Everything You Need To Know About Invoicing In Australia

Some Australian businesses must charge a Goods and Service Tax (GST) of 10%. Find out if you have the same obligation and learn more about GST in general below.

GST & non-GST businesses:

When invoicing in Australia, different rules apply for non-GST-registered and GST-registered businesses. If you're business that is not registered for GST, you send standard invoices. On the other hand, if you're GST-registered business, you send tax invoices to your clients. The Australian Taxation Office (ATO) defines six reasons for mandatory registration for GST.

In that case, you have to apply for an Australian Business Number (ABN) and display it on your invoices especially related to sales of $82.50 (including GST) or more. There are several things that must be displayed on invoice in Australia - the word "Tax invoice", your and your client's details, your ABN, items sold with respective quantity and price, invoice issue date and GST amount payable.

The standard payment term in Australia is 30 days, but it can differ from business to business. It's usually upon both parties and their initial agreement. It must be agreed upon beforehand to ensure smooth financial transactions.


Value added tax (VAT) in Australia is defined as Goods and Service Tax (GST) and for many cases it's 10%. There can be other taxes for individuals that are usually based on income.

Every Australian business needs to lodge an annual tax return, stating all your income and expenses for the previous financial year. A financial year starts on 01 July and finishes on 30 June next year.

If you register for GST, whether it is a voluntary or mandatory registration, you will be required to lodge your quarterly Business Activity Statements (BAS).

Frequently asked questions

What is an invoice?

An invoice is a commercial document issued by a seller to a buyer, detailing the goods or services provided with their corresponding costs. It serves as a formal request for payment, specifying the terms and conditions of the transaction. Generally, an invoice acts as a record of the sale and helps facilitate the payment process between the parties involved.

What is a tax invoice?

A tax invoice in Australia is a formal document that is provided by seller to a buyer. It contains details about the sale, detailing the goods or services provided, the total amount, and the GST (Goods and Services Tax). The Australian Taxation Office (ATO) requires businesses registered for GST to provide a tax invoice for sales of more than $82.50 (including GST). Tax invoice must include specific information such as the seller's personal details and Australian Business Number (ABN), issue and delivery date, items and their description, and the GST amount.

What is a proforma invoice?

A proforma invoice works as a preliminary bill document. It's sent to customer before the goods or services are delivered. It contains all the important information such as items and quantity, descriptions of items, prices and other terms and conditions. Unlike the regular invoice, proforma invoice gives an estimation or request for payment and it's not legally binding. On the other hand, once goods and services are delivered, regular invoice is sent that serves as a request for payment.

A proforma invoice is like a preliminary bill of sale. It's sent to buyers before a sale is finalized or before the goods are delivered. It gives a detailed preview of what the purchase will include, such as the types and quantities of items, their prices, and other important sale terms. However, unlike a final invoice, a proforma invoice is not a demand for payment. Instead, it's often used to give buyers an estimate of the cost for budgeting purposes or to complete customs documentation for international shipping.
