Tax revenue windfall offers relief, but risks remain

Finance Minister Enoch Godongwana can approach Wednesday's medium-term budget policy statement with relief, as tax collections are estimated to exceed expectations by between R40 billion and R70 billion. The stronger-than-expected revenue is due to heightened resilience in the economy, driven by elevated precious metal prices that have increased mining profits, as well as improved efficiency in broadening the tax base.

However, the windfall from the mining sector is cyclical and may not last. Sars is collecting about R100 billion per year, but it is becoming increasingly difficult to collect additional R30 billion. Tax specialists have expressed concerns about harsher understatement penalties imposed by Sars, less willingness to settle, and more cases being heard at the Tax Court.

The proposed amendment to the Tax Administration Laws Amendment Bill could further boost Sars's revenue through penalties imposed on the existing tax base. However, changing consequences after the fact undermines legal certainty and the rule of law. Debt collection efforts by Sars show undisputed tax debt at R557.5 billion and disputed debt R134.2 billion, totaling approximately R692 billion.

However, the increasing number of tax disputes suggests that taxpayers are pushing back against Sars. Illicit trade and economic activity are also a concern, with illicit cigarettes now making up almost 75% of the market, resulting in an estimated R30 billion in lost tax revenue.
