Guidance

Tax invoice vs regular invoice in Australia

GST-registered businesses generally use tax invoices for taxable sales, while businesses that are not registered for GST generally issue regular invoices and should not charge GST. If GST registered is turned off in this tool, the preview is labelled Invoice rather than Tax invoice and GST is not added. If a customer asks for a tax invoice, GST-registered businesses generally need to provide one within 28 days, except for sales of $82.50 including GST or less.

• GST registered on: the output is labelled Tax invoice and shows GST.
• GST registered off: the output is labelled Invoice and does not add GST.
• Customers generally need a valid tax invoice to claim GST credits for purchases over $82.50 including GST.
• For higher-value invoices, such as taxable sales of $1,000 or more including GST, buyer identity or ABN may be required.

Checklist

What to include on an Australian invoice

A practical Australian invoice usually includes clear supplier identity, ABN where applicable, client identity, invoice number, issue date, description of what was supplied, quantity, price, GST amount where relevant, total payable, due date, and payment instructions. This tool prompts for those fields but still allows draft generation if something is missing.

• Business name and contact details.
• ABN where applicable.
• Client name and address or email.
• Invoice number, issue date, due date, and payment terms.
• Line item descriptions, quantities, unit prices, GST treatment, and totals.

Calculation

How GST is calculated on an invoice

This invoice with GST calculator uses three simple treatments. GST included means the entered line amount already includes GST, so GST is calculated as total divided by 11. GST excluded means the entered line amount is before GST, so 10% is added. GST-free means no GST is added for that line. The tool then shows subtotal, GST, discount, and total due rounded to two decimal places.

• GST included: GST = line total / 11.
• GST excluded: GST = line subtotal x 10%.
• GST-free: GST = 0.
• Discount is subtracted after GST in this simple draft.

Comparison

When to use GST included vs GST excluded

Use GST included when the amount you agreed with the customer already includes GST, such as a total package price. Use GST excluded when your quote or rate is before GST and GST needs to be added on top. Use GST-free only when the supply is GST-free for your circumstances. If you are unsure, check current ATO guidance or ask a registered professional.

Examples

Invoice examples for freelancers and contractors

A freelancer might invoice one design project as a GST excluded service, then show GST and total due separately. A contractor might invoice hourly labour with a quantity and rate, then add payment terms such as 7, 14, or 30 days. A small business might include a GST-free line item beside a taxable service, then use the preview to check that the total due still makes sense.

• Freelance consulting: 10 hours x hourly rate, GST excluded.
• Project work: one fixed fee, GST included.
• Mixed invoice: taxable services plus GST-free items.
• Contractor invoice: line items plus payment instructions and due date.

Mistakes

Common invoice mistakes to check before sending

Small invoice mistakes can delay payment or create confusion. Before sending, check the business name, ABN, client name, invoice number, dates, GST registration status, line item descriptions, payment terms, bank details, and total due. The inline warnings are a draft checklist, not a substitute for accounting review.

• Charging GST when not registered for GST.
• Forgetting ABN or supplier identity details where applicable.
• Using a duplicate invoice number.
• Mixing GST included and GST excluded prices without checking totals.
• Missing payment instructions or a clear due date.

Trust signal

General use only

This tool is for general use and works in your browser. Review the invoice before sending it to a customer. It is not accounting, legal, or tax advice, and it does not decide whether your business should be GST registered or whether a supply is taxable, GST-free, or input taxed.
