Mustapha and Commissioner of Taxation (Taxation)

This matter concerned an application for review of an objection decision by Mr Mustapha, the applicant, concerning amended income tax assessments for the years ended 30 June 2017 and 30 June 2018. The applicant had lodged his tax returns declaring taxable incomes of $171,816 and $171,049 respectively. However, following a taxation audit, the Commissioner of Taxation issued default assessments of $227,556 for the 2017 year and $593,857 for the 2018 year, reflecting ATM withdrawals from a company account of which the applicant was the sole director, shareholder, and cardholder. The Commissioner also imposed shortfall penalties for intentional disregard of taxation law. The applicant's objection was limited to disputing that he made the ATM withdrawals and asserting that a specific deposit was transferred to a personal account. The Administrative Appeals Tribunal considered the applicant's objection decision.

The primary legal issues before the Tribunal were whether the amended assessments issued by the Commissioner were excessive or unreasonable, and whether the applicant had discharged his onus of proving his actual taxable income. Specifically, the Tribunal had to determine if the applicant had provided sufficient probative evidence to substantiate his claims regarding the ATM withdrawals from the company account and to demonstrate that these withdrawals did not form part of his taxable income. The Tribunal also considered the applicant's failure to object to the penalties and shortfall interest charges.

The Tribunal found that the applicant had failed to discharge his onus of proof. The applicant's evidence regarding the ATM withdrawals was considered minimal, inexact, vague, and unreliable. He did not adduce evidence of his actual income, which was identified as a significant deficiency. The Tribunal noted that the applicant could have called relevant witnesses, such as Mr Karelis and Mr Matar, and produced company records, but failed to do so. Consequently, the Tribunal was not satisfied that the applicant had provided probative evidence to show that the ATM withdrawals from the company account were not part of his taxable income. The Tribunal affirmed the objection decision.
