US Tax Rules When You Retire to Sint Maarten (2026 Guide)
You can move your body to Sint Maarten. You cannot move your tax obligation. The IRS taxes US citizens and green-card holders on worldwide income no matter where they live. And that’s the single most important sentence on this page. Everything else is structuring around that fact.
I’m a real estate agent, not a tax advisor. This piece walks through the framework I see my US-citizen retirees use successfully, so you can ask the right questions when you sit down with a CPA.
Key Takeaways
- US citizens continue filing US 1040s every year regardless of residence. Including from Sint Maarten.
- The Foreign Tax Credit (FTC) offsets US tax dollar-for-dollar by the SXM tax you pay (typically the 10% Penshonado rate on foreign income).
- State tax can persist if you don't cleanly break state residency. CA, NY, VA, NM, SC are aggressive.
- FBAR + FATCA reporting kicks in once you hold foreign accounts over the thresholds (FBAR: $10K aggregate; Form 8938: varying).
- The net effect: typically you cap global tax around your US federal bracket, avoid state tax on properly sourced foreign income, and gain a much lower SXM-side rate than what you'd pay in the US for the same income.
How the worldwide-income rule actually works
The US is one of two countries on Earth (Eritrea is the other) that taxes citizens on worldwide income, regardless of where they live. So when you retire to Sint Maarten:
- Your 401(k) distributions are still US-taxable.
- Your IRA distributions are still US-taxable.
- Your Social Security is still US-taxable (under the same rules).
- Your brokerage dividends and capital gains are still US-taxable.
- Rental income from properties anywhere. Including SXM real estate. Is reportable on the 1040.
The tools you have to manage double-taxation are the Foreign Tax Credit (FTC) and tax treaties.
There is no US–Sint Maarten tax treaty. SXM is part of the Kingdom of the Netherlands but not covered under the US-Netherlands treaty. The protection comes through the FTC, not a treaty.
The Foreign Tax Credit, in plain English
You file your US 1040 normally. You also file your Sint Maarten return (typically at ~10% Penshonado rate on qualifying foreign income). On the 1040, you take a Foreign Tax Credit (Form 1116) for the SXM tax you paid.
The math, simplified:
- Suppose you're in the 24% federal bracket on $150,000 of taxable retirement income.
- US federal tax (before credit): roughly $36,000.
- SXM Penshonado tax on the same income: roughly $15,000 (10% on qualifying foreign income).
- FTC: $15,000 reduces your US bill.
- Net US bill: $21,000.
- Total combined: $36,000. Same as if you stayed in the US federally.
So where does the savings come from? State tax. If you were in California, you’d add roughly 9-13% in state income tax on top of the federal. That’s $13,500–$19,500 you no longer owe (assuming a clean residency break from California). Same applies to New York, New Jersey, Massachusetts, Oregon, etc.
A retiree moving from California or New York routinely saves $15,000–$30,000 a year in tax just by clean-breaking state residency and structuring the SXM side right.
Breaking state residency cleanly
This is where retirees lose the savings they thought they had. State tax authorities don’t care that you spend 8 months a year in Cole Bay. They care about the legal indicia of residency.
A clean break typically requires:
- Sell or stop using your primary state residence as your home.
- Move your driver’s license to Sint Maarten or to a “residency-friendly” state (FL, TX, NV, WY, SD if you maintain a US address).
- Move voter registration. This is one of the most-cited indicia in audits.
- Update bank, brokerage, and IRA addresses.
- Update your primary care doctor and dentist.
- Notify your old state DOR with a final part-year return.
- Track your days. Keep a calendar showing days in/out.
The aggressive states audit. California and New York are the two most-cited. New Mexico, Virginia, and South Carolina each have their own quirks. If you’re leaving one of these, brief a state-residency CPA before you move.
Many retirees use a “stop-over state”. Formally establish FL, TX, or NV residency for 12 months before moving abroad. To neutralize the old state’s claim.
FBAR and FATCA: the two reports you cannot miss
Once you have a Sint Maarten bank account (and you will, for everyday life and for the Penshonado property purchase), you have foreign-account reporting obligations.
FBAR (FinCEN Form 114)
- Trigger: any combination of foreign financial accounts whose aggregate highest balance during the year exceeds $10,000.
- Includes: checking, savings, brokerage, certain insurance products, jointly held accounts
- Filed: electronically with FinCEN, not with the IRS, by April 15 (auto-extended to October 15).
- Penalty for non-filing: can exceed $10,000 per account per year; willful violations are far worse.
FATCA (IRS Form 8938)
- Trigger: higher thresholds than FBAR. Typically $200,000 year-end / $300,000 peak for a single filer living abroad; doubled for married filing jointly.
- Includes: broader scope than FBAR (some financial assets count for 8938 but not FBAR).
- Filed: with your 1040.
Good news: US Social Security is paid normally to retirees in Sint Maarten. You file Form SSA-7162 every other year to confirm you’re alive (literally), and the deposits continue.
Mechanics:
- Direct deposit to a US bank works fine. You then transfer to SXM as needed.
- Direct deposit to a SXM bank works in some cases via international wire setup. Ask SSA's international division.
- Withholding: there's no SSA withholding on benefits paid to US citizens abroad. You settle up at year-end on your 1040.
Estate and inheritance
The often-missed piece. As a US citizen, you remain subject to US estate tax on worldwide assets (current 2026 lifetime exemption is in the $13M+ range. Most retirees won’t hit it, but it scales down to $5M after 2026 sunset rules. Verify with your estate attorney).
Sint Maarten side: SXM has its own inheritance regime. Property held in SXM passes through SXM probate. Plan this with both a US estate attorney and a SXM notary; the right structure can save your heirs serious time and money.
What I see go wrong
The patterns:
- The “I’ll just keep my California address” client. California sends a letter 18 months in. The savings disappear.
- The “I forgot about FBAR” client. Five-figure penalty letter from FinCEN.
- The “I bought through my US LLC” client. SXM doesn’t necessarily honor the structure for Penshonado purposes; double-check before closing.
- The “I retired and didn’t file my 1040” client. US filing is forever, regardless of where you live. Even if your worldwide tax is fully offset by FTC, you must file.
Common questions
If I’m a green-card holder, do these rules apply to me? Yes. US permanent residents are treated the same as citizens for worldwide income. Some choose to expatriate (give up the green card) to escape this. That’s its own complex decision with the expatriation tax.
Can I avoid US tax by giving up citizenship? Technically yes via expatriation, but you may trigger the Exit Tax if you have $2M+ net worth or average tax liability over the threshold. This is a major decision; it’s not just a tax move.
Does the FEIE help retirees? No. The Foreign Earned Income Exclusion only applies to earned income (wages, self-employment). Pension, IRA, 401(k), Social Security are unearned. The FTC is the relevant tool.
What happens to my IRA RMDs in Sint Maarten? Required Minimum Distributions are still required at the same age and amount. They’re US-taxable, eligible for FTC offset against the SXM tax you pay on the same income.
Should I roll my 401(k) before moving? Often yes. IRAs give you more flexibility on distributions and custodians than employer-sponsored 401(k)s. Coordinate with a CPA.
Can I deduct property tax on my SXM home? There’s no traditional property tax in Sint Maarten the way US states have it. There are property-related fees and taxes (transfer tax, ground rent on long leases, condo HOA), but the standard SALT mortgage-interest-deduction stack from US residence doesn’t apply the same way.
What to do next
01
Read the Penshonado Program page if you haven’t. It sets the SXM-side baseline.
02
Hire a CPA with international experience before you move. Don’t try to retrofit.
03
Confirm your state residency exit plan and timeline.
04
Set up your FBAR/FATCA tracking from day one.
