TBLX and ZSCM and Commissioner of Taxation (Taxation)

This matter concerned appeals by TBLX and ZSCM (referred to collectively as "the applicants") against decisions of the Commissioner of Taxation. The dispute centred on whether the Administrative Appeals Tribunal (AAT) had jurisdiction to review "nil assessments" and the proper characterisation of certain deposits as income rather than loans. The applicants sought to challenge amended notices of assessment issued by the Commissioner for the 2017 income year.

The primary legal issues before the court were whether the Tribunal possessed jurisdiction under Part IVC of the *Taxation Administration Act 1953* (Cth) to review a "nil assessment," and whether certain deposits totalling $643,600 were properly characterised as income of the Trust or as loans. Additionally, the court considered the onus of proof resting on the applicants to demonstrate that the Commissioner's assessments were excessive, particularly in circumstances where corroborating independent material was scarce, with the applicants attributing the destruction of such material to a fire. The reviewability of PAYG tax credits and the remission of penalty assessments were also pertinent questions.

The court affirmed the decision in relation to TBLX, finding that the Tribunal did have jurisdiction to review the Commissioner's decisions. The reasoning emphasised that the applicants bore the onus of proving their case, and in the absence of sufficient contemporaneous or independently verifiable material, their claims regarding the characterisation of deposits as loans were not established to the court's reasonable satisfaction. The court noted the difficulties in proving oral agreements and the lack of reliable corroboration, referencing established principles regarding the burden of proof and the need for actual persuasion of the court. The court dismissed the application by ZSCM.
