An Income Tax Return (ITR12) is a form that SARS requires all individuals (including provisional taxpayers) to complete and submit to SARS once every year.
The form is used to declare your income, deductions and tax credits to SARS, so that SARS can calculate how much tax you need to pay, or the refund due to you.
Taxpayers, including provisional taxpayers, only need to complete and submit an ITR12 (income tax return) once a year. The ITR12 form allows you to capture all your income, with separate sections for different types of income. For example, if you worked two jobs, you would receive two IRP5S (one from each employer). You would simply declare both IRP5 tax certificates on your tax return, one after the other - it is very important to never combine information unless it is required.
