The United Kingdom-to-Hong Kong family-office UK guide

The United Kingdom's combined shift on non-domiciled resident (non-dom) taxation – the abolition of the remittance basis and the move toward a residence-based system – has focused the minds of a generation of wealth principals. For many who hold international assets and run a family office with a real cross-border footprint, the question is no longer whether to restructure. It is where to go and, critically, in what sequence.

A United Kingdom-to-Hong Kong family-office relocation requires a defined sequence of steps across two common-law systems: ending United Kingdom tax residence on terms that satisfy the Statutory Residence Test, shifting the management-and-control function of any holding entities, and establishing substantive operational presence in Hong Kong before the first Hong Kong tax year closes. The governing instruments include the Inland Revenue Ordinance (Hong Kong) on the territorial-source side and the United Kingdom's statutory regime on the exit side. The sequence decides the outcome.

This guide sets out the steps in order, the gate at each stage, and the structural mistakes that most frequently derail a well-intentioned move. It is written for in-house counsel, family-office principals and their advisers managing the transition from the United Kingdom to Hong Kong.

Why Hong Kong? Placing the decision in its cross-border context

Hong Kong operates on a territorial basis. Under the Inland Revenue Ordinance, profits tax applies only to profits arising in or derived from Hong Kong. There is no capital gains tax. There is no withholding tax on dividends or interest. The two-tier profits tax rate applies at 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that, which is a straightforward position for a family office with investment-holding or management functions.

For a principal exiting the United Kingdom after years of remittance-basis treatment, the contrast is material. The United Kingdom imposes income tax, capital gains tax, and – for those with a United Kingdom domicile or deemed domicile – inheritance tax on a worldwide basis. Hong Kong imposes none of the above on offshore capital gains or foreign-sourced income in the ordinary position.

The cross-border interface is also friendly in a structural sense. Both Hong Kong and the United Kingdom are common-law jurisdictions. Trust law, corporate governance, and contractual instruments travel reasonably well between the two systems. A trustee structure established under English law can be restated or re-governed under the Trustee Ordinance (Cap. 29) of Hong Kong without the discontinuity one might encounter moving to a civil-law centre.

There is a Hong Kong–United Kingdom tax treaty in place. Parties should verify the current scope and operation of that treaty before acting, as treaty positions interact with both the territorial-source rules in Hong Kong and the United Kingdom's exit and ongoing charge provisions. Our desk regularly maps the treaty interface as part of the pre-move diagnostic.

The Family Office incentive policies introduced as part of Hong Kong's asset-management and wealth hub development provide a further structural pull. In our cross-border practice, we see principals from the United Kingdom, continental Europe and the Middle East assessing Hong Kong against Singapore as the two principal common-law, low-tax, Asian hubs. The United Kingdom-to-Hong Kong route carries its own sequencing requirements that differ from the European-to-Singapore or Middle East-to-Hong Kong paths.

Step 1 – Pre-move diagnostic: mapping the United Kingdom exposure before anything moves

The first step is a full pre-move diagnostic: a mapped picture of the United Kingdom tax exposure, the holding structure, the trust and fiduciary positions, and the employment or office-holding arrangements that create United Kingdom-source income or a United Kingdom nexus.

What does this cover in practice? The diagnostic identifies:

The principal's current United Kingdom residence status under the Statutory Residence Test and the number of days available before a clean break.
Any United Kingdom-incorporated or United Kingdom-managed entities that may be treated as United Kingdom-resident on a management-and-control basis.
Trust structures with a United Kingdom-resident settlor, beneficiary or trustee – each of which can create an ongoing United Kingdom charge even after the principal's personal departure.
United Kingdom-situated assets (real property, United Kingdom-listed securities, intellectual property registered in the United Kingdom) that remain within the charge regardless of personal residence.
Outstanding tax filings, elections, and protective claims that need to be in place before departure.

This step is done before any entity is moved, any new Hong Kong structure is formed, or any announcement is made to counterparties. The diagnostic is the gate. Nothing proceeds until it is complete.

A common error at this stage is to treat the diagnostic as a formality that can run concurrently with the move. In practice, the outcome of the diagnostic alters the sequence of what follows. We have seen cases where a trust restructuring done before the diagnostic was complete created an additional United Kingdom charge that the post-move position could not unwind.

Cross-border note: if any entity in the structure is incorporated in the British Virgin Islands, the Cayman Islands, or another offshore centre and is currently managed and controlled from the United Kingdom, that entity's residence position under both the United Kingdom rules and the Hong Kong rules needs to be assessed explicitly. Under Hong Kong's territorial regime, an offshore entity deriving income from outside Hong Kong is generally outside the profits-tax charge – but that position depends on the facts, including where decisions are genuinely made.

Step 2 – United Kingdom exit: the Statutory Residence Test and the clean-break gate

Ceasing United Kingdom tax residence requires satisfying the departure conditions under the Statutory Residence Test. The test is day-count-based and tie-count-based: it is not enough to leave; the principal must leave on terms that, objectively assessed against the test's automatic overseas tests and sufficient-ties tests, produce a non-resident outcome from a defined date.

The gate at this step is the split-year rule. Under United Kingdom domestic law, a year of departure may be treated as a split year, meaning the principal is treated as resident for part of the year and non-resident for the remainder. The split-year treatment is not automatic – it requires one of the statutory cases to apply. Identifying which case applies, and ensuring the conditions for that case are met on the facts, is a technical exercise. United Kingdom-side counsel handles this step; our role on the Hong Kong side is to sequence the Hong Kong steps so that no action in Hong Kong prejudices the split-year position.

For a family-office principal with multiple ties to the United Kingdom – accommodation, family, employment or directorship – the Statutory Residence Test can produce an unexpected result. The day-count rules are unforgiving. A principal who spends more than the permitted days in the United Kingdom in the first post-departure year may remain United Kingdom-resident for that year regardless of Hong Kong substance.

Practical sequencing point: the day-count for the United Kingdom year begins the moment the departure date is set. The Hong Kong arrival date and any travel back to the United Kingdom during the first year must be planned against the test from day one. We work alongside United Kingdom-side advisers to model the day count before the move, not after.

A further charge to address at this step is the United Kingdom's temporary non-residence rules (which can bring certain gains and income back into charge if the principal returns to United Kingdom residence within a defined window). The implication for the Hong Kong structure is clear: the structure needs to be built for permanence, not for a five-year interlude.

Step 3 – Establishing Hong Kong residence: the management-and-control test and substance requirements

Establishing Hong Kong residence requires more than arriving and renting office space. For the family office itself – and for any corporate entities that are to be treated as Hong Kong-resident – the management-and-control test is the operative standard under the Inland Revenue Ordinance.

A company is resident in Hong Kong for tax purposes if its central management and control is exercised in Hong Kong. This is a functional test, not a registration test. A company incorporated in the BVI but managed and controlled from Hong Kong is a Hong Kong-resident entity for tax purposes. Conversely, a company incorporated in Hong Kong but managed and controlled from the United Kingdom remains a United Kingdom-resident entity for United Kingdom tax purposes under the equivalent test – and may have been so throughout the principal's United Kingdom period.

What does central management and control mean in practice? The courts have addressed this consistently: it means the high-level strategic decisions of the company – not day-to-day operational management. Board meetings held in Hong Kong, attended in person by directors who have genuine decision-making authority and who bring substantiated deliberation to the meeting, satisfy the test. Paper board meetings attended remotely by nominees who have not considered the material do not.

The substance requirements that accompany the foreign-sourced income exemption (FSIE) regime – which governs the treatment of certain foreign-sourced income (dividends, interest, disposal gains, and intellectual-property income) received by a Hong Kong-resident entity – reinforce the point. Under the FSIE regime, in force from 1 January 2023 as amended, qualifying income is exempt from profits tax only if the entity meets the economic-substance requirement or the participation exemption or nexus requirement as applicable. For a family-office holding entity, the economic-substance test requires adequate employees, adequate premises, and adequate expenditure in Hong Kong. These are not notional requirements.

The gate at this step is the substance file: a documented record of the decision-making process, the physical presence, and the operational expenditure in Hong Kong, assembled from the first day of operation. We regularly advise on how to structure the substance file so that it is audit-ready from the outset, not reconstructed after the fact.

Step 4 – Restructuring the holding layer: BVI, Cayman, and the move of management and control

A United Kingdom family office commonly holds assets through a BVI or Cayman holding entity, with a sub-layer of operating companies or investment vehicles. When the principal moves to Hong Kong, the question is whether those holding entities move with them or remain in their current jurisdictions under their current governance.

The answer turns on the management-and-control test applied in both the exiting jurisdiction (the United Kingdom, and the offshore centre under its own economic-substance rules) and the receiving jurisdiction (Hong Kong under the Inland Revenue Ordinance and the FSIE regime).

The sequencing requirement here is precise. The management-and-control function of a holding entity should not shift to Hong Kong until:

The principal is substantively present in Hong Kong – not still day-counting for the United Kingdom clean break.
The Hong Kong entity or office infrastructure is in place to receive the function.
The FSIE substance analysis for any entity expected to receive foreign-sourced income has been completed.
The offshore-centre economic-substance rules have been reviewed to confirm that removing management and control from that jurisdiction does not trigger a filing or substance breach.

Moving board meetings and signing authority to Hong Kong before the substance infrastructure is in place creates a gap: the entity is no longer managed and controlled in the offshore centre, but the Hong Kong substance test is not yet satisfied. In that gap, neither jurisdiction's beneficial position applies cleanly. We have seen this produce adverse assessments in both directions.

For BVI and Cayman entities, the economic-substance regimes in those jurisdictions apply to entities carrying on certain relevant activities. An entity that ceases to be managed from the BVI or the Cayman Islands may need to file a notification with the relevant registry. Parties should verify the current filing requirements before acting.

Inward re-domiciliation is a separate tool worth noting. Hong Kong introduced an inward company re-domiciliation regime in 2025, allowing an eligible non-Hong Kong company to re-domicile to Hong Kong while preserving its legal identity. Parties should verify the current commencement date, eligibility criteria, and perimeter of that regime before considering it as a structural option.

If an earlier structure or an incomplete management-and-control transfer has produced a stalled or adverse result, a second-read assessment can identify where the sequence broke and what routes remain open. Contact info@lockhartyip.com to discuss.

Step 5 – Trust and succession: re-governing or restating under Hong Kong law

Trust structures are frequently the most complex element of a United Kingdom family-office relocation. A trust established under English law, with a United Kingdom-based trustee or a United Kingdom-resident settlor, does not automatically become a Hong Kong-law trust when the principal moves. The governing law follows the instrument, not the location of the principal.

The Trustee Ordinance (Cap. 29), substantially reformed with effect from 1 December 2013, provides a well-developed statutory base for Hong Kong-law trusts. Key features relevant to the relocation context:

The rule against perpetuities and the rule against excessive accumulations were abolished for Hong Kong trusts by the 2013 reform, giving a family-office trust indefinite duration.
A settlor may reserve certain powers over the trust without the trust being invalidated on that ground under Hong Kong law – which is a materially different position from the United Kingdom's general-law approach.
Hong Kong law has no forced-heirship regime (a legal requirement in some jurisdictions to pass a minimum share of an estate to defined heirs). The 2013 reform also strengthened Hong Kong-law trust protection against foreign forced-heirship claims, relevant for principals with family members in civil-law jurisdictions.

The gate at this step is the governing-law and trustee analysis. If the trust deed contains a governing-law clause pointing to English law, changing that requires a formal amendment or a restatement with the consent of the relevant parties. If the trustee is a United Kingdom-incorporated professional trustee, the trustee appointment and the duties owed under the trust remain subject to United Kingdom regulatory oversight even after the principal's departure.

For a family office moving from the United Kingdom, the practical approach is to assess whether the trust structure is to be maintained under English law with a United Kingdom-regulated trustee, or whether it is to be re-governed under Hong Kong law with a Hong Kong-managed trustee, or whether a new Hong Kong-law structure is to be established alongside the existing trust for new assets. Each of these paths has different tax, succession, and administrative implications. The decision depends on the nature of the assets, the identity of the beneficiaries, and the family's long-term succession plan.

Our desk works on trust and succession planning across the Hong Kong–United Kingdom interface, including coordination with trustees and fiduciary advisers on the re-governing process. See also our related practice on capital relocation, which covers the broader structural and substance-filing requirements for principals moving to Hong Kong.

Step 6 – Banking and the source-of-funds file

Opening and operating a Hong Kong bank account for a newly relocated family office requires a well-documented source-of-funds file. Hong Kong banks operate under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance and the Hong Kong Monetary Authority's AML guidelines. For a principal whose wealth originated in the United Kingdom – through a business sale, investment portfolio, trust distribution, or inheritance – the file needs to trace the origin of funds through a documented chain that satisfies a compliance officer working under those rules.

United Kingdom-origin wealth is generally well-documented by institutional standards: company accounts, tax returns, solicitor's completion statements on a business sale. The challenge arises where the chain includes offshore-held assets, trust distributions where the trust's own records are incomplete, or historical transactions that predate modern record-keeping standards.

The gate at this step is document completeness before the first banking approach. A family-office principal who approaches a Hong Kong bank without a complete source-of-funds file will experience a protracted onboarding process or a refusal. Remediation after refusal is significantly harder than preparation before approach.

For principals whose prior holding was through a Singapore or Cyprus structure, we have written separately on source-of-funds file preparation for those specific corridors: see our guides on the Singapore-principal-to-Hong-Kong-bank source-of-funds file and the Cyprus-principal-to-Hong-Kong-bank source-of-funds file. The United Kingdom corridor has its own documentation norms, but the underlying structure of the file – origin, movement, current holding – follows the same logic.

Step 7 – The decision checklist and common mistakes to avoid

The most common mistake in a United Kingdom-to-Hong Kong family-office relocation is treating it as a single event rather than a sequenced process. A principal who incorporates a Hong Kong entity, rents office space, and then flies back to the United Kingdom to manage the transition for six months has not relocated. They have created a new structure while retaining the old residence position.

The second most common mistake is misaligning the management-and-control transfer with the personal residence timeline. An entity is managed and controlled where its directors actually make decisions. If the board minutes record Hong Kong as the decision-making location but the directors are still physically in London, the record does not match the reality. Inconsistency of this kind is the single most-examined point in a management-and-control challenge.

The third mistake is leaving trust governance unaddressed. A trust with a United Kingdom-resident trustee remains subject to United Kingdom regulatory and tax rules. Moving the principal without moving the trustee – or at least assessing the trustee position – leaves a United Kingdom tail that can take years to unwind.

Use this checklist before each stage of the move:

Pre-move diagnostic complete – United Kingdom residence position confirmed; all United Kingdom-source and United Kingdom-managed entities mapped; trust and fiduciary positions identified.
United Kingdom exit plan confirmed – split-year case identified; day-count modelled for the full first post-departure year; temporary non-residence window noted.
Hong Kong substance infrastructure in place – office, employees, and decision-making process operational before the management-and-control transfer.
FSIE analysis complete – for each entity expected to receive foreign-sourced income, the applicable exemption (economic substance, participation, or nexus) identified and substance file begun.
Holding-layer sequencing confirmed – BVI or Cayman economic-substance filing obligations reviewed; management-and-control transfer timed to follow, not precede, Hong Kong substance readiness.
Trust and succession structure assessed – governing-law clause reviewed; trustee position assessed; decision made on re-governing, restating, or running in parallel.
Source-of-funds file prepared – origin of wealth documented and ready for Hong Kong banking onboarding.
Ongoing compliance calendar set – profits tax returns, Significant Controllers Register obligations, FSIE filings, and offshore economic-substance filings diarised.

Is every box ticked before the first entity move? If not, the sequence is not yet ready.

Frequently asked questions

How long does the United Kingdom-to-Hong Kong family-office relocation usually take?

The full process – from pre-move diagnostic to a substantively operational Hong Kong family office with a complete banking relationship – typically takes between 12 and 24 months for a principal with an established trust structure and multiple holding entities. The United Kingdom exit conditions under the Statutory Residence Test set a minimum timeline for the personal tax-residence position, and the substance-building requirements in Hong Kong run concurrently. Parties should not plan for a relocation that completes faster than the residence test allows. The exact timeline depends on the complexity of the existing structure and the jurisdictions involved.

What is the first step in the United Kingdom-to-Hong Kong family-office relocation?

The first step is the pre-move diagnostic: a full mapping of the principal's United Kingdom residence position under the Statutory Residence Test, the management-and-control position of all entities in the structure, and the trust and fiduciary arrangements that carry a United Kingdom nexus. This step precedes any entity formation in Hong Kong, any transfer of management-and-control functions, and any public announcement. The diagnostic outcome determines the sequence of all subsequent steps and frequently reveals adjustments that must be made to the existing structure before the move begins.

Do I need a Hong Kong adviser for the United Kingdom-to-Hong Kong family-office relocation?

Yes. The relocation spans two legal systems, and the sequencing decisions that arise on the Hong Kong side – the management-and-control transfer, the FSIE substance analysis, the trust re-governing question, and the banking and source-of-funds file – require specific knowledge of Hong Kong law and practice. A United Kingdom adviser who does not have a Hong Kong cross-border practice will not cover these points. In our experience, the most common sequencing errors arise precisely because the Hong Kong-side analysis was deferred or delegated to United Kingdom counsel who were working beyond their jurisdiction.
