Mauritius Trust

The Mauritius Trusts Act 2001 replaced the earlier Offshore Trusts Act 1989 and substantially modernised the trust framework in Mauritius. The 2001 Act is the primary statute governing the creation, administration, and enforcement of trusts in Mauritius. It is supplemented by subsequent amendments — including Act No. 22 of 2005 and Act No. 14 of 2007 — and is administered under the oversight of the Financial Services Commission (FSC), the single regulatory authority for Mauritius’s international financial services sector.

Key structural features of the Act include: a managed/custodian trustee split structure (unique among the jurisdictions in this series); the settlor may be a beneficiary but not the sole beneficiary; purpose trusts are expressly permitted with mandatory enforcer appointment; the protector’s role and powers are codified; and trust property may not be immovable property in Mauritius (except for charitable trusts), which is an important practical constraint for real estate structuring. The Hague Convention on Trusts has been ratified by Mauritius. Foreign trusts are recognised. The proper law of the trust can be migrated to another jurisdiction.

Duration: private Mauritius trusts are limited to 99 years. This is an important honest distinction — shorter than Malta’s 125-year cap and significantly shorter than the perpetual duration offered by Cyprus, Guernsey, and the Isle of Man. Purpose trusts and charitable trusts may be established for unlimited duration. The accumulation period for non-charitable trusts is also capped — income accumulation within a Mauritius trust may not exceed 25 years, after which income must be distributed or applied.

One of the most significant changes introduced by the 2001 Act relative to the old Offshore Trusts Act concerns the standard of proof for creditor challenges to trust transfers. The old Act required creditors to prove fraudulent intent beyond reasonable doubt — a high threshold that provided robust protection. The 2001 Act reduced this to the balance of probabilities standard. This is a meaningful step down in creditor protection quality, and it places Mauritius behind Cook Islands, Nevis, and even the old Offshore Trusts Act on this specific dimension. The change should be understood clearly before choosing Mauritius for adversarial creditor protection purposes.

Mauritius’s treaty network is the defining feature that makes it structurally irreplaceable for clients with African or Asian business interests. With 45 concluded bilateral tax treaties — including 18 African countries — Mauritius has treaty coverage in Sub-Saharan Africa that no other offshore trust jurisdiction comes close to matching. Covered African markets include South Africa, Botswana, Lesotho, Madagascar, Mozambique, Rwanda, Senegal, Seychelles, Swaziland, Tunisia, Uganda, and Zimbabwe. Additional African treaties are at various stages of negotiation or ratification.

For fund managers, private equity firms, development finance vehicles, and family offices with significant African investment exposure, Mauritius is not merely a convenient offshore location — it is structurally required by the investment framework. DFIs (development finance institutions), sovereign wealth funds, and institutional investors deploying capital into Sub-Saharan Africa routinely route investments through Mauritius for the treaty efficiency it provides. As of December 2024, 213 licensed management companies operate in Mauritius’s global business sector, demonstrating the depth and maturity of the jurisdiction’s professional services market.

The India connection is the other critical axis. For decades, Mauritius was the dominant route for investment into India — the Mauritius-India DTAA originally exempted capital gains on Indian shares realised by Mauritius residents. This attracted enormous flows of FDI and portfolio investment through Mauritius. The 2016 protocol began to reduce these benefits, and the March 2024 protocol introduced the Principal Purpose Test (PPT) — a requirement that treaty benefits may be denied if a principal purpose of an arrangement was to obtain those benefits, without genuine commercial substance backing the structure.

The 2024 protocol means that Mauritius-India structures now require demonstrable economic substance in Mauritius — genuine management and control, board-level decision-making from Mauritius, and a clear commercial rationale that goes beyond treaty access. This is not the end of the Mauritius-India route; it is the beginning of a more rigorous substance-driven approach. Mauritius remains the most accessible treaty partner for India-bound investment from an offshore base — but structures must be properly substance-backed from day one. We always ensure clients receive specialist tax advice before establishing any Mauritius trust with India treaty implications.

Mauritius trusts provide asset protection through the standard trust mechanism: trust assets do not form part of the settlor’s personal estate; the trustee’s personal creditors cannot access trust property; and in a discretionary trust, no beneficiary has a fixed entitlement that a creditor can attach. The Trusts Act 2001 provides that a trust may be declared void where it is established that the trust was made with the intent to defraud creditors of the settlor at the time the trust property was vested in the trustee.

The Trusts Act 2001 also contains firewall provisions: Mauritian courts will not recognise the validity of any foreign judgment relating to: (a) the personal proprietary consequences of marriage; (b) succession rights; or (c) claims of creditors in an insolvency proceeding — to the extent inconsistent with the Trusts Act. Transfers to a Mauritius trust by non-citizens cannot be set aside, avoided, or declared invalid on the basis that the disposition is in breach of the local law of the settlor’s domicile or nationality in relation to inheritance or succession. This forced heirship firewall is a meaningful practical protection for international clients from civil law countries with forced heirship regimes.

The critical honest point: the Trusts Act 2001 downgraded the creditor standard of proof from the Offshore Trusts Act 1989. The old Act required creditors to prove fraudulent intent beyond reasonable doubt — the same high standard used by the Cook Islands. The 2001 Act reduced this to balance of probabilities — the civil standard used in ordinary litigation. This means a creditor who can show, on the balance of probabilities, that the trust was established with intent to defraud them can have the trust declared void. This is weaker than Cook Islands (beyond reasonable doubt), Nevis (beyond reasonable doubt plus mandatory bond), and the Bahamas (two-year limitation period plus civil standard). There is also no mandatory creditor bond in Mauritius (unlike Nevis).

For clients whose primary objective is adversarial protection against a specific US creditor or government enforcement agency, the Cook Islands Trust is the structurally stronger tool, and we say so directly. Mauritius asset protection works best in the succession planning and estate protection context — preventing forced heirship claims from civil law jurisdictions, protecting against future creditors whose claims arise after the trust is established, and providing privacy from public access to trust information.

Mauritius imposes no capital gains tax. A trust resident in Mauritius is liable to income tax at 15%, but it is entitled to a foreign tax credit on any foreign-source income if it has paid foreign tax on that income — meaning the effective rate can be significantly reduced. Non-resident trusts and non-resident beneficiaries are exempt from Mauritius tax in respect of trust income. Dividends and royalties derived from Mauritius and paid to non-residents are exempt from Mauritius tax. The combination of no capital gains tax, treaty access, and the foreign tax credit mechanism has historically made Mauritius one of the world’s most tax-efficient investment platforms for cross-border structuring.

The 45 concluded bilateral double tax treaties are the primary source of tax efficiency for Mauritius structures. These treaties reduce or eliminate withholding taxes on dividends, interest, and royalties flowing from treaty partner countries through Mauritius. For fund managers deploying capital across multiple African markets, a Mauritius holding structure can materially reduce the overall tax burden on cross-border income through the treaty network. Annual income tax returns must be submitted to the Mauritius Revenue Authority within six months of the financial year end.

Substance requirements are now the central compliance consideration for any Mauritius trust seeking to access treaty benefits. Since 2019, when Mauritius eliminated the Category 2 Global Business Licence and enhanced its AML/CFT framework following international pressure, the FSC expects to see genuine economic substance in the jurisdiction: key decisions must be made in Mauritius; board meetings for underlying GBCs should be held in Mauritius with directors physically present; and the management of the trust and its underlying structures should be genuinely conducted from Mauritius. Structures designed purely to access treaty benefits without genuine Mauritius-based management and control are at risk of having treaty benefits denied under the Principal Purpose Test, which the 2024 India-Mauritius protocol has now formally codified.

This means the cost of maintaining a Mauritius trust structure includes meaningful, ongoing substance — licensed management company fees, qualified directors conducting business in Mauritius, audited accounts, annual returns to the MRA and FSC filings. Clients who want the Mauritius treaty network must genuinely use the Mauritius platform, not just hold the licence. Offshore Broker always ensures clients are fully informed of the substance cost before committing to a Mauritius structure.

Mauritius trusts are used extensively for succession and estate planning — allowing the settlor to direct the distribution of assets to beneficiaries without probate, protecting against forced heirship claims from civil law jurisdictions, and providing for beneficiaries across multiple generations within the 99-year trust duration. The Trusts Act 2001 explicitly provides that where a non-citizen transfers or disposes of assets to a Mauritius trust, that transfer cannot be set aside, avoided, or declared invalid on the basis that it breaches the local law of the settlor’s domicile or nationality in relation to inheritance or succession.

This is a meaningful forced heirship firewall for international clients from France, Spain, Italy, the Middle East, or other civil law jurisdictions where domestic succession law would mandate fixed inheritance shares. The Mauritius trust places those assets outside the jurisdiction of the home country’s succession courts, governed by Mauritius law alone. The settlor may be a beneficiary under the trust — explicitly permitted — allowing the settlor to retain income rights while securing succession planning goals. A Protector may be appointed to supervise the trustee’s administration and exercise veto rights over specified trustee actions.

Duration must be stated explicitly in the trust deed — Mauritius trusts do not default to perpetual but must specify the duration up to the 99-year maximum. For clients requiring multi-generational structures that must outlast 99 years, consideration should be given to whether Mauritius or a perpetual trust jurisdiction (Cyprus, Guernsey, Isle of Man) better serves the objective. Within the 99-year window, Mauritius trusts provide the flexibility of a discretionary structure with wide trustee powers, an active protector role, the managed/custodian trustee split, and the ability to change the proper law of the trust.

The managed/custodian trustee structure is distinctive and useful for estate planning across multiple jurisdictions. The custodian trustee — which may be offshore — holds the trust assets in a segregated manner. The managing trustee in Mauritius handles the day-to-day administration, distribution decisions, and regulatory compliance. This split allows the physical custody of trust assets to remain with an institution in the client’s preferred banking jurisdiction while all trustee management takes place in Mauritius under FSC oversight. For complex international estates with assets in multiple countries, this structure provides practical operational flexibility.

All professional trustees in Mauritius must be licensed by the Financial Services Commission (FSC) — specifically as a management company holding a Global Business Licence or such other authorisation as the FSC prescribes. The FSC is the single regulatory authority for Mauritius’s international financial services sector, covering trust services, fund administration, investment management, global business companies, and related activities. As of December 2024, 213 licensed management companies operate in Mauritius — the largest concentration of licensed trust service providers in any Indian Ocean jurisdiction.

The FSC regulates trustees under a risk-based supervision framework, conducts on-site inspections, issues guidance notes and circulars on compliance requirements, and has enforcement powers including licence suspension, revocation, and financial penalties. The FSC is the Mauritius competent authority for FATCA, CRS, and automatic information exchange, and the island is fully compliant with OECD and FATF standards. Mauritius was placed on the FATF grey list in 2020 — a development that caused some short-term reputational damage — and was removed from the grey list in 2021 following remedial action. This history is worth disclosing honestly: it is part of the Mauritius record, but the jurisdiction’s removal from the grey list and subsequent compliance investments mean it is not a current live concern for well-structured arrangements.

The FSC’s licensing framework for management companies requires that all key persons be fit and proper, that the management company maintain adequate financial resources and professional indemnity, that AML/KYC programmes meet international standards, and that substance requirements are met for structures seeking treaty benefits. The regulatory quality of the FSC is broadly considered adequate for an emerging international financial centre of Mauritius’s size and treaty footprint, though it is not considered to be at the same level as the GFSC (Guernsey), IOMFSA (Isle of Man), or MFSA (Malta) in terms of regulatory depth and international standing.

This regulatory positioning reflects Mauritius’s broader profile in the international financial services market: a genuinely useful and treaty-connected jurisdiction for Africa and Asia-oriented investment structures, with a maturing but still-developing regulatory framework that requires clients and their advisors to apply rigorous due diligence to trustee selection. The 213 licensed management companies range from global professional services firms to smaller boutique operators — quality varies, and Offshore Broker’s direct relationships with reputable FSC-licensed trustees are an important part of the value we provide.

The Mauritius Trust’s primary client is an individual, family, or fund manager with significant African or Asian business interests who needs a treaty-efficient offshore structure with genuine tax and investment planning value in those markets. African entrepreneurs and business owners who have built companies across multiple Sub-Saharan African countries and want a single holding and succession planning structure with treaty access across their portfolio markets; Indian-origin families with business interests across both India and Africa; private equity and venture capital funds deploying capital into African growth markets; and development finance institutions structuring investments through Mauritius for treaty efficiency — these are the core client profiles that Mauritius serves distinctively well.

Mauritius is also used by French-speaking clients from North and West Africa for whom no other trust jurisdiction offers the combination of Francophone legal and cultural familiarity, African treaty access, and a credible offshore regulatory framework. The Indian Ocean geographic position and French legal heritage give Mauritius a connectivity to Francophone Africa that Caribbean and Channel Islands jurisdictions simply cannot match.

What Mauritius is generally not the best choice for: clients whose primary objective is adversarial creditor protection against US judgment creditors (Cook Islands and Nevis are the stronger tools); clients who need perpetual dynasty trusts beyond the 99-year cap (Cyprus, Guernsey, Isle of Man offer perpetual duration); and clients who need the regulatory standing of a GFSC or IOMFSA-regulated trustee for UK or European institutional counterparties.

For clients comparing Mauritius to Hong Kong as an Indian Ocean/Asia gateway: Hong Kong is unmatched for mainland China connectivity, offshore RMB, and the Greater Bay Area framework. Mauritius is the stronger choice for Sub-Saharan Africa coverage and for India-bound investment (notwithstanding the 2024 protocol). Both are useful in a multi-jurisdictional structure for a family or fund with exposure across both Africa and Asia. Offshore Broker is honest about these distinctions at every initial consultation.

Mauritius occupies a position in the trust landscape that is genuinely without equivalent in one specific respect: its treaty network for Sub-Saharan Africa. For clients whose trust structure must interact with African investment markets — through withholding tax reduction, investment promotion agreement protection, or treaty-based certainty on capital gains treatment — no other trust jurisdiction provides the depth of African treaty coverage that Mauritius does. This is a structural advantage that Guernsey, Isle of Man, Cyprus, Malta, Cayman, the Bahamas, and the Cook Islands simply cannot replicate.

The Cook Islands Trust is unambiguously the world’s strongest adversarial creditor protection structure. For clients focused on protecting assets from a US judgment creditor or government enforcement agency, the Cook Islands is our recommendation: beyond-reasonable-doubt burden of proof, one-to-two-year limitation period, and a 40-year track record. The Nevis Trust adds a mandatory $100,000 creditor bond. Mauritius’s creditor standard (balance of probabilities) is explicitly weaker, and the old Offshore Trusts Act’s stronger standard was unfortunately downgraded by the 2001 Act.

Compared to Bahamas: the Bahamas FDA provides a two-year limitation period and civil standard — similar standard of proof to Mauritius but with the benefit of a defined time limit after which creditors are barred. Mauritius does not have a statutory time limit for creditor challenges. On pure creditor protection, the Bahamas is positioned ahead of Mauritius.

Compared to Cyprus and Malta as treaty-connected trust jurisdictions: Cyprus has 65+ treaties and perpetual trust duration; Malta has 70+ treaties and perpetual commercial trusts. Neither has the African treaty footprint of Mauritius, which covers African markets that neither Cyprus nor Malta has agreements with. For clients whose treaty need is African market access, Mauritius is the correct choice; for EU-regulated institutional standing, Cyprus or Malta are preferable. Compared to Guernsey and Isle of Man: both have deeper UK institutional credibility, perpetual duration, stronger firewall legislation, and GFSC/IOMFSA regulation. Neither has African treaty access. For UK-connected families, Guernsey and IoM are the stronger choice; for Africa-connected families, Mauritius is structurally correct. We offer all jurisdictions and give our honest view at every consultation.
