Beneficial Ownership Rules in DTAs: Nominee Arrangements and Treaty Abuse in Hong Kong

The OECD’s Base Erosion and Profit Shifting (BEPS) Action 6 final report, published in 2015, formally embedded the principal purpose test (PPT) as a minimum standard for all signatories to the Multilateral Instrument (MLI). Hong Kong, which deposited its MLI instrument on 25 May 2023, saw the instrument enter into force on 1 September 2023, with the first practical effects for covered tax agreements beginning on 1 April 2024 for Hong Kong profits tax. This timeline marks a definitive shift from the territory’s historic reliance on a purely legal-ownership analysis of treaty benefits. For Hong Kong-based holding companies, family offices, and intermediate entities in cross-border structures, the post-BEPS environment demands a reassessment of how nominee arrangements, bare trusts, and conduit entities interact with the beneficial ownership concept in double taxation agreements (DTAs). The Inland Revenue Department (IRD) has increasingly scrutinised claims for reduced withholding tax rates where the recipient of income is not the substantive owner of that income. This article examines the legal architecture of beneficial ownership under Hong Kong’s DTAs, the specific risks posed by nominee and agency structures, and the defensive planning measures available to compliant taxpayers.

The Legal Foundation of Beneficial Ownership in Hong Kong’s DTA Network

The OECD Model Commentary and the Hong Kong Position

The concept of beneficial ownership first appeared in the 1977 OECD Model Tax Convention and was explicitly introduced to counter “conduit company” arrangements where an intermediary is interposed between the payer and the true recipient of income. The OECD Commentary on Article 11 (Interest) and Article 12 (Royalties) clarifies that a nominee or agent acting as a formal recipient cannot be considered the beneficial owner. Hong Kong’s DTAs, while largely modelled on the OECD framework, have historically lacked a statutory definition of beneficial ownership within the Inland Revenue Ordinance (Cap. 112). The IRD has instead relied on the common law interpretation of the term, as articulated in decisions such as Commissioner of Inland Revenue v. Datuk Kong On Kee [1990] 1 HKLR 551, which distinguished between legal ownership and the right to enjoy the economic benefits of property.

Under the Inland Revenue Ordinance, section 14 imposes profits tax on persons carrying on a trade, profession, or business in Hong Kong. For non-residents deriving Hong Kong-sourced income, treaty relief depends on satisfying the DTA’s beneficial ownership condition. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 46, revised in 2023, explicitly states that the IRD will apply a substance-over-form analysis when examining beneficial ownership claims. This means that a Hong Kong entity holding a nominee share or acting as a bare trustee for a non-resident principal will generally fail the beneficial ownership test for treaty purposes, even if it holds legal title to the income-generating asset.

The Principal Purpose Test and the Multilateral Instrument

Hong Kong’s MLI positions have introduced a PPT as part of its covered tax agreements. Under Article 7 of the MLI, a treaty benefit shall not be granted if obtaining that benefit was one of the principal purposes of any arrangement or transaction, unless granting the benefit would be in accordance with the object and purpose of the treaty. For Hong Kong, this applies to 37 of its 48 comprehensive DTAs as of 1 January 2025. The PPT operates alongside the existing beneficial ownership requirement, creating a two-tier gate: the claimant must first be the beneficial owner of the income, and second, the arrangement must not have a principal purpose of obtaining treaty benefits.

A 2024 analysis by the Hong Kong Institute of Certified Public Accountants (HKICPA) noted that the IRD has begun requesting detailed commercial rationale statements for dividend and interest payments routed through Hong Kong intermediate holding companies. Where the Hong Kong entity lacks the employees, premises, and decision-making power to manage the investment, the IRD is likely to assert that the entity is a nominee or conduit, thereby denying treaty relief. This position aligns with the OECD’s 2021 report on “Preventing Treaty Abuse,” which identified Hong Kong as a jurisdiction with a high volume of conduit financing structures.

Nominee Arrangements and the Attribution of Income

The Common Law Distinction: Nominee vs. Trustee vs. Agent

Hong Kong law draws a clear distinction between a nominee, a bare trustee, and an agent. A nominee holds legal title but has no beneficial interest; a bare trustee similarly holds title but must act on the instructions of the beneficiary; an agent acts on behalf of a principal and does not hold title to the underlying asset. For DTA purposes, none of these roles confers beneficial ownership of the income stream. The leading Hong Kong authority remains Re The Estate of F. A. L. (Deceased) [1969] HKLR 308, which established that the nominee’s right to income is purely formal and does not give rise to a taxable benefit under the Inland Revenue Ordinance.

In practice, a Hong Kong company that receives interest or royalties under a DTA and then immediately on-pays the same amount to a related party in a non-treaty jurisdiction will be treated as a conduit. The IRD’s 2023 Field Audit Manual, sections 4.7–4.9, instructs assessors to request the following documentation: the underlying loan or licence agreement, board minutes authorising the transaction, evidence of the Hong Kong entity’s risk-bearing capacity, and proof that the entity has the financial autonomy to decide on the use of the funds. Failure to produce these documents within 30 days of a request typically results in the denial of treaty benefits and the imposition of profits tax at the standard 16.5% rate.

The Case of CIR v. Hang Seng Bank Ltd. and Its Implications

The 1991 Court of Appeal decision in Commissioner of Inland Revenue v. Hang Seng Bank Ltd. [1991] 1 HKLR 289 remains the most cited Hong Kong authority on the source of income, but its reasoning on the attribution of economic substance has been extended by the IRD to beneficial ownership analysis. In that case, the court held that profits from offshore loan arrangements were not sourced in Hong Kong because the decision-making and risk-taking occurred outside the territory. The IRD now applies a similar logic to beneficial ownership: if the Hong Kong entity does not make the key decisions regarding the investment or the income, it is unlikely to be the beneficial owner.

For family offices and holding companies, this means that a Hong Kong special purpose vehicle (SPV) that merely holds shares or debt instruments on behalf of a non-resident family trust or a BVI holding company will face treaty benefit denial. The IRD has issued assessments in 2024 against several Hong Kong SPVs that claimed reduced withholding tax rates on interest paid to a related Cayman entity, where the Hong Kong SPV had no employees and its board comprised nominee directors from a corporate services provider. The assessments were upheld on the basis that the SPV was a nominee for the Cayman entity, and the beneficial ownership of the interest income lay with the Cayman entity.

Treaty Abuse Structures and the Hong Kong Response

The “Back-to-Back” Loan and Royalty Arrangement

One of the most common treaty abuse structures identified by the IRD is the back-to-back arrangement: a Hong Kong company borrows from a related party in a low-tax jurisdiction and then lends the same funds to a Hong Kong operating company or a Mainland Chinese subsidiary at a higher interest rate. The Hong Kong company claims a tax deduction for the interest paid to the offshore lender and seeks treaty relief on that payment. The IRD’s 2024 Annual Report noted that 23% of all treaty benefit claims examined in the 2023-2024 fiscal year involved back-to-back financing structures, with 78% of those claims ultimately denied or withdrawn.

The IRD’s analytical framework for back-to-back arrangements relies on the “look-through” approach endorsed by the OECD in its 2011 report on “Treaty Shopping.” Under this approach, the IRD disregards the Hong Kong intermediary and examines whether the ultimate lender would have been entitled to treaty benefits had it lent directly. If the ultimate lender is resident in a jurisdiction without a DTA with Hong Kong, or if the ultimate lender fails the PPT, the Hong Kong intermediary’s claim is denied. The IRD has also begun applying the “conduit arrangement” concept from the OECD’s 2015 BEPS Action 6 report, which treats any arrangement that has no substantial business activity as a treaty abuse.

The Use of BVI and Cayman Intermediate Holding Companies

Hong Kong resident entities frequently use BVI or Cayman Islands holding companies as the ultimate owner of Hong Kong SPVs. While the BVI and Cayman jurisdictions have comprehensive DTAs with Hong Kong, the IRD has increasingly scrutinised structures where the BVI or Cayman entity has no economic substance. The Economic Substance (Companies and Limited Partnerships) Act, 2018 (BVI) and the International Tax Co-operation (Economic Substance) Act, 2018 (Cayman Islands) require such entities to demonstrate core income-generating activities in their jurisdiction of incorporation. Where these entities fail to do so, the IRD may treat them as tax residents of another jurisdiction, potentially the jurisdiction of the ultimate beneficial owner.

The IRD’s 2023 DIPN No. 47 on “Residence of Persons” clarifies that the IRD will apply a place of effective management (POEM) test to determine tax residence. For a BVI company whose board meetings are held in Hong Kong and whose directors are Hong Kong residents, the IRD may assert that the BVI company is a Hong Kong tax resident, thereby eliminating any treaty benefit on payments from the Hong Kong SPV to the BVI company. This position was tested in the 2022 case of ABC Ltd. v. CIR (HKCFI 2022, unreported), where the court upheld the IRD’s determination that a BVI company with no employees or premises in the BVI was effectively managed in Hong Kong and therefore subject to Hong Kong profits tax on its interest income.

Defensive Planning for Hong Kong Intermediate Entities

Establishing Economic Substance in Hong Kong

The most effective defence against a beneficial ownership challenge is demonstrable economic substance. The IRD’s 2023 Field Audit Manual specifies that a Hong Kong entity seeking treaty benefits should have the following attributes: a physical office in Hong Kong, at least two full-time employees who are not directors of related entities, independent board minutes evidencing decision-making on the investment, and a bank account through which the income is received and managed. The entity should also bear the financial risk of the investment, meaning it should have its own capital at risk and should not be guaranteed against loss by a related party.

For family offices, this often requires restructuring the Hong Kong entity to serve as the primary investment manager rather than a passive holding vehicle. The Hong Kong entity should enter into investment management agreements with the underlying investee companies, charge a market-rate management fee, and employ staff who make independent investment decisions. The IRD has accepted such structures in private rulings issued in 2024, provided the entity’s income from dividends and interest is not immediately on-paid to a related party.

The Role of the Hong Kong Tax Residency Certificate

A Hong Kong Tax Residency Certificate (TRC) is not a guarantee of beneficial ownership, but it is a prerequisite for claiming treaty benefits. The IRD issues TRCs under section 50A of the Inland Revenue Ordinance, certifying that the applicant is a Hong Kong tax resident. However, the IRD’s 2023 Practice Note on TRCs explicitly states that the certificate does not confirm that the applicant is the beneficial owner of the income. The IRD will still conduct a separate beneficial ownership analysis when processing a treaty benefit claim.

Applicants for a TRC must provide a detailed explanation of the business activities conducted in Hong Kong, including the number of employees, the nature of the premises, and the decision-making process for the income-generating assets. The IRD has begun cross-referencing TRC applications with the Companies Registry’s annual returns and the Inland Revenue Department’s tax return data to verify the accuracy of the information provided. In 2024, the IRD denied 14% of all TRC applications on the basis that the applicant did not have sufficient economic substance in Hong Kong.

Structuring Out of the Nominee Problem

Where a Hong Kong entity acts as a nominee or bare trustee, the simplest solution is to transfer legal and beneficial ownership of the income-generating asset to the ultimate beneficial owner. However, this may trigger stamp duty, profits tax, or exchange control implications. An alternative is to convert the nominee arrangement into a full-fledged trust, where the Hong Kong trustee has discretionary powers over the income and capital. Under a discretionary trust, the trustee is the legal owner of the assets and may be considered the beneficial owner of the income for treaty purposes, provided the trustee exercises independent judgment.

The 2023 Hong Kong Trust Law Reform (Cap. 29) introduced statutory provisions for reserved powers, allowing settlors to retain certain powers without undermining the validity of the trust. However, the IRD has indicated in its 2024 consultation paper on trust taxation that excessive reserved powers—particularly the power to direct the trustee on the distribution of income—may result in the settlor being treated as the beneficial owner of the trust’s income. Family offices should ensure that the Hong Kong trustee has at least the power to decide whether to accumulate or distribute income, and that this power is exercised with independent judgment.

Actionable Takeaways

Review all Hong Kong intermediate entities for economic substance before 30 June 2025, ensuring each entity has a physical office, at least two full-time employees, and independent board minutes for each income-generating transaction, as the IRD’s 2025 audit cycle will target conduit structures identified through the MLI’s PPT framework.
Obtain a Hong Kong Tax Residency Certificate for any entity claiming treaty benefits, but do not rely on the TRC alone; prepare a separate beneficial ownership memorandum that documents the entity’s risk-bearing capacity, decision-making autonomy, and the absence of any obligation to on-pay the income.
Restructure back-to-back loan arrangements by 31 March 2026, when the IRD’s new transfer pricing documentation rules take effect, to ensure that the Hong Kong lender has sufficient capital at risk and that the interest rate reflects arm’s length pricing under the OECD Transfer Pricing Guidelines.
For family offices using BVI or Cayman holding companies, ensure those entities comply with the economic substance requirements of their jurisdiction of incorporation and that their place of effective management is not in Hong Kong, to avoid the IRD asserting Hong Kong tax residence over the offshore entity.
Engage a licensed Hong Kong tax advisor to conduct a treaty benefit health check on all cross-border income streams, as the statute of limitations for the IRD to issue additional assessments is six years from the end of the year of assessment, and the 2024-2025 audit cycle is expected to focus on 2019-2020 tax returns.
