Ord Forrest Pty Ltd v Federal Commissioner of Taxation

Ord Forrest Pty 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 226 of the *Income Tax Assessment Act 1936* (Cth) (the Act). The dispute concerned the taxpayer's failure to furnish a return for the year ended 30 June 1971, and the Commissioner's subsequent assessment of additional tax.

The High Court was required to determine whether the taxpayer had a reasonable excuse for failing to furnish its income tax return by the due date. Specifically, the court had to consider whether the taxpayer's belief that it was not liable to furnish a return, based on its understanding of its tax position, constituted a reasonable excuse within the meaning of section 226(2) of the Act.

The court held that a taxpayer's belief that it is not liable to furnish a return, even if honestly held, does not constitute a reasonable excuse for failing to do so if that belief is based on a misunderstanding of the law or a misapplication of the facts to the law. The court reasoned that the obligation to furnish a return is a statutory duty, and a taxpayer cannot rely on their own erroneous view of their legal obligations as an excuse for non-compliance. The onus is on the taxpayer to ensure they understand their obligations and to seek professional advice if necessary.

The appeal was dismissed, and the Commissioner's assessment of additional tax was upheld.
