Treaty access between Hong Kong and the CIS

A Hong Kong holding entity sits at the top of a group with operating subsidiaries across the CIS states. Dividends flow up. Royalties move across borders. The question that lands on the desk of a general counsel or group tax director is deceptively simple: does the Hong Kong entity actually qualify for treaty protection in the relevant CIS jurisdiction, or is it a conduit that will be challenged on audit? The answer turns not on the headline rate in the treaty text but on whether the structure can demonstrate substance, source, and beneficial ownership in a form that will satisfy a Mainland-trained or post-Soviet revenue authority conducting a real economic presence enquiry.

Treaty access between Hong Kong and the CIS states requires a Hong Kong resident entity to satisfy both the residency test under the applicable double taxation agreement and the beneficial ownership standard applied by the CIS counterpart authority – two conditions governed by distinct bodies of law that must be satisfied simultaneously, under the Inland Revenue Ordinance on the Hong Kong side and the relevant CIS domestic tax code on the other.

This page sets out how Lockhart & Yip structures the analysis and runs the engagement, where locally licensed counsel join the process, and what the client must own at each stage.

When does treaty access between Hong Kong and the CIS become urgent?

The trigger is almost always a concrete event rather than a planning exercise. A CIS revenue authority issues a questionnaire challenging the residency of the Hong Kong payee. A bank in Kazakhstan, Uzbekistan, or Russia requires a certificate of residence and a beneficial ownership declaration before processing a cross-border payment. A group is restructuring and the incoming acquirer's counsel have flagged that the existing treaty position has never been formally documented.

In each case the window closes faster than the client expects. A CIS withholding tax assessment, once raised, carries interest and penalties that accrue regardless of the underlying merits. An undocumented beneficial ownership position is extremely difficult to reconstruct after the fact because the contemporaneous board minutes, management accounts, and substance evidence that would have been straightforward to produce at the time of the relevant payment no longer exist in usable form.

Our desk sees this pattern regularly: a group that has relied on the treaty for several years without incident suddenly faces a focused challenge at the point of a refinancing, a sale, or a dividend repatriation of meaningful size. The commercial pressure at that moment is acute. That is why the analysis and the documentation need to precede the transaction, not follow it.

The other trigger that brings treaty access questions to a head is the tightening of economic-substance requirements. The foreign-sourced income exemption (FSIE) regime, which applies to passive income received in Hong Kong by entities that do not meet the substance threshold, took effect from 1 January 2023 and has been amended since. A Hong Kong holding entity that cannot demonstrate genuine management and control risks failing on two fronts simultaneously: no FSIE exemption in Hong Kong, and no treaty protection in the CIS state from which the income originates.

What is the governing framework on each side of the border?

On the Hong Kong side, the double taxation agreements concluded by Hong Kong are given effect through the Inland Revenue Ordinance. Hong Kong has a comprehensive network of such agreements, and a number of CIS states are counterparties. The treaty text typically follows the OECD Model Convention in its modern form, with a residency article and a beneficial ownership condition attached to reduced rates on dividends, interest, and royalties.

A Hong Kong entity is a Hong Kong resident for treaty purposes if it is incorporated in Hong Kong or, if incorporated elsewhere, managed and controlled in Hong Kong. Management and control in Hong Kong means real commercial decision-making by directors or officers physically present and acting in Hong Kong – not the registered office address, not the presence of nominee directors, and not the location of the bank account.

The Inland Revenue Department issues certificates of residence on application. These certificates are necessary but not sufficient: they confirm Hong Kong tax residency but do not predetermine beneficial ownership in the CIS state. That second question is resolved by the revenue authority in the counterpart jurisdiction applying its own domestic tax law and its own administrative practice.

On the CIS side, the legal environment is not uniform. Russia, Kazakhstan, Uzbekistan, Belarus, Azerbaijan, and the other CIS member states have each developed their domestic anti-avoidance regimes – including look-through rules, beneficial ownership provisions, and principal purpose tests – at different speeds and with different emphasis. Some states have implemented the OECD's base erosion and profit shifting recommendations directly into their tax codes. Others have developed parallel domestic doctrines that achieve similar results but use different concepts. Counsel advising only from the Hong Kong side cannot fully map this terrain; effective treaty access work requires coordinated input from counsel admitted in the relevant CIS jurisdiction.

That coordination is the core of what we provide. We structure and lead the Hong Kong analysis and substance review, and we work alongside allied counsel admitted in the relevant CIS state on the local beneficial ownership and anti-avoidance position. The client receives a single integrated view.

How does Hong Kong's territorial tax system affect the treaty access position?

This is the question that foreign principals most consistently underestimate – and the one that most often determines the outcome of a CIS audit challenge.

Hong Kong taxes profits on a territorial basis: only profits arising in or derived from Hong Kong are chargeable to profits tax. The two-tier rate is 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that threshold. There is no withholding tax on dividends or interest paid by Hong Kong entities to non-residents, and no capital gains tax. These features make Hong Kong genuinely attractive as a holding location. But they also mean that a Hong Kong entity receiving passive income from a CIS subsidiary may face an entirely separate question under the FSIE regime if the income is not sourced in Hong Kong and the entity cannot demonstrate the requisite substance.

Substance under the FSIE regime is not simply a matter of having an office and employees in Hong Kong. The nature of the income determines the nature of the substance required. For dividends, the test focuses on the management of the holding of the investment. For royalties, it focuses on research and development activities or the management of intellectual property. For interest, it focuses on the management of the debt asset. A CIS revenue authority asking about beneficial ownership will look at precisely the same factual questions – where decisions about the income are made, by whom, and based on what capacity – because those questions are the substance of the beneficial ownership enquiry under modern treaty practice.

The practical consequence is that the substance file built for FSIE purposes and the documentation prepared for a CIS beneficial ownership challenge are largely the same file. Groups that have done the FSIE work properly are in a substantially better position when a CIS audit begins. Groups that have not done it are exposed on both fronts simultaneously. That dual exposure is the risk we address in the engagement.

What is the cross-border interface between Hong Kong and the CIS in practice?

The interface operates on three planes simultaneously, and the sequencing across all three determines whether the treaty position holds under challenge.

First, the legal plane: the treaty text concluded between Hong Kong and the relevant CIS state defines the rate and the conditions. That text must be read alongside the OECD Commentaries, the CIS state's domestic anti-avoidance rules, and the Multilateral Instrument (MLI, the OECD Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting) as it applies to that bilateral treaty. Whether the MLI has modified the treaty – and which MLI options each party has adopted – is a question that varies by state and must be verified on the current position.

Second, the administrative plane: obtaining a certificate of residence from the Inland Revenue Department on the Hong Kong side, and navigating the beneficial ownership application or the withholding tax refund procedure on the CIS side, require different documents, different timelines, and different procedural steps. The certificate issued in Hong Kong must arrive in a form that the CIS counterpart authority recognises and accepts. Translation, apostille or legalisation requirements, and the submission format all differ by state and, in some states, by region.

Third, the substance plane: the board minutes, the meeting records, the management accounts, the director attendance evidence, and the service agreements that demonstrate real management and control in Hong Kong must all exist and be retrievable before the relevant income flows. Creating them after a challenge has been raised is significantly harder and carries its own credibility risk.

In our cross-border practice, we see the strongest treaty positions arise where the three planes are addressed as a coordinated programme rather than as separate tasks delegated to different advisers in different jurisdictions who do not speak to each other. The CIS revenue authorities are sophisticated enough to identify the seams between those advisers' work.

What is the step-by-step route we run with a client?

The engagement begins with a diagnostic. We review the existing structure: the Hong Kong entity's constitutional documents, its board composition, its management and control evidence, its income flows, and any prior treaty claims or correspondence from a CIS revenue authority. That review takes two to four weeks depending on the volume of documentation and the number of CIS jurisdictions engaged.

The diagnostic produces a gap analysis in three columns: what the Hong Kong side already supports, what is missing or insufficiently documented, and what needs to be addressed on the CIS side through allied counsel. The client sees this as a single memorandum. From that point, the client makes the commercial decisions – which gaps to close, in what sequence, and at what cost – and we execute the legal and documentary steps.

On the Hong Kong side, the steps typically include a management and control review, updated board procedures and minute-keeping protocols, an application to the Inland Revenue Department for a certificate of residence, and a substance assessment under the FSIE regime. Where the holding entity's function is thin, we model alternative holding arrangements and advise on the restructuring options – working with allied counsel admitted in the relevant offshore jurisdiction where a BVI or Cayman intermediate is involved.

On the CIS side, allied counsel admitted in the relevant state review the domestic beneficial ownership requirements, advise on the withholding tax application or refund procedure, and prepare the local documentation package. We coordinate the timing so that the Hong Kong certificate arrives in a form and within a window that the CIS procedure requires.

For a group with subsidiaries in multiple CIS states, the engagement runs as a parallel workstream by jurisdiction, with a single coordinating memorandum from our desk. The client's general counsel or group tax director receives one integrated update rather than separate reports from each jurisdiction.

Where a CIS assessment has already been raised, the route is different. We read the assessment, identify the factual and legal basis of the challenge, and advise on the defence position. Contemporaneous evidence that was not produced at the time of the payment is not lost, but it must be organised and presented credibly. We have acted on matters of this kind in the post-assessment phase and can assess what the position is and what options remain.

The sequence above describes the standard route. Your matter turns on the specific jurisdictions engaged, the existing documentation, and the stage at which the challenge has been raised – which is where the outcome is determined. If an earlier treaty claim or an insufficiently documented beneficial ownership position is now under scrutiny, we can assess the state of play and identify the routes still open.

What documents and decisions must the client own?

Treaty access work succeeds or fails on the quality of the client's own documentation. Advisers can structure the analysis and prepare the external submissions, but the contemporaneous evidence of substance is generated inside the client's own organisation. No adviser can manufacture that evidence retrospectively, and a CIS revenue authority that examines the board minutes for the relevant years will quickly identify minutes that were written after the fact.

The documents that the client must own fall into three categories.

The first is governance evidence: board minutes from the Hong Kong entity's meetings, signed by directors present in Hong Kong, covering the decisions that relate to the relevant income stream. These must exist for each period in which treaty protection is claimed. The minutes must record real decisions, not ratifications of decisions taken elsewhere. If the group has a parent entity in Europe or a principal in a CIS state that makes the commercial decisions, the minutes must show that those decisions were made by the Hong Kong board, even if they reflect the direction provided by the parent.

The second is financial evidence: management accounts for the Hong Kong entity, showing that the entity has the economic assets and rights consistent with its beneficial ownership claim. An entity that receives dividends from a CIS subsidiary but immediately passes them to a parent without any economic rationale for retaining value in Hong Kong will face a conduit challenge. The financial evidence must support the claim that the Hong Kong entity genuinely enjoys the income.

The third is operational evidence: service agreements, staffing records, lease or office evidence, and any other documentation showing that the Hong Kong entity has the physical and human capacity to perform the functions it claims. This evidence is specific to the income type: the requirements for a holding entity receiving dividends differ from those for a licensing entity receiving royalties.

The decisions the client must own are equally important. Whether to restructure the holding to strengthen substance, whether to apply prospectively for a certificate of residence or to defend an existing claim retroactively, and whether to negotiate with the CIS revenue authority or to litigate – these are commercial and strategic decisions that belong to the client. We provide the legal analysis and the options; the client makes the call.

What are the common errors that foreign principals make on this issue?

The most common error is conflating Hong Kong incorporation with Hong Kong residency for treaty purposes. A company incorporated in Hong Kong under the Companies Ordinance (Cap. 622) is a Hong Kong company. It is not automatically a Hong Kong tax resident for treaty purposes if its management and control is exercised elsewhere. A group that incorporates a holding entity in Hong Kong but has all the commercial decisions made by directors in Moscow, Almaty, or Dubai is not entitled to treaty protection simply because the registered office is in Central.

The second error is treating the certificate of residence from the Inland Revenue Department as a complete answer. The certificate confirms Hong Kong residency. It does not address beneficial ownership, and it does not bind the CIS counterpart authority. In our experience, groups that present a certificate of residence without the supporting substance file are challenged almost immediately on beneficial ownership grounds by the more active CIS revenue authorities.

The third error is failing to account for the Multilateral Instrument. Where the MLI has modified the bilateral treaty – introducing a principal purpose test or a simplified limitation on benefits clause – the pre-MLI analysis is no longer sufficient. Whether the MLI applies to a particular bilateral treaty, and which provisions have been adopted by both parties, must be verified on the current position for each CIS state in scope.

The fourth error is running the Hong Kong analysis and the CIS analysis in parallel but without coordination. The documents produced on the Hong Kong side must be consistent with the position advanced on the CIS side. An inconsistency between the two – for example, characterising the Hong Kong entity as a passive holding company for FSIE purposes while asserting active management functions for CIS beneficial ownership purposes – is a contradiction that a coordinated revenue examination will exploit.

Decision matrix: matching the situation to the route

The appropriate route depends on the client's situation at the moment of engagement.

Where no challenge has been raised and the group is structuring or documenting a new income stream: the route is prospective substance and documentation work. We build the governance and operational evidence file, prepare the FSIE substance assessment, and assist with the certificate of residence application in Hong Kong. Allied counsel in the relevant CIS state prepare the local documentation and advise on the applicable withholding procedure. The timeline is typically eight to twelve weeks from diagnostic to completion, depending on the number of jurisdictions and the complexity of the income flows.

Where the structure is established but has never been formally documented: the route is a retrospective gap-close. We review what evidence exists, identify what can be recovered or reconstructed with integrity, and advise on the risk profile of the undocumented periods. Where the risk is material, we advise on proactive disclosure options. This route carries more uncertainty than the prospective route but is substantially better than waiting for a formal challenge.

Where a CIS assessment or questionnaire has been issued: the route is a defensive analysis. We read the challenge, assess its legal basis, identify the available defences and the missing evidence, and advise on whether to respond directly, to negotiate, or to reserve the position. Allied counsel in the relevant CIS jurisdiction manage the local procedure. The timeline on this route is governed by the procedural deadlines in the CIS state, which are often short.

If a prior engagement with this issue – whether an internal review, an earlier adviser's opinion, or a previous treaty claim – has produced an unclear or adverse result, we can conduct a second review and identify what remains open.

If you are approaching a dividend repatriation, a refinancing, or a group restructuring that will bring the treaty position into focus, the time to address it is before the transaction, not after. Write to us at info@lockhartyip.com.

Practical example: a mid-market CIS industrial group

In autumn 2026, a mid-market industrial group with operating subsidiaries in three CIS states and a Hong Kong holding entity came to us ahead of a significant dividend repatriation. The group had used the Hong Kong holding structure for several years. It had a certificate of residence from the Inland Revenue Department but had not prepared a beneficial ownership file and had not addressed the FSIE regime. Two of the three CIS states in scope were in the process of updating their domestic beneficial ownership provisions.

We ran a diagnostic across all three CIS jurisdictions simultaneously. The diagnostic identified that the Hong Kong entity's board composition was adequate – directors were based in Hong Kong and held genuine decision-making authority – but that the minute-keeping had been inconsistent and one key dividend decision had been recorded only in the parent's group minutes, not in the Hong Kong entity's own records. The FSIE substance position for the dividend income was borderline given the volume of management services provided from outside Hong Kong.

We recommended a three-month remediation programme: updated board procedures, new minute-keeping protocols, and a revised FSIE substance assessment. Allied counsel in each of the three CIS states prepared jurisdiction-specific beneficial ownership memoranda and advised on the local withholding tax procedure. The dividend repatriation proceeded after the remediation was complete. The treaty position was not challenged in any of the three jurisdictions.

This type of matter – multiple CIS jurisdictions, an established but underdocumented structure, and a defined commercial transaction creating the window – is precisely the pattern we are built to handle.

Where do locally licensed Hong Kong firms join the process?

Lockhart & Yip advises on international and foreign law. We do not practise the law of Hong Kong. On the local law elements of a treaty access engagement – which arise in specific procedural steps – we work alongside locally licensed Hong Kong firms who handle those steps.

The points where locally licensed counsel are engaged include the application to the Inland Revenue Department for a certificate of residence, any formal correspondence with the Department on substance and residency questions, and any steps under the Companies Ordinance that form part of a governance remediation – for example, updating the register of directors or revising the articles of association to reflect changes in board procedures.

Our role is to structure the international analysis, coordinate across jurisdictions, and ensure that the Hong Kong legal steps and the CIS-side steps are sequenced and consistent. The client's point of contact is our desk throughout the engagement. The locally licensed firm works within the framework we have designed, not independently of it.

The coordination model means that the client does not need to manage a multi-party instruction directly. We carry the project management function. This is particularly important on multi-CIS engagements where the timing of the Hong Kong certificate, the CIS local documentation, and the transaction timeline must all align.
