Commissioner of Taxation v Day

The Commissioner of Taxation (the Commissioner) appealed to the High Court of Australia against a decision of the Full Federal Court, which had allowed an appeal by Mr. Day (the taxpayer) against an assessment of income tax. The dispute concerned the deductibility of certain expenses incurred by the taxpayer in relation to a property development project.

The High Court was required to determine whether the expenses incurred by the taxpayer, which were primarily related to the acquisition of land and associated costs, were deductible under section 8-1 of the *Income Tax Assessment Act 1997* (Cth) as outgoings incurred in gaining or producing assessable income, or whether they were capital in nature and therefore not deductible. A further issue was whether the expenses were incurred in carrying on a business.

The Court reasoned that the character of the expenditure must be determined by its objective nature and purpose. Applying established principles, the Court found that the expenses were incurred in the process of acquiring a capital asset, namely the land, which was intended to be developed and sold. The expenditure was therefore on capital account and not deductible under section 8-1. The Court also considered the taxpayer's argument that the expenditure was incurred in carrying on a business, but concluded that the activities undertaken did not amount to the carrying on of a business at the time the expenditure was incurred.

The High Court allowed the Commissioner's appeal, setting aside the decision of the Full Federal Court and reinstating the Commissioner's assessment.
