A small business with a turnover of less than $75,000 per annum does not need to be registered for GST. As a small business owner you need to monitor your turnover so you know when you are likely to go over this threshold.
Your Xero Bookkeeper can set you up with a Xero Cashbook for as little as $10 per month. This will allow you to easily monitor your income and see if you are nearing the $75,000 threshold. Then, if necessary register your business for GST.
