Mauritius Beneficial Ownership in 2026: The Global Business Company and the Closed Register

Mauritius is easy to file under "offshore" and misread as a result. It is not a high-volume shell factory; it is a treaty conduit, built to route institutional capital into India and Africa through companies that must be genuinely managed and controlled on the island. That model — treaty access in exchange for real substance — shapes its entire approach to beneficial ownership: a 20% threshold below the global norm, a register held by the state but closed to the public, and a licensed profession standing behind every structure. Understanding the conduit is the key to verifying anything that runs through it.

01The conduit, not the shell

The defining fact about Mauritius is what its companies are for. The flagship vehicle, the Global Business Company, exists to be tax-resident in Mauritius so it can use the island's network of double-tax treaties — and in return it must demonstrate that it is actually run from Mauritius. That is a fundamentally different proposition from a jurisdiction that sells anonymity, and it changes what a verifier is looking at: not a nominee-wrapped blank, but a substance-backed entity whose ownership is documented, filed, and — crucially — kept out of public view.

So the Mauritius question is not "is this a secrecy vehicle" — the substance regime pushes against that — but "the register exists and the data is disciplined, so how do I reach the natural person when it is closed to me." The answer runs through the same three things every time: the 20% test, the licensed management company, and the treaty structure above.

02The scale and the model

The global business sector is central to the Mauritian economy, not a sideline. Global Business Companies held around US$741 billion in total assets in 2022, and the sector contributed roughly 8.4% of GDP. Mauritius became the leading conduit for institutional investment into Africa and, historically, the single largest source of foreign direct investment into India — a position built entirely on its treaty network and its reputation as a credible, regulated base rather than a flag of convenience.

That reputation rests on a licensed intermediary. Every Global Business Company must be administered by a licensed management company — a regulated corporate-services firm that handles incorporation, compliance, and the collection of ownership information. The management company is the Mauritian equivalent of the registered agent elsewhere in this corpus, but with a heavier remit: it is the entity the regulator holds responsible for knowing who is behind the structures it administers.

03The treaty that built it — and 2016

No treaty mattered more than the one with India. For three decades the Mauritius–India agreement exempted capital gains on Indian shares from tax, which made routing investment into India through a Mauritius company overwhelmingly attractive — and made Mauritius the top source of recorded FDI into India. That is the "conduit" in its purest form.

It changed in 2016. A protocol amended the treaty so that capital gains on Indian investments made through Mauritius companies after 1 April 2017 became taxable in India, with earlier investments grandfathered. The pure tax arbitrage narrowed sharply, and with it the incentive to use Mauritius as a paper pass-through. The jurisdiction's response was to lean into substance and to pivot toward Africa, where its treaty and investment-protection network across the continent still offers genuine structuring value. For a verifier, the lesson is that a modern Mauritius structure is less likely to be an empty conduit than its reputation suggests — but the ownership behind it still has to be resolved.

04Off the lists, fast

Mauritius spent under two years on the international watchlists and treated exit as a national priority. Its rehabilitation is one of the quicker ones in this corpus, and beneficial-ownership transparency was an explicit part of it.

05The framework: the Companies Act and the register

Beneficial ownership in Mauritius sits primarily in the Companies Act 2001, refined by successive Finance Acts — the Finance (Miscellaneous Provisions) Act 2019, and most recently the Finance Act 2025, which elevated the regime from an administrative duty to a compliance pillar. Section 2 defines a beneficial owner as the natural person who ultimately owns or controls a company, or on whose behalf a transaction is conducted, with control arising through voting rights, the power to appoint or remove directors, or ownership of shares in a prescribed percentage.

Every company must keep a register of beneficial owners, retain the information for seven years, and file it with the Registrar of Companies — the Corporate and Business Registration Department (CBRD) — within 14 days of any entry or change. For entities in the global business sector, the beneficial-ownership information also reaches the Financial Services Commission through the licensing process. Both custodians hold the data; neither publishes it. Trusts and foundations fall within the same regime, resolving through control rather than shareholding, as in Liechtenstein.

06Who counts as a beneficial owner — the 20% rule

The threshold is the fact most commonly reported wrongly, and Mauritius is a clean example of why reading the statute matters: the prescribed threshold is 20%, not 25%. Numerous compliance summaries state 25% by analogy to the FATF norm; the Mauritian regulations do not.

The Mauritius beneficial-owner test

A natural person captured by any of these

1

Ownership — 20%A natural person holding, directly or through a nominee, not less than 20% of the aggregate voting power — or, for a global business company, 20% of the distributable profits.

2

Board controlThe ability to appoint or remove directors, or to control the company through voting rights.

3

Ultimate control by other meansAny natural person who ultimately owns or controls the company, or on whose behalf a transaction is conducted.

4

Senior officials (fallback)Where no beneficial owner is identified, the senior managing officials of the company.

07What the register records — and the filing clock

The Finance Act 2025 sharpened the documentation. A company must now obtain, maintain, and file a written declaration of beneficial ownership from each beneficial owner, and appoint an authorised resident officer responsible for the information. The obligation is continuing: a beneficial owner must notify the company of any change — a shift in shareholding, a new controller, or the death of a UBO.

What the beneficial-ownership register holds

Particulars recorded and filed under the Companies Act

Field	Recorded?	Note
Full name and residential address	Yes	Of the beneficial owner or ultimate beneficial owner
Passport or National ID number	Yes	Identifying document of the natural person
Nominee details	Yes	Where a nominee holds, the nominee and the UBO behind are both recorded
Nature and extent of interest	Yes	The shareholding or control that meets the 20% test
Written declaration	Since 2025	A signed declaration from the beneficial owner, retained by the company
Retention	7 years	Records kept for seven years; changes filed within 14 days

08Access: held by the state, closed to you

Mauritius files beneficial ownership with the state but keeps it out of public reach. The register is a supervisory and law-enforcement resource, not a transparency tool for counterparties.

Who can reach Mauritius beneficial-ownership data

Access under the Companies Act framework

Who	Access	Basis
Registrar (CBRD) & FSC	Custodians	Hold the filed register; the FSC for global business licensees
Competent authorities	On lawful basis	Disclosure permitted for investigation or inquiry, and to law enforcement
The management company	Own clients	Collects and holds the underlying information and declarations
Obliged entities & the public	No access	Beneficial-ownership information is not publicly accessible

09The management company: gatekeeper and filer

The licensed management company is the load-bearing element of Mauritian compliance, and understanding its role is central to any verification. By law, a Global Business Company must be administered by one: it cannot be self-incorporated or run from a laptop abroad. The management company performs the customer due diligence, collects the beneficial-ownership declarations, files with the CBRD and FSC, and provides the resident directors and registered office that the substance rules require.

For a verifier, this concentrates the answer in a known, regulated place. Every Mauritius GBC has a management company that has, by obligation, identified its beneficial owners to a standard the FSC supervises. The data is not visible to you, but it exists, it is held by an accountable licensee, and it is a specific, answerable thing to request through the customer — a stronger position than a jurisdiction where no such intermediary is required.

10GBC versus Authorised Company

The single most important distinction in Mauritian structuring — and one that changes both the tax treatment and the transparency picture — is between the two main global vehicles, which replaced the old GBC1 and GBC2 categories from 2019.

Global Business Company vs Authorised Company

Two vehicles, two very different profiles

Feature	Global Business Company	Authorised Company
Tax residence	Resident	Non-resident
Treaty access	Yes — the whole point	None
Managed and controlled	In Mauritius	Outside Mauritius
Regulator	FSC-licensed	FSC-registered, lighter touch
Replaced	GBC1	GBC2

11The funds sector: where the UBO analysis changes

Mauritius is, above all, a funds domicile. More than a thousand investment funds — predominantly private equity, but also hedge, real-estate and debt funds — are licensed by the FSC, many of them structured as Global Business Companies. A fund is the single most common Mauritius structure a verifier will meet, and it is the one where the ownership question works differently.

Funds come in two families under the Securities (Collective Investment Schemes and Closed-end Funds) Regulations 2008: the open-ended collective investment scheme (CIS), which must redeem investors on request, and the closed-end fund (CEF). Either can be constituted as a company, a limited partnership, a unit trust, a protected cell company or a variable capital company — so the legal wrapper varies, but the beneficial-ownership logic is consistent.

Where the UBO sits in a Mauritius fund

Why the ownership test rarely resolves at 20% — and what to look at instead

1

InvestorsUsually too dispersed for any one to cross the 20% ownership threshold — so ownership alone rarely identifies a UBO.

2

Any 20%+ investorWhere a single investor does exceed 20%, they are a beneficial owner — but an additional one, not the whole answer.

3

Manager or general partnerThe party that controls the fund — the analysis usually resolves here, on the control limb.

4

Senior managing officialsThe fallback where neither ownership nor a controller is identified.

12Trusts and foundations

Above and alongside the corporate layer sits the private wealth-structuring layer, and it follows the control-not-shares logic familiar from every trust and foundation regime.

A Mauritius trust, under the Trusts Act 2001, is an arrangement in which trustees hold assets for beneficiaries. It has no legal personality, requires no registration or incorporation, and where it is a fund or financial trust must be authorised by the FSC; a non-resident trust sits outside Mauritius tax. Because there is no corporate filing and no register to search, a trust is among the most private structures in the jurisdiction — the beneficial-ownership answer of settlor, trustee, protector and beneficiaries comes only from the trust deed and the administering licensee.

A Mauritius foundation, under the Foundations Act 2012, is the civil-law counterpart: unlike a trust it does have legal personality, established by a founder, managed by a council, for named beneficiaries or a purpose. The question is again who controls and benefits, not who holds shares. Both trusts and foundations fall within the beneficial-ownership regime, yet neither surfaces its parties on any public file.

13Substance: the price of the treaty

The reason a Global Business Company is more transparent than a classic shell is the substance regime. To be tax-resident and claim treaty benefits, a GBC must be managed and controlled in Mauritius: it must have at least two resident directors, maintain a registered office and local administration, keep its accounting records and file audited financial statements with the FSC, and demonstrate core income-generating activity on the island. The FSC assesses these requirements actively, and a Tax Residence Certificate — the document that unlocks treaty relief — depends on meeting them.

This matters for beneficial ownership in a subtle way. A jurisdiction that requires resident directors, audited accounts and real administration produces a paper trail that a pure secrecy vehicle does not. The owner is still not on a public file — but the structure around them is documented, supervised, and anchored to identifiable, accountable local actors. Substance is the mechanism that turned Mauritius from a grey-listed conduit into a jurisdiction that clears international review.

14Information exchange: FATCA and CRS

The same transparency logic that closed the register to the public opened it to other states. Mauritius participates fully in automatic exchange of financial-account information under both the US FATCA framework — via a Model 1 intergovernmental agreement signed in 2014 — and the OECD Common Reporting Standard. Every Mauritius fund and financial institution is a reporting institution: it must register with the Mauritius Revenue Authority, obtain a global intermediary identification number, run due diligence and self-certification on its account holders, and report annually.

The pattern is the one that runs through every closed-register jurisdiction in this corpus. A Mauritius GBC's ownership is invisible to a foreign bank onboarding it, yet its financial-account data may already be flowing automatically to that bank's home tax authority through the CRS. Closed to you is not closed to everyone — and for a treaty jurisdiction whose credibility depends on exchange, that channel is central rather than incidental.

15The registry: what is public

The public layer is the CBRD's company registry, searchable online. It confirms the corporate shell and its officers — but not its owners.

What the CBRD registry returns

The public company search, and where it stops

Data point	Public?	Note
Company name, number, status	Yes	Searchable on the CBRD online platform
Company type and incorporation date	Yes	Domestic company, GBC, Authorised Company and others
Directors	Often	Typically retrievable via a company search or filed documents
Shareholders	Sometimes	Legal shareholders may appear; they are frequently not the owners
Beneficial owners	No	Filed with the state but not publicly accessible

The registry is operated online by the Corporate and Business Registration Department, which lets you search by company name or number and returns the entity's existence, type and status, with directors typically retrievable from the record. Confirm current search fees and any account requirement at the CBRD before relying on it — and note that the beneficial-ownership register sitting behind the public record is not part of the searchable interface.

16Penalties and enforcement

The Companies Act attaches real financial consequences to getting beneficial ownership wrong, and it reaches the individuals responsible, not just the entity.

Under section 91(3D) of the Companies Act, failure to comply with the beneficial-ownership requirements can draw a penalty of MUR 300,000 on the company, with each director separately exposed to the same amount. Personal director liability — rather than a penalty absorbed by a corporate shell — is the design choice that gives the regime teeth, and it aligns the incentives of the resident directors the substance rules require.

17Multi-layer structures: Mauritius in the chain

A Mauritius entity is, by its nature, usually a middle layer — a treaty-resident holding company between an investor and an operating business in India or Africa. That is the structure a verifier must unwind.

Where a Mauritius ownership chain resolves

A typical conduit structure, investment to ultimate individual

1

The operating assetAn operating company or investment in India or Africa, held below the Mauritius vehicle.

2

The Mauritius GBCThe treaty-resident holding company — CBRD-registered, FSC-licensed, management-company administered.

3

The investor or fund aboveA fund, holding company or family structure in another jurisdiction — often where open data lives.

4

Natural-person UBOThe controller or beneficiary — resolved via disclosure, the management company and the layer above.

18A worked example

Take the structure Mauritius is built for. A private-equity fund invests into an African operating company through a Mauritius Global Business Company. The GBC is administered by a licensed management company, which provides two resident directors and the registered office. The GBC's registered shareholder is the fund vehicle, domiciled elsewhere.

Run the playbook. A CBRD search confirms the GBC exists, its status, and its management-company-supplied directors — none of whom is the owner. The registered shareholder is the fund, not a natural person, so the 20% test does not resolve at the Mauritius level; it points upward. The beneficial-ownership register, held by the company and filed to the state, names the individuals behind the fund who meet the 20% threshold — but it is closed to you.

Resolution runs two ways at once. Downward, the substance trail — resident directors, audited accounts, the management company's KYC — confirms the GBC is real and identifies the accountable local actors. Upward, the fund or holding vehicle above the GBC is where the natural person is found, in whatever jurisdiction it sits. The Mauritius layer proves the structure is substance-backed; the individual is resolved through the management company's disclosure and the chain above.

19Common failure modes

20How to verify a Mauritius UBO: workflow

1. Confirm the entity. Search the CBRD registry for name, number, type and status. Identify whether it is a GBC, an Authorised Company or a domestic company.
2. Read the structure. A GBC is a treaty-resident middle layer; expect the owner to sit in a fund or holding vehicle above it, not in Mauritius itself.
3. Apply the 20% test. Run ownership and voting power at twenty percent, then board control, then ultimate control by other means. Do not import a 25% threshold.
4. Identify the management company. It administers the GBC, holds the beneficial-ownership declarations and KYC, and is the route to disclosure.
5. Request the declaration. Ask the customer for the written beneficial-ownership declaration and, where a nominee holds, the ultimate beneficial owner behind it.
6. Follow the chain up. Resolve the fund or holding layer above the GBC in a jurisdiction whose register is reachable, and carry the chain to the natural person.
7. Screen and evidence. Screen the resolved individual against sanctions, PEP and adverse-media sources, and keep an auditable trail.

21Practical takeaways

Mauritius rewards a verifier who reads it correctly. It is not a secrecy shell but a substance-backed conduit — its companies are genuinely administered, its threshold sits below the global norm at 20%, and its rehabilitation was built partly on giving authorities access to ownership data. What it does not do is open that data to you. Build the workflow around the management company, the 20% test and the treaty layer above — and resolve the owner from the chain, not the closed register beneath it.
