Hi Miriam. Every month you need to fill in a form UI-19 for all employees as well as an EMP201 and make payment to SARS within seven days after the end of the month.

This can also be done electronically.

In terms of Section 8 of the UIC Act, UIF contributions deducted must be paid over to SARS within seven (7) days after the end of the month in respect of which the contributions are payable.
In terms of Section 8(2) of the UIC Act, the employer must submit a statement in such form as the Commissioner may prescribe when making any payment. The prescribed statement (EMP201) is automatically supplied to registered employers for payment purposes each month.
