A Limpopo businessman who made donations to the ANC Youth League has been accused of not complying with tax legislation, the Sunday Independent reported.
Johan Beukes, 44, owns a Polokwane-based construction firm, Mahlehle, which allegedly benefited from government housing contracts.
The newspaper reported that Beukes was being questioned about his donations to the youth league.
His donations were revealed in a judicial inquiry at the Pretoria High Court on Tuesday and Wednesday.
Malema told the newspaper on Saturday that the SA Revenue Service was trying to sensationalise the matter.
"I know [Beukes] as a businessman in Limpopo. He is one of many people who used to donate to the ANCYL. They even helped towards a house built by the Ratanang Trust by providing labour," he was quoted as saying.
Beukes declared a gross income of R655, 317 for 2010, but in fact earned R1.4 million for that year, according to the weekly, which cited court papers.
SARS has accused Beukes of not complying with the Income Tax Act and the Value Added Tax Act.
It also contends that some of his payments may have contravened the Prevention of Organised Crime Act.
Court papers revealed that there were links between Beukes and expelled youth leader.
Beukes' attorney, Rian van der Walt, confirmed the donations but said donations had also been made to the Democratic Alliance and to the Congress of the People, who were not under scrutiny,
Sars told the newspaper it could not discuss taxpayers' affairs.
