Citibank Ltd v Commissioner of Taxation; Citicorp Finance Pty Ltd v Commissioner of Taxation; Citicorp Wholesale Pty Ltd v Commissoner of Taxation

Citibank Ltd, Citicorp Finance Pty Ltd, and Citicorp Wholesale Pty Ltd (the applicants) sought special leave to appeal to the High Court of Australia against decisions of the Commissioner of Taxation (the respondent). The core dispute concerned whether certain transactions, structured as commercial leases, should be characterised as income according to ordinary concepts for taxation purposes. The applicants argued that the commercial reality and substance of these transactions differed from their legal form, and this distinction was critical to determining their taxability.

The legal issue before the Court was whether, in assessing whether a transaction constitutes "income according to ordinary concepts" for tax purposes, one should focus on the legal characterisation of the transaction or its commercial substance. The applicants contended that while the transactions were legally structured as leases, their commercial reality, particularly in the context of a bank financing vehicle acquisitions, meant they should not be treated as income in the ordinary sense. They distinguished this situation from cases involving sham transactions or mere labelling, asserting that the legal form of a lease was not in dispute, but rather its tax treatment given its commercial operation.

The applicants' submission highlighted that their client, a bank, engaged in these transactions not as a car dealer but as a financier. The commercial leases were used as a vehicle for financing the acquisition of cars by customers. While legally these were leases with the bank as lessor and the customer as lessee, with an option to purchase at a residual value at the end of the term, the applicants argued that the commercial necessity for the lessor to always offer the vehicle to the lessee at the residual value, regardless of its actual market worth, was a crucial factor. This commercial reality, they submitted, meant that the transaction, despite its legal form as a lease, should be viewed differently for taxation purposes, taking into account its underlying commercial substance.
