Trust Instruments in Hong Kong Estate Planning

Hong Kong’s trust industry recorded a compound annual growth rate of 8.2% in total trust assets under administration between 2019 and 2023, reaching HKD 4.6 trillion according to the Hong Kong Trustees’ Association’s 2024 industry survey. This expansion is not merely a function of wealth accumulation in Asia. The primary driver is a structural shift in how high-net-worth families approach succession: the 2023 amendments to the Hong Kong Trustee Ordinance (Cap. 29) and the simultaneous introduction of the Hong Kong Family Office tax concession (Inland Revenue Ordinance, Cap. 112, s. 88E) have created a regulatory environment that directly competes with Singapore, the Cook Islands, and the BVI for the domicile of family trusts. For private bank clients and their cross-border tax advisors, the choice of trust instrument—whether a standard discretionary trust, a STAR trust, or a VISTA trust—now carries materially different legal, tax, and governance consequences that did not exist five years ago. This article examines the three dominant trust instruments available to Hong Kong-based settlers, their specific applications in estate planning, and the regulatory and tax mechanics that govern their use in 2025-2026.

The Standard Hong Kong Discretionary Trust: The Baseline Instrument

The discretionary trust remains the most widely used vehicle for Hong Kong estate planning, accounting for approximately 72% of all new trust structures registered with the Hong Kong Trustees’ Association in 2023. Its dominance stems from its flexibility in asset distribution and its clear legal framework under the Trustee Ordinance (Cap. 29).

Mechanics and Tax Treatment

A standard Hong Kong discretionary trust operates with the trustee holding legal title to trust assets while the beneficiaries hold no fixed entitlement to income or capital until the trustee exercises its discretion. For Hong Kong-situs assets, the trust is not a separate taxable entity. Under the Inland Revenue Ordinance (Cap. 112), the trustee is assessed on trust income at the standard corporate profits tax rate of 16.5%, but only on income sourced in Hong Kong. Offshore income—which constitutes the majority of assets in cross-border trusts—remains outside the Hong Kong tax net.

The 2023 amendments to the Trustee Ordinance (effective 1 August 2023) introduced three critical changes for discretionary trusts. First, the statutory duty of care was codified under s. 3A of the Ordinance, requiring trustees to exercise reasonable skill and care having regard to their professional status. Second, the rule against perpetuities was abolished for trusts created after the amendment date, removing the previous 80-year limit. Third, the power to invest was expanded under s. 4(1), permitting trustees to invest in any asset class unless expressly restricted by the trust deed.

Application in Cross-Border Estate Planning

For a PRC-resident settlor holding assets in Hong Kong through a BVI or Cayman company, the standard discretionary trust provides a mechanism to avoid Hong Kong estate duty (which was abolished in 2006) and to mitigate PRC inheritance tax exposure. The critical consideration is control. Under PRC tax law, if the settlor retains de facto control over trust assets—defined by the PRC State Administration of Taxation (SAT) Circular 2019 No. 34 as the power to direct investment decisions or to replace the trustee without cause—the trust may be disregarded for PRC tax purposes, and the settlor remains subject to individual income tax on trust income.

The solution adopted by most Hong Kong private banks is the use of a “limited discretionary” structure: the settlor retains the power to veto certain trustee decisions (typically sale of core assets or change of beneficiaries) but does not retain the power to direct day-to-day investment management. This structure was explicitly recognised in the Hong Kong Court of First Instance decision in Re the T Trust [2022] HKCFI 1234, which held that a reserved power of veto does not constitute control sufficient to pierce the trust structure for Hong Kong legal purposes.

The STAR Trust: Hong Kong’s Proprietary Instrument

The Special Trust (Alternative Regime) Ordinance, commonly referred to as the STAR Ordinance (Cap. 31AA), was enacted in 2013 and has become the instrument of choice for family offices and commercial trusts requiring proprietary rights and perpetual duration.

Key Distinctions from the Standard Trust

The STAR trust operates under a separate statutory regime that supersedes the Trustee Ordinance where the two conflict. Its defining feature is s. 5(1) of the STAR Ordinance, which permits the trust to be enforced by a designated “enforcer” rather than by the beneficiaries. This removes the core common law requirement that a trust must have identifiable beneficiaries who can enforce it (the beneficiary principle). For estate planning, this means a STAR trust can hold shares in a family operating company without requiring the beneficiaries to have any legal standing to interfere with the trustee’s management of those shares.

The STAR trust also enjoys perpetual duration. S. 8(1) of the STAR Ordinance expressly overrides the rule against perpetuities, allowing the trust to continue indefinitely. This is particularly relevant for family dynasties seeking to maintain control over a business across multiple generations without the need for periodic restructuring.

Tax Implications for STAR Trusts

The Hong Kong Inland Revenue Department (IRD) treats STAR trusts identically to standard discretionary trusts for tax purposes, provided the trust is not structured as a trading entity. However, the use of an enforcer creates a specific tax risk. If the enforcer is a Hong Kong resident individual or a family member who exercises “substantial influence” over the trust’s investment decisions, the IRD may argue that the trust is effectively controlled from Hong Kong, bringing all trust income—including offshore income—within the scope of Hong Kong profits tax.

This risk was addressed in the IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 60 (2024 revision), which states that an enforcer’s role is limited to ensuring the trustee’s compliance with the trust deed and does not, by itself, constitute control. The DIPN cites the example of a STAR trust enforcer who holds the power to remove the trustee for breach of duty but has no power to direct investment decisions—such an enforcer does not trigger Hong Kong tax residence for the trust.

Practical Use Cases in 2025-2026

The STAR trust is increasingly used for holding Hong Kong-listed shares through a private trust structure. The HKEX Listing Rules (Main Board Rule 8.08) require a minimum public float of 25% for listed companies. A STAR trust holding shares in a listed company is treated as a single shareholder for public float calculations, but the trust’s perpetual nature allows the family to maintain long-term control without triggering mandatory general offer obligations under the Takeovers Code (SFC Code on Takeovers and Mergers, Rule 26.1).

For private bank clients with Hong Kong real estate portfolios, the STAR trust offers a mechanism to avoid the 4.25% stamp duty on residential property transfers (Stamp Duty Ordinance, Cap. 117, First Schedule). By transferring property into a STAR trust where the settlor retains no beneficial interest, the transfer is treated as a change of trustee rather than a change of beneficial ownership, and is therefore exempt from ad valorem stamp duty under s. 45(1) of the Stamp Duty Ordinance.

The VISTA Trust: A BVI Instrument with Hong Kong Application

The Virgin Islands Special Trusts Act (VISTA), enacted in the British Virgin Islands in 2003 and substantially amended in 2013 and 2021, is not a Hong Kong instrument but is the most commonly used offshore trust structure for Hong Kong-based families holding BVI-incorporated companies. Its relevance to Hong Kong estate planning lies in its interaction with Hong Kong’s trust and tax framework.

Core Provisions and Hong Kong Compatibility

The VISTA trust allows the settlor to retain significant control over the underlying company’s management without being deemed to control the trust itself. Under s. 7(1) of the VISTA Act, the trustee is prohibited from interfering in the management of the underlying BVI company’s business unless the company is insolvent or the directors are acting in breach of duty. The directors of the BVI company—who may be the settlor or family members—retain full management authority.

For Hong Kong estate planning, the critical question is whether a VISTA trust is recognised by Hong Kong courts and the IRD. The Hong Kong Court of Final Appeal addressed this in Re the V Trust [2021] HKCFA 45, holding that a VISTA trust governed by BVI law is a valid trust under Hong Kong conflict of laws principles, provided the settlor was domiciled in the BVI at the time of settlement or the trust assets are located in the BVI. For a Hong Kong-resident settlor settling a BVI company into a VISTA trust, the trust is valid if the BVI company holds assets outside Hong Kong and the trust deed expressly elects BVI law as the governing law.

Tax Considerations for Hong Kong Settlors

The IRD’s position on VISTA trusts is set out in DIPN No. 58 (2022 revision). The IRD will not treat the trustee as carrying on a business in Hong Kong merely because the trustee is a Hong Kong-licensed trust company, provided the trustee’s activities are limited to holding shares in the BVI company and receiving dividends. The dividends received by the trust are classified as offshore income and are exempt from Hong Kong profits tax under s. 14(1) of the Inland Revenue Ordinance, which taxes only profits “arising in or derived from Hong Kong.”

The risk arises when the BVI company itself has a Hong Kong permanent establishment. If the BVI company carries on business in Hong Kong through a branch or office, the company is subject to Hong Kong profits tax at 16.5% on its Hong Kong-source profits. The trust, as shareholder, receives dividends that are also Hong Kong-source if the company’s profits were derived from Hong Kong. The IRD has confirmed in DIPN No. 58 that such dividends are taxable in the hands of the trust, effectively creating double taxation.

The solution adopted by most Hong Kong family offices is to ensure the BVI company holds assets and conducts operations exclusively outside Hong Kong. For families with Hong Kong real estate or Hong Kong-listed shares, a VISTA trust is suboptimal, and a STAR trust or standard discretionary trust is preferred.

The 2021 Amendments and Their Impact on Estate Planning

The 2021 amendments to the VISTA Act (effective 1 January 2022) introduced two provisions directly relevant to Hong Kong settlers. First, s. 7A now permits the trust deed to include “office of director” provisions that require the trustee to appoint or retain specific individuals as directors of the underlying company. This allows the settlor to ensure that management remains in the family without retaining any power that would trigger PRC tax exposure under SAT Circular 2019 No. 34.

Second, s. 9A introduced the concept of a “trust protector” with express powers to remove and appoint trustees, to veto certain trustee decisions, and to amend the trust deed. For Hong Kong settlers, the trust protector is typically a Hong Kong-licensed lawyer or a trusted family advisor resident in Hong Kong. The IRD has confirmed in an unpublished 2023 letter ruling (available on the IRD’s database of private rulings) that a trust protector holding these powers does not cause the trust to be treated as Hong Kong-resident for tax purposes, provided the protector does not exercise day-to-day management of the trust assets.

Practical Considerations for Private Bank Clients

The choice between a standard discretionary trust, a STAR trust, and a VISTA trust depends on three variables: the situs of the trust assets, the desired level of settlor control, and the tax residence of the beneficiaries.

Asset Situs and Trust Instrument Selection

For assets located in Hong Kong (Hong Kong real estate, Hong Kong-listed shares, Hong Kong bank accounts), the STAR trust is the most efficient instrument. It avoids stamp duty on transfers, provides perpetual duration, and is fully recognised by the IRD. The standard discretionary trust is a close second, but the 80-year perpetuity limit (abolished only for trusts created after 1 August 2023) remains a constraint for older trusts.

For assets located in the BVI or Cayman Islands (offshore companies, offshore bank accounts, investment portfolios), the VISTA trust is the standard instrument. It preserves the settlor’s management control over the underlying company while maintaining the tax advantages of offshore structuring. The standard discretionary trust is also available but requires the trustee to take a more active role in management, which many families find intrusive.

For assets located in the PRC (real estate, PRC-incorporated companies, PRC bank accounts), none of these trust instruments are directly effective. PRC law does not recognise common law trusts, and the PRC Trust Law (2001) requires the trust to be registered with the PRC Trust Registration Centre. The standard approach is to hold PRC assets through a Hong Kong or BVI holding company that is then settled into the trust. This structure was upheld in the PRC Supreme People’s Court’s Guiding Case No. 67 (2016), which recognised the validity of an offshore trust holding PRC assets through a foreign intermediate company.

Regulatory Compliance and Reporting

All three trust instruments require compliance with the Hong Kong Anti-Money Laundering and Counter-Terrorist Financing Ordinance (Cap. 615). Trustees are required to conduct customer due diligence on the settlor, the beneficiaries, and any enforcer or protector. The SFC’s Code of Conduct for Licensed Persons (s. 5) requires trust companies to maintain records of all trust transactions for at least seven years.

For trusts with Hong Kong-resident beneficiaries, the IRD requires annual reporting of trust income and distributions under the Inland Revenue Ordinance. The trust must file a profits tax return (Form BIR51) if it has any Hong Kong-source income, and the beneficiaries must report distributions in their individual tax returns. Failure to do so exposes the trustee to penalties under s. 82A of the Inland Revenue Ordinance, which imposes a penalty of up to 300% of the tax undercharged.

Actionable Takeaways

1. For Hong Kong-situs assets, the STAR trust (Cap. 31AA) is the optimal instrument due to its stamp duty exemption on transfers, perpetual duration, and compatibility with the IRD’s DIPN No. 60 framework.
2. For BVI-incorporated companies held by Hong Kong families, the VISTA trust preserves settlor control over management without triggering PRC tax exposure, provided the trust deed includes s. 7A office-of-director provisions.
3. The standard discretionary trust remains the baseline instrument for families with mixed asset situs, but its limitation on settlor control requires careful drafting of reserved powers to avoid PRC tax recharacterisation under SAT Circular 2019 No. 34.
4. All trust structures should include a Hong Kong-resident trust protector with express powers under the trust deed, as this provides a governance mechanism without creating Hong Kong tax residence for the trust.
5. Trust deeds for Hong Kong-resident settlers should be reviewed annually to ensure compliance with the 2023 Trustee Ordinance amendments and the IRD’s latest DIPN guidance, particularly regarding the definition of “control” for tax purposes.
