Just wondering if someone could help here. I have a friend who is a tradesman and who registered for gst as a sole trader a few years ago as he was over the GST threshold. In this last year though he has had health issues so will not make the threshold. Is he still required to charge GSt because he is registered even though he will be way under the $75k this year? He is reluctant to deregister as the banks seem to require a gst registered abn before giving finance and he is also buying property as an investment. My understanding was that once youre registered you are obliged to charge gst even if you will be under the $75k threshold, is that correct? Most of his charges are for labour so although he can offset the materials he uses he would be better off had he never registered.
