Frequently Asked Questions About Australian GST
What is GST in Australia and what is the current rate?
GST (Goods and Services Tax) is a broad-based tax of 10% on most goods, services, and other items sold or consumed in Australia. The Australian GST rate has been 10% since it was introduced on 1 July 2000. GST is included in the price of most goods and services you buy. Our GST calculator Australia uses the standard 10% rate to help you add, remove, or split GST from amounts accurately.
How do I add GST to a price in Australia?
To add GST to a price, multiply the base amount by 0.10 (10%). For example, if an item costs $100 excluding GST, the GST amount is $10, making the total price $110 including GST. Our GST calculator can add GST automatically - just enter the base amount and select "Add GST" to see the GST amount and total price including GST.
How do I remove GST from a price that includes GST?
To remove GST from a price that includes GST, divide the total amount by 11 and multiply by 10. For example, if an item costs $110 including GST, the GST amount is $10 ($110 ÷ 11), and the base amount is $100. Alternatively, divide by 1.1. Our GST calculator Australia handles this calculation automatically when you select "Remove GST" and enter the total amount.
What items are GST-free or exempt from GST in Australia?
Some items are GST-free in Australia, including: most basic foods (fresh fruit, vegetables, bread, milk), medical services and medicines, education courses, exports, and some financial services. Other items are input-taxed (no GST on sales, but can't claim GST credits), such as residential rent and some financial services. Most other goods and services are taxable at 10%. Our calculator assumes standard 10% GST - check with the ATO for GST-free items.
Do I need to register for GST in Australia?
You must register for GST if your business has a GST turnover of $75,000 or more per year (or $150,000 for non-profit organizations). You can also register voluntarily if your turnover is below these thresholds. Once registered, you must charge GST on taxable sales, claim GST credits on business purchases, and lodge Business Activity Statements (BAS). Our GST calculator helps you calculate GST amounts for invoices and receipts.
How do I split GST from a total amount?
To split GST from a total amount, you need to separate the base amount and GST amount. If you have $110 total, divide by 11 to get the GST amount ($10), and multiply by 10 to get the base amount ($100). Our GST calculator Australia has a "Split GST" function that automatically calculates both the base amount and GST amount from any total, making it easy to see the breakdown for accounting or invoicing purposes.
