Free Invoice Generator for Australia

Australia calls it a 'tax invoice', and the ATO is specific about what one must contain: your ABN, the words 'Tax invoice', and the GST treatment of every line. Miss the ABN and your client may have to withhold 47% of the payment.

What a Australia invoice must include

  • The words 'Tax invoice' prominently displayed
  • Your business identity and ABN
  • The date the invoice was issued
  • A brief description of each item sold, with quantity
  • The GST amount payable — shown separately, or a statement like 'Total price includes GST'
  • Which items are taxable vs GST-free, for mixed supplies
  • For sales of $1,000 or more: the buyer's identity or ABN

Tax note: GST at 10%. Tax rules change — confirm anything unusual with your accountant.

Tips for invoicing in Australia

  • If your prices include GST, say so explicitly on the invoice — 'Total includes GST of $X'. Ambiguity causes disputes.
  • For invoices over $1,000, always collect and show the buyer's ABN. It's mandatory, not optional.
  • A client asked for a tax invoice? GST-registered businesses must provide one within 28 days of the request.
  • Electronic PDF invoices are fully valid — the ATO cares about content, not paper.

Frequently asked questions

When do I have to register for GST?

When your GST turnover reaches $75,000 in a 12-month period ($150,000 for not-for-profits). Below that, registration is voluntary.

What if my sale is GST-free?

Don't show a GST amount. State that the supply is GST-free, but still include the other required fields (ABN, date, description, price).

How long must I keep tax invoices?

At least five years, in a readable form — PDFs from a generator like Billia count.
