Obeid and Commissioner of Taxation (Taxation)

This matter concerned an application by members of a family, who were beneficiaries of a trust, to the Administrative Appeals Tribunal (AAT). The Commissioner of Taxation had issued amended assessments for the years 2003-2013, alleging fraud or evasion due to understated income and overstated expenses in businesses controlled by the trust. The applicants objected to these amended assessments and the imposed administrative penalties, and were required to satisfy the onus under s 14ZZK(b) of the *Taxation Administration Act 1953* (Cth) to prove the Commissioner's assessments were wrong and to establish the correct assessments.

The primary legal issues before the Tribunal were to determine the correct taxable income of the applicants, considering the Commissioner's amended assessments which arose from an audit suggesting under-reporting of business takings and over-estimation of wage costs. Additionally, the Tribunal was required to consider whether the Commissioner had properly formed an opinion as to fraud or evasion, and whether the 75% administrative penalties were appropriate or should be remitted. A further issue involved the scope of the Commissioner's obligation to produce documents under s 37 of the *Administrative Appeals Tribunal Act 1975* (Cth), as modified by s 14ZZF of the *Taxation Administration Act 1953* (Cth).

The Tribunal reasoned that the onus of proof rests on taxpayers because they are generally in the best position to explain their financial affairs, and the Commissioner is not obligated to prove the correctness of his assessments. The court noted that s 14ZZF of the *Taxation Administration Act 1953* (Cth) narrows the Commissioner's obligation to produce documents under s 37 of the *Administrative Appeals Tribunal Act 1975* (Cth) to those he regards as necessary for the review, rather than all relevant documents. Documents must be identified with sufficient precision, and the taxpayer must establish a potential connection between the documents sought and the facts in issue. The Tribunal also considered statements filed by Mr Di Girolamo and Mr Sassine.
