Multiple Companies Under Two-Tiered Regime: Is Splitting Profits Across Entities Compliant?

The Inland Revenue Department (IRD) has sharpened its focus on corporate structures that appear designed primarily to multiply the benefit of the two-tiered profits tax regime. Since its introduction for the year of assessment 2018/19, the regime has provided a clear tax saving: the first HKD 2 million of assessable profits for a single entity is taxed at 8.25% (half the standard 16.5% rate), with profits exceeding that threshold taxed at the full rate. For the 2025/26 tax year, with the standard rate unchanged, the maximum annual saving per qualifying entity remains HKD 165,000. A business owner operating through five separate companies could, on paper, save HKD 825,000 annually—a figure that has caught the attention of both aggressive planners and the IRD’s field audit teams. The operative question for any Hong Kong taxpayer considering this structure is whether the IRD will treat the multiple entities as a single economic enterprise under the anti-avoidance provisions of the Inland Revenue Ordinance (Cap. 112), specifically sections 61 and 61A. The answer turns not on the number of companies, but on the commercial substance and independent economic activity of each.

The Two-Tiered Regime: Mechanics and the Anti-Avoidance Perimeter

How the Concessionary Rate Applies

The two-tiered profits tax regime, codified in Schedule 8 to the Inland Revenue Ordinance (Cap. 112), applies to all corporations regardless of size. For any qualifying corporation, the first HKD 2 million of assessable profits is charged at 8.25%. The balance is charged at 16.5%. The regime applies per taxpayer entity, not per economic group. This means a group of 10 wholly-owned trading companies, each with HKD 2 million in assessable profits, could collectively pay HKD 1.65 million in profits tax (10 × HKD 2 million × 8.25%), versus HKD 3.3 million if the group were assessed as a single entity (HKD 20 million × 16.5%). The saving of HKD 1.65 million is the arithmetic that drives the structuring question.

The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 60, issued in March 2019, explicitly addresses the splitting of profits. Paragraph 14 states that the IRD will apply the general anti-avoidance provisions where “the sole or dominant purpose” of creating multiple entities is to obtain the two-tiered benefit. The IRD does not need to prove tax avoidance as the only purpose—section 61A of the IRO requires that the transaction be entered into for the “sole or dominant purpose” of obtaining a tax benefit. The burden of proof initially falls on the IRD, but in practice, the taxpayer bears the evidentiary burden of demonstrating commercial rationale.

The Section 61A Trigger: What the IRD Looks For

Section 61A of the IRO empowers the IRD to disregard any transaction that has the effect of reducing a tax liability if the transaction was entered into with the dominant purpose of obtaining a tax benefit. The provision is not limited to artificial schemes. The leading Hong Kong Court of Final Appeal decision in CIR v. Tai Hing Cotton Mill (Developments) Ltd (2007) 10 HKCFAR 393 established that the test is objective: would a reasonable person conclude that the transaction had the dominant purpose of tax avoidance? The IRD’s field audit teams apply this test by examining the following indicia in multiple-company structures:

Commonality of directors, shareholders, and registered address: Identical directors and shareholders across entities, particularly when all companies are registered at the same virtual office address, creates a presumption of artificiality.
Shared operational resources: If the companies share the same office space, the same telephone line, the same bank accounts, or the same employees without arm’s-length cost-sharing agreements, the IRD will argue that the entities are not independent.
Circular or non-arm’s-length transactions: Internal invoicing between related companies that shifts profits to the entity with unused HKD 2 million capacity is a red flag. The IRD will examine transfer pricing documentation under the new transfer pricing regime (sections 50AAF to 50AAJ of the IRO, effective from year of assessment 2022/23).
Absence of separate business operations: If each company does not have its own client base, supplier relationships, and distinct business function, the structure lacks commercial substance.

The 2024/25 IRD Annual Report noted that the department completed 1,200 field audits and investigations, resulting in HKD 1.8 billion in additional tax and penalties. While the report does not break down the figures by anti-avoidance challenge, practitioners report an increase in IRD enquiries into multiple-company structures specifically since 2022.

When Splitting Is Compliant: The Substance Test in Practice

Genuine Business Separation: The Gold Standard

A taxpayer can legitimately operate multiple companies and claim the two-tiered rate for each, provided each entity carries on a genuinely separate business. The operative test is whether each company has its own operational identity, distinct management, and independent economic activity. Consider a Hong Kong property developer who operates three separate lines of business: residential property development (Company A), commercial property leasing (Company B), and property management services (Company C). If each company has its own:

Separate bank accounts and accounting records;
Distinct client contracts and supplier agreements;
Dedicated employees (even if shared under a cost-recovery service agreement);
Separate premises (or a properly documented shared-services arrangement with arm’s-length rent); and
Independent decision-making processes for pricing and contracting,

then the IRD is unlikely to challenge the structure. The key is that the business separation is driven by commercial factors—different risk profiles, different regulatory requirements, different client bases—not by the tax rate differential.

The IRD’s DIPN No. 60 (paragraph 16) explicitly states that “the fact that a taxpayer carries on business through a number of companies does not by itself mean that the arrangement is caught by the anti-avoidance provisions.” The department acknowledges that commercial reasons such as limiting liability for different business lines, accommodating different investor groups, or complying with regulatory requirements are legitimate grounds for using multiple entities.

The Role of Transfer Pricing Documentation

Since the introduction of Hong Kong’s transfer pricing regime in 2018 (fully effective from 2022/23), the IRD has a statutory framework to examine inter-company transactions. If multiple companies share resources—for example, a single administrative team handling accounts for all entities—the cost must be allocated on an arm’s-length basis. The IRD’s transfer pricing guidelines (DIPN No. 59) require that related-party transactions be documented with a written agreement specifying the allocation method, the basis for pricing, and the rationale for the selected transfer pricing method.

For a taxpayer operating three companies from the same office, the following documentation is essential:

A written shared-services agreement between the companies, specifying the services provided (e.g., accounting, IT support, HR) and the allocation key (e.g., proportion of revenue, headcount, or floor space).
Invoices issued between the entities at arm’s-length prices, with supporting calculations.
A transfer pricing analysis demonstrating that the allocation method is consistent with the OECD Transfer Pricing Guidelines and the Hong Kong Inland Revenue Ordinance.

Failure to maintain such documentation does not automatically invalidate the structure, but it significantly weakens the taxpayer’s position if the IRD opens an audit. The IRD can impose penalties of up to 100% of the tax undercharged where there is intentional disregard of the transfer pricing rules.

The IRD’s Enforcement Toolkit: What to Expect in an Audit

The Field Audit Process for Multiple-Entity Structures

The IRD’s field audit teams select cases for review based on risk indicators. For multiple-company structures, the key risk indicators include:

A sudden increase in the number of companies registered by a single beneficial owner;
Companies with identical registered addresses and directors;
Repeated claims of the two-tiered rate by entities with consistently low profits (just under HKD 2 million); and
Returns showing high revenue but low profits, suggesting profit shifting through inter-company charges.

When an audit is opened, the IRD will issue a letter requesting:

The group structure chart showing all related entities, their shareholding, and their business activities.
The financial statements and tax returns for all entities for the years under review (typically the last 6 years, but extendable to 10 years in cases of suspected fraud).
The board minutes and resolutions authorizing the creation of each company and the inter-company transactions.
The service agreements, lease agreements, and other contracts between the related entities.
The transfer pricing documentation for the relevant years.

The IRD will then conduct an interview with the taxpayer or the taxpayer’s representative. The interview is a critical stage—the IRD will probe the commercial rationale for the structure, the decision-making process for pricing, and the actual operational independence of each entity. Inconsistencies between the oral evidence and the documentary evidence can lead to a full-scale investigation.

Penalties and the Statute of Limitations

If the IRD successfully invokes section 61A, the consequence is that the two-tiered rate is denied for all entities, and profits are aggregated and taxed at 16.5% from the first dollar. The IRD will also impose penalties under section 82A of the IRO for incorrect returns. The penalty is typically 3 times the amount of tax undercharged for cases involving intentional evasion, and 1 to 2 times for cases involving negligence.

The statute of limitations for raising an assessment under section 61A is 6 years from the end of the year of assessment in which the tax was undercharged. However, if the IRD can prove fraud or willful evasion, the period extends to 10 years. Given that the two-tiered regime has been in effect since 2018/19, the IRD is currently within the 6-year window for the first years of the regime, and audits opened in 2025 could reach back to the 2019/20 year of assessment.

Practical Structuring: How to Stay Compliant While Optimizing

The Safe Harbour: One Entity, One Business Line

The safest approach for a taxpayer who genuinely has multiple business lines is to operate each distinct business through a separate company, with clear operational separation. The taxpayer should:

Register each company with a different business address (even if the address is a co-working space with separate offices).
Appoint different directors for each company (or at least ensure that the directors have distinct responsibilities and are not merely nominees).
Maintain separate bank accounts, separate accounting records, and separate tax filings for each entity.
Document all inter-company transactions with written agreements and arm’s-length pricing.
Ensure that each company has its own client contracts, supplier relationships, and business licenses.

For a professional practice—for example, a law firm that also operates a consulting business—the separation is commercially justified by different regulatory requirements (the Law Society’s rules on fee-sharing, for instance). The Law Society of Hong Kong’s 2024 Practice Direction on Multi-Disciplinary Practices explicitly permits separate entities for legal and non-legal services, provided the legal entity remains independent. The IRD will respect such regulatory-driven structures.

The High-Risk Zone: Pure Profit Splitting

The structure that the IRD will challenge most aggressively is the creation of multiple companies that all carry on the same business—for example, a trading company that splits its operations into five separate companies, each handling a different product line or geographic market, with all companies sharing the same office, the same staff, and the same bank accounts. The IRD will argue that this is a single economic enterprise artificially divided to multiply the two-tiered benefit.

In such cases, the taxpayer bears a heavy burden to demonstrate commercial substance. The IRD will look for evidence that each company has its own:

Independent decision-making (separate board meetings, separate pricing decisions);
Distinct risk profile (separate insurance policies, separate liability);
Separate operational management (different employees, different managers); and
Independent financing (separate bank loans, separate credit lines).

Without these indicia, the IRD will likely succeed in invoking section 61A.

The Exit Strategy: Voluntarily Disclosing Past Non-Compliance

For taxpayers who have already set up multiple companies without adequate substance, the IRD’s Voluntary Disclosure Programme offers a path to reduced penalties. Under the programme, a taxpayer who voluntarily discloses a tax default before the IRD opens an investigation will have penalties capped at 10% of the tax undercharged (for non-fraud cases) or 30% (for fraud cases). The disclosure must be complete, meaning the taxpayer must provide all relevant information for all years and all entities.

The IRD’s 2024/25 Annual Report recorded 2,800 voluntary disclosure applications, resulting in HKD 420 million in additional tax and HKD 63 million in penalties. The average penalty rate was 15%, significantly lower than the 200-300% imposed in contested cases.

A taxpayer considering voluntary disclosure should:

Compile a complete list of all related entities and their tax returns for the years under review.
Prepare a detailed explanation of the commercial rationale for the structure (if any).
Calculate the tax undercharged (the difference between the 8.25% rate claimed and the 16.5% rate that would have applied if profits were aggregated).
Submit the disclosure in writing to the IRD’s Field Audit Division, with supporting documents.
Engage a licensed tax representative to negotiate the penalty quantum.

The IRD will generally accept a voluntary disclosure if it is made before the taxpayer receives any indication that an audit or investigation has commenced.

Actionable Takeaways

Operate each company with genuine commercial independence: separate bank accounts, separate premises (or documented shared-services agreements), separate employees, and separate client contracts—the IRD will test substance, not form.
Maintain transfer pricing documentation for all inter-company transactions: a written shared-services agreement with an arm’s-length allocation key is the minimum requirement for related entities sharing resources.
Do not create multiple companies solely to multiply the HKD 2 million threshold: the IRD’s anti-avoidance provisions under sections 61 and 61A of the IRO will apply where the dominant purpose is tax benefit, and penalties can reach 300% of the tax undercharged.
Review existing structures before the 6-year statute of limitations expires: the IRD can assess back to 2019/20 for the two-tiered regime, and voluntary disclosure before an audit opens reduces penalties to 10-30% of the tax undercharged.
