Deputy Federal Commissioner of Taxation v Gold Estates of Australia (1903) Ltd

The Deputy Federal Commissioner of Taxation appealed to the High Court of Australia against a decision of the Supreme Court of Western Australia, which had reduced a land tax assessment. The respondent, Gold Estates of Australia (1903) Ltd, had been assessed for land tax on its land at an unimproved value of £28,478 for the year commencing 1 July 1930. The company objected, arguing the valuation was excessive, and the Supreme Court, applying a 15% deduction to the previous year's assessment based on evidence of a general decline in land values, reduced the assessable value to £22,620.

The legal issues before the High Court were whether the Supreme Court had correctly determined the unimproved value of the land for land tax purposes and, if not, what the correct method of valuation should be. Specifically, the court had to consider the principles for valuing land under the Land Tax Assessment Act 1910-1930, particularly in light of evidence of a declining market and the nature of the respondent's land, which comprised unsold lots from various subdivisions.

The High Court held that the method employed by the Supreme Court, which involved deducting a percentage from a previous year's assessment, was unsound. This approach relied on the presumed correctness of the prior assessment and an assumed uniform decline in values, failing to engage with the specific evidence and principles of valuation. The Court reiterated that the correct method requires considering all evidence on the assumption of a hypothetical willing buyer and a willing seller, negotiating at arm's length, and that the value is what such a buyer would offer to induce a bona fide seller to part with the land. Applying this principle to the materials before it, the High Court determined the unimproved value of the relevant parcels of land to be £23,958. The appeal was allowed, the Supreme Court's order was discharged, and the assessment was remitted to the Commissioner to give effect to the High Court's declared value.
