Incorrect Information on SARS System

Hi, my date of Birth, nature of person, Cell No & country of origin on my IRP5 is incorrect. I only noticed it last year when I was standing in the queue at SARS. I submitted with no problem, this year my Company corrected my details. I tried to register for efiling, but they state that the information they have on their system does not match with what I have entered when registering. Please help, what should I do? Should the company do anything from their side to correct the information that SARS has for me, or can I go in and change the info at my local SARS branch? Can I register with efiling using the info that SARS already have on their system from last year? AND most importantly when I Submit with my CORRECT info, will I have any problems because of the information that changed?

You need to go into SARS with all your current and correct details, they will update the system and then you can submit as normal.
