Tax residency in Mauritius is verified according to specific rules. In 2026, the core issues remain domicile, the 183-day threshold, the alternative of 270 days over two years, and the classification of income to be declared.mra.mu)
In other words, simply "living a little bit in Mauritius" is not enough to qualify as a tax resident. Your actual presence on the island, your administrative status, and, if necessary, requesting official proof of tax residency are all required.
What is a Mauritian tax resident?
According to the Income Tax Act 1995, an individual is considered a tax resident of Mauritius if they are domiciled in Mauritius, unless their permanent residence is elsewhere, if they have been present on the island for at least 183 days during the tax year, or if they have accumulated 270 days over the year in question and the two preceding years. The same legislation also provides for the possibility of applying for a Tax Residence Certificate with the Director-General, with issuance announced within 7 days if the administrative conditions are met.
Summary table of tax residency criteria
Here is a simple reading of the criteria to consider before concluding too quickly whether or not you are a Mauritian tax resident.
| Criteria | Threshold or logic | Practical effect |
|---|---|---|
| Residence | Residence in Mauritius, except for permanent place of residence located outside of Mauritius | This may be sufficient to bring the person within the scope of tax residency. |
| Annual attendance | 183 days or more in the tax year | The person is treated as a tax resident |
| Presence over several years | 270 days or more accumulated over the current year and the two preceding years | The person is treated as a tax resident even if they do not exceed 183 days each year. |
| Certificate of tax residence | Request to the Director-General of the MRA | Allows you to obtain official proof of tax status |
| Special case of the premium visa | Specific regime for amounts discounted in Mauritius | The tax treatment may differ from the standard resident regime |
Key takeaway: tax residency isn't just a matter of visas. It's a tax analysis based on your days of presence, your domicile, and, where applicable, your income deposited in Mauritius.
The 183-day rule: how to understand it without making a mistake?
The 183-day rule is the most well-known entry point, but it's not the only one. In practice, you need to consider the tax year as a whole and check whether your stay, even if it's split, puts you over the legal threshold. If you're close to the limit, the most important thing is to keep a rigorous record of your entries, exits, and periods of actual presence.
To avoid a misclassification, keep a consistent record of your travel, travel documents, and periods of residence. The clearer your residency file, the easier it will be to demonstrate your status in the event of an inspection or a request for a certificate.
What income is taxable for a tax resident in Mauritius in 2026?
The MRA indicates that a resident is taxed on income derived in Mauritius and on income deposited in Mauritius, and that they may be eligible for reliefs, deductions and allowances. In practice, the resident regime is therefore broader than a simple tax on local wages.mra.mu)
The MRA also specifies that the individual must complete a declaration if they are registered, if they have a chargeable income, if it exceeds certain net income thresholds, or if it receives income already subject to withholding. For the reference year 2025-2026, the published rates apply 0 % on the first Rs 500,000 of chargeable income, then 10 % on the next tranche and 20 % on the remainder. (mra.mu)
In practical terms, the income to monitor generally includes salaries, certain pensions, self-employment profits, rents, and, more broadly, income that falls within the Mauritian tax base. The key point is therefore not only where you live, but also knowing What income do you receive? And how they are treated fiscally.
Concrete examples of situations to analyze
- An expatriate employee who physically works in Mauritius must check whether their remuneration falls within the local taxable base.
- An entrepreneur who invoices from Mauritius must distinguish between income related to local activity and income that falls under other jurisdictions.
- A retiree living on the island should review the processing of their pension and, if applicable, any amounts deposited in Mauritius.
- An investor who receives rents or investment income should check whether this income is taxable under the Mauritian regime.
Residence permit, Occupation Permit and tax residency: these are not the same thing
The Passport and Immigration Office reminds foreigners that they can live, work, or retire in Mauritius through several channels, including the Occupation Permit, the Residence Permit, or other statuses tailored to individual circumstances. The Occupation Permit combines work and residence, while a Residence Permit may be granted in certain cases, particularly for non-citizen retirees over 50.passport.govmu.org)
In practice, this point is crucial: a migration permit facilitates your settlement, but it is not sufficient on its own to determine your tax status. You must always compare your permit, your days of presence, and your actual income with Mauritian tax regulations.
