Free Invoice Template Australia (ATO-Compliant, 2026)

Q: Is there a free ATO-compliant invoice template for Australia?

Yes — you can download a free Word or PDF invoice template, or use a free invoicing tool that generates a compliant invoice every time. The static template route works but you have to maintain it yourself; the tool route stays current automatically when ATO rules update.

Q: What must a free Australian invoice template include?

The words “Tax Invoice” (if GST-registered), your business name, your ABN, the invoice date, a unique invoice number, a description of the goods or services, the total in AUD, and the GST amount if applicable. For invoices over $1,000, also the buyer’s identity or ABN.

Q: Can I use a Word or Excel template?

Yes — Word and Excel templates are legal as long as the final invoice (typically exported as PDF) contains the required ATO fields. The downside is you have to update the template yourself when your details change, and there is no built-in numbering or record-keeping.

Q: Do I need to charge GST on the template?

Only if you’re registered for GST. Registration is mandatory once your annual turnover reaches $75,000. Below that, your template should not show GST or use the words “Tax Invoice” — it is just an “Invoice”.

Q: How is a free invoicing app different from a free template?

A template is a static document you fill in each time. An app stores your business details once, auto-numbers invoices, tracks paid vs unpaid, generates PDFs, and stays current with ATO rules. For most sole traders the app route saves hours over a year and removes the risk of an out-of-date template.

Quick answer

A free, ATO-compliant Australian invoice template must include the words “Tax Invoice” (if GST-registered), your business name, ABN, invoice number, date, line item descriptions, GST amount if applicable, and the AUD total. You can use a Word or PDF template, or use a free invoicing app that generates a compliant invoice in seconds and keeps itself up to date.

The required fields, in plain English

For a normal invoice under $1,000 (where you’re GST-registered):

The words “Tax Invoice” at the top of the page.
Your business name or registered trading name.
Your ABN.
The date the invoice is issued.
A unique invoice number (sequential, no gaps).
A description of each item (with quantity and unit price).
The GST amount, separately or on each line.
The total in AUD.

For invoices $1,000 or more, you must also include the buyer’s identity (name or business name) or ABN. If you’re not GST-registered, the words “Tax Invoice” must not appear and there is no GST line. Full breakdown in what must be on a tax invoice.

A simple template (free, copy-paste)

The bare-minimum layout. Paste this into a Word, Pages, or Google Doc, fill in the bracketed fields, and export as PDF:

TAX INVOICE
INV-[NUMBER] — [DATE]

From:
[Your Business Name]
ABN [Your ABN]
[Address line 1]
[Suburb State Postcode]
[email] / [phone]

To:
[Client Name]
[Client business / ABN if invoice is $1,000+]
[Client address]

———————————————————————————————————————————————————————————
Description                                       Amount
———————————————————————————————————————————————————————————
[Service or item, qty, rate]                      $[Amount]
[Service or item, qty, rate]                      $[Amount]
———————————————————————————————————————————————————————————

Subtotal:                                         $[Subtotal]
GST (10%):                                        $[GST]
Total (AUD):                                      $[Total]

Due [Due date] (Net [days])

Payment:
   BSB / Account: [BSB] / [Account]
   Account name:  [Your Business Name]
   PayID:         [email or phone]

For non-GST businesses (turnover under $75k), replace “TAX INVOICE” with “INVOICE”, remove the GST line, and add: “No GST has been charged. This business is not registered for GST.” See how to invoice without GST for the full non-GST template.

Where static templates fall short

A free Word or PDF template gets the job done on day one. It starts to drag once you have repeat work:

You manually number every invoice. Skip a number once and your audit trail has a gap. See how to number invoices.
You re-type the same client details over and over. Typos in ABNs and email addresses cause real disputes.
You have no record of what’s paid. Tracking happens in your head or a spreadsheet, until you forget.
When ATO rules change (the $1,000 buyer-ABN threshold, the wording on non-GST invoices), you have to update the template yourself.
The PDF has no built-in audit trail — no record of when it was sent, when it was viewed, when it was paid.

The always-compliant alternative

A free invoicing app removes the maintenance burden entirely:

You enter your ABN, business name, and bank details once.
Every invoice auto-numbers in sequence.
GST toggles automatically based on whether you’re registered.
The $1,000 buyer-ABN rule is enforced automatically.
Every invoice you’ve ever sent is stored and searchable for the ATO’s 5-year retention rule. See how long to keep invoices.
PDFs are generated identically every time.

Free Invoice App handles all of this on its Free tier (7 sends per month) at no cost — no credit card required. Create a free account and your first invoice goes out in under 60 seconds.

When a template is still the right call

A static template is a reasonable choice if any of these apply:

You invoice less than once a month and don’t want to maintain an account.
You have a very particular layout that you’ve already perfected in Word or InDesign.
Your accountant has set up a templated spreadsheet that already feeds into their system.

For everyone else, the Free Invoice App route saves hours over a year and removes the risk of a stale template.

What “ATO-compliant” actually means

There is no ATO “approval” or “certification” for invoice templates. Any document that contains the required fields is compliant; any document missing one or more required fields is not. The ATO doesn’t care which tool made it. Be wary of templates that claim “ATO-approved” — the ATO doesn’t issue approvals. What matters is the fields.

Common template mistakes

The errors that most often invalidate a template:

Missing ABN. Without an ABN, the client must withhold 47% of the payment. See do you need an ABN?
Using “Tax Invoice” when you’re not GST-registered. Tax Invoice is reserved for GST-registered suppliers; using it when you’re not registered is a misrepresentation.
Duplicate or skipped invoice numbers. The ATO expects sequential numbering with a clear audit trail.
Missing buyer ABN on $1,000+ invoices. Required for buyer GST credit claims; failing this can prompt buyer queries. See tax invoices over $1,000.
Showing GST when not registered. Charging GST without being registered is illegal and must be refunded plus reported to the ATO.

How Free Invoice App handles this

Free Invoice App generates an ATO-compliant invoice every time, on every plan. The Free plan covers 7 sends a month with no card required. Branding, GST, ABN, sequential numbering, $1,000 buyer-ABN, payment terms, and bank details all populate automatically from your one-time setup. Get started free.
