Update: the Hong Kong source and territorial position for a foreign group

For foreign groups with Hong Kong operations, trading relationships, or holding entities, the question of where profit is sourced is not academic. It decides whether Hong Kong profits tax applies at all. The Inland Revenue Department's approach to the source question has long been the sharpest edge of Hong Kong's territorial system – and it remains the trigger point that foreign counsel most frequently misjudge.

Hong Kong taxes profits on a territorial basis: only profits arising in or derived from Hong Kong are chargeable under the Inland Revenue Ordinance. The rate is 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that threshold for corporations. But the rate is secondary. The threshold question – whether the profit is Hong Kong-sourced at all – determines the exposure. For a foreign group routing income, services, or capital through Hong Kong, that question turns on facts, not structure alone.

This briefing covers what is driving the current risk, who across the cross-border corridor is most exposed, and what to do now.

What the source question means in practice – and where the risk sits now

The Inland Revenue Ordinance does not define "source" by formula. The courts and the Inland Revenue Department apply an operations test: where are the profit-generating activities carried out? For a Hong Kong entity acting as a regional intermediary, procurement hub, or service platform for a foreign group, that question is live on every transaction.

The risk profile has sharpened for two reasons. First, the foreign-sourced income exemption (FSIE) regime – the set of rules requiring economic substance for offshore passive income claims – has been in force since 1 January 2023, as amended, and the Inland Revenue Department has been active in substance reviews. A foreign group that assumed Hong Kong entities would simply pass income offshore without substance is now exposed both on the FSIE conditions and on the underlying source analysis.

Second, the Pillar Two minimum top-up tax, effective for fiscal years beginning on or after 1 January 2025 for in-scope groups with consolidated revenue at or above EUR 750 million, adds a second layer of exposure. Where the effective tax rate in Hong Kong falls below the global minimum, a top-up charge may arise in another jurisdiction. The source position in Hong Kong therefore affects not only Hong Kong tax but the group's global Pillar Two position.

In our cross-border tax practice, we see foreign groups most exposed in three recurring patterns: a Hong Kong entity executing contracts for a non-Hong Kong parent without clear documentation of where the profit-generating activity sits; a holding entity receiving interest, royalties, or dividends and relying on an offshore claim without satisfying the FSIE substance conditions; and a regional management or treasury function that has grown in operational scope without a corresponding review of its Hong Kong source position.

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 territorial rules apply to your group's Hong Kong position, contact info@lockhartyip.com.

Who is affected across the corridor – and what to do now

The territorial system affects every foreign group with a Hong Kong presence, but the exposure is not uniform. Three categories of group should act now.

Groups using Hong Kong as a regional hub or intermediary. Where a Hong Kong entity performs services, procurement, or trading functions for the wider group, the source analysis needs to match the operational reality. If the documentation describes an offshore model but the activity is in Hong Kong, the Inland Revenue Department will look through the documentation to the facts.

Groups claiming offshore status for passive income under the FSIE regime. The regime requires that passive income – dividends, interest, royalties, and gains on disposal of equity interests – meets substance, nexus, or participation conditions to qualify for exemption. A claim that does not satisfy those conditions is taxable. Parties should verify the current position before acting.

In-scope MNE groups managing Pillar Two exposure. For groups at or above the EUR 750 million revenue threshold, the Hong Kong effective tax rate is an input into the global Pillar Two calculation. A position that reduces Hong Kong tax below the global minimum without satisfying a substance-based carve-out will generate a top-up charge elsewhere in the group.

The immediate action for each category is the same: map the profit-generating activities against the entities and jurisdictions, test the source position under the operations test, and confirm that any offshore or exemption claim is supported by substance. Where the Hong Kong entity interacts with a Mainland China counterpart, treaty access under the Comprehensive Double Taxation Arrangement between the Mainland and Hong Kong may also be relevant – see our matter note on treaty access between Hong Kong and Mainland China for the cross-border interface on that corridor.

For groups using offshore holding centres above their Hong Kong operations, the interaction between the territorial source position and the holding structure is a separate but connected question. Our matter note on tax-efficient holding routes between Cyprus and Hong Kong sets out how that interface operates in practice.

If an earlier filing or structure has produced an adverse or stalled result with the Inland Revenue Department, a second read can identify the strategic error and the routes still open. Email info@lockhartyip.com with the outline facts.
