Federal Wharf Company Limited v Deputy Federal Commissioner of Taxation

The Federal Wharf Company Limited appealed to the High Court of Australia against assessments for Federal income tax made by the Deputy Federal Commissioner of Taxation for South Australia. The dispute concerned whether sums paid to the company under section 26 of the Harbors Act 1913 (SA) were to be treated as income for the purposes of the Income Tax Assessment Acts 1915-1921 and 1922-1928. Section 26 stipulated that interest, calculated from the date the Minister took occupation of compulsorily acquired property until compensation was paid, was to be added to the compensation amount.

The primary legal issue before the court was whether the interest payable under section 26 of the Harbors Act 1913 (SA) constituted income for the purposes of the relevant Commonwealth income tax legislation. The taxpayer contended that these sums were not income but rather an integral part of the compensation intended to place the company in the same financial position as if its land had not been acquired. The Commissioner, conversely, treated these interest payments as assessable income.

Rich J. held that the interest payable under section 26 was indeed income. His Honour reasoned that the interest was calculated and payable in respect of time, commencing from the date the owner was deprived of the profitable enjoyment of their property until the compensation, representing the capital value, was paid. This characterisation aligned with the principle established in *Hudson's Bay Co. v. Thew*, where interest on the balance of purchase-money was considered income. The court distinguished the present case from *Commissioners of Inland Revenue v. Ballantine*, where interest included within damages was not treated as taxable interest because it was merely a method of quantifying the loss of use of money over time, rather than true interest. In contrast, the interest under section 26 was seen as recompense for the loss of the use of capital during the period before the capital itself was restored through compensation.

The appeal was dismissed, and the company was ordered to pay the costs of the Deputy Federal Commissioner of Taxation.
