Tax Residency in Mauritius

What is tax residency?

Tax residency determines in which country an individual is liable for tax on their worldwide income. It is a concept distinct from a residence permit (immigration) and nationality. A person may hold a residence permit in a country without being tax resident there, and vice versa.

Tax residency is a fundamental issue for international entrepreneurs and investors wishing to relocate to Mauritius. It determines the tax framework applicable to all your income -- salaries, dividends, interest, capital gains, rental income -- as well as the tax treatment of your wealth (inheritance, gifts, assets). Your choice of tax residency also conditions your access to double taxation avoidance agreements and your ability to structure your wealth effectively.

Disclaimer: the transfer of tax residence is an operation with major consequences that must be planned with qualified tax advisors in both jurisdictions concerned. Sunibel Corporate Services directs you to the relevant professionals and supports you with the Mauritian-side procedures.

Tax residency criteria in Mauritius

Mauritian tax law, as defined by the Income Tax Act, uses several criteria to determine the tax residency of an individual:

The 183-day rule

An individual is considered tax resident in Mauritius if they are present on the territory for at least 183 days during a tax year (1 July to 30 June). This is the most commonly used quantitative criterion.

The cumulative presence criterion

An individual is also tax resident if they have been present in Mauritius for at least 270 days over the two preceding tax years combined, and are present in Mauritius during the current tax year. This criterion covers situations of regular but sub-183-day presence in a single year.

The domicile criterion

An individual whose domicile is in Mauritius (in the sense of permanent home, household, centre of vital interests) may be considered tax resident even if they do not strictly satisfy the 183-day criterion. This qualitative criterion is assessed on a case-by-case basis.

Tie-breaker rules

When an individual is considered tax resident by both Mauritius and another country with which Mauritius has signed a double taxation avoidance agreement, the treaty's tie-breaker clauses apply to determine a single state of tax residence for treaty purposes. The tie-breaker criteria are, in order:

1. Permanent home: the country where the person has a permanent dwelling
2. Centre of vital interests: the country with which personal and economic ties are closest
3. Habitual abode: the country where the person stays most frequently
4. Nationality: as a last resort, nationality may serve as a tie-breaker

Taxation of residents

Mauritian tax residents benefit from a particularly attractive tax framework. For corporate taxation, see our dedicated guide. Here are the main advantages for individuals:

• Income tax: maximum rate of 15%, applied on a progressive scale with exempt bands and personal deductions
• No capital gains tax for individuals on the disposal of securities
• No wealth tax
• No inheritance tax or gift tax
• No withholding tax on dividends received from Mauritian companies

Treatment of foreign-source income

Mauritian tax residents are in principle taxed on their worldwide income. However, the treatment of foreign-source income has important specificities. Certain categories of foreign income may benefit from favourable treatment, particularly when not remitted to Mauritius, subject to conditions and depending on the nature of the income concerned.

It is essential to note that Mauritian tax legislation is subject to change, and the exact treatment of each income category depends on the individual situation of the taxpayer. A personalised analysis by a tax advisor is essential.

Advantages for entrepreneurs

For an entrepreneur holding a company in Mauritius (whether a GBC or a local company), aligning personal tax residence with the company's jurisdiction presents several structural advantages:

• Simplified structure: a single legal and tax framework to manage, reducing complexity and compliance costs
• Strengthened substance: the physical presence of the director in Mauritius reinforces the company's economic substance and its credibility with tax authorities and banks
• Access to tax treaties: tax residency in Mauritius provides access to the benefits of the 44+ double taxation avoidance agreements signed by the country, at both personal and professional levels
• Dividend distribution: dividends paid by a Mauritian company to a Mauritian tax resident are subject to no withholding tax and are exempt from tax at the recipient level
• Consistency for third parties: commercial partners, banks and investors value the consistency between the director's place of residence and the company's jurisdiction

Filing obligations

Mauritian tax residents are subject to the following filing obligations:

• Annual tax return: to be filed with the MRA by no later than 30 September of the year following the tax year. The return covers all worldwide income
• Tax payment: tax due is payable at the time of filing, or by provisional instalments (APS -- Advance Payment System) for taxpayers meeting certain conditions
• Declaration of foreign accounts and assets: tax residents must declare their bank accounts and assets held abroad, in accordance with applicable transparency obligations

Tax treaties and residence

Mauritius has concluded over 44 double taxation avoidance agreements with countries worldwide, including France, the United Kingdom, India, South Africa, China, Germany, Luxembourg and Singapore. These agreements are an essential tool for international tax planning.

The TRC for individuals

To benefit from the advantages of a tax treaty, a Mauritian tax resident must obtain a Tax Residence Certificate (TRC) from the MRA. This certificate attests to effective tax residence in Mauritius for a given tax year. It is presented to the tax authorities of the other contracting state to request the application of reduced rates or exemptions provided by the treaty.

Avoiding double taxation

Treaties provide mechanisms to eliminate double taxation: tax credit (crediting of tax paid in the other state) or exemption (certain income is only taxable in one state). The applicable mechanism depends on the specific treaty and the type of income concerned.

Wealth planning

The transfer of tax residence to Mauritius is often part of a broader wealth planning approach. The absence of wealth tax, inheritance tax and capital gains tax provides a favourable framework for structuring and transmitting wealth.

• Asset structuring: organising wealth between personal assets, holding companies and investment vehicles within a coherent tax framework
• Trusts: Mauritius has trust legislation (Trusts Act) enabling the establishment of asset protection and wealth transfer structures, supervised by the FSC. The Mauritian foundation is a recognised alternative for civil law jurisdictions
• Succession planning: in the absence of inheritance tax in Mauritius, wealth transfer can be optimised, subject to the potential application of succession rules in the country of origin of the heirs

Pitfalls to avoid

The transfer of tax residence to Mauritius carries real risks that must be anticipated:

• Maintaining ties with the former jurisdiction: keeping a dwelling, an office, active bank accounts or professional activities in the country of origin may compromise the transfer of tax residence and maintain a tax obligation in that country. The break must be effective and documented
• Substance of stay: being tax resident in Mauritius requires genuine and regular physical presence on the territory. Tax authorities in countries of origin closely examine evidence of effective residence (flight tickets, local bank statements, rental contracts, subscriptions, social activity)
• Exit tax and obligations in the country of origin: France, for example, applies an exit tax on unrealised capital gains of taxpayers transferring their tax domicile outside France, under certain conditions. Other countries have similar mechanisms. Compliance with these obligations before departure is essential
• Transitional filing obligations: most countries require a tax return for the year of departure, covering the period of residence. Failure to meet this obligation may result in penalties and disputes
• Anti-abuse rules: some countries apply presumptions of residence or anti-abuse rules targeting taxpayers who transfer their domicile to low-tax jurisdictions while maintaining substantial economic interests in the country of origin

Recommendation: the transfer of tax residence is an operation requiring rigorous preparation and guidance from tax law professionals in both jurisdictions concerned. Sunibel Corporate Services directs you to the relevant experts and supports you with the Mauritian-side administrative procedures.
