Where substance and management-and-control

The holding company registered in Hong Kong but directed from elsewhere is a familiar structure across Greater China and the principal offshore corridors. For years, the gap between the address on the register and the reality of where decisions were made carried manageable consequences. That gap is narrowing.

Substance and management-and-control (the test used to determine where a company is actually resident for tax and treaty purposes) are now the decisive factors in whether a Hong Kong holdco delivers the treaty access, the tax efficiency and the enforcement position its principals expect. The governing instruments are the Inland Revenue Ordinance, the foreign-sourced income exemption (FSIE) regime effective from 1 January 2023, and the OECD Pillar Two framework now operative for in-scope groups for fiscal years beginning on or after 1 January 2025. Getting substance wrong does not merely cost a treaty benefit. It can recharacterise the holdco's residence, expose passive income to the FSIE clawback, and – in the most acute cases – give an adverse tax authority in a second jurisdiction a viable argument that the entity was never resident in Hong Kong at all.

This analysis sets out what is actually at stake, how the cross-border interface between Hong Kong and the principal counterpart systems operates in practice, where the risk concentrates, and where our desk sees the exposure sitting for groups that have not refreshed their substance review since the 2023 and 2025 legislative shifts.

What is commercially at stake when a holdco's substance fails?

The commercial stakes are not primarily about reputation or compliance cost. They are about whether the structure does what it was built to do.

A Hong Kong holdco is typically placed above operating entities for three reasons: access to Hong Kong's network of tax treaties and comprehensive double-taxation arrangements (CDTAs, the bilateral instruments that reduce withholding on dividends, interest and royalties flowing upward), a common-law governance and enforcement environment, and the territorial tax system that leaves offshore and non-Hong Kong-sourced profits outside the charge. Strip out the substance that supports each of those, and you have a structure that costs money to maintain, carries director and compliance obligations, and delivers none of the commercial value that justified it.

The first casualty is treaty access. A holdco that cannot demonstrate genuine residence and management-and-control in Hong Kong is at risk of a challenge under the principal purpose test (the BEPS minimum standard requiring that a treaty benefit not be granted if one of the principal purposes of an arrangement was to obtain that benefit). That challenge does not come from the Hong Kong Inland Revenue Department alone. It comes from the source-state tax authority – a Mainland Chinese tax authority asserting that dividends flowing from a wholly-foreign-owned enterprise (WFOE, a foreign-invested enterprise incorporated under Mainland law) to the Hong Kong holdco do not qualify for the reduced 5% withholding rate available under the Mainland–Hong Kong CDTA to a Hong Kong resident holding at least 25% of the distributing entity. The commercial cost of that single failure, on a large inter-company dividend, is immediate and quantifiable.

The second is the FSIE position. Since the foreign-sourced income exemption regime came into force on 1 January 2023, interest, dividends, disposal gains and royalties received by a Hong Kong entity from an offshore source are, by default, treated as taxable in Hong Kong unless the entity meets economic-substance requirements. The assumption that offshore income simply passes through a Hong Kong holding entity without touching the profits tax charge is no longer available. Groups that built their structures before 2023 and have not revisited them are operating on a superseded analysis.

What does management-and-control actually mean, and how does the Inland Revenue Ordinance apply?

Management-and-control is where a company's central management is exercised – the test is factual, not formal, and the Inland Revenue Ordinance applies it to determine the residence of a company for Hong Kong tax purposes.

The test is not met by the location of incorporation, nor by the address of the registered office, nor by the identity of the nominee directors. It is met by the location where the board of directors actually makes substantive decisions on the policy and direction of the company. "Substantive" is doing a great deal of work in that sentence. Rubber-stamping decisions made in Singapore, Shanghai, or Geneva at a Hong Kong board meeting does not establish management-and-control in Hong Kong. A board that meets in Hong Kong and genuinely deliberates, challenges management proposals, receives and reviews financial information, and approves material transactions does.

In our cross-border practice, the pattern we see most often is a group where the senior principal or the group treasury function sits in one jurisdiction – frequently the UAE, the UK, or Mainland China – and the Hong Kong holdco directors are local service providers who sign whatever is placed before them. That arrangement may have been workable when Hong Kong treaty claims were rarely challenged. It is substantially more exposed now. The Mainland's tax authority, the State Taxation Administration (the agency responsible for Mainland China's tax collection and treaty administration), has published guidance on what it expects to see when a non-Mainland entity claims a reduced withholding rate. The guidance explicitly references management-and-control, the location of senior executives, and the decision-making record.

What the instrument says and what the audit examines are not always the same question. Counsel on our desk regularly see the disjunction between the governance documentation – board minutes, resolutions, service agreements – and the correspondence record, travel logs, and email trails that tell the actual story of where decisions were made.

How does the cross-border interface between Hong Kong and the Mainland actually bite?

The Mainland–Hong Kong cross-border interface is where management-and-control failures produce their sharpest immediate consequences, and the mechanism is the beneficial-ownership test applied to treaty claims.

The standard holding structure for a Mainland operating business involves a BVI or Cayman entity holding the Hong Kong holdco, which in turn holds the WFOE or the equity interest in a Mainland joint-venture partner. The Hong Kong entity is the treaty-access vehicle. For the CDTA reduced withholding rate on dividends to apply, the Hong Kong entity must be both a Hong Kong resident and the beneficial owner of the dividend – a concept that the Mainland's treaty administration has refined substantially through administrative guidance to require genuine economic substance, decision-making authority over the receipt of income, and a real business in Hong Kong.

Where those conditions are not met, the Mainland authority has the tools to disallow the treaty benefit and to apply the standard withholding rate instead, with penalties and interest if the position was taken on a self-assessed basis. This is not a theoretical exposure. In our experience advising groups with Mainland operating assets, the question of whether the Hong Kong holdco is genuinely resident and genuinely the beneficial owner of the inter-company income stream is the single most frequently audited aspect of outbound Mainland investment structures.

The enforcement dynamic has an additional layer since the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance took effect on 29 January 2024. That instrument, which operates at the level of civil and commercial judgment recognition, is not a tax instrument. But the existence of a closer mutual recognition relationship between Hong Kong and Mainland courts changes the risk calculus for groups that face a Mainland audit finding: the capacity to move assets or dispute findings between jurisdictions is more constrained than it was before that regime came into force.

Where does the FSIE regime place the burden now, and how does Pillar Two interact?

The FSIE regime places the burden of demonstrating economic substance squarely on the entity receiving passive income from an offshore source, and Pillar Two has sharpened the exposure for larger groups.

Under the FSIE regime, a Hong Kong entity that receives dividends, interest, disposal gains or royalties from outside Hong Kong is required to demonstrate that it meets the economic-substance test (for most income types) or the participation exemption (for dividends and disposal gains from a qualifying equity interest) before the income is exempt from profits tax. Economic substance, in this context, requires that the entity carry out qualifying activities in Hong Kong and that it have adequate employees and premises to conduct those activities. The activities must be performed in Hong Kong, not simply managed from Hong Kong by a director who spends most of the year elsewhere.

Pillar Two adds a second constraint for in-scope groups. The OECD's global minimum tax rules, now operative for in-scope multinational enterprise groups with consolidated revenue of at least EUR 750 million for fiscal years beginning on or after 1 January 2025, operate through a top-up mechanism that can impose additional tax at the level of a parent entity where a constituent entity in Hong Kong pays an effective rate below the 15% floor. A Hong Kong holdco that claims treaty benefits and FSIE exemptions without the substance to support them may be exposed to a top-up charge at the level of the ultimate parent, depending on that parent's jurisdiction. The interaction between the FSIE exemption conditions, the Pillar Two substance-based income exclusion, and the management-and-control test produces a three-variable analysis that groups built before 2023 have generally not conducted.

What does the comparative read across jurisdictions tell us?

The Hong Kong position on substance is not an outlier. It sits within a global convergence that has made the common pattern of using a thin holding entity for treaty access progressively harder to sustain. But the specific features of the Hong Kong system produce a risk profile that differs from the Cayman or BVI economic-substance regimes, and those differences matter in practice.

Consider the comparison with Singapore. Both jurisdictions operate territorial tax systems and both have extensive treaty networks. Singapore's Inland Revenue Authority has published guidance on what it requires to issue a certificate of residence – the document a Singapore resident entity uses to invoke a treaty benefit. The requirements include that the entity's control and management be exercised in Singapore. Hong Kong's Inland Revenue Department issues its own certificate of residence, and the criteria for issue overlap substantially with the management-and-control test under the Inland Revenue Ordinance. An entity that cannot meet those criteria in Hong Kong and is simultaneously considering a migration to Singapore will find that the same fundamental question – where are decisions actually made – applies with equal force in both jurisdictions.

The BVI and Cayman economic-substance regimes address a different question: whether a relevant entity in those jurisdictions meets the substance requirements for the specific category of business it conducts there. Those regimes were introduced in response to the EU and OECD pressure on pure holding-entity jurisdictions and apply mandatory substance requirements to income-producing activities. A BVI or Cayman entity that sits above a Hong Kong holdco does not thereby transfer its substance obligations to Hong Kong. The group must demonstrate substance at each level where a tax or treaty position is asserted. In our cross-border practice, we regularly see groups where the BVI or Cayman entity has satisfied its local substance requirements but the Hong Kong holdco – the entity actually invoking the treaty benefit – has not.

The UK comparison is also instructive. A United Kingdom holding company positioned above a Hong Kong operating entity faces its own management-and-control analysis under UK tax rules, with the risk that the entity is either resident in the UK (if managed and controlled there) or resident nowhere (if the claim to UK residence fails). Groups using a UK–Hong Kong bilateral structure should read both directions of the substance analysis. Our analysis of how that bilateral works is set out in the context of a United Kingdom holding company positioned above a Hong Kong operating entity.

What are the most common mistakes foreign principals and their advisers make?

The most pervasive mistake is treating management-and-control as a governance documentation exercise rather than a factual reality question.

Groups retain experienced corporate-services providers in Hong Kong, instruct them to hold regular board meetings, and generate a set of minutes that record deliberation and resolution. The problem is not the minutes. The problem is what happens between meetings: the group treasury function in Dubai approving a loan drawn on the Hong Kong holdco by email; the principal in London deciding to acquire an operating company and instructing the Hong Kong directors accordingly; the Hong Kong directors approving a dividend distribution based on a recommendation from the group finance team in Shanghai, on the same day the recommendation arrives. Each of those events – individually unremarkable, collectively critical – undermines the substance of the Hong Kong management-and-control claim. A well-kept set of board minutes cannot cure a correspondence record that tells a different story.

The second mistake is the FSIE assumption. Many groups with structures built before January 2023 are still operating on the pre-FSIE analysis that offshore income received by a Hong Kong entity simply does not enter the Hong Kong profits tax base because it is foreign-sourced. That position was broadly correct before the FSIE reforms. It is no longer the starting point. The starting point now is that such income is within the charge unless the entity meets the exemption conditions. Groups that have not conducted a post-2023 substance review for each category of income the Hong Kong holdco receives are carrying an unmodelled tax exposure.

The third mistake – less common but more damaging – is assuming that because the structure has not been challenged, it is defensible. Mainland audits of treaty positions tend to surface at the point of a significant transaction: a dividend repatriation, a disposal, a restructuring. By that point, the window for remediation is short and the options are constrained. We have acted on matters where a group arriving at completion of a significant disposal discovered that its Hong Kong holdco's treaty position was unsupportable and the withholding exposure had been unpriced in the transaction. Addressing the substance question before the transaction is materially more efficient than addressing it after.

If a previous structure review has produced an adverse finding, or if a current transaction has exposed a substance gap, a second read can identify the routes still open and the sequencing required. Write to info@lockhartyip.com.

What is our analytical read on where the risk sits now?

Our read, based on the pattern of matters we see in cross-border practice, is that the risk is no longer theoretical and has migrated from the realm of academic tax planning to the reality of operational audit and transactional due diligence.

Three conditions have converged to make this the current moment of sharpest exposure. First, the FSIE regime changed the legal starting point for offshore income. Second, the Mainland's treaty administration guidance has become more specific and more consistently applied. Third, Pillar Two has created a second enforcement vector for large groups that previously relied on the management of effective rates through treaty and exemption claims. Those three changes do not operate sequentially. They operate simultaneously on the same holdco.

The groups most exposed are, in our experience, mid-market and family-owned groups with Mainland operating assets and a Hong Kong holdco that has not been substance-reviewed since before 2023; groups that have a principal or group treasury function located outside Hong Kong and directors in Hong Kong who do not have genuine authority or operational involvement; and groups approaching a significant transaction – a disposal, a restructuring, a repatriation – where the treaty position will face scrutiny from a buyer's tax adviser, a Mainland tax authority, or both.

The groups least exposed are those that have genuinely located decision-making authority in Hong Kong, have conducted a post-2023 FSIE analysis for each income category, have adequate employees and premises for the activities being conducted, and can produce a coherent contemporaneous record – correspondence, resolutions, travel logs, banking records – that is consistent with the board minutes and the treaty claim. That standard is achievable. It requires deliberate construction, not passive assumption.

A decision matrix helps illustrate where the exposure concentrates:

For a group with Mainland operating assets, a Hong Kong holdco with nominee directors, and no post-2023 FSIE review: the instruments in play are the Inland Revenue Ordinance, the FSIE regime, and the Mainland–Hong Kong CDTA; the risk is a disallowed treaty claim on dividends and an FSIE charge on passive income received; the timing of exposure is the next significant dividend repatriation or the next Mainland audit cycle; and the remediation route is a substance review, a governance restructuring, and a prospective FSIE analysis, conducted before the transaction rather than during it.

For a large group within Pillar Two scope, with a Hong Kong holdco relying on the FSIE participation exemption: the instruments are the Inland Revenue Ordinance, the minimum top-up tax, and the global IIR mechanism; the risk is a top-up charge at the parent level if the Hong Kong effective rate falls below the 15% floor after the exemption is applied; the timing of exposure is the first in-scope fiscal year; and the remediation route is a jurisdictional effective rate analysis, a substance-based income exclusion calculation, and an adjustment to the group's income allocation model.

For a family-owned group using a Hong Kong holdco to hold UAE and Mainland assets, with the principal residing in the UAE: the instruments are the Hong Kong–UAE treaty arrangements, the Inland Revenue Ordinance, and the FSIE regime; the risk is that management-and-control is found to be in the UAE, the Hong Kong treaty position fails, and the FSIE exemption is unavailable; the remediation route is a genuine relocation of decision-making authority to Hong Kong, supported by a contemporaneous record. Our analysis of holding structures for family-owned groups with UAE connections is developed further in our guide for family-owned groups with UAE exposure.

How should a group approach the substance review in practice?

A substance review for a Hong Kong holdco is a factual investigation before it is a legal analysis. The starting point is the record, not the structure chart.

The review should produce a clear picture of where decisions on five categories of activity are actually made: the approval of material transactions; the management of treasury and banking relationships; the approval of inter-company income flows (dividends, loans, royalties); the appointment and supervision of senior management in operating entities; and the approval of group-level policies on tax, finance and compliance. For each category, the review maps the decision-makers, their location at the time decisions are made, the means by which the decision is recorded, and the consistency between the formal record and the informal trail.

The output of that investigation determines what remediation is needed. Where genuine substance exists but the documentation is inadequate, the remediation is primarily a record-keeping and governance exercise. Where genuine substance does not exist – because the real decisions are being made outside Hong Kong by principals or group executives who have not relocated – the remediation requires a structural decision: whether to genuinely relocate authority to Hong Kong, to restructure the holding layer to a jurisdiction where the substance genuinely exists, or to accept the tax and treaty consequences and price them into the group's planning. That is a commercial decision, not a legal one. What counsel can do is map the options and the consequences of each.

The FSIE analysis runs in parallel. For each category of offshore income received by the holdco – dividends from the Mainland WFOE, interest on inter-company loans, royalties from operating entities using group IP – the review should identify which exemption pathway applies (economic substance or participation exemption) and whether the conditions for that pathway are currently met. Where they are not met, the review should identify the gap and the path to closing it.

The management-and-control review and the FSIE analysis are not the same exercise, but they share evidence. A board that meets in Hong Kong, has genuine authority, employs or retains adequately qualified persons to conduct group holding activities, and maintains a contemporaneous record will generally be in a better position on both tests. The correlation is not coincidental. Both tests are asking, in different ways, the same underlying question: is there a real business here, or is this an address?

Our full analysis of holding structures and the options available through Hong Kong and the principal offshore centres is set out in our holding structures practice.

What the current environment means for groups that have not acted

The standard of substance required to support a Hong Kong holdco's treaty and tax position has risen materially since the FSIE reforms came into force and since Pillar Two became operative for large groups. Groups that built their structures before those reforms and have not revisited them are operating with a substance analysis that is no longer current.

The consequence is not simply the risk of a future audit finding. The more immediate consequence, for groups approaching a transaction, is that the buyer's tax advisers or the Mainland authority will conduct the substance analysis that the group has not conducted for itself. At that point, the findings become a negotiating tool, an escrow item, or a condition to closing. A gap identified in due diligence is a gap that a counterparty prices.

The corrective steps are available. The FSIE exemption conditions can be met prospectively. Management-and-control can be genuinely relocated to Hong Kong. The governance record can be reconstructed on a prospective basis, even where the historical record is thin. None of those steps are instantaneous, and none of them are retrospective – they change the position going forward, not the position as it stood in prior years. But for a group that still has time before a material transaction or a foreseeable audit, the cost of acting now is substantially lower than the cost of acting after the gap has been surfaced.

Frequently asked questions

What documents are needed for substance and management-and-control for a Hong Kong holdco?

Demonstrating substance and management-and-control in Hong Kong requires contemporaneous documentation that reflects where decisions are genuinely made. The core record includes board minutes evidencing deliberation in Hong Kong, a correspondence record consistent with those minutes, evidence of board members' physical presence at meetings (travel records, calendar entries), banking and treasury records operated from Hong Kong, and, for FSIE purposes, evidence of qualified employees or retained persons conducting the relevant holding activities in Hong Kong. The document set is evidence of reality, not a substitute for it. Where the underlying reality does not support the claim, no set of documents will cure the position. Parties should verify the current requirements before acting.

Do I need a Hong Kong adviser for substance and management-and-control for a Hong Kong holdco?

The substance and management-and-control analysis for a Hong Kong holdco engages both Hong Kong law (through the Inland Revenue Ordinance and the FSIE regime) and the law or treaty practice of the counterpart jurisdiction – typically the Mainland, the UAE, or a European home jurisdiction. A cross-border adviser with experience across both sides of the relevant interface is necessary to identify where the exposure sits, because the risk often arises at the junction between Hong Kong's rules and those of the source state. Locally licensed Hong Kong counsel are required for the Hong Kong law dimension. For the cross-border analysis, international counsel working alongside locally licensed firms is the standard coordination model.

What is the first step in substance and management-and-control for a Hong Kong holdco?

The first step is a factual investigation into where decisions on material matters are actually made, not where they are formally recorded. That investigation maps the five core decision categories – material transactions, treasury, inter-company income flows, supervision of operating management, and group policy – against the location and identity of the persons who actually make those decisions. The output determines whether genuine substance exists and, if so, whether it is adequately documented. If substance does not exist, the investigation identifies whether it can be constructed prospectively and at what cost. That factual mapping exercise is the necessary precondition to any legal analysis, any FSIE review, and any treaty claim assessment.
