Sanctuary Lakes Pty Ltd v Commissioner of Taxation of the Commonwealth of Australia

Sanctuary Lakes Pty Ltd (Sanctuary Lakes) appealed to the Full Federal Court against a decision of the Administrative Appeals Tribunal (AAT) which affirmed the Commissioner of Taxation's (Commissioner) assessment of additional income tax and penalties. The dispute concerned the deductibility of certain expenses incurred by Sanctuary Lakes in relation to the development and sale of residential land.

The primary legal issue before the Full Federal Court was whether the AAT had erred in law by finding that the expenses incurred by Sanctuary Lakes in relation to the development and sale of residential land were not deductible under section 8-1 of the *Income Tax Assessment Act 1997* (Cth). Specifically, the court considered whether the AAT had correctly applied the principles established in *Sun Newspapers Ltd v Federal Commissioner of Taxation* and *Malouf Investments Pty Ltd v Federal Commissioner of Taxation* in determining the character of the expenditure.

The Full Federal Court held that the AAT had made an error of law. The court reasoned that the AAT had failed to properly distinguish between the expenditure incurred in the course of carrying on a business (which is deductible) and expenditure incurred in the acquisition of capital assets (which is not deductible). The court found that the expenses in question were incurred in the course of Sanctuary Lakes' business of developing and selling land, and therefore were properly deductible under section 8-1. The AAT's characterisation of the expenditure as capital in nature was found to be based on an incorrect application of legal principles.

The appeal was allowed, and the decision of the AAT was set aside. The matter was remitted to the AAT for redetermination in accordance with the Full Federal Court's reasons.
