What is a Tax Invoice in Australia? (ATO Requirements)

Last updated: 22 July 2026

A tax invoice is a legally required document in Australia that includes the GST amount and specific ATO-mandated details, allowing GST-registered businesses to claim input tax credits. You must issue a tax invoice instead of a standard invoice if you are registered for GST and the sale is over $82.50 (including GST).

In this guide, we will break down the ATO requirements so you can ensure your business remains compliant.

Tax Invoice vs. Regular Invoice

A common question is: what is the difference between a tax invoice and a regular invoice?

• Regular Invoice: Used by businesses that are not registered for GST. It requests payment for goods or services but does not include any GST amount.
• Tax Invoice: Used by businesses that are registered for GST. It includes the GST amount and specific ATO-mandated details, allowing the buyer to claim input tax credits.

Tax Invoice vs. Receipt

While a tax invoice is a request for payment, a receipt is a proof of payment.

• Tax Invoice: Issued before or at the time of payment to request funds and show the GST component.
• Receipt: Issued after payment has been received to confirm the transaction is complete. (Learn more about why you need to issue payment receipts).

Do Sole Traders Need to Issue a Tax Invoice?

Yes, if you are a sole trader registered for GST, you must issue a tax invoice for any taxable sale over $82.50. However, if your sole trader business has an annual turnover of less than $75,000, you are not legally required to register for GST. If you are not registered for GST, you simply issue a regular invoice without GST.

When do I need to issue a tax invoice?

If you are registered for GST, you must issue a tax invoice for any taxable sale of more than $82.50 (including GST).

Your customers need this tax invoice from you in order to claim a credit for the GST in the purchase price. If they request a tax invoice, you must provide one within 28 days of their request.

Tax Invoice Requirements in Australia (ATO Compliant)

According to the ATO, a valid tax invoice must include enough information to clearly determine the following seven details:

1. The Document Type: It must prominently state that the document is a "Tax Invoice".
2. The Seller's Identity: Your business name (or trading name).
3. The Seller's ABN: Your Australian Business Number.
4. The Date: The date the tax invoice was issued.
5. The Items: A brief description of the items sold or services provided, including the quantity (if applicable) and the price.
6. The GST Amount: The GST amount payable. This can be listed separately for each item, or as a statement that "Total price includes GST".
7. The Buyer's Identity (For sales of $1000 or more): If the sale is $1,000 or more, the invoice must also show the buyer's identity or ABN.

Example of checking the GST Amount

There are two primary ways to show GST on your invoice:

• GST Inclusive: You can state that the total price includes GST (e.g., "Total: $110.00 inclusive of GST").
• GST Exclusive: You can show the price without GST, then add the GST amount on a separate line (e.g., "Subtotal: $100.00, GST: $10.00, Total: $110.00").

Does it have to be a PDF or paper?

No. The ATO accepts electronic tax invoices. What matters is the information contained within the document, not the medium. A PDF attached to an email is the standard practice for modern businesses.

How to Make a Tax Invoice Instantly

Creating a tax invoice manually in Word or Excel can be tedious and prone to errors. If you forget your ABN or miscalculate the GST, your client's accountant might reject the invoice, delaying your payment.

The easiest way to generate an ATO-compliant tax invoice is to use a dedicated tool.

Beyond the Basics: Look Professional

While meeting the ATO requirements is the legal minimum, your invoice is also a representation of your brand. A clean, professional-looking invoice builds trust and often gets paid faster.

Make sure your invoices include:

• Your company logo
• Clear payment terms (e.g., "Net 14" or "Due upon receipt")
• Your bank details or payment links clearly visible

By using a tool like Invoice Buddy, you can automatically generate beautiful invoices, save your client details for next time, and even let your clients pay you instantly via credit card.
