The annual report and audited financial statements for 2015/16 of the South African National Roads Agency (Sanral) were tabled in Parliament on Wednesday.
The financial results show that Sanral's toll road operations have seen a decline in revenue of 20% and the revenue from the Gauteng highways decreased by R1.7 billion.
Wayne Duvenage, Chairman of The Organisation Undoing Tax Abuse (OUTA) says this could be proof that the tolling project is failing and they are not getting a much revenue as they did in the first year.
He says they are writing off a lot of etolls bills.
According to Duvenage, the financials show that they have collected R2 billion in revenue on etolls but says the reality is they've only managed to collect R819 million.
We have a whole lot of question marks on their accounting practices which goes against their policies.— Wayne Duvenage, Chairman of The Organisation Undoing Tax Abuse (OUTA)
Duvenage says they will be taking up these concerns with Sanral soon.
A discount period will be initiated to allow people to pay back what Sanral says they owe but Duvenage says this method did not work in the past and it will certainly not work in future.
He says only 1 in 5 people are paying their toll bills.
