Tax invoice

An invoice that meets ATO requirements so a registered buyer can claim a GST credit on the purchase.

What it means

A tax invoice is an invoice that contains the specific details the ATO requires for a GST-registered buyer to claim a GST credit. Beyond the usual invoice information, it typically must show that GST has been charged and identify the supplier's details in the required way.

Issuing correct tax invoices is part of meeting your GST obligations and helps your customers claim their own credits without delay.

Getting the details right

The exact content and format rules — including thresholds for what must be shown — are set by the ATO and can change, so confirm the current requirements with the ATO or your accountant. Raising compliant invoices through Merion invoicing helps you capture the required fields. See also GST.
