I'm repairing appliances and my own vehicles. Do I have to do 2 tax returns?I also recently repaired another vehicle. Do I have to show it in 2 tax returns-1 for appliances and 1 for vehicles?I have to repair my own vehicles because I cannot afford to pay for repairs to be done.

Are you running a business (i.e earning income) from repairing appliances?
And if yes, is this through a registered company (pty)?

Yes -but not a registered company-in my personal capacity T/A.

You would only need to complete one tax return (ITR12) - you would declare the income and expenses from your business within the local business section.
