Australasian Catholic Assurance Co Ltd v Federal Commissioner of Taxation

The Australasian Catholic Assurance Co Ltd (the taxpayer) appealed an income tax assessment by the Federal Commissioner of Taxation (the Commissioner). The dispute concerned the taxability of a profit of £78,649 realised from the sale of fourteen blocks of flats during the 1951 financial year. The taxpayer, whose principal business was life assurance, had acquired these flats between 1934 and 1941 as long-term investments, intending to hold them for approximately thirty years. Economic considerations, including increased maintenance costs and rent control, ultimately dictated the sale of these properties.

The central legal issue before the court was whether the profit derived from the sale of these flats constituted assessable income. Specifically, the court had to determine if the profit was a capital gain or income according to ordinary concepts and the provisions of the *Income Tax and Social Services Contribution Assessment Act 1936-1950*. The taxpayer contended that the profit was a capital gain and fell outside the definition of assessable income, while the Commissioner argued it was income derived from the carrying on of the taxpayer's business.

Menzies J. held that the profit was assessable income. His Honour found that while the flats were not acquired for the primary purpose of profit-making by sale, their sale was an act done in the carrying on of the taxpayer's business. Applying the principles from *Colonial Mutual Life Assurance Society Ltd. v. Federal Commissioner of Taxation* and *Producers' and Citizens' Co-operative Assurance Co. Ltd. v. Federal Commissioner of Taxation*, the court reasoned that enhanced values obtained from the realisation or conversion of investments can be assessable income where the activity is part of the carrying on of a business, rather than merely a change of investment. The court concluded that the sale of these flats, even if prompted by unexpected developments, was an ordinary step in the taxpayer's investment business, and the profit realised was therefore income according to ordinary concepts and the Act.

The appeal was dismissed, with costs awarded to the respondent.
