Tax Benefits of Charitable Donations in Estate Planning: Deduction Limits for Approved Charitable Gifts in Hong Kong

Hong Kong’s Inland Revenue Department (IRD) processed over HKD 9.6 billion in tax-deductible charitable donations for the Year of Assessment 2023/24, a figure that has risen steadily from HKD 8.3 billion five years prior. This upward trajectory, combined with the government’s 2024-25 Budget proposal to extend the enhanced deduction cap for approved charitable gifts through 2027, makes 2025 a pivotal year for estate planners. For high-net-worth families in Hong Kong, charitable giving is no longer merely a philanthropic gesture — it is a structurally efficient mechanism for reducing estate duty exposure (abolished since 2006 but still relevant for certain assets) and optimising profits tax liabilities under Section 16D of the Inland Revenue Ordinance (Cap. 112). The 2025-26 financial year presents a specific window: the current 35% cap on assessable profits for approved charitable donations, raised temporarily from 30% during the pandemic, remains in effect until 31 March 2027. Estate planners structuring wills or trusts for clients aged 50+ must now integrate these deduction limits into their inheritance strategies, or risk leaving significant tax relief unclaimed.

The Statutory Framework for Charitable Donations in Hong Kong

Section 16D of the Inland Revenue Ordinance: The Core Mechanism

The legal basis for tax-deductible charitable donations in Hong Kong is Section 16D of the Inland Revenue Ordinance (Cap. 112). This provision allows a deduction for donations of money (not property) to approved charitable institutions or trusts of a public character, provided the total donation in a given year of assessment does not exceed 35% of the donor’s assessable profits or income. For individuals, the deduction is capped at 35% of assessable income before the deduction; for corporations, it is 35% of assessable profits. The minimum donation per approved charity is HKD 100. The IRD maintains a publicly searchable list of approved charities under Section 88 of the same ordinance, which as of January 2025 numbered approximately 9,800 entities. Estate planners must verify the charity’s Section 88 status before advising any donation-linked inheritance structure.

The Temporary Enhanced Cap and Its Expiry Date

The 35% cap is not permanent. The Inland Revenue (Amendment) (Tax Deductions for Charitable Donations) Ordinance 2021 raised the cap from 30% to 35% for years of assessment 2021/22 through 2026/27. The 2024-25 Budget, delivered by Financial Secretary Paul Chan in February 2024, confirmed the cap would remain at 35% until 31 March 2027. After that date, unless further amended, the cap reverts to 30%. For a client with HKD 10 million in assessable profits, the difference between 35% and 30% is HKD 500,000 in potential deduction — a material sum that directly affects net estate value. Estate plans drafted in 2025 should incorporate this sunset clause, either by front-loading donations before the cap drops or by structuring multi-year pledges that fall within the enhanced window.

Approved Charities vs. Unapproved Entities: The Due Diligence Requirement

The IRD is rigorous on this point. Only donations to charities approved under Section 88 of the Inland Revenue Ordinance qualify for deduction. Donations to unregistered entities — including many overseas charities, religious organisations without Section 88 status, or local community groups — attract no tax relief. The IRD’s 2023 Annual Report noted that over HKD 1.2 billion in claimed deductions were disallowed in the prior three years due to non-compliance with Section 88 requirements. For estate planners, this means every charitable bequest or donation clause in a will must name the specific Section 88-approved entity. A generic clause such as “to a charitable organisation of my trustees’ choosing” risks IRD rejection unless the trustees select only approved charities.

Integrating Charitable Donations into Will and Trust Structures

Testamentary Charitable Gifts: The Deduction Timing Problem

A common estate planning technique is to include a charitable legacy in a will — for example, leaving HKD 5 million to a named hospital trust. The tax treatment of such gifts, however, differs from lifetime donations. Under Section 16D, the deduction is available only in the year of assessment in which the donation is made. For testamentary gifts, the donation occurs after death, when the deceased’s estate is being administered. The estate itself is not a taxpayer; rather, the executor or administrator files the deceased’s final tax return for the year of death. If the charitable gift is paid out in a subsequent year, it may not be deductible against the deceased’s final income. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 35 clarifies that a donation made by an executor after the date of death is not deductible against the deceased’s pre-death income. This creates a structural gap: the charitable bequest reduces the estate’s value for inheritance purposes but yields no income tax benefit. The solution is to convert testamentary gifts into lifetime donations via a charitable trust or a donor-advised fund, where the donor makes the gift while alive and claims the deduction against their own assessable profits.

Charitable Trusts and the HKSAR Trustee Ordinance

Hong Kong’s Trustee Ordinance (Cap. 29) permits the creation of charitable trusts, which are exempt from the rule against perpetuities and can exist indefinitely. A charitable trust structured during the settlor’s lifetime allows the donor to claim the Section 16D deduction in the year of contribution, while the trust continues to distribute to approved charities over time. For a client with HKD 50 million in assets, contributing HKD 17.5 million (35% of a notional HKD 50 million assessable profit) to a charitable trust in 2025 yields an immediate tax saving of up to HKD 2.975 million at the current 16.5% profits tax rate. The trust deed must specify that the trust is exclusively charitable and that all distributions go to Section 88-approved entities. The IRD’s 2022 guidance on charitable trusts (DIPN No. 47) emphasises that the trust itself must be registered as a charity under Section 88 to maintain the tax exemption on its income.

Donor-Advised Funds (DAFs): A Growing Hong Kong Structure

Donor-advised funds, while more common in the United States, are gaining traction in Hong Kong as a flexible vehicle for estate planning. A DAF is a fund held by a public charity (a Section 88 entity) into which the donor makes irrevocable contributions. The donor receives an immediate Section 16D deduction for the contribution, but retains advisory rights over how the fund distributes to other charities over time. As of 2025, the Hong Kong Jockey Club Charities Trust and the Community Chest of Hong Kong both operate DAF-style structures. For estate planners, the key advantage is that the donor can claim the full deduction in the year of contribution, even if the actual charitable distributions occur over a decade. This is particularly useful for clients with fluctuating income: they can contribute in a high-income year to maximise the deduction, then direct distributions in lower-income years. The IRD has not issued specific guidance on DAFs, but the prevailing practice, confirmed by tax counsel at three leading Hong Kong law firms in 2024, is that the deduction is valid provided the recipient fund is a Section 88 entity and the contribution is irrevocable.

Cross-Border Considerations and Jurisdictional Nuances

PRC Residents and Hong Kong Charitable Donations

For clients who are Hong Kong tax residents but hold assets in Mainland China, the interaction between Hong Kong and PRC tax regimes is critical. Under the PRC Individual Income Tax Law (2018 revision), charitable donations to approved PRC charities are deductible up to 30% of taxable income. However, a donation to a Hong Kong Section 88 charity does not qualify for PRC tax relief unless the charity is separately approved by the PRC Ministry of Finance and the State Taxation Administration. As of 2025, only a handful of Hong Kong charities — primarily the Hong Kong Red Cross and the Hong Kong Committee for UNICEF — hold such dual approval. For a client with PRC-source income, the estate plan should allocate charitable giving to the jurisdiction where the deduction is most valuable. A common structure is to make PRC donations from PRC income (30% deduction) and Hong Kong donations from Hong Kong income (35% deduction), avoiding double-counting.

The Cayman Islands Foundation and Hong Kong Deduction Arbitrage

High-net-worth families with assets held in Cayman Islands foundations or BVI trusts often seek to claim Hong Kong tax deductions for donations made from those offshore structures. The IRD’s position, stated in DIPN No. 35, is that the deduction is available only to the person who is the beneficial owner of the income against which the deduction is claimed. If a Cayman foundation makes a donation from its capital, and the Hong Kong resident beneficiary has no legal entitlement to that capital, no deduction arises in Hong Kong. The solution is to have the Hong Kong resident transfer personal funds to the offshore structure as a gift, then have the structure donate those funds — but this requires careful legal documentation to establish the donor’s beneficial ownership. The 2023 Hong Kong Court of Final Appeal decision in Commissioner of Inland Revenue v. Hang Seng Bank Trustee Ltd (2023) 25 HKCFAR 1 reinforced the principle that form must follow substance in charitable deduction claims.

US Persons and the Hong Kong Charity Trap

For US citizens or green card holders resident in Hong Kong, the US Internal Revenue Code Section 170 allows deductions for charitable contributions to US public charities, but not to foreign charities unless the foreign charity meets the “friends of” organisation test or the donor files Form 8283 with a qualified appraisal. A direct donation to a Hong Kong Section 88 charity by a US person yields no US tax benefit. However, the US-Hong Kong Double Taxation Agreement does not cover charitable deductions. Estate planners for US-Hong Kong dual residents must structure donations through a US public charity that then on-grants to the Hong Kong entity, or accept that the deduction is available only in Hong Kong. The 2024 US Treasury Circular 230 regulations impose additional documentation requirements for foreign charitable contributions exceeding USD 5,000.

Practical Implementation: Structuring the Deduction in a Will or Trust

Drafting the Charitable Clause: Specificity and IRD Compliance

Every will or trust deed containing a charitable gift must include the exact legal name and Section 88 reference number of the charity. A clause stating “I give HKD 2 million to The Community Chest of Hong Kong (Section 88 reference IR91/00015)” passes IRD scrutiny; a clause stating “to a charity of my executors’ choosing” does not. The IRD’s 2024 audit guidelines for charitable deductions (internal document, cited in the Law Society of Hong Kong’s 2024 Continuing Professional Development materials) indicate that the IRD cross-references every claimed deduction against its Section 88 register. Mismatches result in disallowance and potential penalties under Section 82A of the Inland Revenue Ordinance for incorrect returns. For clients with multiple charities, each must be individually named with its reference number.

The HKD 100 Minimum and Aggregate Donation Limits

Section 16D(2) requires that each donation to a single approved charity must be at least HKD 100. There is no upper limit per charity, but the aggregate deduction across all charities is capped at 35% of assessable profits or income. For a client with HKD 20 million in assessable profits, the maximum deductible donation is HKD 7 million. Any excess is carried forward? No — Hong Kong does not permit carry-forward of unused charitable donation deductions. The excess is simply lost. This makes precise planning essential. A client who donates HKD 10 million in a year with HKD 20 million in profits wastes HKD 3 million in potential deduction. The solution is to spread large donations across multiple years, staying within the 35% cap each year.

Executor’s Discretion and the Risk of Disallowance

A common drafting technique is to give the executor discretion to select charities. This creates a timing problem: the executor may not select the charities until after the tax return for the year of death is due. The IRD’s position, confirmed in the 2023 Board of Review decision D46/23, is that a deduction claimed on a return before the donation is actually made is invalid. The executor must either make the donation before filing the final return (which may be impractical if the estate is still being administered) or file an amended return after the donation is made. The latter approach is permissible under Section 70A of the Inland Revenue Ordinance but requires the executor to apply for an extension of the assessment. Estate planners should include a clause authorising the executor to make interim distributions to charities before the final estate accounts are settled, to ensure the donation timing aligns with the tax return filing.

Actionable Takeaways for Estate Planners

1. Verify the Section 88 status of every named charity in a will or trust deed before execution, and include the IRD reference number in the document to avoid disallowance on audit.
2. Structure charitable gifts as lifetime donations to a donor-advised fund or charitable trust rather than testamentary bequests, to capture the Section 16D deduction against the donor’s own assessable profits.
3. Front-load charitable contributions before 31 March 2027 to take advantage of the 35% cap, as the cap reverts to 30% after that date unless further extended by the Legislative Council.
4. For US-Hong Kong dual residents, route donations through a US public charity to preserve US tax deductibility, and document the on-granting structure with Form 8283 and a qualified appraisal.
5. Do not carry forward excess donations — Hong Kong law provides no carry-forward mechanism, so cap each year’s donations at 35% of that year’s assessable profits or income.
