Questions are being raised about whether the Gupta brothers have been dishonest in their tax declarations.
This follows reports that they told the South African Revenue Service (Sars) that between 2011 and 2013, they each earned R1 million a year.
Scorpio and amaBhungane reveal the latest from the Gupta leaks in a report on Wednesday.
Two months ago, thousands of leaked emails exposed politicians and state-owned entity executives, linking them to the controversial Gupta family.
With properties in Dubai, a private jet and a lavish wedding with guests ushered into the country on a private charter, the family has become synonymous with living large.
But how much do they earn?
The Gupta leaks show that between 2011 and 2013, Sars accepted declarations from three Gupta brothers, stating that they earned personal income of R1 million or less a year.
The brothers then paid tax on those amounts.
For example, in 2013, Atul Gupta told Sars that he earned just over R1 million that year and paid R376,000 tax.
Sars declined to comment and did not respond to Scorpio’s question on whether the Guptas have been subjected to a tax audit.
