Mauritius CIS Fund: The Africa and India Investment Gateway

Mauritius as a Fund Domicile: Strategic Positioning

Mauritius has established itself as a specialist fund jurisdiction serving two primary investment corridors: India and Sub-Saharan Africa. The island nation's appeal is rooted in its extensive double taxation treaty network (over 45 treaties), its membership of the Common Market for Eastern and Southern Africa (COMESA), its English-speaking legal system based on a hybrid of French civil law and English common law, and its time zone advantage (GMT+4) bridging European and Asian business hours.

The Mauritius Financial Services Commission (FSC) regulates collective investment schemes under the Securities Act 2005 and the Securities (Collective Investment Schemes and Closed-end Funds) Regulations 2008. The jurisdiction offers a range of fund vehicles, with the Global Business Company (GBC) structured as a CIS being the most common for international fund managers.

Fund Categories Under the Securities Act

Mauritius offers several fund categories:

CIS Manager Licence: Any entity that manages a CIS in Mauritius must hold a CIS Manager licence from the FSC. The CIS Manager is subject to ongoing regulatory requirements including capital adequacy, compliance officers, risk management, and annual reporting.

Open-ended funds: Structured as companies, limited partnerships, or unit trusts. Investors may subscribe and redeem at NAV, subject to the fund's liquidity terms. Used for hedge fund strategies, listed equity portfolios, and multi-asset mandates.

Closed-end funds: Used for private equity, venture capital, real estate, and infrastructure strategies where the underlying assets are illiquid. Structured with a defined fund life (typically 8–12 years), capital commitments, and a drawdown mechanism.

Expert funds: Restricted to expert investors (those investing a minimum of US$100,000, or who are sophisticated investors as defined by the FSC). Expert funds benefit from lighter regulatory requirements and faster approval times.

Professional CIS: Available to sophisticated investors only, with the highest minimum subscription thresholds and the lightest regulatory oversight.

The India Corridor

The India-Mauritius Double Taxation Avoidance Convention (DTAC), signed in 1983 and amended by protocol in 2016, historically provided a zero-rate capital gains tax on the disposal of Indian securities by Mauritius-resident entities. This made Mauritius the preferred domicile for foreign portfolio investors (FPIs) and private equity funds investing in India.

The 2016 protocol introduced source-based taxation of capital gains on shares acquired after 1 April 2017, effectively eliminating the capital gains tax exemption for new investments. Under the amended treaty:

• Capital gains on shares acquired before 1 April 2017 remain exempt from Indian capital gains tax
• Capital gains on shares acquired on or after 1 April 2017 are subject to Indian capital gains tax at the rates applicable under Indian domestic law
• Interest income is subject to a reduced withholding rate of 7.5% under the treaty (compared to 20%–40% under Indian domestic law)
• Dividend income is subject to a reduced withholding rate under the treaty

Despite the erosion of the capital gains exemption, Mauritius remains relevant for India-focused funds due to:

• Reduced withholding rates on interest and dividends
• Familiarity of Indian regulators and market participants with Mauritius-domiciled entities
• The established infrastructure of Mauritius-based fund administrators, custodians, and legal counsel with India expertise
• The ability to combine India investments with other emerging market allocations (Africa, Southeast Asia) within a single Mauritius vehicle

The Africa Corridor

Mauritius is a member of COMESA, the Southern African Development Community (SADC), and the African Continental Free Trade Area (AfCFTA). These memberships, combined with bilateral investment treaties (BITs) with numerous African states, position Mauritius as the preferred holding and fund domicile for investments into Sub-Saharan Africa.

Key advantages for Africa-focused funds include:

• Investment protection: Mauritius has BITs with over 25 African countries, providing protections against expropriation, fair and equitable treatment standards, and access to international arbitration (typically ICSID)
• COMESA investment treaty: The COMESA Investment Agreement provides additional protections for investments within the COMESA common market
• Tax treaty benefits: Mauritius has DTAs with several African countries (South Africa, Kenya, Uganda, Rwanda, Mozambique, Senegal, and others) that provide reduced withholding tax rates on dividends, interest, and royalties
• Regulatory familiarity: African regulators, banks, and counterparties are accustomed to dealing with Mauritius-domiciled entities. In many cases, local regulations specifically contemplate investment from Mauritius-based structures
• Currency convertibility: Mauritius imposes no exchange controls, and the Mauritian rupee is freely convertible. This is particularly important when investing in African countries with restricted currencies

Substance Requirements

The Mauritius FSC and the OECD's Base Erosion and Profit Shifting (BEPS) initiative have driven a significant increase in the substance requirements for Mauritius GBCs:

Under the Finance Act 2018 and subsequent FSC guidance:

• Physical presence: The GBC must have its place of effective management in Mauritius, including holding board meetings in Mauritius and ensuring that key decisions are made in Mauritius
• Local directors: A majority of directors must be resident in Mauritius (or the board as a whole must demonstrate effective management from Mauritius)
• Qualified employees: The GBC must employ a sufficient number of qualified persons in Mauritius to conduct its core income-generating activities
• Office space: The GBC must maintain a registered office and physical operating premises in Mauritius
• Expenditure: The GBC must incur a minimum level of expenditure in Mauritius proportionate to its activities
• Bank account: The GBC must maintain a bank account in Mauritius

For a CIS fund, these substance requirements apply primarily at the CIS Manager level rather than the fund level. The CIS Manager must demonstrate that investment decisions are made in Mauritius, that risk management functions are performed locally, and that the manager has sufficient local staff and infrastructure.

Tax Regime

Mauritius GBCs are subject to corporate income tax at 15%, but benefit from:

• Foreign tax credit: An 80% deemed foreign tax credit, resulting in an effective tax rate of 3% on foreign-source income. This credit is available automatically and does not require proof of actual foreign tax paid
• Partial exemption system: Under the partial exemption regime introduced in 2019, certain categories of income (including income from CIS, foreign dividends, and interest) qualify for an 80% exemption, resulting in the same 3% effective rate
• No capital gains tax: Mauritius does not impose capital gains tax on the disposal of securities
• No withholding tax: No withholding tax on dividends, interest, or royalties paid by a Mauritius entity to non-residents
• No exchange controls: Full freedom to repatriate capital and income

Costs and Timelines

• Fund structuring (legal): US$40,000–US$100,000 depending on complexity
• FSC CIS licence application: Processing time of 4–8 weeks; application fee approximately US$2,000–US$5,000
• CIS Manager licence: Processing time of 8–12 weeks; annual fee approximately US$3,000–US$5,000
• GBC application: Processing time of 2–4 weeks; annual fee approximately US$2,000
• Fund administration: US$30,000–US$80,000 per annum depending on AUM and complexity
• Local substance costs: US$30,000–US$80,000 per annum for local directors, office space, and qualified employees
• Audit: US$10,000–US$25,000 per annum

Total first-year costs for a Mauritius CIS fund are typically US$150,000–US$350,000, with ongoing annual costs of US$100,000–US$250,000.

When to Choose Mauritius

Mauritius is the optimal domicile when:

• The fund invests primarily in India and benefits from the treaty-reduced withholding rates on interest and dividends
• The fund invests in Sub-Saharan Africa and requires BIT protection and tax treaty access
• The manager wants a jurisdiction that African regulators and counterparties recognise and accept
• The fund combines India and Africa investments in a single vehicle
• The effective tax rate of 3% on foreign-source income provides a meaningful advantage over alternative domiciles

Mauritius is less suitable when:

• The fund has no nexus to India or Africa
• The investor base is exclusively European (Luxembourg or Ireland are more appropriate)
• The fund's primary market is the US (Cayman or BVI are standard)
• The manager cannot or will not meet the substance requirements in Mauritius

Key Takeaways

• Mauritius is a specialist fund domicile serving the India and Sub-Saharan Africa investment corridors, regulated by the FSC under the Securities Act 2005
• The India-Mauritius treaty still provides reduced withholding rates on interest and dividends, though the capital gains tax exemption for new investments was eliminated by the 2016 protocol amendment
• Africa-focused funds benefit from Mauritius's COMESA membership, 25+ bilateral investment treaties, and regulatory familiarity across the continent
• Substance requirements have increased materially since 2018 — the CIS Manager must demonstrate local decision-making, qualified employees, office premises, and minimum expenditure in Mauritius
• The effective tax rate on foreign-source income is 3% through the deemed foreign tax credit or partial exemption regime, with no capital gains tax and no withholding on distributions
• Total annual operating costs for a Mauritius CIS fund, including substance, are US$100,000–US$250,000, making it cost-competitive with Caribbean alternatives for managers who benefit from the treaty network
