French vs Dutch Sint Maarten: Understanding Tax Implications of Each Side

Sint Maarten is a unique place in the world: a single 87-square-kilometer island shared by two sovereign nations. The southern Dutch side — Sint Maarten — is an autonomous country within the Kingdom of the Netherlands. The northern French side — Saint Martin — is a Collectivité d'Outre-Mer (overseas collectivity) of the French Republic, and technically part of the European Union.

This distinction has profound tax implications. For anyone considering relocation for tax optimization, it is essential to understand that only the Dutch side of the island has the Penshonado program. The French side operates under French tax law — which is emphatically not favorable for high earners.

The French Side (Saint Martin): EU Territory, French Tax Law

Saint Martin is an EU outermost region (région ultrapériphérique) and part of France. As a resident of Saint Martin, you are subject to French income tax — with marginal rates reaching 45% for income above €177,000, plus 17.2% social charges for high earners. The combined effective rate for a high-income individual can approach 60%.

Saint Martin does have some special provisions — it is not part of the EU's customs territory, and it has some local tax advantages on property transfers — but it has no equivalent to the Penshonado program. The French wealth tax (IFI — Impôt sur la Fortune Immobilière) also applies to French residents with real estate assets above €1.3 million.

EU VAT applies on the French side. Businesses selling goods or services to EU customers face the full French VAT regime. This is relevant for entrepreneurs running e-commerce or digital businesses from the island.

The Dutch Side (Sint Maarten): Kingdom of Netherlands, 10% Flat Rate

Sint Maarten is an autonomous country within the Kingdom of the Netherlands — not part of the EU. This means it operates outside EU VAT regulations, outside EU data protection directives (though it follows similar standards), and outside European capital requirements for financial services.

The absence of EU membership is a feature, not a bug, for most of our clients: it means Sint Maarten can set its own tax policy, its own financial regulation, and its own immigration rules — all within the stable framework of the Dutch Kingdom's rule of law.

The Penshonado program is exclusively available on the Dutch side. A qualifying resident of Sint Maarten pays 10% on worldwide income — period. There is no equivalent on the French side. This is the decisive factor for virtually all financially motivated relocators.

Practical Cross-Border Life

The border between the two sides is open — there are no passport controls, and many residents shop, dine, and socialize across the island freely. The French side (Grand Case, Marigot, Terres Basses on the French-Dutch border) is known for its restaurants, beaches, and charming village atmosphere. The Dutch side (Philipsburg, Simpson Bay, Maho) has the casino, airport, and commercial hub.

• You can live on the Dutch side and enjoy French-side beaches and restaurants without issue
• Property in Terres Basses (a premium beach area) is on the French side — not eligible for Penshonado purposes
• Your qualifying property for Penshonado must be on the Dutch side
• You can own vacation property on the French side separately — but it does not satisfy the Penshonado requirement
• For residency purposes, your principal residence must be documented as being on the Dutch side

Currency and Banking

The French side uses the Euro. The Dutch side uses the Netherlands Antillean Guilder (ANG), pegged to the USD at ANG 1.79 = USD 1.00. For most Penshonado clients with USD-denominated income, the Dutch side's effective USD economy is more convenient than the Euro-denominated French side.
