Quick GST Guide for Tradies

Goods and Services Tax (GST) is a 10% tax on most goods and services sold in Australia. As a tradie, you charge GST on your services and can claim GST credits on your business purchases.

You must register for GST if your annual turnover is $75,000 or more. You can also register voluntarily if your turnover is less than this amount.

Most small tradies lodge quarterly Business Activity Statements (BAS). Quarter end dates are: Sep 30, Dec 31, Mar 31, Jun 30. Lodging is usually due 28 days after quarter end.

You can claim GST credits on most business purchases including: tools, equipment, vehicle expenses (business portion), materials, insurance, phone/internet, and other business expenses.
