration in place at the outset removes the primary source of audit exposure, making that the single concrete step worth prioritising before payroll runs.

Frequently Asked Questions
An employer matches the employee's 8% Social Security contribution and adds 3.5% to the Health Fund. Social Security applies to the first USD 10,000 of quarterly wages and the Health Fund to the first USD 5,000, capping the employer's additional cost at USD 975 per employee per quarter.
Yes. A foreign company employing individuals in the RMI is treated as an employer within the jurisdiction and must register with MISSA and the tax authorities, irrespective of where it is headquartered. Operating without a physical presence does not remove the obligation, though it can complicate compliance in practice.
Social Security and Health Fund returns and payments are due within ten days after each quarter ends, meaning 10 April, 10 July, 10 October, and 10 January. If a deadline falls on a weekend or public holiday, it shifts to the next working day.
Generally no. Expatriate staff face the same 8% employee and 8% employer Social Security contributions and WST withholding as local employees. The narrow exceptions cover US contractor personnel at the Kwajalein installation under the Compact of Free Association, along with diplomatic and UN staff.
Only the quarters actually paid to MISSA are credited to the employee's wage history. A worker missing credited quarters may be unable to retire even on reaching retirement age, and partial payments covering only one share are not applied to any record until both shares are received.
A non-citizen who departs permanently upon retirement may claim a lump sum equal to 80% of their own contributions under Public Law 2018-98, subject to meeting normal retirement age. The employer's matching share is not included in that refund.
