Intra-Group Transactions in Hong Kong Offshore Income Exemption: Offshore Exemption Conditions for Intra-Group Service Fees

The Inland Revenue Department’s (IRD) tightening of the offshore income exemption (OIE) regime, effective from 1 January 2023 under the Inland Revenue (Amendment) (Taxation on Specified Foreign Income) Ordinance 2022, has fundamentally altered the tax treatment of intra-group service fees for Hong Kong entities. Prior to this amendment, a Hong Kong company receiving fees from a related foreign entity for management, administrative, or technical services could successfully claim an offshore exemption if the services were performed entirely outside Hong Kong. The 2023 legislative change, driven by the European Union’s (EU) 2021 review of Hong Kong’s preferential tax regimes, now subjects certain passive and active income streams—including intra-group service fees—to a new economic substance test. For Hong Kong-headquartered multinational enterprises (MNEs) and family offices with cross-border operations, the distinction between a taxable onshore service fee and an exempt offshore one is no longer a simple matter of the “place of performance” test. The new rules require a rigorous analysis of the service recipient’s jurisdiction, the nature of the income, and the Hong Kong entity’s operational substance. This article examines the specific conditions under which intra-group service fees can still qualify for the offshore exemption post-2023, the documentation required to satisfy the IRD, and the interplay with the new foreign-sourced income exemption (FSIE) regime.

The Legislative Shift: From Territorial Source to Economic Substance

The 2023 amendment to the Inland Revenue Ordinance (Cap. 112) (IRO) represents the most significant change to Hong Kong’s territorial source principle in decades. The EU’s 2021 report on Hong Kong’s tax regime for offshore income identified the lack of economic substance requirements for passive income as a potential “harmful tax practice.” In response, the Hong Kong government introduced the FSIE regime, which now applies to four specified types of foreign-sourced income: interest, dividends, disposal gains, and income from intellectual property. Critically, intra-group service fees—while not explicitly listed as a “specified foreign income” category—are now subject to a new anti-abuse provision under IRO s. 15(1)(a) if they are derived from a related party in a jurisdiction that does not impose a tax of at least 15% on the income.

The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 53, issued in December 2022, clarifies that intra-group service fees will be deemed to be derived from Hong Kong—and thus fully taxable—if the service recipient is a related person located in a jurisdiction where the income is not subject to an effective tax rate of at least 15%. This is a direct application of the OECD’s Pillar Two global minimum tax rules, albeit adapted for Hong Kong’s territorial system.

Related Person Definition: Under IRO s. 15(1)(a), a “related person” includes a person that controls the taxpayer, is controlled by the taxpayer, or is under common control with the taxpayer. Control is defined as direct or indirect ownership of at least 25% of the voting power or capital.
The 15% Test: The IRD will examine the effective tax rate paid on the service fee in the recipient’s jurisdiction. If the recipient is in a jurisdiction with a headline corporate tax rate below 15% (e.g., the UAE at 9% for most entities, or Bermuda with 0%), the Hong Kong entity cannot claim the offshore exemption. For jurisdictions with a high headline rate but specific exemptions or deductions that bring the effective rate below 15%, the same consequence applies.
Practical Consequence: A Hong Kong management company charging service fees to a related BVI operating company will now need to demonstrate that the BVI entity pays at least 15% effective tax on those fees. Since the BVI has no corporate income tax, this is impossible. The Hong Kong entity will therefore be taxed on the service fee at the standard 16.5% profits tax rate.

For intra-group service fees paid by unrelated parties, the traditional “place of performance” test under IRO s. 14 continues to apply. The IRD’s longstanding position, established in CIR v. Hang Seng Bank Ltd (1990) 2 HKTC 389, is that the source of a service income is determined by where the services are physically performed. However, the 2023 amendment introduces a rebuttable presumption: if the service recipient is a related party, the income is presumed to be sourced in Hong Kong unless the taxpayer can prove otherwise.

Documentation Requirements: To rebut the presumption, the taxpayer must provide:
- A service agreement specifying the location of performance.
- Timesheets or logs showing that the key personnel performed the services outside Hong Kong.
- Evidence that the service recipient had no Hong Kong presence or involvement in the service delivery.
- A transfer pricing study demonstrating that the fee is arm’s length, compliant with the OECD Transfer Pricing Guidelines.

The FSIE Regime and Intra-Group Service Fees: A Layered Analysis

The FSIE regime applies to “specified foreign income” (SFI), which does not include service fees per se. However, the IRD has taken the view that if an intra-group service fee is structured to resemble a passive income stream—for example, a royalty for the use of intellectual property embedded in a service—it may be recharacterized as SFI and subjected to the FSIE’s economic substance requirements.

Recharacterization Risk for Bundled Service Fees

A common planning strategy involves bundling management fees with a nominal royalty for the use of a trademark, brand name, or software. The 2023 amendment explicitly targets this practice. Under IRO s. 15(1)(b), any income that is “derived from or in connection with” the use of intellectual property by a related person is treated as SFI. The IRD’s DIPN No. 53 states that the IRD will look through the form of the arrangement to the substance.

The Substance Requirement: For SFI (including recharacterized service fees), the Hong Kong entity must demonstrate that it has adequate economic substance in Hong Kong. This means:
- A fixed place of business in Hong Kong (e.g., a physical office, not a virtual address).
- A sufficient number of qualified employees (full-time, with relevant expertise).
- A minimum level of operating expenditure (the IRD has not published a specific threshold, but a rule of thumb from the 2022 legislative committee discussions was HKD 2 million per annum for a single entity).
The Consequence of Failure: If the substance requirement is not met, the income is deemed to be sourced in Hong Kong and taxed at 16.5%. There is no penalty or interest for a genuine failure to meet the substance test, but the tax liability is immediate.

The “Adequate Substance” Test for Service Companies

The IRD has issued a non-exhaustive list of factors it will consider when assessing whether a service company has adequate substance:

Employment: The number of full-time employees in Hong Kong who are directly involved in providing the services. Part-time or outsourced staff will not count.
Premises: The size and nature of the office space. A co-working space with a hot desk is unlikely to be considered adequate.
Decision-Making: Where the strategic decisions regarding the service provision are made. If the Hong Kong entity is merely executing instructions from a parent company in a low-tax jurisdiction, the substance test will fail.
Expenditure: The level of operating expenditure incurred in Hong Kong. A company with HKD 5 million in service fee income but only HKD 100,000 in Hong Kong expenses will face scrutiny.

Transfer Pricing Implications and Documentation

The 2023 amendment does not change Hong Kong’s transfer pricing rules, which are codified in IRO s. 50AA and follow the OECD Transfer Pricing Guidelines. However, the IRD has increased its scrutiny of intra-group service fees, particularly those with a cross-border element. The IRD’s 2024 Annual Report noted that transfer pricing adjustments were the second most common adjustment in field audits, after offshore claims.

The Arm’s Length Principle for Service Fees

Under IRO s. 50AA, the IRD may adjust the profits of a Hong Kong entity if the intra-group service fee is not at arm’s length. The OECD’s 2022 “Guidance on the Application of the Arm’s Length Principle to Intra-Group Services” provides the framework. For Hong Kong entities, the key considerations are:

Benefit Test: The service must provide a “real and identifiable benefit” to the recipient. A general management fee for “overall supervision” will likely fail this test.
Cost-Plus Method: For routine services (e.g., accounting, IT support), the cost-plus method is typically used. A mark-up of 5-10% is common for low-value-adding services, but the IRD may challenge if the mark-up exceeds 15% without justification.
Documentation: Hong Kong entities with turnover exceeding HKD 100 million must prepare a Master File and Local File under the OECD’s Country-by-Country (CbC) Reporting framework. For smaller entities, a simple transfer pricing study is recommended.

The 2024 Transfer Pricing Audit Focus

The IRD’s Transfer Pricing Investigation Unit has been actively auditing intra-group service fee arrangements since 2023. The 2024 audit cycle focused on:

HK-to-Mainland China Service Fees: The IRD and the State Taxation Administration (STA) have a joint audit program under the US-Hong Kong Tax Information Exchange Agreement (TIEA). The STA has flagged Hong Kong service companies that charge fees to Mainland entities without demonstrating the benefit.
HK-to-BVI/Cayman Service Fees: As noted above, these are now almost impossible to defend under the 15% effective tax rate test. The IRD is issuing tax assessments for 2023/24 onwards.

Planning Considerations for Family Offices and MNEs

For family offices and MNEs with Hong Kong service companies, the 2023 amendment requires a strategic reassessment. The low-tax era for intra-group service fees in Hong Kong is effectively over for related-party transactions with entities in zero-tax jurisdictions.

Relocate the Service Recipient: If the related party is in a zero-tax jurisdiction, consider moving the service recipient to a jurisdiction with a corporate tax rate of at least 15% (e.g., Singapore at 17%, or a Hong Kong subsidiary that is itself subject to tax).
Increase Hong Kong Substance: For the Hong Kong entity to retain the offshore exemption for unrelated party fees, it must have genuine substance. This means hiring local staff, leasing a physical office, and ensuring that key decisions are made in Hong Kong.
Elect for Taxation: If the 15% threshold cannot be met, the Hong Kong entity may elect to be taxed on the service fee at 16.5%. This may be beneficial if the foreign jurisdiction allows a foreign tax credit for the Hong Kong tax paid.
Use a Hong Kong Holding Company: For family offices, a Hong Kong holding company that owns shares in operating subsidiaries can charge a management fee to those subsidiaries. If the subsidiaries are in jurisdictions with a 15%+ tax rate, the fee can still be offshore-exempt, provided the holding company has substance.

The Exit Tax Warning for US Persons

For US citizens or Green Card holders living in Hong Kong who control a Hong Kong service company, the 2023 amendment creates a potential US tax exposure. Under IRC § 877A, a US person who relinquishes citizenship or terminates long-term residency may be subject to an exit tax if their net worth exceeds USD 2 million or their average tax liability exceeds a threshold (USD 201,000 for 2024). If the Hong Kong service company is a “controlled foreign corporation” (CFC) under IRC § 957, the US person may already be subject to GILTI (Global Intangible Low-Taxed Income) tax on the service fee income. The 2023 amendment does not change the US tax treatment, but it increases the Hong Kong tax cost, which may reduce the overall effective tax rate and potentially trigger US Subpart F income.

Key Takeaways

The 15% effective tax rate threshold is the new gatekeeper: Any intra-group service fee paid by a related party in a jurisdiction with an effective tax rate below 15% is now automatically deemed Hong Kong-sourced and taxable at 16.5%, regardless of where the services are performed.
Documentation is no longer optional: A transfer pricing study, service agreement, and substance documentation (employment records, lease agreements, board minutes) must be prepared before the IRD issues an inquiry. The IRD’s 2024 audit cycle has already begun.
Bundled service fees with IP elements face recharacterization: If a service fee includes a royalty or license fee for intellectual property, it will be treated as specified foreign income under the FSIE regime, requiring the Hong Kong entity to demonstrate adequate economic substance.
Family offices must reconsider Hong Kong service company structures: The traditional model of a Hong Kong management company charging fees to a BVI or Cayman holding company is no longer tax-efficient. Relocating the service recipient to a 15%+ jurisdiction or electing for Hong Kong taxation may be necessary.
US persons face a double tax risk: The 2023 amendment increases Hong Kong tax liability for US-controlled Hong Kong service companies, but it does not eliminate the US GILTI or Subpart F exposure. A coordinated US-HK tax plan is essential.
