Becoming a Tax Resident in Mauritius: Conditions and Procedures

Becoming a tax resident in Mauritius attracts a growing number of entrepreneurs, retirees and investors each year, drawn by the island's light taxation and quality of life. But between a simple tourist stay, obtaining a residence permit and official recognition of tax resident status by the Mauritius Revenue Authority (MRA), confusion is widespread. A Premium Visa or an Occupation Permit is not, on its own, enough to shift your tax position to the island.

The framework has also changed substantially: the Finance Act 2025 abolished the former eleven-band progressive scale, revised the thresholds for every permit issued by the Economic Development Board (EDB) and introduced an additional contribution for high earners. This guide sets out, point by point, the legal conditions to meet in 2026 — including the well-known 183 and 270-day presence thresholds — the permits available, the tax regime that genuinely applies, and the concrete steps to obtain your Tax Account Number (TAN) and then your Tax Residence Certificate (TRC) from the MRA.

Tax residency in Mauritius: what exactly are we talking about?

Residency, residence permit and tax residency: don't confuse them

Before going further, it is essential to clear up a very common confusion. Spending a few weeks in Mauritius, obtaining a residence permit and becoming a tax resident are three entirely distinct legal realities, even if readers often conflate them.

• A simple stay: remaining on the island as a tourist, with no particular rights and no local tax obligations.
• A residence permit: an administrative authorisation allowing you to live legally on Mauritian territory, for professional, family or investment reasons.
• Tax resident status: a precise tax qualification, based on criteria of length of presence and centre of economic interests, which determines where you must declare and pay your taxes.

Understanding this distinction is the key to approaching any relocation strategy with confidence. No Mauritian tax advantage applies until tax residency has actually been established.

Why Mauritius attracts expatriates and investors

Mauritius appeals to more French nationals and expatriates from around the world every year. This success is explained by a pleasant tropical climate all year round, political and economic stability that is rare in the region, and a tax framework that — even after the 2025 reform — remains markedly lighter than European standards: the Mauritian scale is capped at 20%, against 45% in France.

The sections that follow detail the legal conditions to meet, the various permit types and their updated thresholds, the tax rules applicable since July 2025, and the concrete steps to settle in and obtain tax resident status in Mauritius.

The legal conditions for being treated as a tax resident

The Mauritius Revenue Authority (MRA) applies three distinct legal tests to determine whether an individual should be treated as tax resident in Mauritius. These criteria are alternative: meeting any one of them is enough to trigger the qualification, without needing to satisfy the others.

The 183-day test

The first criterion applied by the MRA is continuous or cumulative physical presence of at least 183 days on Mauritian territory, calculated over a given tax year. For this calculation, the day of arrival and the day of departure each count as a full day of presence, whatever the actual landing or departure time. A stay split across several return trips can therefore reach the 183-day threshold provided all periods are added up rigorously. Always keep your boarding passes and passport stamps: the burden of proof falls on you.

The 270-day test over three years

The second test looks at presence of at least 270 cumulative days across the tax year concerned and the two preceding tax years. Watch out for a frequently mangled formulation: this is not the three years preceding the current one, but the current year added to the two before it. This mechanism allows the MRA to treat as tax resident an individual whose presence is irregular from year to year but significant over the medium term. The counting method is identical: every day of entry into and exit from the territory is counted in full, with no hourly pro-rating.

The domicile and centre of vital interests criterion

Beyond the day count, the MRA also examines:

• the person's main and permanent place of residence
• the location of their immediate family and personal ties
• the centre of their economic and professional activities
• clear intent to reside on the island on a lasting basis

The Mauritian tax year runs from 1 July to 30 June, an essential detail for correctly situating the reference periods used in these three tests. Note finally that the MRA may require 183 days of actual presence before issuing a TRC intended for a foreign tax administration, even where the 270-day test is theoretically satisfied.

Overview of the permits granting residency in Mauritius

The Economic Development Board (EDB) issues several categories of residence permit tailored to varied profiles: working professionals, investors, retirees or family members. Each status answers to precise financial and administrative criteria, entirely revised by the Finance Act 2025 and the guidelines of 19 August 2025, which should be compared before choosing the route best suited to your situation. All applications now go through the NELS portal (National Electronic Licensing System), and a non-refundable USD 50 application fee has applied since 1 December 2025 to any residence or stay permit application.

Occupation Permit: work and investment

The Occupation Permit is aimed at those wishing to work or do business in Mauritius. Combining residence and work rights, it comes in three distinct profiles whose thresholds have been substantially reworked:

• Investor: two routes have coexisted since 2025. The standard route rests on an initial contribution of USD 50,000, with turnover of at least MUR 1.5 million in the first year and MUR 20 million cumulatively over five years. The premium route requires USD 100,000 but relaxes performance targets, which suits start-ups and gradual projects. A mid-term review clause has been introduced: the EDB checks commitments after five years, and a minimum annual threshold of MUR 5 million applies from the sixth year. The permit runs for 10 years, renewable.
• Professional: the former single threshold has given way to a two-tier system. The ProPass requires a basic monthly salary of at least MUR 30,000 and covers most qualified managers and specialists. The Expert Pass, a premium category aimed at senior executives and highly specialised consultants, requires a basic monthly salary of at least MUR 250,000. Both tiers grant a 10-year permit.
• Self-Employed: initial investment raised to USD 50,000 (from USD 35,000), three letters of intent including two from Mauritius-based clients, turnover of at least MUR 750,000 in the first year and MUR 6 million cumulatively over five years. The permit duration has been reduced to 5 years, renewable.

Renewal remains conditional on maintaining the financial thresholds set by the EDB. Note too that moving up to the Permanent Residence Permit, valid for 20 years, now requires having held an Occupation Permit for at least five years, against three before the reform.

Retired Non-Citizen Permit: the retiree route

Aimed at people over 50 wishing to settle in Mauritius without carrying on local professional activity, the Retired Non-Citizen Permit requires an initial transfer of at least USD 2,000 into a Mauritian bank account within sixty days of the permit being issued, followed by regular transfers of at least USD 2,000 per month, or USD 24,000 per year, from foreign sources. Valid health cover is also required. The permit is issued for ten years, with periodic verification of the funds transferred to Mauritius to secure renewal.

Some commercial sources still quote the former threshold of USD 1,500 per month: always have the amount applicable to your file confirmed by the EDB before committing.

Family Occupation Permit and Dependent Permit

The holder of an Occupation Permit or a Retired Non-Citizen Permit can extend their status to their family through the Dependent Permit, covering:

• the spouse and dependent children under 24
• dependent parents, subject to conditions

The validity of this family residence permit is aligned with that of the main permit, with simultaneous renewal to guarantee continuity of status for the whole household. Each dependant is the subject of a separate application on NELS, with the corresponding fees.

Premium Visa and residency through property investment

Premium Visa: a stay permit, not tax residency

The Mauritian Premium Visa appeals to many remote workers and entrepreneurs wanting to test a move to the island. Free of charge and processed within a few days, it allows a stay of one year, renewable once, i.e. two years maximum consecutively. It requires income of at least USD 1,500 per month from exclusively foreign sources and does not permit working for Mauritian clients or employers. Beyond two years, you must switch to another status: Occupation Permit, Retired Non-Citizen Permit, or a residence permit tied to a property purchase.

One confusion persists, however: holding a Premium Visa does not make you a Mauritian tax resident. This status is merely an administrative authorisation to stay, distinct from the tax criteria based on the number of days of actual presence on the territory. Below 183 days per tax year, you remain a non-resident for Mauritian tax purposes, whatever your visa. It is therefore essential not to equate the mere ability to reside physically on the island with genuine tax resident status, which carries very different legal and tax consequences, particularly on income reporting.

A point to watch in 2026: several reports from the ground suggest that Premium Visa renewals are being phased out. Check the state of the scheme with the EDB before making it the pivot of your project.

Investing in property (PDS, IRS) to obtain permanent residency

For more solid permanent residency, property investment is a preferred route. The PDS (Property Development Scheme) and Smart City Scheme programmes and, on the resale market, IRS and RES, allow foreigners to acquire property from USD 375,000 — the threshold granting a residence permit tied to the property. The permit remains valid for as long as the property is held, offering lasting stability with no repeated formalities. Note that the IRS has accepted no new projects since 2015: it survives only on resale.

• Buying a villa or apartment in sought-after areas such as Grand Baie, prized for its energy and seaside life
• Investing in Flic en Flac, known for its beaches and upmarket residential setting
• Benefiting from a residence permit attached to the property, extendable to immediate family

One major budget factor took effect on 1 July 2026: registration duty payable by a non-citizen buyer rose from 5% to 10%, bringing acquisition costs to roughly 12% to 15% of the price. This property strategy nonetheless provides a concrete base for eventually considering a genuine tax move to Mauritius.

Comparison table of permits and routes to residency

Each Mauritian permit answers to specific investment or income conditions, with its own administrative formalities. This summary comparison, updated in line with the August 2025 guidelines, makes it possible to quickly identify the route best suited to your profile before starting formalities with the Mauritian authorities.

Comparing investment thresholds and income requirements

The amounts required vary considerably by permit type, expressed in dollars or Mauritian rupees:

In every case without exception, obtaining the permit is not enough: tax residency remains conditional on actual physical presence in the country. Before choosing your route, check:

• The exact investment amount required for your personal situation
• The formalities to anticipate on the Economic Development Board's NELS portal
• The permit's compatibility with your long-term life plans

Duration, renewal and access to tax residency by permit

Validity directly determines the stability of your status. Property-linked permits offer maximum durability since they follow ownership of the asset, while the Premium Visa requires annual renewal capped at two years and the Self-Employed permit has gone from ten years to five. The Permanent Residence Permit, valid for 20 years, requires five prior years under an Occupation Permit. In all cases, meeting the 183-day annual threshold, or the 270-day cumulative one, remains the decisive rule for actually activating your tax residency and benefiting from the Mauritian regime.

Mauritian taxation: rates and applicable regime

The three-band progressive scale and the Fair Share Contribution

This is the most important change to know about, and the one most online content has yet to incorporate. The former eleven-band scale, like the flat 15% rate that preceded it, has been abolished. Since the income year opening on 1 July 2025, the Finance Act 2025 has applied a progressive scale with just three bands:

For example, a resident with MUR 800,000 of taxable annual income will pay nothing on the first MUR 500,000, then 10% on the next MUR 300,000 — MUR 30,000 of tax and an effective rate of 3.75%, well below their marginal rate.

On top of this scale sits the Fair Share Contribution, an additional levy introduced for high earners and set at 15% on the portion of taxable income exceeding MUR 12 million per year. It concerns only a minority of taxpayers, but should be anticipated by executives drawing high Mauritian-source remuneration.

The remittance basis for foreign income

Tax treatment differs sharply between local income and foreign-source income. The latter benefits from the remittance basis, maintained in 2026:

• Foreign income is taxable only when actually remitted to Mauritius
• Income kept abroad escapes Mauritian tax
• Only income remitted to a Mauritian bank account enters the taxable base

In practice, a resident receiving foreign dividends can optimise their tax burden by controlling the timing and amount of repatriations. This flexibility obviously does not remove the obligation to declare your full position or to meet the reporting requirements of your home country.

Tax advantages: no property tax and no inheritance tax

No wealth tax and no inheritance tax

Tax residency in Mauritius offers a particularly favourable framework for preserving and passing on wealth. Unlike many Western countries, the island levies neither wealth tax nor inheritance tax. This is a major advantage for residents holding substantial assets, whether property or financial.

• No wealth tax, whatever the value of the assets held
• No inheritance tax for Mauritian tax residents, easing transfers to heirs
• No capital gains tax for individuals, the levy raised in the 2025-2026 Budget having ultimately not been introduced in the Finance Act 2025
• Generally lighter taxation than European regimes, despite the reform of the scale

Council tax, property tax and local property taxation

Rental income received by Mauritian tax residents is subject to income tax under the progressive scale in force — 0%, 10% or 20% depending on the band: the flat 15% rate applied in the past no longer exists. That level nonetheless remains well below France, where combined taxation of rental income and social levies can exceed 40% for some taxpayers.

On local property taxation, Mauritius also stands out for its light burden: there is no property tax or council tax comparable to those levied in France, only moderate municipal taxes depending on the municipality. Owners therefore benefit from simplified asset management, without the recurring levies that traditionally weigh on property ownership in other jurisdictions.

The France–Mauritius double taxation treaty

Principle and operation of the tax treaty

The double taxation treaty signed between France and Mauritius is the legal foundation securing the position of French expatriates settled on the island. Its objective is simple: to prevent the same income being taxed twice, once in each country, and to determine clearly which State has the right to tax. For any French tax resident who has moved their residence to Mauritius, this treaty becomes an essential reference for organising reporting obligations with confidence.

Avoiding double taxation on your income

In practice, the treaty allocates taxing rights according to the nature of the income received. The main categories concerned are:

• Private-sector retirement pensions, taxable in the beneficiary's State of residence, therefore in Mauritius, with public pensions remaining subject to separate rules;
• Dividends, which may be subject to limited withholding tax in the country of origin, with a tax credit applicable elsewhere;
• Property income, taxed in the country where the asset is located, regardless of the owner's place of residence;
• Salaries, taxed in principle in the State where the professional activity is carried out.

To assert their rights, the taxpayer must produce a Mauritian tax residence certificate to the French administration and attach the appropriate supporting documents to their income tax return. Two points warrant attention: France may continue to levy social contributions on pensions paid by French schemes, and a Mauritian resident selling a property located in France remains taxable there on the capital gain. Where there is doubt about the application of a clause, it is advisable to seek support from a tax adviser familiar with the subtleties of this bilateral treaty.

Practical steps to obtain tax resident status

Obtaining a Tax Account Number (TAN) from the MRA

The first administrative step is to obtain a Tax Account Number from the Mauritius Revenue Authority, the body responsible for taxation in Mauritius. This tax identification number is essential for all subsequent formalities, and in particular for your future income tax return.

• Step 1: Gather the required supporting documents: valid passport, Mauritian residence permit, recent proof of address (electricity bill or lease) and proof of income (employment contract, payslips or pension statement).
• Step 2: File a TAN application online via the MRA portal or directly at their offices in Port Louis.
• Step 3: Allow for processing time, generally between one and two weeks depending on the complexity of the file.
• Step 4: Open a local bank account, often required in parallel or just after the TAN is issued, since it is a prerequisite for domiciling income and greatly facilitates dealings with the tax administration.

Applying for your Tax Residence Certificate (TRC)

Once the TAN has been obtained, the Tax Residence Certificate application can be started. This official document attests to your Mauritian tax resident status and allows you to benefit from international tax treaties.

• Step 1: Assemble a complete file including the TAN, proof of actual stay in Mauritius (183 days minimum over the year) and evidence of income received.
• Step 2: Submit the TRC application to the MRA, together with Mauritian bank statements and, where applicable, the lease or title deed registered with the Registrar General.
• Step 3: Allow an average processing time of two to four weeks before receiving the certificate.
• Step 4: Repeat this process each tax year to retain the benefits.

Filing your income with the Mauritius Revenue Authority

Once tax resident status has been established in Mauritius, every taxpayer must meet their reporting obligations with the Mauritius Revenue Authority (MRA), the Mauritian tax administration. This applies both to individuals receiving local or foreign income and to company directors subject to corporate tax. The MRA has developed an online portal allowing returns to be submitted digitally, securely and quickly, reducing traditional administrative formalities.

Annual filing calendar and procedures

The Mauritian tax year runs from 1 July to 30 June. Residents must observe a precise calendar to avoid difficulties:

• Filing the income tax return: before 30 September following the close of the tax year
• Payment of tax due: at the same time as the return is filed
• Quarterly returns for certain categories of company (Advance Payment System)

Penalties and compliance obligations

Failure to meet deadlines results in financial penalties and late interest calculated on the unpaid tax. Beyond the financial aspect, repeated non-compliance can undermine recognition of tax resident status and complicate future dealings with the Mauritius Revenue Authority. It is therefore advisable to anticipate your obligations, keep the necessary supporting documents — particularly proof of physical presence — and, if needed, engage a local professional to secure your tax position.

Frequently asked questions

Can you be a Mauritian tax resident while keeping ties with France?

Yes, it is possible to keep assets, family or income in France while being tax resident in Mauritius, provided you do not retain your main tax household in France. The double taxation treaty between the two countries determines precisely which State is competent to tax each category of income and avoids double taxation. Be aware, however, that selling a property located in France remains taxable in France.

How many days do you need to spend in Mauritius to become a tax resident?

The MRA applies two physical presence criteria: the 183-day test over the current tax year, or the 270-day test over the current year and the two preceding years. Meeting either threshold is sufficient, subject to the other personal connection conditions. Note that the MRA may require 183 actual days before issuing a TRC intended for a foreign administration.

Does the Premium Visa grant Mauritian tax residency?

No, the Premium Visa is only a one-year stay permit, renewable once, with no automatic link to tax residency. To be recognised as a tax resident by the MRA, you must meet the 183 or 270-day physical presence criteria, regardless of the type of permit held. In 2026, uncertainty also surrounds the continuation of renewals for this visa.

What is the minimum amount to invest in property to obtain a residence permit?

The Economic Development Board requires a minimum property investment of USD 375,000 in an eligible development — PDS, Smart City, or IRS and RES on the resale market — to obtain an associated residence permit. This threshold governs the grant of the permit but does not on its own guarantee tax resident status. Since 1 July 2026, registration duty of 10% must also be factored in.

What happens if you lose your Occupation Permit or Retired Non-Citizen Permit?

Losing or failing to renew an Occupation Permit or a Retired Non-Citizen Permit means losing the right to stay in Mauritius and, consequently, the ability to continue meeting the physical presence criteria needed to maintain tax resident status, forcing you to leave the country or regularise your position quickly. Since the 2025 reform, the EDB's mid-term reviews make this risk more concrete for investor permit holders.

How do you obtain a Tax Residence Certificate (TRC) in Mauritius?

The Tax Residence Certificate is obtained from the Mauritius Revenue Authority after demonstrating compliance with the tax residency criteria — physical presence and personal connection — and after first obtaining a Tax Account Number. This official certificate attests to your tax status, is renewed annually and allows you, among other things, to invoke the double taxation treaty.

Conclusion

Becoming a tax resident in Mauritius means clearly distinguishing administrative residency, the stay permit and tax residency in the strict sense, recognised by the MRA through the 183 and 270-day tests. The choice of permit — the Occupation Permit in its three reworked forms, the Retired Non-Citizen Permit, or property investment via the EDB — deserves careful thought based on your profile, as do the steps to obtain the TAN and then the TRC.

With a scale capped at 20%, the remittance basis maintained, no inheritance tax and a double taxation treaty with France, Mauritius remains an attractive tax destination. But the framework has tightened: new permit thresholds, a Fair Share Contribution of 15% above MUR 12 million, and registration duty doubled for foreign buyers. Since every situation is unique, working with professionals specialising in relocation to Mauritius helps secure your change of tax residency and avoid costly administrative mistakes.
