I went to a SARS office and I didn't have my IRP5 with me, but they asked me for my I.D. They checked for me on the system and they gave me my Tax number. I received 2 smses on my cellphone thanking me for filling my 2012 and 2013 tax return and they also stated the amount due to me. The lady that helped me said I should wait for a mail that will be sent to me via post by SARS and then I should come back to confirm my account details. So I just want to know if I should bring my IRP5 next time when I go back to SARS or don't I need it anymore?
