Taxation in Saint Barthélemy for Expats: Income Tax and Property Tax

Published on May 5, 2026 and written by Cyril Jarnias

Moving to Saint Barthélemy is a dream for many expatriates, not only for its beaches. The island has a unique tax regime within France, with extensive autonomy and rules that have nothing to do with mainland France. Between the absence of income tax for some, specific taxation of real estate capital gains, and the reality of local property tax, the picture is attractive but far from simple.

Good to know:

This article details the main taxes concerning expatriate property owners in France: income tax and property tax. It also covers related consequences such as determining tax residency, the regime for real estate capital gains, and inheritance taxes.

Understanding the Specific Tax Status of Saint Barthélemy

Saint Barthélemy is an Overseas Collectivity governed by Article 74 of the Constitution. Since 2007, it has had its own fiscal sovereignty, organized in a local Tax Code. Concretely, French tax law does not apply automatically: the collectivity votes on its own taxes, provided it respects the broad principles of French legislation.

Caution:

The island enjoys broad fiscal autonomy: no VAT, no local income tax for long-term residents, and no wealth tax (ISF/IFI) on local real estate. However, certain national contributions, such as CSG and CRDS on some income, still apply.

For an expatriate, this creates a hybrid landscape: on one hand, a very light local environment for direct taxation, and on the other, the persistence of French tax as soon as a connection with mainland France is maintained (real estate, French-source income, etc.).

Tax Residency: The Five-Year Threshold

It all starts with a key concept: tax domicile. In Saint Barthélemy, the criteria are based on Article 4 B of the French General Tax Code, but with an additional length-of-stay requirement.

Criteria to Be a Tax Resident of Saint Barthélemy

An individual is considered to have his or her tax domicile in Saint Barthélemy if, as of January 1 of the tax year, he or she meets at least one of the following conditions for at least five consecutive years:

– their home or main place of stay is located in Saint Barthélemy;

– they exercise their main professional activity, whether salaried or self-employed, there;

– the center of their economic, material, and moral interests is located on the island.

Good to know:

As long as the five-year residency period has not been reached, the person is considered a ‘new resident.’ Legally, if they were previously a resident of mainland France, they are in principle tax domiciled in France during this period.

The same type of logic applies to companies: to be a resident of Saint Barthélemy, a legal entity must have its effective place of management on the island for at least five years, or be effectively managed from the island and controlled by persons who are themselves local tax residents.

Residents, New Residents, Non-Residents: Three Tax Situations

To fully understand the impact on income tax and property taxation, it is useful to distinguish three profiles of expatriates.

This distinction may seem technical, but it determines everything: presence or absence of local income tax, exposure to French tax, risk of double taxation, treatment of real estate capital gains, inheritance taxes, etc.

Income Tax: A Paradise… for Established Residents

This is the flagship argument often put forward: an individual who has had their tax domicile in Saint Barthélemy for more than five years pays no local income tax, nor wealth tax on assets located on the island. In practice, for their exclusively local-source income, there is no progressive tax scale as in France.

But this advantageous picture has three major limitations that expatriates should factor in from the start.

1. No Local Income Tax, But No Global “Zero Tax”

A tax resident of Saint Barthélemy pays no income tax on their local-source income (activities carried out on the island, rents from buildings located there, etc.), nor ISF/IFI on their local assets. However:

Tip:

For tax residents of Saint Barthélemy, French-source income remains taxable in France, but under the specific regime for non-residents. Additionally, in some cases, social contributions (CSG/CRDS) remain due on some of this income. Finally, income from other countries remains subject to the tax laws of those states, without automatically benefiting from the French tax treaty network, since tax residency is established in Saint Barthélemy, not in ‘fiscal France.’

A local tax resident who keeps an apartment rented out in Paris, a portfolio of French securities, or a retirement pension paid by a French fund may therefore be very lightly taxed on their St. Barth income, but remain heavily taxed on their French-source income.

2. The Fate of New Residents: A Tricky Five-Year Transition

An expatriate who comes to settle on the island immediately becomes, under local law, a resident of Saint Barthélemy, but remains fiscally considered a resident of France until they have crossed the five-year residency threshold. This is the so-called “new resident” phase.

During this period:

Good to know:

Income from all sources remains taxable in France for income tax purposes. However, some income or capital gains from Saint Barthélemy sources may also be subject to local taxation, creating a risk of double taxation. To limit this accumulation, a tax credit is provided: the tax paid to Saint Barthélemy is deducted from the French tax due on the same base, up to the amount of the latter, without entitlement to a refund if the local tax is higher.

In other words: for five years, a new resident remains largely in the French tax fold, while beginning to enter that of Saint Barthélemy for some local income. Only at the end of this period do they fully switch to the local income tax exemption regime.

3. Non-Residents: Targeted Local Taxation Plus Taxation in Country of Residence

An expatriate who does not live on the island (for example, an American or Italian owner of a vacation villa in Saint Barthélemy) remains taxed in their country of residence on their worldwide income, but may be subject to several local taxes:

– tax on real estate capital gains when reselling a property located on the island;

– annual tax of 3% on the market value of properties held through legal structures (companies, trusts, etc.), unless exceptions apply;

– possibly gift and inheritance taxes on assets located on the island according to specific rules.

On the other hand, they are not subject to a generalized local income tax, and the taxation of their possible rental income will in practice be that of their state of residence, except in specific cases.

Property Tax in Saint Barthélemy: What Expatriate Owners Really Have to Pay

Amid this sophisticated system, property tax plays a much more classic role: funding local services and public facilities. However, it remains very specific in three respects: the cadastral base, the rates voted, and its articulation with the rest of real estate taxation.

Who Pays Property Tax and on What Basis?

As in mainland France, property tax is owed by the owner (or usufructuary, or fiduciary) who holds the property on January 1 of the tax year, whether the home is occupied by them, rented out, or vacant. The tenant is not liable. In case of a sale during the year, the seller remains in principle legally liable for the full year, unless a proration clause is provided in the deed.

The calculation basis is the “cadastral rental value”, i.e., the theoretical annual rent that the property could generate if rented under normal conditions. This value:

Example:

The cadastral rental value, which serves as the basis for calculating the housing tax and property tax, incorporates several criteria such as surface area, geographic location, level of comfort, environment, and state of maintenance of the property. However, it is calculated using reference grids drawn up in 1970 for developed properties and in 1961 for undeveloped ones, which have never been thoroughly revised since. Although this value is increased by a flat-rate adjustment each year, it is based on these old benchmarks, often very far from actual market prices. This gap is particularly marked in territories like Saint Barthélemy, where real estate values have increased considerably.

To obtain the taxable base, a deduction is applied:

– 50% of the rental value for developed properties, supposedly covering charges, insurance, maintenance, repairs;

– 20% for undeveloped properties.

The resulting amount, called the net cadastral income, is then multiplied by the rates voted by the collectivity.

Rate Levels: Currently Almost No Tax Burden

Local decisions have a decisive impact here. Elected officials cannot control cadastral values, only the rates. However, known data shows an extremely moderate policy in Saint Barthélemy in recent years.

The figures for 2013 and 2014 indicate a rate of 0% for both developed and undeveloped properties. In other words, for those years, the municipal property tax based on the cadastral value was zero. Historically, we even observe that between 2000 and 2014, rates increased more in Saint Barthélemy than in comparable French municipalities, but from a very low level and, at certain dates, remained set at 0%.

We must therefore distinguish two things:

– legally, property tax exists, with its rules for base, deductions, calculation, and the collectivity’s ability to set rates;

– practically, rates may have been set at zero in some years, which effectively neutralizes property tax for those periods.

Caution:

For an expatriate property owner, property tax can currently be very low or even zero. However, this situation is not guaranteed over time, as rates are reviewed annually by the local authority, which could increase them in the future to finance new services or investments.

Developed Properties, Undeveloped Properties, and Possible Exemptions

Property tax applies to two main categories of property:

– developed properties: houses, apartments, parking spaces, commercial premises, fixtures attached to the ground…;

– undeveloped properties: vacant land, gardens, agricultural land, quarries, bodies of water, etc.

An interesting feature for real estate investors is the possible existence of temporary exemptions for certain new constructions, extensions, or reconstructions, for periods ranging from 2 to 30 years, depending on the measures voted. They can make property tax almost negligible for a new project, especially in the high-end segment.

For expatriates, the issue is not only the amount of current property tax, but its potential trajectory. On an island where land is scarce and the theoretical rental value high, a future increase in rates could cause the bill to skyrocket, despite historically outdated cadastral bases.

Real Estate Capital Gains: The Real Heavy Taxation of the Island

For expatriate property owners, especially those considering buying a second home or a rental property, the most significant tax is not income tax, often zero locally, but the tax on real estate capital gains.

High Rates, Adjusted by Holding Period

Any developed or undeveloped property located in Saint Barthélemy, as well as certain real estate rights or shares in companies with a predominant local real estate component, is subject to a specific tax when sold at a gain. This tax concerns:

– individuals, whether residents, new residents, or non-residents;

– legal entities, local or foreign, provided the property is located on the territory of the collectivity.

The scale is simple in appearance:

However, this rate does not apply to the entire gross gain over time. A reduction mechanism

– of 10% per year from the 9th year for secondary residences,

– of 20% per year from the 9th year for a primary residence,

gradually eliminates the taxable base.

Concretely, for a secondary residence purchased for value, the gain becomes fully exempt after 18 years of ownership. For a primary residence meeting the conditions, full exemption can be achieved after 13 years.

Added to this are specific rules for properties received free of charge (gift, inheritance) where the reduction can be 20% per year after the 8th year, also leading to full exemption after 13 years.

Calculating the Gain: Sale Price, Acquisition Price, and Adjustments

The calculation of the gross gain starts from the difference between the transfer price and the acquisition price, but several elements serve to increase the purchase base or decrease the sale price:

– the acquisition price can be increased by acquisition costs (notary, registration fees) and certain works, subject to supporting documents;

– the sale price can be reduced by commissions paid to an intermediary (agency, agent), again subject to proof.

Good to know:

After determining the gross gain and applying the holding period reduction, the applicable tax rate is 35% or 20% depending on your situation. Non-residents or residents of a third state may have additional obligations, such as appointing a tax representative on the island.

It is important to note that, unlike mainland France, this local capital gains tax does not include local CSG/CRDS for the primary residence. However, for secondary residences, social contributions may be added in some cases.

Possible Double Taxation for French Residents or New Residents

For expatriates of French origin, the crucial question is the potential overlap of this local tax with the French tax on real estate capital gains.

Good to know:

For a French tax resident realizing a capital gain on a property in Saint Barthélemy, taxation occurs both in France (standard real estate capital gains rate) and in Saint Barthélemy (20% or 35% tax). A tax credit in France, corresponding to the amount paid in Saint Barthélemy (up to the amount of French tax due), prevents full double taxation.

But if the local tax exceeds the theoretical French tax, the difference is definitively borne by the taxpayer, without refund. This is typically the case for significant short-term gains, where the local 35% rate can far exceed the French duo of 19% plus deductions.

For an “established” tax resident of Saint Barthélemy, considered a non-resident by France, the situation is different: France does not tax the gain on a property located in Saint Barthélemy, only on properties in mainland France or overseas departments. The tax therefore remains entirely local for island properties, but the person remains exposed to the French non-resident regime for any properties they may have in France.

3% Tax on Market Value and Other Real Estate Levies

Beyond property tax and capital gains, another important real estate tax for expatriates is the annual 3% tax on the market value of properties held through entities.

The Annual 3% Tax on Properties

This tax applies to:

– companies, trusts, or organizations, regardless of their form or registered office, that directly or indirectly hold properties located in Saint Barthélemy or real rights over such properties.

The principle is simple: each year, 3% of the estimated market value of the held properties must be paid, unless exceptions apply.

Two main exemption avenues exist:

Good to know:

Entities whose registered office is in mainland France are exempt from this tax. Other entities can also avoid it by filing, each year before March 31, a declaration detailing the ownership structure and the value of the properties concerned.

For an expatriate who structures their investments via an offshore company or a foreign trust, this measure can represent a significant long-term cost if not properly managed. For those using a French company, the exemption from this tax is a factor to consider when choosing the investment structure.

Other Levies Related to Ownership

The local tax arsenal also includes:

30

This is the percentage rate of the quay duty applied to heavy goods vehicles over 14 tonnes, increasing construction costs.

For an expatriate investor in tourist rentals, these indirect levies sometimes weigh more, in the long run, than property tax alone.

Income Tax, Rents, and Social Contributions: Pitfalls to Avoid

On rental income from properties located in Saint Barthélemy, the situation varies greatly depending on the owner’s status.

For a local tax resident “established” for five years, rental income from a property on the island is not subject to local income tax. However, this rental income may still be subject to CSG/CRDS at an overall rate of around 15.5% to 17.2% on net income, depending on the texts. This means an owner may pay no income tax, yet still owe significant social contributions.

Good to know:

For a French property owner residing in mainland France or a new resident, rental income from a property in Saint Barthélemy is taxable in France for income tax purposes (micro-foncier or actual regime) and subject to social contributions (CSG/CRDS). The collectivity of Saint Barthélemy generally does not levy income tax on these rents. However, if the property is rented short-term to tourists, the tourist tax applies.

Finally, for a non-resident (for example a Swiss or American), rental income is logically taxed according to the tax law of their country of residence, as the collectivity does not currently impose a specific tax on non-resident rental income, apart from the measures discussed (3% tax on market value, tourist tax, capital gains on resale).

Inheritance, Gifts, and Wealth: A Very Favorable but Complex Framework

For high-net-worth expatriates, a major point often glossed over in “tax haven” presentations is the treatment of transfers (inheritance and gifts) in Saint Barthélemy.

Tax residents of more than five years benefit from an extremely advantageous regime for assets located on the island:

150000

The tax allowance for gifts to children or parents is €150,000, with a tax rate that can be reduced to 0% under certain conditions.

However, the devil is in the details:

Caution:

If the deceased did not have Saint Barthélemy as their last domicile, or if their heirs are not sufficiently domiciled there, France may tax the inheritance according to its own rules. For expatriates from countries with their own inheritance tax, the combination of local, French, and foreign rules is highly technical, especially in the absence of a specific tax treaty between Saint Barthélemy and the foreign state concerned.

Regarding the real estate wealth tax (IFI), the situation is simpler: tax residents of Saint Barthélemy are not subject to it for their assets located on the island, but remain taxable in France on their French real estate assets above a certain threshold (net value exceeding €790,000 mentioned in some texts, €1.3 million in current French law).

Practical Summary for an Expatriate Property Owner in Saint Barthélemy

By cross-referencing all the rules, we can identify some useful guidelines for an expatriate interested in income tax and property tax on the island.

For a tax resident of more than five years:

Tip:

Taxation in Saint Barthélemy has specific characteristics for non-residents: there is no local income tax on Saint Barthélemy-source income. Property tax exists but its rate can be very low or even zero, depending on the vote of the local authorities. Upon resale, real estate capital gains are heavily taxed (35% or 20%), but full exemption is possible after a long holding period (13 or 18 years) thanks to progressive reductions. Inheritance taxes on assets located on the island are non-existent, and gifts are very lightly taxed. However, note that CSG/CRDS may apply to certain income (such as rental income or French-source income), and French-source assets and income remain subject to standard French non-resident taxation.

For a new resident:

Good to know:

For French tax residents in Saint Barthélemy, French income tax applies to all worldwide income. The collectivity may levy local taxes on certain local-source income or capital gains. A French tax credit is applied to limit double taxation, but it does not fully compensate if the local tax rate is higher than the French rate. Property tax follows standard rules, applicable to any owner regardless of their tax residence.

For a non-resident:

– the main tax regime remains that of their country of residence;

– Saint Barthélemy intervenes mainly through property tax (if rates are voted), the tax on real estate capital gains, the annual 3% tax on the market value of properties held through entities, the tourist tax, and certain transfer duties;

– certain structures (a French company owning the property, filing requirements) can avoid the 3% tax, but not the taxation of capital gains or the filing obligations.

An Attractive Framework, But to Be Handled with Caution

At first glance, the combination of “no income tax / no IFI / very low local inheritance taxes / low property tax” makes Saint Barthélemy a paradise for wealthy expatriates. But reality is more nuanced.

Three elements should capture the attention of any candidate for tax expatriation:

1. The five-year condition: until this duration is met, French taxation largely persists, even as some local taxes are already being imposed. Moving to “escape tax” therefore only makes sense in the long term and with a genuine relocation.

Caution:

The absence of a general tax treaty with France and most states exposes one to high risks of double taxation and residency conflicts, especially for real estate capital gains and pensions. This situation also limits the scope of treaties that France has signed with other countries.

3. The persistence of French taxation on French-source income and assets: a tax resident of Saint Barthélemy remains a French non-resident, but they are still taxable in France on their French rental income, their French real estate capital gains, certain investment income and pensions, as well as IFI on their French real estate assets.

For an expatriate considering settling in Saint Barthélemy, or investing in real estate there, the tax strategy cannot be reduced to simply looking at the local income tax rate (zero) and the current property tax policy (very low). It requires:

Tip:

For international tax and estate planning optimization, it is crucial to carry out: a precise analysis of your tax residence status over the past five and next five years; a detailed mapping of your assets (geographic location and legal form of ownership); a projection of the holding period for local real estate to measure the impact of capital gains and reductions; and anticipation of family transfers (gifts, inheritances), in order to benefit from favorable local regimes while avoiding double taxation or tax reassessments.

In this context, guidance from a professional familiar with both the Saint Barthélemy Tax Code and French (and international) tax law is not a luxury, but a necessity, especially since the island, as an autonomous collectivity, continues to evolve its tax law through successive deliberations.

For expatriates, Saint Barthélemy offers a unique tax framework within the French space, particularly attractive for income tax, IFI, property tax, and transfers. But precisely because this regime is exceptional, it must be approached methodically, patiently, and with a good dose of caution.
