Update: a tax-efficient holding route between the CIS and Hong Kong

For principals based in Commonwealth of Independent States (CIS, the post-Soviet economic grouping) jurisdictions structuring capital through Hong Kong, the critical question has never been the headline rate. Hong Kong's territorial profits tax – 8.25% on the first HK$2,000,000 of assessable profits, 16.5% above that – is well understood. What is not always settled, and what our desk sees as the recurring trigger for structural problems, is whether the offshore holding entity meets the substance and source requirements that determine whether Hong Kong's territorial exemption actually applies.

A tax-efficient holding route between the CIS and Hong Kong turns on source and substance under the Inland Revenue Ordinance and the foreign-sourced income exemption (FSIE) regime, not on rate shopping. Income routed through a Hong Kong holding company is only outside the profits-tax charge where it is genuinely foreign-sourced and, under the FSIE regime in force from 1 January 2023, where prescribed economic-substance conditions are satisfied.

This briefing identifies what changed, who it affects across the CIS–Hong Kong corridor, and the immediate structural steps that follow.

What has changed and why it matters now

Two developments compound each other for CIS-origin groups using Hong Kong as a holding hub.

First, the FSIE regime (the foreign-sourced income exemption, operative from 1 January 2023 as amended) brought dividends, interest, disposal gains and royalties into charge where the recipient entity does not meet prescribed economic-substance conditions in Hong Kong. The regime was designed to align Hong Kong's territorial system with international minimum-tax standards. For a passive holding company incorporated in Hong Kong that receives dividends from a CIS operating subsidiary, the substance question is now a live tax issue, not a compliance formality.

Second, the Pillar Two minimum top-up tax and the income inclusion rule apply to in-scope multinational enterprise groups for fiscal years beginning on or after 1 January 2025. Groups with consolidated revenue at or above EUR 750 million are within scope. For larger CIS-origin groups, the interaction between Hong Kong's territorial system, the FSIE substance conditions, and the Pillar Two top-up charge requires modelling before the structure is set.

The combined effect is that a Hong Kong holding vehicle that was tax-efficient under the pre-2023 position may now carry a materially different tax profile. Our cross-border practice sees this mismatch repeatedly on inbound CIS mandates.

Who is affected across the CIS–Hong Kong corridor

The affected class is broader than the Pillar Two threshold suggests. Even groups well below EUR 750 million in revenue face the FSIE substance conditions. A holding company that exists principally on paper – a registered address, a nominee director, and no genuine management or operational activity in Hong Kong – is precisely the structure the FSIE regime targets.

Practically, this covers: CIS commodity and manufacturing groups with a Hong Kong holding company above an operating subsidiary; family-office principals who incorporated a Hong Kong vehicle to hold a portfolio of CIS and offshore assets; and treasury or intermediate holding entities used to on-lend capital into the CIS from a Hong Kong base. In each case, the source and substance analysis must be redone against the current instruments.

For further background on the treaty-access dimension relevant to offshore structures connected to this corridor, our analysis of treaty access between Hong Kong and the Cayman Islands sets out a comparable set of substance and residence issues in a related context.

The sequence matters as much as the structure. A separate matter note on a tax-efficient holding route between Mainland China and Hong Kong illustrates how the source and substance analysis runs in practice across a parallel corridor.

What to do now

The immediate priority is a source-and-substance review of the existing Hong Kong holding vehicle against the FSIE regime and, where Pillar Two applies, a preliminary effective-tax-rate model. Three questions frame the review.

First, is income received by the Hong Kong entity genuinely foreign-sourced under the Inland Revenue Ordinance? The characterisation is fact-specific and turns on where decisions are made, where contracts are concluded, and where the economic activity generating the income is carried out.

Second, does the entity satisfy the economic-substance conditions prescribed under the FSIE regime for the category of income it receives? The conditions differ by income type; the bar for a pure equity-holding company is different from that for an entity earning royalties or interest.

Third, if the group is within Pillar Two scope, what is the effective tax rate in each constituent-entity jurisdiction, including Hong Kong? The interaction between a territorial exemption, an FSIE top-up charge, and a Pillar Two top-up charge can produce unexpected layering.

Our Tax Positions practice works through this analysis for CIS-origin groups at the point of initial structuring and on review of existing vehicles. The source and substance position should be settled before the holding route is committed, not after the first profits-tax return is filed.
