What Must Be on an Australian Tax Invoice?
Under ATO rules, a tax invoice must clearly show it is a tax invoice and include your identity, ABN, issue date, what you sold, GST details, and the total payable. Sales of $1,000 or more including GST also need the buyer's identity or ABN (ATO tax invoices guide).
- The words "Tax Invoice" shown clearly on the document
- Your business identity (name or trading name)
- Your Australian Business Number (ABN)
- The date the invoice was issued
- A brief description of goods or services sold, including quantity and price
- The GST amount payable, or a statement that the total price includes GST
- The extent to which each sale is a taxable sale
| Sale amount | Additional requirements |
|---|---|
| Under $1,000 (inc. GST) | Seller identity, ABN, issue date, item description, GST amount or inclusive statement, and total payable. |
| $1,000 or more (inc. GST) | All standard tax invoice fields plus the buyer's identity or ABN clearly shown on the invoice. |
There were 2.73 million businesses actively remitting GST in Australia in 2024-25, with small businesses making up 97.3% of GST-registered entities (Australian Small Business and Family Enterprise Ombudsman, 2025).
GST vs Non-GST Invoices: When to Charge GST
Charge 10% GST only if your business is registered for GST. Registration is required when annual turnover reaches $75,000 ($150,000 for non-profits). If you are not registered, issue a regular invoice without GST and do not use the words "Tax Invoice".
GST-free supplies can include most basic food, some education and health services, childcare, and exports. Mixed invoices must clearly show which line items are taxable. This generator lets you toggle GST on or off to match your registration status.
- Add GST: multiply the ex-GST price by 1.1
- Find GST in an inclusive price: divide the total by 11
- Report and pay GST through your Business Activity Statement (BAS)

Frequently Asked Questions
Common questions about free invoice generators, ATO tax invoice requirements, GST, ABNs, and record keeping for Australian businesses.
Is this invoice generator really free?
Yes. invoice.net.au is free to use with no sign-up, no credit card, and no invoice limits. Fill in your details, add line items, and download or print a PDF tax invoice in your browser whenever you need one.
What is required on a tax invoice in Australia?
A valid Australian tax invoice must show the words "Tax Invoice", your business identity, your ABN, the issue date, a description of what you sold, the GST amount (or a statement that the total includes GST), and the total payable. For sales of $1,000 or more including GST, you must also include the buyer's identity or ABN (Australian Taxation Office, 2026).
Do I need an ABN to invoice in Australia?
You can issue an invoice without an ABN, but it is strongly recommended to have one. Without an ABN on your invoice, the payer may need to withhold 47% of your payment under PAYG withholding rules. Getting an ABN is free through the Australian Business Register.
What is the difference between an invoice and a tax invoice?
A regular invoice is a request for payment that any business can issue. A tax invoice is a specific document required from GST-registered businesses. It must include the words "Tax Invoice", your ABN, and a clear GST component. Only GST-registered businesses should issue tax invoices.
When do I need to register for GST?
You must register for GST when your business has a GST turnover of $75,000 or more per year, or $150,000 for non-profit organisations. You must register within 21 days of exceeding that threshold. You can also register voluntarily below the threshold to claim GST credits on business purchases.
How do I calculate GST on my invoices?
GST in Australia is 10% of the taxable amount. To add GST to a price, multiply by 1.1 (for example, $100 becomes $110 including GST). To find the GST in a GST-inclusive price, divide by 11 (for example, $110 includes $10 GST). This generator calculates GST automatically when you toggle GST registered.
How long should I keep invoice records?
The ATO requires you to keep invoice records for at least five years from when you prepared or obtained them, or five years after the last related transaction, whichever is later. Digital copies are acceptable if they are legible and stored securely.
Can I use this for sole trader invoicing?
Yes. This tool is built for Australian sole traders, freelancers, contractors, and tradies. Use your individual ABN on the invoice, add your line items, and export a professional PDF. Toggle GST on only if you are registered for GST.
What is the $82.50 threshold?
If you are GST-registered, you must provide a tax invoice when a customer asks for one on taxable sales over $82.50 including GST. You have 28 days to issue it. Sales of $82.50 or less do not require a tax invoice unless the customer requests one.
Does this work on mobile?
Yes. The invoice generator works in your mobile browser. Fill in your details, add line items, and print or save as PDF from your phone or tablet. The layout adapts to smaller screens so you can invoice on site or on the go.
