[MEDIA SUMMARY] Sasol Oil (Pty) Ltd v Commissioner for the South African Revenue Service

Sasol Oil (Pty) Ltd was part of the Sasol Group of companies. In 2001, contracts were entered into between companies within the Sasol Group for the supply of crude oil - a company in the Isle of Man supplied crude oil to a group company in London, which then on-sold the same crude oil to Sasol Oil in South Africa. The Commissioner for the South African Revenue Service (CSARS) issued additional assessments for the 2005, 2006 and 2007 tax years, asserting that these contracts were simulated transactions designed to avoid tax. The Tax Court (Johannesburg) upheld the Commissioner's position, finding the transactions were simulated and should be disregarded. Sasol Oil appealed to the Supreme Court of Appeal. The evidence showed that the contracts were first concluded in 2001, before residence-based tax was introduced in mid-2001. Liability for residence-based tax would only have arisen in 2004 when the Isle of Man company became a foreign controlled company in relation to Sasol Oil.

• Whether the contracts for the supply of crude oil between Sasol Group companies were simulated transactions
• Whether the Commissioner was entitled to disregard the transactions and issue additional assessments for the 2005, 2006 and 2007 tax years
• Whether the transactions were entered into with the intention to avoid tax
• Whether the transactions had genuine commercial justification

The appeal was upheld. The Supreme Court of Appeal found that the Commissioner was not entitled to issue the additional assessments for the 2005, 2006 and 2007 tax years. Sasol Oil's appeal to the Tax Court against the assessments should have been upheld. The Tax Court's decision was overturned.

For transactions to be disregarded as simulated for tax purposes, there must be evidence that they were entered into with the intention to create a false impression rather than for genuine commercial reasons. The timing of when contracts were concluded relative to when tax legislation was introduced is a critical factor in determining intention. Where uncontroverted evidence establishes that contracts had commercial justification when concluded, and where the alleged tax liability would only arise years later due to changed circumstances, simulation cannot be established. A finding of simulation involving multiple parties, corporate entities and professional advisors over an extended period requires substantial evidence of fraudulent intent, which cannot be inferred merely from the existence of tax benefits.

The court observed that a finding of simulation in this case would have required finding that many individuals, corporate entities and several firms of auditors were party to fraud over a lengthy period. The court noted there was no evidence at all to support such a serious finding. This suggests that courts should be cautious about making findings of simulation that implicate the integrity of multiple parties and professional advisors without clear evidence of collusion or fraudulent conduct.

This case is significant in South African tax law as it clarifies the test for simulation in tax avoidance cases. It establishes that the Commissioner cannot disregard transactions as simulated merely because they may result in tax benefits. The case emphasizes that courts must consider the timing of transactions, the commercial rationale at the time contracts were concluded, and require substantial evidence before finding simulation. It reinforces that simulation requires proof of dishonest intent, not merely tax efficiency. The judgment protects legitimate commercial structuring within corporate groups and places a high evidentiary burden on SARS when alleging simulation involving multiple parties over extended periods. It demonstrates the importance of examining contemporaneous evidence and commercial justification when assessing whether transactions are genuine.
