Hyder v Commissioner of Taxation

Hyder v Commissioner of Taxation involved an appeal by the Appellants against decisions of the primary judge concerning the legality of the Commissioner of Taxation's actions in issuing assessments and determining the accrual of interest. The Appellants argued that the Commissioner's conduct in issuing assessments to multiple taxpayers for the same income source was unlawful and that general interest charge (GIC) should not accrue on the assessments without crediting the tax already paid by another taxpayer. The Court was required to determine the validity of the Commissioner’s conduct in issuing the assessments, the legality of enforcing payment on these assessments, and whether GIC should accrue without considering the tax already paid by a different taxpayer.

The Court examined the principle established in Richardson v Federal Commissioner of Taxation, which emphasises that income should not be taxed more than once for the same period. However, the Court found that the principle did not apply rigidly in all circumstances and that the Commissioner was entitled to issue alternative assessments to different taxpayers for the same income. The Court also held that the Commissioner's conduct from 28 May 2021 to 27 July 2021 was oppressive and unlawful, as it sought to enforce payment from both the Appellant and the Trustee despite issuing alternative assessments. Nevertheless, the Court found no basis for granting an injunction or writ of prohibition since the Commissioner had undertaken not to commence recovery proceedings.

The Court further ruled that the decision to refuse to defer the due date for payment of the assessments was flawed for failing to consider relevant factors. The matter was remitted for reconsideration. The Court dismissed the appeal, holding that the Commissioner’s conduct in issuing the assessments was lawful, and that the Appellants' arguments regarding the accrual of GIC were not well-founded under the circumstances presented. The Appellants were ordered to pay the Respondent's costs of the appeal.
