RAC Insurance Pty Ltd v Commissioner of Taxation

RAC Insurance Pty Ltd (RAC) sought special leave to appeal from a decision of the Full Court of the High Court of Australia concerning the tax treatment of profits derived from the realisation of certain investments. The dispute centred on whether these profits were assessable as income for the years 1984, 1985, and 1986. The trial judge had previously resolved issues relating to the 1983 tax year on a separate point, which was no longer in contention.

The legal issues before the High Court involved determining whether profits from the sale of government bonds, semi-government securities, shares, and debentures were to be included in RAC's assessable income. Specifically, the court had to consider whether these investments were part of RAC's insurance business, and if the principle applied to life insurance companies, which ordinarily brings profits from investment realisation into account, extended to general insurers like RAC.

RAC argued that the inclusion of these investments in the calculation of its solvency margin under the *Insurance Act 1973* did not necessitate their characterisation as part of its insurance business for income tax purposes. It contended that even if these specific investments were excluded, RAC would still have met its solvency margin requirements. RAC submitted that the lower courts had erred by wrongly extending the principles applicable to life insurers to general insurers, asserting that there was no finding or concession below that RAC conducted a separate investment business or that the investments were integral to its insurance operations. The Full Court had briefly addressed the matter, stating that profits derived from the sale of investments are ordinarily brought to account in the assessment of income for banking or insurance companies.
