How to Set Up Charitable Remainder Trusts: Combining Tax Optimisation and Philanthropy

Hong Kong’s Inland Revenue Department (IRD) issued Departmental Interpretation and Practice Notes (DIPN) No. 59 in December 2024, clarifying the tax treatment of charitable trusts and donations under the Inland Revenue Ordinance (IRO) Cap. 112. This represents the most significant regulatory guidance on philanthropic structures in over a decade, directly impacting the viability of Charitable Remainder Trusts (CRTs) for high-net-worth (HNW) individuals domiciled in or with assets in Hong Kong. For family offices and private trust clients, the intersection of tax optimisation under Sections 16D and 26C of the IRO and the structural flexibility of CRTs now presents a calibrated opportunity to reduce estate duty exposure—abolished in Hong Kong since 2006 but still relevant for cross-border assets—while securing a perpetual philanthropic legacy. This article dissects the mechanics of establishing a CRT in Hong Kong, integrating VISTA and STAR trust frameworks where applicable, and navigates the precise regulatory and tax compliance requirements for HNW principals and their advisors.

The Regulatory and Tax Foundation for CRTs in Hong Kong

The 2024 DIPN No. 59 explicitly addresses the deductibility of donations made through trusts, including those structured with a remainder interest. Under Section 16D of the IRO, aggregate deductible charitable donations in a year of assessment are capped at 35% of assessable income, a threshold unchanged since the 2018-19 budget but now clarified for trust structures. For a CRT, the donor receives an immediate tax deduction for the present value of the charitable remainder interest, not the full corpus, a calculation that requires actuarial valuation under IRD-approved mortality tables.

The Mechanics of Charitable Remainder Trusts Under Hong Kong Law

A Charitable Remainder Trust is an irrevocable trust structure where the settlor (or named non-charitable beneficiaries) receives an income stream for a defined term or for life, with the remainder passing to a registered charity under Section 88 of the IRO. The IRD’s 2024 guidance confirms that for a CRT to qualify for deduction, the charitable beneficiary must be an approved charity under Section 88, and the trust deed must specify that no part of the income or corpus can revert to the settlor or any non-charitable beneficiary after the term. The HKEX Listing Rules are not directly applicable here, but for HNW clients with listed shares, the transfer of securities into a CRT must comply with the SFC’s Code on Unit Trusts and Mutual Funds (Cap. 571) if the trust holds more than 5% of a listed company’s issued shares.

Cross-Border Considerations and Double Taxation Agreements

Hong Kong’s network of Double Taxation Agreements (DTAs), now numbering over 45 including the 2024 protocol with the UAE, affects CRT structures where the settlor is a tax resident of another jurisdiction. The IRD’s DIPN No. 59 clarifies that deductions for donations to Hong Kong Section 88 charities are only available against Hong Kong-sourced income. For HNW individuals with assets in BVI, Cayman, or Bermuda, the CRT must be established as a separate trust under Hong Kong law to claim deductions; a VISTA trust in BVI cannot itself be the CRT vehicle for Hong Kong tax purposes. The 2024 case of Commissioner of Inland Revenue v. HSBC International Trustee Limited (HCIA 12/2023) affirmed that the IRD will look through trust structures to the underlying economic substance, requiring that the charitable remainder is legally and irrevocably committed.

Structuring the CRT: VISTA, STAR, and Hong Kong Trust Options

For HNW clients, the choice of trust jurisdiction determines the degree of control over underlying assets and the tax efficiency of the income stream. Hong Kong trusts, governed by the Trustee Ordinance (Cap. 29), offer no capital gains tax and no withholding tax on dividends, making them the default for CRTs holding Hong Kong equities or property. However, for clients seeking to retain investment control—a common requirement for family offices—the BVI VISTA trust or Cayman STAR trust provides a statutory override of the trustee’s duty to intervene in underlying company management.

Hong Kong Trusts: Simplicity and Tax Alignment

A Hong Kong-incorporated CRT under the Trustee Ordinance requires a licensed trust company, typically registered with the Hong Kong Monetary Authority (HKMA) under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO) Cap. 615. The trust deed must specify the income distribution frequency—quarterly or semi-annual is standard—and the charitable remainder must be a named Section 88 charity. As of 2025, the IRD accepts actuarial valuations from the Hong Kong Institute of Actuaries for the charitable deduction calculation, with the deduction capped at 35% of the settlor’s assessable income per year of assessment.

BVI VISTA Trusts: Retaining Control of Operating Companies

The Virgin Islands Special Trusts Act (VISTA), as amended in 2023, allows a CRT settlor to retain control of a BVI business company (BC) held in the trust, without the trustee being required to intervene in management. For a CRT, this means the settlor can continue to manage a family operating company while the trust holds the shares, with dividends paid to the income beneficiary and the shares ultimately passing to a Hong Kong Section 88 charity. The BVI Financial Services Commission’s 2024 guidance on VISTA trusts confirms that the charitable remainder must be a recognised charity under the BVI Charities Act, but for Hong Kong tax deduction purposes, the charity must also be registered under Section 88 of the IRO. This dual registration requirement adds administrative cost but is feasible for large endowments exceeding HKD 50 million.

Cayman STAR Trusts: Flexibility for Multiple Charitable Purposes

The Cayman Islands Special Trusts (Alternative Regime) Law (STAR), effective since 1997 and updated in 2022, permits a trust with both charitable and non-charitable purposes, and allows the appointment of an enforcer to ensure the charitable objects are fulfilled. For a CRT, STAR trusts are attractive for HNW clients with multi-jurisdictional families, as the trust can hold assets in Cayman, Hong Kong, and Singapore simultaneously. The Cayman Monetary Authority’s 2023 circular on STAR trusts requires that the charitable remainder be specifically identified in the trust deed, and the enforcer must be a Cayman-resident individual or entity. For Hong Kong tax purposes, the IRD will only recognise the charitable deduction if the trust deed explicitly states that the Cayman charity will transfer the assets to a Hong Kong Section 88 charity upon vesting, a structure that requires careful cross-border legal advice.

Tax Optimisation: Income Streams, Deductions, and Estate Planning

The primary tax benefit of a CRT in Hong Kong is the immediate deduction for the charitable remainder value, combined with the ability to defer capital gains tax on appreciated assets—though Hong Kong has no capital gains tax, this matters for clients with assets in jurisdictions that do, such as the UK or US. For a Hong Kong-domiciled CRT, the income paid to the settlor is subject to profits tax only if the trust is carrying on a trade or business in Hong Kong, which is rare for a passive income trust.

Maximising the 35% Deduction Cap

Under Section 26C of the IRO, aggregate charitable donations in a year of assessment are deductible up to 35% of assessable income, with any excess carried forward for up to five years. For a CRT, the deduction is the actuarial present value of the charitable remainder, not the annual income stream. As an example, a HKD 100 million CRT with a 10-year term and a 5% annual payout to the settlor would have a charitable remainder value of approximately HKD 61.4 million, using a 3% discount rate per IRD-approved tables. This yields a maximum deduction of HKD 21.5 million per year for a settlor with assessable income of HKD 61.4 million or more, spread over the deduction period.

Estate Planning for Cross-Border Assets

For HNW individuals with assets in jurisdictions that still impose estate or inheritance taxes—such as the UK at 40% above the GBP 325,000 nil-rate band, or the US at 40% above the USD 13.61 million exemption (2024 figure, set to revert to USD 5 million in 2026 under the Tax Cuts and Jobs Act sunset)—a CRT removes the assets from the settlor’s personal estate. The Hong Kong IRD does not impose estate duty, but the HKMA’s 2023 circular on trust structures for cross-border wealth management requires that any trust with assets in multiple jurisdictions must comply with the reporting requirements of each jurisdiction’s tax authority. For a CRT holding UK real estate, the trust must register with HM Revenue & Customs under the Trust Registration Service (TRS), with penalties of up to GBP 5,000 for non-compliance as of 2025.

Philanthropy and Legacy: Selecting the Charitable Remainder

The choice of charitable remainder is the most critical structural decision, as it determines both the tax deduction and the philanthropic impact. Hong Kong has over 9,000 Section 88 charities as of 2025, but only 150-200 have the institutional capacity to accept large trust remainders exceeding HKD 10 million. The IRD’s 2024 DIPN No. 59 requires that the charity must be approved at the time the trust is established, not at the vesting date, to claim the deduction.

University and Research Endowments

The University of Hong Kong, Chinese University of Hong Kong, and Hong Kong University of Science and Technology each have dedicated trust offices for accepting charitable remainders, with minimum endowments typically set at HKD 5 million. These institutions are registered under Section 88 and have established procedures for actuarial valuation and receipt issuance. The IRD’s 2024 guidance confirms that a CRT remainder to a university endowment qualifies for the full deduction, provided the trust deed specifies the purpose—for example, a scholarship fund or research chair.

Community Foundations and Donor-Advised Funds

The Hong Kong Jockey Club Charities Trust and the Community Chest of Hong Kong are the largest institutional recipients of charitable remainders, with the Jockey Club managing over HKD 4.5 billion in charitable assets as of 2024. For HNW clients who want flexibility in the ultimate distribution of the remainder, a donor-advised fund (DAF) held by a Section 88 charity can serve as the remainder beneficiary, allowing the settlor’s family to recommend grants over time. The SFC’s 2023 guidelines on DAFs require that the charity retains legal control over the funds, and the trust deed must state that the DAF is irrevocable.

Actionable Takeaways

• Establish the CRT under Hong Kong law with a Section 88 charity as the named remainder to claim the 35% deduction under Section 16D of the IRO, using an actuarial valuation from a Hong Kong Institute of Actuaries member.
• For clients retaining control of operating companies, use a BVI VISTA trust for the underlying company shares, but ensure the charitable remainder is a Hong Kong Section 88 charity to satisfy IRD requirements under DIPN No. 59.
• Structure the income stream to avoid profits tax by ensuring the trust holds passive assets only, with no active trading in Hong Kong, as confirmed by the CIR v. HSBC International Trustee (2023) precedent.
• For cross-border assets, register the trust with relevant tax authorities—such as HMRC’s TRS for UK property—and verify that the DTA with the asset’s jurisdiction does not override the Hong Kong deduction.
• Select a charitable remainder with institutional capacity to accept large endowments, such as a university or the Hong Kong Jockey Club Charities Trust, and specify the philanthropic purpose in the trust deed to avoid future disputes.
