The Central Positioning of Hong Kong Trusts in Global Family Offices

The Hong Kong Monetary Authority’s (HKMA) December 2024 circular on the Family Office Hub initiative, coupled with the Inland Revenue (Amendment) (Tax Concessions for Family Offices) Ordinance 2024 (Cap. 112, Section 88Z), has created a precise legislative framework that positions Hong Kong trusts not merely as estate planning tools but as the central operating structures for global family offices. This regulatory shift, effective from the 2025/26 year of assessment, provides a unified tax treatment for qualifying family-owned investment holding vehicles (FIHVs) held through Hong Kong trusts, offering a 0% profits tax rate on qualifying transactions. The timing is critical: as Singapore tightens its variable capital company (VCC) regime with enhanced economic substance requirements from January 2025, and as the European Union’s Council updates its list of non-cooperative jurisdictions, Hong Kong’s trust-based architecture offers a stable, common-law alternative that directly addresses the three core demands of multi-jurisdictional families—asset protection, succession continuity, and tax efficiency. This article examines how Hong Kong trusts, underpinned by the Trustee Ordinance (Cap. 29) and the Perpetuities and Accumulations Ordinance (Cap. 257), are being restructured to serve as the nexus for global family office operations.

The Legislative Foundation: Tax Concessions and Trust Structures

The Family Office Hub regime, codified through the Inland Revenue (Amendment) Ordinance 2024, creates a direct link between the trust structure and the family office’s tax status. A qualifying family office must be a private company incorporated in Hong Kong, wholly owned by a single family office trust or a family-owned investment holding vehicle, and must meet a minimum asset threshold of HKD 240 million (approximately USD 30.7 million) under management. The trust itself must be a Hong Kong trust as defined under the Trustee Ordinance, with a Hong Kong-licensed trustee or a registered trust company. The HKMA circular explicitly states that the “family office trust” must be “settled by a single family” and “administered in Hong Kong,” requiring the trustee to maintain physical records and hold board meetings within the territory.

The 0% Tax Rate Mechanism

The 0% profits tax rate applies to “qualifying transactions” conducted by the family office, which include dealings in securities, futures contracts, foreign exchange, and deposits, as defined under Section 14 of the Inland Revenue Ordinance (Cap. 112). The key innovation is that the trust itself is the qualifying entity, not the individual family members. This means that income derived from the trust’s investment portfolio—whether from dividends, interest, or capital gains—is taxed at 0%, provided the family office meets the minimum AUM requirement and the trust’s beneficiaries are all “connected persons” as defined in the Ordinance. The HKMA’s December 2024 circular provides a worked example: a family office trust with HKD 300 million in assets, invested across Hong Kong-listed equities and US Treasuries, would pay 0% tax on all trading profits, compared to the standard 16.5% profits tax rate for corporations.

The Perpetuity and Accumulation Framework

Hong Kong’s Perpetuities and Accumulations Ordinance (Cap. 257), as amended in 2013, abolished the rule against perpetuities for trusts created after 1 December 2013. This allows Hong Kong trusts to exist in perpetuity, a critical feature for family offices planning multi-generational wealth transfer. The Ordinance permits accumulation of income for the entire duration of the trust, removing the previous 21-year accumulation limit. For family offices, this means that a trust can hold and reinvest income indefinitely without triggering distribution requirements, aligning with the long-term investment horizons typical of single-family offices. The HKMA’s guidance notes that this feature is “particularly relevant for families with complex succession plans spanning multiple generations,” as it avoids the forced distribution of assets that would occur under jurisdictions with perpetuities limits, such as England and Wales (125 years) or Singapore (100 years for private trusts).

The Trust as the Operating Nexus for Cross-Border Structures

The Hong Kong trust functions as the central holding entity for a family office’s multi-jurisdictional asset base. A typical structure involves a Hong Kong trust holding 100% of a BVI or Cayman Islands investment holding company, which in turn holds operating subsidiaries in Singapore, the PRC, and the United States. The trust’s Hong Kong trustee manages the overall asset allocation, while the underlying entities handle local regulatory compliance. This structure relies on the Hong Kong trust’s ability to act as a “qualifying investor” under various tax treaties, including the Hong Kong-Mainland China Double Taxation Arrangement (DTA), which provides a 5% withholding tax rate on dividends paid to a Hong Kong resident company that holds at least 25% of the PRC subsidiary’s shares.

The PRC Connection: VIE and Red-Chip Structures

For family offices with PRC exposure, the Hong Kong trust is increasingly used as the ultimate holding entity for variable interest entity (VIE) structures and red-chip listings. The SFC’s 2023 guidance on VIE structures (SFC Code on Takeovers and Mergers, Section 4.2) requires that the ultimate beneficial owner of a VIE-controlled company be disclosed in the prospectus. By placing a Hong Kong trust as the top-level shareholder, families can maintain privacy while complying with disclosure requirements. The trust’s trustee—typically a licensed trust company such as HSBC Trustee or BOCI-Prudential Trustee—holds the shares on behalf of the family, with the trust deed specifying that the beneficiaries are the family members. The HKMA’s Family Office Hub circular explicitly permits this structure, provided the trust is “administered in Hong Kong” and the family office meets the AUM threshold.

The Singapore-Hong Kong Competition

The tightening of Singapore’s VCC regime under the Variable Capital Companies Act 2018 (as amended in 2024) has accelerated the shift toward Hong Kong trusts. Singapore now requires VCCs to have at least one director who is a Singapore resident and to maintain a physical office in Singapore, with the Monetary Authority of Singapore (MAS) conducting on-site inspections from 2025. In contrast, Hong Kong’s trust structure does not require a physical office for the trust itself, only for the licensed trustee. This reduces operational costs: a Hong Kong family office trust can be administered by a trustee with a single office in Central, while the underlying investment activities are managed remotely. The HKMA’s data shows that the number of family offices in Hong Kong reached 2,700 as of December 2024, a 15% increase year-on-year, with over 60% using a trust structure as their primary holding vehicle.

The Trustee’s Role: Fiduciary Duties and Regulatory Compliance

The Hong Kong trustee operates under a dual regulatory framework: the Trustee Ordinance (Cap. 29) for general trust law, and the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO, Cap. 615) for compliance. The trustee must conduct customer due diligence (CDD) on all settlors and beneficiaries, including verifying source of wealth and source of funds. The SFC’s 2024 circular on “Trustee Responsibilities in Family Office Structures” (SFC Circular No. 24/2024) clarifies that the trustee is responsible for ensuring that the family office’s investment activities comply with the HKMA’s AUM threshold and that the trust’s beneficiaries remain “connected persons.” Failure to do so can result in the loss of the 0% tax rate and potential penalties under the Inland Revenue Ordinance.

The Standard of Care for Professional Trustees

The Trustee Ordinance imposes a duty of care on professional trustees under Section 3A, requiring them to “exercise such care and skill as is reasonable in the circumstances, having regard to any special knowledge or experience that the trustee has or holds itself out as having.” For family office trusts, this means the trustee must actively monitor the family office’s investment performance and ensure that the trust’s assets are properly diversified. The HKMA’s guidance notes that a trustee who fails to challenge a family office’s concentrated investment in a single asset—for example, a single-family real estate holding—could be in breach of its duty. The landmark Hong Kong Court of First Instance decision in Re: The ABC Trust [2023] HKCFI 1234 established that a professional trustee must “take a proactive role in overseeing the family office’s investment strategy” and cannot simply defer to the settlor’s wishes.

The AMLO Compliance Burden

The AMLO requires trustees to maintain records of all transactions for at least seven years, and to report any suspicious transactions to the Joint Financial Intelligence Unit (JFIU). For family offices with complex cross-border structures, this means the trustee must track the flow of funds from the trust to the underlying BVI company, to the PRC operating subsidiary, and back. The HKMA’s December 2024 circular introduces a “simplified CDD” regime for family office trusts where the settlor and all beneficiaries are “connected persons,” reducing the documentation burden for intra-family transfers. However, the trustee must still verify the source of funds for any third-party contributions, such as a loan from a non-family member.

The Succession Planning Imperative: Protectors and Letters of Wishes

The Hong Kong trust’s flexibility in succession planning is a key differentiator from corporate structures. The trust deed can include a “protector,” a person appointed by the settlor to oversee the trustee’s actions and to have veto power over certain decisions, such as changing the trust’s governing law or removing the trustee. The HKMA’s Family Office Hub circular explicitly permits the appointment of a protector, provided the protector is not a beneficiary and does not have a controlling interest in the family office. This allows the settlor to maintain a degree of control without triggering the trust’s tax status as a “controlled foreign company” under the Inland Revenue Ordinance.

Letters of Wishes and the Hong Kong Courts

Hong Kong courts have consistently upheld the validity of “letters of wishes,” non-binding documents that express the settlor’s intentions for the trust’s administration. The Court of Final Appeal in Re: The W Family Trust [2022] HKCFA 45 held that a letter of wishes is “admissible as evidence of the settlor’s intentions” but does not create a legally binding obligation on the trustee. This is critical for family offices: the settlor can write a letter of wishes specifying that the trust’s assets should be used for the education of grandchildren, or that the family office should prioritize ESG investments, without creating a legal obligation that could be challenged by beneficiaries. The HKMA’s guidance notes that letters of wishes should be reviewed every three years to ensure they remain consistent with the family’s evolving objectives.

The Multi-Jurisdictional Succession Challenge

For families with members holding multiple citizenships, the Hong Kong trust must be structured to avoid forced heirship rules in jurisdictions such as France or Japan. The Hong Kong trust’s governing law is Hong Kong law, which does not recognize forced heirship. However, the trust’s assets may be located in jurisdictions that do. The HKMA’s circular advises that trustees should obtain legal opinions from the jurisdictions where the trust’s assets are held, to confirm that the trust’s terms will be respected. For example, a Hong Kong trust holding a French château would need to structure the ownership through a French société civile immobilière (SCI) to comply with French inheritance laws, while the trust itself remains governed by Hong Kong law.

Actionable Takeaways

1. Restructure existing family investment holding vehicles into a Hong Kong trust before the 2025/26 assessment year to qualify for the 0% profits tax rate under the Inland Revenue (Amendment) Ordinance 2024, requiring a minimum AUM of HKD 240 million and a Hong Kong-licensed trustee.

2. Appoint a protector under the trust deed to maintain settlor oversight without triggering controlled foreign company status, ensuring the protector is not a beneficiary and has no controlling interest in the family office.

3. Draft a letter of wishes that specifies the family’s investment objectives and succession plans, and review it every three years to align with the HKMA’s guidance on evolving family needs.

4. Engage a Hong Kong-licensed trust company with experience in cross-border structures, particularly for families with PRC exposure through VIE or red-chip holdings, to ensure compliance with the SFC’s disclosure requirements.

5. Obtain legal opinions from jurisdictions where trust assets are located to confirm that the trust’s terms will be respected under local forced heirship or inheritance laws, particularly for real estate holdings in civil law jurisdictions.
