How to Open a Mauritius GBC Company — Global Business Corporation Guide (2026)

What Makes Mauritius GBC Unique

The Mauritius GBC is not an offshore shell — it is a tax-resident company, recognised as tax-resident by Mauritius and by treaty partner countries. This treaty residency is its core value: 46 tax treaties including India (8% WHT on dividends), South Africa (5%), Kenya (5%), UAE (0%), Singapore (5%), and more.

The combination: 3% effective Mauritius corporate tax + treaty-reduced withholding taxes on income from subsidiary companies = highly efficient holding/intermediary structure for sub-Saharan Africa and Indian subcontinent investments.

The 80% Foreign Tax Credit

Mauritius domestic corporate tax rate: 15%. GBC companies are entitled to a presumptive 80% foreign tax credit — meaning 80% of their 15% liability is credited, resulting in an effective rate of 3% on net income.

This foreign tax credit is presumptive — you don't need to prove you paid 15% in a foreign country to claim it. The credit is given automatically against Mauritius CT liability.

• Example: GBC earns $1,000,000 in income.
• Mauritius CT at 15%: $150,000
• 80% foreign tax credit: $120,000
• Net Mauritius CT payable: $30,000 (3%)

GBC vs Former GBC 1 and GBC 2

Pre-2019, Mauritius had two categories: GBC1 (tax-resident, treaty access) and GBC2 (non-tax-resident, no treaty access, used for pure offshore). Following OECD pressure, the GBC2 category was abolished in 2021. All existing GBC2s were converted to "Authorised Companies" — which are NOT tax-resident and have NO treaty access.

The current GBC (formerly GBC1) is the ONLY Mauritius structure with treaty access. Do not confuse it with Authorised Companies, which are cheaper but treaty-neutral.

Step-by-Step: Forming a Mauritius GBC

• Step 1: Engage a Licensed Management Company
• GBC companies must be administered by a licensed Mauritius Management Company (MC). This is a legal requirement — not optional. The MC:
• Applies for the GBC licence on your behalf
• Provides Mauritius-resident directors (minimum 2, of which majority must be Mauritius residents for substance)
• Prepares company documents
• Files with the Registrar of Companies and FSC (Financial Services Commission)

Licensed management companies include: IQ-EQ Mauritius, Vistra, Apex Group, Intercontinental Trust, Altios International. Cost: $4,000–8,000/year for management services.

• Step 2: Choose Your GBC Licence
• GBC licence issued by the Financial Services Commission (FSC). Application via your Management Company:
• Company name (must end with "GBC" or include "Global Business Corporation")
• Business plan and structure overview
• Beneficial owner KYC (passport, source of funds, corporate structure chart)
• FSC application fee: $1,500–2,500

Processing: 2–6 weeks.

Step 3: Incorporation Simultaneously, incorporate the company with the Registrar of Companies (now via MauCompany online portal). Company constitution (Articles). Standard share capital: $1 or whatever minimum you set.

• Step 4: Substance Requirements
• To access treaty benefits, the GBC must have substance in Mauritius. Minimum:
• 2 Mauritius-resident directors (provided by the Management Company)
• Board meetings in Mauritius (your MC facilitates this — typically quarterly or semi-annual)
• Bank account in Mauritius (MCB, ABC Banking, SBM, BCP Bank)
• Proper accounting records maintained in Mauritius
• Management Company keeping the registered office

This is outsourced substance — the MC provides resident directors who are real people making real decisions (or at least appropriately ratifying them). OECD has scrutinised this — as long as the Mauritius directors genuinely participate in key decisions, this structure is defensible.

• Step 5: Open a Mauritius Bank Account
• MCB (Mauritius Commercial Bank): Largest bank, excellent for international transfers
• SBM (State Bank of Mauritius): Strong Asia-Africa focus
• AfrAsia Bank: Boutique international bank, excellent for sophisticated structures
• ABC Banking: Good for international transactions

Account opening: 2–6 weeks, requires KYC documentation for all beneficial owners.

Treaty Applications: Claiming Reduced Withholding

To claim a reduced withholding tax rate under a Mauritius treaty (e.g., paying dividend from Kenya to Mauritius GBC at 5% vs 15% domestic rate):

1. Obtain a Tax Residence Certificate from MRA (Mauritius Revenue Authority) — free, takes 1–2 weeks. Renewed annually. 2. Submit the certificate to the paying company in the treaty country before the dividend payment. 3. The paying company applies the treaty rate.

Annual tax residence certificate renewal is handled by your Management Company as part of their service.

The Africa Investment Holding Structure in Practice

Typical structure: ``` Founder(s) — personal level ↓ Mauritius GBC (HoldCo) ├── Kenya Operating Company (30% WHT → 5% via treaty) ├── Rwanda Operating Company (15% WHT → 5% via Mauritius-Rwanda DTT) └── Nigeria Operating Company (10% WHT → 7.5% via Mauritius-Nigeria treaty if applicable) ```

Mauritius GBC receives dividends from African subsidiaries at treaty rates. Pays 3% effective CT in Mauritius. Founder receives remaining profits from Mauritius GBC (Mauritius has 0% withholding on dividends to non-residents — no additional withholding layer when distributing to the founder).

FAQs

Is a Mauritius GBC an "offshore" structure? Not technically — it is a Mauritius tax-resident entity, which means it is "onshore" in Mauritius and taxed there. However, the 3% effective rate, the offshore banking orientation, and the historical reputation as an offshore jurisdiction mean many refer to it colloquially as offshore.

Can a sole founder own a Mauritius GBC 100%? Yes — 100% foreign ownership, single shareholder permitted.

Does Mauritius report to other countries' tax authorities? Yes. Mauritius is CRS-compliant and reports financial account information to treaty-partner countries. Your home country tax authority will know about your Mauritius GBC if they request information or if CRS triggers automatic reporting.

What is the difference between a GBC and an Authorised Company? A GBC is Mauritius tax-resident and has treaty access. An Authorised Company is NOT Mauritius tax-resident — it's "deemed non-resident" — has no treaty access, and is cheaper to maintain ($1,000–2,000/year). Authorised Companies are used for simple holding without treaty requirements.
