Commissioner of Taxation v Word Investment Limited

The Commissioner of Taxation (the Commissioner) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the deductibility of interest expenses incurred by Word Investment Limited (Word Investment) on loans used to acquire shares in a company that was not a subsidiary. The dispute centred on whether these interest expenses were incurred in gaining or producing assessable income, or were otherwise necessarily incurred in carrying on a business for the purpose of gaining or producing assessable income, within the meaning of s 8-1 of the *Income Tax Assessment Act 1997* (Cth).

The High Court was required to determine whether the Full Federal Court had erred in finding that the interest expenses were deductible. Specifically, the court had to consider the application of s 8-1 to a situation where a company incurred debt to acquire shares in another entity, and whether the purpose of the acquisition, and consequently the incurring of the debt, was sufficiently connected to the taxpayer's business operations or the gaining of assessable income. The Commissioner argued that the acquisition of shares in a non-subsidiary was an investment, not part of the taxpayer's business, and therefore the interest was not deductible.

The High Court, in allowing the Commissioner's appeal, reasoned that the Full Federal Court had misapplied the principles established in *FCT v Coolgardie Gold Mining Co Ltd* and *Magna Developments Pty Ltd v FCT*. Their Honours held that the characterisation of the expenditure, and thus the deductibility of the interest, depended on the purpose for which the shares were acquired. In this instance, Word Investment acquired the shares as a passive investment, not as part of its business operations. Consequently, the interest expenses were not incurred in gaining or producing assessable income, nor were they necessarily incurred in carrying on a business for that purpose. The court emphasised that the mere fact that an investment might produce assessable income does not make the expenditure incurred in acquiring it deductible under s 8-1 if the acquisition itself is not part of the taxpayer's business.

The High Court ordered that the appeal be allowed, setting aside the decision of the Full Federal Court and remitting the matter to the Federal Court for determination of the quantum of tax payable.
