St Maarten Capital Gains Tax: The U.S. Tax Reality (2026)
St Maarten capital gains tax is the question I get most from US owners, and the honest answer has two halves. On the Dutch side, the one holding-cost fact I can state plainly is that there is no annual property tax. How a sale itself is taxed locally is a question for a Sint Maarten tax advisor, not for me. And if you are American, the bill you plan for is usually the one waiting back home.
- Dutch side Sint Maarten has no annual property tax. That is the holding-cost fact I can state without hedging.
- How a sale is treated for local tax is a Sint Maarten tax-advisor question. Do not assume zero, and do not assume a bill.
- US citizens and green card holders are generally still taxed by the US on income earned abroad, which can include a gain on a Sint Maarten sale. Confirm your position with a US tax advisor.
- Buyer closing costs on the Dutch side run about 4 to 6 percent of price, roughly 4 percent transfer tax plus about 1 to 1.5 percent notary fee. Keep every document, because your tax advisor will want it.
Is there a capital gains tax in St Maarten?
On the Dutch side of St Maarten there is no annual property tax, which is the one holding-cost fact I can state plainly. For buyers coming from the US, where a yearly assessment from the county is simply part of owning a home, that removes a line item they have budgeted around their whole adult lives. How a sale itself is treated for local tax is a separate question, and it is not one I am qualified to answer. Ask a Sint Maarten tax advisor what applies to your specific sale before you count on any outcome in either direction.
The St Maarten capital gains tax question usually lands in my inbox before a buyer has even seen a property, and I understand why. The tax picture decides whether the whole plan works, so nobody wants to fall in love with a view first. Here is what I can tell you with confidence, because it is transaction mechanics rather than tax law. A civil-law notary is mandatory on the Dutch side and handles the title search, the deed, the escrow, and the registration, which is why buyers here do not use US-style title insurance the way they would at home. Your buyer closing costs when buying property in St Maarten run about 4 to 6 percent of the price, roughly 4 percent transfer tax plus about 1 to 1.5 percent in notary fees, and the seller usually pays the agent commission. There is no restriction on foreign ownership, so you can hold freehold title in your own name.
Keep every one of those purchase costs on file. Closing statements and improvement receipts are the first thing a tax advisor will ask for when they work out what your taxable gain actually is, and the owners who lose that paperwork are the ones who regret it years later, usually on a deadline. Scan whatever the notary hands you at closing, then start a folder for major work on the property from the day you get the keys. And a caution I give everyone: no annual property tax does not mean no holding costs. Utilities, insurance in a hurricane-belt market, and any association fees are all real, and I would rather you budget for them honestly than be surprised in your first year.
Do US citizens pay capital gains tax on Sint Maarten property?
In my experience US buyers are surprised by this one, so I flag it early: US citizens and green card holders are generally still taxed by the US on income earned abroad, and that can include a gain on a Sint Maarten sale. I am not a tax professional, so confirm how it applies to you with a US tax advisor who has actually handled foreign real estate, not just domestic returns. There is a real difference between the two, and you will feel it.
Where the house sits does not, on its own, take you out of the US system. Whether any local tax on your sale exists, and whether it could offset anything on the US side, is exactly the kind of question I send people to a tax advisor for. Do not assume either way until a professional has looked at your numbers. My guide on US tax rules for retirees in St Maarten covers more of the same ground, and the recurring theme in it is the same as here: the island is the straightforward part, and the paperwork that follows the money home is where people get tripped up.
The practical move is to bring the advisor in early rather than at the closing table. Before you buy, ask how the way you take title could matter, ask what records they want you to keep from day one, and ask what they would want to see if you sold in a few years. Those three questions cost you one phone call and they shape everything after.
I am an agent, not your accountant, and I will never pretend otherwise. What I can promise is that I have walked enough US buyers through this island to know where the trouble starts. It is almost never the local side. Line up a US tax advisor before you sell, not after you have accepted an offer, because by then your options have already narrowed.
How much St Maarten capital gains tax will a US seller actually pay?
I cannot give you a number, and I am not going to guess at one. Any agent who quotes you a percentage off the top of their head is telling you what they think you want to hear. What I can do is show you what the number gets built from, so you walk into your advisor’s office knowing which questions matter and which documents to bring.
Your gain is the sale price measured against what the property actually cost you, and what counts toward that cost is a determination your advisor makes, not something you or I decide from a blog. That is precisely why the paperwork matters so much: the record you kept is the raw material they work from. Here are the items I tell every US client to put on the list before they sit down with their accountant.
- Holding period: how long you hold the property can change how a US gain is treated. Your tax advisor can tell you what holding period matters in your case and whether it is worth timing a sale around it.
- Main-home relief: if the property was genuinely your main home rather than a vacation place, ask your tax advisor whether any US home-sale relief is available to you. I have seen people assume it applies when it does not.
- Rental history: if you rented the place out, how that past rental treatment affects the sale is a real question and one I cannot answer. Put it on the list.
- Currency: the US dollar is what you use day to day on the Dutch side, which keeps most of the transaction feeling familiar to a US buyer, though the official currency is the Antillean guilder. Ask your notary and your advisor which figures are recorded in which currency for your deal.
None of that is evasive. It is the difference between an agent who sells you certainty he does not have and one who tells you exactly where the certainty actually lives. My job is to get you the right price and the right buyer. Your advisor’s job is the return, and I would rather hand you a clean list of questions for them than a wrong answer of my own.
St Maarten vs Saint-Martin: how the tax side compares
One island, two nations, and no border checkpoint between them, which means people cross without thinking about it and then assume the rules travel with them. They do not. The Dutch side is generally lighter to buy and to hold. Saint-Martin, the French north, tends to cost more up front, often 7 to 8 percent in transaction costs, plus annual taxes that the Dutch side does not have. How France treats a sale is a separate question for a French tax advisor, and it is worth asking before you buy on that side rather than after.
Here is the side-by-side I show clients who are weighing both coasts. Notice that the honest rows are the ones that send you to a professional, and that is the point. For a fuller breakdown of daily life, currency, and the practical differences, see my comparison of St Maarten vs Saint-Martin.
| Factor | Dutch side (Sint Maarten) | French side (Saint-Martin) |
|---|---|---|
| Land area | About 34 sq km | About 53 sq km |
| Buyer closing costs | About 4 to 6 percent | Often 7 to 8 percent |
| Annual property tax | None | Yes, annual taxes apply |
| Tax treatment of a sale | Confirm with a Sint Maarten tax advisor | Confirm with a French tax advisor |
| Everyday currency | US dollar | Euro |
| Foreign ownership | No restriction, freehold | French and EU rules |
The two sides sit on 87 sq km of shared ground, and a ten minute change of scenery can mean a different currency, a different notary system, and a different set of professionals to call. That is not a reason to avoid the French side. It is a reason to decide which side your title sits on with your eyes open, and I walk clients across both when they are still deciding.
What US filings should you plan for when you sell?
Plan for reporting, not only for a tax payment. If your sale proceeds sit in a local account, there may be US reporting obligations attached to holding money offshore. I am not going to name forms or thresholds, because that is your accountant’s territory and getting it slightly wrong in public helps nobody. Raise it with your tax advisor before the money moves, not after it has been sitting somewhere for a year.
Two other things worth flagging while you are making that list. First, do not assume you can defer a US tax bill by rolling a Sint Maarten property into a US one. Deferral mechanics are a tax-advisor question, and the answer can decide whether a sale even makes sense, so ask before you list. Second, Canadian owners face an entirely different regime, which I cover in my note on Canadian tax treatment for St Maarten owners. If you hold both passports, that conversation gets more involved, not less.
What I can help with is the timeline. A sale here moves at the pace of the notary, the buyer’s financing, and the season, and the tax conversation should start well before any of that. When I take a listing I ask sellers to have their advisor briefed in advance, because a question that takes three days to answer in July can cost you a buyer in a market this small.
On the Dutch side the surprise is rarely the island. It is the paperwork that follows the money home.Wei Landgraf, Dutch-side resident agent
What can you actually control when you sell your SXM home?
You cannot rewrite tax law, and neither can I. What you can control is your preparation, your paperwork, and your timing, and in my experience those three things move the final net number more than anything else a seller does. Owners who plan lose less to avoidable mistakes than owners who react to an offer.
- Save every closing statement, invoice, and improvement receipt from the day you buy. Your tax advisor will ask, and a complete file is worth more than a good memory.
- Ask your tax advisor early how the holding period, any main-home relief, and any past rental use interact in your specific situation, so nothing surprises you at the last minute.
- Ask a Sint Maarten tax advisor what, if anything, the local side means for your sale. Get a real answer rather than a rough one from an agent.
- Coordinate the closing date with your advisor, since the calendar can change when a bill comes due and that is a conversation to have before you sign, not after.
- Price and position the property properly. That part is mine, and it is the lever that actually moves the number at the top of the page.
When you are ready to line up a sale, I can handle the market side while your advisor handles the return, and the two of us should be talking to each other rather than to you in turn. Start with my overview of St Maarten real estate to see where your property sits, then send me the address and I will give you a realistic read on what it will do in today’s market.
Frequently Asked Questions
Does Sint Maarten have a capital gains tax on real estate?
The fact I can confirm is that the Dutch side has no annual property tax. How a sale itself is treated locally is a tax question rather than a real estate question, and I am not the person to answer it. Ask a Sint Maarten tax advisor about your specific sale before you assume anything in either direction.
Do I pay US capital gains tax if I sell my house in St Maarten?
If you are a US citizen or green card holder, the US generally still taxes income you earn abroad, and that can include a gain on a St Maarten sale. Whether the local side changes anything for you is a separate question. Confirm the US side with a tax advisor who has handled foreign real estate, and the local side with a Sint Maarten tax advisor.
Does how long I own SXM property change the US tax on my gain?
It can. Holding period is one of the things that can change how a US gain is treated, and your tax advisor can tell you what holding period matters in your case and whether it is worth timing a sale around. Get that from a professional rather than from a rule of thumb off a blog.
Is there an annual property tax in St Maarten?
Not on the Dutch side. Sint Maarten does not charge an annual property tax, which is one reason holding costs stay lower than on the French side, where annual taxes do apply. Utilities, insurance, and any association fees are still real recurring costs, so budget for those.
Is there any US relief if the St Maarten home was my main residence?
Possibly, and it is worth asking. If the property was genuinely your main home rather than a vacation place or a rental, ask your tax advisor whether any US home-sale relief is available to you. I have seen people assume it applies when it does not, and that is an expensive assumption to discover late.
Can I roll a St Maarten sale into a US property to defer the tax?
Do not assume you can. Deferral mechanics are a tax-advisor question, and the answer can decide whether a sale makes sense at all, so ask before you list rather than after you have accepted an offer.
