Watson v Commissioner of Taxation for Western Australia

The appeal concerned Henry Keith Watson, a public accountant carrying on business in Perth, Western Australia, and the Commissioner of Taxation for Western Australia. The dispute arose from the Commissioner's assessment of income tax on a commission earned by Watson from securing a remission of war-time profits tax for a client. Watson contended that this commission was income earned outside of Western Australia and therefore not subject to State income tax, while the Commissioner argued it was income derived from his profession carried on within the State. The matter was heard by the High Court of Australia on appeal from the Supreme Court of Western Australia.

The legal issues before the court were whether the commission received by Watson constituted income arising or accruing from his vocation as an accountant carried on in Western Australia, within the meaning of section 15(1) of the Land and Income Tax Assessment Act 1907-1924 (W.A.), and whether it was income earned outside of Western Australia, as contemplated by section 30(3) of the same Act. Specifically, the court had to determine the geographical source of the income and the relevant activities that generated it for the purposes of State income tax.

The court reasoned that Watson's commission arose from his vocation as an accountant carried on in Western Australia. Although he travelled to Melbourne to advocate for legislative amendments that would enable the tax remission, his initial arrangement with the client, the investigation of the client's tax affairs, and the ultimate securing and receipt of the remission all occurred in or were intrinsically linked to his business operations in Western Australia. The court found that the word "earned" in section 30(3) referred to the place where the earnings directly gave rise to income, rather than remote causes. The activities performed in Western Australia, namely obtaining the remission from the Commissioner and the initial arrangement for commission, were considered the effective cause of the income.

The High Court dismissed the appeal, affirming the decision of the Supreme Court of Western Australia. Consequently, the commission was held to be taxable income in Western Australia.
