WHAT HAS TO BE ON IT.

These are the elements the ATO requires on a tax invoice. Miss one and a customer’s bookkeeper can hand it straight back, which is a fortnight added to when you get paid.

  • ✓The words "tax invoice"

    A tax invoice has to say so prominently. If you are not registered for GST you must NOT call it a tax invoice — it is just an "invoice".

  • ✓Your business name

    The seller's identity. Your trading name is fine as long as it's the name you actually trade under.

  • ✓Your ABN

    Required on a tax invoice, and worth having on every invoice: a business customer who isn't given an ABN has to withhold 47% of the payment and send it to the ATO.

  • ✓The date you issued it

    The issue date, not the date you did the work.

  • ✓What you did, itemised with quantity and price

    A description of the items sold, including quantity and price. One line reading "labour" is not a description, and it is the line customers query.

  • ✓The GST amount

    Shown separately, or stated as "Total price includes GST". Only if you are registered — if you are not, there must be no GST on the invoice at all.

  • ✓Who the invoice is for

    The buyer's identity or ABN, required once the sale reaches $1,000 including GST.

AND THE ONES THAT GET YOU PAID FASTER.

Not required by anyone. Every one of them removes a step between your customer and the pay button.

  • A unique invoice number

    Not strictly required by the ATO, but you'll want one the first time a customer says they already paid, and your accountant will want it at tax time.

  • A clear due date

    A real date — "due 30 July" — beats "within 14 days". People pay dates, not durations.

  • How to pay you

    BSB and account number on the invoice itself. Every extra step between the customer and paying is a day added.

QUESTIONS.

What must be on a tax invoice in Australia?

A valid tax invoice must show the words "tax invoice", the seller's identity, the seller's ABN, the date it was issued, a description of what was sold including quantity and price, the GST amount (or a statement that the total includes GST), and the extent to which each sale is taxable. Once the sale reaches $1,000 including GST it must also identify the buyer, by name or ABN.

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

A tax invoice is a specific document you can only issue if you're registered for GST — it accounts for the GST you've collected and lets a business customer claim it back. If you're not registered for GST you issue a plain invoice, you must not charge GST on it, and you shouldn't call it a tax invoice. Getting this wrong by charging GST you're not registered to collect is one of the more expensive mistakes a new sole trader makes.

Do I have to put my ABN on an invoice?

On a tax invoice, yes. On any invoice, you want to: if you don't quote an ABN, a business customer is required to withhold 47% of the payment and send it to the ATO. You'd get it back at tax time, but you'd be waiting a year for money you've already earned.

When do I have to give someone a tax invoice?

A customer registered for GST can ask you for a tax invoice for any taxable sale of $82.50 or more including GST, and you have to provide it within 28 days of them asking. Below that you don't have to, though there's no reason not to.

Do I need to identify the customer on the invoice?

Once the sale is $1,000 or more including GST, yes — the invoice has to show the buyer's identity or their ABN. A name is enough. Below that it isn't required, but putting it on makes the invoice much easier for the customer's bookkeeper to process, which means it gets paid sooner.

Is this invoice template free?

Yes. Fill it in, print it or save it as a PDF from the print dialog. Nothing is sent anywhere — it all stays in your browser — and there's no signup, no email and no watermark.

How do I number my invoices?

Any sequence works as long as each number is used once and they run in order: INV-0001, INV-0002. The ATO doesn't mandate a format. What matters is that you can find a specific invoice the day a customer says they already paid it.

A guide, not tax advice — your accountant knows your situation. Requirements checked against the ATO’s tax invoice guidance in July 2026.

DO IT ONCE, NOT EVERY JOB.

A template still means typing it out every time and remembering to chase it. Agentize raises the invoice from the finished job, numbers it, sends it in your name, and keeps following it up until the money lands.
