What is the Australian GST rate?

Australia's Goods and Services Tax (GST) rate is 10%. It is a broad-based tax levied on most goods, services, and other items sold or consumed in Australia. The rate has been 10% since GST was introduced on 1 July 2000.

How is GST calculated when adding it to a net price?

Multiply the net (ex-GST) price by 1.1. For example, a $100 net price becomes $110 gross. The GST amount is $10, which is exactly 10% of the net price.

How do I extract GST from a GST-inclusive price?

Divide the gross (GST-inclusive) amount by 11. For example, $110 gross ÷ 11 = $10 GST, leaving a net price of $100. This is the standard ATO formula for finding the GST component.

Not everything in Australia has GST — which items are exempt?

Basic food, some health and medical services, some education courses, childcare, and exports are GST-free. Financial services and residential rent are input-taxed (no GST charged). Check the ATO website or consult a tax professional for a full list of GST-free and input-taxed supplies.

Do I need to register for GST?

You must register for GST if your business has a GST turnover of $75,000 or more (or $150,000 for non-profit organisations). Ride-share and taxi drivers must register regardless of turnover. Businesses below the threshold may register voluntarily.

Is this calculator suitable for BAS reporting?

This tool is designed for quick price calculations and gives mathematically correct GST amounts. For official BAS lodgment, always reconcile against your accounting system and consult the ATO guidelines or a registered BAS agent, as rounding rules and specific supply classifications can affect the exact figures.
