For over twenty years, Mauritius has established itself as a go-to destination for structuring investment flows into the African continent. Long seen as a mere fiscal “conduit,” the jurisdiction has embarked on a deep transformation: shifting from a model centered on tax optimization to a role as a platform for substance, governance, and infrastructure serving Africa’s financing. At the heart of this shift, the Global Business Company (GBC) regime—with its 15% tax rate and, for certain income, an effective rate that can drop to 3%—remains the primary tool for this “Africa gateway” ambition.
From an Offshore Center to a Substance-Based African Platform
The official strategy of the Mauritian government is clear: consolidate the country as the preferred gateway to Africa, but on fundamentally different foundations than in the past. The international financial services zone no longer presents itself as a mere offshore center fueled by a few tax agreements, but as a modern International Financial Centre (IFC), aligned with OECD, FATF, and European standards.
Historically, Mauritius served as an investment platform into Africa due to the infrastructure and legal gaps in local markets. Its appeal rested on a predictable legal framework (hybrid Franco-British law), a final judicial recourse to the London Privy Council, and a network of tax treaties that reassured investors. This reality fully justified its function as a “gateway.”
But the continental landscape has changed. Several African stock exchanges have modernized their systems, partnerships between regional financial centers are multiplying, and major investors are now more comfortable investing directly in certain markets. The risk, however, is not the disappearance of Mauritius, but rather the obsolescence of a purely “transit” model. The Mauritian response is to position itself as a “platform jurisdiction,” capable not only of channeling capital but, above all, of providing the structures, governance, transparency, and technology that are still lacking in many local markets.
In the new model, the Global Business Company (GBC) evolves from a simple pass-through vehicle into a genuine operational center. It now hosts real and substantive functions, such as decision-making, structuring, risk management, treasury, compliance, and, at times, dedicated investment teams.
The Weight of the Financial Sector in the Mauritian Economy
This transformation is not a technical detail: the financial sector is one of the pillars of the Mauritian economy. The latest figures illustrate its systemic dimension.
Macroeconomic Weight of the Financial Sector
| Indicator (2024–2025) | Estimated Value |
|---|---|
| Share of financial services in GDP | ~13.4% |
| Value added (direct + indirect) | ~24.8% of GDP |
| Weight of the Global Business segment (GBL/GBC) | ~8.2% of GDP |
| Share of GBL segment in corporate tax | ~68.2% of revenue |
| Direct financial sector jobs | ~19,745 people |
| Total jobs (direct + indirect) | >36,800 people |
| Sector value target by 2030 | From approx. $1.7 to $2.5 billion |
To these figures add the concrete role of Mauritius in financing the continent. According to a Capital Economics report, about 9% of foreign direct investment directed to Africa passes through Mauritian structures. These flows are estimated to have contributed to the creation of about 4.2 million jobs and more than $6 billion in annual tax revenue for African states.
Investment Flows via Mauritius into Africa
| Key Indicator | Estimate / Observations |
|---|---|
| Stock of investments structured for Africa | > $80 billion (since 2010) |
| Structured outstanding at a reference date | ~$40 billion directed to Africa |
| Number of funds domiciled in Mauritius | ~900 to 1,000 funds |
| Number of private equity funds targeting Africa | >450 funds |
| Share of Mauritius in FDI to Africa | ~9% of the continental total |
| Job creation linked to flows via Mauritius | ~4.2 million jobs |
| Annual tax revenue generated in Africa | ~$6 billion |
Beyond Africa, Mauritius also played a historical role in flows to India, even though the renegotiation of the Double Taxation Avoidance Agreement with that country marked a turning point and pushed the jurisdiction away from a heavily “India-centric” model.
The GBC Regime: A 15% Tax Framework Designed for International Use
The core of the system remains the Global Business Company, a Mauritian law structure created under the Companies Act 2001 and licensed by the Financial Services Commission (FSC). It is designed to carry on business mainly outside Mauritius, with non-residents, often in foreign currency.
A 15% Tax Rate with a Reduced Effective Rate
The standard corporate income tax rate is 15%. But a major feature of the GBC regime is the possibility of benefiting from a partial 80% exemption on certain categories of foreign-source income, subject to strict substance requirements. The effect is to bring the effective rate down to approximately 3% for that income.
For export activities of goods, a 3% rate may apply on the portion of income attributable to exports.
Alongside this, several characteristics enhance the appeal:
Key benefits in terms of taxation and capital movements
Complete absence of tax on realized capital gains.
No withholding tax on dividends paid to shareholders, whether residents or non-residents.
No withholding tax on interest and royalties paid to non-residents for foreign-source income.
Complete freedom of capital movement, with no exchange controls.
Overview: GBC, AC, and Domestic Companies
To understand the place of the GBC in the Mauritian ecosystem, it must be compared to other company forms.
| Key Features | Global Business Company (GBC) | Authorised Company (AC) | Domestic Company |
|---|---|---|---|
| Tax residency | Resident in Mauritius | Non-resident | Resident in Mauritius |
| Nominal tax rate | 15% (partial exemption possible) | 0% (but taxed in other countries) | 15% (effective rate often >15–17%) |
| Access to tax treaties (DTAs) | Yes (with TRC and substance) | No | Yes (where applicable) |
| Capital gains tax in Mauritius | None | None | None |
| Withholding tax on outgoing dividends | None | None | None |
| Substance requirements | High (directors, expenses, offices) | Minimal | Variable (often more limited) |
| Audit requirement | Yes | Not mandatory | Yes above certain thresholds |
| Ownership of property in Mauritius | Allowed | Prohibited | Allowed |
| Bank account in Mauritian rupees | Allowed | Prohibited | Allowed |
| Local activities | Prohibited (except ancillary activities) | Prohibited | Primary target |
The Authorised Company thus offers lower cost and complexity, but does not allow claiming Mauritian tax residency nor accessing the treaty network. The GBC, on the other hand, fully assumes a 15% tax resident status, with privileged access to a network heavily focused on Africa and Asia.
Substance Requirements: The End of “Shell Companies”
One of the most structuring changes in recent years is the increase in economic substance requirements. Gone are the simple letterbox companies: to benefit from GBC status, claim Mauritian tax residency, and apply the 80% partial exemption, the company must demonstrate a real presence.
Management and Control in Mauritius
The GBC must be managed and controlled from Mauritius. Concretely, this means:
– At least two resident Mauritian directors, with relevant expertise and independent judgment.
– Board meetings held in Mauritius (at least two per year), chaired locally.
– A main bank account opened with a Mauritian bank.
– Strategic decisions effectively taken on the territory.
Income-Generating Activities and Local Expenses
The income-generating activities – the Core Income Generating Activities (CIGA) – must be carried out in or from Mauritius. The regulator examines, for example, the nature and location of investment decision-making, risk management, transaction structuring, and operational management.
Indicative annual expenditure threshold in Mauritian rupees to benefit from the status, equivalent to just over $30,000.
Governance, Compliance, and Audit
The GBC is subject to dual supervision: by the FSC for licensing and financial compliance, and by the Mauritius Revenue Authority (MRA) for tax matters. Obligations include:
To stay compliant, a Mauritian company must keep its accounts and records at the registered office, prepare its financial statements in accordance with IFRS and have them audited annually by a local firm. It must file its tax return within six months of the year-end and submit an annual declaration to the Registrar of Companies. Compliance with beneficial ownership rules is imperative, involving maintaining an up-to-date register and notifying any changes to the authorities.
This regulatory density distances the image of a compliant jurisdiction. International assessments confirm this trajectory: Mauritius is “largely compliant” according to the OECD Global Forum, has been removed from the EU blacklist, and has strengthened its AML/CFT framework to incorporate all FATF recommendations.
A Treaty Network Focused on Africa and Asia
The other pillar of Mauritian attractiveness remains its network of Double Taxation Avoidance Agreements and Investment Protection Agreements. The country claims about 45 to 46 tax treaties in force, a significant portion with African and Asian states, and about 30 IPPAs providing an additional safety net through international arbitration.
Particularly Dense African Coverage
Mauritius holds one of the most extensive treaty networks in Africa, with more than twenty tax treaties in force on the continent. Partners mentioned include, among others, South Africa, Kenya, Uganda, Rwanda, Tanzania, Zimbabwe, Mozambique, Botswana, Namibia, Lesotho, Eswatini, Madagascar, Malawi, Egypt, Tunisia, Morocco, Côte d’Ivoire, Congo, Zambia, and Ghana.
These treaties aim to avoid double taxation, reduce withholding tax rates on dividends, interest, and royalties, establish mechanisms for information exchange and mutual agreement procedures, and provide legal certainty to investors.
Example of Some Treaty Withholding Tax Rates
| Partner Country (Africa) | Dividends (ranges) | Interest (max) | Royalties (max) |
|---|---|---|---|
| Botswana | 5% / 10% | 12% | 12.5% |
| Cabo Verde | 5% | 10% | 7.5% |
| Congo | 0% / 5% | 5% | Exemption |
| Egypt | 5% / 10% | 10% | 12% |
| Ghana | 7% | 7% | 8% |
| Mozambique | 8–15% | 8% | 5% |
| Namibia | 5% / 10% | 10% | 5% |
| Rwanda | 10% | 10% | 10% |
| South Africa | 5% / 10% | 10% | 5% |
| Tunisia | Exemption | 2.5% | 2.5% |
| Uganda | 10% | 10% | 10% |
| Zimbabwe | 10% / 20% | 10% | 15% |
Only GBCs with genuine substance in Mauritius and a Tax Residence Certificate can invoke these treaties. The MRA generally issues this certificate within a week for complete files, but the international context now pushes for more substantial checks on abuse situations, as illustrated by a recent Indian Supreme Court decision, which refuses to consider the TRC alone as sufficient proof in case of suspicion of a “conduit” company.
Mauritius is actively modernizing its tax treaty network. Recent or ongoing agreements include a BEPS-compliant convention with Curaçao, a new agreement with Botswana, and a signed treaty with Angola pending ratification. Amendment protocols are also under discussion with India, Uganda, and Rwanda. These actions aim to incorporate anti-abuse clauses and reassure partners, particularly African ones, of a fair sharing of the tax base.
Alignment with the 15% Global Minimum: The QDMTT and the New Tax Landscape
The subject title – “CIT 15%” – directly echoes a global movement: the implementation of the 15% effective minimum tax rate for large multinational groups under the OECD’s Pillar Two. Mauritius has chosen to align with this standard, while preserving as much as possible the attractiveness of its model.
The Qualified Domestic Minimum Top-up Tax (QDMTT)
The QDMTT is the tool through which Mauritius applies Pillar Two. It targets groups with consolidated revenue exceeding €750 million. For those groups, if the effective tax rate paid in the jurisdiction falls below 15%, a top-up tax applies to reach that threshold.
For Mauritius, the message is twofold. On one hand, it is about reassuring the international community: the country does not intend to offer ultra-low effective rates to giant conglomerates at the expense of market countries. On the other hand, the regime is calibrated for very large enterprises, leaving unchanged the comparative advantage of the classic GBC used by the majority of funds and investment vehicles, which are often below this consolidated revenue threshold.
Under Pillar Two, tax incentives that could reduce an effective rate below 15% are frozen for the entities concerned. Additionally, a Fair Share Contribution applies to large enterprises and banks, but Global Business Companies (GBCs) are explicitly excluded from this, confirming the intention to preserve the attractiveness of this segment.
Slight Increase in Tax Pressure Outside Pillar Two
In parallel, recent finance laws have slightly increased the effective rates applicable to certain regimes. For GBCs benefiting from the partial exemption, the real rate has risen from about 3% to 3.4% in a context of a climate contribution (Corporate Climate Responsibility Levy). For exporters and international trading companies, the rate has risen from 3% to about 5%. Finally, domestic companies fall roughly in a range of 17% to 19% when certain additional levies are included.
This tightening does not call the model into question but signals that Mauritius seeks a balance between tax competitiveness and budget revenue, with a view to achieving a national ambition of nominal GDP of 1,000 billion rupees by 2030.
An Increasingly Sophisticated Regulatory Environment
The evolution of the GBC cannot be understood through taxation alone. It is part of a broader overhaul of the regulatory framework, primarily driven by the Financial Services Commission and the ministry in charge of financial services.
FSC, Enforcement, and Fintech
The FSC has updated its enforcement manual, strengthening investigation procedures, settlement mechanisms, and the power to give instructions to licensed entities, including GBCs. The texts now incorporate the specifics of virtual asset regulation, via the Virtual Asset and Initial Token Offering Services Act (VAITOS), and ESG requirements, with detailed guidelines for funds.
The processing time for license applications targeted by the FSC’s e-licensing platform for certain approvals.
Digitalization and Legal Modernization
On the legislative front, Mauritius is heavily investing in digitalization: legal recognition of electronic commercial documents, strengthening the framework for electronic signatures, deploying a centralized e-KYC extended to global business, creating digital public infrastructures with a unified digital identity and secure data sharing.
Mauritius is implementing a vast five-year digital transformation plan, including a national ‘AI enablement for all’ strategy. This ambition aims to evolve the country from a tax hub to a digital hub. Concrete initiatives include the creation of a digital special economic zone, the development of connectivity and computing corridors (AI & Compute) by Mauritius Telecom, and the creation of a single ‘super app’ to centralize public services.
The GBC in Practice: Use Cases for Africa
The concrete usefulness of the GBC as an “Africa gateway” is measured in the real structurings that investors put in place.
An Ivorian cocoa processor might, for example, set up a GBC holding company in Mauritius to hold its subsidiaries in West Africa, raise debt from international lenders, structure private equity fund participations, while benefiting from no Mauritian capital gains tax on share disposals, and optimized withholding taxes on dividends and interest thanks to treaties.
A Kenyan tea exporter can use a trading Global Business Company (GBC) based in Mauritius to centralize its sales to Europe or Asia. This structure allows the export activity to benefit from the Mauritian tax regime, with a reduced tax rate on profits from international sales. At the same time, the Mauritian GBC offers access to the local international banking system and trade finance mechanisms, such as letters of credit offered by banks like MCB, AfrAsia, or Absa Mauritius.
On the fund side, a European manager can domicile a regulated fund in the European Union and use a Mauritian GBC as an investment vehicle dedicated to Africa, thus benefiting from tax treaties and the local legal infrastructure, while reassuring its subscribers through the presence of Big Four auditors and FSC supervision.
A Dense Financial Ecosystem Focused on the Continent
The success of the GBC model also relies on the ecosystem that surrounds it. There are more than 200 management companies, which play a key role in the incorporation, administration, and compliance of structures. As of end-2024, 213 such providers were operational, marking 16% growth in five years.
The Mauritian financial center is characterized by the presence of 19 banks holding more than $40 billion in assets. It also benefits from one of the highest Internet bandwidths in Africa and a modern office park, concentrated in Ébène, a tech and financial hub. This ecosystem is strengthened by the presence of major international accounting and law firms, as well as industry associations such as Mauritius Finance and the Mauritius Africa FinTech Hub.
This density of players has allowed the jurisdiction to become a preferred base for more than 450 private equity funds targeting Africa, with assets under management exceeding $130 billion.
Challenges, Criticisms, and Adaptation
Mauritius’s trajectory is not linear. The challenge to certain treaties by African countries, revelations about aggressive structuring in the past, or the episode of the FATF gray list have put the jurisdiction’s reputation under pressure. Countries like Senegal have denounced the impact of certain treaties they consider unbalanced in terms of revenue loss.
In response to criticisms, two measures have been implemented: a revision of treaties to include stricter anti-abuse mechanisms, such as limitation on benefits clauses to prevent treaty shopping, and a strengthening of substance requirements and beneficial ownership controls to demonstrate that structures are genuine decision-making centers.
Pressure does not only come from African states. Actors like Mastercard Foundation show a clear preference for structures based in African jurisdictions, which forces Mauritius to strengthen its African dimension – by multiplying partnerships, participating in regional strategies like the AfCFTA, and positioning its IFC as an element of the African value chain rather than a mere fiscal free port.
Toward a Next-Generation “Africa Gateway”
In this context, the future of Mauritius as an “Africa gateway” will depend on its ability to see through to completion its transformation into a platform of substance, technology, and governance.
This is the number of ports and capitals to which Mauritius airport is connected, illustrating the importance of logistical infrastructure for the future of the GBC.
Several budgetary and strategic initiatives clearly point in this direction: simplification of permits for foreign talent, easing of Occupation Permits in wealth management, creation of a more targeted Africa Strategy regime in the 2025–2030 financial services roadmap, reforms of the EDB to become a true “launch pad” for digital ventures aimed at Africa.
This is the annual amount, in dollars, needed to finance infrastructure on the African continent to achieve the Agenda 2063 and SDG goals.
If this transformation is carried out with sufficient speed and execution, the formula “Maurice GBC 2026: CIT 15% Africa Gateway” could well remain relevant, no longer as the slogan of a tax haven, but as the summary of a next-generation African financial center, capable of supporting the next phase of capital formation on the continent.
