Matter note: treaty access between Hong Kong and Mainland China

Treaty access between Hong Kong and Mainland China is one of the most commercially consequential tax questions for Asian groups using a Hong Kong holding layer. The Arrangement between the Mainland and Hong Kong for the Avoidance of Double Taxation (the HKSAR-Mainland DTA) reduces withholding tax on dividends, interest and royalties flowing upward from a Mainland operating entity to a Hong Kong holding company. The rates matter. But the route to those rates – the substance and source analysis that must precede any application – is where matters are won or lost.

Mainland tax authorities apply a beneficial-ownership test and a substance requirement before granting reduced treaty rates under the HKSAR-Mainland DTA. A Hong Kong holding company must demonstrate genuine economic presence and control, not merely a corporate address. Since the Pillar Two minimum-tax regime took effect for in-scope groups for fiscal years beginning on or after 1 January 2025, the substance calculus has become more precise and more auditable than at any earlier point.

This matter note describes an anonymised cross-border engagement our tax-positions desk handled. It follows the situation, the constraint, the route chosen, the sequence, the turning point, and the transferable lesson for groups with similar exposure.

What was the situation, and where did it begin?

A mid-market industrial group headquartered outside Greater China had operated through a Hong Kong holding company for several years. Below the holding company sat a wholly foreign-owned enterprise incorporated in the Mainland, the group's primary revenue-generating entity. Dividends had been flowing upward. The holding company had been claiming the reduced rate on outbound dividends available under the HKSAR-Mainland DTA.

The group's position had not been examined closely since initial setup. The holding company carried a Hong Kong registered office address, a corporate secretary, and a small number of directors – most of whom were resident outside Hong Kong. Board meetings had occurred irregularly and, in several cycles, entirely by written resolution from outside the territory.

The triggering event was a notification from the Mainland tax authority. The authority had selected the group's Mainland entity for review and was querying the basis on which the reduced withholding rate had been applied. The query was framed around beneficial ownership and the substance of the Hong Kong holding company. Correspondence had already been exchanged at the level of the Mainland entity's local tax adviser, with limited success. The group came to us at that point – after an initial filing, with the review open and a response deadline approaching.

The commercial stakes were concrete. The differential between the standard and reduced rates on a sustained dividend stream represented a significant sum. More acutely, the Mainland authority had indicated that it was considering whether prior-period applications had been correctly made. That raised the question of retrospective adjustment, which changed the risk profile considerably.

What was the cross-border issue at the centre of the matter?

The core issue was not the rate. It was beneficial ownership and substance under the territorial system. The HKSAR-Mainland DTA does not operate automatically. Access to reduced rates requires that the recipient entity in Hong Kong satisfy the beneficial-ownership condition: the Hong Kong holding company must itself be the genuine beneficial owner of the dividend, not a conduit for an entity elsewhere.

Mainland tax guidance on beneficial ownership has been developed through a series of administrative circulars. Those circulars identify a set of unfavourable indicators – among them, entities with little or no independent decision-making capacity over the receipt and use of income, entities where substantially all income is passed through to a third-country parent within a short period, and entities whose directors or managers have no real connection to Hong Kong. The group's holding company, as constituted, exhibited several of these indicators.

The secondary issue was management and control. Under Hong Kong's territorial tax system, a company incorporated in Hong Kong is not automatically resident there for treaty purposes. Residence, for purposes of the DTA, follows the place of central management and control. Where directors are habitually outside Hong Kong, and board deliberations occur outside the territory, the risk of a finding that the holding company is not resident in Hong Kong – and therefore not within the DTA at all – becomes real.

These two issues – beneficial ownership and effective management – are distinct, but they interact. In our cross-border practice, we regularly see groups that have treated them as the same question. They are not. A company can be managed and controlled in Hong Kong yet still fail the beneficial-ownership test if it lacks the capacity to deploy the income it receives. The reverse is also possible: a company with genuine discretion over its assets but whose directors meet abroad, and who therefore has a residence problem distinct from ownership.

The third layer was timing. The review was live. The group needed to respond with a defensible position, based on existing documents and facts, while simultaneously rebuilding the substance position for future periods. Those two tasks require different approaches. The response to the review must be grounded in what exists; the remediation work is prospective. Conflating them – which foreign-based advisers sometimes do – risks producing a response to the authority that overstates the current substance position and exposes the group to further scrutiny.

What route did the matter take, and where was the turning point?

Our first step was a document review. We examined the holding company's constitutional documents, its board minutes and resolutions over the relevant review period, the dividend declarations and resolutions, the director-residence positions, and the existing correspondence with the Mainland authority. We mapped each of the unfavourable indicators identified in the applicable administrative guidance against the factual record. That produced a clear picture: several indicators were present; a small number were arguable; and one – the question of how income was used after receipt at the Hong Kong level – was, on the documents available, potentially defensible.

The turning point came during the document review. A set of resolutions from an earlier period showed that the Hong Kong holding company had, on two occasions, retained dividend income within Hong Kong for a material period before any onward distribution was decided. During those periods, the board – including a Hong Kong-resident director whose appointment had not been widely publicised internally – had separately approved a short-term treasury deployment. Those two documented episodes were the factual anchor for a beneficial-ownership argument. They showed genuine discretion. They were not decisive on their own. But they were real and they were documented.

We structured the response to the Mainland authority around those episodes, coupled with a management-and-control memorandum that addressed the residence question directly rather than leaving it implicit. The memorandum acknowledged that certain board meetings had occurred outside Hong Kong but demonstrated, by reference to the resident director's contemporaneous conduct, that key decisions relating to the Hong Kong holding company's income were made within the territory.

In parallel, we prepared a prospective substance plan for the holding company. This involved identifying the minimum threshold of genuine activity required to maintain a credible position, the board composition changes needed to bring effective management consistently into Hong Kong, and a revised dividend-approval process designed to produce a clear record for future periods. We coordinated the prospective plan with locally licensed Hong Kong firms who advised on the corporate-governance and directorship aspects. The two workstreams – the response to the review and the remediation – were kept formally separate in our advice and in the documents produced, to avoid any suggestion that the remediation acknowledged a deficiency in the prior position.

The Mainland authority's review was resolved without a retrospective adjustment being imposed. The current-period position was accepted on the basis of the factual materials provided. The prior-period query was closed by demonstrating the documented instances of genuine discretion. We do not attribute this outcome to any single factor. The combination of a factually grounded response, a clear management-and-control analysis, and the documented evidence of discretion produced a defensible file.

What is the transferable lesson for similar structures?

The lesson is not about rates. Groups focusing on the headline differential between the standard withholding rate and the reduced treaty rate often invest heavily in the application and too little in the factual record that supports it. The HKSAR-Mainland DTA's beneficial-ownership condition is a facts-and-circumstances test. It does not yield to legal argument alone. It requires a documented history of genuine decision-making at the Hong Kong level.

What does that mean in practice? It means that the board of the Hong Kong holding company must meet in Hong Kong, or at minimum that the Hong Kong-resident members of the board must be shown to have exercised genuine influence over income-related decisions. It means that dividend income received from the Mainland should not be automatically and immediately upstreamed. There should be a genuine deliberation – recorded in minutes – about whether, when and how to distribute. It means that treasury management, however modest, should be documented as a decision made in Hong Kong.

The interaction with the territorial tax system matters here. Under Hong Kong's territorial basis, the holding company's own profits-tax position is determined by whether the income arises in or derives from Hong Kong. For a holding company receiving dividends – which are not taxable as such under the territorial system – this is not the primary concern. But the foreign-sourced income exemption (FSIE) regime, in force since 1 January 2023, imposes economic-substance conditions on certain categories of passive income that a Hong Kong entity receives from outside Hong Kong. Groups that have not reviewed their holding structure against the FSIE conditions since that reform may have an unaddressed compliance gap sitting alongside their treaty-access position.

The second lesson concerns the interaction between management-and-control and beneficial ownership. Groups that have addressed one but not the other carry residual risk. A review of the holding company's treaty-access position should cover both tests, with separate factual analyses for each. They draw on similar facts but ask different questions.

The third lesson is about timing. The most common pattern we see is a group that has applied the reduced rate for several periods before any review is initiated. By the time the authority queries the position, the factual record is what it is. The ability to build a response depends entirely on what documents exist. Groups that wait for a review before assessing their substance position have fewer options than those that maintain the record proactively. The window between the initial setup of a structure and the first Mainland tax-authority contact is the period in which a defensible position is built – or not.

For groups considering whether their Hong Kong holding layer is adequately positioned, the right question is not "have we been challenged?" It is "if we were challenged tomorrow, what is in the file?" That question has a concrete answer. And that answer can be improved.

If an earlier structure or treaty-access application produced an adverse or stalled result with the Mainland authority, a second read of the documentary record can identify the strategic gap and the routes still available.

What the review process looks like

Groups approaching us with a treaty-access question typically come with one of three starting points. The first is a prospective review: no review has been initiated, but the group wants to assess the strength of its current position and remedy any gaps before one is. The second is a live review: the Mainland authority has opened a query and a response is required. The third is a retrospective adjustment: an assessment has already been made and the group is considering its options.

Each starting point requires a different sequencing of work. For a prospective review, the document audit comes first, followed by a gap analysis against the beneficial-ownership indicators, then a substance plan. For a live review, the response to the authority takes priority, with the substance plan running in parallel as a separate workstream. For a retrospective adjustment, the available remedies depend on the jurisdictional rules governing objection and appeal timelines – which parties should verify with locally licensed advisers in the relevant jurisdiction.

In every case, the Hong Kong corporate-governance work – director appointments, board-meeting protocols, minute-keeping – is handled together with locally licensed Hong Kong firms. Our role is the international and cross-border analysis: the treaty interpretation, the substance analysis, the management-and-control memorandum, and the coordination of the response strategy across the Hong Kong and Mainland dimensions.

Our tax-positions desk operates at the intersection of tax structuring and cross-border advisory. On matters with a distribution or exit component that also carries a foreign-tax dimension, we often work alongside the analysis set out in our note on tax review before UAE exit or distribution. For groups managing ongoing residence and control questions at the holding-company level, our briefing on tax residence, management and control for holding companies covers the analytical framework in more detail.
