Kieswetter said voluntary compliance was the highest leverage to reduce the tax burden on everyone.
He encouraged taxpayers to use online channels such as eFiling and Sars’s mobile app.
The closing date for the tax season will be October 31 for those filing at Sars branches. For taxpayers who use eFiling, the deadline is December 4 and for provisional taxpayers who file online the closing date is January 31, 2020.
Kieswetter said tax was simply an overlay of economic activity and if Sars was better connected to the economy it could serve it better.
The commissioner gave a warning to those who were not tax compliant and said there would be consequences.
“We go out of our way to assist honest taxpayers but dishonest taxpayers will experience consequences of their action.”
Kieswetter was giving an update on the upcoming tax season, a month after he took office as commissioner.
President Cyril Ramaphosa announced his appointment in March.
Kieswetter took over from Mark Kingon, a Sars veteran who took over in an acting capacity after Ramaphosa suspended Tom Moyane in 2018.
The former commissioner was fired in November, in line with recommendations from judge Robert Nugent, who headed a commission of inquiry into governance failures at the institution. The failures were blamed for revenue shortfalls that led to a VAT increase in 2018, the first in more than two decades, which hurt the country’s poorest.
