Australian GST Calculator 2026

This calculator works out Australian Goods and Services Tax, the 10 percent tax charged on most goods and services sold in Australia, so you can move between GST-inclusive and GST-exclusive prices in a single step. Enter an amount and the GST percentage, which defaults to the standard 10 percent rate but can be edited if you need a different figure, and the tool instantly returns two results: Minus Australian GST, the GST-exclusive price found by stripping GST out of a figure you entered as inclusive, and Plus Australian GST, the GST-inclusive price found by adding GST on top of a figure you entered as exclusive. Each result also shows the dollar amount of GST involved. This suits an Australian business working out how much tax to charge, an accountant checking figures for a GST return, or a New Zealander buying from an Australian supplier who wants the true cost before or after tax. Most goods and services in Australia attract GST, though basic food, healthcare, education, childcare, precious metals and exports are commonly exempt or GST-free, so confirm your transaction is actually taxable before relying on the figures. Businesses registered for GST must charge it on sales and can claim credits on purchases, and this calculator is a quick working tool rather than a substitute for lodging an activity statement with the Australian Taxation Office.

The Australian Goods and Services Tax (GST) is a value-added tax (VAT) introduced on July 1, 2000, as part of a comprehensive tax reform program. It is a tax on the consumption of goods and services in Australia and is collected by businesses on behalf of the Australian government. The GST has a standard rate of 10%, and it is applied to most goods and services sold or consumed in Australia. 

Overview of Australian GST:

Australian GST is a tax that is applied to most goods and services sold or consumed in Australia. The tax is collected by businesses on behalf of the Australian government, and businesses are required to register for the GST if they have an annual turnover of $75,000 or more. Once registered, businesses are required to charge the GST on their sales and are entitled to claim a credit for the GST paid on their purchases.

The GST applies to a wide range of goods and services, including:

1. Goods imported into Australia
2. Goods sold in Australia
3. Services provided in Australia
4. Digital products and services supplied from overseas to Australian consumers

There are some exemptions to the GST, including certain food items, medical services, and educational courses. However, businesses that provide exempt goods or services are not entitled to claim a credit for the GST paid on their purchases.

GST Accounting:

Businesses that are registered for the GST are required to account for the tax in their business activities. This involves charging the GST on sales, claiming a credit for the GST paid on purchases, and reporting the GST on their activity statements.

Example 1: GST on Sales

Let's assume that a business sells a product for $100, and the GST rate is 10%. The business would need to charge $110 ($100 + 10% GST) to the customer. The $10 collected as GST is then remitted to the Australian Taxation Office (ATO) when the business lodges its activity statement.

Example 2: GST on Purchases

Let's assume that a business purchases inventory for $1,000, and the GST rate is 10%. The business would be entitled to claim a credit of $100 ($1,000 x 10%) for the GST paid on the purchase. The credit is then applied to the GST payable on sales.

Example 3: GST Reporting

Businesses that are registered for the GST are required to lodge an activity statement with the ATO on a regular basis. The activity statement reports the GST collected on sales, the GST paid on purchases, and any adjustments or other transactions that affect the GST liability. The GST liability is then paid to the ATO, or a refund is claimed if the GST credits exceed the GST payable.

Penalties and Interest:

Businesses that fail to register for the GST when required or fail to account for the tax correctly may be subject to penalties and interest. The ATO has the power to impose fines and interest charges on businesses that do not comply with the GST laws. Additionally, businesses that make false or misleading statements on their activity statements may be subject to criminal charges.

Conclusion:

The Australian GST is a tax on the consumption of goods and services in Australia. It is collected by businesses on behalf of the Australian government and is applied to most goods and services sold or consumed in Australia. Businesses that are registered for the GST are required to account for the tax in their business activities, including charging the GST on sales, claiming a credit for the GST paid on purchases, and reporting the GST on their activity statements. Failure to comply with the GST laws may result in penalties and interest charges, as well as criminal charges for making false or misleading statements.
