Jurisdiction Change Tax for Family Trusts: Tax Transition Arrangements for Migrating a Trust to Hong Kong

The number of family offices and high-net-worth individuals (HNWIs) relocating trust structures to Hong Kong has risen sharply since the 2024/25 Hong Kong Budget introduced enhanced tax concessions for family-owned investment holding vehicles (FIHVs), effective from the 2022/23 year of assessment. Concurrently, jurisdictions like the United Kingdom (with its Non-Domicile regime reforms effective April 2025) and Singapore (with its Section 13O/13U variable capital company requirements tightening) are prompting a reassessment of trust situs. For a trust migrating its administration and central management and control (CMC) to Hong Kong, the critical tax issue is not merely the ongoing tax treatment but the exit tax or deemed disposal triggered by the change in jurisdiction of the trustees and the trust’s tax residence. This article examines the three-layer tax consequences of such a migration for the trust, the settlor, and the beneficiaries, focusing on the transitional provisions and anti-avoidance rules under the Inland Revenue Ordinance (Cap. 112) and relevant foreign statutes.

The Mechanics of Trust Migration and Hong Kong’s Territorial Source Principle

The operative tax position for a trust migrating to Hong Kong is that the move itself does not automatically trigger a Hong Kong tax liability. Hong Kong’s territorial source principle (Inland Revenue Ordinance, Cap. 112, Section 14 for profits tax) taxes only profits sourced in Hong Kong. For a trust, this means that a change in the location of the trust’s CMC—from, say, London to Hong Kong—only subjects future Hong Kong-source income to tax. However, the migration event itself is a disposal for capital gains tax purposes in the departing jurisdiction (e.g., the UK or Canada), and the trust’s assets may be deemed sold at market value.

Deemed Disposal in the Departing Jurisdiction

The primary tax cost of migration is the exit charge imposed by the trust’s former tax residence. For a trust previously resident in the United Kingdom, a change in the trustees’ residence to Hong Kong triggers a deemed disposal of all trust assets under TCGA 1992, Section 80. This applies where the trustees cease to be resident in the UK, regardless of whether the beneficiaries remain UK resident. The deemed disposal is at market value, and the resulting capital gains tax (CGT) is charged at 20% (for most assets) or 28% (for residential property) for the 2024/25 tax year. The trust has a window of up to six months to make an election to defer the tax under TCGA 1992, Section 80(5), but only if the trust continues to hold assets that would be chargeable to UK tax. This election is not available if the trust becomes resident in a jurisdiction with which the UK has no double taxation agreement (DTA) for capital gains—Hong Kong’s DTA with the UK (Art. 13) generally preserves the UK’s taxing rights over gains on UK-situs assets, meaning the deferral is often unavailable.

For a trust migrating from Singapore, the exit tax is less direct. Singapore does not impose a general capital gains tax. However, a trust that has claimed the Section 13O or 13U tax incentive scheme must be wound up or its assets transferred out of the Singapore variable capital company (VCC) structure. The transfer out of a VCC is treated as a disposal for Singapore income tax purposes, and any gains on assets held for trading or that are revenue in nature (e.g., from a property trading business) are taxed at the prevailing corporate rate of 17%. The Singapore Economic Development Board (EDB) requires a full audit of the trust’s compliance with the incentive conditions for the preceding five years before granting a certificate of non-objection to the migration.

Hong Kong’s Stance on Pre-Migration Gains

Hong Kong does not tax gains that accrued before the trust became resident. The Inland Revenue Department (IRD) has confirmed in Departmental Interpretation and Practice Notes (DIPN) No. 48 (Profits Tax) that a change in the situs of a business does not create a taxable event for profits that arose outside Hong Kong. For a trust, this means that unrealised capital gains on assets held at the date of migration are not subject to Hong Kong profits tax when later realised, provided those gains are not derived from a trade, profession, or business carried on in Hong Kong. The IRD’s focus is on the source of the realised gain, not the date of acquisition. A family trust that migrates to Hong Kong with a portfolio of US equities held for long-term appreciation will not face Hong Kong tax on the eventual sale, as the gain is capital in nature and not sourced in Hong Kong (CIR v. Hang Seng Bank [1991] 1 HKRC 90-086).

The Trust as a Separate Entity: Tax Residence and CMC

A trust is not a legal person, but for Hong Kong tax purposes, the trust’s tax residence follows the residence of its trustees. Under the IRD’s practice, a trust is considered resident in Hong Kong if the majority of its trustees are resident in Hong Kong and its central management and control is exercised in Hong Kong. This is a factual test, not a formal one.

Proving CMC in Hong Kong

To establish that the trust’s CMC is in Hong Kong, the trustees must demonstrate that all strategic decisions—investment policy, distribution decisions, appointment and retirement of trustees—are made at board meetings held in Hong Kong. The IRD will examine the minutes of trustee meetings, the location of the trust’s professional advisors (e.g., the family office), and the physical presence of the trustees. A common pitfall is the “rubber stamp” arrangement, where a Hong Kong trustee merely executes decisions made by a foreign protector or investment committee. The Hong Kong Court of Final Appeal in Commissioner of Inland Revenue v. Industrial Equity (Pacific) Ltd (2002) 5 HKCFAR 27 held that the place where the board of directors (or, by analogy, trustees) meets and makes decisions is the location of CMC. For a migrating trust, the first trustee meeting held in Hong Kong should be a substantive one, with a clear agenda and recorded resolutions, to establish the new CMC from that date.

The “Offshore” Profits Claim

A trust that is Hong Kong-resident is still only taxable on Hong Kong-source income. This means the trust can file profits tax returns claiming that its investment income (e.g., dividends from a BVI holding company, interest from a Swiss bank account) is offshore-sourced and thus not subject to Hong Kong profits tax. The IRD’s DIPN No. 21 (Revised 2020) provides guidance on the source of income for offshore claims. For a trust, the key factor is where the contracts for the investments were negotiated and executed and where the investment decisions were made. If the trust’s investment manager is in London and all trades are executed on the London Stock Exchange, the profits are likely offshore and not taxable in Hong Kong, even if the trust is resident here. The trust must maintain a full audit trail of all investment decisions, including emails, meeting notes, and trade confirmations, to support an offshore claim. The IRD’s examination cycle for offshore claims can extend to six years (Section 82A, Cap. 112), and the burden of proof is on the taxpayer.

The Settlor and Beneficiary Layer: Attribution and Remittance

The migration of a trust does not only affect the trust itself; it has profound implications for the settlor and beneficiaries, particularly those who are US persons or UK residents.

The Settlor’s Exit Tax

If the settlor is a US citizen or green card holder, the migration of the trust may trigger an exit tax under IRC § 877A. This applies where the settlor is a “covered expatriate” (i.e., has a net worth of USD 2 million or more on the date of expatriation or an average annual net income tax liability of more than USD 201,000 for the five years ending before the date of expatriation, as adjusted for 2025). The trust’s migration is not itself the trigger; rather, the settlor’s own change of residence (e.g., moving from the US to Hong Kong) is. However, if the trust is a grantor trust for US tax purposes, the settlor is treated as the owner of the trust assets, and the deemed sale of assets on expatriation includes the trust’s assets. The IRC § 877A(a)(1) imposes a mark-to-market tax on all of the expatriate’s worldwide assets as if sold on the day before the expatriation date, with an exclusion of USD 866,000 (2025) for capital gains. This is a hard tax cost that cannot be avoided by migrating the trust first; the US taxing jurisdiction over the settlor is personal, not entity-based.

For a UK-domiciled settlor, the trust’s migration to Hong Kong may trigger a charge under the UK’s Transfer of Assets Abroad provisions (ITA 2007, Part 13). If the settlor has retained an interest in the trust (e.g., as a beneficiary or as a person who can direct the trustees), the trust’s income and gains may be attributed back to the settlor under Section 720 ITA 2007. This attribution applies even after the trust has left the UK, provided the settlor remains UK resident. The UK’s new “residence-based” system for non-doms (effective April 2025) removes the remittance basis for new arrivals, but for existing trusts, the attribution rules remain in place. The settlor must file a UK tax return each year, disclosing the trust’s worldwide income and gains, and pay tax at UK rates (45% for income, 20% for gains) on the attributed amounts.

The Beneficiary’s Remittance Base

For a Hong Kong-resident beneficiary who is not a US person, the receipt of a distribution from the trust is not subject to Hong Kong salaries tax (as it is a capital receipt) and is not subject to profits tax (as the trust is not trading). The beneficiary’s tax position is straightforward: no Hong Kong tax on trust distributions.

For a US person beneficiary (citizen or green card holder) living in Hong Kong, the situation is reversed. The trust is a foreign trust for US tax purposes (IRC § 7701(a)(31)(B)). The beneficiary is subject to US tax on the trust’s accumulated income under the “throwback rule” (IRC § 665-668). This rule applies to distributions of “accumulated income” (i.e., income earned by the trust in prior years that was not distributed). The throwback tax is calculated by “throwing back” the distribution to the year the income was earned and applying the beneficiary’s marginal rate for that year, plus an interest charge (IRC § 6621(a)(2)). For a trust migrating to Hong Kong, the key issue is that the trust’s pre-migration income (e.g., UK-source dividends earned when the trust was UK-resident) is “foreign trust income” for US purposes. When that income is later distributed to a US beneficiary in Hong Kong, the throwback rule applies, and the beneficiary must file Form 3520 (Annual Return to Report Transactions with Foreign Trusts) and Form 3520-A (Annual Information Return of Foreign Trust with a US Owner). The penalty for failure to file Form 3520 is the greater of USD 10,000 or 35% of the gross value of the property transferred (IRC § 6677). This is a strict liability penalty; the IRS does not require proof of intent.

Structuring the Migration: The BVI/Hong Kong Holding Company Layer

A common structure for family trusts migrating to Hong Kong is to hold assets through a BVI or Cayman Islands company, which is in turn held by the trust. This adds a layer of complexity, as the migration of the trust’s CMC to Hong Kong may inadvertently make the BVI company Hong Kong-resident for tax purposes, and therefore subject to Hong Kong profits tax on its worldwide profits.

The Risk of “Dual Residence”

Under Article 4 of the US-HK Tax Information Exchange Agreement (TIEA), a company is resident in the jurisdiction where its place of effective management (POEM) is situated. The OECD Model Tax Convention (Art. 4(3)) also uses the POEM test. If the trust’s trustees, who control the BVI company’s board, are now in Hong Kong and making decisions there, the BVI company’s POEM may shift from the BVI to Hong Kong. This would make the BVI company Hong Kong-resident for profits tax purposes, and its worldwide profits (including dividends from subsidiaries, interest income, and capital gains) would be subject to Hong Kong profits tax at 16.5%. The BVI company would also lose its BVI tax residence status, as the BVI’s Economic Substance Act (2018) requires a company to have its CMC in the BVI to claim BVI tax residence. The result is a “dual non-resident” company—taxable in Hong Kong but not in the BVI—with no treaty protection.

To avoid this, the trust must ensure that the BVI company’s board meetings are held in the BVI (or a jurisdiction with a DTA with Hong Kong, such as Singapore) and that the directors are not the same individuals as the Hong Kong trustees. The trust’s constitutional documents should specify that the BVI company’s CMC is in the BVI, and the trust’s investment management agreement should delegate investment decisions to a separate Hong Kong family office, not to the BVI company’s board. This creates a clear separation between the trust’s CMC (Hong Kong) and the BVI company’s CMC (BVI).

The Hong Kong Family Office as a Tax-Exempt Vehicle

The 2024/25 Budget introduced a new tax concession for FIHVs (Section 20AN, Cap. 112). A family office that is a “family-owned investment holding vehicle” can elect to be exempt from profits tax on its qualifying investment income (including dividends, interest, and capital gains from securities and futures contracts) if it meets the following conditions:

• It is a private company incorporated in Hong Kong or a foreign company registered in Hong Kong.
• It is wholly owned by one or more family members (up to 25 individuals).
• Its assets under management are at least HKD 2.4 billion (USD 307 million).
• It employs at least two full-time qualified investment professionals in Hong Kong.
• Its annual operating expenditure in Hong Kong is at least HKD 3 million.

For a trust migrating to Hong Kong, the FIHV exemption is a powerful tool. The trust can transfer its assets to a Hong Kong-incorporated FIHV, which then holds the BVI company. The FIHV’s investment income is exempt from Hong Kong profits tax, and the trust’s distributions to beneficiaries are not subject to Hong Kong tax. The key requirement is that the FIHV must be “family-owned”—i.e., the trust must be the sole shareholder, and the beneficiaries must be family members. This structure effectively eliminates the Hong Kong tax layer on the trust’s investment income, leaving only the US or UK tax on the beneficiaries, which is unavoidable.

Actionable Takeaways

1. Pre-migration audit: Before migrating a trust to Hong Kong, obtain a professional valuation of all trust assets and compute the deemed disposal tax in the departing jurisdiction (UK CGT at 20-28% or US exit tax under IRC § 877A) to determine the cash cost of the move.
2. Document CMC from day one: Hold the first substantive trustee meeting in Hong Kong with a formal agenda, recorded minutes, and resolutions that demonstrate the trust’s central management and control is now in Hong Kong; retain all records for at least seven years.
3. Separate the BVI company’s CMC: Ensure the BVI company’s board meetings are held outside Hong Kong (e.g., in the BVI or Singapore) and that its directors are not the Hong Kong trustees, to avoid the BVI company becoming Hong Kong-resident for profits tax.
4. File US Forms 3520 and 3520-A annually: For any US person beneficiary, file these forms with the IRS by April 15 (or October 15 with extension) each year, even if no distribution is received, to avoid the 35% penalty under IRC § 6677.
5. Consider the FIHV election: If the trust’s assets under management exceed HKD 2.4 billion, incorporate a Hong Kong family-owned investment holding vehicle (FIHV) to hold the trust’s assets and claim the profits tax exemption under Section 20AN, Cap. 112.
