Can I adjust my ITR12 once it has been submitted?

I have submitted and received a refund for filing my ITR12 (due by end of Nov 2016). I have been made aware that I could have claimed back on a loss on a property (rental not covering the bond) and wondered if there was a way I could adjust and resubmit this form?

Yes you can resubmit your tax return, kindly log into your TaxTim profile and select a 2016 annual tax return and we'll help you declare rental loss.
Kindly read our blog on what else you can claim:
