BP Southern Africa (Pty) Ltd (BPSA), a petroleum refiner and marketer in South Africa, is a subsidiary of BP Plc. Since about 1959 BPSA had used BP-owned trademarks and marketing indicia, initially under informal and later written arrangements without paying royalties. In 1997, following a valuation of BP’s intellectual property, BPSA entered into a written trademark licence agreement with BP under which it paid annual royalties calculated per litre of product sold. For the 1997–1999 tax years BPSA paid substantial royalties and claimed them as deductions under section 11(a) of the Income Tax Act 58 of 1962. SARS disallowed the deductions on the basis that the expenditure was capital in nature. BPSA’s objection and appeal to the Income Tax Special Court failed, and it appealed to the Supreme Court of Appeal.
