If you live in Sint Maarten and earn income abroad — especially across the Dutch/French border — it is essential to understand your full tax obligations. At CaribTax, we guide individuals and families through the complexities of Sint Maarten's tax system to ensure complete compliance while optimizing every available relief option.
This guide explains how worldwide income taxation, double taxation relief, and marital income attribution rules apply — with particular focus on residents who earn income on the French side (Saint-Martin).
Worldwide Income Tax in Sint Maarten
Under Art. 1 & 3 LvIB (the National Income Tax Ordinance — Landsverordening Inkomstenbelasting), the rule is clear and without exception:
- All residents of Sint Maarten are taxed on their worldwide income
- This applies regardless of where the income is physically earned
- There is no exemption for income earned on the French side of the island
If one spouse earns a salary in Saint-Martin (French side), that income must be declared on the Sint Maarten tax return. The physical location of the employer or the payroll system is irrelevant — what matters is the tax residency of the individual receiving the income.
Non-Compliance Risks: Why You Must Never Omit Foreign Income
Some residents mistakenly believe they can exclude foreign-source income from their Sint Maarten return to reduce their tax exposure. This is both incorrect and illegal.
Under the Algemene Landsverordening Landsbelastingen (ALL — the General National Tax Ordinance), the consequences of deliberate misreporting are severe:
Deliberately omitting or misreporting income can result in significant financial penalties and, in serious cases, criminal prosecution. The Sint Maarten Tax Authority has the authority to impose administrative fines, issue assessments with interest, and refer cases for criminal investigation.
Best practice: always report full and accurate income figures — even when the income was already taxed in another jurisdiction. The double taxation relief mechanism exists precisely to address this situation.
The Correct Filing Approach
To stay compliant and protect yourself from exposure, CaribTax recommends the following structured approach for residents with cross-border income:
File a Joint Tax Return (Form A)
Married couples in Sint Maarten are required to file jointly, combining both spouses' income in a single aangifte (Form A). This is not optional — it is a legal requirement under the LvIB.
Report All Worldwide Income
The return must include all income sources without exception: salary and business income from the French side, pension distributions, investment income, rental income, and any other foreign-source income received during the tax year.
Claim Double Taxation Relief
Sint Maarten provides an internal tax credit mechanism to reduce double taxation exposure. On the return, specify the country (Saint-Martin / France), the amount of income earned there, and the taxes already paid abroad. Attach supporting documentation including French tax assessments and payment receipts.
No Tax Treaty Between Sint Maarten and France
A critical point that many residents overlook: Sint Maarten does not have a tax treaty with France or Saint-Martin.
Existing Agreements
- Norway (tax treaty in force)
- Netherlands (certain arrangements)
- Former Netherlands Antilles (transitional framework)
No Agreement With
- France / Saint-Martin
- United States
- Most other countries
Because no treaty exists with France, any double taxation relief for French-side income is not treaty-based. Instead, it depends entirely on internal Tax Authority policy — a policy that is not formally published and is primarily referenced through jurisprudence (see: ECLI:NL:OGEAM:2018:97).
You may not always be able to eliminate double taxation entirely — but you are still legally required to declare all income and formally request the applicable tax credit on your return. Failure to declare is a compliance violation; the existence of potential double taxation does not create an exemption from reporting.
How Income Is Allocated Between Spouses
When filing jointly, Sint Maarten applies specific income attribution rules under Art. 20 LvIB. Understanding these rules is important for households where spouses earn in different jurisdictions or hold shared assets.
Personal Income
- Employment income
- Business and professional income
- Director's fees
Taxed to the spouse who earns it — regardless of where it originates.
Non-Personal Income
- Investment income
- Savings and deposit interest
- Shared assets
Allocated to the spouse with the higher personal income.
This distinction matters most when one spouse earns cross-border income while the couple holds shared investments or savings — the attribution rules directly affect how much each spouse owes and how double taxation relief is applied.
Why This Matters for French-Side Workers
Sint Maarten is a split island. The Dutch side (Sint Maarten) and the French side (Saint-Martin / Collectivité de Saint-Martin) share a land border with no passport control. Many residents live on the Dutch side and work on the French side — or vice versa.
From a Dutch Sint Maarten tax perspective, the side of the island where you work is irrelevant to your reporting obligations. The Belastingdienst Sint Maarten taxes you on all income, wherever earned. French authorities may also assert their own claim to taxation of income earned on their territory. This is precisely the situation the double taxation relief mechanism is designed to address — even without a formal treaty.
CaribTax has extensive experience handling cross-border income situations and will ensure your return is structured to claim every available credit while remaining fully compliant with Sint Maarten law.
