Key Takeaways
- Double taxation agreements allocate taxing rights between countries, helping non-resident owners avoid being taxed twice on the same income.
- Claiming treaty benefits depends on holding a valid tax residence certificate and following the correct procedure in each jurisdiction.
- Anti-abuse safeguards such as Limitation on Benefits and the Principal Purpose Test mean treaty access requires genuine substance, not just structure.
- Developments like the MLI and the India treaty renegotiation show that treaty positions can change, so reliance should be reviewed regularly.
Mauritius as a Treaty Hub: Why Its DTA Network Matters
Tax treaties in Mauritius are the legal backbone of the island's role as a routing point for cross-border investment, particularly into Africa and across the Indo-Pacific corridor. The network of double taxation agreements (DTAs) is administered by the Mauritius Revenue Authority alongside the Financial Services Commission, with the Income Tax Act 1995 and the Financial Services Act 2007 supplying the domestic framework.
For a foreign investor, the appeal is straightforward: a properly structured Mauritius entity can lower withholding taxes and avoid being taxed twice on the same income. This article explains how those treaties work, how many exist, how benefits are claimed, and how anti-abuse rules have reshaped what treaty access actually requires.
It will matter most to non-resident fund managers, holding-company owners, and their advisers weighing whether a Mauritius vehicle still earns its place in a cross-border structure.
What a Double Taxation Agreement Actually Does
A DTA allocates taxing rights between two countries so that the same income is not taxed in both. In practice, it caps withholding tax on dividends, interest, royalties, and capital gains, and it defines which state may tax a company's business profits.
Where income comes from a country with which Mauritius holds a treaty, a credit is granted for the foreign tax paid, set out in the Income Tax (Foreign Tax Credit) Regulations 1996. Certain treaty clauses go further, exempting specified foreign-source income from tax in Mauritius altogether.
The modern purpose of these agreements has shifted. Treaties are still meant to eliminate double taxation, but they are now equally designed to stop businesses from using them to drive their tax bill to near zero.

The Scope and Size of Mauritius's DTA Network
Mauritius has signed DTAs with 46 countries, with over 45 in force. The reach extends across major capital-exporting and capital-importing economies, which is what makes the island a conduit for investment flows into Africa and Asia.
The pipeline beyond the in-force agreements is active, and a foreign owner planning a multi-year structure should know which partners are settled and which remain provisional.
| Status | Count | Examples |
|---|---|---|
| Awaiting ratification | 7 | Angola, Comoros, Gabon, Kenya, Morocco, Nigeria, Russia |
| Awaiting signature | 7 | Botswana (new), Curacao, Czech Republic, Gibraltar, Guyana, Malawi, The Gambia |
| Under negotiation | 19 | Algeria, Canada, Greece, Iran, Portugal, Saudi Arabia, St. Kitts & Nevis |
| Protocols awaiting signature | 3 | India, Mozambique, Uganda |
| Terminated | 3 | Nepal, Senegal, Zambia |
A treaty awaiting ratification or signature confers no benefits until it enters into force. Three terminations also confirm that treaty access is not permanent, so reliance on any single agreement carries timing risk.
Key Treaty Partners and Strategic Relationships
The agreements that carry the most strategic weight are those with the United Kingdom, India, South Africa, Singapore, and France. The India treaty did the most to build the island's reputation: Mauritius accounted for roughly one-third of foreign direct investment into India over the 15 years from 2000 to 2015.
African coverage is a deliberate focus, with in-force partners including Kenya (2012), Rwanda (2013), Zimbabwe (2013), Lesotho (1997), and Mozambique (2012). For investors building holding structures into the continent, this is the practical core of the network.
The United States is a different case. On 27 December 2013 the two countries signed a Tax Information Exchange Agreement and a Model 1 FATCA intergovernmental agreement, so information exchange is formalised even though there is no full DTA.
Mauritius joined the OECD Inclusive Framework on BEPS in 2017 and participates in the Common Reporting Standard from 2018. A foreign owner should treat account-level transparency to home-country authorities as a given.

How Treaties Define Permanent Establishment and Tie-Breaker Rules
A permanent establishment (PE) is generally a fixed place of business through which a foreign enterprise operates, such as a branch, office, factory, or a dependent agent who routinely concludes contracts on its behalf. Where a PE exists in the other state, that state may tax the profits attributable to it.
The India treaty extends this through a service PE rule. Following the 2016 Protocol, furnishing services (including consultancy) through personnel creates a PE where the activities run for more than 90 days within any 12-month period on the same or a connected project.
Dual residence is resolved by tie-breaker clauses. For companies under the India treaty, the entity is treated as resident where its place of effective management sits; central management and control rests in Mauritius only where day-to-day management and affairs are genuinely carried out there, the test from De Beers Consolidated Mines Ltd v Howe (1906).
For individuals, the residence rules in the Income Tax Act 1995 apply first, after which the relevant treaty clause governs any conflict. Where a treaty has been modified by the Multilateral Instrument, the effective-management test is frequently replaced by a Mutual Agreement Procedure, under which both tax authorities decide residence jointly.
Claiming Treaty Benefits: Tax Residence Certificates and Procedure
Treaty access runs through a single vehicle. A Global Business Company (GBC), incorporated under the Companies Act 2001 and licensed by the FSC, is a Mauritius tax resident and is the entity foreign investors use to reach the DTA network.
The Authorised Company is the opposite case: treated as non-resident and taxed only on Mauritius-source income, it cannot claim treaty benefits at all. Choosing the wrong structure forfeits the entire reason for being in Mauritius.
To claim benefits, a GBC obtains a Tax Residence Certificate (TRC) from the Director General of the Revenue Authority, which then evidences treaty entitlement to the foreign tax authority. The steps are sequential:
- The FSC must first recommend the application before the Revenue Authority will process it.
- The company submits its TRC application together with the tax return required under the Income Tax Act 1995.
- The certificate is generally issued within seven days of application.
- The Revenue Authority reviews substance at issue, and the TRC is granted annually rather than once.
A valid TRC is prima facie evidence of treaty entitlement and benefits cannot be denied without clear evidence of abuse. For the India treaty, however, a TRC by itself no longer secures benefits; genuine substance must also be shown.

Anti-Abuse Safeguards: Limitation on Benefits and the Principal Purpose Test
The most operationally significant safeguard in most Mauritius treaties is the beneficial ownership test. The Revenue Authority expects a company claiming protection to show genuine central management and control, not mere registration.
Layered on top is the Principal Purpose Test (PPT), which denies benefits where obtaining a tax advantage was one of the main purposes of a transaction or structure. For treaties modified by the Multilateral Instrument, the PPT enters automatically.
The India treaty carries its own limitation-on-benefits rule. A Mauritius resident is deemed a shell company, and denied benefits, where its operating expenditure in Mauritius falls below INR 2,700,000 (about USD 40,500) in the preceding 12 months. The protocol signed on 7 March 2024 then made the PPT explicit for that treaty.
Substance is policed by the FSC through the GBC licensing framework, formalised after OECD BEPS commitments and EU Code of Conduct standards. The cost of failure is steep.
- Failing the substance test can trigger licence revocation by the FSC, refusal of a TRC, denial of treaty benefits by partner countries, loss of the partial exemption, and back-tax assessments with penalties.
The Multilateral Instrument (MLI) and Its Impact on Mauritius Treaties
Mauritius deposited its instrument of ratification on 18 October 2019, and the MLI entered into force for the island on 1 February 2020. It is a confirmed party in the OECD's official record of signatories and parties.
The MLI only modifies treaties that both partners designate as Covered Tax Agreements. Mauritius has filed those notifications, but coverage is far from universal.
A notable carve-out is India: Mauritius deliberately did not list that treaty as a Covered Tax Agreement, so MLI changes never touched it. Those reforms came instead through the bilateral protocols of 2016 and 2024.
Other treaties left unmodified by the MLI include those with Australia, Bangladesh, Germany, Ghana, Jersey, Madagascar, and Mozambique. Several partners, among them Italy, Kuwait, Namibia, and Eswatini, have not yet deposited their MLI ratification, so the date their treaties change is not yet known.
The key provisions Mauritius adopted are the PPT (BEPS Action 6) and enhanced PE rules (BEPS Action 7), with mandatory binding arbitration opted into for some treaties. To see how a specific agreement reads after MLI changes, the Revenue Authority publishes synthesised texts, though a synthesised version for Sweden remains in preparation.
The India Treaty Renegotiation and Lessons for Treaty Reliance
The India treaty entered into force on 6 December 1983 to encourage mutual trade and investment. Its original Article 13(4) taxed share-alienation gains only in the resident state, and because Mauritius levies no capital gains tax, investment flowed through the island free of such tax with no anti-abuse rule to check it.
That gap closed with the 2016 Protocol, signed on 10 May 2016 and in force from 19 July 2016. India gained the right to tax capital gains on shares in Indian companies acquired on or after 1 April 2017.
The change was prospective, which matters for any existing structure:
- Investments made up to 1 April 2017 were grandfathered and remain fully protected.
- Gains realised between 1 April 2017 and 31 March 2019 were taxed at 50% of the applicable Indian rate.
- The protocol set a 7.5% withholding cap on interest and added Article 12A capping technical-service fees at 10% where the beneficial owner is a Mauritius resident.
The 2024 Protocol then layered on BEPS Action 6 anti-abuse measures, including a revised preamble and the PPT. Judicial support for genuine structures has held: in Tiger Global International III Holdings (Delhi High Court, 2024), treaty benefits for a private equity fund were upheld against the Authority for Advance Rulings.
The wider lesson is that any treaty granting generous benefits is a candidate for renegotiation as source countries move to reclaim taxing rights. A structure that depends on a single favourable clause carries built-in policy risk.
Practical Considerations for Non-Resident Owners and Advisers
Treaty access in Mauritius now turns on substance, not paperwork. The GBC is the only DTA-eligible vehicle, must at all times be administered by an FSC-licensed Management Company, and is taxed at 15% with a partial exemption of 80% to 95% available on qualifying income where substance is met.
The FSC assesses substance in the round: local employees and their qualifications, physical premises, local expenditure, the frequency and reality of board meetings held on the island, and whether the core income-generating activities genuinely occur there.
| Requirement | What it means in practice |
|---|---|
| Personnel | At least one suitably qualified person, full-time and on-site |
| Premises | A physical office or registered premises maintained at all times |
| Banking | Principal bank account with a Mauritius-licensed bank (e.g. MCB, SBM, MauBank, AfrAsia) |
| Governance | Board meetings genuinely held and decisions taken in Mauritius |
| TRC | Required to claim treaty benefits, reviewed annually |
For India-linked structures, capital gains on shares acquired before April 2017 stay fully protected, while later acquisitions still benefit from reduced dividend and interest withholding. Across every treaty, a foreign owner must now be ready to show that the primary reason for the Mauritius entity was not the tax benefit itself.
The combined effect of the PPT, substance rules, Pillar Two, and automatic information exchange is a single demand: real economic presence with documented decision-making. The island has not become less useful, but its usefulness depends on operating with genuine rigour.
Conclusion
Treaty benefits in Mauritius remain real and valuable, but they are no longer automatic. A Global Business Company with genuine substance, an annual Tax Residence Certificate, and decisions made on the ground can still access reduced withholding rates and avoid double taxation across a wide network. The India renegotiation is the clearest signal of where policy is heading, so any structure should be built to survive a Principal Purpose Test and the eventual revisiting of generous clauses. Treat the island as a place to conduct real business, not a stamp on a transaction, and the network continues to work in your favour.

Frequently Asked Questions
Mauritius has signed DTAs with 46 countries, with over 45 in force, including the United Kingdom, India, South Africa, Singapore, and France. A further seven await ratification, seven await signature, and 19 are under negotiation, so the network continues to expand.
No. An Authorised Company is treated as a non-resident and taxed only on Mauritius-source income, which means it cannot claim treaty benefits. Only a Global Business Company, which is a Mauritius tax resident, can access the DTA network.
A TRC is generally issued within seven days of application, provided the company has filed the return required under the Income Tax Act 1995. The FSC must first recommend the application before the Revenue Authority will process it, and the certificate is granted annually rather than once.
For most treaties a valid TRC is prima facie evidence of entitlement, and benefits cannot be denied without clear evidence of abuse. For the India treaty, however, a TRC alone is no longer sufficient; genuine substance must also be demonstrated, and the Principal Purpose Test applies following the protocol signed on 7 March 2024.
The 2016 Protocol gave India the right to tax capital gains on shares in Indian companies acquired on or after 1 April 2017, closing the original capital gains exemption. Earlier acquisitions remain grandfathered and fully protected, while later ones still benefit from reduced dividend and interest withholding rates, so the treaty stays relevant for fund and holding structures.
The FSC expects at least one suitably qualified full-time person on-site, physical premises, adequate local expenditure, board meetings genuinely held in Mauritius, and a principal bank account with a Mauritius-licensed bank. Failing these tests can cost the GBC licence, the TRC, the partial exemption, and treaty benefits, alongside back-tax assessments and penalties.
