Mauritius GBC Formation: Africa Gateway and Treaty Access

Mauritius has established itself as the premier gateway for investment into India and Africa. The Mauritius Global Business Company (GBC) -- formerly known as the Category 1 Global Business Licence (GBL1) -- provides access to an extensive double tax treaty network, a well-regulated financial services sector, and an effective corporate tax rate as low as 3%. However, the 2019 reforms fundamentally changed the substance requirements, and the India treaty renegotiation altered the economics for India-focused structures.

The Tax Framework

Corporate Tax

Mauritius levies corporate tax at a headline rate of 15%. However, GBCs benefit from a deemed foreign tax credit of 80% of Mauritian tax, producing an effective rate of 3% on foreign-source income.

Calculation:

• Gross foreign income: USD 1,000,000
• Mauritius corporate tax at 15%: USD 150,000
• Deemed foreign tax credit (80%): USD 120,000
• Net Mauritius tax: USD 30,000 (3% effective)

This credit is available automatically without needing to prove that foreign tax was actually paid.

Withholding Tax

Mauritius does not levy withholding tax on:

• Dividends paid by a GBC
• Interest paid by a GBC
• Royalties paid by a GBC

This makes Mauritius an efficient conduit for cross-border payments.

Capital Gains

Mauritius does not levy capital gains tax. Gains from the disposal of shares (including in foreign companies) are not subject to Mauritius tax.

The Treaty Network

Mauritius has signed DTAs with over 45 countries, with particular strength in:

India

The Mauritius-India DTA has been the primary driver of Mauritius's financial services industry. Key provisions:

• Capital gains: Following the 2017 protocol amendment (effective April 2017), India has the right to tax capital gains on Indian shares. However, investments made before 1 April 2017 are grandfathered and remain exempt from Indian CGT under the treaty.
• Dividends: 5% withholding rate for substantial holdings (25%+); 15% for portfolio holdings
• Interest: 7.5% withholding rate
• Royalties: 15% withholding rate

The 2017 amendment reduced Mauritius's advantage for new India investments, but grandfathered investments and the continuing benefits on dividends and interest maintain its relevance.

Africa

Mauritius has DTAs with over 20 African countries including:

• South Africa, Botswana, Namibia, Swaziland, Zambia, Zimbabwe
• Kenya, Uganda, Rwanda, Tanzania
• Egypt, Tunisia, Morocco
• Nigeria, Ghana, Senegal
• Mozambique, Madagascar

For investment into sub-Saharan Africa, Mauritius offers:

• Reduced withholding rates on dividends, interest, and royalties
• Capital gains allocation to the state of residence (Mauritius) under most African treaties
• A neutral, well-regulated holding platform

Asia

DTAs with China, Malaysia, Thailand, Vietnam, Bangladesh, Sri Lanka, and others provide treaty access across Asia.

The 2019 Substance Reforms

The Financial Services Act 2007 amendments, effective from January 2019, fundamentally changed the substance requirements for GBCs:

Core Income Generating Activities (CIGA)

Every GBC must conduct its core income generating activities from Mauritius. CIGA are defined based on the entity's activities:

• Holding companies: Taking strategic decisions, managing and bearing principal risk, making decisions on holding/disposing investments
• Fund management: Identifying and acquiring investment targets, making trading decisions, risk management
• IP holding: Making decisions on IP exploitation, maintaining and protecting IP
• Trading: Making strategic trading decisions, managing procurement and sales

Minimum Substance Requirements

• Adequate qualified employees in Mauritius (the number depends on the complexity of activities)
• A minimum level of annual expenditure proportionate to the company's activities (no fixed threshold, but the Financial Services Commission assesses adequacy)
• Physical presence in Mauritius (office space, not just a registered address)
• Board meetings held in Mauritius with a quorum of directors present in Mauritius

Management Company

Every GBC must appoint a licensed management company in Mauritius. The management company provides:

• Company secretarial services
• Registered office
• Administrative and accounting support
• Compliance and regulatory filings
• Director services (if needed)

Management company fees: USD 3,000-6,000+ per year, depending on the level of service.

Formation Process

1. Engage a licensed management company in Mauritius
2. Apply for a GBC licence from the Financial Services Commission (FSC)
3. Submit the application with:
   • Business plan detailing proposed activities and substance
   • KYC documentation for all shareholders, directors, and beneficial owners
   • Constitutional documents
   • Evidence of planned CIGA in Mauritius
4. FSC review and approval: Processing time 2-6 weeks
5. Incorporate the company with the Registrar of Companies
6. Establish substance: Office, employees, bank account

Total formation cost: USD 5,000-10,000 (including FSC fees, management company setup fees, and legal costs)

Annual Compliance

Cost Component	Annual Cost (USD)
FSC annual fee	1,800
Management company	3,000-6,000
Statutory audit (mandatory)	2,000-5,000
Tax return preparation	500-1,500
Local substance (employees, office)	5,000-15,000
Directors (if nominee)	2,000-5,000
Total	14,300-34,500

The annual cost of maintaining a Mauritius GBC has increased substantially since the 2019 reforms due to local substance requirements.

Banking

Mauritius has a well-developed banking sector with both local and international banks:

• SBM (State Bank of Mauritius): The largest local bank, serving GBCs and international clients
• AfrAsia Bank: International private banking and corporate banking
• MauBank: Government-owned, serving a range of corporate clients
• Standard Chartered Mauritius: International corporate banking

Account opening requires standard KYC documentation plus the GBC licence. Processing time: 2-4 weeks.

When Mauritius Works

• India investments: For grandfathered pre-2017 investments, and for ongoing dividend and interest flows
• Africa investments: Treaty access to 20+ African countries with reduced withholding rates
• Fund structures: Mauritius is a well-established jurisdiction for investment funds targeting India and Africa
• Holding structures: For groups with India, Africa, and Asia operations

When Mauritius Does Not Work

• Pure holding with no substance: Post-2019, a paper company in Mauritius will not satisfy FSC requirements
• Budget-constrained structures: Annual costs of USD 14,000-35,000 are significantly higher than BVI, Seychelles, or Panama
• India capital gains (post-2017): New investments no longer benefit from the capital gains exemption under the treaty

Key Takeaways

• Mauritius GBCs offer an effective corporate tax rate of approximately 3% through the deemed foreign tax credit mechanism.
• The treaty network of 45+ countries provides reduced withholding on dividends, interest, and royalties across India, Africa, and Asia.
• Post-2019 substance reforms require genuine CIGA conducted from Mauritius, including qualified employees, office space, and board meetings.
• Annual maintenance costs have risen to USD 14,000-35,000, reflecting substance requirements.
• The Mauritius-India DTA was amended in 2017 to allow India to tax capital gains on new investments, reducing Mauritius's advantage for new India-focused structures.
• A licensed management company is mandatory for all GBCs, providing company secretarial, administrative, and compliance services.
• Mauritius remains the premier gateway for Africa-focused investment structures and for grandfathered India investments.
