Glennan v Commissioner of Tax

Glennan (the taxpayer) appealed to the High Court of Australia against a decision of the Full Federal Court, which had affirmed a decision of a single judge of that court. The dispute concerned the deductibility of certain expenses incurred by the taxpayer in relation to a property development project. The Commissioner of Taxation disallowed these deductions, and the taxpayer sought to have this decision overturned.

The primary legal issue before the High Court was whether the expenses incurred by the taxpayer were of a capital nature, and therefore not deductible under section 8-1 of the *Income Tax Assessment Act 1997* (Cth), or whether they were incurred in gaining or producing assessable income, making them deductible. Specifically, the court had to consider the application of the "profit-making undertaking or scheme" principle in determining the character of the expenditure.

The High Court, in dismissing the appeal, applied established principles regarding the distinction between capital and revenue expenditure. Gleeson CJ and Callinan J both found that the expenses were incurred in the course of establishing or enhancing a capital asset, rather than in the day-to-day operations of a business. Their Honours considered that the taxpayer's activities were directed towards a single, large-scale undertaking with the object of realising a capital profit from the sale of the developed property. Consequently, the expenditure was held to be of a capital nature and not deductible. The appeal was dismissed.
