I DO NOT HAVE A FIXED SALARY AS I AM SELF EMPLOYED. WHAT DO I DO NOW?

If you earn other income besides a salary you will have to complete an IRP6 form if you estimate that your income for the year will be greater than R63 556. You would also need to register as a provisional taxpayer and submit a return twice a year called the IRP6 as well as the ITR12 year end return.
