A practical guide to the Hong Kong source and territorial position for a foreign group

A foreign group earning income from, or through, Hong Kong faces a deceptively simple question: which profits are taxable in Hong Kong, and which are not? The answer sits at the intersection of source doctrine, substance requirements, and the foreign-sourced income exemption regime – three mechanics that are easy to state and difficult to calibrate correctly without a structured review.

Hong Kong taxes profits on a territorial basis: only profits arising in or derived from Hong Kong are assessable under the Inland Revenue Ordinance. Profits that arise offshore are excluded, but that exclusion is conditional – it depends on where the operations that generate the profit actually take place, not on where the company is incorporated or where payments are routed. Since 1 January 2023, foreign-sourced passive income received by large multinational groups is also subject to the foreign-sourced income exemption (FSIE) regime, which imposes economic-substance conditions that change the calculus for holding and treasury entities.

This guide sets out the sequence a foreign group should follow, the gate at each step, the common mistakes we see, and a short checklist for the decision. It does not address every edge case; it gives you the right order of questions.

Why the territorial system is not as simple as the headline rate

Hong Kong's territorial system is frequently misread as a blanket exemption for offshore income. It is not. The system is a source test: the Inland Revenue Department assesses where the profit-generating operations are carried out, and that determination is fact-specific. The headline profits tax rate – 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that – only matters once you have settled the source question. Until then, you do not know the base.

In our cross-border practice, we see foreign groups make the same initial error: they assume that because a Hong Kong company contracts with non-Hong Kong counterparties, the profits are offshore. That assumption has never been reliable, and the IRD's long-standing approach under the operation-and-activity test makes it more precarious than ever. What matters is where the income-generating activities – negotiation, execution, decision-making, risk acceptance – actually occur. If those activities happen in Hong Kong, the profit is Hong Kong-sourced, regardless of where the counterparty or the goods sit.

The distinction between source (where the operations are) and residence (where the company is incorporated) is the conceptual gate every foreign group must pass through first. Hong Kong has no comprehensive tax-residence concept in the way that OECD systems do. A Hong Kong-incorporated company is not automatically taxable on its worldwide income; a non-Hong Kong company with operations in Hong Kong may nonetheless be assessable. Getting this right before a structure is committed is the single most important step in the sequence.

Step 1: map where your income-generating activities actually occur

The first operational question is a factual audit of where value is created, not where contracts are signed or payments are booked. The Inland Revenue Ordinance does not define "arising in or derived from Hong Kong" by reference to the place of contracting. Courts and the IRD have consistently applied a test that looks at the substance of the activities behind the profit.

For a trading entity, the relevant question is where the purchase and sale contracts are negotiated and concluded. If both legs of a buy-and-sell transaction are negotiated and concluded in Hong Kong, the profit is Hong Kong-sourced in full. If only one leg touches Hong Kong, an apportionment analysis may apply. For a services entity, the question is where the services are performed. For a financing entity, the question is where funds are deployed and managed. Each income stream in a group may have a different answer, and they must be assessed individually.

This audit is not a paper exercise. It requires a candid account of where the people making the commercial decisions sit, who negotiates the terms, and where the risk-acceptance decisions are made. Groups that have structured their operations to concentrate booking in Hong Kong while keeping decision-making offshore will find the source analysis runs against them – the reverse is equally true, and equally important for a group that wants to establish a genuine offshore position.

The output of Step 1 is a provisional source map: income streams categorised as Hong Kong-sourced, offshore-sourced, or mixed. That map drives every downstream step. For a broader view of the tax-positions practice and its interaction with treaty access, see our Tax Positions service page.

Step 2: apply the FSIE regime to passive income received by the Hong Kong entity

Once the source map is drawn, the next gate is the FSIE regime. Since 1 January 2023, specified categories of foreign-sourced income received in Hong Kong by a multinational enterprise group are subject to tax unless the entity meets the relevant economic-substance or participation conditions. The affected categories are dividends, interest, gains on disposal of equity interests, and income from intellectual property.

The FSIE regime targets passive income at the holding and treasury layer of a group – precisely the layer that most foreign groups route through Hong Kong. The logic is that if Hong Kong is to remain off the EU and OECD watch lists, it must impose substance conditions on passive income that would otherwise escape taxation entirely. The regime does not affect trading profits or active service income, which remain subject to the ordinary source test at Step 1.

The substance conditions vary by income type. For dividends and equity gains, a participation requirement or an economic-substance requirement applies. For intellectual property income, a modified-nexus approach applies, tracking the R&D expenditure that generated the IP. For interest, economic substance in Hong Kong is required. A group that cannot satisfy the relevant condition on receipt will face Hong Kong profits tax on the income despite its foreign source.

The practical implication for a foreign group is that the FSIE regime cannot be treated as an afterthought. A holding entity that receives dividends upstreamed from an Asian subsidiary, or a treasury entity that books interest from intra-group loans, must be assessed against the substance conditions before the structure is finalised. Where substance is thin or absent, the group faces either a tax charge or a restructuring cost. Identifying that gap at Step 2, before commitments are made, is materially cheaper than discovering it during an IRD enquiry.

Step 3: assess the Pillar Two position for MNE groups above the revenue threshold

For multinational enterprise groups with consolidated group revenue of EUR 750 million or more, an additional layer applies from fiscal years beginning on or after 1 January 2025: Hong Kong's minimum top-up tax and income inclusion rule, implementing the OECD Pillar Two global minimum tax. The minimum effective rate is 15%, applied entity by entity across the group's Hong Kong operations.

The Pillar Two charge does not replace the ordinary profits tax analysis at Steps 1 and 2. It sits on top of it as a floor. A Hong Kong entity that successfully demonstrates an offshore source for most of its profits, and thus pays a low effective rate, may nonetheless face a top-up charge if the group's overall effective rate in Hong Kong falls below the minimum. The interaction between the territorial source position and the Pillar Two effective-rate calculation is one of the more complex areas in our cross-border tax practice at the moment.

Groups below the EUR 750 million revenue threshold are outside the Pillar Two regime, at least in its current form. However, treaty-partner jurisdictions operating their own qualified domestic minimum top-up tax may reach the same entities through the underpaid-tax rule. The Pillar Two position therefore cannot be assessed by reference to Hong Kong in isolation; it requires a group-wide view of the effective rates in each material jurisdiction.

How does the cross-border element affect the source and territorial position?

The source analysis changes character when a foreign group operates across the Mainland–Hong Kong boundary. A group with procurement or principal operations in Mainland China and a Hong Kong entity acting as the offshore contracting vehicle faces a layered question: how much of the margin attributable to the Hong Kong entity is genuinely Hong Kong-sourced, and how much reflects value created on the Mainland? Where Mainland staff, premises, or infrastructure are used to generate the profit booked in Hong Kong, the source analysis will look through the structure to the operational reality.

This is where the cross-border element creates its most acute regulatory exposure. If the Mainland activities are not priced at arm's length through a transfer-pricing arrangement, the IRD may take the view that a greater portion of the profit is Hong Kong-sourced than the group has declared – or, conversely, the State Taxation Administration may take the view that profits have been shifted offshore. Both directions carry audit risk. In our cross-border practice, we regularly advise on the sequencing of the Hong Kong source analysis and the Mainland transfer-pricing position together, because they are two views of the same fact pattern.

The same tension arises in the context of treaty access (the right to claim reduced withholding tax rates under a bilateral tax arrangement). Hong Kong's network of comprehensive double-taxation arrangements is extensive, but treaty benefits are available only if the Hong Kong entity is a tax resident in Hong Kong within the meaning of the relevant arrangement. Under most of Hong Kong's arrangements, a company incorporated in Hong Kong will be treated as a Hong Kong resident unless the arrangement provides otherwise. The substance and management-and-control facts nonetheless matter for the competent-authority position and for the Mainland's beneficial ownership analysis on inbound dividends. Our separate analysis on treaty access between Hong Kong and Mainland China addresses those mechanics in detail.

The contextual bridge here is important. The source question in Hong Kong, the Mainland transfer-pricing question, and the treaty-access question are not three separate analyses. They are three angles on the same commercial and operational reality. A group that resolves one without the others risks an inconsistent position across the two systems.

If your group has an existing structure that was designed before the FSIE regime or before Pillar Two took effect, the source and territorial position should be reviewed against the current rules as a priority matter. To discuss where the gaps may lie, write to us at info@lockhartyip.com.

Step 4: identify the common mistake and how the sequence avoids it

The most common mistake we see from foreign groups approaching the Hong Kong source position is inverting the sequence: they begin with the tax rate and work backwards, rather than beginning with the source analysis and working forwards. The result is a structure optimised for the headline rate but exposed on the source question – a combination that produces the worst outcome, because the group has committed to operational and contractual arrangements that are difficult to unwind once the IRD forms a view.

A close second is the assumption that a Hong Kong entity which earns income from non-Hong Kong counterparties automatically earns offshore income. As noted at Step 1, that assumption has never been correct under Hong Kong's approach. But it has become more consequential since the FSIE regime added a second layer of substance inquiry for passive income. A group that assumed it was outside Hong Kong tax on dividends received from a BVI or Cayman subsidiary must now also satisfy the FSIE substance conditions – and in many cases, those conditions require a level of Hong Kong infrastructure that the entity does not have.

A third mistake, less common but more damaging, is treating the source question as settled once a tax opinion is obtained. The source analysis is fact-dependent, and facts change. If the operational footprint of the Hong Kong entity changes – because decision-makers relocate, because a new contract is executed, because a new service is added – the source position should be reviewed. An opinion obtained when the group's Hong Kong operations looked one way may not cover the current position.

The sequence in this guide avoids those mistakes by forcing the factual audit before any structural or filing decision. Source first. FSIE second. Pillar Two third. Cross-border interface throughout. The guide on the profits tax position for a Hong Kong trading entity works through the source mechanics for a trading entity specifically, and should be read alongside this guide where the group's primary Hong Kong activity is buying and selling goods or services.

If an earlier filing position or structuring opinion appears inconsistent with the current operational facts, a second review can identify the exposure and the corrective steps still available. Write to info@lockhartyip.com to discuss.

Step 5: document and maintain the position on an ongoing basis

A source position is not a one-time determination. It requires contemporaneous documentation of the facts that support it, maintained on an ongoing basis and updated when those facts change. The Inland Revenue Department can enquire into profits tax returns within defined statutory periods, and the enquiry will focus on the operational reality at the relevant time – not on the structure as it was designed, or on an opinion given before operations commenced.

The documentation standard that the IRD expects is fact-specific, but it generally includes records of where negotiations took place, who conducted them, where contracts were signed or approved, where risk decisions were made, and where the relevant personnel were located. For a FSIE position, additional documentation of economic substance is required: the number and qualifications of employees in Hong Kong, the level of operating expenditure, and the decision-making activity of the Hong Kong entity's board.

For a Pillar Two position, the documentation requirements are those imposed by the OECD Pillar Two model rules as implemented in Hong Kong. These include the GloBE information return (the Pillar Two group-level filing) and entity-level records supporting the effective-rate calculation. Groups should verify the current filing deadlines and requirements with their advisers before the first relevant fiscal year closes.

Maintaining the position also means monitoring for changes in law. The FSIE regime has already been amended since its introduction in 2023. The Pillar Two rules are subject to administrative guidance from the OECD that is still being issued. The group's treaty network may be affected by renegotiations or by the Mainland's evolving beneficial-ownership guidance. None of these developments require a full restructuring on each occasion, but they do require a periodic review to confirm that the documented position remains defensible.

Decision checklist: questions to settle before committing

The following questions represent the minimum threshold a foreign group should be able to answer, in writing, before committing to a Hong Kong holding, trading, or financing structure.

• Where do the income-generating activities for each material income stream take place, as a matter of operational fact rather than contractual form?
• Does any income stream fall within the categories caught by the FSIE regime – dividends, interest, equity gains, or IP income – and if so, which substance or participation condition applies?
• Does the group meet the Pillar Two revenue threshold, and if so, what is the projected effective rate for the Hong Kong entities?
• Is there a Mainland China interface, and if so, has the transfer-pricing position been considered alongside the Hong Kong source analysis?
• Does the group intend to claim treaty benefits on income flowing through Hong Kong, and if so, does the Hong Kong entity satisfy the management-and-control and beneficial-ownership conditions?
• What documentation exists – or needs to be created – to support the source and substance position at the point of an IRD enquiry?
• When was the source position last reviewed, and have any operational changes occurred since that review?

If any of these questions cannot be answered with confidence, the risk is not theoretical. A group that cannot demonstrate the factual basis for its source position is exposed to a reassessment of its entire Hong Kong profits tax position for open years. The remediation cost – in tax, penalties, and management time – is invariably higher than the cost of a structured review before the position is taken.

What foreign counsel and in-house teams frequently get wrong

Counsel who have been trained in European or North American tax systems frequently approach Hong Kong with a residence-based mental model. They ask: where is the company incorporated, and what is the rate? Those are the wrong first questions in a territorial system. The right first question is: where did the profit arise? That reorientation takes longer than it should, and the delay creates exposure during the period when the structure is live but the source analysis has not been completed.

A related error is treating the FSIE regime as a discrete compliance matter rather than a structural one. The regime's substance conditions are not a box-ticking exercise; they determine whether the holding layer of a group is within or outside Hong Kong tax. A group that sets up a Hong Kong holding company to receive dividends from its Asian subsidiaries, without first mapping the FSIE conditions, may find that the holding company is taxable on those dividends at 16.5% – the opposite of the intended outcome.

We also see in-house teams conflate the tax and corporate-law analyses. The question of whether a company is a valid Hong Kong entity under the Companies Ordinance is separate from the question of whether its profits are taxable in Hong Kong. A company can be perfectly well constituted and nonetheless have an entirely Hong Kong-sourced profit base. The converse is equally true. Cross-border tax counsel and corporate counsel need to share the same factual picture; in our experience, they frequently do not.
