AECI Ltd had for decades owned extensive land at Modderfontein as a capital asset. As the land became surplus to its operational needs, AECI formed a wholly owned subsidiary, Founders Hill (Pty) Ltd, expressly described as a ‘realization company’, to which it sold portions of the land. Founders Hill acquired the land with the stated purpose of realising it to best advantage and thereafter winding up. The land was subdivided, developed (including rezoning, servicing, and marketing), and sold over a number of years, with professional developers and marketing agents engaged. The Commissioner initially treated the proceeds as capital but later issued revised assessments for the 2000 and 2001 tax years, contending that the profits were taxable income as Founders Hill was trading in land. The Tax Court held the proceeds to be capital in nature. The Commissioner appealed to the Supreme Court of Appeal.
