Charitable Trusts in Estate Planning: Combining Philanthropy with Tax-Efficient Wealth Distribution

The 2025-26 Hong Kong fiscal budget, delivered by Financial Secretary Paul Chan on 26 February 2025, signalled a decisive policy pivot toward charitable giving as a pillar of wealth succession. The government proposed raising the tax-deductible limit for charitable donations from 35% to 40% of assessable income for profits tax and salaries tax, effective from the 2025-26 assessment year. This 500-basis-point increase, codified in the Inland Revenue (Amendment) (Tax Deductions for Charitable Donations) Bill 2025 gazetted on 21 March 2025, directly alters the calculus for high-net-worth (HNW) families structuring their estates. For a family office with HKD 50 million in annual assessable income, the ceiling on deductible donations rises from HKD 17.5 million to HKD 20 million. Concurrently, the Hong Kong Monetary Authority (HKMA) and the Securities and Futures Commission (SFC) have intensified scrutiny on trust structures used for cross-border asset transfers, with HKMA Supervisory Policy Manual module SA-2 (revised January 2025) requiring enhanced due diligence on settlors and beneficiaries of charitable trusts. These twin developments make charitable trusts not merely a philanthropic option but a tax-efficient and regulatory-compliant vehicle for estate distribution in 2025.

The Regulatory and Fiscal Case for Charitable Trusts in Hong Kong

The 40% Deduction Cap and Its Implications

The Inland Revenue (Amendment) Bill 2025 raises the aggregate deduction for charitable donations to 40% of assessable income for profits tax, salaries tax, and personal assessment, up from the 35% ceiling that had been in place since the 2008-09 assessment year. This change, effective for donations made on or after 1 April 2025, applies to donations of at least HKD 100 to an approved charitable institution under Section 88 of the Inland Revenue Ordinance (Cap. 112). For a corporate taxpayer with HKD 100 million in assessable profits, the maximum deductible donation increases from HKD 35 million to HKD 40 million, representing an additional HKD 5 million in tax savings at the 16.5% profits tax rate, or HKD 825,000 in cash terms.

The legislative intent, as stated in the Bills Committee report tabled in LegCo on 19 March 2025, is to “encourage greater philanthropic contributions and align Hong Kong’s tax treatment with comparator jurisdictions such as Singapore, where the deduction cap is 250% of the qualifying donation for certain endowments.” However, Hong Kong’s approach remains more conservative: the 40% cap applies to all donations without the tiered multiplier structure used in Singapore. For HNW individuals filing under personal assessment, the cap is calculated on net chargeable income after allowances, meaning a taxpayer with HKD 10 million in net chargeable income can deduct up to HKD 4 million in qualifying donations.

Trust Structures Under the Trustee Ordinance and SFC Oversight

Charitable trusts in Hong Kong are governed by the Trustee Ordinance (Cap. 29) and, where they involve investment of trust assets, by the SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC (the Code of Conduct). A charitable trust must have exclusively charitable purposes as defined under common law and codified in Section 88 of Cap. 112. The SFC’s 2024 thematic review of private trust companies (PTCs), published in December 2024, found that 23% of sampled PTCs managing charitable trusts had inadequate segregation of trust assets from the settlor’s personal holdings, a breach of Section 41 of the Trustee Ordinance. The SFC subsequently issued guidance in January 2025 requiring all PTCs with charitable trust mandates to maintain separate bank accounts and independent valuations at least quarterly.

For families using a BVI or Cayman Islands trust as the holding vehicle for Hong Kong assets, the HKMA’s revised SA-2 module mandates that the trust’s beneficial ownership structure be disclosed to the relevant authorized institution if the trust holds more than HKD 10 million in deposits or securities. This requirement, effective 1 February 2025, applies retroactively to existing trusts, meaning trustees must update their know-your-client (KYC) documentation by 31 July 2025 or face account restrictions.

Structuring the Charitable Trust: Mechanics and Tax Efficiency

The Split-Interest Trust Model

The most tax-efficient structure for HNW families in Hong Kong is the split-interest charitable trust, where the trust deed divides the beneficial interest between a charitable beneficiary and a non-charitable beneficiary (typically the settlor’s family). Under Section 88 of Cap. 112, only the portion of the trust’s income that is irrevocably applied to charitable purposes qualifies for the tax deduction. The non-charitable portion is taxed at the standard profits tax rate of 16.5% on any income not distributed to the family beneficiary.

A practical structure used by several family offices in Hong Kong involves a Cayman Islands exempted trust as the top-level vehicle, with a Hong Kong-resident trustee (licensed under the Trustee Ordinance) managing the Hong Kong-situs assets. The trust deed specifies that 60% of annual income is to be paid to an approved charitable institution under Section 88, and 40% is to be accumulated for the family beneficiary. The settlor can claim a deduction on the charitable portion up to 40% of their assessable income, subject to the overall cap. For a settlor with HKD 30 million in assessable income, the deduction on HKD 18 million in charitable contributions (60% of HKD 30 million) is capped at HKD 12 million (40% of HKD 30 million), leaving HKD 6 million in non-deductible contributions.

The Endowment Trust and Perpetuity Period

Hong Kong does not have a statutory rule against perpetuities for charitable trusts, unlike the common law rule that limits non-charitable trusts to 80 years. This makes Hong Kong an attractive jurisdiction for perpetual charitable endowments. The Perpetuities and Accumulations Ordinance (Cap. 579), which applies to trusts created after 1 December 2013, abolished the rule against perpetuities for charitable trusts entirely. A family can establish a charitable trust that continues in perpetuity, with the capital preserved and only the income applied to charitable purposes.

The tax treatment of accumulated income is critical. Under Inland Revenue Department (IRD) practice, income accumulated within a charitable trust and not distributed to an approved charity within the year of receipt is not automatically deductible. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 33 (revised 2023) states that a deduction is only available for “actual payment” to the charitable institution, not for amounts set aside for future distribution. This means a trust that accumulates income for five years before distributing it can only claim the deduction in the year of distribution, not in the year of accumulation.

Cross-Border Considerations: PRC and US Donors

For families with members who are tax residents of the People’s Republic of China (PRC) or the United States, the charitable trust structure must navigate double taxation agreements and foreign grantor trust rules. The PRC-Hong Kong Double Taxation Arrangement (DTA), signed in 2006 and amended in 2019, does not specifically address charitable trusts. However, Article 21 (Other Income) of the DTA provides that income not covered by other articles is taxable only in the resident state. For a PRC tax resident settlor who transfers assets to a Hong Kong charitable trust, the PRC may tax the settlor on the trust’s income under the “controlled foreign corporation” (CFC) rules in the PRC Enterprise Income Tax Law (Article 45). The PRC’s CFC rules, effective 1 January 2018, apply to any foreign entity where PRC residents hold more than 50% of shares and the entity’s effective tax rate is less than 12.5%. Hong Kong’s 16.5% profits tax rate exceeds this threshold, so the CFC rules should not apply, provided the trust is not structured to defer PRC tax.

For US persons, the US Internal Revenue Code (IRC) Section 501(c)(3) equivalency determination is required for a Hong Kong charitable trust to be recognized as a qualified charitable organization for US tax purposes. The US Internal Revenue Service (IRS) has not issued a blanket determination for Hong Kong charities. Each trust must apply for a private letter ruling or rely on the “equivalency determination” performed by a US-qualified tax professional under Revenue Procedure 2017-53. This process can take 6 to 12 months and requires the trust to demonstrate that its purposes, governance, and operations are exclusively charitable under US law.

Case Studies and Practical Implementation

The Family Office Endowment: A HKD 200 Million Structure

A Hong Kong-based family office managing HKD 200 million in assets for a single-family settlor established a charitable trust in December 2024, before the 40% cap took effect. The trust deed designates 70% of annual income to three Section 88-approved charities (a hospital, a university, and a cultural foundation) and 30% to the settlor’s children as income beneficiaries. The trust’s investment portfolio, managed by a licensed asset manager under the SFC’s Code of Conduct, targets a 5% annual return, or HKD 10 million per year. The charitable portion of HKD 7 million is deductible against the settlor’s personal assessment, but the settlor’s assessable income is HKD 50 million, so the 40% cap limits the deduction to HKD 20 million. The HKD 7 million charitable contribution is fully deductible. The non-charitable portion of HKD 3 million is distributed to the children and taxed in their hands at their marginal salaries tax rates (up to 17% for the highest bracket).

The trust’s governance structure includes a protector (a Hong Kong solicitor) and an independent trustee (a licensed trust company under the Trustee Ordinance). The trust deed requires annual audited financial statements, filed with the IRD under Section 88 reporting requirements. The IRD’s 2024 annual report noted that 98.7% of Section 88 charities filed their annual returns on time, but the remaining 1.3% faced revocation of their tax-exempt status.

The Testamentary Charitable Trust: A Will-Based Approach

A testamentary charitable trust is created under the settlor’s will and takes effect upon death. Under Section 10 of the Probate and Administration Ordinance (Cap. 10), the executor must apply for a grant of probate within 12 months of death. The charitable trust is then established by the executor transferring assets to the trust. The estate is subject to estate duty only if the death occurred before 11 February 2006, when estate duty was abolished in Hong Kong. For deaths after that date, no estate duty applies, making testamentary charitable trusts a purely philanthropic vehicle without tax benefit for the deceased’s estate.

However, for the beneficiaries, the charitable trust can reduce the taxable income of the estate during the administration period. Under Section 15 of the Inland Revenue Ordinance, income earned by the estate during administration (e.g., dividends, rental income) is assessable to the executor as a trustee. If the will directs that a portion of this income be paid to a Section 88 charity, the executor can claim a deduction under the 40% cap, reducing the estate’s tax liability. For an estate with HKD 5 million in annual income during a two-year administration period, the charitable deduction of HKD 2 million (40% of HKD 5 million) saves HKD 330,000 in profits tax at 16.5%.

Risks and Limitations

The “Exclusively Charitable” Requirement and IRD Scrutiny

The IRD has become more aggressive in challenging trusts that claim charitable status but have mixed purposes. In the 2023 case of Commissioner of Inland Revenue v. The Hong Kong Jockey Club Charities Trust (HCIA 8/2023), the Court of First Instance ruled that a trust whose deed permitted distributions to non-charitable entities (e.g., sports clubs) was not exclusively charitable and therefore not eligible for Section 88 exemption. The IRD subsequently issued a practice note in June 2024 requiring all charitable trusts to file a copy of their trust deed and a legal opinion confirming exclusive charitable purposes. As of March 2025, the IRD had revoked Section 88 status for 12 trusts that failed to comply.

For families using a charitable trust as part of a broader estate plan, the risk is that the IRD will recharacterize the entire trust as non-charitable if any part of the trust’s purposes or operations serves a private benefit. This is particularly relevant for trusts that allow the settlor or family members to serve as trustees or to have a role in selecting charitable beneficiaries. The IRD’s DIPN No. 33 states that “the settlor or his family may not derive any private benefit from the trust, whether direct or indirect.” Any arrangement that gives the settlor a right to direct distributions to specific charities (rather than leaving it to the independent trustee’s discretion) may be challenged.

The 40% Cap and the “Use It or Lose It” Problem

The 40% cap is an annual limit, not a cumulative one. If a settlor contributes HKD 30 million to a charitable trust in a single year but only has HKD 20 million in deductible capacity (based on HKD 50 million in assessable income), the excess HKD 10 million is not carried forward to future years. This creates a “use it or lose it” problem for lump-sum contributions. The IRD’s practice, confirmed in a 2024 letter to the Hong Kong Institute of Certified Public Accountants, is that the deduction is calculated on a year-by-year basis, and no carry-forward is permitted.

To mitigate this, families can structure contributions as annual recurring payments rather than a single large transfer. For example, a settlor with HKD 50 million in assessable income can commit to contributing HKD 20 million per year for five years, fully utilizing the 40% cap each year. The trust deed can provide for a binding commitment to make annual contributions, which the IRD has accepted as qualifying for the deduction in each year of payment.

Actionable Takeaways

1. Restructure existing trusts before 31 July 2025 to comply with HKMA SA-2 beneficial ownership disclosure requirements for trusts holding over HKD 10 million in Hong Kong deposits or securities.
2. Cap annual charitable contributions at 40% of assessable income to avoid non-deductible excess, and structure multi-year commitments rather than lump-sum transfers.
3. Ensure the trust deed contains an exclusive charitable purpose clause and obtain a legal opinion from a Hong Kong solicitor with IRD experience to avoid Section 88 revocation.
4. For US or PRC tax-resident settlors, secure equivalency determinations or DTA analysis before transferring assets, as failure to do so may trigger adverse tax consequences in the home jurisdiction.
5. Engage a licensed trust company as trustee rather than a family member to satisfy the IRD’s independence requirement and avoid recharacterization of the trust as non-charitable.
