Why Mauritius? The Strategic Advantage in 2026
Mauritius is one of the few international financial centres that simultaneously sits on the FATF white-list, maintains OECD BEPS alignment, offers genuine treaty access through 45+ DTAs, and delivers an effective corporate tax rate of approximately 3% on qualifying foreign-source income. That combination — credible regulation, treaty network, and low-friction tax efficiency — is what separates Mauritius from cheaper alternatives that carry reputational or compliance risks your counterparties and banks will not tolerate.
The legal framework is a practical hybrid: English common law governs corporate and commercial matters under the Companies Act 2001, while French civil law influences the property and contract environment. That dual inheritance makes Mauritius structurally familiar to investors from Commonwealth jurisdictions, continental Europe, and Francophone Africa alike.
The regulatory ecosystem is well-established and internationally recognised:
- Financial Services Commission (FSC): Licenses and supervises all GBC and AC entities, management companies, and financial service providers
- Mauritius Revenue Authority (MRA): Administers tax affairs including the partial exemption regime and DTA treaty access confirmations
- Bank of Mauritius (BoM): Regulates the banking sector including MCB, AfrAsia Bank, and SBM (Mauritius) Ltd
- OECD alignment: Mauritius has adopted the Multilateral Instrument (MLI) and implemented BEPS minimum standards
- Political and institutional stability: Ranked consistently among Africa's most stable economies and governance environments
The banking infrastructure is a practical differentiator. MCB, AfrAsia Bank, and SBM offer multi-currency accounts with SWIFT correspondent networks connecting to USD, EUR, GBP, and African clearing systems — which matters considerably when your GBC is channelling investment flows into Kenya, Nigeria, or South Africa.
Tax Efficiency: The 80% Partial Exemption Explained
The headline 15% corporate income tax rate drops to an effective approximately 3% on specified foreign-source income through the 80% partial exemption — but only when the economic substance conditions are met. This is not a negotiated incentive or a special ruling; it is the standard statutory mechanism available to all GBCs that qualify under the Income Tax Act as administered by the MRA.
The mechanics are straightforward: 80% of qualifying income is exempt from corporate tax, leaving 20% subject to the 15% CIT rate. Twenty percent multiplied by fifteen percent equals three percent effective rate on that income stream.
Income categories eligible for the 80% partial exemption include:
- Foreign-source dividends (provided no withholding tax credit is claimed on the same income)
- Foreign-source interest income
- Profits attributable to a foreign permanent establishment
- Income from dealing in securities listed on a foreign stock exchange
- Leasing income from aircraft or ships used in international transport
- Royalties and licence fees derived from intellectual property (subject to BEPS-compliant IP box conditions)
- Gains arising from the sale of securities (including equity and debt instruments)
What disqualifies a company from the partial exemption:
- Failure to meet economic substance requirements (directed and managed from Mauritius, qualified staff, proportionate expenditure)
- Income sourced from within Mauritius rather than foreign sources
- Claiming a foreign tax credit on income for which the exemption is also claimed — you cannot stack both benefits on the same income
The MRA assesses substance on an annual basis. A shell company with no real presence in Mauritius, no qualifying employees, and board meetings held via rubber-stamp signatures will not sustain the exemption claim under scrutiny.
Treaty Network: 45+ DTAs for Cross-Border Investment
Mauritius's 45+ Double Taxation Avoidance Agreements are the primary reason sophisticated businesses choose a GBC over a cheaper Authorised Company. The DTA network converts Mauritius from a tax-efficient vehicle into a treaty-protected structure — and that protection is what your fund administrators, legal counsel, and counterparties in treaty partner countries will require before giving the structure formal recognition.
Key treaty partners and their relevance:
| Treaty Partner | Key Benefit |
|---|---|
| India | WHT reduction on dividends and interest; capital gains now taxed in India for shares acquired post-April 2017 |
| China | Reduced WHT rates on dividends (5%), interest (10%), royalties (10%) |
| South Africa | Dividend WHT reduction; critical for Southern African holding structures |
| United Kingdom | Dividend and interest benefits; useful for UK-Mauritius group structures |
| Singapore | Reduced WHT on dividends and royalties |
| Kenya, Uganda, Rwanda | East Africa investment corridor protection |
| France, Germany, Luxembourg | European investment structuring |
| UAE, Qatar, Bahrain | Gulf corridor structuring |
Anti-abuse provisions you must understand:
The India–Mauritius DTAA Protocol (effective April 2017) is the most significant treaty modification in recent history. India now has taxing rights over capital gains arising from shares of Indian companies acquired after April 1, 2017. For shares acquired before that date, the grandfathering provisions continue to apply. This is not a reason to avoid a Mauritius-India structure — it changes the structuring calculus for equity exits but does not eliminate the DTA's value for dividend flows, interest, and royalties.
The Principal Purpose Test (PPT), implemented through the OECD's Multilateral Instrument, now applies to most Mauritius DTAs. If one of the principal purposes of a transaction or arrangement is to obtain treaty benefits, those benefits can be denied. The practical response is genuine substance: a GBC with real directors in Mauritius, real management decisions being made locally, and proportionate economic activity will survive PPT scrutiny. A letterbox company will not.
The General Anti-Avoidance Rule (GAAR) within Mauritius domestic law provides an additional layer of scrutiny for arrangements structured primarily to avoid tax. Working with qualified advisors who understand both the treaty provisions and the domestic GAAR is not optional — it is the baseline.
GBC vs Authorised Company (AC): Which Structure Fits?
Choose a GBC if you need Mauritius tax residency and treaty access. Choose an AC if management and control sits abroad and you do not need treaty benefits — it is simpler and cheaper to maintain, but it is tax-neutral for the company rather than tax-efficient. The AC does not pay Mauritius corporate income tax precisely because it is not Mauritius tax-resident — but your home country obligations apply in full, and you get no DTA protection from the Mauritius side.
GBC vs AC Comparison Table:
| Feature | GBC | AC |
|---|---|---|
| Tax Residency | Mauritius tax-resident | Non-resident for tax purposes |
| Corporate Income Tax | 15% (effective ~3% with partial exemption) | Not subject to Mauritius CIT |
| Treaty Access (DTAs) | Yes — 45+ DTAs available | No |
| FSC License Required | Yes — Global Business Licence | Yes — Authorised Company registration |
| Management Company | Mandatory — FSC-licensed | Mandatory — FSC-licensed |
| Resident Directors | Minimum 2 Mauritius-resident directors | Not required (but management must be abroad) |
| Economic Substance | Required to sustain partial exemption | Not applicable (no tax residency claimed) |
| Annual Audit | Mandatory (IFRS compliant) | Not required |
| Bank Account | Must maintain principal bank account in Mauritius | Can bank internationally |
| Annual Compliance Cost | Higher (audit, substance, 2 directors) | Lower |
| Setup Timeline | 3–4 weeks post-KYC clearance | 2–3 weeks post-KYC clearance |
| Typical Annual Cost | $4,000–$8,000 (excluding substance costs) | $2,000–$3,500 |
| Best For | Holding companies, treaty-access structures, IP holding | Trading intermediaries, consultancy hubs, cost-sensitive phase-one structures |
The AC was created in 2011 when the previous GBC2 category was restructured. It carries no tax residency and no tax liability in Mauritius, but it is not a zero-risk structure — your home country will tax you as if the AC's income belongs to you unless your domestic rules say otherwise.
When to Choose a GBC (3 Scenarios)
Scenario 1: Holding company for African or Asian investments requiring DTA protection You are building a portfolio of equity positions across Sub-Saharan Africa — Kenya, Rwanda, Nigeria, Ghana. Dividend repatriation from those jurisdictions is subject to withholding taxes that Mauritius DTAs can reduce or eliminate. Your investors and legal counsel in those jurisdictions expect a Mauritius HoldCo — it is the recognised, treaty-protected holding layer for that region.
Scenario 2: SaaS or IP company channelling royalty flows through a treaty-protected vehicle Your intellectual property — software licences, patents, proprietary algorithms — generates royalties from operating entities across multiple jurisdictions. A GBC holding the IP and licensing it to subsidiaries benefits from DTA-reduced withholding taxes on those royalty flows. The IP box conditions under the partial exemption regime mean the effective tax burden on qualifying royalty income can approach 3% — provided BEPS-compliant substance exists in Mauritius.
Scenario 3: Fund management or investment advisory with a multi-continent investment mandate A fund manager with a 45+ country investment reach needs a jurisdiction that treaty partners will recognise. Mauritius GBC gives the fund entity DTA access that a UAE free zone or a BVI vehicle cannot provide. FSC-licensed fund structures are increasingly a requirement from institutional investors in Africa and Asia who conduct due diligence on the fund's domicile.
When to Choose an AC (3 Scenarios)
Scenario 1: Pure holding vehicle where your home country tax credit eliminates the treaty need Some jurisdictions operate participation exemptions or territorial tax systems that exempt foreign-source dividends regardless of the source country. If your home country gives you a full exemption on dividends received from a Mauritius vehicle irrespective of the DTA, an AC achieves the same structural result at lower cost.
Scenario 2: International trading or consultancy not requiring Mauritius tax residency You are building a service company that will contract with clients globally, invoicing from a low-friction jurisdiction. You do not need Mauritius treaty protection because your clients are not in DTA-partner countries — you need a credible, FSC-regulated entity in a well-regarded jurisdiction. An AC satisfies that requirement at significantly lower annual cost.
Scenario 3: Cost-sensitive startup testing the Mauritius structure before committing to full GBC substance A founder testing whether their business model generates sufficient income to justify full GBC substance costs may start with an AC — lower compliance burden, lower annual cost, and a clear upgrade path. When revenues justify the substance investment and the DTA access becomes operationally valuable, migrating to a GBC structure through the local partner network is achievable.
Mauritius GBC vs Singapore vs Hong Kong vs UAE
For the same level of regulatory credibility and treaty access, Singapore costs 2–3x more to maintain than Mauritius and requires demonstrably higher substance expenditure to satisfy IRAS Economic Substance requirements. Hong Kong's tax residency is harder to establish for non-Hong Kong businesses, and UAE free zone structures — while low-cost — provide a treaty network that is substantially thinner than Mauritius's 45+ DTAs for African investment corridors.
Jurisdiction Comparison Table:
| Feature | Mauritius GBC | Singapore | Hong Kong | UAE Free Zone / RAK ICC |
|---|---|---|---|---|
| Effective Tax Rate | ~3% (with partial exemption) | 17% (incentives available) | 16.5% (territorial) | 9% (CT post-2023; free zone entities may qualify for 0%) |
| Headline CIT | 15% | 17% | 16.5% | 9% (UAE Corporate Tax from 2023) |
| Treaty Network | 45+ DTAs | 90+ DTAs | 45+ DTAs | 130+ DTAs (UAE) |
| Africa DTA Coverage | Strong (20+ African DTAs) | Limited | Limited | Growing but thinner than Mauritius for SSA |
| Annual Substance Cost | $6,000–$15,000 (activity-dependent) | $20,000–$50,000+ | $15,000–$35,000+ | $5,000–$15,000 (free zone) |
| Banking Access | Good (MCB, AfrAsia, SBM) | Excellent | Excellent | Moderate (improving) |
| Audit Requirement | Yes (GBC) | Yes | Yes | Varies by free zone |
| Setup Timeline | 3–4 weeks | 4–6 weeks | 3–5 weeks | 2–4 weeks |
| Annual Maintenance Cost | $4,000–$8,000 (excl. substance) | $8,000–$20,000+ | $6,000–$15,000+ | $3,000–$8,000 |
| OECD BEPS Alignment | Yes — MLI signatory | Yes | Yes | Yes (post-2023 reforms) |
| Regulator | FSC Mauritius | ACRA / IRAS | CR / IRD | Free Zone Authority / MoE |
| Best For | Africa/Asia holding, IP holding, fund management | Asia-Pacific hub, regional HQ | China-facing structures | Gulf region, light-substance holding |
The UAE's free zone regime has become more complex since the introduction of UAE Corporate Tax in June 2023. Qualifying Free Zone Persons can still access a 0% rate on qualifying income, but the conditions are increasingly substance-intensive and the definition of "qualifying income" requires careful analysis. For businesses with African investment corridors specifically, Mauritius's DTA network with Sub-Saharan African nations remains unmatched among similarly cost-efficient jurisdictions.
Practical Use Cases & Sample Structures
Here are three real-world Mauritius structures we coordinate for clients through our local partner network. These are not theoretical — they reflect the actual corporate architectures that work within Mauritius's regulatory framework and sustain scrutiny from both the FSC and counterparty due diligence teams.
Holding Company for African Investments
The structure:
[Founder / Investor (home country)]
|
▼
[Mauritius GBC — HoldCo]
(FSC-licensed, Mauritius tax-resident)
(2 resident directors, local board meetings)
(Principal bank account: MCB or AfrAsia)
|
_____|_____
| | |
▼ ▼ ▼
[Kenya OpCo] [Nigeria OpCo] [Ghana OpCo]
Why this works:
The Mauritius–Kenya DTA reduces withholding tax on dividends paid by the Kenyan subsidiary to the Mauritius HoldCo. Similar protections apply under the Mauritius–South Africa DTA for Southern African operations. Capital gains on disposal of equity in the African subsidiaries may be sheltered depending on the specific DTA provisions.
Substance requirements for this structure:
The HoldCo must hold board meetings in Mauritius with 2 resident directors physically present. Investment decisions — approving capital calls, sanctioning dividend declarations, approving subsidiary board appointments — must be documented as occurring in Mauritius. Financial statements and records must be maintained at the Mauritius registered office.
Key considerations:
- Post-2017 India-facing capital gains cannot be sheltered through Mauritius — this structure is Africa-focused
- Transfer pricing documentation is required if the HoldCo charges management fees to subsidiaries
- Nominee directors are acceptable but must exercise genuine oversight — FSC scrutinises rubber-stamp board minutes
- DTA access under the PPT requires that the Mauritius HoldCo has genuine commercial rationale beyond treaty benefit access
SaaS / IP Holding Structure
The structure:
[Founder / Parent Entity (home country)]
|
▼
[Mauritius GBC — IP HoldCo]
(Owns IP: software, patents, algorithms)
(Licenses IP to operating entities)
(FSC-licensed, 2 resident directors)
|
_______|_______
| | |
▼ ▼ ▼
[UK OpCo][India OpCo][Singapore OpCo]
(pays royalties to Mauritius IP HoldCo)
Tax efficiency mechanics:
The Mauritius IP HoldCo receives royalty income from operating entities. Under applicable DTAs, withholding tax on royalties paid to Mauritius is reduced — for example, from India the DTA provides reduced WHT rates on royalties. The royalty income received by the Mauritius GBC qualifies for the 80% partial exemption (subject to BEPS-compliant IP conditions), producing an effective tax rate approaching 3% on that income.
BEPS compliance is non-negotiable here:
The OECD's BEPS Action 5 requires that IP tax incentives be linked to substantial activity — the nexus approach. The Mauritius IP box regime has been updated to align with this standard. The GBC must demonstrate genuine R&D or development activity contributing to the IP value — a pure holding arrangement with no development function will fail scrutiny.
Transfer pricing requirements:
Royalty rates between the Mauritius IP HoldCo and its operating entity licensees must be arm's length. A functional analysis documenting the IP HoldCo's contributions (development, enhancement, maintenance, protection, exploitation — the DEMPE functions) is required. Where the IP HoldCo contributes limited DEMPE functions, limited returns are defensible — but the structure must reflect economic reality.
International Trading & Consultancy
The structure:
[Founder / Service Provider (home country)]
|
▼
[Mauritius GBC — Trading / Consultancy Hub]
(Contracts with international clients)
(Issues invoices in USD/EUR/GBP)
(Multi-currency banking: MCB / AfrAsia)
(Provides management services to group entities)
How this structure functions:
The Mauritius GBC acts as the contracting entity for international clients, capturing margin at the Mauritius level. For group procurement functions, the GBC purchases goods or services from suppliers globally and on-sells to group entities — the trading margin is booked in Mauritius. For advisory and consultancy mandates, the GBC invoices clients directly.
Critical compliance considerations:
- Functional analysis required: the GBC must perform genuine trading or advisory functions in Mauritius — if all decisions are made by the founder in London, the structure faces permanent establishment risk in the UK
- Economic substance for a trading GBC means qualified staff in Mauritius executing the relevant commercial activities — not just a registered office and a management company
- Transfer pricing documentation for any intra-group transactions: if the GBC is charging management fees to or purchasing from related parties, arm's length pricing with contemporaneous documentation is required
- Multi-currency banking through MCB or AfrAsia is typically more accessible for trading companies than for holding structures — the transaction flow provides a clearer KYC narrative for bank due diligence
Step-by-Step Formation Process
A GBC can be operational in 3–4 weeks once KYC is cleared — an AC in 2–3 weeks. The timeline bottleneck is almost never the registration itself; it is the KYC and business plan review by the management company and the FSC. Submitting incomplete or inconsistent documents is the single most common cause of delay.
Pre-Incorporation: KYC, Business Plan & Name Reservation
KYC documents required from each beneficial owner, director, and shareholder:
- Certified copy of passport (certified by a notary, lawyer, or bank — not self-certified)
- Certified proof of residential address (utility bill or bank statement, not older than 3 months)
- Bank reference letter (from an established financial institution confirming good standing)
- CV / professional biography (summarising business background and relevant experience)
- Source of funds declaration (detailed explanation of how the investment capital was generated)
- Source of wealth declaration (broader statement of how the individual's net worth was accumulated)
- For corporate shareholders: full corporate KYC chain up to ultimate beneficial owner
Business plan requirements:
The business plan is not a formality — the FSC and your management company will review it carefully. It must cover:
- Precise description of the company's intended activities (general descriptions like "investment holding" are insufficient without detail)
- Projected revenue and expense flows for years 1–3, with realistic assumptions
- Jurisdiction rationale: why Mauritius is the appropriate location for this business activity
- Description of counterparties (clients, suppliers, investee companies) by jurisdiction
- Explanation of how economic substance will be maintained in Mauritius
Name reservation:
Submit your proposed company name to the Corporate and Business Registration Department (CBRD) — the Registrar of Companies under the Companies Act 2001. The name must not conflict with an existing registered name and must not be misleading as to the nature of the company's activities. Name reservation is a prerequisite before the FSC application can proceed.
FSC Application & Management Company Appointment
The appointment of an FSC-licensed Management Company is mandatory for both GBCs and ACs — there is no route to incorporation without one. The management company is not merely a registered office provider; it is your legal gatekeeper to the FSC, your compliance supervisor, and the entity responsible for submitting your annual compliance returns.
What the FSC application covers:
- Application for a Global Business Licence (for a GBC) or Authorised Company registration (for an AC)
- Submission of all KYC documents for beneficial owners, directors, and shareholders
- Business plan and financial projections
- Proposed constitutional documents (Constitution / Memorandum and Articles)
- Details of proposed directors (with evidence of Mauritius residency for the 2 resident directors required for a GBC)
- Management company engagement letter
FSC review process:
- Management company conducts its own KYC review (typically 1–2 weeks)
- FSC application submitted by management company on behalf of the applicant
- FSC reviews application (typically 1–2 weeks for standard applications)
- FSC may request additional information (adds 1–2 weeks)
- Approval and issuance of Global Business Licence or AC registration certificate
Common reasons for FSC application delays or rejections:
- Vague or internally inconsistent business plan
- Beneficial owner KYC documents not properly certified or too old
- Source of funds narrative that doesn't align with the declared business history
- Proposed company name conflicts or misleading descriptions
- Insufficient clarity on how Mauritius substance will be maintained
- Beneficial owners from high-risk jurisdictions requiring enhanced due diligence
The Financial Services Act 2007 governs the FSC's licensing authority and the management company's obligations. Understanding that the management company has statutory obligations to the FSC — not just contractual obligations to you — is important. If your KYC narrative is deficient, the management company is legally required to decline or escalate, regardless of your commercial timeline.
Registration, Corporate Documents & Timeline
Documents produced upon successful incorporation:
- Certificate of Incorporation issued by the Corporate and Business Registration Department (CBRD/ROC)
- Global Business Licence (for GBC) or Authorised Company Certificate (for AC) issued by FSC
- Constitution / Memorandum and Articles of Association
- Register of Directors and Officers
- Register of Shareholders / Members
- Register of Beneficial Owners
- Share certificates
- Appointment resolutions for initial directors and officers
- First board meeting minutes
Consolidated timeline from KYC submission to operational status:
| Stage | GBC | AC |
|---|---|---|
| KYC document preparation and certification | 1–2 weeks | 1–2 weeks |
| Management company KYC review | 1–2 weeks | 1 week |
| Name reservation (CBRD) | 2–3 days | 2–3 days |
| FSC application submission and review | 1–2 weeks | 1 week |
| Certificate of Incorporation issued | 2–3 days post-approval | 2–3 days post-approval |
| Corporate documents drafted and executed | 3–5 days | 3–5 days |
| Total from KYC submission | 3–4 weeks | 2–3 weeks |
| Bank account opening (separate process) | 4–8 weeks | 4–8 weeks |
Statutory registers must be maintained at the registered office in Mauritius. The management company typically maintains these on your behalf as part of the company secretarial service. Annual updates to the registers — particularly the Register of Beneficial Owners — are a regulatory obligation under the Companies Act 2001 and non-compliance triggers FSC scrutiny.
Costs & Timelines (2026)
GBC formation typically runs $3,500–$6,500 in setup costs, with $4,000–$8,000 in annual maintenance depending on substance level. AC costs run $2,500–$4,000 setup with $2,000–$3,500 annually. These figures cover corporate infrastructure — they do not include the economic substance costs (office space, qualified staff, local expenditure) that are required to sustain the GBC's partial exemption claim.

| Economic substance reporting | $300–$600 | N/A |
| Annual Total (excl. substance) | $4,000–$8,000 | $2,000–$3,500 |
Note: These figures cover the corporate compliance layer. Economic substance costs (office rental, staff, local expenditure) for GBCs are in addition and are detailed in the Substance Budgets section below.
Nominee Director & Substance Costs
A GBC requires a minimum of 2 directors who are Mauritius residents. In practice, most GBCs use nominee directors provided by or introduced through their management company — qualified professionals who attend board meetings, review board papers, and execute their fiduciary obligations.
What nominee directors cost:
- Nominee director fee: $1,000–$2,000 per director per year (standard)
- For higher-complexity structures (fund structures, multi-layered groups): $2,500–$4,000 per director per year
- Two directors required for a GBC = $2,000–$8,000/year for directorial services alone
Substance-lite vs substance-medium budget implications:
The FSC does not publish a rigid substance threshold — it assesses proportionality. A Mauritius HoldCo receiving passive dividend income needs less substance than a Mauritius trading company actively contracting with third parties. That said, the FSC's Economic Substance Guidance makes clear that a company cannot sustain its substance claim on nominee directors alone — there must be proportionate expenditure and activity in Mauritius.
A "substance-lite" GBC — a pure holding company receiving dividends — can maintain credible substance at lower cost than a "substance-medium" advisory or SaaS company that must demonstrate active management decisions being made in Mauritius. The distinction matters enormously for your annual budget.
Tax Regime & Economic Substance (The 2026 Reality)
The 3% effective tax rate is real — but only if the company conducts its core income-generating activities in Mauritius with real people and real spending. The 2019 Finance Act eliminated the old GBC1 deemed foreign tax credit system precisely because it did not require genuine substance. What replaced it — the 80% partial exemption tied to substance conditions — is more demanding to maintain but more robust to international scrutiny.
15% CIT + 80% Partial Exemption: How It Works
The Income Tax Act provides that 80% of specified foreign-source income is exempt from corporate income tax. The remaining 20% is taxed at the standard 15% rate. The arithmetic produces an effective rate of 3% on qualifying income streams.
Step-by-step mechanics:
- GBC receives $1,000,000 in qualifying foreign-source dividends
- 80% exemption = $800,000 exempt
- Taxable amount = $200,000
- CIT at 15% on $200,000 = $30,000
- Effective tax rate = 3% of $1,000,000
The foreign tax credit interaction:
You cannot simultaneously claim the 80% partial exemption AND a foreign tax credit on the same income. If the source country has withheld tax and you claim a foreign tax credit for that withholding, the partial exemption does not apply to that income stream. Your tax advisor must model which treatment (exemption vs credit) produces the lower Mauritius tax liability — the answer depends on the source country WHT rate.
What disqualifies income from the partial exemption:
- Income sourced from within Mauritius (domestic income is taxed at the full 15%)
- Income from activities that fail the substance test (CIGA not conducted in Mauritius)
- Income on which a foreign tax credit is simultaneously claimed
- Passive income from arrangements structured primarily to access the exemption without genuine commercial activity
The MRA's administration of the partial exemption is not purely self-assessment — it can and does challenge GBCs whose substance claims are thin. Annual tax returns must be filed with the MRA within six months of the financial year end, and the MRA has the authority to request substantiation of exemption claims.
Withholding Tax: Dividends, Interest & Royalties
Mauritius does not impose withholding tax on dividends paid by a GBC to non-resident shareholders. This is one of the most practically significant advantages of the Mauritius regime — a GBC can repatriate profits to its parent entity or shareholders overseas without any Mauritius-level withholding tax deduction.
WHT summary for outbound payments from a Mauritius GBC:
| Payment Type | Mauritius WHT (to non-residents) | DTA Impact |
|---|---|---|
| Dividends | 0% | No WHT to reduce — already zero |
| Interest | 15% (standard rate) | Reduced to 0–10% under most DTAs |
| Royalties | 15% (standard rate) | Reduced to 5–15% under most DTAs |
| Management fees | 0% (generally) | Treaty provisions vary |
| Capital gains | Not subject to Mauritius CGT | Source country may tax |
Treaty shopping risk on interest and royalties:
Even where a DTA reduces WHT on interest or royalty payments received by the GBC, the GBC must itself be the beneficial owner of that income — not a conduit passing the income to a parent entity in another jurisdiction. Where the MRA or the source country tax authority determines that the GBC is acting purely as a conduit, beneficial ownership will be denied and full WHT rates may apply. Substance and economic reality are the defence.
Economic Substance: What It Means in Practice
The FSC's Economic Substance Guidance defines the minimum conditions a GBC must satisfy to demonstrate genuine management and control from Mauritius. These conditions directly determine whether the company can sustain its tax residency, partial exemption claim, and DTA access.
The six substance pillars the FSC assesses:
-
Core Income-Generating Activities (CIGA) conducted in Mauritius: The company's primary value-creating activities must take place in Mauritius — not merely be reported as occurring there. For a holding company, this means investment decisions being made in Mauritius. For an IP company, it means development and licensing decisions being made locally.
-
"Directed and managed from Mauritius" test: Board meetings with an agenda reflecting substantive management decisions must be held in Mauritius with a quorum of physically-present resident directors. Video conferencing does not satisfy the physical presence requirement. Board minutes must evidence genuine deliberation — not rubber-stamp approval of decisions made elsewhere.
-
Adequate number of qualified employees in Mauritius: The FSC does not specify a headcount minimum — it requires proportionality to the scale and nature of activities. A passive holding company may sustain substance with 2 resident directors and minimal staff. A SaaS licensing company with 15 licensees globally will need demonstrably more.
-
Proportionate expenditure incurred in Mauritius: The company must spend proportionately in Mauritius — office rental, staff salaries, service provider fees, and operational costs. Substance cannot be demonstrated where the only Mauritius-based cost is the management company annual fee.
-
Principal bank account in Mauritius: The GBC's primary operating and treasury account must be held with a Mauritius-licensed bank (MCB, AfrAsia, SBM, or another Bank of Mauritius-regulated institution). Offshore banking does not satisfy this requirement.
-
Accounting records maintained at the Mauritius registered office: Financial books and records must be kept in Mauritius. Management company-maintained records at the registered office satisfy this requirement for most GBC structures.
The practical takeaway: Substance is not a compliance checkbox. It is an ongoing operational reality that the FSC can assess at any point through its supervisory function. Management companies that offer "substance-light" arrangements — nominee directors attending one board meeting per year with pre-signed minutes — are creating long-term structural risk that will emerge during FSC inspections or when treaty partner tax authorities query the GBC's substance.
Substance Budgets: Holding, SaaS, Advisory
These are indicative annual cost ranges. Actual costs depend on the scale of activities, the FSC's assessment of what constitutes proportionate substance for your specific GBC, and the management company's service model. All figures are in USD.
| Cost Item | Holding GBC | SaaS / IP GBC | Advisory / Trading GBC |
|---|---|---|---|
| Registered office (managed) | $800–$1,200 | $1,000–$2,000 | $1,500–$3,000 |
| 2 Nominee / resident directors | $2,000–$4,000 | $3,000–$6,000 | $3,000–$6,000 |
| Company secretary | $500–$800 | $600–$1,000 | $600–$1,000 |
| Local part-time administrator / compliance officer | $1,500–$3,000 | $3,000–$6,000 | $4,000–$8,000 |
| Physical office space (if applicable) | Minimal (managed office) | $2,000–$4,000/year | $3,000–$6,000/year |
| Board meetings (logistics, minutes) | $500–$1,000 | $1,000–$2,000 | $1,000–$2,000 |
| Indicative Annual Substance Cost | ~$6,000–$10,000 | ~$12,000–$20,000 | ~$15,000–$25,000 |
Add corporate compliance costs (management company annual fee, audit, MRA return, FSC returns) of $4,000–$8,000 on top of substance costs to arrive at total annual operational cost.
A holding GBC with minimal activity and 2 nominee directors conducting 2–3 board meetings per year represents the lower end of the substance cost spectrum. An advisory GBC actively contracting with clients and making frequent commercial decisions requires commensurately more substantive presence in Mauritius to sustain FSC and MRA scrutiny.
Banking in Mauritius: Requirements, KYC & Decision Matrix
Banking is the most common bottleneck in the Mauritius company formation process. MCB, AfrAsia Bank, and SBM each have distinct risk appetites, minimum balance requirements, and KYC expectations — choosing the wrong bank for your business profile adds weeks to account opening and, in some cases, results in rejection that makes the next application harder.

Bank Comparison: MCB vs AfrAsia vs SBM
| Feature | MCB (Mauritius Commercial Bank) | AfrAsia Bank | SBM (Mauritius) Ltd |
|---|---|---|---|
| Minimum Balance | $25,000–$50,000 (GBC accounts) | $100,000–$250,000 (private banking) | $10,000–$25,000 |
| Account Opening Timeline | 6–10 weeks | 8–12 weeks | 4–8 weeks |
| Best For | Established trading companies, Africa-focused structures, mid-market GBCs | High-net-worth clients, private banking, fund structures with larger AUM | Smaller GBCs, startups, cost-sensitive structures |
| Rejection Risk | Moderate (conservative KYC) | Lower for qualifying clients, but minimum balance deters entry | Lower for standard GBC profiles |
| Multi-Currency | USD, EUR, GBP, ZAR, SGD, MUR and others | USD, EUR, GBP, ZAR and others; strong private banking | USD, EUR, GBP, MUR and others |
| Correspondent Network | Extensive — Citibank (USD), Deutsche Bank (EUR), Standard Chartered | Strong — Citibank, JPMorgan | Good — standard correspondent relationships |

| Physical Interview | Sometimes required | Often required for new accounts | Less commonly required |
| Bank of Mauritius Licensed | Yes | Yes | Yes |
Selecting the right bank for your profile:
MCB is Mauritius's largest commercial bank and the default choice for established GBCs with clear, documented transaction flows. Its KYC process is thorough and conservative — expect detailed questions about counterparties and business flow. For Africa-focused holding structures and trading companies with documented African counterparties, MCB's correspondent network into African clearing systems is the practical choice.
AfrAsia Bank is oriented toward private banking and wealth management. Its minimum balances are higher, but its service model is more personalised and it has appetite for fund structures and high-net-worth holding arrangements. If your GBC is a wealth structuring vehicle with significant assets, AfrAsia is the more appropriate primary relationship.
SBM offers more accessible account opening conditions for GBCs at earlier stages of development. Its correspondent network is adequate for standard international transactions but less extensive than MCB's for complex multi-currency corridors.
Account Opening: Documents, Process & Timeline
Required documents for GBC bank account opening (per UBO and director):
- Certified copy of passport
- Certified proof of residential address (not older than 3 months)
- Bank reference letter from existing bank
- CV / professional biography
- Source of funds and source of wealth declarations
- Corporate documents: Certificate of Incorporation, Global Business Licence, Constitution, Register of Directors, Register of Shareholders, Register of Beneficial Owners, Board resolution authorising account opening and signatory authorities, certified share certificates
Additional documents the bank will require regarding the company:
- Detailed business plan (aligned with the FSC application business plan)
- Projected cash flow statement for 12–24 months
- Description of anticipated counterparties (clients, suppliers) by jurisdiction
- AML/CFT compliance confirmation from management company
- Details of the management company and its FSC licence
The account opening process — step by step:
- Pre-application: Management company or banking introducer reviews your profile against each bank's risk appetite
- Application submission: Completed application form and full document pack submitted to bank's GBC/International Banking unit
- Bank KYC review: Bank's compliance team reviews documents — typically 2–4 weeks
- KYC queries: Bank requests clarifications or additional documents (almost always happens — plan for it)
- Compliance approval: Bank's AML/CFT committee approves the account
- Account activation: Account numbers issued, online banking credentials provided, initial deposit required to activate
Timeline: 4–8 weeks for standard applications. Complex structures (multi-layered ownership, high-risk jurisdictions in the ownership chain, unusual business activities) extend to 10–14 weeks.
The single most common cause of delay is a weak or inconsistent source of funds narrative. Banks apply the Bank of Mauritius AML/CFT Guidelines rigorously — if your declared source of funds does not align with your professional history and business activity, you will receive a formal request for additional evidence that resets the review clock.
Multi-Currency & Correspondent Banking
All three major Mauritius banks offer multi-currency accounts that can operate in USD, EUR, GBP, and MUR as standard. ZAR, SGD, and other currencies are available but may require specific arrangements depending on transaction volumes.
SWIFT access: All GBC bank accounts operate with SWIFT — essential for cross-border wire transfers. MCB's SWIFT code is MCBLMUMU; AfrAsia's is AFBKMUMU; SBM's is STCBMUMU.
Correspondent banking relationships:
The quality of a bank's correspondent banking relationships directly determines how efficiently your cross-border payments clear. MCB's correspondent network — including Citibank (USD), Deutsche Bank (EUR), and Standard Chartered — provides reliable clearing for USD and EUR transactions globally, with strong African corridor connectivity. For GBCs channelling investment into Kenya, Nigeria, or South Africa, MCB's African correspondent relationships are practically relevant.
Digital banking for international GBCs:
MCB Business Hub and AfrAsia's online platform support international wire transfers, statement access, and multi-currency account management remotely. Physical presence is not required for day-to-day banking operations post-account opening — which is important for GBC owners who are not resident in Mauritius.
Fintech banking and EMI accounts (Wise, Airwallex, etc.) are not substitutes for a Mauritius bank account for a GBC. The FSC requires a principal bank account at a Bank of Mauritius-licensed institution as part of the substance requirements — a fintech account does not satisfy this obligation.
Risks You Must Model
A Mauritius GBC works excellently — but only if you model these five risks before incorporating. These are not theoretical concerns; they are the issues that cause real structures to generate unexpected tax bills, regulatory scrutiny, or banking difficulties after the fact.
CFC Rules & Home Country Taxation
Controlled Foreign Company rules exist in most major economies — UK, Germany, France, South Africa, and others — and they are designed specifically to prevent residents from using foreign companies to shelter income from home country tax.
How CFC rules affect Mauritius GBC structures:
If you are a UK resident and you own more than 50% of a Mauritius GBC, HMRC's Chapter 9 CFC rules may attribute the GBC's income directly to you for UK tax purposes — regardless of whether dividends are actually paid. The same principle applies in Germany under the German CFC regime (Hinzurechnungsbesteuerung) and in South Africa under sections 9D of the Income Tax Act.
The primary defence is substance:
Most CFC regimes include a substance exemption — if the foreign company has genuine substance (qualified employees, real activities, management and control) in its jurisdiction, the CFC charge is disapplied. A Mauritius GBC that genuinely meets the FSC substance requirements is typically protected from CFC attribution under UK, German, and South African rules. But "typically protected" is not the same as "automatically protected" — your home country tax position must be analysed before you incorporate.
Country-specific CFC considerations:
- UK: Chapter 9 TCGA 1992 / Chapter 9A CTA 2010 — GBC exempt if it passes the substance test or the exempt period applies
- South Africa: Section 9D — Foreign Business Establishment exemption requires genuine substance
- Germany: AStG §§7–14 — substance test must be met; German residents with Mauritius GBCs require careful analysis
- Australia: Division 832 ITAA 1997 — active income test and substantial activity requirements
Permanent Establishment Risk
If you are managing your Mauritius GBC from your home country — making commercial decisions, signing contracts, directing activities — your home country may assert that a Permanent Establishment exists there, regardless of where the company is incorporated.
The PE tests that matter:
- Fixed place of business test: Does the GBC have a fixed place of business in your home country from which its business is wholly or partly carried on? Your home office can constitute a PE under OECD Model Tax Convention Article 5 if it is used regularly for the GBC's business activities.
- Dependent agent test: Do you, as an agent in your home country, have the authority to conclude contracts on behalf of the Mauritius GBC and exercise that authority habitually? If yes, a PE exists in your home country regardless of the GBC's Mauritius incorporation.
The practical implication:
A Mauritius GBC where the beneficial owner makes all commercial decisions from London while the Mauritius directors rubber-stamp those decisions has a London PE, not a Mauritius PE. The income is taxable in the UK. The Mauritius structure provides no protection.
Mitigation:
- Genuine authority must sit with the Mauritius-based directors — they must make, or meaningfully participate in, substantive commercial decisions
- Board meetings in Mauritius must reflect real deliberation and decision-making
- Contracts should be authorised and executed by Mauritius-based signatories where possible
- The beneficial owner should not habitually act as a signing authority or negotiating agent for the GBC from outside Mauritius
Transfer Pricing Compliance
Any transaction between your Mauritius GBC and a related party — a parent company, a subsidiary, or a company with common ownership — must be priced at arm's length. The arm's length principle requires that the price charged reflects what two independent parties dealing at arm's length would agree in comparable circumstances.
When TP documentation is required:
- GBC charges management fees to related subsidiaries
- GBC licenses IP to related companies
- GBC provides intercompany loans to related entities
- GBC acts as a purchasing or trading intermediary for related parties
Mauritius TP requirements:
Mauritius introduced formal Transfer Pricing Regulations (income year beginning on or after July 1, 2019) for companies with gross income exceeding MUR 500 million (~USD 10–11 million). Below this threshold, the arm's length standard still applies under the Income Tax Act, but formal TP documentation requirements are less prescriptive.
OECD TP Guidelines apply:
Mauritius's TP framework is aligned with OECD Transfer Pricing Guidelines. Functional analysis (what functions are performed, what assets are used, what risks are assumed), comparability analysis, and selection of the most appropriate TP method are all required components. For GBCs transacting with related parties at scale, contemporaneous TP documentation prepared before the financial year end is the defensible standard.
EU Unshell Directive / ATAD 3
The EU Unshell Directive (informally called ATAD 3) targets shell entities that lack minimum substance and are used primarily for tax avoidance. While still working through EU legislative processes as of 2026, it is relevant to any Mauritius GBC with EU-based shareholders, EU-based income sources, or EU-based counterparties.
The Unshell substance indicators:
The Directive proposes three categories of minimum substance indicators. An entity that fails these indicators is presumed to lack genuine economic activity:
- Own premises or exclusive use of premises: Physical office space in the jurisdiction
- At least one active bank account: In the EU jurisdiction — though this indicator focuses on EU entities; for Mauritius the equivalent is the principal bank account requirement
- One or more directors: Resident in the jurisdiction, with adequate knowledge and qualifications, and not employed full-time elsewhere
How a properly-substanced GBC passes:
A GBC that maintains a physical registered office (even managed), 2 qualified resident directors who actively exercise their roles, and a Mauritius bank account — and conducts genuine CIGA in Mauritius — satisfies the equivalent substance indicators. The issue arises for GBCs that exist purely on paper.
What is still under negotiation:
The Directive's precise scope, the reporting obligations, and the interaction with existing EU tax rules are still subject to Member State negotiation. The direction of travel is clear — EU members will increasingly scrutinise the substance of entities used by EU residents to hold EU-connected income. Structuring with genuine Mauritius substance is not just an FSC obligation — it is an increasingly important defence against EU regulatory reach.
GAAR / PPT Under Mauritius DTAs
The Principal Purpose Test has been incorporated into most Mauritius DTAs through the OECD's Multilateral Instrument. The PPT denies treaty benefits where it is reasonable to conclude that one of the principal purposes of an arrangement was to obtain those treaty benefits.
What the PPT means in practice:
If a Mauritius GBC is established primarily because the Mauritius-India DTA reduces withholding tax on dividends from an Indian subsidiary — and the GBC has no genuine commercial rationale beyond accessing that treaty benefit — an Indian tax authority applying the PPT could deny the DTA benefit and apply full domestic withholding tax rates.
The defence against PPT challenge:
Commercial substance and a genuine business rationale. A GBC that actively manages a portfolio of investments, employs qualified people in Mauritius, makes real commercial decisions locally, and generates genuine economic activity in Mauritius has a strong defence against PPT challenge. The treaty benefit it accesses is a consequence of its genuine Mauritius presence, not the cause of it.
Mauritius's General Anti-Avoidance Rule:
Section 94 of the Income Tax Act contains Mauritius's domestic GAAR — it empowers the MRA to disregard or re-characterise arrangements entered into primarily to obtain a tax advantage. Combined with the PPT in the DTAs, these provisions mean that purely tax-motivated structures with no economic substance face significant vulnerability. Structures with genuine commercial rationale and proper substance are not affected.
Choosing a Licensed Mauritius Management Company
Your management company is your gatekeeper to the FSC, your bank, and your compliance framework — choose wrong and you will spend years fixing it. The management company's quality, reliability, and banking relationships are more consequential to the success of your Mauritius structure than almost any other single factor.
FSC License Verification & Due Diligence Checklist
Every management company providing services to GBCs and ACs must hold an FSC Management Licence under the Financial Services Act 2007. The FSC maintains a public register of licensed entities that is searchable on the FSC website.
Due diligence checklist for management company selection:
- [ ] Verify FSC Management Licence: Confirm the licence number, licence category, and active status on the FSC public register — not just the company's own marketing materials
- [ ] Check for FSC enforcement actions: The FSC publishes enforcement actions, sanctions, and licence suspensions — search for the management company name in FSC regulatory notices
- [ ] Assess track record: Five or more years of operation as a licensed management company is the minimum recommended threshold; longer-established firms have navigated multiple regulatory cycles
- [ ] Evaluate client profile: Does the management company's existing client base align with your industry and structure? A firm specialising in fund structures may not be the right fit for a trading GBC
- [ ] Confirm banking relationships: Which banks does the management company have active relationships with? A management company without established MCB, AfrAsia, or SBM relationships will be slower and less effective at facilitating your account opening
- [ ] Review fee transparency: Obtain a full fee schedule upfront — including charges for FSC annual returns, MRA tax filings, additional board meetings, and disbursements. Opaque fee structures lead to invoice surprises
- [ ] Request client references: Established management companies with satisfied clients can provide references. Reluctance to do so is a warning sign
- [ ] Assess compliance capability: The management company's compliance team size and AML/CFT resource should be proportionate to its client book
Red Flags in Management Company Selection
Walk away from a management company that:
-
Quotes prices significantly below market: Annual management fees below $1,500/year for a GBC structure signal either inadequate service or undisclosed charges. Proper GBC administration — FSC returns, MRA filings, statutory registers, board meeting support — has a real cost.
-
Cannot provide a physical Mauritius office address: A management company operating without a physical presence in Mauritius is likely a shell itself. You need a real on-the-ground team that can appear before the FSC if required.
-
Refuses to provide its FSC licence number for independent verification: Any legitimate management company will provide this without hesitation. Reluctance signals the licence may be suspended, restricted, or non-existent.
-
Recommends nominee directors without explaining substance requirements: Pushing nominee director services without a clear conversation about what genuine substance requires — and what nominee directors alone cannot achieve — indicates the management company is selling convenience rather than compliance.
-
Has no direct banking relationships with Mauritius banks: Your account opening timeline depends on the management company's relationships. A firm that "works with all banks" but has no specific contact at MCB or AfrAsia is not a banking introducer — it is a document forwarder.
-
Promises unrealistic timelines: A GBC set up in "one week" or bank account opened in "10 days" is not a realistic promise. FSC review alone takes 1–2 weeks minimum. Pressure-selling fast timelines usually conceals a willingness to cut compliance corners.
-
Is vague about its beneficial ownership and internal governance: A management company that cannot clearly explain who owns and operates it, and what compliance oversight structures it has internally, is a regulatory liability for your structure.
Compliance Calendar: GBC vs AC
Missing a filing deadline in Mauritius is not just a late fee — it triggers an FSC compliance review, can result in licence suspension, and in serious cases leads to winding-up proceedings. Building the compliance calendar into your operational rhythm from day one is not optional.
Annual Filing Deadlines & Penalties
| Obligation | GBC | AC | Deadline | Penalty for Non-Compliance |
|---|---|---|---|---|
| Annual Return (ROC/CBRD) | Required | Required | Within 28 days of the company's annual meeting date | Late filing fees under Companies Act 2001; escalating to ROC prosecution for persistent failure |
| Tax Return (MRA) | Required | Required | Within 6 months of financial year end | Surcharge of 5% per month on underpaid tax (MRA); interest charges |
| Audited Financial Statements | Mandatory (IFRS) | Not required | Submitted with MRA tax return | MRA may disallow deductions; FSC may initiate review |
| FSC Annual Return | Required | Required | By June 30 each year (standard) | FSC administrative penalties; licence suspension for persistent failure |
| FSC Annual Compliance Statement | Required | Required (simplified) | Submitted with FSC Annual Return | FSC may conduct on-site inspection; escalation to licence suspension |
| Economic Substance Reporting | Required | Not applicable | Submitted with FSC Annual Return | Failure to comply with FSC substance obligations = licence review |
| MRA Advance Payment System (APS) | Required if tax liability exceeds threshold | Not applicable | Quarterly installments | MRA interest on underpayment |
The FSC's penalty framework is graduated: administrative penalties, formal warnings, licence conditions, licence suspension, and in the most serious cases, licence revocation. The FSC has demonstrated willingness to use its supervisory powers — treatment of non-compliance as a minor administrative matter is a serious mistake.
Tax Return, Audit & FSC Returns
GBC audit requirement:
All GBCs must prepare audited financial statements in accordance with International Financial Reporting Standards (IFRS). The audit must be conducted by a qualified external auditor — a Big Four firm (Deloitte, KPMG, PwC, EY — all have Mauritius offices), a mid-tier international firm with a Mauritius presence, or a reputable local firm with ICAM membership (Institute of Chartered Accountants of Mauritius).
The audit report must be submitted to the MRA with the annual tax return and to the FSC as part of the annual compliance package. Budget $1,500–$4,000 per year for GBC audit depending on complexity and the auditing firm engaged.
AC exemption from audit:
ACs are not required to prepare audited financial statements. However, the AC must still file an annual tax return with the MRA and maintain proper accounting records. The absence of an audit obligation does not mean the absence of a tax obligation — the MRA can and does assess ACs for tax liabilities arising from activities conducted in Mauritius.
FSC annual compliance statement:
The FSC requires both GBCs and ACs to file an annual compliance statement confirming that the company has complied with all applicable FSC requirements during the year. For GBCs, this includes confirming substance conditions have been met — number of resident directors, board meetings held in Mauritius, principal bank account maintained, accounting records kept at registered office.
The management company typically prepares and files the FSC annual return and compliance statement on your behalf as part of the annual compliance service. Confirming this is included in your management company engagement letter — and that you receive a copy of all FSC submissions — is a basic governance discipline.
OECD Pillar Two / Global Minimum Tax:
For large multinational groups with consolidated annual revenues of EUR 750 million or more, OECD Pillar Two / the Global Minimum Tax (15% minimum effective rate) applies to the group as a whole. A Mauritius GBC within a EUR 750M+ group may be subject to Top-Up Tax to bring its effective rate to 15% — the 3% partial exemption rate would be insufficient for Pillar Two purposes. Mauritius has enacted domestic legislation to implement Pillar Two. For groups below the EUR 750M threshold, Pillar Two does not directly affect the GBC's tax position.

Frequently Asked Questions
1. What is a Global Business Company (GBC) in Mauritius?
A GBC is a Mauritius tax-resident company licensed by the Financial Services Commission under the Financial Services Act 2007. It is designed for businesses conducting activities primarily outside Mauritius and can access the country's 45+ Double Taxation Avoidance Agreements. GBCs must be administered by an FSC-licensed Management Company, must maintain at least 2 Mauritius-resident directors, and must satisfy economic substance requirements to access the 80% partial exemption on specified foreign-source income. The GBC replaced the previous GBC1 category following the 2019 Finance Act reforms.
2. What is the difference between a GBC and an Authorised Company (AC)?
The primary difference is tax residency. A GBC is Mauritius tax-resident, pays 15% CIT (effective approximately 3% with the partial exemption), and can access DTAs. An AC is non-resident for Mauritius tax purposes, cannot access DTAs, and is simpler and cheaper to maintain — but your home country tax obligations apply in full to the AC's income, and no Mauritius tax protection is available. GBCs require 2 Mauritius-resident directors and an annual IFRS audit; ACs are more flexible on both counts. Choose a GBC when treaty access and Mauritius tax residency are operationally necessary; choose an AC when they are not.
3. What is the effective tax rate for a Mauritius GBC?
The headline rate is 15%, but the 80% partial exemption on specified foreign-source income reduces the effective rate to approximately 3% — assuming the company meets substance requirements. The exemption applies to qualifying foreign-source dividends, interest, royalties, and certain other income categories. Domestic-source income and income not meeting the exemption criteria are taxed at the full 15% rate. You cannot simultaneously claim the partial exemption and a foreign tax credit on the same income stream — your tax advisor must model which treatment is optimal for each income category.
4. How much does it cost to set up a Mauritius GBC?
GBC formation typically costs $3,500–$6,500 including FSC application fee, management company setup, registered office (Year 1), 2 resident directors (Year 1), company secretary, KYC/AML processing, and government registration with the Corporate and Business Registration Department. Annual maintenance runs $4,000–$8,000 depending on substance level, plus economic substance costs of $6,000–$25,000 depending on the nature of your GBC's activities. AC setup costs $2,500–$4,000 with $2,000–$3,500 in annual maintenance and no additional substance cost obligation.
5. Can a foreigner own 100% of a Mauritius GBC?
Yes. Both GBCs and ACs permit 100% foreign ownership with no local shareholder requirements. However, a GBC requires at least 2 directors who are Mauritius residents — these can be professional nominee directors provided through your management company's director pool. The nominee directors must exercise genuine oversight responsibilities and not simply rubber-stamp decisions made elsewhere, which is both a legal requirement and a practical necessity for the company to pass FSC and MRA substance scrutiny.
6. How long does it take to open a bank account for a Mauritius company?
Bank account opening typically takes 4–8 weeks after company incorporation, with complex profiles extending to 10–14 weeks. MCB, AfrAsia Bank, and SBM each have different processing timelines and risk appetites. The timeline depends heavily on the quality of your KYC documentation, the coherence of your business plan, your source of funds narrative, and whether your business profile aligns with the bank's risk tolerance. Expect at least one round of follow-up information requests from the bank's compliance team — building this into your timeline planning is realistic, not pessimistic.
7. Do I need to visit Mauritius to form a company or open a bank account?
Company formation through the management company can be completed entirely remotely — no physical presence in Mauritius is required for incorporation. However, some banks may request an in-person interview or video call for KYC purposes. MCB has been known to require an in-person meeting for higher-risk profiles; AfrAsia and SBM are generally more flexible on remote account opening, particularly where the management company or banking introducer vouches for the applicant. If visiting Mauritius is logistically feasible, it meaningfully accelerates the banking timeline.
8. What are the economic substance requirements for a Mauritius GBC?
A GBC must conduct its core income-generating activities in Mauritius, employ a reasonable number of qualified persons proportionate to its activities, incur proportionate operational expenditure in Mauritius, be directed and managed from Mauritius (with board meetings held in Mauritius with resident directors physically present), maintain its principal bank account with a Bank of Mauritius-licensed institution, keep accounting records at its Mauritius registered office, and have at least 2 Mauritius-resident directors. The FSC assesses substance on a case-by-case basis considering the nature, scale, and complexity of the GBC's specific activities — there is no fixed minimum employee headcount, but the substance must be genuine and proportionate.
9. Can a Mauritius GBC do business in Mauritius itself?
A GBC is primarily designed for business conducted outside Mauritius and can conduct incidental activities in Mauritius necessary for its operations. It cannot actively trade in the Mauritius domestic market — doing so without appropriate domestic licences violates the conditions of its Global Business Licence. If your primary intended market is Mauritius, a domestic company under the Companies Act 2001 is the appropriate vehicle, though this structure does not access the partial exemption regime and is taxed differently from a GBC.
10. What changed for the Mauritius GBC regime in recent years?
The 2019 Finance Act eliminated the previous GBC1/GBC2 structure, consolidating into a single GBC category with mandatory economic substance requirements. The 80% partial exemption replaced the previous deemed foreign tax credit system, which had been flagged by the EU and OECD as potentially harmful because it did not require genuine substance. Mauritius has since aligned with OECD BEPS minimum standards through the Multilateral Instrument, incorporating PPT/LOB provisions into its DTAs. The India–Mauritius DTAA Protocol (effective April 2017) gave India taxing rights over capital gains from Indian company shares acquired after April 1, 2017 — this remains the most significant structural change for India-facing Mauritius structures. More recently, Mauritius's implementation of OECD Pillar Two legislation affects GBCs within EUR 750M+ multinational groups, requiring analysis of top-up tax obligations.
