The seventh is not a suggestion
EMP201 is due by the seventh of the month following the payroll it covers. Not the seventh working day, not the Friday nearest the seventh. If the seventh falls on a weekend or a public holiday it moves earlier, not later — which catches out more employers than any other rule in the calendar.
The penalty for paying late is ten percent of the amount due, and it applies from day one. There is no grace period and no sliding scale. An employer with a R180,000 monthly PAYE, UIF and SDL liability who files three days late has spent R18,000 on nothing at all.
What makes this avoidable is that the number is knowable a week in advance. The payroll is run before month end; the liability is fixed the moment the last payslip is finalised. Any practice that hands you the figure on the sixth is doing it wrong — you should have it before the month has closed.
