Sars customs officers made more than 1,900 seizures of illegal imports worth R3.4bn, with counterfeit goods making up almost three-quarters of the total. Drugs (R432m), clothing and textiles (R286m) and cigarettes (R160m) made up the balance.
Customs also collected another R2.7bn for contraventions such as misclassification of goods, duty evasion, undervaluation of goods and infringements of rules of origin.
Cases involving international taxes and transfer pricing — a practice that allows for pricing transactions internally within businesses and between subsidiaries that operate under common control or ownership — raised R11.9bn.
Kieswetter said these cases were a focus of Sars' reinstated large business and international team and would become a focus of other teams.
The commissioner revealed that Sars was involved in 557 investigations of the illicit economy with an estimated value to the fiscus of R42.2bn.
Focus areas included fuel, tobacco, alcohol, clothing and textiles, leather and footwear, VAT carousels in the gold sector, phoenixism (liquidating a company only for the same business to re-emerge from the ashes as a fresh entity), abusive liquidation and business rescue practices and illicit financial flows.
More than 209 completed illicit economy investigations and debt cases had raised R11.9bn in income tax and VAT revenue.
