A practical guide to the United Kingdom-to-Hong Kong family-office relocation

Moving a family office from the United Kingdom to Hong Kong is not a simple change of address. It is a sequence of legal, structural and tax decisions that interact – and that must be completed in a specific order if the move is to produce the intended result. The window is not indefinite. Both the UK and Hong Kong tax authorities focus on the management-and-control test: the question of where a structure is actually run, not merely where it is registered. Getting the sequence wrong can produce a period in which the office is simultaneously taxable in two places.

A UK-to-Hong Kong family-office relocation requires the coordinated migration of tax residence, management-and-control, substance and trust or holding structures across two common-law jurisdictions. Hong Kong operates a territorial profits-tax system – taxing only Hong Kong-sourced profits, with no capital gains tax and no withholding tax on dividends – making it a structurally different environment from the UK. The Trustee Ordinance (Cap. 29) governs Hong Kong trusts; the Inland Revenue Ordinance governs the tax position. The move involves both.

This guide sets out the decision the principals face, the steps in sequence, the gates at each step, the common mistakes counsel on this desk regularly sees, and a checklist for in-house teams preparing the instruction file.

What decision does the family office actually face?

The starting point is always a choice between three structural positions, not one. The first is a full migration: the office ceases UK operations, the management moves, the corporate entities re-domicile or are replaced, and UK tax residence ends. The second is a dual presence: the UK entity remains, and a new Hong Kong platform is established alongside it. The third is a partial migration: the principals relocate but the UK structures stay, with a managing director or trustee appointed in Hong Kong to carry the management function.

Each model carries a different risk profile. The dual-presence model is the one most commonly attempted without advice and the one most frequently productive of difficulty. The UK's controlled foreign company rules and the management-and-control test can reach back into the Hong Kong structure if the principals retain effective direction from London – or if they return frequently enough to be treated as resident again.

The partial-migration model, done correctly, is a legitimate and often used structure for families where one generation remains UK-based. Done carelessly – with a nominee director in Hong Kong who takes no real decisions – it produces a structure that nominally sits in Hong Kong but remains taxable in the UK. Tax authorities on both sides have developed experience in identifying nominee arrangements. Our cross-border practice sees this pattern regularly among principals who have moved informally before engaging international counsel.

The answer to which model applies is fact-specific. The principal's domicile, the nature of the family assets (real property, private equity, listed securities, operating businesses), the trust structures already in place, and the residence history of other family members all bear on the choice. The guide that follows assumes a full or materially full migration, which is the most demanding – and the most legally consequential – of the three paths.

How does UK tax residence end – and when does it actually end?

UK tax residence ends under the UK's statutory residence test, which applies a day-count and tie-breaker analysis that looks at the prior three UK tax years. This is the gate before anything else can be properly planned. Until the principal's UK residence position is clear, the Hong Kong side cannot be built with confidence.

The key misconception our desk sees is that residence ends on the day the principal boards the flight. Under the statutory residence test, a person who was UK tax resident in all of the preceding three years and who has more than two UK ties – including a family tie, an accommodation tie, a work tie or a 90-day tie – may remain UK resident even if they spend fewer than 91 days in the UK in the relevant tax year. The tie analysis is therefore run first, before any departure date is fixed.

The second misconception concerns the split-year treatment. Where the statutory residence test recognises a split-year, income arising in the overseas part of the year may fall outside UK income tax. But the split-year is not automatic. It applies only where one of a defined set of cases is met, and it does not apply in the same way to capital gains, to income from UK-situated assets, or to UK real property gains. A principal with a UK residential property portfolio, for example, remains within the scope of UK non-resident capital gains tax regardless of where they live.

The practical gate at this stage: the UK residence-cessation date, the split-year position, and the treatment of any protected foreign pension provision must all be established before the family office's management function shifts to Hong Kong. This is counsel work, not an administrative filing. The Inland Revenue in the UK (His Majesty's Revenue and Customs) will ordinarily be notified, and the last UK self-assessment position should be settled before exit. Parties should verify the current filing requirements and deadlines with locally admitted UK tax counsel before acting.

How is management-and-control transferred to Hong Kong?

The management-and-control test is the common-law test used in both the UK and Hong Kong to determine where a company is resident for tax purposes. A company is resident where its central management and control is exercised – meaning where its board meets, takes decisions, and holds real authority, not merely where it is registered or where its directors nominally sit.

For a family-office holding company, this means the following steps must be completed in sequence. First, the board must be reconstituted so that a majority of directors are physically present in Hong Kong when board meetings are held. Second, the strategic and treasury decisions of the office – investment approvals, banking mandates, distribution authorities – must be actually taken in Hong Kong, by directors present in Hong Kong, and documented by minutes prepared and kept in Hong Kong. Third, the registered office and company secretarial function must be moved to Hong Kong, through locally licensed Hong Kong firms with whom we work. Fourth, the banking relationships must be established at Hong Kong-regulated institutions before the UK banking relationships are wound down.

The order matters. A structure that opens a Hong Kong bank account but continues to take investment decisions by email chain originating in London has moved the banking but not the management-and-control. That is not a migration. It is an additional administrative layer that may produce a dual-residence outcome without the benefits of either jurisdiction's tax position.

A practical marker: the first board meeting held physically in Hong Kong, at which substantive decisions are taken and documented, is the evidential starting point for the Hong Kong management-and-control position. The date of that meeting should be recorded and preserved. Everything before it – the appointment of directors, the opening of accounts, the establishment of office space – is preparation. The meeting is the beginning.

What about the family principals themselves? If the principals are also directors of the holding company, their physical presence in Hong Kong at board meetings is important for the management-and-control analysis. But the principals' personal tax residence and the company's tax residence are separate questions. Both must be addressed, and each has its own test and its own evidentiary requirements.

What is the correct sequence of steps?

The sequence for a full UK-to-Hong Kong family-office relocation runs as follows. Each step has a gate: the next step should not be taken until the preceding gate is cleared.

Step 1 – Establish the UK departure position. Run the statutory residence test analysis for the principals and for any corporate trustees resident in the UK. Identify the expected cessation date. Identify the UK tax liabilities that crystallise on departure or within the first non-resident year (particularly in relation to UK-situated assets and employment-related securities). Gate: a written position paper from UK-admitted tax counsel confirming the departure date and the residual UK filing and payment obligations.

Step 2 – Map the existing structure. Produce a complete structure chart showing every entity, every trust, every nominee holding and every bank account. Identify which entities are UK-resident, which are offshore, and which are arguably already dual-resident. Identify the governing law of every trust. Gate: a clear structural diagram confirmed by all advisers.

Step 3 – Establish the Hong Kong platform. Incorporate or re-domicile the holding entities for the Hong Kong operations. The Companies Ordinance (Cap. 622) governs Hong Kong-incorporated companies. A Hong Kong inward company re-domiciliation regime commenced in 2025 and may be available for eligible non-HK entities, allowing an existing entity to migrate its legal identity to Hong Kong while preserving continuity – parties should verify the current eligibility conditions and commencement details before relying on this route. Open banking relationships with Hong Kong-regulated institutions, working with locally licensed firms on the account-opening compliance file. Gate: entities incorporated or re-domiciled; banking operational; corporate secretarial in place.

Step 4 – Transfer management-and-control. Hold the first substantive board meeting in Hong Kong. Adopt new banking mandates and investment authorities in Hong Kong. Transfer the treasury function. Gate: board minutes, new mandates, and an updated company-secretarial file confirming Hong Kong management.

Step 5 – Review the trust structure. If there are existing UK trusts, assess whether the trustee's residence should be migrated to a Hong Kong or offshore trustee. The Trustee Ordinance (Cap. 29) – which was substantially reformed with effect from 1 December 2013 – governs Hong Kong trusts. It abolished the rule against perpetuities and excessive accumulations for Hong Kong trusts and strengthened protection against foreign forced-heirship claims. If the existing trust is UK-law governed, a change of governing law or a migration of trustees to a Hong Kong or offshore trustee may be considered, depending on the trust deed's terms. Gate: legal review of each trust deed; confirmation of trustee-migration authority; appointment documentation.

Step 6 – Establish Hong Kong tax substance and filings. Hong Kong's territorial profits-tax system means the office will pay profits tax only on Hong Kong-sourced profits. The two-tier rate is 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above. There is no capital gains tax and no withholding tax on dividends or interest in the general position. The foreign-sourced income exemption (FSIE) regime applies to passive income received by a company from outside Hong Kong – economic-substance conditions must be met if the income is not to be deemed Hong Kong-sourced. This is the step that requires the earliest engagement with a Hong Kong tax adviser, even though the filing obligation typically arises around 18 months after incorporation. Gate: FSIE analysis completed; economic-substance arrangements documented; tax adviser retained.

Step 7 – Wind down the UK operational footprint. Resign UK-resident directors where appropriate. Notify UK Companies House of changes. Settle the final UK tax position. Close or restructure UK bank accounts where the operation has moved. Gate: final UK tax returns filed or in preparation; UK Companies House record updated; no residual management function remaining in the UK.

What does the cross-border interface between Hong Kong and the United Kingdom look like in practice?

Hong Kong and the UK are both common-law jurisdictions. That shared legal tradition means that Hong Kong courts approach questions of trust construction, fiduciary duty and contractual interpretation in a manner familiar to UK-trained counsel. It does not mean the tax regimes are similar – they are structurally different – or that a structure designed for the UK market performs the same way in Hong Kong.

The single most important cross-border point for a family-office relocation is that the UK and Hong Kong do not have a comprehensive double-tax agreement. There is a limited arrangement covering certain categories of income – specifically, air transport and shipping – but there is no general income-tax treaty between the two jurisdictions. That absence means double-taxation relief in the transition period, if any, must be found in the domestic rules of each jurisdiction, not in a treaty mechanism. This is not fatal to the relocation, but it must be planned for. Income arising in the transition period – between the point the UK residence clock stops and the point the Hong Kong substance is fully established – requires particular attention.

The second cross-border point concerns enforcement. A judgment obtained in the UK courts is not automatically enforceable in Hong Kong. There is a common-law route by which a UK money judgment may be pursued in Hong Kong, treating the judgment as a debt and commencing fresh proceedings. This is not registration in the sense that the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645) – in force since 29 January 2024 – provides for Mainland judgments. The UK-HK enforcement route requires fresh action and is slower. For a family office with contractual counterparties or lending relationships that span the two jurisdictions, this is a structuring point, not merely an academic observation.

Third: the UK's trust-law position. A UK-law governed trust with UK-resident trustees may be subject to UK trust taxation even if the beneficiaries relocate. The interaction between UK trust tax, the UK's treatment of offshore trusts with UK-resident beneficiaries, and the Hong Kong position requires a cross-border analysis that neither jurisdiction's domestic adviser can give alone. Our role in this context is the coordinating counsel function – mapping the interaction and identifying the points where locally admitted UK advice is needed alongside the Hong Kong and offshore analysis.

What are the common mistakes – and how does careful sequencing avoid them?

Four mistakes account for most of the remediation work our desk sees in this practice area.

The first is moving the person before moving the structure. A principal who arrives in Hong Kong as an individual, but whose holding company remains UK-resident by management-and-control, has changed their personal tax residence but not the office's position. The office continues to pay UK corporation tax until the management-and-control is genuinely transferred. This is the most common error and the one most easily avoided by treating the company's migration and the individual's migration as two separate exercises, each with its own checklist and its own completion date.

The second is the nominee-director arrangement that does not hold. Appointing a Hong Kong-based director to sign documents without giving that director real authority is not a management-and-control migration. Tax authorities are experienced in looking behind nominee arrangements. The question asked is not "who signed the minutes?" but "who decided the matter that the minutes record?" A Hong Kong director who rubber-stamps decisions made by a London principal at a weekly call does not move the management-and-control. The London principal does.

The third mistake is neglecting the FSIE regime. A Hong Kong holding company that receives dividends, interest, royalties or disposal gains from offshore sources may be subject to Hong Kong profits tax on that income if it does not have adequate economic substance in Hong Kong. "Economic substance" is not a high bar for a genuine family office – it requires real management, real staff or service providers, and real records – but it is a bar. A holding shell with no staff, no office and no real activity fails the test. The FSIE regime has been in force since 1 January 2023. It is not a new risk, and it should be addressed at Step 6, not discovered during the first profits-tax inquiry.

The fourth mistake is treating the trust structure as a given. A UK trust with a UK-resident trustee does not automatically become a Hong Kong trust when the principals relocate. The trust's residence for tax purposes follows the trustee's residence. If the trustee remains UK-resident and the trust has UK-resident beneficiaries, the UK trust-tax analysis continues to apply. Where the family's intention is to operate as a genuinely Hong Kong-centred family office, the trust structure must be reviewed and, where necessary, the trustee position must be moved. That review is not optional: it is the foundation of the structure.

If an earlier filing, structure or enforcement attempt produced an adverse or stalled result, a second read can identify the strategic error and the routes still open. Email info@lockhartyip.com with a summary of the position.

A short checklist for in-house teams

The following questions form a working checklist for the in-house counsel or family-office adviser preparing the instruction file. A "no" or "uncertain" answer at any point indicates a gap that should be resolved before the next step is taken.

• Has the UK statutory residence test been run for each principal and each UK-resident corporate trustee?
• Has a written UK departure position been obtained from locally admitted UK tax counsel?
• Is the full structure – entities, trusts, nominees, bank accounts, governing laws – mapped and confirmed?
• Are the Hong Kong holding entities incorporated or re-domiciled, with locally licensed corporate secretarial in place?
• Has the first substantive board meeting been held physically in Hong Kong, with minutes preserved?
• Have new banking mandates and investment authorities been adopted in Hong Kong, at meetings of directors present in Hong Kong?
• Has the FSIE position been analysed and the economic-substance arrangements documented?
• Has the governing law and trustee-residence position of each trust been reviewed by counsel familiar with both the UK and Hong Kong regimes?
• Has the UK operational footprint been wound down: directors resigned, Companies House updated, residual UK filing obligations identified?
• Has the absence of a UK-Hong Kong income-tax treaty been factored into the transition-period income analysis?

This checklist is a starting point, not a complete review. The interaction of UK trust taxation, FSIE, the management-and-control test and the personal residence analysis of each principal produces a fact-specific result that varies with every family. The window in which a clean migration is available – before the principal's ties to the UK are analysed at the end of the relevant tax year – is defined by the calendar, not by the adviser's convenience.

Decision matrix: which route, which instrument, which timing

The situation and the applicable route depend on the principal's existing structure and the speed of the intended move.

A principal with a simple holding structure – one UK-resident company, no trust, one or two investment accounts – faces the most straightforward path. The company's management-and-control is transferred to Hong Kong by reconstituting the board and holding meetings there. The principal ceases UK residence under the statutory residence test. The FSIE and profits-tax position is established at incorporation or re-domiciliation. The risk is timing: if the company's management-and-control moves before the principal's UK residence ceases, or after it ceases but before the Hong Kong substance is adequate, a gap opens. The sequence at Steps 1 through 6 above is designed to close that gap.

A principal with a UK-law trust, multiple underlying entities, and UK real property faces a materially more complex path. The trust-migration step requires a legal review of the trust deed and – if the trust is to change its governing law or move its trustee – the consent of all relevant parties and possibly the sanction of a court. The UK real property remains within the scope of UK non-resident capital gains tax regardless of the migration. The interaction with the FSIE regime for income from the property, if any, must be assessed separately. The timeline for this structure is typically measured in quarters, not weeks.

A principal with existing offshore structures – a BVI or Cayman holding entity above the UK operating layer – may find that the offshore layer simplifies the migration. The offshore holding entity is not UK-resident by management-and-control if its board genuinely meets offshore; its migration to a Hong Kong-managed position may require only a change of directors and banking, not a change of jurisdiction of incorporation. Whether stamp duty considerations arise on any transfer of assets into or out of Hong Kong depends on the nature and location of the assets: the ad valorem stamp duty of 0.1% per party applies to transfers of Hong Kong stock, but shares of a non-HK company holding no HK-situated assets are generally outside Hong Kong stamp duty – parties should verify on the specific facts.

Where a principal is uncertain which model applies, the practical starting point is always Step 1 and Step 2 of the sequence: establish the departure position and map the structure. Everything else is built on those two foundations.
