Do I need to register for GST?
This is the question we field most often from newer Hills District operators, and the answer comes down to turnover. You are required to register for GST once your business turnover hits $75,000 or more across any rolling 12-month period — or as soon as you reasonably expect to reach it. Because the test is rolling rather than tied to the financial year, a strong few months of work in Castle Hill, Norwest or Baulkham Hills can push you over before the books show it, so it pays to watch the running total rather than waiting for 30 June.
A handful of activities, such as taxi and rideshare driving, must register from the very first dollar regardless of turnover. Below the threshold, registration is optional. Some businesses choose to register voluntarily — for instance, when most customers are themselves GST-registered and can claim the credit, or when claiming input tax credits on early start-up costs is worthwhile. Once you are registered you add GST to your taxable sales, claim credits on your business purchases, and report the net position on your BAS.
- Compulsory at $75,000 turnover over a rolling 12-month period
- Some activities (taxi, rideshare) must register from the first dollar
- Voluntary registration can suit B2B businesses or heavy start-up costs
- Registration brings ongoing BAS reporting, so weigh it deliberately
