How to Calculate Australian GST

The Goods and Services Tax (GST) is a broad-based consumption tax of 10% on most goods, services, and other items sold or consumed in Australia. GST has been in place since July 1, 2000, and is administered by the Australian Taxation Office (ATO).

Important: Australia has a uniform 10% GST rate that applies nationwide. Unlike some countries with varying state or provincial taxes, the GST rate is consistent across all Australian states and territories.

Adding GST to a Price

When you need to add GST to a GST-exclusive price (common for business-to-business transactions), use this formula:

GST Amount = Base Price × 0.10
Total Price (Inc GST) = Base Price + GST Amount
Or simply: Total Price (Inc GST) = Base Price × 1.10

Example: If the base price is $100 (excluding GST):

GST Amount = $100 × 0.10 = $10.00

Total Price = $100 + $10.00 = $110.00

Removing GST from a Price

When you need to calculate the GST-exclusive price from a GST-inclusive price (common for retail transactions), use this formula:

Base Price (Ex GST) = Total Price ÷ 1.10
GST Amount = Total Price - Base Price
Or: GST Amount = Total Price × (1/11)

Example: If the total price is $110 (including GST):

Base Price = $110 ÷ 1.10 = $100.00

GST Amount = $110 - $100 = $10.00

Or: GST Amount = $110 × (1/11) = $10.00

Quick Tip: The ATO states that GST is 1/11th of the GST-inclusive price. This means for any price that includes GST, exactly 1/11th (approximately 9.09%) of that price is the GST component.

Understanding Australian GST

What is GST?

Goods and Services Tax (GST) is a value-added tax (VAT) system that applies a 10% tax at each stage of the supply chain. However, only the final consumer bears the full cost. Businesses registered for GST can claim credits for the GST they pay on business purchases, making GST a tax on consumption rather than on businesses.

Who Needs to Register for GST?

You must register for GST if:

  • Your business turnover is $75,000 or more per year - This includes all business income before expenses
  • Your non-profit organisation has a turnover of $150,000 or more per year - Higher threshold for registered charities and non-profits
  • You provide taxi, limousine, or ride-sharing services - Including Uber, DiDi, Ola drivers regardless of turnover
  • You want to claim fuel tax credits - Regardless of turnover, if you wish to claim fuel tax credits

If your turnover is below these thresholds, registration is optional. However, voluntary registration allows you to claim GST credits on business purchases.

GST Registration Process

To register for GST in Australia, you need:

  • An Australian Business Number (ABN)
  • To complete registration through ATO Business Portal or by phone
  • To choose your reporting period (monthly, quarterly, or annually)
  • To start charging GST from your registration date

How Businesses Report GST

Registered businesses report GST through Business Activity Statements (BAS):

  • Monthly: For businesses with turnover of $20 million or more, or who choose monthly reporting
  • Quarterly: Most common option for small to medium businesses
  • Annually: Available for businesses with turnover under $75,000 (voluntary registration)

In your BAS, you report the GST you collected on sales (GST on sales) and the GST you paid on business purchases (GST credits). The difference is what you pay to or receive from the ATO.

GST Exemptions and GST-Free Items

GST-Free vs Exempt: It's important to understand the difference. GST-free items don't include GST in the price, but you can still claim GST credits on related business purchases. Exempt items also don't include GST, but you cannot claim GST credits for them.

Can I claim GST credits on business purchases?
Yes, if you are registered for GST, you can claim credits (called input tax credits) for the GST included in the price of goods and services you buy for your business. This is claimed through your Business Activity Statement (BAS). The credits reduce the amount of GST you need to pay to the ATO, ensuring GST only applies to the final consumer.

BAS is lodged monthly, quarterly, or annually depending on your business turnover.
Is GST the same in all Australian states?
Yes, GST is a federal tax with a uniform rate of 10% across all Australian states and territories. Unlike countries with state or provincial sales taxes, Australia has a single GST system administered by the federal government through the ATO.
