Update: treaty access between Hong Kong and the United Kingdom

For groups structured through Hong Kong with income flows toward the United Kingdom – or in the reverse direction – treaty access has become a sharper compliance question. Substance requirements on both sides of the corridor are tightening, and tax authorities in each jurisdiction are applying closer scrutiny to the documents a claimant entity must produce before relief is granted under any applicable arrangement.

Treaty access between Hong Kong and the United Kingdom turns on two parallel tests: whether the claiming entity meets the source and residence conditions under Hong Kong's territorial tax system, and whether it can satisfy the relevant anti-avoidance provisions applied by HM Revenue and Customs. Neither test is satisfied by incorporation alone. The governing instrument on the Hong Kong side is the Inland Revenue Ordinance, which defines the source and residence position; the United Kingdom applies its own domestic gateway rules alongside the arrangement itself.

This briefing sets out what practitioners on our desk are seeing across the corridor, who it affects, and the immediate steps that matter.

What Is Driving the Current Scrutiny

Hong Kong operates a territorial tax system. Profits are taxable in Hong Kong only where they arise in or derive from Hong Kong. That principle, which sits at the core of the Inland Revenue Ordinance, is also the starting point for treaty access: an entity that cannot demonstrate genuine Hong Kong-source or Hong Kong-resident status is poorly placed to claim relief under any arrangement with the United Kingdom.

The pressure point is substance. A holding or intermediate entity that collects dividends, royalties, or interest flowing between Mainland China or other Asian markets and a United Kingdom parent or subsidiary must demonstrate that its functions, personnel, and decision-making are genuinely located where it claims to be resident. In our cross-border practice, we regularly see structures where the legal seat and the commercial reality have drifted apart – a position that leaves the entity exposed on both sides.

On the United Kingdom side, HMRC applies anti-avoidance provisions that look through arrangements designed to obtain treaty benefits that would not otherwise be available. An entity interposed primarily for treaty shopping will not obtain the relief its principals expected. The consequence is double exposure: taxed in the source jurisdiction without relief, and potentially subject to further scrutiny in the recipient jurisdiction.

The foreign-sourced income exemption (FSIE) regime – Hong Kong's regime conditioning exemption of foreign-sourced passive income on economic-substance criteria, in force from 1 January 2023 as amended – adds a further layer. Dividend, interest, and royalty flows into a Hong Kong entity are tested against the FSIE conditions before the entity can claim exemption in Hong Kong. Failing the FSIE test can also undermine the treaty-access argument, since it calls the entity's genuine economic presence into question.

The sequence of steps is where the route is won or lost. The tax-residence and source position must be documented before a claim is lodged, not assembled after an inquiry opens.

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.

Who Is Affected and the Immediate Action

The practical impact falls on several distinct categories of group. Holding entities incorporated in Hong Kong or offshore but managed from Hong Kong, with income flows to or from the United Kingdom, sit at the centre of the issue. So do UK-headquartered groups that route Asian income through a Hong Kong intermediate. Family offices with assets split between Hong Kong and the United Kingdom – a corridor we see regularly – face the same substance documentation requirement.

What does the immediate action look like? Three steps are priority for any affected entity.

First, review the entity's tax-residence and source position under the Inland Revenue Ordinance. This is not a paper exercise. It requires an honest assessment of where decisions are made, where key personnel are located, and whether the entity's functions are consistent with the income it collects.

Second, map the relevant arrangement's conditions against the entity's documented position. The arrangement between Hong Kong and the United Kingdom imposes conditions that must be satisfied at the time a claim is made. A review now – before a return is filed or an inquiry opens – allows a group to identify and close gaps. Parties should verify the current conditions with qualified advisers before acting.

Third, assess the FSIE position in parallel. Where foreign-sourced passive income flows into a Hong Kong entity, the economic-substance conditions under the FSIE regime must be satisfied, and the documentation must be contemporaneous. A post-hoc assembly of records is a recognised risk point in HMRC-led reviews as well as IRD inquiries.

If an earlier structure or filing has produced an adverse or stalled result, a second read of the entity's position can identify the point of failure and the routes still open. In our cross-border practice, the most common error is treating treaty access as a legal conclusion rather than a factual position that must be built and maintained.
