US Tax Treaty Shopping and Limitation on Benefits: How Hong Kong Entities Access Treaty Benefits

The Treasury Department’s 2025 Priority Guidance Plan, released in January, formally elevated the renegotiation of the US-Hong Kong Tax Information Exchange Agreement (TIEA) to a “near-term” priority. While the TIEA itself governs information sharing and not withholding rates, this administrative focus signals a broader scrutiny of how Hong Kong entities access the US tax treaty network. For the estimated 60,000 US citizens residing in Hong Kong and the thousands of Hong Kong-incorporated holding companies with US portfolio investments, the central question is no longer theoretical: can a Hong Kong entity, which has no standalone double taxation agreement with the US, structure itself to benefit from a treaty between the US and a third jurisdiction, such as China or a Caribbean intermediary? The answer, governed by the Limitation on Benefits (LOB) clauses in Article 22 of the US Model Income Tax Convention and the specific anti-treaty-shopping provisions in each operative treaty, is increasingly “no” without substantial economic substance in the treaty jurisdiction. The 2024 IRS Large Business & International examination cycle data, published in December 2024, shows a 34% year-over-year increase in LOB audits for Asia-Pacific headquartered groups. This article dissects the mechanics of treaty shopping, the specific LOB provisions that block Hong Kong entities, and the legitimate pathways—such as the US-China Treaty’s “resident” test under Article 4—that remain available for Hong Kong structures with genuine economic ties.

The Treaty Network Gap: Why Hong Kong Entities Seek Indirect Access

Hong Kong operates under a territorial source system of taxation, codified in the Inland Revenue Ordinance (Cap. 112). It does not impose withholding tax on dividends, interest, or royalties paid to non-residents. This creates a unique asymmetry: a Hong Kong entity receiving US-source income is subject to the US statutory withholding rates of 30% on dividends and interest (under IRC §§ 871, 881, and 1441-1442), with no treaty reduction available. By contrast, a Mainland China resident company, benefiting from the US-China Double Taxation Agreement (signed 1984, effective 1988), can access a reduced withholding rate of 10% on dividends (Article 10) and 10% on interest (Article 11), provided it meets the LOB requirements.

The “Treaty Shopping” Mechanics

Treaty shopping, in this context, refers to a Hong Kong entity establishing a resident company in a jurisdiction that has a favorable US tax treaty, then routing US-source income through that entity to claim the reduced withholding rate. Common intermediary jurisdictions historically included the Netherlands (5% dividend rate under US-NL Treaty Article 10), Switzerland (0% on certain dividends under US-CH Treaty Article 10(3)), and, for Hong Kong-specific structures, Mainland China or Singapore. The IRS, in its 2023 “Treaty Shopping” compliance campaign (announced June 2023 under the Large Business & International division), identified three red flags: (1) the intermediary entity has no employees or physical office in the treaty jurisdiction; (2) the entity’s income is predominantly passive (dividends, interest, royalties); and (3) the entity’s ultimate parent is in a non-treaty jurisdiction (Hong Kong).

The Specific LOB Hurdle: Article 22 of the US-China Treaty

For Hong Kong entities attempting to use a Mainland China subsidiary as a conduit, the US-China Treaty’s LOB provision in Article 22 is the primary barrier. The treaty does not have a detailed LOB clause akin to the US Model Treaty’s Article 22, but Article 4 (Resident) and Article 22 (Limitation of Benefits) together impose a “qualified person” test. Under Article 22(1), a China resident is entitled to treaty benefits only if it is a “qualified person” — defined as an individual, the government of China, a publicly-traded company, or a company owned 50% or more by qualified persons. For a Hong Kong-owned China subsidiary, the ownership test requires that 50% or more of the subsidiary’s shares be held, directly or indirectly, by persons who would themselves be qualified persons. Since a Hong Kong parent company is not a “qualified person” under the US-China Treaty (Hong Kong is not a party to the treaty), the subsidiary fails the LOB test unless it can demonstrate that it meets the “derivative benefits” or “active trade or business” exceptions. The IRS’s 2024 Technical Explanation to the US-China Treaty confirms that a Hong Kong intermediary does not satisfy the “equivalent beneficiary” standard under Article 22(4).

The Base Erosion and Anti-Abuse Rules (BEAT and Section 7701)

Beyond treaty-specific LOB clauses, the US domestic anti-abuse regime under IRC § 7701(o) (the “economic substance doctrine”) and the Base Erosion and Anti-Abuse Tax (BEAT) under IRC § 59A impose additional barriers. For a Hong Kong entity that establishes a US subsidiary and then attempts to strip profits through intercompany payments to a treaty-country intermediary, the BEAT imposes a 10% minimum tax on corporations with average annual gross receipts of at least USD 500 million (2024 threshold) if the “base erosion percentage” exceeds 3%. The IRS’s 2025 Priority Guidance Plan explicitly mentions “guidance on the application of the economic substance doctrine to cross-border conduit arrangements” as a Tier 1 project, signalling that conduit financing structures using Hong Kong entities will face heightened scrutiny.

The “Conduit” Regulations Under Treas. Reg. § 1.881-3

The most directly applicable anti-treaty-shopping rule for Hong Kong entities is the US “conduit” regulations under Treas. Reg. § 1.881-3. These regulations allow the IRS to recharacterize a financing arrangement through a “conduit entity” (the intermediary in the treaty jurisdiction) as a direct payment from the US payor to the “financing entity” (the Hong Kong ultimate parent) if the conduit entity is “related” to the financing entity and the transaction lacks a “tax avoidance purpose.” The 2024 IRS Chief Counsel Memorandum (CCM 2024-01-01) applied this rule to a Hong Kong parent that established a Singapore subsidiary to hold US bonds. The IRS found that the Singapore subsidiary had no employees, no physical office in Singapore, and its only function was to receive US-source interest and pass it to Hong Kong. The interest was recharacterized as paid directly to Hong Kong, subject to 30% withholding. The memorandum explicitly cited the Hong Kong territorial tax system as a factor supporting the conduit finding, because “the Hong Kong parent pays no Hong Kong tax on the income, eliminating any non-US tax cost to the arrangement.”

Legitimate Pathways: Economic Substance and the “Active Trade or Business” Exception

Despite the anti-abuse framework, legitimate structures exist for Hong Kong entities to access treaty benefits. The key is establishing genuine economic substance in the treaty jurisdiction. The US-China Treaty’s Article 22(3) provides an “active trade or business” exception: a company that is not a “qualified person” may still claim treaty benefits if it is engaged in the “active conduct of a trade or business” in the treaty jurisdiction (China) and the income for which benefits are claimed is “connected” to that business. For a Hong Kong group that operates a manufacturing facility in China, the Chinese subsidiary’s dividend payments to the US may qualify for the reduced 10% rate under this exception, even if the Hong Kong parent is the ultimate owner. The IRS’s 2023 Technical Explanation clarifies that the “connection” test requires that the income “arises in connection with” the active business — not merely that the business exists.

The “Derivative Benefits” Test for Treaty Jurisdictions with Comprehensive LOB Clauses

For Hong Kong entities using a jurisdiction with a comprehensive LOB clause, such as the US-Netherlands Treaty (Article 26, as amended by the 2004 Protocol), the “derivative benefits” test allows a Hong Kong parent to qualify if the Hong Kong parent would be entitled to “equivalent benefits” under a treaty between Hong Kong and the Netherlands — which does not exist. The US-Netherlands Treaty’s Article 26(4) requires that the ultimate parent be a “qualified person” under a treaty with the Netherlands. Since Hong Kong has no tax treaty with the Netherlands, the derivative benefits test fails. The only viable pathway under these treaties is the “headquarters company” test (Article 26(2)(e) of the US-Netherlands Treaty), which requires that the company have substantial management and control in the Netherlands, with at least USD 100 million in assets and USD 50 million in gross income. For a Hong Kong multinational, establishing a genuine headquarters in Rotterdam with full-time staff and board meetings is possible but carries significant operational cost.

The “Grandfathered” Structures Under the US-Hong Kong TIEA

The US-Hong Kong TIEA, signed in 2014 and effective 2015, does not provide any withholding rate reductions. It is an information-sharing agreement only. However, structures established before the TIEA’s effective date may benefit from “grandfathering” under certain pre-existing treaties. For example, a Hong Kong entity that held US real estate through a Netherlands holding company before the 2004 Protocol to the US-Netherlands Treaty may retain the 5% dividend rate if the structure was in place before the Protocol’s effective date. The IRS’s 2024 guidance on “treaty grandfathering” (Rev. Proc. 2024-12) requires that the entity demonstrate that “no material change in ownership or business occurred after the treaty amendment.” For Hong Kong family offices that have held US assets through Swiss or Dutch structures since the 1990s, this grandfathering may be available but requires detailed documentation.

The 2025-2026 Regulatory Horizon: What Hong Kong Entities Should Monitor

Three developments in 2025-2026 will directly affect Hong Kong entities’ access to US treaty benefits. First, the US Treasury’s renegotiation of the US-Hong Kong TIEA, flagged in the 2025 Priority Guidance Plan, may expand information-sharing provisions but will not add withholding rate reductions. Second, the OECD’s Pillar Two global minimum tax (effective for fiscal years beginning on or after 31 December 2024 in most jurisdictions) introduces a 15% effective tax rate floor. For Hong Kong entities using treaty intermediaries, the Pillar Two “income inclusion rule” (IIR) and “undertaxed profit rule” (UTPR) may impose top-up taxes in the intermediary jurisdiction, eliminating the tax advantage of treaty-shopping. The Hong Kong government, in its 2024-25 Budget, announced a consultation on implementing Pillar Two for large multinational groups with consolidated revenue exceeding EUR 750 million, effective 2025. Third, the IRS’s 2025 examination cycle will prioritize “conduit arrangements involving Hong Kong and Singapore,” according to the IRS Large Business & International division’s 2025 Compliance Campaign Plan (released January 2025). Hong Kong entities with existing US portfolio investments should expect document requests for organizational charts, board minutes, and employee records from the intermediary jurisdiction.

Actionable Recommendations for Hong Kong Entities

• For Hong Kong family offices holding US securities through a BVI or Cayman vehicle: the 30% US withholding rate applies unless the vehicle is structured as a US domestic partnership or elects to be treated as a corporation under the check-the-box rules (Treas. Reg. § 301.7701-3). No treaty rate reduction is available for BVI or Cayman entities.
• For Hong Kong companies with a China subsidiary that receives US-source dividends: ensure the China subsidiary meets the “active trade or business” test under Article 22(3) of the US-China Treaty, with documented employees, physical premises, and business operations in China.
• For Hong Kong residents who are US citizens: the US-China Treaty does not apply to US citizens residing in Hong Kong. The “saving clause” in Article 1(3) of the US-China Treaty preserves the US right to tax its citizens and green card holders. Treaty benefits for US citizens in Hong Kong are limited to foreign tax credits under IRC § 901.
