Miller v Dep Commissionr of Taxation

Miller (the applicant) sought judicial review of a decision by the Deputy Commissioner of Taxation (the respondent) to disallow an objection against an assessment of income tax. The dispute concerned the deductibility of certain expenses incurred by the applicant.

The primary legal issue before Callinan J was whether the expenses claimed by the applicant were properly deductible under the *Income Tax Assessment Act 1936* (Cth). Specifically, the court had to consider whether the expenses were incurred in gaining or producing assessable income, or were necessarily incurred in carrying on a business for the purpose of gaining or producing assessable income.

Callinan J found that the applicant had failed to establish that the expenses were deductible. His Honour reasoned that the applicant had not demonstrated a sufficient nexus between the expenditure and the gaining or production of assessable income. The onus was on the applicant to prove that the expenses met the statutory requirements for deductibility, and this onus had not been discharged. The application for judicial review was dismissed.
