Federal Commissioner of Taxation v Murphy

The Federal Commissioner of Taxation (the Commissioner) appealed to the High Court of Australia against a decision of the Supreme Court of New South Wales concerning the tax liability of Mr. Murphy. The dispute centred on whether certain payments received by Mr. Murphy constituted assessable income under the *Income Tax and Social Services Contribution Assessment Act 1936* (Cth) (the Act).

The High Court was required to determine whether the payments received by Mr. Murphy were of a capital nature, and therefore not assessable income, or whether they were income according to ordinary concepts and usages of mankind, or otherwise fell within the specific provisions of the Act that defined assessable income. A key question was the characterisation of the payments in the context of Mr. Murphy's business activities and the agreements under which the payments were made.

The Court analysed the nature of the agreements and the payments received, considering whether they represented a once-and-for-all return of capital or a profit derived from the carrying on of a business. Applying established principles of income tax law, the Court distinguished between receipts which are the product of a business and those which are a realisation or change of an asset. The Court found that the payments were not of a capital nature but were income derived from the carrying on of Mr. Murphy's business.

The High Court allowed the Commissioner's appeal, finding that the payments were assessable income.
