Common questions
How do I calculate GST in Australia?
To add GST, multiply the price by 0.10 and add it on (or multiply by 1.10 for the total). To remove GST from a GST-inclusive amount, divide by 11 to get the GST portion, or divide the total by 1.10 to get the price before GST.
What is the GST rate in Australia?
GST is a flat 10% on most goods and services. Some items are GST-free, including most basic food, some health and education services, and exports.
When do I have to register for GST?
You must register once your business turnover reaches $75,000 a year (or $150,000 for non-profits), or straight away if you drive taxis or rideshare. Below that you can register voluntarily to claim GST credits.
What is a BAS?
A Business Activity Statement is how registered businesses report and pay GST to the ATO, usually quarterly. You report the GST you collected on sales, minus the GST credits on your purchases, and pay or receive the difference.
