Expatriation to Mauritius: taxation, company, residence and settling in.
Summary
Introduction
Expatriation to Mauritius is never simply a matter of a plane ticket and a residence permit. It rests on four interconnected pillars: Mauritian taxation, company structure, residency status, and physical relocation. Addressing one while neglecting the other three is the primary cause of the complex cases we see in our office.
The short answer can be summed up in one sentence: Mauritius offers a moderate, transparent, and tax-compliant framework with France, but the real benefit depends far more on the actual severance of your French ties than on the tax rate displayed in Port Louis. In other words, obtaining an Occupation Permit and a Mauritian residence certificate is not enough: if even one of the four criteria of Article 4 B of the French General Tax Code remains met in France, you remain a French tax resident and liable for tax on your worldwide income.
This article outlines the four steps in the order they should be addressed, explaining at each stage what falls under Mauritian law and what falls under French law. You will find the control points examined by the tax authorities, the documents to gather from the first year, and a suggested timeline. A well-managed transfer of tax residence to Mauritius requires preparation over several months, not just a few weeks.
The rates, thresholds, and deadlines mentioned here are general guidelines that change in line with Mauritian and French finance laws. They should be verified as of the date of your project and, above all, considered in light of your personal circumstances: household composition, type of income, securities holdings, and real estate assets. Only an individual assessment can determine the most suitable option for your specific situation.
Expatriation to Mauritius: the answer in brief
Mauritius is a good option for entrepreneurs or executives whose businesses can be relocated and who are willing to move their primary residence to the Indian Ocean. The country combines a standard corporate tax rate of 15%, a progressive personal income tax scale with a marginal rate significantly lower than the French scale, and no capital gains tax or inheritance tax. These figures are publicly available and can be verified with the Mauritius Revenue Authority.
However, the country is not a tax-free territory, and that is not in its interest. Its interest lies in being a treaty-bound, cooperative, and credible state : Mauritius applies the automatic exchange of information on financial accounts, was removed from the FATF grey list in October 2021, and has a tax treaty with France signed on December 11, 1980, and subsequently amended by protocols. This credibility is precisely what makes a case defensible before the French tax authorities (DGFiP).
The essential condition remains a clean exit from the French side. We detailed this process in our article on how to cease being a French tax resident from Mauritius , and this article focuses on the next level: how to properly coordinate taxation, company, residence, and relocation.
The four parts and their logical order
The common reflex is to create the company first, because it's the most visible step. This is often the least protective order, as a Mauritian entity owned and managed from France can be taxed in France through its effective management headquarters . The order that holds up in the face of an audit is generally: life decision and timeline, then residence permit, then physical establishment, then company structure, then transfer of client flows.
Each section produces supporting documents, and it is these documents that will serve as proof when the administration asks questions. An expatriation file is first and foremost a file of evidence compiled in real time of the events, never reconstructed three years later.
The tax aspect: what Mauritius actually imposes
The Mauritian tax system operates on a fiscal year running from July 1st to June 30th, which automatically shifts your tax obligations relative to the French calendar. Resident individuals are taxed according to a progressive tax scale, reformed in 2023, organized into brackets with a top marginal rate of around 20% . In addition, there are social security contributions specific to Mauritian law, including the local generalized social contribution.
Resident companies are subject to a standard 15% corporate income tax. Certain foreign-source income received by entities holding a Global Business Licence may be eligible for a partial exemption, which reduces the effective tax burden to a significantly lower level, subject to strict substance requirements verified by the Financial Services Commission.
Two absences are as important as the rates themselves. Mauritius has no capital gains tax on the sale of securities or real estate, no inheritance tax, and no wealth tax. For an executive planning a wealth management transaction, this structure changes the nature of their thinking , but it never eliminates the French exit tax if the departure occurs after the unrealized capital gain has been realized.
What remains taxable in France despite leaving
Becoming a non-resident does not eliminate the French tax base. Income from French sources remains taxable in France according to territoriality rules, with a minimum tax rate applying unless a lower average rate can be demonstrated. Rental income from property located in France remains taxable in France, and the withholding tax on dividends provided for in Article 119 bis of the French General Tax Code continues to apply to distributions from your French companies.
One point deserves particular attention, as it distinguishes Mauritius from other European destinations. The reduced solidarity levy on investment income is reserved for individuals affiliated with a social security scheme in the European Economic Area, the United Kingdom, or Switzerland. A Mauritian resident does not meet this condition and therefore pays the full social security contributions at the standard rate on their French rental income and capital gains. The same reasoning applies to a tax return filed by a French resident in Portugal compared to one in Mauritius, where the outcome differs precisely on this point.
The trap of "rate versus rate" reasoning
Comparing 20% Mauritian to 45% French makes no sense in isolation. The actual tax burden depends on the nature of your income, its source, the applicable tax-sharing rules, and the social security contributions levied on each side. A simulation based on your actual cash flow often reveals a very different discrepancy than initially anticipated.
The residence component: permits, days of presence and status
Mauritius, like the United Arab Emirates, carefully distinguishes between the right to reside and tax status. Residency permits are obtained from the Economic Development Board, primarily through the Occupation Permit, which is issued in three categories: investor, salaried professional, and self-employed worker. There is also a Premium Visa for long-term stays without local employment, and a residence permit for retired non-citizens.
Each option requires meeting conditions set by Mauritian law: initial transfer of funds for the investor, minimum turnover for the self-employed individual, and a minimum monthly remuneration for the professional. These thresholds are regularly updated by successive budgets and should be verified on the exact date of filing rather than taken from an online article.
The two attendance rules you need to know
Mauritian tax residency for individuals is determined by two alternative physical presence tests. The first requires a presence of at least 183 days during the tax year. The second, less well-known but often decisive for individuals with high mobility, requires a cumulative presence of at least 270 days over three consecutive tax years .
These counters are documented, not declared. Always keep boarding passes, passport stamps, local bank statements, and utility bills. A real-time attendance log is infinitely better than a belated reconstruction under pressure from an audit .
The tax residence certificate issued by the Mauritius Revenue Authority will then formalize your status. It certifies that Mauritius treats you as a resident according to its own rules, which is necessary to activate the tax treaty, but it says nothing about your remaining ties to France .
The company aspect: GBC, Authorised Company and substance
Two structures dominate the projects of French entrepreneurs. The Global Business Company, or GBC, is a Mauritian resident company, subject to local taxation and eligible for tax treaties signed by Mauritius. The Authorized Company, on the other hand, is treated as a non-resident company, must be managed and controlled from abroad, and does not have access to the Mauritian tax treaty network.
This choice is not merely cosmetic. If your objective is to be able to invoke the Franco-Mauritian convention against the French administration, the Authorized Company is structurally unsuitable, as it is not resident in the conventional sense. A serious business relocation to Mauritius therefore begins with this qualification, before any registration process.
Substance is not a mere formality of declaration.
The Financial Services Commission expects a Global Business Corporation (GBC) to have real and verifiable substance: a sufficient number of resident directors, effective holding of board meetings in Mauritius, a registered office and physical assets in the country, proportionate local expenditures, and a level of employment consistent with the declared activity . These requirements stem from the economic substance rules adopted in line with the BEPS work.
From the French perspective, the corresponding risk is that of a permanent establishment or the place of effective management. If strategic decisions are made from an office in France, and if contracts are negotiated and signed there, the tax authorities may argue that the company is taxable in France despite its Mauritian registration . The concept of a dependent agent applies in the same way when a French intermediary regularly acts on behalf of the company.
The process is never merely documentary. It consists of aligning operational reality with the legal structure: a manager actually present, advice provided on-site, local tools and bank accounts, and Mauritian service providers. Any structure lacking genuine economic substance is liable to be reclassified, and we do not support it.
Billing French clients from Mauritius
A Mauritian company can perfectly well invoice French companies. The practice is legal and common, provided that the service is actually performed from Mauritius and that the invoice reflects the economic reality. The issue, therefore, is not the legality of the transaction itself, but its location .
For value-added tax (VAT) purposes, a service provided between businesses to a French client by a service provider established outside the European Union falls under the reverse charge mechanism for the French recipient. Your invoice will be issued without Mauritian or French VAT, and it is your client who declares the tax. This mechanism must be clearly stated on the invoice, along with a mention of the applicable reverse charge mechanism .
For individual customers, the logic differs and depends on the nature of the service, particularly for electronic services. Furthermore, intermediary platforms have their own obligations to report income to European tax authorities under the DAC7 directive. Transactions passing through a platform are therefore visible to the relevant authorities , which argues for complete consistency between French and Mauritian tax returns.
The real risk isn't the invoice, it's the concentration of ties. A service provider who maintains an office in France, an exclusively French clientele, and frequent travel within France presents a number of unfavorable indicators. The same reasoning applies to a French resident's declaration in Cyprus , where the issue of a permanent establishment arises in very similar terms.
Terminating French tax residency: the four criteria
This is the crucial step, and the one upon which the other three steps are based. Article 4 B of the French General Tax Code establishes four alternative criteria for French tax residency: home, principal residence, principal professional activity, and center of economic interests. The key word is "alternative": meeting only one criterion is sufficient to maintain your French residency, regardless of your Mauritian status.
The term "home" refers to the family's usual place of residence, and this often takes precedence over the number of days worked. Having a spouse and children residing in France is a strong indicator of maintaining a French home, even if you yourself spend most of the year in Grand Baie. The primary residence is only a secondary consideration if no other identifiable home is found.
Center of economic interests and cluster of indicators
The center of economic interests is the criterion that most often blocks seemingly clean applications. The tax authorities examine where your main investments are located, the headquarters of your business, the source of the majority of your income, and the location where your assets are managed. An executive based in Mauritius but whose main income comes from a French holding company may find their center of economic interests maintained in France .
When both states consider each other as the state of residence, the Franco-Mauritian convention applies successive tie-breaker rules: permanent home, then center of vital interests, then habitual residence, and finally nationality. These rules are decisive, but they are supported by documentation. A properly prepared French resident declaration in Mauritius anticipates these issues instead of discovering them during an audit.
In practical terms, the year of departure requires a specific declaration, followed by registration with the non-resident tax office for subsequent years. If you hold securities exceeding the legal thresholds, form 2074-ETD relating to exit tax applies, and a payment deferral must be requested according to the proper procedures .
The installation component: housing, banking, family, health
The installation is not merely the logistics of the project; it is its proof. Every physical element you put in place in Mauritius contributes to demonstrating your community center, and every element you leave behind in France contributes to demonstrating the opposite. This is why this aspect must be treated with the same rigor as the tax aspect .
Housing is paramount. A long-term lease or a purchase in a program open to non-citizens provides a much more solid asset than a series of short-term rentals. If you retain a property in France, ensure that it is not at your permanent and exclusive disposal, as this constant availability reinforces the concept of a home .
Banking, education and health: the three details that speak volumes
Opening a Mauritian bank account and transferring your current accounts to it is a very clear indicator. Maintaining a French account is neither prohibited nor suspicious in itself, but your primary account must be transferred to Mauritius if that is where you reside.
Children's schooling in Mauritius carries more weight than any certificate. Having children still attending school in France is one of the most unfavorable indicators for your application. Regarding healthcare, leaving the French system and subscribing to international or local insurance further strengthens your case, demonstrating that your social ties have genuinely changed countries .
The question of lifestyle remains. Frequent trips back and forth to France, especially if they follow a work schedule, weaken the application even when the number of days worked is still favorable. It's better to reduce the frequency than to manipulate the system , because the administration considers a range of factors rather than pure arithmetic.
Reverse planning and comparison with other jurisdictions
A well-executed Mauritian project typically spans six to twelve months. The first three months are dedicated to scoping the project: auditing the four French criteria, inventorying assets, selecting a Mauritian vehicle, and deciding on French housing. The following months are devoted to submitting the permit application, establishing the business, and gradually transferring operations, with a departure date chosen rather than imposed .
The table below compares Mauritius to two useful benchmarks: the United Arab Emirates, our most popular destination, and France. These are general figures intended for contextualization, not a projection of your actual workload.
Setting | MAURITIUS | United Arab Emirates | France |
Corporate tax | 15% common law | 9% above the threshold | 25% common law |
Income tax | Progressive scale, marginal around 20% | No personal tax | Progressive scale up to 45% |
Capital gains on securities | Not taxed locally | Not taxed locally | Flat-rate deduction of 30% |
Inheritance rights | None | None | Progressive scale by link |
Wealth tax | None | None | IFI on French real estate |
VAT | 15% | 5% | 20% normal rate |
Attendance required | 183 days or 270 cumulative days | Variable depending on the visa | Alternative criteria article 4 B |
The differences shown in this table explain why comparisons rarely focus solely on income tax. The United Arab Emirates offers zero personal income tax but a different cultural distance and cost of living, while Mauritius offers a French-speaking environment, a moderate time difference, and low, though not zero, taxation. The decisive factor is often the quality of life compatible with a physical presence for more than half the year.
Alternatives to consider before making a decision
Several jurisdictions cater to similar profiles and deserve to be compared based on their specific circumstances. A French residency declaration in Andorra would suit those who wish to remain close to Europe, while a French residency declaration in Singapore is more suited to entrepreneurs whose markets are Asian. The choice is based on four key factors: tax burden, physical presence requirements, access to banking services, and compatibility with your family life .
One final methodological point: never base your decisions on a generic ranking found online. Two executives with the same income, but one owning a French property and the other not, will reach opposite conclusions. The answer depends on the individual circumstances , and only a case-by-case analysis can provide a definitive answer.
Testimony of an entrepreneur based in Mauritius
Anonymized profile: manager of a digital services company, 44 years old, married, two children, diversified European clientele, based in the north of the island for two financial years.
"I had approached the project from the company perspective, because that was the part I thought I understood. I was made to start from the other direction, beginning with the permit and the actual move of the family ."
"The one thing I hadn't foreseen was the schooling. As long as the children remained enrolled in France, my entire case rested on sand, regardless of the number of days I spent in Mauritius."
"I also underestimated the substance expected from my GBC: local board meetings, resident directors, real local spending. It's not a formality but an organization to be built ."
"Today the case holds up because it is documented month by month. I keep my boarding passes, my Mauritian statements and the minutes of council meetings, and I know exactly what I would produce if questioned."
This testimony illustrates an individual situation and does not constitute a promise of results or advice applicable to another case.
Frequently Asked Questions
How many days do you need to spend in Mauritius to be considered a tax resident?
Mauritian law recognizes two alternative tests: at least 183 days of presence during the tax year, or at least 270 cumulative days over three consecutive tax years. Meeting either of these tests makes you a resident of Mauritius, but it does not automatically remove you from French tax residency, which is governed by its own criteria.
Is it possible to keep a property in France after moving to Mauritius?
Yes, owning property in France is not prohibited and is not sufficient on its own to maintain French tax residency. The crucial point is the permanent and exclusive availability of the property, which can be used to establish a primary residence. Renting to a third party or documented occasional use changes the analysis.
Should you choose a GBC or an Authorised Company?
It all depends on the intended use. If you want to be able to invoke the Franco-Mauritian convention, only a Global Business Company, resident in Mauritius, allows this. An Authorized Company is treated as non-resident and must be managed from abroad, which excludes it from most personal expatriation projects.
Are the rents from a French property still taxed in France?
Yes. Rental income from French sources remains taxable in France for a non-resident, with a minimum tax rate applied unless a more favorable average rate can be demonstrated. Furthermore, a Mauritian resident is subject to social security contributions at the full rate; the reduced solidarity levy is reserved for those affiliated with a European social security scheme.
Does the exit tax apply when departing for Mauritius?
This may apply if you hold shares exceeding the legal thresholds at the time of transferring your tax residence. A deferral of payment is possible, but it must be requested according to specific procedures and deadlines. This matter must be resolved before departure, never after.
Is it possible to prepare for an expatriation to Mauritius in a few weeks?
It's technically possible to obtain a permit, but rarely prudent from a tax perspective. Meeting the four French criteria, compiling the evidence file, and establishing the Mauritian substance all take several months. A timeframe of six to twelve months remains the most justifiable.
Conclusion
A successful expatriation to Mauritius isn't necessarily one with the lowest tax rate, but rather one that withstands scrutiny three years later. The four key elements work together: Mauritian taxation provides the framework, the company offers the tools, residency grants status, and settling in demonstrates that the center of life has shifted .
The three mistakes we most often correct are the same: setting up the business before relocating, confusing the Mauritian residency certificate with leaving French residency, and neglecting family ties remaining in France. None of these mistakes is irreparable, but all are more expensive to correct than to prevent .
If you're still hesitating between several destinations, the method remains the same: calculate your actual spending patterns, assess the required presence, and verify family compatibility. A French residency declaration in Malta and a move to Mauritius are not comparable, and only a comparative review of documents will allow you to make a decision.
Finally, let us reiterate one last time: the rates, thresholds, and timeframes mentioned here are general guidelines that may change, and the applicable answer to your specific case depends entirely on your personal circumstances. Only an individual assessment can provide a definitive answer .
