Australia's Federal Court upheld an AUD 173.3 million tax assessment against Hilton International Australia for its 2015 hotel sale restructuring. The ruling clarified that Part IVA tax law permits multiple reasonable alternative transactions for comparison, rejecting Hilton's argument for a single preferred counterfactual. The decision reinforces that alternative postulates cannot themselves constitute tax-avoidance schemes.
The Federal Court of Australia rejected Hilton International Australia Pty Ltd’s challenge to the Commissioner of Taxation on 9 September 2026 (Case: Hilton International Australia Pty Ltd v Commissioner of Taxation (No 2) [2026] FCA 1325). Justice Younan upheld the Commissioner’s decision to add AUD 173,300,032.00 to the company’s assessable income for the 2015 income year under Part IVA of the Income Tax Assessment Act 1936 (ITAA 1936).
The restructuring sequence
Hilton group entities purchased the Sydney Hilton hotel at 488 George Street in 2000 for approximately AUD 180 million. Three subsidiaries held ownership: Admiral I Pty Ltd (70%), Admiral II Pty Ltd (16.25%), and Admiral III Pty Ltd (13.75%), operating under Admiral Investments Pty Ltd.
On 29 June 2014, the group formed a Multiple Entry Consolidated (MEC) group under Part 3-90 of the Income Tax Assessment Act 1997 (ITAA 1997), with Hilton International Australia Pty Ltd (HIA) as head company. On 24 June 2014, the group incorporated Admiral Holdings Australia Pty Ltd (AHA) as an eligible tier-1 company.
On 1 March 2015, AHA acquired the hotel’s freehold and operational assets for AUD 425 million, satisfied by an intercompany loan note. On 29 April 2015, Hilton Worldwide International Luxembourg Holding S.à.r.l. (HWIH) agreed to sell AHA to Glory Property III Investment Pty Ltd, completing on 1 July 2015. Glory Property III paid AUD 29,021,785.50 for the AHA share and AUD 420 million to HIA to discharge the intercompany loan, totalling approximately AUD 442 million.
Tax dispute and court decision
Under Subdivision 719-K of the ITAA 1997, AHA’s tax cost base was reset upon leaving the MEC group. HWIH reported a net capital gain of only AUD 21,010,283, while HIA recorded zero taxable gain. The Commissioner applied section 177F, determining HIA obtained a tax benefit.
HIA argued that Part IVA requires identifying a single most reasonable alternative transaction. The Federal Court rejected this interpretation. Justice Younan held that section 177CB(3) permits multiple reasonable alternatives. The Court examined four possible structures. Three satisfied reasonableness and each generated the same AUD 173,300,032.00 taxable gain to HIA.
The first alternative involved direct asset sale to Glory Property III for approximately AUD 449 million, producing AUD 173,300,032.50 taxable gain to HIA. The Court accepted this as reasonable and reflective of standard Australian hotel market practice.
The second alternative examined a share sale of Admiral Investments Pty Ltd for approximately AUD 449 million, generating the same AUD 173,300,032.50 gain to HIA. The Court found it reasonable, though noted AIPL’s 14-year history made it less preferred.
The third postulate involved a new entity acquiring assets and selling shares for approximately AUD 449 million, also producing AUD 173,300,032.50 to HIA. The Court accepted this alternative as simpler and debt-free.
HIA’s proposed alternative involved converting debt to AUD 420 million share capital before sale, resulting in zero gain to HIA but AUD 113 million to HWIH. The Court rejected this entirely, holding that an alternative postulate cannot itself constitute a Part IVA tax-avoidance scheme. Using such a scheme as comparison would create circular reasoning and defeat section 177C’s purpose.
Legal precedent and dominant purpose
The Federal Court applied Commissioner of Taxation v PepsiCo Inc [2025] HCA 30. The High Court established that alternative postulates must represent reliable predictions grounded in commercial and economic reality. This decision clarifies that while PepsiCo sets the reasonableness threshold, it does not mandate a single most reasonable option when multiple alternatives satisfy that threshold.
The Court determined the scheme’s dominant purpose was obtaining the tax benefit. Although the transaction delivered genuine commercial benefits including favourable sale terms and 50-year management rights, these outcomes did not explain the specific structure chosen. Investment Committee records referenced minimising “tax leakage” and maximising proceeds to reduce corporate debt. Hilton Group’s strong bargaining position secured the high price and favourable terms, not the tax-driven structure.
Final ruling
The Federal Court dismissed Hilton International Australia Pty Ltd’s appeal with costs. The Commissioner’s application of section 177F to include AUD 173,300,032.00 in HIA’s assessable income for the 2015 income year stands upheld.
The judgment establishes that Part IVA analysis permits multiple reasonable alternative postulates without requiring identification of a single preferred counterfactual. However, alternative postulates themselves must not constitute tax-avoidance schemes, and the dominant purpose test remains central to Part IVA application.
Hilton International Australia Pty Ltd retains the option to pursue an appeal to the Full Federal Court.
