Commissioner for the South African Revenue Service v NWK Limited

Between 1999 and 2003 NWK Ltd claimed income tax deductions under s 11(a) of the Income Tax Act 58 of 1962 for interest allegedly paid on a loan of R96 415 776 advanced by Slab Trading Company (Pty) Ltd, a subsidiary of FNB. The loan formed part of a complex suite of interlinked transactions involving forward sales of maize, cessions of rights, and discounted promissory notes. Although the documentation reflected a loan of approximately R96 million repayable by delivery of maize, the Commissioner contended that in substance only R50 million was ever advanced, and that the remaining amount represented capital dressed up as interest through simulated transactions designed to generate excessive interest deductions. In 2003 SARS issued additional assessments disallowing the deductions and imposed additional tax and interest. The Tax Court upheld NWK’s appeal, finding the transactions genuine. SARS appealed to the Supreme Court of Appeal.

The appeal by the Commissioner was upheld with costs. The Tax Court’s order was replaced with an order dismissing NWK’s objection to the additional assessments and upholding them, while reducing the additional tax imposed to 100% of the additional assessments in terms of s 76 of the Income Tax Act.

This is a leading South African authority on simulated transactions and tax avoidance. It clarified that the test for simulation focuses on the true commercial substance and legal effect intended by the parties, not merely on their professed intention to perform the contracts. The case significantly strengthened SARS’s ability to challenge complex tax-driven schemes and confirmed that the general anti-avoidance provision (s 103(1)) may apply even where simulation is not conclusively established.
