What must an Australian tax invoice include?

The ATO requires the following on a valid tax invoice (for sales over $82.50 GST-inclusive):

  • The words “Tax Invoice” clearly shown
  • Your ABN (Australian Business Number)
  • The date the invoice was issued
  • Seller's name and contact details
  • A brief description of the goods or services sold
  • The GST amount (or a statement that the total price includes GST)
  • The total price of the sale

InvoKit handles all of this automatically. Just enter your details and download.

Australian invoice FAQs

Do I need an ABN to issue an invoice in Australia?

If you are running a business in Australia and registered for GST, yes — your ABN must appear on every tax invoice. If you are not registered for GST (under $75,000 annual turnover), you still need an ABN but the invoice does not need to say 'Tax Invoice'.

When do I need to charge GST?

If your business has a GST turnover of $75,000 or more per year ($150,000 for non-profits), you must register for GST and charge 10% on taxable supplies. Ride-share and taxi drivers must register regardless of turnover.

What is the difference between a tax invoice and a regular invoice?

A tax invoice includes your ABN, the words 'Tax Invoice', and a breakdown of GST. It is required for sales over $82.50 (GST-inclusive). Regular invoices are for sales below that threshold or for GST-free goods and services.

Is InvoKit free to use for Australian businesses?

Yes — you can create and download invoices for free. Free invoices include a small InvoKit watermark. Upgrade to remove it.
