Perfek Pty Ltd v The Deputy Commissioner of Taxation; Lansell House Pty Ltd v The Deputy Commissioner of Taxation

Perfek Pty Ltd and Lansell House Pty Ltd (the taxpayers) appealed to the High Court of Australia against decisions of the Federal Court of Australia concerning the deductibility of interest expenses incurred by the taxpayers. The Deputy Commissioner of Taxation (the Commissioner) had disallowed these deductions, leading to the dispute. The appeals were heard together by Gummow and Hayne JJ.

The central legal issue before the High Court was whether the interest expenses incurred by the taxpayers on loans used to acquire shares in a company that held income-producing property were deductible under section 8-1 of the *Income Tax Assessment Act 1997* (Cth). Specifically, the court had to determine if the expenditure was incurred in gaining or producing assessable income, or if it was necessarily incurred in carrying on a business for the purpose of gaining or producing assessable income.

The High Court held that the interest expenses were not deductible. Their Honours reasoned that the taxpayers' sole purpose in acquiring the shares was to derive dividends, which were assessable income. However, the acquisition of shares in a company, even one holding income-producing assets, did not constitute carrying on a business for the purpose of gaining or producing assessable income. The taxpayers were investors, not traders, and their activities did not extend beyond the mere holding of shares. Therefore, the expenditure was not "necessarily incurred in carrying on a business" as required by section 8-1. The appeals were dismissed.
