With regards to SARS payments initiated through eFiling, I have given up on Standard bank. Tired to escalate the matter via Standard Bank and SAIT, but no person in S/B seem to know how the link must be acitvated. All other have a very easy process, load payment on eFiling and client log-on and approve. Standard bank clients just can not get it to work. Thus, they make the payment themselves and I provide them with the reference number. I have not had any client coming back to say the reference number is too long. What is important that they select the correct SARS account. As for reference number changing, have not noticed that. Amount owing changes with interest added every time a statement is requested.
