Tax invoice generator

Fill in your details, add your lines, and download a tax invoice as a PDF. It checks the details the ATO requires a tax invoice to show, strips or adds GST line by line, and builds the PDF on your own machine — nothing about your client, your bank details or your prices is sent anywhere.

What has to be on a tax invoice

The ATO's requirement depends on the size of the sale. For a taxable sale under $1,000, the invoice must show enough information to work out all seven of these:

  1. That the document is intended to be a tax invoice.
  2. The seller's identity.
  3. The seller's ABN.
  4. The date the invoice was issued.
  5. A brief description of the items sold, including quantity and price.
  6. The GST amount payable — shown separately, or as a statement that the total price includes GST where the GST is exactly one-eleventh of the total.
  7. The extent to which each sale is a taxable sale.

Sales of $1,000 or more must also show the buyer's identity or ABN. The checklist beside the form tracks all of these as you type and tells you which one is missing.

When you must supply one

If a customer asks for a tax invoice you must provide one within 28 days, unless the sale was $82.50 including GST or less. Keep in mind that a customer needs a valid tax invoice before they can claim a GST credit, which is why they ask.

Mixed taxable and GST-free sales

If an invoice covers both taxable and non-taxable items, it must clearly show which items are taxable, the GST payable on those items, and the total. Unticking the GST box on a line here marks it as non-taxable on the invoice, and the checklist flags that the invoice contains a mix.

GST rounding on a multi-line invoice

GST is calculated and rounded to the cent. On an invoice with several lines there are two legitimate approaches: round the GST on each line and add them up, or work out GST once on the subtotal. They can differ by a cent. This generator uses the per-line method — the same as most accounting software, so your figures should agree — and it tells you when the subtotal method would have produced something different, so a one-cent discrepancy from a supplier is explainable rather than mysterious.

About the PDF

The PDF is written directly by this page's own JavaScript — a small amount of code that assembles the file in memory, with no PDF library and no third-party service. That is why the download works with no internet connection and why your client's name, your bank details and your prices never leave your computer.

Common questions

What must an Australian tax invoice include?
The ATO lists seven details for a taxable sale under $1,000: the document is intended to be a tax invoice, the seller's identity, the seller's ABN, the date it was issued, a description of the items including quantity and price, the GST amount payable (shown separately or as a statement that the total price includes GST), and the extent to which each sale is taxable. For sales of $1,000 or more you also need the buyer's identity or ABN.
Does a tax invoice have to say 'tax invoice'?
It has to be clear that the document is intended to be a tax invoice. Writing the words 'Tax invoice' at the top is the simplest way to satisfy that, and this generator always includes it. If a customer asks for a tax invoice you must provide one within 28 days, unless the sale was $82.50 including GST or less.
Can I generate a tax invoice if I am not registered for GST?
You can generate an invoice, but it should not be called a tax invoice and it must not show GST, because you are not charging any. Untick the GST column and change the document title to 'Invoice' — the checklist above will flag whichever of the two you have chosen.
Is my data uploaded anywhere?
No. The PDF is assembled in JavaScript inside your browser using the Blob API. There is no server-side code on this site, no analytics and no third-party script. You can disconnect from the internet after the page loads and the invoice will still generate.
Why is the total sometimes a cent different from my accounting software?
Because GST is rounded per line. On a multi-line invoice, rounding each line and adding them up can differ by a cent from working out GST once on the subtotal. Both are accepted by the ATO. This generator rounds per line, shows the GST for each line, and tells you when the subtotal method would have given a different answer.
Can I save an invoice and come back to it?
Not from this page — deliberately. Saving your client list or bank details would mean storing them, and this tool keeps nothing at all. Use your accounting software for records you need to keep; use this for a one-off invoice you need right now.
