Marshall Islands Tax Authority and What It Administers

Meet the Marshall Islands Tax Authority: Who Collects and Administers TaxCopy link to section

The tax authority in Marshall Islands sits inside the Ministry of Finance, Banking and Postal Services, where revenue functions are handled by the Division of Customs, Treasury, Revenue and Taxation and its Revenue and Taxation unit. This body assesses and collects domestic taxes, processes returns, and enforces compliance, while a separate registry handles corporate formation and a separate social security body issues the identifier that serves as a tax number.

For a foreign owner, the practical reality is that an offshore company conducting no business inside the country has almost no direct dealings with this authority, while any firm that hires local staff or earns income from services rendered there does. This article explains who administers tax, what they administer, how you register and file, and the enforcement and reputational points that matter from abroad. It is most relevant to non-resident company owners, investors using the international registry, and the advisers structuring their affairs. Official notices and guidance sit on the Ministry of Finance website.

The Division of Revenue and Taxation and Its Statutory MandateCopy link to section

The Ministry of Finance was established under the Financial Management Act (11 MIRC Chapter 1) as the parent body for all public revenue and fiscal functions. It is organised into four divisions and one satellite office, the Ebeye Finance Office on Kwajalein Atoll, all under the Minister and Secretary of Finance.

Revenue work falls to the Division of Customs, Treasury, Revenue and Taxation. Within it, the Revenue and Taxation function manages assessment and collection of income, business, and property taxes, processes returns, and addresses taxpayer queries.

Taxes that are levied, assessed, and collected flow into the Marshall Islands General Fund, available for appropriation by the Nitijela (parliament). The governing fiscal statute is the Income Tax Act 1989, codified as Title 48 of the Marshall Islands Revised Code.

A Request for Proposal for an Integrated Revenue Administration System (RFP MOF2025-001) was issued in 2025, pointing to active modernisation of revenue infrastructure. An Income Tax (Amendment) Act 2025 was also introduced in the Nitijela, indicating that the legislative base continues to evolve.

What the Tax Authority Actually Administers in the Marshall IslandsCopy link to section

The split that matters for a foreign owner is between entities operating inside the country and offshore companies that do not. The first group faces real domestic taxes; the second is largely outside the net.

For businesses active within the jurisdiction, the Income Tax Act 1989 imposes a Business Gross Receipts Tax: USD 80 per year on the first USD 10,000 of gross revenue, then 3% on any excess. Employment income drives the rest of the domestic system, through a Wage and Salary Tax and social security.

Offshore companies are treated very differently. Under the Business Corporations Act 1990, an entity incorporated through the international registry and conducting no business in the country pays no corporate income tax on income earned outside it.

There is no withholding tax on dividends, interest, royalties, or similar payments to non-residents under the Revenue and Taxation Act 1989. No stamp duty applies to share transfers or other corporate transactions involving offshore companies, and the jurisdiction levies no VAT or goods and services tax.

Two exceptions deserve attention. Income earned by a non-resident from services rendered to clients inside the country is taxed on a gross basis at 10%, collected by withholding at the point of payment. Imports carry duties, with exemptions limited to renewable and alternative energy items.

Economic substance rules apply to relevant entities, requiring them to show genuine activity in the place they claim to be taxed. Compliance is not required where a company proves it is tax-resident abroad, and relevant entities file an annual Economic Substance Report within twelve months of their fiscal year end.

On the treaty front, the country has 13 Tax Information Exchange Agreements, including with Australia, Ireland, the Netherlands, New Zealand, the United States and several Nordic states, but no double tax treaties with any jurisdiction. It has not signed the OECD Multilateral Convention (BEPS MLI).

Registering with the Authority: Steps for Resident and Non-Resident EntitiesCopy link to section

Every business registers with the Registrar of Corporations before it begins operating, receiving a certificate of incorporation as proof of existence. Registration takes roughly five days and costs USD 250, and digital submission means no physical presence is needed; formation can complete within one working day once compliance checks clear.

Articles of Incorporation cover the company name, duration, purpose, registered address, and number of shares, with a foreign investment business licence receipt filed where applicable. Names of officers, directors, and shareholders are not entered in any public registry and remain confidential.

The country issues no Tax Identification Numbers. Instead, the Marshall Islands Social Security Administration issues an Employer Identification Number, which doubles as the tax identifier, and every employer operating there must apply for one.

This is the trigger for foreign companies: if you employ staff working in the country, you are an employer within the jurisdiction and must register with the tax authorities and the social security body. The OECD AEOI note confirms the EIN structure used in place of a conventional TIN.

A non-resident offshore company that conducts no business in the country has a lighter path. It must keep a registered agent, renew its registration annually, and maintain internal records, but it files no financial statements, no tax returns, and undergoes no audit.

E-Services, Filing Portals and Available Digital ChannelsCopy link to section

Digital channels are partial rather than complete. An online portal handles Economic Substance Reports, and the Ministry of Finance operates an AEOI system through which Reporting Financial Institutions submit CRS data, including mandatory nil returns from the 2024 reporting period under the AEOI Regulations 2016 (as amended).

The Ministry's website at mof.gov.mh is the primary official channel for notices, regulations, and CRS guidance, and a 2025 public notice there set out proposed amendments to the AEOI rules. Company formation accepts digital submissions, removing the need to appear in person.

A unified revenue platform is in development through RFP MOF2025-001 but is not yet operational. No dedicated taxpayer self-service portal for income or business taxes, comparable to an IRS Online Account or an HMRC Personal Tax Account, was identified in official sources.

The Filing and Payment Calendar: Deadlines You Need to TrackCopy link to section

Domestic filing runs largely on a quarterly rhythm. The Business Gross Receipts Tax is paid quarterly, and social security and health insurance contributions are likewise quarterly on earnings up to USD 5,000 per quarter.

After registration, a business submits annual financial statements and a return reporting gross revenue, even where no tax is due. Economic Substance Reports are filed within twelve months of the fiscal year end, and Economic Substance status is reported yearly.

For CRS, automatic exchange under the Multilateral Competent Authority Agreement signed on 29 October 2015 began in September 2018 and continues each year, with nil returns mandatory from the 2024 period. Annual Corporation Maintenance Fees, covering registered office, registered agent, and government charges, fall due on the anniversary of incorporation.

Exact calendar dates for domestic quarterly filings and the annual return were not retrievable from official government sources. Your registered agent is the reliable point for confirming the precise due days that apply to your entity.

Assessment, Audit and Enforcement Powers ExplainedCopy link to section

The Revenue and Taxation function holds statutory authority to assess and collect tax and to enforce compliance. Employers must keep accurate payroll records for each worker, covering wages, hours, and tax withheld, and make them available for inspection.

In an audit, the authority may review tax records, financial statements, and supporting documents, and where discrepancies surface, the taxpayer may face adjustments, penalties, or additional tax. The withholding regime carries particular force: an employer who fails to deduct and withhold becomes liable for the full amount, which forms a lien over the employer's entire assets with priority over other claims and liens on real property.

The Income Tax Act also bars any authorised person from accepting work to advise, prepare materials, or audit records with intent to defeat a tax assessed by the government. Enforcement of economic substance, by contrast, has historically been weak: an EU review in 2023 found it insufficient, allowing shell companies to operate without genuine presence, which prompted corrective action.

Economic substance breaches now draw penalties up to USD 50,000 for a first offence and up to USD 100,000 for continued non-compliance, alongside possible dissolution and exchange of information with foreign tax authorities. The U.S. State Department's 2024 Investment Climate Statement nonetheless noted that weak infrastructure and enforcement continue to let revenue slip through the economy.

Penalties, Interest and Dispute Resolution ProceduresCopy link to section

Evasion attracts a penalty of 50% of the tax owed. A non-resident who fails to file or pay faces a restraining order barring participation in court hearings and use of government services, and the Income Tax Act adds a prohibition on practising or appearing before any court, tribunal, or agency, with cancellation of any professional licence to practise in the country.

Economic substance non-compliance carries the tiered penalties already described, escalating to dissolution and disclosure to foreign authorities. These are the sharpest enforcement tools a non-resident is likely to encounter.

On late-payment interest, no specific rate was retrievable from official sources; most small-island systems apply a statutory rate on overdue tax, but the figure here could not be confirmed. No dedicated tax appeals tribunal or statutory objection procedure was identified either; given the mixed US and English common law system, a taxpayer would most plausibly challenge an assessment through the Supreme Court of the Marshall Islands or administrative review with the Secretary of Finance.

Contact Channels, Offices and Practical Access from AbroadCopy link to section

The Ministry of Finance, Banking and Postal Services maintains its website at mof.gov.mh and a postal address at P.O. Box D, Majuro, MH 96960. Its Division of Customs, Treasury, Revenue and Taxation page is the operative point for AEOI and CRS guidance and notices to Reporting Financial Institutions.

Two other bodies matter in practice. The Marshall Islands Social Security Administration is where the EIN, your effective tax identifier, is obtained, and the Registrar of Corporations operates the business registry that handles formation and annual renewal.

In August 2025 the revenue division and the Registrar conducted joint outreach travel on non-resident matters, confirming that these two bodies engage together on offshore compliance. No verified direct telephone number, email, or named contact for the Revenue and Taxation unit was retrievable; from abroad, the website contact form or a licensed registered agent in Majuro is the dependable access route.

What This Means for a Non-Resident Owner or AdviserCopy link to section

The headline is favourable but conditional. A non-resident company that conducts all its business outside the country owes no corporate income tax on foreign-sourced income under the Business Corporations Act 1990, and no withholding tax applies to dividends, interest, or royalties paid to non-residents.

That outcome is not automatic. The company must prove tax residency elsewhere with a taxpayer identification number, a taxpayer certificate, and tax payment receipts, and it must keep up annual economic substance reporting; pure shell structures without genuine substance no longer hold up, with penalties reaching USD 100,000 and the risk of dissolution.

Transparency obligations are live. The country signed the CRS Multilateral Competent Authority Agreement on 29 October 2015 and has exchanged financial account data annually since September 2018, so information held in local institutions reaches partner jurisdictions.

Two points sharpen the picture for advisers. There is no FATCA Intergovernmental Agreement, so local financial institutions handle FATCA through direct IRS registration and a GIIN, and a GIIN alone does not satisfy CRS obligations. The absence of the BEPS MLI is a material flag for any structure leaning on the 13 information exchange agreements, since the country has opted out of multilateral anti-treaty-shopping measures.

Looking ahead, reform proposals under government consideration in a 2024 policy paper include a 10% consumption tax, a wage tax with a USD 4,160 deduction, and replacement of the gross receipts tax with a 20% business profits tax for larger firms. None of this is enacted, but it would reshape the domestic environment for any future local operations.

ConclusionCopy link to section

For a foreign owner running an offshore company with no local activity, the tax authority in Marshall Islands is mostly a body you keep at a distance, while still meeting annual substance reporting and proving residency elsewhere. The moment you hire staff or earn service income inside the country, you become an employer with real registration, withholding, and quarterly filing duties. Transparency commitments under CRS, the clean EU and FATF standing, and the missing BEPS MLI together define the compliance and reputational frame you work within. Treat the substance and residency-proof requirements as ongoing obligations, not one-time formalities, and the structure remains sound.
