Taxpayers should ensure that their tax number and personal details remain updated with SARS.
HOW THE INCOME TAX PROCESS WORKS
The annual tax process generally follows six stages:

Generally, supporting records should be retained for at least five years.
Step 3 – Tax Return Submission
Each year taxpayers may be required to submit an Income Tax Return (ITR12). The return declares:
- Income received
- Deductions claimed
- Tax credits applicable
Returns are submitted through SARS eFiling or the SARS MobiApp.
Step 4 – SARS Verification
SARS may request supporting documentation to verify information declared on the tax return. Common requests include:

- Banking records
Step 5 – SARS Assessment
