Becoming a tax resident in Mauritius is not simply a matter of “living on the island”.
To be considered Mauritian tax resident, it is necessary to respect the specific criteria (including attendance thresholds) and understand how this affects your taxes, tax returns, and foreign income. In this guide, EXPAT MAURITIUS helps you see things clearly, avoid common mistakes and secure your settlement (visa/permit, accommodation, bank, schooling, business creation) with local and coordinated support.
1) Tax residence in Mauritius: what exactly are we talking about?
Tax residency vs. permit (immigration): two different concepts
There tax residence determined Or you are taxed and according to what rules. It is not automatically identical to your immigration status (Occupation Permit, Residence Permit, etc.). In practice, the Mauritian tax authorities rely on criteria of presence and/or domicile to determine tax residency.mra.mu)
Note the calendar: the Mauritian fiscal year is not the same as the calendar year.
In Mauritius, the’income year (fiscal year) short of July 1st to June 30th. This is a crucial point for your calculations of days, your declarations and, if necessary, the validity of a Tax Residence Certificate (TRC). (eservices3.mra.mu)
2) The official criteria for being a tax resident in Mauritius (natural persons)
An individual is considered to be resident in Mauritius for a tax year if he fulfills at least one of the following criteria:
- Residence in Mauritius (unless your permanent place of abode is abroad); ;
- Presence in Mauritius at least 183 days for the relevant fiscal year; ;
- Cumulative attendance at least 270 days for the relevant fiscal year + the previous 2 tax years.
These definitions are included in the documents and resources of the Mauritius Revenue Authority (MRA). (eservices3.mra.mu)
How to count the days (and why it's a source of errors)
In practice, the “day count” can become the number one pitfall: a misunderstanding of the July 1st (beginning of fiscal year) or an approximate tracking of entries/exits can cause you to switch from one status to another.
Furthermore, certain market practices and guides remind us that the arrival and departure days are generally counted as days worked. As a precaution, always keep a travel history (stamps, boarding passes, booking emails).newhorizon-mauritius.com)
Concrete example: 183 days… but over what period?
You arrive in Mauritius on August 15, 2025. The current fiscal year ends on June 30, 2026. Depending on your pace of stay, you may (or may not) reach the 183 days before June 30th. If you are aiming for tax residency for the 2025/2026 tax year, you must consider on this window 01/07/2025 → 30/06/2026, not for the calendar year 2025. (mra.mu)
3) What are the tax implications of being a resident in Mauritius?
Taxable income: Mauritius + foreign income "remitted" to Mauritius
According to the MRA, once the residency criteria are met, the resident is taxable in Mauritius on their income. derivatives in Mauritius Or remitted to Mauritius (remitted/repatriated to Mauritius). Non-residents are taxed only on Mauritian-source income and do not benefit from the same relief/deductions.mra.mu)
Common pitfall: confusing “transferred money” and “capital”. Case law and market analyses show that the tax authorities can consider as taxable sums that retain their nature of income when they are handed over to Mauritius, depending on the circumstances. Have your situation (income, savings, dividends, pensions, etc.) reviewed by a professional.forvismazars.com)
Income tax scale (effective from July 1, 2025)
The MRA indicates that from July 1, 2025, the taxation of individuals on the chargeable income is structured as follows: 0% on the first Rs 500,000, 10% on the Rs 500,000 following, then 20% about the rest. (mra.mu)
Fair Share Contribution (high income): something to be aware of if you exceed Rs 12 million
The 2025/2026 Budget introduced a Fair-Share Contribution for some high earners: beyond Rs 12 million of net annual income (including domestic dividends), a contribution applies, collected via the PAYE system, for a stated period of 3 fiscal years starting from July 1, 2025. Further details also exist for higher income levels (e.g., above Rs 24 million).pwc.com)
Reporting obligations: deadlines, penalties, and points to be aware of
The MRA publishes due dates For the electronic filing of individual declarations, the standard deadline is the September 30, with an extension to October 15 subject to conditions (including online declaration and payment methods).mra.mu)
In practice, the MRA's e-services page also reminds users of... penalties in case of delay (e.g., monthly penalty, cap, late payment penalty, interest).eservices.mra.mu)
4) The Tax Residence Certificate (TRC): what is it for and when should you apply for it?
TRC: the document that “proves” your tax residency
THE Tax Residence Certificate (TRC) is issued by the MRA and is often used to prove your tax residency to foreign administrations, banks or partners, particularly for the application of tax treaties. The MRA states that if a person wishes to be certified as a resident for a year, they must apply for it.mra.mu)
Duration/alignment with the fiscal year and fees
For the individuals, The MRA specifies that the validity of the TRC must be aligned with the fiscal year (July 1 – June 30) and indicates a TRC service fee of WALL 1000 for individuals. (eservices3.mra.mu)
Where to apply / who to contact
The application is made via the dedicated e-services platform, and the MRA provides the contact details of the unit in charge (International Taxation Unit / Large Taxpayers Department) for support. (eservices3.mra.mu)
5) Tax treaties and automatic exchange of information: what to anticipate
Double taxation avoidance agreements: Mauritius has a significant network
The MRA indicates that Mauritius has concluded 46 tax treaties (conventions) and publishes the list of agreements in force, as well as treaties under negotiation and certain historical terminations. This is a key point if you want to avoid a double residence or a double taxation (depending on your country of origin).mra.mu)
CRS (automatic exchange): transparency is the norm
Maurice is participating in the’Automatic Exchange of Information within the framework of Common Reporting Standard (CRS). Evaluations and publications related to this system confirm that Mauritius exchanges financial information with partners, and the OECD documents the CRS exchange framework. In other words: compliance (declarations, consistency of statutes, supporting documents) is not optional.oecd.org)
6) Traps to avoid (and how to neutralize them)
- Choosing the wrong tax year (Calendar year vs. 01/07–30/06): Plan your stays and objectives using the correct calendar. (eservices3.mra.mu)
- Counting the days "roughly"“ : keep an attendance sheet (stamps, tickets, reservations, entry/exit history).
- Confusing tax residence and permit Immigration status alone is not sufficient, and the reverse is also true in some cases (e.g., teleworking, stays).mra.mu)
- Ignoring the “remittance” rule” Transfers, deposits, local payments… tax classification depends on the facts.mra.mu)
- Forget about MRA deadlines Plan ahead for filing your tax return and making payments, especially if you have multiple sources of income.mra.mu)

The rule of 183 days is calculated based on the Mauritian tax year (01/07–30/06), which often surprises newcomers. For the exact calculation of the days and the tax impact according to your income (Mauritius/foreign), it is recommended to consult a tax professional.mra.mu)
Is a Tax Residence Certificate (TRC) mandatory to be a tax resident?
Not necessarily. One can be a tax resident. by applying the criteria (183 days, 270 days/3 years, home) without immediately requesting a TRC. However, the TRC is often requested by a bank or foreign administration to apply a tax treaty or justify your status. The MRA also specifies practical elements: validity aligned with the tax year and fees for individuals.mra.mu)
Does EXPAT MAURITIUS intervene regarding MRA tax returns and deadlines?
EXPAT MAURITIUS positions itself first and foremost as a expatriation consultant (installation, procedures, coordination), which greatly helps in gathering the necessary documents and avoiding mistakes.

For an optimized and compliant declaration (especially with foreign income), the support of an accountant is often relevant.mra.mu)
If I transfer foreign income to a Mauritian account, is it taxable?
The MRA indicates that a resident will be taxed on income derived in Mauritius or remitted to Mauritius. In practical terms, certain transfers/repatriations may trigger taxation depending on the nature of the funds and your situation. This is a sensitive point: the classification of "income vs. capital/savings" and traceability are very important. Before making significant transfers, have your situation reviewed (source of funds, periods, agreements, supporting documents).mra.mu)
Why do banks ask for so much information (status, tax residence, country)?
Because Maurice is participating in the’automatic exchange of information (CRS/AEOI). Financial institutions must identify the tax residence(s) of clients, collect information and, in some cases, report to the tax authorities, who then exchange information with partners. This makes the consistency of your file (address, presence, TRC if necessary, declared country of tax residence) particularly important.oecd.org)
