Federal Commissioner of Taxation v Adelaide Electric Supply Co Ltd

The Federal Commissioner of Taxation appealed to the Full Court of the High Court of Australia against a decision of Dixon J. concerning the assessment of war-time company tax for the Adelaide Electric Supply Company Limited. The dispute centred on the calculation of "capital employed" for tax purposes, specifically how to treat the company's paid-up capital, which was primarily denominated in sterling but used in Australia. The company, incorporated in Great Britain, had paid up £3,000,000 in sterling before 1930, when Australian and British currency were of equal value. Subsequently, the Australian dollar depreciated, making £1 sterling equivalent to £1.25 Australian. The company also issued shares for which £625,000 was paid in Australian currency after 1931.

The legal issue before the court was whether the £3,000,000 of sterling capital, used in Australia, should be converted into Australian currency at the rate of exchange prevailing during the relevant accounting periods for the purpose of calculating "capital employed" under the War-time (Company) Tax Assessment Act 1940-1944. The Commissioner contended that this capital should be treated as Australian currency from the outset, given its use in Australia and the absence of exchange rate differences at the time of subscription. The company argued, and Dixon J. had held, that the sterling capital should be converted to its Australian currency equivalent at the time of the accounting periods.

The Full Court, affirming the decision of Dixon J., held that for the purposes of the War-time (Company) Tax Assessment Act, the "capital paid up" must be expressed in Australian currency. The court reasoned that all components of the "capital employed" calculation under section 24 of the Act, including accumulated profits and reserves, were required to be in Australian currency. Therefore, the sterling paid-up capital of £3,000,000 needed to be converted to its Australian equivalent of £3,750,000 using the rate of exchange applicable during the relevant accounting periods. The court rejected the Commissioner's argument that the capital should be treated as Australian currency from the time of subscription, finding that the Act's calculation method required a uniform currency for all elements. The court also dismissed a further contention by the Commissioner that a supposed loss of £750,000 due to currency fluctuations should be accounted for in the balance sheet, stating that such a loss was contingent and did not affect the calculation of accumulated profits for tax purposes.

The appeal by the Federal Commissioner of Taxation was dismissed.
