why - St Martin / Sint Maarten Island

1. Quick Reference: St Martin / Sint Maarten

  • ➜ One island, two nations — French COM (north) and Dutch constituent country (south), open border since 1648
  • ➜ Both sides: No income tax, no capital gains tax on real estate
  • ➜ French side (Saint-Martin): French legal framework, notaire process, Euro, COM fiscal autonomy similar to St Barts
  • ➜ Dutch side (Sint Maarten): Dutch civil law, ANG (guilder) legal currency, USD widely used, Dutch Caribbean fiscal framework
  • ➜ Princess Juliana International Airport (SXM): One of the Caribbean's busiest, direct connections to Amsterdam, New York, Miami and more
  • ➜ Gateway to St Barts: 10-minute Winair hop from SXM — the essential St Barts connection hub
  • ➜ No foreign ownership restrictions on either side — all nationalities may purchase freely
  • ➜ Orient Bay: the French side's internationally celebrated beach resort, villa and lifestyle hub
  • ➜ Terres Basses: the French side's ultra-premium villa estate peninsula — one of the Caribbean's finest private addresses
  • ➜ Hurricane Irma (2017): Category 5 devastated both sides — post-Irma rebuild status is the most critical due diligence item for any purchase
  • ➜ St Barts is 20 minutes away by fast ferry or 10 minutes by island-hop aircraft from Princess Juliana Airport

2. Pros & Cons: An Honest Assessment

The Advantages

  1. No income tax, no CGT on both sides: The complete absence of personal income tax and CGT on both the French (COM fiscal autonomy) and Dutch (Sint Maarten fiscal framework) sides creates one of the Caribbean's most complete and most flexible tax-neutral property holding environments — with the buyer's choice of which jurisdiction's legal and regulatory framework best serves their specific needs
  2. One island, two jurisdictions — genuine flexibility of choice: The ability to choose between the French legal system's robust notarial protections and EU framework on one hand, and the Dutch Caribbean's more commercially oriented framework on the other, within a single open-border island is unique in the Caribbean property market. Buyers can select the jurisdiction that best aligns with their nationality, residency plans, legal preferences, and lifestyle priorities
  3. Princess Juliana Airport — exceptional Caribbean connectivity: Direct KLM, American, United, Delta, and other services make SXM one of the most internationally connected airports in the Lesser Antilles — and the essential hub for St Barts access. The airport's connectivity is a fundamental demand driver for both sides' property and rental markets
  4. The St Barts gateway premium: Proximity to and connectivity with St Barts — the Caribbean's most exclusive market — elevates the entire island's visitor quality, rental rates, and commercial infrastructure in ways that are commercially real and durably valuable
  5. The most cosmopolitan market in the Caribbean:Over 70 nationalities in the permanent population, French and Dutch legal systems, a diverse buyer community from Europe, North America, and beyond — the island's cosmopolitan character creates a property market of unusual depth and international liquidity
  6. Grand Case — one of the Caribbean's finest restaurant concentrations: Five-year pathway to French (EU) citizenship for genuine long-term residents of the French side — the most complete and most internationally valuable citizenship outcome available through Caribbean residency
  7. The open border — lifestyle freedom across both sides: The Treaty of Concordia border, open since 1648, gives residents of both sides daily access to the whole island's lifestyle, beach, dining, and commercial infrastructure without any formality

    8. The Considerations

  8. Hurricane Irma (2017) — the most critical due diligence issue in this guide: Category 5 destruction of approximately 90% of the island's structures. Post-Irma construction quality, rebuild status, and insurance history are non-negotiable due diligence requirements for every property on the island. Do not purchase any property on either side without specific, documented confirmation of post-Irma rebuild status and construction quality
  9. Two separate legal systems — complexity for buyers who own on both sides: Buyers who wish to own on both sides of the island must navigate two separate legal systems, two separate purchase processes, two separate fiscal frameworks, and two separate professional relationships — with notaires and attorneys on each side. This is manageable but requires careful organisation and clear professional relationships
  10. British and non-EU buyers — 90/180-day Schengen limit on French side: British post-Brexit buyers who want to spend extended periods on the French side must arrange appropriate French long-stay immigration status — the tourist admission Schengen rule is a real constraint for buyers who wish to use the French side as a primary or extended residence
  11. US citizens — no relief from US worldwide taxation: The no-tax environment on both sides provides no relief from US federal income, CGT, or estate tax obligations for US citizens and US persons. Specialist US tax advice is mandatory
  12. No citizenship by investment programme: Neither Saint-Martin nor Sint Maarten has a CBI programme — for buyers whose primary objective is second citizenship, the other Eastern Caribbean islands (St Kitts, Grenada, Saint Lucia, Antigua, Dominica) are the relevant destinations
  13. Smaller market than some regional comparators — limited resale liquidity: The island's small size means that the premium property market has limited transaction volume and can have extended marketing periods for resale, particularly for properties at the higher price points
  14. Cruise ship day visitor congestion in Philipsburg: On major cruise ship days, Philipsburg and the surrounding area can be extremely congested — a consideration for buyers whose property or lifestyle is centred on the Dutch-side capital area
