Australia on Friday won a landmark court ruling against Singapore Telecommunications, a victory in the country’s battle against tax avoidance by multinational companies through cross-border financing arrangements. The Federal Court of Australia on Friday dismissed the company’s appeal of a tax assessment related to the acquisition financing of Singtel Optus in 2001. Transactions between two wholly owned Singtel units “differed from those which might be expected to operate between independent enterprises dealing wholly independently with one another,” Judge Mark Kranz Moshinsky wrote for the court. Tax experts warned in the aftermath of the decision that multinationals should expect scrutiny on intragroup financing that doesn’t appear to have taken place at arm’s length – as if it were done between two unrelated parties. Asia’s digital economy is booming. So why is Singtel struggling? The arm’s-length principle is an often-contentious aspect of transfer pricing rules that govern transactions between companies within the same multinational group to make sure they aren’t abused for tax reasons. The Australian Tax Office “has had a laser focus on multinationals’ cross-border financing for many years now,” said Angela Wood, Melbourne-based tax partner at law firm Clayton Utz. “Transfer pricing, particularly for related-party financing, has been the single most important focus area for the ATO in recent times.” The case stretches back to Singtel’s 2001 purchase of Cable and Wireless Optus Ltd, which operated one of Australia’s largest telecommunications businesses, known locally as Optus. Domestically incorporated Singapore Telecom Australia Investments (STAI) subsequently issued shares and loan notes under a loan note issuance agreement (LNIA) to British Virgin Islands-registered subsidiary Singtel Australia Investments (SAI). STAI became a wholly-owned subsidiary of SAI in 2002, issuing loans and later paying interest to SAI, which is tax resident in Singapore. Both entities have been entirely owned by the parent company Singtel of Singapore.

In October 2016, the Australian Tax Commissioner contested tax deductions claimed for interest paid on the loans in the tax years ending March 31 2010, 2011, 2012, and 2013. This assessment meant STAI had fewer losses to carry forward for tax purposes from 2010, ultimately meaning it would see an increased taxable income of just under A$895 million (US$640 million). The primary tax would be A$268 million. In December 2016, STAI lodged objections to the amended assessments, which the commissioner disallowed in 2019. STAI’s appeal against the commissioner’s decisions was the case heard Friday. In December 2016, STAI lodged objections to the amended assessments, which the commissioner disallowed in 2019. STAI’s appeal against the commissioner’s decisions was the case heard Friday. Singapore Telecommunications Ltd said in a statement: “After seeking to settle this matter with the ATO in good faith and failing to reach an agreement as to the application of the law, STAI sought clarity from the court process”. Singtel noted that STAI’s holding company, SAI, would be entitled to a corresponding refund of withholding tax estimated at A$89 million. Wood and other experts predicted that other significant transfer pricing litigation may arise over time -and these could take years to resolve, in or out of court. Singtel has 28 days within which to file an appeal, Wood said. “The Singtel Group will consider the details of today’s judgment, explore available options and determine next steps,” the company said Friday. “It will also ensure material updates are provided to investors on a timely basis.” It is committed to complying with tax obligations in markets where it has operations, it said, and noted that STAI is a significant taxpayer in Australia. The ATO didn’t immediately respond to a request for comment.
