How to fill in a compliant tax invoice

A valid Australian tax invoice has to carry the seven ATO elements: the words “Tax Invoice”, your business name, your ABN, the date of issue, a description (and quantity) of what was sold, the GST amount or a statement that the price includes GST, and the extent to which each sale is taxable. For any sale of $1,000 or more (including GST) you also add the buyer’s identity or ABN.

The GST formula

If you’re registered for GST (compulsory once your turnover reaches $75,000, or $150,000 for not-for-profits), apply the flat 10% rate to each line:

• GST = GST-exclusive amount ÷ 10
• Total (inc. GST) = GST-exclusive amount × 1.1
• Removing GST from a GST-inclusive price = price ÷ 11

Worked example

A tradie invoices $1,000 (ex-GST) for a job — say $600 labour and $400 in materials. GST is $1,000 ÷ 10 = $100. The invoice shows a $1,000 subtotal, $100 GST, and a $1,100 total payable. If the customer instead agreed a $1,100 GST-inclusive price, the GST already inside it is $1,100 ÷ 11 = $100.

Frequently asked questions

Everything you need to know about invoice requirements in Australia.

What must be included on a tax invoice in Australia?

The ATO requires 7 elements on a valid tax invoice: (1) that the document is intended as a tax invoice, (2) the seller's identity (name or business name), (3) the seller's ABN, (4) the date of issue, (5) a brief description of the items or services sold (including quantity where applicable), (6) the GST amount (if any) — or a statement that the total price includes GST, and (7) the extent to which each sale is a taxable sale. For sales of $1,000 or more (including GST), you must also include the buyer's identity or ABN.

Do I need to charge GST on my invoices?

You must charge GST if your business is registered for GST. Registration is mandatory once your annual turnover reaches $75,000 ($150,000 for not-for-profits). If you're below the threshold, GST registration is optional. If you're not registered, you cannot charge GST and your invoices should state prices as GST-free.

What's the difference between a tax invoice and a regular invoice?

A tax invoice is a specific document required under Australia's GST system. It includes your ABN, itemised GST amounts, and meets ATO formatting requirements. A regular invoice may not include these elements. If you're GST-registered, you must issue tax invoices for sales of $82.50 (including GST) or more when the buyer requests one.

How long do I need to keep copies of my invoices?

The ATO requires you to keep invoice records for at least 5 years from the later of: when the record was prepared or obtained, or when the related transaction was completed. This applies to both invoices you issue and invoices you receive. For records relating to depreciating assets or capital gains, the 5 years runs from when the relevant CGT or depreciation event ends. Digital copies (such as PDFs) are acceptable as long as they're legible and stored securely.

Can I use these templates for ABN-only businesses (sole traders)?

Yes. These templates work for all Australian business structures including sole traders, partnerships, companies, and trusts. Every template includes a field for your ABN. If you're a sole trader not registered for GST, simply leave the GST fields blank or mark items as GST-free.

Which invoice template is best for tradies (plumbers, electricians, builders)?

Use the Tradie Invoice template. It separates a materials list from a labour breakdown so you can show job details, parts and time on the same tax invoice — the layout plumbers, electricians and builders need for job invoicing. It is GST-line ready and includes the ABN and "Tax Invoice" elements the ATO requires. If you raise the same jobs repeatedly, you can also create them automatically (with GST applied) in OneBookPlus instead of filling in a template each time.

Is there an invoice template for a cleaning business?

Yes. For one-off cleans use the Standard Invoice template; for ongoing commercial-cleaning contracts use the Recurring Invoice template, which adds a billing period and frequency so you can bill the same client each month. Both are GST-compliant and ABN-ready. List each clean as a line item with its rate, apply 10% GST if you are registered, and the template totals the subtotal, GST and amount due for you.
