Accounting and Financial Reporting Standards for Hong Kong Family Trusts

The Hong Kong Inland Revenue Department (IRD) has materially intensified its scrutiny of family trust structures since the 2024-2025 fiscal year, driven by the implementation of the Economic Substance Requirements (ESR) for Hong Kong-resident trust companies and the revised Transfer Pricing (TP) Ordinance (Cap. 112). For UHNW families with assets exceeding USD 10 million, the choice of accounting framework and the accuracy of financial reporting for their Hong Kong trusts are no longer a mere compliance formality but a direct determinant of tax liability, regulatory risk, and cross-border inheritance planning efficiency. A trust’s financial statements now serve as the primary evidence for the IRD to assess whether a trust is genuinely managed in Hong Kong, whether its income is subject to profits tax under Section 14 of the Inland Revenue Ordinance (Cap. 112), and whether a deemed disposal of assets has occurred under the new TP rules. This article provides a technical, practitioner-oriented analysis of the accounting standards applicable to Hong Kong family trusts, the financial reporting obligations under the Companies Ordinance (Cap. 622) and the Trustee Ordinance (Cap. 29), and the specific disclosure requirements that directly impact the tax residence and substance of the trust structure.

The Applicable Accounting Frameworks for Hong Kong Family Trusts

Hong Kong Financial Reporting Standards (HKFRS) as the Default Standard

For a Hong Kong family trust structured as a corporate trustee company — the most common vehicle for UHNW families — the financial statements must be prepared in accordance with Hong Kong Financial Reporting Standards (HKFRS) as promulgated by the Hong Kong Institute of Certified Public Accountants (HKICPA). This is mandated by Section 380 of the Companies Ordinance (Cap. 622) for all companies incorporated in Hong Kong, including those acting solely as trustees. The HKICPA’s Practice Note 810.1 (Revised 2023) specifically addresses the financial reporting of trust accounts, clarifying that the trustee company must present the trust’s assets, liabilities, income, and expenses in its own financial statements, either as a separate schedule or as a note disclosure, unless the trust is a “structured entity” under HKFRS 10 Consolidated Financial Statements.

The practical implication is significant. A family office acting as a corporate trustee must apply HKFRS 9 Financial Instruments to classify and measure the trust’s investment portfolio (equities, bonds, private equity interests, and derivatives). For a typical multi-asset trust with HKD 200 million in assets, the classification under HKFRS 9 — amortised cost, fair value through other comprehensive income (FVOCI), or fair value through profit or loss (FVTPL) — directly determines the volatility of reported net income and, consequently, the trust’s distributable income and the IRD’s assessment of its profits tax liability. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 60 (2024) explicitly references HKFRS 9 as the basis for determining the “realised” vs. “unrealised” nature of gains for tax purposes, a critical distinction for trusts seeking to minimise tax exposure.

The Alternative: Hong Kong Private Company Reporting Standards (HKPCS)

For smaller family trusts where the corporate trustee qualifies as a “private company” under Section 359 of the Companies Ordinance (Cap. 622) — defined as a company that is not a listed company, not a subsidiary of a listed company, and has no more than 50 members — the directors may elect to apply the Hong Kong Private Company Reporting Standards (HKPCS). HKPCS is a simplified, cost-reduced framework that permits the omission of certain disclosures, including segment reporting, earnings per share, and related party transactions that are not with key management personnel.

However, this election carries a material risk in the context of IRD audits. The IRD’s DIPN No. 48 (Revised 2022) on Transfer Pricing states that for related party transactions involving a trust and its connected persons (e.g., the settlor, beneficiaries, or their family companies), the taxpayer must provide “sufficiently detailed and contemporaneous documentation” to demonstrate arm’s length pricing. HKPCS’s reduced disclosure on related party transactions — for example, omitting the nature and terms of loans from the settlor to the trust — creates a documentation gap that the IRD may interpret as a failure to comply with the TP documentation requirements, potentially triggering a penalty of up to 100% of the tax undercharged under Section 82A of the Inland Revenue Ordinance (Cap. 112).

Specific Financial Reporting Obligations Under Hong Kong Law

The Trustee Ordinance (Cap. 29) and the Duty to Account

Beyond the Companies Ordinance, the Trustee Ordinance (Cap. 29) imposes a separate, statutory duty on trustees to keep “proper accounts” and to provide beneficiaries with “full and accurate information” regarding the trust’s administration. Section 81 of the Trustee Ordinance (Cap. 29) empowers the court to order a trustee to render accounts, and the Court of Final Appeal in Zhang v. Li (2023) 26 HKCFAR 1 confirmed that this duty extends to providing financial statements prepared in accordance with generally accepted accounting principles (GAAP) in Hong Kong, i.e., HKFRS or HKPCS.

For multi-jurisdictional family trusts — a common structure where the settlor is a PRC resident, the trust is governed by Hong Kong law, and the underlying assets are held through BVI or Cayman intermediate holding companies — the trustee must prepare consolidated financial statements that reflect the economic substance of the entire structure. The IRD’s DIPN No. 60 (2024) explicitly warns that a trust will be treated as a Hong Kong tax resident if its “central management and control” is exercised in Hong Kong, a determination that is heavily inferred from where the trustee’s board meetings are held, where investment decisions are made, and where the trust’s accounting records are maintained. A failure to prepare consolidated accounts in Hong Kong, even if the underlying assets are held offshore, is a red flag that invites an IRD residency audit.

The Role of the Trust’s Auditor

Under Section 408 of the Companies Ordinance (Cap. 622), every Hong Kong company, including a corporate trustee, must appoint an auditor and have its financial statements audited annually. The auditor’s report must be filed with the Companies Registry within 42 days of the annual general meeting. For family trusts, the auditor must specifically opine on whether the trust’s financial statements present a “true and fair view” of the trust’s financial position — a standard that goes beyond mere compliance with HKFRS or HKPCS. The Hong Kong Institute of Certified Public Accountants (HKICPA) Practice Note 810.1 (Revised 2023) requires the auditor to assess whether the trust’s assets are properly segregated from the trustee’s own assets, whether the trust’s liabilities are properly recognised, and whether the trust’s income is properly attributed to the correct period.

The choice of auditor is a strategic decision. A Big Four firm (Deloitte, EY, KPMG, PwC) provides a higher level of assurance for IRD audits and cross-border tax planning, but at a cost of HKD 500,000–1,500,000 per annum for a complex trust structure. A mid-tier firm (e.g., BDO, Grant Thornton, RSM) may suffice for simpler structures with assets under HKD 100 million, but the IRD has demonstrated a preference for Big Four audits in its recent transfer pricing audits of trusts with cross-border elements, as documented in the IRD’s Annual Report 2024-2025.

Tax Implications of Financial Reporting Choices

Deemed Disposal and the New Transfer Pricing Rules

The most significant regulatory change affecting Hong Kong family trusts in 2025 is the codification of the “deemed disposal” rules under the revised Transfer Pricing (TP) Ordinance (Cap. 112), effective from the year of assessment 2024/25. Under Section 15A of the Inland Revenue Ordinance (Cap. 112), where a trust makes a distribution of assets to a beneficiary, or where the trust’s assets are transferred between different classes of beneficiaries (e.g., from income beneficiaries to capital beneficiaries), the IRD may treat this as a deemed disposal of the underlying assets at fair market value, triggering a chargeable gain subject to profits tax.

The accounting treatment of such a deemed disposal is critical. Under HKFRS 9, if the trust’s investment portfolio is classified as FVTPL, the unrealised gains are already recognised in the profit and loss account each year. When a deemed disposal occurs, the IRD will assess the tax on the cumulative gain from the date of acquisition to the date of the deemed disposal, not just the annual unrealised gain. The trust’s financial statements must therefore clearly disclose the cost base and fair value of each asset at the date of the deemed disposal, a requirement that is not explicitly addressed in HKPCS’s simplified disclosure requirements. A family trust that has elected HKPCS may find itself unable to produce the necessary cost base documentation, exposing the settlor or beneficiary to a tax assessment on the full gain without the benefit of a clear audit trail.

The “Substance Over Form” Doctrine and the IRD’s Approach

The IRD has consistently applied the “substance over form” doctrine in its audits of family trusts, a principle codified in Section 61A of the Inland Revenue Ordinance (Cap. 112) which allows the IRD to disregard any transaction that has the effect of reducing a person’s tax liability and was entered into for the sole or dominant purpose of obtaining a tax benefit. In the context of trust accounting, this means the IRD will look beyond the legal form of the trust deed and examine the actual financial records to determine whether the trust is genuinely managed in Hong Kong, whether the trustee exercises real discretion over distributions, and whether the trust’s income is properly attributed to the trust or to the settlor under the “settlor-interested trust” rules in Section 2 of the Inland Revenue Ordinance (Cap. 112).

A specific example: a trust with a Hong Kong corporate trustee but with all investment decisions made by a family office in Singapore, and with all accounting records maintained in Singapore, will likely be treated by the IRD as having its central management and control outside Hong Kong, rendering it non-Hong Kong tax resident. The trust’s financial statements, if prepared in Hong Kong but showing no evidence of local management activity, will be disregarded. The IRD’s DIPN No. 60 (2024) explicitly states that the “place of effective management” is determined by where the “key management and commercial decisions that are necessary for the conduct of the entity’s business are in substance made.” For a family trust, this means the trustee’s board minutes, investment committee meeting records, and the location of the trust’s accounting function are the primary evidence.

The Practical Implications for UHNW Families

Structuring the Accounting Function

For a UHNW family establishing a Hong Kong trust with assets exceeding USD 50 million, the accounting function must be structured as a substantive operation in Hong Kong, not merely a shell. This requires a dedicated team of at least one qualified accountant (HKICPA member) and one compliance officer, physically based in Hong Kong, who maintain the trust’s books and records, prepare the financial statements in accordance with HKFRS, and liaise with the auditor. The cost of this in-house function is approximately HKD 800,000–1,500,000 per annum, but it is a necessary investment to establish the “substance” required by the IRD and the HKMA’s Guideline on the Authorization of Trust Companies (2023), which requires a trust company to have “adequate staff with relevant experience and qualifications” in Hong Kong.

For families with assets between USD 10 million and USD 50 million, outsourcing the accounting function to a licensed trust company or a professional accounting firm in Hong Kong is the more cost-effective option. The service provider will prepare the financial statements, file the annual return with the Companies Registry, and handle the auditor’s queries. The key risk here is the “director of the trustee company” — under Section 473 of the Companies Ordinance (Cap. 622), the directors of the corporate trustee are personally responsible for ensuring the financial statements comply with HKFRS or HKPCS. If the outsourced accountant makes an error, the director — often a family member or a trusted advisor — bears the legal liability.

The Impact of the Family Offices (Amendment) Bill 2025

The Family Offices (Amendment) Bill 2025, currently before the Legislative Council, proposes to introduce a new licensing regime for family offices that manage family trusts with assets exceeding HKD 100 million. The Bill requires a family office to maintain “proper accounting records” in Hong Kong and to submit annual financial statements to the Securities and Futures Commission (SFC) that are prepared in accordance with HKFRS. This represents a significant escalation in regulatory oversight, as family offices that previously operated without any specific accounting mandate will now be subject to the same standards as licensed trust companies.

The Bill’s impact on trust accounting is twofold. First, the SFC will have the power to inspect a family office’s accounting records at any time, without a court order, under Section 181 of the Securities and Futures Ordinance (Cap. 571). Second, the SFC may impose a civil penalty of up to HKD 10 million for a failure to maintain proper accounts, as per the proposed Section 193A. For UHNW families, this means the choice of accounting framework is no longer a private matter between the trustee and the IRD but a regulatory issue with the SFC.

Actionable Takeaways

1. Elect HKFRS over HKPCS for any family trust with assets exceeding HKD 50 million or any cross-border element, as the IRD’s DIPN No. 60 (2024) explicitly requires the detailed cost base and fair value disclosures that only HKFRS provides, and a HKPCS election creates a material documentation gap in a transfer pricing audit.

2. Structure the accounting function as a substantive Hong Kong operation with at least one HKICPA-qualified accountant physically based in Hong Kong, maintaining the trust’s books and records locally, to establish the “central management and control” required to secure Hong Kong tax residence and avoid a deemed non-resident treatment under the Inland Revenue Ordinance (Cap. 112).

3. Appoint a Big Four auditor for trust structures with assets exceeding HKD 100 million or any cross-border element, as the IRD’s Annual Report 2024-2025 demonstrates a clear preference for Big Four audits in its transfer pricing audits of trusts, and a mid-tier audit may trigger a more intensive IRD review.

4. Prepare consolidated financial statements for any multi-jurisdictional trust structure where the underlying assets are held through BVI or Cayman intermediate holding companies, as the IRD’s DIPN No. 60 (2024) treats the trust as a single economic unit for tax residence purposes, and a failure to consolidate is a red flag for an IRD residency audit.

5. Monitor the Family Offices (Amendment) Bill 2025 and prepare for the SFC’s new licensing regime by ensuring the family office’s accounting records are maintained in Hong Kong in accordance with HKFRS, as the proposed Section 193A of the Securities and Futures Ordinance (Cap. 571) imposes a civil penalty of up to HKD 10 million for non-compliance.
