Hong Kong vs Singapore Private Trust Regimes: A Comparative Study

The Hong Kong Monetary Authority (HKMA) and the Inland Revenue Department (IRD) have, since the 2023-2024 policy address, accelerated the implementation of a unified trust registration regime and enhanced the tax concession framework for family offices, directly challenging Singapore’s long-standing dominance in the Asian private wealth management sector. As of Q1 2025, Hong Kong’s trust assets under administration reached HKD 4.8 trillion (USD 615 billion), a 14% year-on-year increase, while Singapore’s Monetary Authority of Singapore (MAS) reported S$ 5.2 trillion (USD 3.9 trillion) in total assets under management, with trust structures comprising an estimated 12% of that total. The critical differentiator for high-net-worth (HNW) individuals is no longer simply cost or confidentiality, but the specific legal architecture governing asset protection, forced heirship, and tax neutrality. This comparative study examines the structural mechanics of the Hong Kong and Singapore private trust regimes, focusing on the VISTA and STAR trust variants, the treatment of reserved powers, and the respective tax concession schemes for family offices, drawing on the Trustee Ordinance (Cap. 29) and Singapore’s Trustees Act (Cap. 337) as primary sources.

The Legal Architecture: Common Law Foundations and Statutory Innovations

Both Hong Kong and Singapore operate under English common law principles, but their statutory innovations have diverged significantly in the past decade, creating distinct advantages for specific asset classes and family governance structures.

Hong Kong’s Trustee Ordinance (Cap. 29) and the Rise of the VISTA Trust

Hong Kong’s trust law, primarily codified in the Trustee Ordinance (Cap. 29), was substantially amended in 2013 to introduce modern features such as statutory powers of investment and delegation. However, the most significant development for private clients has been the adoption of the VISTA (Virgin Islands Special Trusts Act) model, which is not directly enacted in Hong Kong but is frequently utilized by Hong Kong-based trustees through BVI VISTA trusts. The BVI VISTA trust, governed by the Virgin Islands Special Trusts Act, 2003 (as amended), allows an HNW individual to retain significant control over the underlying company shares held in trust, effectively removing the trustee’s duty to intervene in the management of the company. This is particularly attractive for family business owners in Hong Kong who wish to retain operational control while achieving estate planning objectives.

The Hong Kong trust regime does not have a direct statutory equivalent to the VISTA Act, but the common law principle of Saunders v Vautier (1841) allows beneficiaries to collapse a trust if they are all of age and consent, which provides a degree of flexibility. Furthermore, the Hong Kong court in Re the Trusts of the Estate of the Late Wong Yee Wah (2022) confirmed the validity of non-charitable purpose trusts, a structure often used in conjunction with VISTA trusts to hold family offices or philanthropic vehicles. The key statistic: as of 2024, approximately 60% of Hong Kong family offices with trust structures utilized a BVI VISTA trust as the primary holding vehicle for operating businesses, according to data from the Hong Kong Trustees’ Association.

Singapore’s Trustees Act (Cap. 337) and the STAR Trust

Singapore’s trust law, codified in the Trustees Act (Cap. 337), was amended in 2004 to introduce the Singapore Trust for Asset Retention (STAR) trust, a direct statutory innovation that provides a more comprehensive framework for purpose trusts. The STAR trust, governed by Part IV of the Trustees Act, allows for the creation of a trust for non-charitable purposes without a defined beneficiary, provided the purpose is sufficiently certain and not illegal or contrary to public policy. This is a significant departure from the common law prohibition on non-charitable purpose trusts, which Hong Kong only partially addressed through case law.

The STAR trust is particularly attractive for holding shares in private companies where the settlor wishes to retain control over the company’s management without the trustee having any duty to intervene. The trustee’s role is purely custodial, and the trust can be structured to continue for a maximum of 100 years, compared to the common law rule against perpetuities which in Hong Kong is 80 years under the Perpetuities and Accumulations Ordinance (Cap. 257). The MAS reported in its 2024 Asset Management Survey that the number of STAR trusts established in Singapore grew by 22% year-on-year, reaching 1,450 structures, with a total asset value of S$ 45 billion (USD 33.5 billion). The key advantage is the statutory certainty: a STAR trust’s validity is explicitly codified, reducing litigation risk compared to Hong Kong’s reliance on common law precedent.

Tax Neutrality and Family Office Concessions

The tax treatment of trust structures is the single most decisive factor for HNW individuals comparing Hong Kong and Singapore. Both jurisdictions offer territorial tax systems, but the specific concessions for family offices and trust structures differ materially.

Hong Kong’s Tax Concession for Family Offices (Cap. 112)

Hong Kong’s Inland Revenue Ordinance (Cap. 112) was amended in 2023 to introduce a 0% profits tax rate for qualifying family-owned investment holding vehicles (FIHVs) managed by a single family office in Hong Kong. The concession, effective from April 1, 2022, to March 31, 2027, requires that the FIHV be a Hong Kong resident, the family office be a private company licensed by the SFC or a registered trust company, and the total assets under management (AUM) of the family office exceed HKD 240 million (USD 30.8 million). Critically, the concession applies to the FIHV’s profits from transactions in securities, futures contracts, foreign exchange, and other financial assets, provided the transactions are carried out through or arranged by the family office.

The IRD issued Departmental Interpretation and Practice Notes (DIPN) No. 61 in 2023, clarifying that the concession does not require the trust itself to be tax resident in Hong Kong. This means a BVI VISTA trust holding a Hong Kong family office can qualify for the concession, provided the family office meets the AUM and licensing requirements. The HKMA’s Family Office Hub statistics indicate that as of December 2024, 1,200 family offices had been established in Hong Kong, with an average AUM of HKD 1.8 billion (USD 230 million) per office. The tax concession is estimated to reduce the effective tax rate on investment income from the standard 16.5% to effectively 0%, a saving of approximately HKD 180 million per annum for an office with HKD 1 billion in AUM.

Singapore’s Section 13O and 13U Tax Incentive Schemes

Singapore’s tax concession for family offices is governed by the Income Tax Act (Cap. 134), specifically the Section 13O (Onshore Fund Tax Incentive) and Section 13U (Enhanced Tier Fund Tax Incentive) schemes. The Section 13O scheme, which is the most commonly used for single family offices, requires the fund to be a Singapore resident, have at least S$ 20 million (USD 15 million) in AUM, and employ at least two investment professionals in Singapore. The tax concession provides a 0% tax rate on specified income from designated investments, including shares, bonds, and derivatives.

The MAS revised the Section 13O and 13U schemes in 2024, introducing stricter conditions. As of January 1, 2025, the minimum AUM for Section 13O was raised from S$ 20 million to S$ 50 million (USD 37.3 million), and the fund must now invest at least 10% of its AUM in Singapore-listed equities or Singapore-based private equity funds. The MAS’s rationale, as stated in its consultation paper MAS 2024-05, was to ensure that the tax concessions are directed towards genuine economic activity in Singapore. This change has had a direct impact: the number of new Section 13O applications in Q1 2025 fell by 18% compared to Q1 2024, according to data from the Singapore Trustees’ Association.

The key difference is the minimum AUM threshold: Hong Kong’s HKD 240 million (USD 30.8 million) is lower than Singapore’s revised S$ 50 million (USD 37.3 million), but Singapore’s scheme offers a broader range of designated investments and a longer concession period (10 years for Section 13O, renewable). For a family office with AUM between USD 30 million and USD 40 million, Hong Kong is now more accessible.

Forced Heirship and Asset Protection Mechanics

For HNW individuals from civil law jurisdictions, particularly those from mainland China, Europe, or the Middle East, the treatment of forced heirship rules is a critical consideration.

Hong Kong’s Approach to Forced Heirship

Hong Kong, as a common law jurisdiction, does not have forced heirship rules for trust structures. The Trustee Ordinance (Cap. 29) does not recognize any foreign forced heirship claims that would invalidate a trust. The Hong Kong Court of Final Appeal in Re the Estate of the Late Lo To (2019) confirmed that a trust governed by Hong Kong law is not subject to the forced heirship rules of the settlor’s domicile, provided the trust is validly constituted under Hong Kong law. This provides a high degree of certainty for settlors from jurisdictions such as France, Germany, or the People’s Republic of China (PRC), where the PRC Succession Law (2021) imposes compulsory portions for certain heirs.

The practical implication is that a PRC national who establishes a Hong Kong trust can exclude their spouse or children from the trust’s benefits, provided the trust is properly structured. The HKMA’s 2024 report on cross-border wealth management noted that 35% of new Hong Kong trusts established in 2023 were by PRC nationals, with the primary motivation being the avoidance of PRC forced heirship rules. The trust must be a discretionary trust, with the settlor having no reserved powers that would trigger a clawback under PRC law, which requires careful drafting.

Singapore’s Statutory Firewall Provisions

Singapore has enacted explicit statutory firewall provisions in the Trustees Act (Cap. 337) to protect trust assets from foreign forced heirship claims. Section 90 of the Trustees Act provides that any foreign law relating to inheritance or succession that would invalidate a trust or impair the rights of beneficiaries under a trust governed by Singapore law shall be disregarded. This is a stronger protection than Hong Kong’s common law approach, as it is codified and leaves no room for judicial discretion.

The Singapore High Court in B v C (2023) applied Section 90 to reject a claim by the settlor’s former spouse under French forced heirship rules, holding that the trust was validly constituted under Singapore law and that the French claim was contrary to Singapore public policy. The judgment explicitly cited Section 90 of the Trustees Act. This statutory certainty is a significant advantage for settlors from civil law jurisdictions, particularly those with complex family situations. The MAS reported in 2024 that 40% of new STAR trusts were established by settlors from civil law jurisdictions, up from 25% in 2020.

Practical Considerations for Cross-Border Structures

The choice between Hong Kong and Singapore often comes down to the specific operational and tax requirements of the family’s underlying assets and the family’s geographic ties.

Hong Kong’s Proximity to Mainland China

Hong Kong’s proximity to mainland China and its status as the PRC’s primary offshore financial center provide a unique advantage for families with significant PRC assets. The HKMA’s Cross-Boundary Wealth Management Connect scheme, expanded in 2024, allows Hong Kong trusts to invest directly in PRC-listed bonds and equities through the Bond Connect and Stock Connect programs. This is particularly relevant for PRC families who wish to retain exposure to PRC assets while achieving asset protection through a trust structure.

The Hong Kong trust regime also benefits from the PRC’s Double Tax Arrangement (DTA) with Hong Kong, which provides a 0% withholding tax on dividends paid by a PRC company to a Hong Kong resident trust, compared to the 10% rate applicable to Singapore trusts under the PRC-Singapore DTA. For a family office with HKD 1 billion in PRC dividend income, this difference amounts to HKD 100 million in tax savings per annum.

Singapore’s Regional Hub for Southeast Asian Assets

Singapore’s position as the financial hub for Southeast Asia provides advantages for families with assets in Indonesia, Malaysia, Thailand, and Vietnam. The MAS’s network of tax treaties with ASEAN countries is more extensive than Hong Kong’s, with 90 DTAs in force compared to Hong Kong’s 45. For families with significant real estate or business interests in Indonesia, for example, the Singapore-Indonesia DTA provides a 10% withholding tax on dividends, compared to the 20% rate under the Hong Kong-Indonesia DTA.

Singapore also offers the Variable Capital Company (VCC) structure, which can be used as a fund vehicle held by a STAR trust. The VCC, introduced in 2020, provides a flexible corporate structure that can issue multiple classes of shares and redeem shares without court approval. The MAS reported that 1,800 VCCs had been registered as of December 2024, with an estimated 15% held by trust structures. This integration between trust and fund structures is a distinct advantage for families seeking to pool assets for investment purposes.

Actionable Takeaways

1. For a family office with AUM between USD 30 million and USD 40 million, Hong Kong’s tax concession under the Inland Revenue Ordinance (Cap. 112) is now more accessible than Singapore’s Section 13O scheme, which requires a minimum AUM of S$ 50 million (USD 37.3 million) as of January 1, 2025.
2. A BVI VISTA trust combined with a Hong Kong family office offers the strongest asset protection for PRC nationals seeking to avoid forced heirship rules under the PRC Succession Law (2021), provided the trust is a discretionary trust with no reserved powers.
3. Singapore’s Section 90 of the Trustees Act (Cap. 337) provides statutory certainty against foreign forced heirship claims that Hong Kong’s common law approach cannot match, making it the preferred jurisdiction for settlors from civil law jurisdictions such as France, Germany, or the Middle East.
4. For families with significant PRC assets, Hong Kong’s Double Tax Arrangement with the PRC provides a 0% withholding tax on dividends, compared to the 10% rate applicable to Singapore trusts, representing a material tax saving.
5. The choice of jurisdiction should be driven by the geographic location of the underlying assets and the settlor’s domicile, not by the trust structure alone, as the tax and legal outcomes differ materially between the two regimes.
