Mauritius has carved out a distinctive niche in international corporate structuring — a small island state in the Indian Ocean that became, over decades, one of the most-used jurisdictions for India-bound investment, African investment flows, and certain Asian-region holding structures. The combination of a robust treaty network (especially the historic Mauritius-India treaty), English-French bilingual legal infrastructure, OECD-compliant transparency, and 3-15% effective corporate tax rates made Mauritius a fixture in cross-border structuring throughout the 2000s and 2010s.
The picture in 2026 is more nuanced. The 2016 amendments to the India-Mauritius treaty introduced source-based taxation on capital gains for new investments, materially reducing the historic tax advantage on India-bound funds. The shift from GBC1 / GBC2 to the modern Global Business Corporation (GBC) and Authorised Company regimes, the introduction of substance requirements under economic substance rules, and EU/OECD-level scrutiny have all reshaped what Mauritius is and what it can deliver. For genuine African-focused investment and certain India-related transactions with grandfathering or specific facts, Mauritius remains useful — but for many use cases that previously chose Mauritius by default, alternatives now serve better.
This guide walks through Mauritius company formation in 2026 — the GBC vs Authorised Company distinction, substance requirements, India treaty positioning, banking access, real cost picture, and the use cases where Mauritius is still the right choice vs alternatives.
This is general educational content. Mauritius tax and corporate law continues to evolve, particularly around international substance and treaty positioning. Consult qualified Mauritius counsel and specialist international tax advisors before relying on specific structures.
Key Highlights
- Two main corporate forms: Global Business Corporation (GBC) and Authorised Company — each with distinct tax treatment, substance requirements, and use cases.
- GBC corporate tax: 15% headline rate with Partial Exemption Regime (PER) potentially reducing to effective 3% on qualifying foreign-source income — subject to substantial substance.
- Authorised Company: Tax-resident outside Mauritius (the company is incorporated in Mauritius but is non-Mauritius-tax-resident for treaty purposes); 0% Mauritius tax but cannot access Mauritius treaty network.
- Mauritius-India treaty: Substantially amended in 2016 — source-based capital gains taxation now applies to new investments. Pre-2017 investments retain grandfathered treatment.
- Substance requirements: Real Mauritius substance (employees, expenditure, office) required for GBC to access PER; substance proportionate to activities.
- Banking: Mauritius banking is accessible but selective; State Bank of Mauritius, Bank One, AfrAsia Bank, MCB are common partners — substance and clear use case matter.
- Annual cost (GBC): Typical USD 8,000-25,000 covering company secretary, registered office, accounting, audit, statutory filings.
- Best for: African investment, certain India-related structures with grandfathered facts, sub-Saharan operating businesses, certain fund structures.
Why Mauritius Matters (and the 2016 Reset)
Mauritius’s historical positioning rested on three pillars:
- India treaty: Mauritius-resident companies investing in India benefited from a treaty that taxed capital gains only in Mauritius (which had 0% effective tax on certain gains). This made Mauritius the dominant route for foreign portfolio investment and FDI into India for nearly two decades.
- Africa treaty network: Mauritius has 40+ tax treaties, including a meaningful network across Sub-Saharan Africa — making it a useful holding hub for African investment.
- Low effective tax: The GBC1 regime delivered effective rates as low as 3% through foreign tax credits, supplemented by underlying substance lighter than alternatives.
The 2016 amendments to the India-Mauritius treaty (effective April 2017) introduced source-based taxation on capital gains for new investments — meaning India can tax capital gains on Indian shares acquired post-April 2017 even if the seller is Mauritius-resident. Existing investments at the cutoff received transitional grandfathering.
The corporate regime restructuring (effective January 2019) replaced GBC1 (Global Business Licence 1) and GBC2 (Global Business Licence 2) with the modern GBC and Authorised Company forms — and introduced explicit substance requirements aligned with OECD/EU expectations.
The net effect: Mauritius is no longer the default choice for India-bound investment but remains useful for specific structures, African operations, and certain global business arrangements with appropriate substance.
GBC vs Authorised Company: The Core Distinction
Global Business Corporation (GBC)
The GBC is the primary Mauritius international company form. Key features:
- Tax resident in Mauritius — qualifies as Mauritius resident for treaty purposes (subject to substance)
- Headline corporate tax: 15% on global income
- Partial Exemption Regime (PER): 80% exemption on certain qualifying foreign-source income (dividends, interest, royalties from foreign sources under specific conditions) — effective rate ~3% on qualifying income
- Substance requirements: Two qualifying directors resident in Mauritius, principal bank account in Mauritius, accounting records kept in Mauritius, annual audit in Mauritius, board meetings in Mauritius, financial statements prepared in Mauritius, core income generating activities in Mauritius proportionate to revenue
- Licensed by FSC (Financial Services Commission) — Global Business Licence required
- Treaty access: Eligible for Mauritius’s treaty network with proper substance
Authorised Company
The Authorised Company is a different model — Mauritius-incorporated but tax-resident outside Mauritius:
- Tax resident OUTSIDE Mauritius — central management and control must be outside Mauritius
- Mauritius corporate tax: 0% (not Mauritius tax resident)
- No treaty access: Cannot use Mauritius’s treaty network
- Substance requirements: Lighter than GBC — no requirement for Mauritius-resident directors, but board meetings must NOT be in Mauritius (management is elsewhere)
- Licensed by FSC as Authorised Company
- Compliance: Annual filings with FSC; accounting records to be maintained
The Authorised Company is analogous to BVI BC or Cayman exempt company — a 0% tax jurisdiction vehicle without local treaty access. The GBC is the vehicle that uses Mauritius’s treaty network.
Substance Requirements for GBC (In Detail)
To qualify for Mauritius tax residence (and thus the treaty network and PER), a GBC must satisfy each of the following:
Director requirements
- At least two directors
- Both directors must be Mauritius-resident
- Both directors must have sufficient expertise to carry out their duties
Operational requirements
- Principal bank account in Mauritius (must be the GBC’s main operating bank account)
- Accounting records kept in Mauritius
- Statutory financial statements prepared in Mauritius
- Annual audit conducted by Mauritius-licensed auditor
- Board meetings held in Mauritius (with at least quorum present)
- Disputes resolution (where chosen) in Mauritius
Core Income Generating Activities (CIGAs)
The GBC must conduct CIGAs in Mauritius proportionate to its income — typically:
- Employment of qualified persons in Mauritius (often outsourced through service providers)
- Annual expenditure in Mauritius proportionate to the level of activities
- For specific licensed activities (financial services, fund management, IP-licensing), additional CIGAs as specified in regulations
What this means practically
The substance bar for Mauritius GBC has increased meaningfully since 2019. Pure “letterbox” GBCs are no longer viable — real Mauritius substance is required. Most modern GBCs achieve substance through:
- Engaging a Mauritius management company that provides Mauritius-resident directors, accounting, and administrative substance
- Real Mauritius office space (often within the management company)
- Mauritius-based annual audit and corporate secretariat
- Documented Mauritius board meetings with substantive decisions made in Mauritius
The annual cost of providing this substance through a quality management company runs typically USD 10,000-25,000 — meaningful for smaller GBCs.
Partial Exemption Regime (PER)
The 80% exemption applies to specific categories of foreign-source income for GBCs meeting substance requirements:
- Foreign-source dividends (with conditions)
- Foreign-source interest (with conditions)
- Foreign-source profits attributable to permanent establishments outside Mauritius
- Income from ship operations
- Foreign-source royalties (specific scenarios)
- Other qualifying foreign-source income types as specified
For qualifying income, effective tax: 15% × (1 – 0.80) = 3%.
For non-qualifying income (most Mauritius-source income, certain other types): 15% headline rate.
The 80% exemption requires demonstration that the entity has the appropriate substance proportionate to the qualifying activities — substance is a gating condition, not automatic.
Recent tax overlays for larger GBCs
The flat “15% headline / 3% effective” picture is slightly more layered for mid-size and very large GBCs since 2024-2025:
- Corporate Climate Responsibility (CCR) Levy: Since the year of assessment commencing 1 July 2024, a 2% levy on chargeable income applies to companies (now explicitly including GBCs) with turnover of at least MUR 50 million. GBCs benefiting from the Partial Exemption Regime can claim an 80% reduction on the levy, so a PER-qualifying GBC’s incremental burden is small (roughly 0.4% of chargeable income), but it does apply on top of the headline rate for larger entities.
- Qualified Domestic Minimum Top-Up Tax (QDMTT): Effective for the year of assessment commencing 1 July 2025, Mauritius imposes a 15% minimum effective rate on in-scope multinational groups with at least EUR 750 million in consolidated revenue. For such large groups, the QDMTT can override the ~3% PER outcome and bring the effective rate up to 15%.
The India Treaty Position in 2026
The Mauritius-India treaty (DTAA) has historically been Mauritius’s most-used treaty. The 2016 protocol changed the picture:
Pre-April 2017 investments (grandfathered)
- Capital gains on Indian shares acquired before April 2017 by Mauritius-resident company: Mauritius-only taxation (effectively 0%)
- Subject to limitation of benefits (LoB) clause from the original treaty
Post-April 2017 investments
- Capital gains on Indian shares acquired after April 2017: source-based (taxable in India) at applicable rates (10-40% depending on shareholding, term, etc.)
- Mauritius residence no longer provides capital gains exemption for new investments
Other treaty benefits
Other aspects of the India-Mauritius DTAA (dividends, interest, royalties, FTS) continue with the rates specified in the treaty. The capital gains amendment is the most material change.
Practical implications
- Pre-2017 investments held in Mauritius GBCs continue to benefit from the original treaty (with LoB compliance)
- New India-bound investments may favor Singapore-resident vehicles (which had a similar amendment but with different conditions), or direct investment, or investment through other treaty partners with more favorable treatment
- Substance compliance has become essential — Indian tax authorities scrutinize Mauritius vehicles for genuine residence (not just legal residence)
- The General Anti-Avoidance Rule (GAAR) in Indian tax law applies — abusive treaty shopping is challengeable
Other Useful Mauritius Treaties
Mauritius’s treaty network beyond India includes:
- Sub-Saharan Africa: South Africa, Uganda, Mozambique, Zimbabwe, Ghana, and others in force — useful for African investment structures (note: some treaties such as Senegal and Zambia have been terminated, and others such as Kenya, Nigeria, and Tanzania are signed but not yet in force — always confirm current status)
- Middle East and Asia: UAE, Singapore, Pakistan, Sri Lanka, Bangladesh, Thailand, Vietnam, China (limited)
- Europe: France, Germany, UK, Belgium, Luxembourg, Cyprus, Italy, Sweden (varied scope)
- Others: Mauritius continues to negotiate and update treaties
The African network is the most distinctive part of the treaty portfolio in 2026 — supporting Mauritius as a hub for African investment flows.
Use Cases for Mauritius in 2026
Use case 1: African investment hub
An investor or operating group with multiple African investments uses Mauritius as a holding hub:
- Investments in African subsidiaries held through Mauritius GBC
- Treaty access to multiple African jurisdictions reduces withholding tax on dividends, royalties, interest, capital gains
- Mauritius substance maintained through management company
- PER reduces effective tax on qualifying dividend / interest flows
Use case 2: Africa-focused operating business
An operating business serving African markets uses Mauritius as the operational holding entity, with substantive operations in target African countries. Treaty access reduces friction.
Use case 3: Grandfathered India structures
Pre-2017 India investments held in Mauritius GBC continue to benefit from grandfathered treaty positioning. Maintaining the structure (vs. restructuring) preserves the historical advantage.
Use case 4: Asian fund / investment vehicles
Specific fund structures (private equity, venture capital, infrastructure) sometimes use Mauritius for combination of treaty network, regulatory framework, and management company infrastructure.
Use case 5: Shipping and aircraft
Mauritius offers specific regimes for ship and aircraft holding and operations — these niches use the structures.
When Mauritius Does NOT Make Sense in 2026
- New India investments expecting capital gains exemption. Post-2017 treaty position eliminates this advantage.
- Pure operating SaaS, e-commerce, or services business without African/Asian-investment connection. Wyoming LLC, Estonia OÜ, Cyprus Ltd serve better at lower cost.
- Founder solo structure without group-level treaty needs. Mauritius’s substantial annual cost is overkill for simple operating structures.
- Stripe / Mercury-dependent businesses. Mauritius companies typically do not access these.
- Businesses where banking simplicity matters. Mauritius banking is workable but harder than US/EU/HK options.
Mauritius Formation Process
Step 1: Engage Mauritius management company / company secretary
Mauritius requires engagement of a licensed Management Company (MC) for GBC structures. The MC provides:
- Application to FSC for the Global Business Licence
- Mauritius-resident directors (typically 2)
- Registered office
- Accounting and administrative support
- Bank account introduction
- Ongoing statutory compliance
Major Mauritius MCs include international names (Trident Trust, Vistra, IQ-EQ, Saffery Champness, Bolder, etc.) and local firms.
Step 2: KYC and structuring
The MC performs full KYC on the proposed beneficial owners and directors. Structuring discussions cover:
- GBC vs Authorised Company choice
- Intended activities and treaty positioning
- Substance requirements proportionate to activities
- Source of funds documentation
Step 3: Incorporation and licensing
- Apply to FSC for Global Business Licence (for GBC) or Authorised Company licence
- Incorporate the company with the Corporate and Business Registration Department
- Timeline: typically 4-8 weeks for GBC; 2-4 weeks for Authorised Company
Step 4: Bank account opening
GBCs must have principal bank account in Mauritius. Common Mauritius banks for GBCs:
- State Bank of Mauritius (SBM)
- Mauritius Commercial Bank (MCB)
- AfrAsia Bank
- Bank One
- Standard Bank Mauritius
- HSBC Mauritius (limited; institutional)
Account opening typically takes 4-12 weeks, with comprehensive KYC. Introduction by the MC materially helps.
Step 5: Operations and ongoing substance
- Board meetings in Mauritius (typically quarterly)
- Accounting and audit in Mauritius
- Annual FSC filings
- Annual tax return
- Ongoing CIGA documentation
What Mauritius Setup Actually Costs
| Cost Item | GBC (USD) | Authorised Company (USD) |
|---|---|---|
| Application / formation | 3,000-6,000 | 2,000-4,000 |
| FSC licensing | Annual fees included | Annual fees included |
| Management company (annual) | 6,000-15,000 | 3,000-6,000 |
| Annual audit (Mauritius) | 3,000-12,000+ | Not always required |
| Mauritius resident director fees | Included in MC | N/A |
| Registered office | Included in MC | Included |
| Accounting | 2,000-8,000 | 1,500-5,000 |
| Bank account opening assistance | 500-2,000 | 500-2,000 |
| FSC annual fee | Typically USD 1,500 | Typically USD 350 |
| Tax filings | 500-2,500 | Minimal (no tax filing) |
| Year 1 total | USD 15,000-40,000 | USD 6,000-15,000 |
| Annual ongoing | USD 12,000-30,000 | USD 5,000-12,000 |
Mauritius is materially more expensive than Wyoming LLC, Estonia OÜ, or BVI BC. The cost is justified when treaty access, substance, and the specific use case warrant it.
Common Mistakes Founders Make with Mauritius
Mistake 1: Forming a GBC expecting old India treaty advantages. The 2017 treaty change eliminated the capital gains exemption for new investments. Pre-2017 grandfathering applies only to investments existing at the cutoff.
Mistake 2: Skimping on substance. Without genuine substance, the GBC may fail to qualify as Mauritius tax-resident — losing treaty access and PER. Substance is gate-keeping, not optional.
Mistake 3: Mismatching GBC and Authorised Company use cases. Authorised Company is incompatible with treaty claims; GBC requires real substance. Confusion between the two leads to structures that don’t deliver expected benefits.
Mistake 4: Underestimating ongoing cost. The annual USD 12,000-30,000 GBC cost is much higher than alternatives. For structures generating modest income, this can wipe out the tax benefit.
Mistake 5: Choosing Mauritius for businesses unconnected to its treaty network. Mauritius’s value is treaty access (India, Africa, certain Asia). A business with no India / Africa connection gains little from Mauritius vs simpler alternatives.
Mistake 6: Ignoring source-country GAAR and treaty abuse rules. Indian GAAR, African anti-abuse provisions, and OECD MLI (Multilateral Instrument) apply. Structures designed primarily for treaty shopping without commercial substance face material challenge.
Mistake 7: Not coordinating with the underlying investment jurisdiction’s tax rules. A Mauritius structure that’s clean in Mauritius but creates problems in the underlying investment jurisdictions (India, Kenya, Nigeria, etc.) defeats the purpose.
Frequently Asked Questions
Is Mauritius on the EU “non-cooperative” list? No. Mauritius exited the FATF grey list on 21 October 2021 and was removed from the EU list of high-risk third countries effective 7 January 2022, and has not been re-listed since. Mauritius has implemented OECD/EU-aligned transparency and substance frameworks. (As with any jurisdiction, confirm current status before relying on the specific positioning.)
Does Mauritius participate in CRS? Yes. Account information is reported to relevant tax authorities under the Common Reporting Standard.
Is Mauritius FATCA-compliant? Yes. Mauritius has implemented FATCA reporting for US persons.
Can I form a Mauritius company without visiting Mauritius? Yes, through the management company. Bank account opening sometimes requires in-person meeting depending on the bank.
What’s the minimum substance for a small GBC? Even for small GBCs, the basic substance package (2 Mauritius-resident directors, accounting in Mauritius, audit in Mauritius, board meetings in Mauritius) is required. Quality MCs provide the basic package; additional substance (real employees, larger office) may be needed for higher-revenue structures.
Can a Mauritius company own real estate in Africa? Yes, subject to the host country’s foreign investment rules and Mauritius’s substance requirements regarding the type of activity.
What is the corporate tax rate for a GBC’s Mauritius-source income? 15% headline. PER does not apply to Mauritius-source income.
Can I use Mauritius for crypto activities? Mauritius has been developing a Virtual Asset and Initial Token Offering Services Act (2021) regulatory regime for crypto. Specific crypto businesses require FSC licensing. Discuss with Mauritius regulatory counsel.
