Mauritius Company Formation: A Complete Guide

A practical guide to Mauritius company formation: the GBC and Authorised Company, tax and treaty position, substance, banking and who it suits.

Mauritius has built one of the most credible international financial centres in the Indian Ocean. Politically stable, English- and French-speaking, with a hybrid common-law and civil-law system and a deep treaty network, it has long been the gateway of choice for investment into Africa and India. For fund managers, holding structures and operating businesses with an African or Asian footprint, Mauritius company formation is frequently the right answer.

It is also a jurisdiction that has reformed substantially. After scrutiny from the OECD and the European Union, and a temporary period on international grey lists, Mauritius overhauled its tax and substance rules. The old deemed-credit shortcuts are gone; the modern regime rewards genuine substance and penalises shells. Understanding that shift is essential to using the jurisdiction well, because the structures that worked a decade ago can now actively fail.

Approached correctly, Mauritius offers something rare: a low-friction, treaty-rich platform that is also broadly accepted by counterparties, regulators and banks across Africa and Asia. Approached lazily, it delivers cost and compliance without the benefits.

This guide covers the principal entity types, the tax and treaty position, substance and banking realities, and the client profile Mauritius genuinely suits.

Entity Types and What They Are For

The domestic vehicle is the ordinary company under the Companies Act, used for businesses trading within Mauritius. For international clients, two forms matter most.

The Global Business Company (GBC) is a Mauritius-resident company holding a Global Business Licence from the Financial Services Commission. It is tax-resident in Mauritius, can access the treaty network, and must satisfy substance requirements. It is the vehicle of choice for funds, holding companies and structures that want treaty benefits and a respected resident status.

The Authorised Company is treated as non-resident for tax, with its place of effective management outside Mauritius. It does not benefit from the treaty network and is taxed where it is genuinely managed. It suits trading or holding activity that does not need Mauritian treaty access and is managed elsewhere.

Choosing between them is not cosmetic. The GBC buys treaty access and resident standing at the price of real substance and Mauritian tax; the Authorised Company is lighter but treaty-disqualified. The right choice flows from whether you actually need the treaties.

The Tax Position

A GBC is, in principle, subject to Mauritian corporate income tax at the standard rate, but a partial exemption regime can exempt a portion of certain qualifying income (such as foreign dividends and interest) where the company meets the prescribed substance conditions. The effective rate on qualifying, well-substanced income can therefore be materially below the headline rate. We deliberately avoid quoting a single effective percentage, because the outcome depends on the income type, the exemption conditions and the company's substance, and the rules are periodically revised.

The key change from the old regime is that benefits are now conditional on substance, not automatic. The discredited deemed foreign tax credit has been abolished. There is generally no capital gains tax, and Mauritius does not impose withholding tax on dividends paid to non-residents, which supports its use as a holding location.

Authorised Companies are not Mauritian tax-resident and are taxed according to where they are managed and where their income arises. They cannot invoke Mauritius's treaties.

Substance Expectations and the Treaty Network

Mauritius's value proposition for inbound investment rests on its treaty and investment-protection network, historically prominent for India and across the African continent. But treaty access is now firmly gated by substance and by anti-abuse rules.

For a GBC, substance means real activity in Mauritius: a Mauritian-resident management presence, qualified employees or appropriate outsourcing, expenditure proportionate to the activity, and core income-generating activities conducted in or from Mauritius. The Financial Services Commission expects these conditions to be met and monitored.

Equally important, treaty partners apply their own anti-treaty-shopping defences, including the principal-purpose test introduced through the BEPS multilateral instrument. A Mauritius company inserted purely to capture a treaty rate, with no commercial substance, is vulnerable to having benefits denied at source. Modern Mauritius structuring therefore starts from genuine substance, not from the treaty table.

Banking Access

Mauritius has a developed banking sector accustomed to international business, which makes banking more accessible than in many smaller offshore centres, though standards are rigorous.

Expect comprehensive due diligence: certified corporate documents, beneficial ownership and source-of-funds evidence, a clear business rationale, and information on counterparties and expected flows. Licensed management companies, which administer GBCs, typically facilitate introductions and the account-opening process, and their involvement smooths the path considerably.

Banks favour structures with genuine substance and a coherent commercial narrative tied to investment into Africa, India or Asia. Pure conduit shells face friction. Where helpful, we arrange banking that complements the Mauritius entity rather than relying on a single relationship.

Compliance and Ongoing Obligations

A Mauritius GBC is a regulated, administered vehicle. It must be administered by a licensed management company, maintain a registered office, keep proper accounting records, file audited financial statements, and submit annual tax returns. The Financial Services Commission supervises licensees, and substance conditions must be satisfied and evidenced on an ongoing basis, not merely at formation.

Mauritius maintains beneficial ownership records and participates in international information exchange, including the Common Reporting Standard. The compliance load is real but predictable, and the involvement of a competent management company makes it manageable. Authorised Companies are lighter to administer but still require a registered agent and ongoing filings.

The recurring theme is that Mauritius now expects to see a properly run, substanced company. That is a feature, not a bug: it is precisely what makes the jurisdiction durable.

Who Mauritius Suits

Mauritius is an excellent fit for funds and fund managers targeting Africa and Asia, for holding companies that genuinely need treaty access and resident standing, and for international groups willing to put real substance on the ground in a stable, well-regulated centre. Its no-capital-gains, no-outbound-dividend-withholding profile supports holding and investment use.

It is a weak fit for anyone wanting a cheap, substance-free conduit purely to strip a treaty rate, or a secrecy vehicle. The post-reform regime and treaty anti-abuse rules defeat those uses.

As always, suitability turns on your residency, your investment geography and your willingness to build genuine substance.

How HPT Helps

We advise on whether a GBC or an Authorised Company fits your objectives, coordinate the management company and licensing, structure substance so that treaty access is defensible, and arrange banking and ongoing administration. Where Mauritius forms part of a wider holding, fund or investment structure, we integrate it with your other entities and your personal residency so the design holds together under scrutiny.

If Africa- or Asia-focused structuring is on your agenda, we would welcome the conversation.
