GST (Goods and Services Tax) is a value-added tax of 10% on most goods and services in Australia. Businesses registered for GST must include GST in their prices and remit it to the Australian Taxation Office (ATO).
Frequently Asked Questions
What is the GST rate in Australia?
The standard GST rate in Australia is 10%. Some goods and services may be GST-free or input-taxed, but most standard goods and services are subject to the 10% rate.
What's the difference between GST inclusive and exclusive?
GST Inclusive: The price already includes GST. For example, if you see a price of $110, the GST ($10) is already included in that amount.
GST Exclusive: The price does not include GST. You need to add GST to the base price. For example, if the price is $100, you'll add $10 GST to make it $110 total.
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. Some businesses choose to register voluntarily even if below this threshold.
Is this calculator free to use?
Yes! Our GST calculator is completely free to use. No registration required, no hidden fees. Just enter your amounts and calculate GST instantly.
Can I use this calculator for other countries?
