Lambourne and Commissioner of Taxation (Taxation)

This matter concerned an application for review of a decision by the Commissioner of Taxation concerning the deductibility of work-related expenses and the imposition of an administrative penalty. The applicant, employed by the Australian Defence Force as an Electronics Technician, claimed deductions for work-related clothing and other work-related expenses in his 2017 income tax return. Following an audit, the Commissioner amended the assessment, disallowing a significant portion of these claimed deductions and imposing a shortfall penalty for failure to take reasonable care.

The primary legal issues before the Tribunal were whether the applicant had discharged his onus to prove that the disallowed deductions for work-related clothing and other work-related expenses were incurred in gaining or producing his assessable income for the 2017 year, and whether the administrative penalty imposed by the Commissioner was correctly imposed and should be remitted. The Tribunal was required to consider the requirements of section 8-1 of the *Income Tax Assessment Act 1997* (ITAA 1997) regarding the deductibility of losses and outgoings, and the substantiation requirements under Division 900 of the ITAA 1997.

The Tribunal found that the applicant had failed to discharge his onus to prove that the disputed amounts were incurred in gaining or producing his assessable income. Specifically, regarding the work-related clothing claim, the applicant could not provide sufficient details of individual invoice amounts, the specific items purchased, or their relevant costs to substantiate the claim. Similarly, for other work-related expenses, the applicant did not provide adequate evidence. The Tribunal noted that while the applicant may have purchased items consistent with his role, the onus remained on him to prove entitlement to the deductions and to substantiate them in accordance with the law.

Consequently, the Tribunal affirmed the Commissioner's decision, finding that the amended assessment was not excessive or incorrect. The Tribunal also found that the administrative penalty was correctly imposed, as the applicant had not produced sufficient evidence to warrant the exercise of discretion to remit the penalty under section 298-20 of Schedule 1 to the *Taxation Administration Act 1953*.
