Revenue Commissioners v Susquehanna International & Ors (Approved)

Factual and Procedural Background

This judgment concerns an appeal by way of case stated from a determination of the Appeal Commissioners in favour of the taxpayers. The appellant, referred to as Revenue, initially declined to grant group relief under section 411 of the Taxes Consolidation Act, 2007 (TCA). The taxpayers, three Irish companies collectively referred to as the taxpayers, appealed successfully before the Appeal Commissioners. The taxpayers are ultimately owned by a Delaware limited liability company (LLC), described as fiscally transparent or a disregarded entity for US tax purposes. The Revenue Commissioners conceded that the LLC is a "company" for the purposes of section 411 but contested its residency for tax purposes under the Double Taxation Agreement (DTA) between Ireland and the United States.

The key factual background involves the tax status of the LLC under US law, where it is disregarded as a separate taxable entity, with its income taxed at the level of its ultimate individual US-resident owners. The central dispute relates to whether the LLC qualifies as a resident of the United States within the meaning of Article 4 of the DTA and whether it is "liable to tax" in the US, which affects the taxpayers' entitlement to group relief in Ireland and the applicability of the anti-discrimination provisions of the DTA.

Legal Issues Presented

1. Whether the fiscally transparent status of the LLC deprives it of the ability to rely on the anti-discrimination provisions of the Double Taxation Agreement (DTA) between Ireland and the United States.
2. Independently of the provisions of the DTA, whether the fiscally transparent nature of the LLC means that the taxpayers are not entitled to group relief under section 411 of the Taxes Consolidation Act, 2007.
3. Whether the Appeal Commissioner erred in law in holding that the LLC was a resident for tax purposes in the United States within the meaning of Article 4 of the DTA.
4. Whether the Appeal Commissioner erred in law in concluding that the taxpayers were entitled to group relief under section 411 of the TCA.

Arguments of the Parties

Appellant's Arguments (Revenue)

• The LLC, as a disregarded entity under US tax law, is not "liable to tax" in the United States within the meaning of Article 4 of the DTA because it is disregarded as a separate taxable entity and has no income tax filing obligations itself.
• The anti-discrimination provisions of the DTA cannot apply unless the LLC is resident in the United States for tax purposes, which it is not.
• The Revenue Commissioners rely on a strict, literal interpretation of the DTA, emphasizing the ordinary meaning of "liable to tax" and the requirement that liability arise "under the laws of that State".
• The Appeal Commissioner erred in attributing to the DTA ancillary purposes, such as mitigating administrative complexities, which are not supported by the text or evidence.
• Revenue accepts that the DTA aims to prevent discrimination but argues that this is limited to the terms set out in the treaty and does not extend to treating the LLC as a resident if it is not liable to tax.
• Reliance on the OECD Commentaries and the DTA Protocol supports the position that fiscally transparent entities like the LLC are not liable to tax and should be treated as disregarded for treaty purposes.
• The taxpayers must establish that the LLC is resident in the United States to claim discrimination under Article 25.4 of the DTA; the residence of the ultimate individual owners is insufficient for this purpose.

Respondents' Arguments (Taxpayers)

• The taxpayers dispute that they must prove the LLC is a resident of the United States under the DTA to succeed.
• If residency is required, the LLC should be considered liable to tax in the US because its income is fully and comprehensively taxed at the member level under US tax law.
• The broad definitions in Article 3 of the DTA, including "nationals of a Contracting State", support a wider interpretation that includes the LLC.
• The anti-discrimination provisions of the DTA are engaged even if the LLC is not directly liable to tax.
• The interpretation that excludes the LLC from residency would lead to a manifestly absurd or unreasonable result, given that it is a body corporate, comparable to an Irish resident company, and its income is taxed within the US tax net.
• They rely on the Canadian decision in TD Securities and other authorities to support a purposive interpretation that treats the LLC as liable to tax for treaty purposes despite its fiscal transparency.
• The DTA Protocol and the objective of preventing discrimination further support their position.

Court's Reasoning and Analysis

The court began by examining the meaning of the phrase "liable to tax" within Article 4 of the DTA, distinguishing it from "subject to tax" by reference to the Weiser case and other authorities. It concluded that "liable to tax" requires an abstract liability to taxation under the domestic laws of the Contracting State. The LLC, as a disregarded entity under US law, is not liable to tax itself but its income is taxed at the level of its members. The court found that this status means the LLC is not "in the tax net" and thus not liable to tax within the meaning of Article 4.

Turning to treaty interpretation principles, the court applied the Vienna Convention on the Law of Treaties and relevant Irish case law, confirming that interpretation must be in good faith according to the ordinary meaning of the treaty terms in context. The court rejected the Appeal Commissioner’s purposive interpretation that sought to treat the LLC as liable to tax to mitigate administrative complexities, noting the absence of evidence supporting this rationale and the lack of such an objective explicitly in the DTA.

The court considered the OECD Commentaries and the DTA Protocol, which consistently treat fiscally transparent entities as not liable to tax and attribute income to the members for treaty purposes. This supported the conclusion that the LLC is not liable to tax.

The court also addressed the anti-discrimination provisions in Article 25, emphasizing that the relevant provisions refer specifically to "residents of a Contracting State" and that the taxpayers must prove the LLC's residency to invoke these protections. The court rejected the argument that the residency of the ultimate individual owners suffices for this purpose, relying on the legal distinction between the entity and its members.

Finally, the court considered and distinguished the Canadian TD Securities decision, finding its reasoning unpersuasive in the present context, particularly because it did not address the anti-discrimination purpose of the treaty and conflated the taxation of the entity with that of its members.

Accordingly, the court found that the Appeal Commissioner erred in law by holding that the LLC was a resident of the United States for treaty purposes and by concluding that the taxpayers were entitled to group relief under section 411 of the TCA.

Holding and Implications

The court's final decision is to SET ASIDE the determination of the Appeal Commissioner in favour of the taxpayers.

This means that the LLC is not a resident of the United States within the meaning of Article 4 of the DTA and is not liable to tax in the United States for treaty purposes. Consequently, the taxpayers cannot rely on the anti-discrimination provisions of the DTA to claim group relief under section 411 of the TCA. The direct effect is that the Revenue Commissioners’ refusal to grant group relief stands. No new precedent beyond the application of existing treaty interpretation principles and tax law was established.
