GST for sole traders in Australia
You must register for GST once your business turnover reaches $75,000. Below that, it is your choice.
Last updated: November 2026
The rule
You need to register for GST if your GST turnover is $75,000 or more (non-profit organisations: $150,000). GST turnover is your business income, not profit. You must register within 21 days of realising you will go over.
Taxi and ride-sharing
Drivers of taxis, limousines and ride-sourcing services must register regardless of turnover.
Voluntary registration
Below the threshold you can still register. Then you must include GST in most prices, can claim GST credits on most business purchases, and must lodge activity statements.
What changes in OzHub
Add your ABN, switch GST on, and your invoices show the tax invoice details with GST at 10%. If you are not registered, leave GST off. See the invoicing app.
