Goldsworthy Mining Ltd v Commissioner of Taxation

Goldsworthy Mining Ltd (the taxpayer) appealed to the High Court of Australia against a decision of the Federal Court of Australia, which had affirmed a determination by the Commissioner of Taxation (the Commissioner) that the taxpayer was liable for additional tax under section 245 of the *Income Tax Assessment Act 1936* (Cth) (the Act). The dispute concerned the Commissioner's assessment of the taxpayer's liability for additional tax arising from an understatement of assessable income in its 1967 income year return.

The primary legal issue before the High Court was whether the taxpayer had established a reasonable excuse for its failure to furnish a return within the time prescribed by the Act, thereby avoiding the imposition of additional tax under section 245. This required the court to consider the nature of "reasonable excuse" in the context of tax legislation and the taxpayer's conduct in relation to its tax obligations.

The court, comprising Barwick C.J., Gibbs and Stephen JJ. (Menzies J. having died before judgment), reasoned that the taxpayer's reliance on its accountants to prepare and lodge its tax return did not, in itself, constitute a reasonable excuse for the late lodgement. The taxpayer had a direct responsibility to ensure its tax obligations were met, and the failure of its agents to do so did not absolve the taxpayer of its duty. The court applied the principle that a taxpayer cannot delegate its statutory obligations in a way that excuses it from compliance, particularly when the failure stems from the negligence or oversight of its chosen representatives. The court found that the taxpayer had not demonstrated that it had taken all reasonable steps to ensure compliance with its tax obligations.

The appeal was dismissed, and the taxpayer was liable for the additional tax as determined by the Commissioner.
