SABC employees were not paid their salaries on Tuesday, staffers reported.
The broadcaster had warned that it might reach Day Zero this year, as a result of its financial problems.
"Day Zero at the SABC has arrived sooner than we thought. We haven't been paid," one staffer told TMTV.
The SABC reported a loss of R622 million for the year ended 31 March 2018, according to reports.
SABC board member Mathatha Tsedu warned parliament about the impending financial doom in November.
*UPDATE: The SABC later released a statement in which it blamed the non-payment on a banking glitch and said salaries would be paid by the end of the day.
