Frequently Asked Questions
How do I calculate GST on a price in Australia?
To add GST: multiply the price by 1.1 (e.g., $100 x 1.1 = $110 including GST). To find the GST amount in a GST-inclusive price: divide by 11 (e.g., $110 / 11 = $10 GST).
What is the GST rate in Australia?
The Australian GST rate is a flat 10% on most goods and services. It has been 10% since its introduction on 1 July 2000. Some items are GST-free, including basic food, medical services, and education.
What items are GST-free in Australia?
GST-free items include basic food (fresh fruit, vegetables, meat, bread, milk), most health services, education courses, childcare, and exports. Processed foods, takeaway meals and restaurant dining do include GST.
Do I need to register for GST?
You must register for GST if your business has a GST turnover of $75,000 or more per year ($150,000 for non-profit organisations). Below this threshold, registration is voluntary but can be beneficial for claiming input tax credits.
How do I report GST on my BAS?
Report GST collected on sales (1A) and GST paid on purchases (1B) on your Business Activity Statement. The difference is what you owe the ATO or are refunded. BAS is lodged monthly or quarterly depending on your turnover.
