Update: a Mainland China holding company over a Hong Kong operating entity

A Mainland China holding company sitting above a Hong Kong operating entity creates a structurally inverted position that the standard outbound-holding playbook does not cover. The cross-border interface – where the Mainland corporate-law and foreign-investment regime meets Hong Kong's common-law operating environment – governs substance, treaty access and beneficial-ownership analysis in ways that a chart on paper rarely shows.

The trigger is not new. But our desk has seen it recur with renewed urgency in 2025 and into 2026: groups that established the inversion during an earlier phase of Mainland expansion are now meeting substance challenges, dividend-flow interruptions and beneficial-ownership questions from counterparties, banks and tax authorities on both sides.

What the Current Environment Is Producing

Two convergent pressures are driving the issue. First, the foreign-sourced income exemption (FSIE regime – Hong Kong's economic-substance conditions for passive income to qualify for exemption from profits tax) has been in force since 1 January 2023, as amended. A Hong Kong entity receiving dividends upward into a Mainland holding structure must satisfy FSIE conditions or face a Hong Kong profits-tax charge on income previously treated as exempt.

Second, the Mainland's own beneficial-ownership and anti-avoidance rules look downward as well as upward. Where a Hong Kong operating entity earns income from third parties and distributes it to a Mainland holding company, tax authorities on both sides scrutinise whether the structure holds genuine substance or functions as a conduit.

Treaty access – in this corridor, the Arrangement between the Mainland and Hong Kong for the Avoidance of Double Taxation – does not follow automatically from the corporate chart. It follows from substance, control and beneficial ownership, assessed at the time a distribution or payment is made. Groups that assumed the arrangement's reduced withholding rates applied to their structure, without reviewing the substance position, are the ones appearing in remediation files on our desk now.

The position under the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), which came into force on 29 January 2024, adds a further dimension. Where a contractual or corporate dispute arises between the Mainland holding entity and its Hong Kong subsidiary – or between either and a third party – the enforcement route across the boundary now operates under a regime that is materially wider than the one it replaced. Groups should understand which court's judgment will need recognition where before a dispute crystallises.

Who Is Affected

The structure affects three identifiable cohorts. The first is a Mainland-headquartered industrial or technology group that incorporated or acquired a Hong Kong operating entity and left it beneath the Mainland parent without reviewing the substance and treaty position after the FSIE amendments took effect.

The second is a founder-owned group that used a Mainland holding company for domestic regulatory reasons – foreign-investment approvals, onshore asset registration, sector restrictions – and now wishes to raise external capital, list offshore, or make a cross-border acquisition through the Hong Kong entity. The inversion becomes an obstacle at due-diligence stage.

The third cohort is the in-house or group treasury team managing dividend repatriation and intercompany loans across the two entities. Where the holding company is on the Mainland side, the direction of cash flow, the applicable withholding rates and the substance evidence required differ from the conventional outbound structure. Getting it wrong means a higher effective tax rate and a weakened position in any beneficial-ownership challenge.

Our desk sees all three. The common factor is that the structural decision was made – for entirely rational reasons at the time – without building in a periodic review trigger. The 2023 FSIE amendments and the 2024 enforcement ordinance are both now material facts that post-date many of these structures.

The Immediate Action

Three steps are worth taking now, before a transaction, a tax query or a counterparty challenge forces the issue.

First, map the actual substance position of the Hong Kong operating entity and the Mainland holding company against the FSIE conditions and the beneficial-ownership test in the double-taxation arrangement. This is a document-led exercise: board resolutions, management accounts, payroll records, and evidence of decision-making in the relevant jurisdiction. If the records do not support the claimed position, the time to address it is before a dividend distribution, not after.

Second, assess whether the inversion is still the right configuration for the group's next phase. An offshore holding layer – a BVI or Cayman entity above both – may resolve the substance and treaty questions more cleanly than retrofitting the Mainland holding company. Equally, a Hong Kong intermediate holding company introduced between the Mainland parent and the operating entity can re-establish the conventional structure. Neither option is right in every case; the answer turns on the group's ownership, sector and forward plans. See our Holding Structures practice and the guide on structuring ahead of a Mainland China listing or exit for the comparative analysis.

Third, review the dispute-resolution and enforcement provisions in the key contracts between the Mainland holding entity and the Hong Kong operating entity. Under Cap. 645, an effective Mainland judgment in a civil or commercial matter can now be registered in the Court of First Instance in Hong Kong. Groups that drafted their intercompany agreements before January 2024 may wish to align the forum and governing-law clauses with the current regime. For family-owned groups operating this corridor, the related structuring considerations are addressed in our analysis of holding structures for family-owned groups with Mainland exposure.

The sequence above describes the standard position. Your matter turns on the documents, the jurisdictions actually engaged, and the order of steps – which is where the route is won or lost. To discuss how the cross-border interface applies to your structure, contact info@lockhartyip.com.
