How the invoice generator works

Fill in your business details and the client’s, add line items, and the invoice updates as you type. If you are registered for GST the document is a tax invoice with 10% GST added to each taxable line; if not, it is a plain invoice with a note that no GST has been charged. A checklist beside the preview shows whether the document meets the ATO’s content rules, including the buyer-identity requirement for sales of $1,000 or more. Press Download PDF to print or save it through the browser; the print view contains only the invoice.

GST on invoices

GST is 10% of the GST-exclusive price. Quote prices excluding GST and the generator adds it; tick prices include GST and it divides by 11 to show the GST component. Registration is compulsory at $75,000 of annual GST turnover and optional below that. An unregistered business must not charge GST or issue a tax invoice.

  • Recurring invoices, email sending or payment tracking.
  • Foreign-currency invoices or export (GST-free) rules beyond marking a line GST-free.

Frequently asked questions

What must a tax invoice include in Australia?

A tax invoice for a sale under $1,000 must show the words “tax invoice”, the seller’s identity and ABN, the date, a description of what was sold including quantity and price, the GST amount (or a statement that the total includes GST) and which items are taxable. For sales of $1,000 or more it must also identify the buyer by name or ABN. The generator’s checklist tracks each item.

Do I need to charge GST on my invoice?

Only if you are registered for GST. Registration is compulsory once your GST turnover reaches $75,000 a year ($150,000 for non-profits) and optional below that. If you are not registered, do not add GST or call the document a tax invoice; issue a plain invoice, and the generator adds a note that no GST has been charged. Ride-share and taxi drivers must register regardless of turnover.

Is there a free ABN invoice template?

Yes. This generator produces an invoice with your ABN shown in the standard 2-3-3-3 format, validated against the ABR check-digit rule so a typo is caught before it reaches a client. Fill in the details, download the PDF, and use “New invoice” to keep your business and payment details for the next one with the number incremented.

How is GST calculated on an invoice?

GST is 10% of the GST-exclusive price: an $800 service attracts $80 GST for a total of $880. If you quote GST-inclusive prices, the GST component is the total divided by 11 ($880 ÷ 11 = $80). The generator handles both: tick “prices include GST” and it works backwards from the inclusive amount. GST-free items, such as most basic food, health and education, are excluded line by line.

Do I need a tax invoice for sales under $82.50?

No. For sales of $82.50 or less (GST-inclusive) you are not required to issue a tax invoice, though you can, and buyers can claim GST credits with a receipt or bank statement instead. Above $82.50 a registered seller must give a tax invoice within 28 days if the buyer asks. Most businesses simply issue one for every sale.

Can I invoice without an ABN?

You can, but a business paying you must withhold tax at the top rate (47%) from the payment unless you quote an ABN or the payment is under $75, is private in nature, or you provide a “statement by a supplier” explaining why no ABN is needed. Hobby income can fall in that category. For any regular business activity, getting an ABN is free through the Australian Business Register.

Is my invoice data stored anywhere?

Only in your own browser’s local storage, so your details are there next time you open the page on the same device. Nothing is sent to AussieCalcs or any server; the PDF is created by your browser’s print function. Clearing your browser data removes the draft. For saved clients, numbering across devices and recurring invoices, a paid tier is planned.
