Taxpayers owe Sars R82 billion for the last financial year.
If that money were to materialise, it would nearly halve the country’s budget deficit, of R168bn.
Sars says it’s working hard to modernise and improve its systems and make it easier and quicker to pay taxes.
But the revenue service says many taxpayers simply refuse to pay up, arguing that the money is wasted by corupt government officials.
In a bid to win taxpayers over, Sars is focusing on an education campaign.
Sars Commissioner Oupa Magashule says, "What will begin to happen over the next few years is, using the foundation created by our modernised environment, we will increasingly be able to realise our vision for a more active and engaged citizenry as part of the social compact between citizens and the state. This is the true essence of our compliance model in which citizens voluntarily meet their obligations in an engaged, active and meaningful way. To do this means they each need to have a relationship and interaction with SARS. This means encouraging tax and customs compliance from the start: through education, through engagement and through registration even before they may be liable for tax.”
