The Mauritius GBC in 2026: A Guide to Tax, Treaties & Substance
For routing investment into Africa and Asia, few structures match the Mauritius Global Business Company. It pairs an effective tax rate near 3% with one of the most useful treaty networks in the emerging world — but only if you meet the substance rules. Here is how the GBC actually works in 2026, and when it is the right vehicle.
Mauritius GBC — key facts, 2026
Why Mauritius — the gateway case
Mauritius earns its place not by being the cheapest, but by being the most useful low-tax base for one job: moving capital into Africa and Asia through a respected, treaty-rich hub.
- The treaty network. Over 45 double-tax agreements — spanning India, much of Africa, and parts of Asia and Europe — cut withholding taxes on cross-border dividends, interest and royalties. This is the GBC’s defining advantage.
- A ~3% effective rate. A 15% headline, reduced to roughly 3% on qualifying foreign-source income, sits among the lowest genuinely treaty-accessible rates anywhere.
- No CGT, no dividend withholding. Mauritius levies no capital gains tax on the disposal of securities and no withholding tax on dividends paid out — ideal for a holding layer.
- Credibility. Mauritius is on the EU whitelist, OECD-compliant and FATF-aligned, and its GBCs are accepted by international banks and institutional investors — a long way from the grey-list years.
The natural comparison is with other low-tax holding hubs; see our ranking of the best holding-company jurisdictions and, for the Asian gateways specifically, Singapore vs Hong Kong vs Dubai. Mauritius wins where the destination is Africa or India.
GBC or Authorised Company — which vehicle
Mauritius offers two global-business vehicles, and the choice turns on a single question: do you need treaty access?
| Feature | Global Business Company (GBC) | Authorised Company (AC) |
|---|---|---|
| Tax residence | Mauritius tax resident | Non-resident (managed from abroad) |
| Treaty access (45 concluded DTAs) | Yes — full network | No |
| Tax | 15% headline; ~3% effective on qualifying foreign income | Not taxed in Mauritius |
| Substance in Mauritius | Required — CIGA, resident directors, staff | Not required; central management abroad |
| Licence / regulator | FSC — Global Business Licence | FSC — Authorised Company |
| Best for | Treaty-based holding, funds, regional HQ | Trading or holding where treaties aren’t needed |
The GBC is licensed by the Financial Services Commission under the Financial Services Act 2007, is a Mauritius tax resident, and can therefore claim treaty benefits — the right choice for treaty-based holding, fund and headquarters structures. The Authorised Company, which replaced the old GBC2 in 2019, is treated as non-resident and sits outside the treaty network; it suits trading or asset-holding where treaty access is irrelevant. Both are administered through a licensed management company.
The 2026 tax picture — how you reach 3%
The headline rate is 15%. The number that matters is the effective one, and how you get there.
- 15% to ~3%. A GBC is taxed at 15% on worldwide income, but an 80% partial exemption applies to specified foreign-source income — foreign dividends, interest, royalties and certain securities gains — bringing the effective rate on that income to around 3%. Malaysia reaches a similar effective rate by a different route: Labuan company formation is taxed under LBATA at a headline 3% on audited trading profits, with no partial-exemption mechanism to maintain.
- Conditional on substance. The exemption is tied to economic-substance conditions, not to where the owner lives — which is precisely why it is OECD- and EU-compliant. Fail the substance test and the full 15% applies, potentially retroactively.
- No CGT, no dividend WHT. No capital gains tax on disposals of securities, and no withholding on dividends paid to shareholders, resident or not.
- Pillar Two. From 2025 Mauritius applies a 15% Qualified Domestic Minimum Top-up Tax to in-scope multinational groups (broadly, those above €750M revenue), so the largest groups top up to 15% — the ~3% rate remains available to ordinary companies below that threshold.
The classic illustration: an investor holds Indian or African portfolio companies through a GBC; the treaty cuts dividend withholding at source, and the 80% exemption then taxes that income at roughly 3% in Mauritius — far below holding directly or through a non-treaty jurisdiction. See the wider framework on our Mauritius company formation page.
Substance — the condition for everything
Substance is not paperwork; it is the price of the tax rate and the treaties. Get it right and the GBC works; get it wrong and you lose both.
To qualify for the partial exemption and to hold up as a treaty resident, a GBC must satisfy the FSC’s substance requirements:
- Core Income-Generating Activities (CIGA) carried out in or from Mauritius;
- Adequate qualified people employed, directly or indirectly, to conduct that activity;
- Minimum expenditure in Mauritius proportionate to the level of activity;
- Local governance — in practice at least two Mauritius-resident directors, board meetings held in Mauritius, and accounting records kept locally; and
- A licensed management company administering the entity and acting as the conduit to the FSC and the Registrar.
Annual audited accounts must be filed with the FSC within six months of year-end, with tax returns to the Mauritius Revenue Authority. Inadequate substance is the single most common reason a GBC structure fails on review — so it is engineered in from day one, not bolted on later.
Setting up — process & pitfalls
Incorporation itself is quick; doing it so the structure actually holds is the skill.
The typical sequence
- Appoint a management company. An FSC-licensed management company is mandatory and files the application; the choice of provider matters for banking and ongoing service.
- Incorporate and licence. Form the company under the Companies Act 2001 and apply for the Global Business Licence from the FSC, with the business plan, due diligence and fit-and-proper documentation.
- Build substance. Appoint the resident directors, arrange local management and the office/people proportionate to the activity, and open the Mauritius bank account.
- Operate and report. Hold board meetings in Mauritius, keep records locally, file audited accounts within six months of year-end and the annual tax return.
Mistakes founders make
- Choosing a GBC when an AC would do — or the reverse. If you do not need treaties, the GBC’s substance burden is wasted cost; if you do, an AC quietly fails.
- Treating substance as optional. Two resident directors on paper with no real activity will not survive scrutiny — and the exemption is withdrawn.
- Assuming old treaty benefits still apply. The India treaty’s capital-gains advantage was curtailed years ago; the dividend and interest benefits remain, but the structure must be built for today’s rules.
- Underestimating banking and timelines. Bank onboarding, not incorporation, is usually the long pole — begin it alongside the licence.
What changed in 2026
Two things moved this year that most Mauritius write-ups have not caught up with, and both bear directly on whether a GBC is the right vehicle.
FSC fees rose on 1 July 2026. The Financial Services (Consolidated Licensing and Fees) (Amendment) Rules 2026, Government Notice No. 119 of 2026, set the Global Business Licence annual fee at USD 2,600 with a USD 600 processing fee. An Authorised Company now carries USD 1,400 annually plus USD 600 processing and a USD 65 annual registration fee to the Registrar. The increase was proportionally larger for Authorised Companies, which had been sitting on a lower base. A useful detail nobody publishes: the first annual fee is pro-rated by the quarter in which the licence is granted, so a GBC licensed in the April to June quarter pays USD 650 rather than USD 2,600. If your incorporation date is flexible, that timing is worth real money. The full schedule is set out on our Mauritius company formation page.
The India treaty is being tightened again. The 2024 Protocol, signed on 7 March 2024, replaces the treaty preamble and inserts a Principal Purpose Test allowing either state to deny benefits where obtaining them was one of the principal purposes of an arrangement. It is not yet in force — the Mauritian Cabinet agreed to ratify it on 17 July 2026, and entry into force requires both states to exchange ratification instruments. When it does take effect it applies without regard to the taxable years concerned, meaning there is no transition period and no grandfathering of existing arrangements. Anyone relying on the India corridor should be substance-ready before that exchange happens, not after. We set out the full timeline on our Mauritius holding company page.
And substance is being enforced, not just written down. In the Godolphin Ltd matter the Mauritius Revenue Authority disallowed the 80% partial exemption on a holding and lending structure, finding the substance conditions unmet — specifically the requirement to employ, directly or indirectly, a reasonable number of suitably qualified persons to conduct the core income generating activity. Engaging a management company, appointing resident directors and running an investment committee was argued as compliance and was not accepted as sufficient on its own. The exemption is a conditional relief, not a rate.
Frequently asked questions
The questions investors ask most about the Mauritius GBC.
What is a Mauritius GBC?
A Global Business Company is a Mauritius company licensed by the Financial Services Commission (FSC) under the Financial Services Act 2007 and incorporated under the Companies Act 2001. It is a Mauritius tax resident, which lets it access the country’s 45 double-tax treaties, and it benefits from the 80% partial exemption that can bring the effective tax rate on qualifying foreign income to about 3%, subject to substance.
How is a Mauritius GBC taxed in 2026?
The headline corporate rate is 15%, but an 80% partial exemption applies to specified foreign-source income — foreign dividends, interest, royalties and certain securities gains — reducing the effective rate on that income to roughly 3%, provided substance conditions are met. There is no capital gains tax on securities and no withholding tax on dividends paid out. Large multinational groups (above ~€750M revenue) top up to 15% under the new Pillar Two domestic minimum tax.
What is the difference between a GBC and an Authorised Company?
A GBC is a Mauritius tax resident with treaty access and the partial-exemption regime, but it must meet substance requirements. An Authorised Company (which replaced the old GBC2 in 2019) is treated as non-resident, has no treaty access, and is used for trading or holding where treaties are not needed. The deciding question is whether you need the treaty network.
What substance does a Mauritius GBC need?
To qualify for the partial exemption and treaty residence, a GBC must carry out its core income-generating activities in or from Mauritius, employ an adequate number of qualified people, incur proportionate local expenditure, and have genuine local governance — in practice at least two resident directors, board meetings in Mauritius, and local records. A licensed management company administers the entity.
What is the Mauritius GBC used for?
Most commonly as a treaty-based holding company for investment into Africa, India and Asia; as a fund or fund-management vehicle (Mauritius is a major fund domicile); as a regional headquarters; and for treasury, IP or financing structures. The unifying theme is using the treaty network and the low effective rate to hold or route cross-border income efficiently.
How many tax treaties does Mauritius have?
Mauritius has concluded more than 45 double-taxation agreements, with partners across Africa, Asia, Europe and the Middle East. The African network in particular — alongside the long-standing India treaty — is the main reason investors route into those markets through a Mauritius GBC rather than directly.
How long does it take to set up a Mauritius GBC?
In straightforward cases, incorporation and FSC licensing can be completed within a few business days once the management company has complete documentation and due diligence. Building genuine substance and opening banking take longer and should run in parallel; a realistic timeline to a fully operational, bank-equipped structure is several weeks.
Is Mauritius still a credible jurisdiction?
Yes. Mauritius was removed from the EU and FATF grey lists in 2021–22 after substantial reforms, is OECD-compliant, and its GBCs are widely accepted by international banks and institutional investors. The trade-off for that credibility is the substance regime — which is exactly what makes the structure robust today.
What are the Mauritius FSC fees in 2026?
Under Government Notice No. 119 of 2026, in force from 1 July 2026, a Global Business Licence carries a USD 600 processing fee and a USD 2,600 annual fee. An Authorised Company carries USD 600 processing and USD 1,400 annually, plus a USD 65 annual registration fee to the Registrar of Companies. The first annual fee is pro-rated by the quarter in which the licence is granted, so a GBC licensed between April and June pays USD 650 rather than USD 2,600.
Does the Mauritius-India treaty still work in 2026?
Partly, and it is tightening. The 2016 Protocol ended the capital gains exemption for Indian shares acquired on or after 1 April 2017, with earlier acquisitions grandfathered. The 2024 Protocol inserts a Principal Purpose Test and is not yet in force, though the Mauritian Cabinet agreed to ratify it on 17 July 2026. When it takes effect it applies without regard to the taxable years concerned, so there is no transition period. Dividends, interest and treaty protection continue to matter; what has gone is treating a Tax Residence Certificate as a complete answer.
Has the MRA ever refused the 80% partial exemption?
Yes. In the Godolphin Ltd matter a Global Business Licence company claimed the exemption on interest from loans to a South African subsidiary and the Mauritius Revenue Authority disallowed it, finding the substance conditions unmet on the requirement to employ a reasonable number of suitably qualified persons to conduct the core income generating activity. Having a management company, resident directors and an investment committee was not accepted as sufficient on its own.
What does a Mauritius GBC cost?
Sovera charges from USD 3,500 all-in for Year 1, with the CBRD incorporation, the FSC Global Business Licence, the licensed management company, registered office, company secretary and two Mauritius-resident directors included, and government fees at cost. Annual renewal is from USD 3,550 all-in, being the USD 2,600 FSC fee at cost plus a USD 950 Sovera fee. Corporate bank account opening is USD 1,500.
Can a Mauritius GBC be used as a holding company?
Yes, and that is its most common use. A GBC holding shares in operating companies abroad can claim treaty relief on dividends, interest and royalties flowing up, pays no Mauritius capital gains tax on exit, and distributes to non-resident shareholders with no withholding. It is the dominant structure for Africa-focused private equity. The conditions are the same as for any GBC: real substance in Mauritius and a Tax Residence Certificate the counterparty jurisdiction will accept.
Set up your Mauritius GBC with substance engineered in
A GBC is only as good as its substance and its treaty positioning. Sovera Global selects the management company, secures the FSC licence, puts genuine substance in place and opens the banking — so the ~3% rate and the treaty access actually stand, advising from Dubai with English- and Russian-speaking principals.
