GST and Business Tax Australia — Complete Guide for Sole Traders and Small Business

Updated

Goods and Services Tax (GST) is a 10% tax on most goods and services sold in Australia. If your business has a turnover of $75,000 or more per year — or $150,000 if you are a non-profit — you must register for GST and start collecting it from customers. For freelancers, sole traders, and small business owners, understanding your GST obligations, ABN requirements, and Business Activity Statement (BAS) lodgement is fundamental to staying compliant with the ATO.

This cluster covers GST basics, BAS lodgement, the tax obligations of sole traders and self-employed people, Fringe Benefits Tax (FBT), and the state-based payroll tax system.
