Give the Client correct,simple and factual information before they need to apply for an ABN and not state that it is FREE IF done through "AIRTAX" Getting an ABN is free through the ATO when completed through the ABR (Australian Business Register). Tell them what they should be aware of when they exceed the monetary value of 75K at that GST will then need to be applied and explain to them why. I eventually phoned the ATO out of shear frustration and had all my questions answered in plain English,and easily understood No need to bombard individuals with links and too much information, if they ask a question, and you can answer it-answer it in plain English....Simple!. Thank you
