How It Works

This australia gst calculator uses established formulas to provide accurate results.

The basic rule:

  • GST = Ex-GST amount x 10%
  • Inc-GST price = Ex-GST amount x 1.1
  • Ex-GST from inclusive = Inc-GST price / 1.1
  • GST component from inclusive = Inc-GST price / 11

Results are estimates. Consult a professional for critical decisions.

Frequently Asked Questions

What is the GST rate in Australia?

Australia's GST rate is a flat 10% on most goods and services. Unlike some countries, Australia has a single GST rate with no reduced or elevated rates. Some items are GST-free, including basic food, education, health, and exports.

How do I calculate GST from a total price?

To find the GST in a GST-inclusive price, divide by 11. For example, an item costing A$110 includes A$10 GST (A$110 / 11 = A$10). The GST-exclusive price is A$100 (A$110 / 1.1).

What items are GST-free?

GST-free items include most basic food (bread, milk, fruit, vegetables, meat), medical services, education courses, exports, and some childcare. Prepared foods, restaurant meals, and snack foods are taxable.

When do I need to register for GST?

You must register for GST if your business has an annual turnover of $75,000 or more ($150,000 for non-profits). Below this threshold, registration is optional. Registered businesses charge GST and claim input tax credits.
