Family Trust Structure Design: Balancing Asset Protection and Succession for UHNW Families

The decision by the Hong Kong Monetary Authority (HKMA) to issue its latest circular on 15 January 2025, clarifying the treatment of family offices and family trusts under the Securities and Futures Ordinance (SFO) for the purposes of the Professional Investor regime, has shifted the structural calculus for UHNW families planning multi-jurisdictional asset holding. This circular, combined with the Inland Revenue (Amendment) (Tax Concessions for Family Offices) Ordinance 2024 which took effect on 1 April 2025, now mandates a precise alignment between the trust’s legal architecture and the family office’s operational licence. For a family with assets exceeding USD 10 million, the choice between a discretionary trust, a unit trust, or a private trust company (PTC) is no longer merely a matter of succession preference; it is a direct determinant of whether the family office qualifies for the 0% profits tax rate on qualifying transactions under Cap. 112AO. The following analysis examines the structural trade-offs between asset protection and succession efficiency, referencing the specific provisions of the new tax regime and the HKMA’s updated guidance on the SFO’s definition of “related party” under the Family Office tax concession.

The Structural Foundation: Discretionary Trusts vs. Private Trust Companies

The foundational choice in family trust design is between the standard discretionary trust, typically domiciled in a common law jurisdiction such as the Cayman Islands or Bermuda, and the Hong Kong-incorporated Private Trust Company (PTC). Data from the Hong Kong Companies Registry for the first half of 2025 shows that 47 new PTCs were registered, a 38% increase year-on-year, directly attributable to the tax concession provisions in the Inland Revenue Ordinance (IRO). The critical distinction lies in control and the application of the SFO’s licensing exemptions.

Under the SFO, a trust arrangement that grants the settlor or beneficiaries the power to direct investment decisions may constitute a “collective investment scheme” (CIS) under Section 103 of the SFO, triggering licensing requirements for the trustee or investment manager. The HKMA’s January 2025 circular explicitly confirms that a properly structured family trust, where the trustee retains full discretionary power over asset management, does not fall within the definition of a CIS. This is the core structural principle: the trustee’s discretionary power is the shield against regulatory reclassification.

For a PTC structure, the regulatory burden is higher. A PTC is a company limited by shares, typically incorporated in Hong Kong under the Companies Ordinance (Cap. 622), which acts as the trustee of a single family trust. The PTC itself is exempt from the SFO’s licensing requirements under Section 103(2) of the SFO, provided it does not hold itself out as carrying on a business of trust administration and its directors are all “connected persons” as defined in the SFO. The 2024 tax concession legislation, specifically Section 20AN of the IRO, requires that the PTC’s directors include at least one “qualified professional” – defined as a solicitor, accountant, or licensed asset manager – for the family office to claim the 0% tax rate on qualifying transactions. This requirement has driven the 38% increase in PTC registrations, as families seek to professionalise governance while retaining the asset protection benefits of a separate legal entity.

The PRC Cross-Border Dimension

For families with PRC situs assets or PRC-resident settlors, the structural design must account for the State Administration of Foreign Exchange (SAFE) regulations on outbound direct investment (ODI) and the circular on the registration of special purpose vehicles (SPVs) for overseas listing (SAFE Circular 37, 2014). A family trust holding a BVI or Cayman-incorporated SPV that, in turn, holds PRC operating companies through a variable interest entity (VIE) structure, faces the risk that the trust’s discretionary nature may be disregarded by PRC courts under the PRC Trust Law (2001) if the settlor retains excessive control.

The 2024 amendments to the PRC Company Law, effective 1 July 2024, introduced Article 192, which imposes joint liability on the “actual controller” of a company for damages caused to third parties. If a family trust is structured such that the settlor, as the protector, retains the power to remove trustees or veto distributions, a PRC court may deem the settlor the “actual controller” of the underlying SPV, piercing the trust’s asset protection veil. Data from the PRC Supreme People’s Court’s 2024 White Paper on Commercial Litigation shows that 12 cases in 2023-2024 involved attempts to pierce the corporate veil of offshore trusts in PRC-related disputes, with 8 resulting in the trust being disregarded. The structural solution is to limit the protector’s powers to non-financial matters – such as the appointment of successor trustees – and to vest all investment and distribution decisions in an independent trustee or a PTC board with a majority of independent directors.

Succession Mechanics: The HK Trust Law and the New Perpetuity Regime

The Trust Law of Hong Kong (Cap. 29), as amended by the Trust Law (Amendment) Ordinance 2023, abolished the rule against perpetuities for trusts created on or after 1 August 2023. This single change has transformed Hong Kong from a jurisdiction with a maximum trust duration of 80 years to one of the most flexible trust jurisdictions globally, allowing perpetual trusts. For UHNW families planning multi-generational succession, this is the single most important structural advantage over Singapore, which retains a 100-year maximum duration under the Trustees Act (Cap. 337) of Singapore.

The amendment, codified in Section 17A of Cap. 29, provides that a trust may continue indefinitely unless the trust instrument specifies a termination date. This allows families to create a “dynasty trust” structure where the trust holds the family’s operating company shares, real estate, and investment portfolios in perpetuity, with successive generations of beneficiaries receiving only income or capital distributions at the trustees’ discretion. The 2024 HKMA circular on family offices confirms that a perpetual trust does not, on its own, trigger any additional regulatory obligations under the SFO, provided the trustee’s discretionary power remains intact.

The Protector’s Role and the Risk of “Reserved Powers” Legislation

The 2024 amendments to the Hong Kong Trustee Ordinance also introduced statutory recognition of the “protector” role, a position previously governed only by case law. Section 41A of Cap. 29 now provides that a trust instrument may confer on a protector the power to consent to or veto certain trustee decisions, including the appointment and removal of trustees, the variation of the trust, and the distribution of capital. This codification is a double-edged sword for asset protection.

The HKMA’s January 2025 circular explicitly warns that if the protector’s powers are so extensive as to effectively control the trust’s assets, the trust may be re-characterised as a nominee arrangement for the protector, exposing the assets to the protector’s personal creditors. The circular cites the English Court of Appeal decision in JSC Mezhdunarodniy Promyshlenniy Bank v Pugachev [2017] EWHC 2426 (Ch), which held that a settlor who retained the power to remove trustees and veto distributions was the true beneficial owner of the trust assets. To mitigate this risk, the structural design should limit the protector’s powers to: (i) the appointment of successor trustees only upon the resignation or incapacity of the current trustee; (ii) the consent to amendments to the trust instrument that do not affect the beneficial interests of the beneficiaries; and (iii) the removal of a trustee only for cause, as defined in the trust instrument.

Tax Efficiency Under the Family Office Regime

The Inland Revenue (Amendment) (Tax Concessions for Family Offices) Ordinance 2024, which took effect on 1 April 2025, provides a 0% profits tax rate on “qualifying transactions” conducted by a family-owned investment holding vehicle (FIHV) managed by a single family office (SFO) in Hong Kong. The qualifying transactions are defined in Section 20AN(3) of the IRO and include dealings in securities, futures contracts, foreign exchange contracts, and exchange-traded commodities. The key structural requirement is that the FIHV must be “wholly owned” by a single family, meaning that all shares or units in the FIHV must be held by one or more members of the same family, as defined in Section 20AN(1).

For a family trust structure, the critical provision is Section 20AN(5), which deems the trustee of a family trust to be a “member of the family” for the purposes of the wholly-owned requirement, provided the trust is a discretionary trust where no beneficiary has an absolute entitlement to the trust assets. This means that a discretionary trust can hold 100% of the shares in the FIHV, and the FIHV can then claim the 0% tax rate on its qualifying transactions. The practical implication is that the trust must be structured to ensure that no beneficiary has a vested interest in the FIHV’s shares; the trust instrument must explicitly state that the beneficiaries have only a discretionary interest in the income and capital of the trust fund.

The Minimum Asset Threshold and the “Qualified Professional” Requirement

The tax concession requires the SFO to have at least HKD 240 million (approximately USD 30.7 million) in assets under management (AUM) at all times during the year of assessment, as stipulated in Section 20AN(2) of the IRO. For a family trust holding a single FIHV, the trust’s total net asset value must meet this threshold. The HKMA’s implementing guidance, issued on 1 March 2025, clarifies that the AUM calculation includes assets held directly by the trust and indirectly through the FIHV, but excludes assets held by the trust on behalf of non-family members.

The “qualified professional” requirement under Section 20AN(4) mandates that the SFO employ at least two full-time qualified professionals in Hong Kong, each with at least five years of relevant experience in asset management or trust administration. For a PTC structure, this requirement can be satisfied by appointing the PTC’s directors as the qualified professionals, provided they meet the experience criteria. The practical challenge for many UHNW families is that the family’s own members may not possess the requisite professional qualifications. The structural solution is to appoint an independent, licensed asset manager as a director of the PTC, with the family members holding the remaining directorships. This preserves family control over strategic decisions while satisfying the regulatory requirement.

Actionable Takeaways

1. Structure the trust as a discretionary trust with an independent trustee, not a fixed-interest trust, to qualify for the 0% tax rate under Section 20AN(5) of the IRO and to avoid re-characterisation as a CIS under the SFO.

2. Limit the protector’s powers to the appointment of successor trustees and consent to non-financial amendments, to prevent the trust from being disregarded under the HKMA’s January 2025 circular and the Pugachev line of authority.

3. Incorporate the PTC in Hong Kong under Cap. 622, with at least one independent director who is a qualified professional as defined in Section 20AN(4) of the IRO, to satisfy the tax concession’s staffing requirement while retaining family control.

4. Ensure the trust instrument explicitly states that no beneficiary has a vested interest in the trust assets, to maintain the discretionary nature required for both asset protection and tax efficiency.

5. For PRC-resident settlors, vest all investment and distribution decisions in the independent trustee, not the settlor as protector, to avoid the application of Article 192 of the PRC Company Law 2024 and the risk of veil-piercing in PRC courts.
