Below is a list of possible documents needed when completing your tax return. Your tax return is also known as a ITR12 on Efiling.
You will use the documents mentioned above, as well as any other applicable documentations, when completing your tax return on Efiling. You will only need to provide this to SARS in the event of them selecting you for verification.
Verification is a process where SARS validates your tax return input to the relevant, appropriate supporting documentation.
It is important to also note that you must keep all your supporting documents safely for a period of FIVE years from the date of submission, should SARS require them in future.
