Terms of Use
By using gstcalculator.com.au you agree to these terms. They were last updated on 25 October 2026.
General information only
Everything on this site, including the calculator, guides and glossary, is general information. It is not tax, legal, accounting or financial advice, and it does not take your circumstances into account. Rules, rates, thresholds and due dates change. Confirm your position with the Australian Taxation Office or a registered tax professional before you rely on it.
No affiliation
This site is independent and is not affiliated with, or endorsed by, the ATO or any government body.
Accuracy of the calculator
The calculator uses the standard formulas for adding and removing GST and shows its workings. Results are estimates. You are responsible for deciding whether GST applies to a particular supply and for the figures you report to the ATO.
