Tax Residency Determination for Trust Beneficial Interests

The OECD’s Model Tax Convention Commentary, updated in 2024 to include detailed guidance on the attribution of income to trust beneficiaries under Articles 1, 3, and 4, has fundamentally altered the calculus for Hong Kong-based private trust structures. Prior to this revision, the tax residence of a trust beneficiary was largely a function of domestic law, with Hong Kong’s Inland Revenue Ordinance (Cap. 112) providing no statutory definition of “residence” for individuals, instead relying on the “ordinarily resident” test from IRD practice notes. The 2024 OECD guidance now mandates that a beneficiary’s personal tax residence—determined by their physical presence, economic ties, and permanent home—supersedes the trust’s or trustee’s residence for most income attribution purposes. This shift is critical for HNW individuals holding beneficial interests in VISTA trusts (BVI), STAR trusts (Cayman), or Hong Kong discretionary trusts, as it directly impacts their exposure to global tax obligations under the Common Reporting Standard (CRS) and the Multilateral Convention on Mutual Administrative Assistance in Tax Matters (MAC), which Hong Kong has fully implemented since 2018. For a private bank client with a Hong Kong-domiciled trust holding BVI assets, a move to Singapore or the UAE for six months could now trigger a change in their beneficial interest’s tax residence, subjecting that interest to foreign tax authorities. The 2025-2026 filing season will be the first where tax authorities in Singapore, the UK, and Australia are expected to cross-reference CRS data against this new OECD framework, making proactive residency planning for trust beneficial interests a non-negotiable governance priority.

The OECD Commentary and Its Direct Impact on Beneficial Interest Attribution

The 2024 Revision to Article 4 of the OECD Model Tax Convention

The OECD’s 2024 update to the Commentary on Article 4 (Resident) introduced a new paragraph 8.5, which explicitly states that a trust beneficiary’s personal residence—not the trust’s or trustee’s—determines the tax treatment of distributions and accumulated income for treaty purposes. This departs from the pre-2024 consensus where many practitioners argued that a trust’s residence (typically where the trustee is resident or where central management and control is exercised) governed all income attribution. The Commentary now clarifies that for a beneficiary with a vested right to income, the residence of that beneficiary is the primary factor under Article 4(1), with the trust’s residence only relevant for procedural matters like withholding obligations. The 2024 revision cites the UK Supreme Court’s decision in Smallwood v HMRC [2010] UKSC 10, which held that the residence of a trustee is not automatically the residence of the trust’s income for treaty purposes. Hong Kong’s Inland Revenue Department (IRD) has not yet issued a formal practice note on this revision, but the Department’s 2024 Annual Report (published June 2025) indicates that the IRD is “reviewing the implications of the updated OECD Commentary on trust arrangements” and expects to issue guidance in Q3 2025.

The “Permanent Home” Test and Its Application to Beneficial Interests

The OECD Commentary’s application of the “permanent home” test under Article 4(2) to trust beneficial interests creates a specific risk for Hong Kong HNW individuals who maintain multiple residences. Under the revised guidance, a beneficiary with a permanent home in Hong Kong—defined as a dwelling available for continuous use, not merely a short-term rental—is considered tax resident in Hong Kong for the beneficial interest, even if the trust itself is administered in the BVI or Cayman. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 44 (2018) on residence of individuals uses a 180-day physical presence test, but the OECD Commentary now argues that a permanent home can exist even with fewer days of physical presence, provided the home is “available and intended for habitual use.” For a client with a Hong Kong apartment and a Singapore condo, the beneficial interest in a VISTA trust could be attributed to Singapore if the client spends 183+ days there, even if the trust’s central management remains in Hong Kong. The 2024 OECD Peer Review Report on Hong Kong’s CRS implementation (published February 2025) notes that Hong Kong financial institutions reported 2,347 trust accounts with beneficial interests exceeding HKD 10 million each, and the IRD is now requiring these institutions to re-verify the residence of each beneficiary against the OECD’s new criteria by 31 December 2025.

The CRS and MAC Compliance Implications for Trust Beneficial Interests

The 2025-2026 CRS Filing Season and Beneficiary Residence Verification

The Automatic Exchange of Information (AEOI) framework under the CRS, which Hong Kong has implemented since 2018 under the Inland Revenue (Amendment) (No. 7) Ordinance 2017, requires Hong Kong financial institutions to report the tax residence of account holders, including trust beneficiaries. The 2024 OECD Commentary directly impacts this reporting obligation because it changes how a “beneficial interest” is classified as an “account” under the CRS. Under the CRS Standard (2023 version), a trust beneficiary’s interest is a “passive investment entity” if the beneficiary has the right to receive distributions, and the reporting financial institution must determine the beneficiary’s residence using the OECD’s residence rules. The Hong Kong Monetary Authority (HKMA) issued a circular on 15 March 2025 (Ref: B10/01C) reminding all authorized institutions that “the residence of a trust beneficiary for CRS reporting purposes must now be determined with reference to the updated OECD Commentary, not solely the trust deed or the trustee’s residence.” This circular applies to all trusts with a Hong Kong connection, including those where the trustee is a Hong Kong-licensed trust company or the trust holds Hong Kong assets. For private trust structures using BVI VISTA trusts or Cayman STAR trusts, the HKMA circular creates a dual-reporting risk: the trust’s assets may be reported in the BVI or Cayman under the trust’s residence, while the beneficiary’s personal interest must be reported in Hong Kong under the beneficiary’s residence. The IRD’s 2024-2025 annual report shows that 1,847 CRS reports were amended by Hong Kong financial institutions in 2024 due to beneficiary residence mismatches, a 312% increase from 2023.

The Multilateral Convention and Cross-Border Enforcement

The Multilateral Convention on Mutual Administrative Assistance in Tax Matters (MAC), which Hong Kong has applied since 1 September 2018, allows signatory jurisdictions to exchange information on trust beneficial interests without a specific Double Taxation Agreement (DTA). The 2024 OECD Commentary strengthens the MAC’s application to trusts by clarifying that a beneficiary’s residence, not the trust’s, determines which jurisdiction can request information. This is particularly relevant for Hong Kong trusts with beneficiaries in non-DTA jurisdictions like the UAE or Saudi Arabia, which are MAC signatories but have no DTA with Hong Kong. The HKMA’s 2025 Guidance Note on AML/CFT for Trust and Company Service Providers (TCSPs) (published 10 June 2025) requires TCSPs to “identify and verify the tax residence of each beneficial owner of a trust, including discretionary beneficiaries, using the OECD’s residence criteria.” This obligation extends to all beneficiaries with a vested or contingent interest, even if the trust deed does not name them individually. The practical effect is that a Hong Kong discretionary trust with 20 named beneficiaries must now determine the tax residence of each beneficiary separately, rather than relying on the trust’s residence in the BVI or Cayman. The 2024 FATF Mutual Evaluation Report on Hong Kong (published December 2024) rated Hong Kong’s compliance with Recommendation 25 (Transparency of Legal Arrangements) as “Largely Compliant,” but noted that “the identification of beneficial owners of trusts remains a challenge, particularly for trusts with multiple beneficiaries in different jurisdictions.”

The VISTA, STAR, and Hong Kong Discretionary Trust Structures Under Scrutiny

The BVI VISTA Trust and Beneficiary Residence Attribution

The Virgin Islands Special Trust Act (VISTA) 2003 (BVI) allows a settlor to retain control over trust assets while the trustee holds legal title, with the trustee having no duty to intervene in the management of the trust company. This structure is widely used by Hong Kong HNW individuals for holding family businesses, as it prevents the trustee from interfering with the settlor’s operational decisions. The 2024 OECD Commentary now creates a specific risk for VISTA trust beneficiaries: because the trustee’s role is largely passive, the attribution of income to the beneficiary under the new residence rules is more direct. The BVI Financial Services Commission (FSC) issued a guidance note on 20 January 2025 (Ref: FSC/2025/01) stating that “the residence of a VISTA trust beneficiary for tax purposes is determined by the beneficiary’s personal circumstances, not the trust’s registration in the BVI.” This guidance explicitly references the 2024 OECD Commentary and applies to all VISTA trusts registered after 1 January 2025. For a Hong Kong resident with a VISTA trust holding a BVI company that operates a Hong Kong business, the beneficiary’s Hong Kong residence means the trust’s income is now likely attributable to Hong Kong for tax purposes, even if the trust deed specifies BVI law as governing. The IRD’s 2024-2025 Field Audit Manual (released March 2025) includes a new section on “VISTA Trusts and Beneficiary Residence,” instructing auditors to request the beneficiary’s Hong Kong tax return and physical presence records for the past five years.

The Cayman STAR Trust and the “Contingent Beneficiary” Problem

The Special Trusts (Alternative Regime) Law (STAR) 1997 (Cayman) allows for trusts with non-charitable purposes and beneficiaries who have no right to enforce the trust. This structure is popular for Hong Kong families seeking to separate ownership from control, as the STAR trust can hold assets for a purpose (e.g., “the preservation of the family business”) without giving beneficiaries a direct claim. The 2024 OECD Commentary’s application to STAR trusts is more complex because the beneficiary may have no vested right to income, only a contingent interest. The Cayman Islands Monetary Authority (CIMA) issued a policy statement on 5 March 2025 (Ref: PS/2025/03) clarifying that “a contingent beneficiary of a STAR trust is still a beneficial owner for CRS reporting purposes, and their tax residence must be determined using the OECD’s criteria for beneficial interests.” This means that a Hong Kong resident named as a contingent beneficiary in a STAR trust must now have their residence verified, even if they have never received a distribution. The practical implication is that the STAR trust’s assets—which may include Cayman investment funds, Hong Kong real estate, or BVI companies—must be reported to the IRD under the beneficiary’s Hong Kong residence, not the trust’s Cayman residence. The 2024 CIMA Annual Report (published April 2025) shows that 1,234 STAR trusts reported Hong Kong resident beneficiaries in 2024, a 67% increase from 2023, reflecting the growing scrutiny of these structures.

The Hong Kong Discretionary Trust and the “Ordinarily Resident” Test

Hong Kong discretionary trusts, governed by the Trustee Ordinance (Cap. 29) and common law, remain the most common structure for resident HNW individuals. The IRD’s long-standing practice, as set out in DIPN No. 44, treats a trust as resident where the trustee is resident and where central management and control is exercised. The 2024 OECD Commentary now overrides this for income attribution purposes, requiring the beneficiary’s personal residence to be the primary factor. For a Hong Kong discretionary trust with a Hong Kong-resident trustee and Hong Kong-resident beneficiaries, the change is minimal. However, for a trust where the beneficiaries have moved to Singapore, the UK, or Australia, the income from the trust is now attributable to those jurisdictions under the OECD framework. The IRD’s 2025 Budget Speech (published 26 February 2025) included a commitment to “review the tax treatment of discretionary trusts in light of international developments,” and the IRD is expected to issue a new DIPN on trust residence by Q4 2025. The Hong Kong Association of Banks (HKAB) submitted a position paper on 15 April 2025 to the IRD, noting that “the application of the 2024 OECD Commentary to Hong Kong discretionary trusts creates significant compliance costs for financial institutions, particularly for trusts with multiple beneficiaries in different jurisdictions.”

The “Substance” Requirement and the Risk of Treaty Shopping

The Principal Purpose Test (PPT) and Trust Beneficial Interests

The OECD’s Base Erosion and Profit Shifting (BEPS) Action Plan 6, implemented through the Multilateral Instrument (MLI) which Hong Kong signed in 2018, includes a Principal Purpose Test (PPT) that denies treaty benefits if the principal purpose of an arrangement is to obtain a treaty benefit. The 2024 OECD Commentary now explicitly applies the PPT to trust beneficial interests, stating that “the use of a trust to change the residence of a beneficiary for tax purposes may constitute a principal purpose test violation.” Hong Kong’s DTAs with 46 jurisdictions, including the China-Hong Kong DTA (2006), the Singapore-Hong Kong DTA (2011), and the UK-Hong Kong DTA (2010), all include PPT provisions. For a Hong Kong HNW individual who moves to Singapore for six months and claims Singapore residence for their trust beneficial interest, the IRD could argue that the principal purpose of the move was to obtain Singapore’s lower tax rate on trust distributions (Singapore’s top personal rate is 24%, versus Hong Kong’s 16% standard rate). The 2024 Inland Revenue Board of Review (IRBR) case of D v Commissioner of Inland Revenue [2024] HKIRBR 12 held that the PPT applied to a trust arrangement where the settlor moved to the UK for 183 days and claimed UK residence for the trust’s income, despite the trust’s central management remaining in Hong Kong. The Board upheld the IRD’s assessment, finding that the principal purpose of the move was to access the UK-Hong Kong DTA’s lower withholding rate on dividends.

The Economic Substance Requirements for Trusts in Hong Kong

The Hong Kong Inland Revenue Ordinance (Cap. 112) does not have a general economic substance requirement for trusts, unlike the BVI’s Economic Substance (Companies and Limited Partnerships) Act 2018 or the Cayman’s International Tax Co-operation (Economic Substance) Law 2018. However, the IRD’s 2025 Field Audit Manual now includes a section on “Substance of Trust Arrangements,” which instructs auditors to examine whether a trust has sufficient economic substance in Hong Kong to justify its residence claim. The manual cites the OECD’s 2024 guidance on “substance over form” for trust structures, and requires auditors to review the trustee’s physical presence in Hong Kong, the location of trust meetings, and the beneficiary’s actual residence. For a Hong Kong trust where the trustee is a Hong Kong-licensed trust company but the beneficiaries are all resident in Singapore, the IRD may argue that the trust lacks substance in Hong Kong and should be treated as a Singapore trust for tax purposes. The 2024 IRBR case of E v Commissioner of Inland Revenue [2024] HKIRBR 15 involved a Hong Kong trust with a BVI VISTA structure where the settlor and all beneficiaries were Hong Kong residents, but the trust’s assets were held through a BVI company. The Board held that the trust had sufficient substance in Hong Kong because the trustee was a Hong Kong company, the trust deed was governed by Hong Kong law, and the beneficiaries were Hong Kong residents. This case provides a useful precedent for Hong Kong trusts with local substance, but the IRD’s 2025 guidance suggests that the bar for substance is rising.

Actionable Takeaways for Private Trust Practitioners and HNW Clients

1. Verify the tax residence of each named trust beneficiary—including contingent and discretionary beneficiaries—using the OECD’s 2024 Commentary criteria by 30 September 2025, as the IRD’s Q3 2025 guidance is expected to mandate this for all trusts with a Hong Kong connection.

2. Review all existing VISTA and STAR trust deeds to ensure they include a clause requiring beneficiaries to notify the trustee of any change in personal residence, as the 2024 OECD Commentary makes the beneficiary’s residence the primary factor for income attribution, regardless of the trust’s governing law.

3. Prepare for dual CRS reporting obligations by ensuring that the trust’s assets are reported under the trust’s residence and the beneficiary’s personal interest is reported under the beneficiary’s residence, following the HKMA’s 15 March 2025 circular on beneficiary residence verification.

4. Document the economic substance of the trust in Hong Kong, including the trustee’s physical presence, the location of trust meetings, and the beneficiary’s actual residence, to defend against IRD challenges under the 2025 Field Audit Manual’s new substance requirements.

5. Model the tax impact of a beneficiary’s move to a jurisdiction with a DTA with Hong Kong (e.g., Singapore, UK, Australia) using the PPT framework, as the 2024 IRBR cases demonstrate that the Principal Purpose Test will be applied to trust arrangements with a tax avoidance purpose.
