Key Takeaways
- Company tax residency in Mauritius turns on incorporation and place of effective management, not paperwork alone.
- Individual residency depends on day-count, domicile, and personal ties, each of which can be acquired or lost over time.
- Obtaining a Tax Residence Certificate from the Mauritius Revenue Authority is what lets owners claim double taxation treaty benefits.
- Substance requirements are directly linked to residency status, and weak substance is a common compliance risk for non-resident owners.
Tax Residency in Mauritius: What Foreign Owners Need to Know
Tax residency in Mauritius determines whether your company or you personally pay tax on worldwide income or only on income with a local source. The framework sits within the Income Tax Act 1995 and is administered by the Mauritius Revenue Authority (MRA), with the Financial Services Commission (FSC) overseeing the licensing and substance side for globally focused entities. This status matters to any non-resident who incorporates a Mauritius company, holds investments through one, or spends meaningful time on the island.
The pages below explain how residency is established for both companies and people, how it is acquired, lost, and certified, and how it interacts with treaties, substance rules, and anti-avoidance measures. It will be most useful to foreign business owners and their advisers weighing a Global Business Licence (GBL) structure or planning personal relocation. The consolidated Income Tax Act published by the MRA is the primary reference throughout.
How Mauritius Defines Company Tax Residency: Incorporation and Place of Effective Management
A company is tax resident in Mauritius if it is incorporated locally or if its central management and control (CMC) sit on the island. Either test, on its own, is enough.
The reverse also holds: a company incorporated in Mauritius but managed and controlled from abroad is treated as non-resident under section 73A of the Income Tax Act. Where you direct strategy and key decisions matters as much as where you registered the entity.
The statute does not spell out how to locate CMC, and there is no local case law on the point. The MRA therefore applies international principles, drawing on De Beers Consolidated Mines Ltd v Howe [1906] AC 455, which fixed CMC at the place where a company's real business is directed.
In practice, the analysis turns on the board. If a parent or majority shareholder abroad makes all the strategic calls and the local entity merely executes, CMC lies with the parent. Where directors genuinely deliberate and decide for themselves, CMC sits where that board operates.
| Entity / situation | Residency treatment |
|---|---|
| Incorporated in Mauritius | Resident |
| CMC in Mauritius (wherever incorporated) | Resident |
| Mauritius-incorporated, CMC abroad | Non-resident (s.73A) |
| Authorised Company (former GBC2) | Non-resident; files return within 6 months of year-end |
| Trust administered locally, majority of trustees resident | Resident |
| Société with seat in Mauritius or a resident associate/gérant | Resident |
The distinction carries a direct cost. A resident corporation is taxed on worldwide income; a non-resident is liable only on Mauritius-source income, subject to any treaty.

Individual Tax Residency: Day-Count, Domicile, and Personal Ties
Three tests decide individual residency, and meeting any one makes you resident. You qualify by spending at least 183 days in Mauritius in an income year, by accumulating at least 270 days across the current and two preceding years, or by being domiciled in Mauritius unless your permanent place of abode lies elsewhere.
The income year runs from 1 July to 30 June, and both day thresholds are measured against it. Residence is assessed afresh each fiscal year, so a foreigner who exceeds 183 days one year and leaves the next is resident only for the year of presence.
For non-citizens, the domicile test rarely bites on arrival. Buying property and moving your family does not, by itself, make you resident; the MRA reserves the domicile condition for those settling more permanently, so most newcomers turn on the 183-day or 270-day count.
Once resident, you are taxed on income arising in Mauritius and on foreign income to the extent it is received in or used in Mauritius. This remittance feature is central to planning and is examined further below.
Holding an Occupation Permit or Residence Permit does not make you tax resident. For tax, physical days on the island govern, and the MRA can verify them against Passport and Immigration records.
Acquiring Mauritius Tax Residency for Companies and Individuals
For companies, the practical route to resident status is the Global Business Licence. Applications go to the FSC through a licensed management company on a prescribed form, with certified documents and the relevant fees.
To be managed and controlled from Mauritius, and so taxed as a resident, a GBL must satisfy a defined set of conditions:
- Conduct its core income-generating activities in or from Mauritius
- Be administered by a licensed management company
- Appoint at least two Mauritius-resident directors capable of independent judgment
- Keep its principal bank account in Mauritius at all times
- Maintain accounting records at the local registered office
- Have financial statements prepared and audited in Mauritius
- Hold board meetings attended by at least two local directors
For individuals, residency follows the day-count or domicile tests already described. After becoming resident, you must obtain a Tax Account Number (TAN) to file returns, and the electronic individual return is due by 15 October each year.
A Premium Visa exists for remote workers. Income earned while living in Mauritius under that visa is not taxed locally unless certain thresholds are met, and the relief does not extend to those employed by a Mauritian employer.

Losing or Ceasing Tax Residency in Mauritius
Individual residency lapses the moment you fail all three statutory tests in a given year. Because the 270-day rule aggregates across three years, you can plan visits to stay under the threshold and remain non-resident.
The MRA's reasoning was illustrated in Tax Ruling TR289 (December 2025), where a Mauritian-born taxpayer with property and emotional ties to the island was found not resident because her permanent place of abode and the centre of her life were clearly overseas. Substance of daily circumstances, not property ownership or birth, decided the case.
A Mauritius-incorporated company can shed residency by moving its place of control and management abroad, provided it can show the MRA acceptable reasons for being run from outside. For GBL entities, the risk runs the other way: lose substance and you lose status.
Where a GBL breaches substance rules, the FSC may direct it to cease part or all of its business or take other remedial steps. Failing the residency requirements strips a Global Business Company of its status and, with it, the Partial Exemption Regime and treaty access. GBL holders must also apply to the FSC annually to renew the licence and keep demonstrating substance.
The Tax Residence Certificate (TRC) and How to Obtain One from the Mauritius Revenue Authority
A Tax Residence Certificate is the MRA's official confirmation that an individual or company is resident in Mauritius for tax purposes. A GBL that wants to claim a double taxation treaty benefit must hold one.
All applications are made online. A certificate covers a first issue, renewal, or re-issue, and a single application can request a TRC for more than one country within the same validity period.
- The management company files on the TRC e-services portal using credentials issued by the MRA.
- For GBL companies, the application is routed first to the FSC, then to the MRA.
- Provided the required income tax return has been filed, the MRA generally issues the certificate within seven days.
- Individual certificates align with the fiscal year and are collected in person at the MRA Head Office, Ehram Court, Port Louis.
The validity of a TRC cannot exceed one year. A fee applies, varying by applicant type and payment method, and once issued the certificate may be apostilled by the Prime Minister's Office for use abroad under the Hague Convention.
Applications for certification in respect of an income year are addressed to the Director-General of the MRA.

Dual Residence and Tie-Breaker Rules Under Mauritius Double Taxation Agreements
A person or company can be resident in two countries at once, because each applies its own domestic test. Treaties resolve the clash, and Mauritius has a sizeable network to draw on.
| Status | Count | Examples |
|---|---|---|
| Concluded treaties | 45 | (full list on MRA site) |
| Awaiting ratification | 7 | Kenya, Nigeria, Morocco, Russia, Angola, Gabon, Comoros |
| Awaiting signature | 7 | Czech Republic, Gibraltar, Guyana, Malawi, The Gambia, Curaçao, Botswana (new) |
| Under negotiation | 19 | Canada, Portugal, Spain, Saudi Arabia, Algeria, Tanzania |
For individuals, most Mauritius treaties follow the OECD Model's sequential tie-breaker: permanent home, then centre of vital interests, then habitual abode, then nationality, and finally a mutual agreement procedure (MAP) if all else fails. The full schedule of agreements sits on the MRA treaty page.
Company tie-breakers have shifted. The older Mauritius–South Africa agreement allocated residence to the place of effective management, so a South African company effectively run from Mauritius was treated as Mauritius-resident; the revised agreement replaced that test with a case-by-case mutual agreement decision, which introduces uncertainty for dual-resident firms.
The wider trend points the same way. The OECD has moved away from automatic place-of-management tie-breakers toward MAP resolution, and the India–Mauritius protocol signed on 7 March 2024 added a Principal Purpose Test, which had not entered into force as of that report.
Mauritius also exchanges information widely. It joined the OECD/Council of Europe Convention on Mutual Administrative Assistance in June 2015, began reporting under the Common Reporting Standard from 2018, and signed a FATCA Model 1 agreement with the United States on 27 December 2013, under which in-scope institutions report to the MRA for onward transmission to the IRS.
Substance Requirements and Their Link to Residency Status
Substance is the price of the benefits. The rules were formalised after OECD BEPS commitments and EU Code of Conduct Group standards, and the FSC enforces them through the GBL framework under the Financial Services Act 2007.
Meeting them is essential to keep the licence, qualify for the 80% partial exemption on foreign-source income, claim treaty relief, and obtain a TRC. The 80% regime replaced the former deemed foreign tax credit for GBC1 companies from 1 January 2019 and depends on the prescribed conditions being satisfied.
The minimum conditions for managed-and-controlled status are concrete:
- At least two Mauritius-resident directors of sufficient calibre
- A principal bank account kept in Mauritius at all times
- Accounting records held at the local registered office
- Statutory financial statements prepared and audited in Mauritius
Beyond the checklist, the FSC weighs the whole picture: local headcount and qualifications, the adequacy of premises, local spending, and the frequency and quality of board meetings. Quarterly meetings are common for actively managed companies, and minutes must show real deliberation rather than rubber-stamping.
Physical premises are not generally required, though the FSC may insist on them for categories of GBC seeking tax holidays. Several functions, including office space, local directors, staff, and company secretarial support, may be outsourced to a licensed management company. Separately, the MRA assesses a company's Core Income-Generating Activities before granting a TRC or confirming the exemption.
Why Tax Residency Matters for a Non-Resident Foreign Owner
The headline consequence is the tax base. A resident company is taxed on worldwide income, while a non-resident pays only on Mauritius-source income.
Treaty relief flows from the certificate. A GBL is resident and can obtain a TRC, which DTA partner authorities use as proof of residence to grant reduced withholding rates on dividends, interest, royalties, and capital gains. Mauritius operates a credit system, allowing relief for foreign tax of a similar character paid on income declared locally, and it levies no capital gains tax, which favours owners holding equity through a Mauritius entity.
Anti-avoidance rules temper these advantages. Controlled foreign company provisions can attribute a CFC's undistributed income to a resident parent where the arrangement is non-genuine and tax-driven, and the General Anti-Avoidance Rule under section 90 of the Income Tax Act targets transactions whose dominant purpose is a tax benefit, judged by form and substance.
Individuals have their own reason to care: proving Mauritius residency to a home country for tax emigration or exit procedures requires a TRC from the MRA.
For large multinational groups with consolidated revenue of at least EUR 750 million in two of four preceding years, a Qualified Domestic Minimum Top-up Tax applies from the year of assessment beginning 1 July 2025 where the group's combined effective rate in Mauritius falls below 15%.
Common Pitfalls and Compliance Risks Around Mauritius Residency
The MRA looks past the org chart. If strategic and commercial decisions are consistently taken by a parent or shareholder abroad, central management and control, and therefore residency, may be found outside Mauritius even with local directors appointed.
Losing substance compounds quickly. The FSC can revoke the licence, the MRA can refuse or decline to renew the TRC, partner countries can deny treaty benefits, the 80% exemption can fall away, and additional assessments and penalties may follow. Governance arrangements are part of the substance regulators examine, not administrative formalities.
For individuals, recent decisions have sharpened the analysis. The Dilloo line of cases, through the Assessment Review Committee in 2022 and the Supreme Court in 2024 and 2025, together with Tax Ruling TR289, exposed a structural tension in how residency and remittance interact.
A few findings deserve attention before you move money:
- Foreign income becomes taxable when received or used in Mauritius, irrespective of residency status, on the ARC's strict reading of section 5(3).
- A taxpayer who cannot evidence non-residence may be deemed resident on the basis of permanent place of abode.
- Foreign savings transferred to Mauritius keep their income character.
- Only a certificate from a foreign tax authority proves foreign tax suffered; an employer letter will not do.
Day-count discipline cuts both ways. A long-term Occupation Permit combined with most of the year spent abroad usually leaves you non-resident, while extended stays on short-term visas can accidentally cross the 183-day line, and the MRA cross-checks days against immigration records. Consider exit charges in your home country before establishing Mauritius residency, since disputes here run first to the Assessment Review Committee, then the Supreme Court, with onward appeal to the Privy Council.
Conclusion
Residency in Mauritius rests on where decisions are made and where days are spent, not on incorporation papers or permits alone. For a foreign-owned company, the benefits of resident status, treaty access, the partial exemption, and a clean certificate, depend on genuine local substance and a board that truly governs. Individuals should map the day-count and domicile tests against the remittance rule before transferring funds, since money received or used on the island can be taxed regardless of formal status. Treat the TRC, substance, and governance as a single connected obligation, and the structure holds up to scrutiny.

Frequently Asked Questions
Yes, incorporation in Mauritius alone makes a company resident, but the reverse is also possible. A locally incorporated company managed and controlled from abroad is treated as non-resident under section 73A, so where your board actually decides matters.
You become resident by spending at least 183 days in a single income year, or at least 270 days in aggregate across the current and two preceding years. The income year runs from 1 July to 30 June, and residence is reassessed each fiscal year.
No. Immigration and tax law are separate, so holding an Occupation Permit or Residence Permit confers no tax residency by itself. What counts is the number of physical days spent on the island, which the MRA can verify against immigration records.
The MRA generally issues a TRC within seven days of application, provided the required income tax return has been filed. Its validity cannot exceed one year, and individual certificates are aligned to the fiscal year.
The consequences are serious and overlapping. The FSC may revoke the licence or direct the company to cease business, the MRA may refuse or decline to renew the TRC, treaty benefits and the 80% partial exemption can be lost, and additional assessments and penalties may follow.
It can. Following the Dilloo decisions, the strict reading of section 5(3) means foreign income is taxable when received or used in Mauritius regardless of residency status. Plan remittances carefully, since spending or banking funds locally can trigger an unexpected liability.
