Working out GST for your Australian business
The Goods and Services Tax is a flat 10% that applies to most sales in Australia. Getting the GST component right matters for quoting, invoicing and lodging your Business Activity Statement (BAS). Use this calculator to add GST to a GST-exclusive price, or to strip the GST out of a total that already includes it — a common task when you receive a supplier invoice or set a retail price.
Practical GST tips for businesses
- To add GST, multiply the net price by 1.1; the GST portion is 10% of the net price.
- To find the GST inside a GST-inclusive total, divide the total by 11.
- Keep tax invoices for purchases so you can claim eligible GST credits.
- Track the GST you collect separately so it's ready when your BAS is due.
- Confirm whether your goods or services are taxable, GST-free or input-taxed.
