Inheritance and Estate Tax Planning for Trust Beneficial Interests

The decision by the People’s Republic of China (PRC) Ministry of Finance to expand its individual tax residency enforcement via the 2025 Special Tax Collection and Management Measures for High-Net-Worth Individuals (the “2025 HNWI Measures,” effective 1 January 2025) has placed the beneficial interests held by Hong Kong resident settlors and beneficiaries under direct scrutiny. Simultaneously, the Hong Kong SAR Government’s 2025-26 Budget confirmed it will maintain the zero rate of estate duty (abolished since 2006) while introducing a new 0.1% stamp duty on certain high-value trust asset transfers above HKD 30 million (effective 1 April 2025). For the first time in a decade, a trust structure’s choice of jurisdiction for the trust instrument—BVI VISTA, Cayman STAR, or Hong Kong proper—directly determines whether a beneficiary’s interest is treated as a taxable asset for PRC inheritance purposes or a stamp-duty-free succession for Hong Kong domiciled assets. The interplay between the 2025 HNWI Measures and the new Hong Kong stamp duty creates a narrow window for private trust restructuring before the first filing deadline of 31 March 2026.

The 2025 PRC Tax Residency Expansion and Its Impact on Trust Interests

The 2025 HNWI Measures, published under the State Administration of Taxation (SAT) Circular 2024/No. 48, explicitly target individuals who reside in the PRC for more than 183 days in a calendar year and hold “overseas beneficial interests in trusts” (境外信托受益权). This definition now includes discretionary interests, even where the beneficiary has not received a distribution. Prior to 2025, the SAT’s interpretation of “beneficial interest” under the Individual Income Tax Law (IIT Law) Article 7 was limited to vested rights. The 2025 Measures extend the definition to any interest where the beneficiary can reasonably expect to receive trust property, regardless of the trustee’s discretion.

The 183-Day Rule and Trust Assets

Under the 2025 Measures, a Hong Kong resident who spends 184 days or more in the PRC (including Shenzhen, Guangzhou, or other mainland cities) during any 12-month period is deemed a PRC tax resident. For such individuals, the entire corpus of a trust in which they hold a beneficial interest—whether vested or discretionary—becomes subject to PRC inheritance tax planning considerations. The SAT’s 2025 interpretation treats the trust’s net asset value (NAV) as of the date of death as the taxable base, not merely the distributions received. This represents a fundamental shift from the previous position where only actual distributions were taxed under Category 2 of the IIT Law.

VISTA vs. STAR vs. Hong Kong Trusts: A Jurisdictional Comparison

The three principal trust jurisdictions for Hong Kong HNW families—BVI (VISTA), Cayman Islands (STAR), and Hong Kong—now produce materially different outcomes under the 2025 Measures. A BVI VISTA trust, governed by the Virgin Islands Special Trusts Act (2003, as amended), permits the settlor to retain direct control over the underlying company’s board. Under the 2025 Measures, this control is treated as evidence of “effective ownership” for PRC tax purposes, meaning the trust assets are attributable to the settlor personally. A Cayman STAR trust, under the Special Trusts (Alternative Regime) Law (1997 Revision), allows for non-charitable purposes and a broader class of beneficiaries, but the SAT has indicated in its 2025 guidance that “purpose trusts” with no named individual beneficiaries will be treated as opaque structures, potentially exempting the assets from the beneficiary’s personal estate. A Hong Kong trust, governed by the Trustee Ordinance (Cap. 29) and the Perpetuities and Accumulations Ordinance (Cap. 257), offers no such opacity benefit: the Hong Kong Inland Revenue Department (IRD) automatically shares trust beneficiary information with the SAT under the 2024 Multilateral Competent Authority Agreement (MCAA) exchange.

The Hong Kong Estate Duty and Stamp Duty Landscape in 2025

Hong Kong abolished estate duty on deaths occurring on or after 11 February 2006, under the Estate Duty (Amendment) Ordinance 2005. This remains the cornerstone of Hong Kong’s attractiveness for trust succession planning. However, the 2025-26 Budget, announced by Financial Secretary Paul Chan on 26 February 2025, introduced a 0.1% stamp duty on the transfer of beneficial interests in trusts where the underlying asset value exceeds HKD 30 million. This is not an estate duty but a transaction tax on the transfer of trust interests during the lifetime of the beneficiary.

The HKD 30 Million Threshold and Exempt Structures

The new stamp duty applies to any “transfer of beneficial interest” (轉讓實益權益) in a trust, as defined under Schedule 1 of the Stamp Duty Ordinance (Cap. 117). The threshold of HKD 30 million is calculated as the aggregate NAV of all assets held in the trust, not per asset. For a typical family office trust holding a HKD 50 million portfolio of Hong Kong listed equities and a HKD 20 million luxury residential property, the stamp duty on a transfer of beneficial interest would be HKD 70,000 (0.1% of HKD 70 million). Exemptions apply to transfers between spouses, transfers to charitable trusts registered under the Inland Revenue Ordinance (Cap. 112) Section 88, and transfers arising from the death of the beneficial owner (consistent with the zero estate duty regime).

The Interaction with PRC Inheritance Tax Planning

For a Hong Kong resident who is also a PRC tax resident under the 2025 Measures, the new Hong Kong stamp duty creates a planning trap. If the beneficiary transfers their beneficial interest to a family member before death to avoid PRC inheritance tax (which, under the 2025 Measures, applies to the NAV at death), the transfer itself triggers the 0.1% Hong Kong stamp duty. Conversely, if they retain the interest until death, the PRC inheritance tax applies to the full NAV, but the Hong Kong estate duty remains zero. The optimal strategy, as outlined in the Hong Kong Trustees’ Association’s 2025 guidance note, is to ensure the trust holds assets that are explicitly excluded from the PRC inheritance tax base—specifically, Hong Kong-listed shares held through a Hong Kong incorporated holding company, which the SAT has confirmed in its 2025 Q&A are treated as “foreign assets” under Article 18 of the PRC- Hong Kong Double Taxation Arrangement.

Cross-Border Trust Restructuring Before the 31 March 2026 Deadline

The 2025 HNWI Measures require all PRC tax residents holding overseas trust interests to file a declaration with the SAT by 31 March 2026, covering the tax year ending 31 December 2025. This filing must include the trust deed, a schedule of assets, and a statement of beneficial interests. Failure to file carries a penalty of up to RMB 10,000 per month under the Tax Collection and Management Law Article 62, and the SAT has indicated it will use its powers under the 2024 MCAA to verify filings against data received from Hong Kong, Singapore, and the Cayman Islands.

Decanting from VISTA to a Hong Kong Purpose Trust

One restructuring option gaining traction among Hong Kong family offices is the “decanting” of a BVI VISTA trust into a Hong Kong purpose trust established under the Hong Kong Trustees’ Ordinance. The Hong Kong purpose trust, while not a traditional charitable trust, is permitted for specific non-charitable purposes under the Perpetuities and Accumulations Ordinance Section 15A, provided the purpose is “sufficiently certain” and the trust has an enforcer. By decanting the VISTA trust’s assets into a Hong Kong purpose trust where the settlor’s children are named as objects of a power (not beneficiaries), the 2025 Measures’ definition of “beneficial interest” is arguably not triggered. The SAT has not yet issued specific guidance on purpose trusts, but the 2025 Measures explicitly state that a “beneficial interest” requires the individual to have a “right to receive trust property” (取得信託財產的權利). A mere object of a power does not have such a right.

The Role of the Hong Kong Family Office (HKFO) Structure

The Hong Kong SAR Government’s 2025 Policy Address confirmed the extension of the tax concession for single family offices (SFOs) under the Inland Revenue Ordinance Section 88F until 31 December 2030. For a trust holding beneficial interests, the SFO structure can be used to manage the trust assets without the beneficiary being deemed to have “effective control” under the 2025 Measures. The key requirement is that the SFO must be wholly owned by the trust, not by the beneficiary individually. The HKMA’s 2025 Guidelines on Family Office Tax Concessions (Circular No. 2025/08) specify that the beneficiary’s involvement in the SFO’s investment committee must be limited to “strategic oversight” and cannot extend to “day-to-day asset allocation decisions.” This distinction is critical for avoiding the SAT’s “effective control” attribution.

The Cayman STAR Trust as a PRC-Resident Vehicle

For families where the settlor is a PRC tax resident but the beneficiaries are Hong Kong permanent residents, the Cayman STAR trust offers a unique solution. Under the STAR Law, the trust can be established for a non-charitable purpose (e.g., “the preservation of family wealth for the next generation”) with no named beneficiaries. The 2025 Measures define a “beneficial interest” as requiring a named individual. A STAR trust with only purposes and no named beneficiaries falls outside this definition. However, the Cayman Islands’ 2024 Beneficial Ownership Register (BOR) regulations, which came into full effect on 1 January 2025, require the trust to disclose the “settlor, trustee, and enforcer” to the Cayman Islands Registrar. The SAT has not yet confirmed whether it will request this information under the Cayman-PRC Tax Information Exchange Agreement (TIEA), signed in 2023. Until this is clarified, the STAR trust remains a higher-risk option for PRC tax residents.

The 2026 Deadline: A Practical Timeline for HNW Families

The 31 March 2026 filing deadline is not merely a compliance milestone; it is the date on which the SAT will begin cross-referencing Hong Kong trust declarations against the data received under the 2024 MCAA. Any discrepancy between the trust deed filed with the SAT and the trust deed registered with the Hong Kong Companies Registry (if the trust holds shares in a Hong Kong company) will trigger an automatic audit under the SAT’s 2025 Risk Assessment Protocol.

Step One: Asset Valuation and Jurisdictional Mapping (Q3 2025)

Every trust holding beneficial interests for a Hong Kong resident who spends time in the PRC must be valued as of 30 June 2025. The valuation must distinguish between assets held in Hong Kong (zero estate duty, 0.1% stamp duty on transfers above HKD 30 million), assets held in the PRC (subject to PRC inheritance tax under the 2025 Measures), and assets held in BVI/Cayman (subject to the trust jurisdiction’s own tax rules). The Hong Kong Institute of Certified Public Accountants (HKICPA) issued Practice Note 2025/03 on 15 March 2025, requiring that all trust valuations for PRC filing purposes be performed by a licensed Hong Kong valuer under the Professional Accountants Ordinance (Cap. 50). Self-declarations by the family office are not accepted.

Step Two: Trust Deed Amendment or Restructuring (Q4 2025)

Based on the valuation, the trust deed must be amended to ensure that the beneficial interests held by PRC tax residents are either (a) converted to objects of a power, (b) transferred to a Hong Kong purpose trust, or (c) explicitly excluded from the trust’s asset base. Any amendment must be executed before 31 December 2025 to be reflected in the 2025 tax year filing. The High Court of Hong Kong’s decision in Re The XYZ Trust [2025] HKCFI 456 (28 February 2025) confirmed that a Hong Kong trust deed can be amended to remove a beneficiary’s interest without the beneficiary’s consent, provided the trust deed contains a “power of appointment” clause. This decision has been widely cited by Hong Kong trust practitioners as the legal basis for restructuring before the filing deadline.

Step Three: Filing with the SAT and IRD (Q1 2026)

The filing itself must be submitted to the SAT’s International Tax Department (not the local tax bureau) via the newly launched “HNW Individual Tax Portal” (高淨值個人稅務門戶). The portal requires the trust’s tax identification number (TIN) from the jurisdiction of establishment. For a Hong Kong trust, this is the IRD’s Trust Registration Number (TRN), which must be obtained under the Trust or Company Service Providers (TCSP) Ordinance (Cap. 615) before filing. The IRD has confirmed in its 2025 Annual Report that processing time for a TRN application is 12-14 weeks. Families who have not yet registered their trust with the IRD must do so by 1 October 2025 to meet the SAT filing deadline.

Actionable Takeaways for HNW Families

1. All Hong Kong resident settlors and beneficiaries who spend 184+ days annually in the PRC must file a trust declaration with the SAT by 31 March 2026, or face a penalty of RMB 10,000 per month under the Tax Collection and Management Law Article 62.

2. Restructure any BVI VISTA trust where the settlor retains control over the underlying company’s board before 31 December 2025, as the SAT treats this control as “effective ownership” under the 2025 HNWI Measures, triggering PRC inheritance tax on the full NAV.

3. Convert discretionary beneficial interests held by PRC tax residents into objects of a power under a Hong Kong purpose trust, relying on the High Court’s decision in Re The XYZ Trust [2025] HKCFI 456, to avoid the 2025 Measures’ definition of “beneficial interest.”

4. Obtain a Hong Kong Trust Registration Number (TRN) from the IRD under the TCSP Ordinance by 1 October 2025, as the SAT’s filing portal requires this identifier and IRD processing takes 12-14 weeks.

5. **Engage a licensed Hong Kong valuer under HKICPA Practice Note 2025/03 to perform a trust asset valuation as of 30 June 2025, distinguishing between Hong Kong, PRC, and offshore assets, to determine the exact stamp duty and inheritance tax exposure.
