FAQs

What is the GST rate in Australia?

10%. Australia's Goods and Services Tax has been 10% since it was introduced on 1 July 2000. It applies to most goods and services sold or consumed in Australia.

How do I remove GST from a price that already includes it?

Divide the total by 11. If your invoice is $1,100, the GST component is $1,100 ÷ 11 = $100. The pre-GST amount is $1,000. Do not multiply by 10% — that gives the wrong answer.

When does a business have to register for GST in Australia?

When your annual GST turnover reaches or is likely to reach $75,000 ($150,000 for non-profits). Taxi and ride-share drivers must register regardless of turnover. Once registered, you must charge GST on taxable sales and lodge a BAS.

Which goods and services are GST-free in Australia?

Basic food (fresh fruit, vegetables, meat, bread), most medical and health services covered by Medicare, some education courses, exports, and some government charges. Always check the ATO's current list — assumptions can be wrong and penalties apply.

What is the difference between GST-free and input-taxed?

GST-free means no GST is charged on the sale, but the business can still claim GST credits on its purchases to make that sale. Input-taxed means no GST is charged on the sale and the business cannot claim GST credits. Residential rent is input-taxed. Fresh food is GST-free.

Can I claim GST credits on all my business purchases?

Only on purchases used for your business and for taxable or GST-free sales. You cannot claim GST credits on private expenses, purchases related to input-taxed sales (like residential rent), or purchases where there is no valid tax invoice over $82.50.

What should a valid tax invoice show in Australia?

The supplier's name and ABN, the date the invoice was issued, a description of the goods or services, the price including GST, and either the GST amount or a statement that 'the total price includes GST'. Invoices under $1,000 can use a simplified format.

Does GST apply to imported goods bought online from overseas?

Yes, since 1 July 2018. Overseas suppliers with Australian turnover above $75,000 must charge 10% GST on goods under $1,000 sold to Australian consumers. Goods over $1,000 have GST collected at the Australian border by the ATO.

What happens if I don't register for GST when I should?

The ATO can require you to pay GST on all sales back to the date you were required to register, plus penalties and interest. They can register you without your consent and impose penalties for failing to lodge a BAS.

How does GST work for accountants and BAS agents?

Accounting firms register clients for GST, reconcile GST collected against GST credits each quarter, and lodge the BAS. Ezyiah sits before this step — it categorises all transactions from bank statements, flags GST codes, and sends clean data to your accounting software so the BAS figures are already prepared when the accountant opens the file.
