E-invoicing and Peppol compliance in Australia
E-invoicing in Australia uses the Peppol four-corner network governed by the ATO as the Australian Peppol Authority. All Commonwealth agencies must receive Peppol e-invoices, and tax invoices issued through Peppol must still meet the requirements of A New Tax System (Goods and Services Tax) Act 1999 (Cth). This guide sets out the 10 core obligations for businesses adopting Peppol.
Coverage
Australian businesses that issue tax invoices to Commonwealth agencies, large enterprises mandating Peppol with suppliers, and accounting software providers registered as Peppol access points.
Legal basis
A New Tax System (Goods and Services Tax) Act 1999 (Cth) ss 29-70, 29-75 (tax invoice requirements). Commonwealth Procurement Rules and the ATO Peppol Authority Rules (Australian Peppol PINT-A-NZ specification). Taxation Administration Act 1953 (Cth) sch 1.
The obligations
Register with a Peppol access point
Engage an accredited access point provider or register directly so the business receives a Peppol ID and can exchange invoices on the network.
Issue invoices in the correct PINT-A-NZ format
Use the Australian and New Zealand Peppol International (PINT-A-NZ) specification for structured invoice data, including mandatory fields for ABN, GST and line items.
Preserve tax invoice requirements
An e-invoice must still satisfy tax invoice requirements — supplier identity, ABN, GST amount, description, date and the words "tax invoice" where required.
Validate the counterparty Peppol ID
Before sending, validate the buyer's Peppol participant identifier (typically an ABN) and that they are able to receive the intended document type.
Issue and store adjustment notes electronically
Credit and debit notes issued over Peppol must meet adjustment note content rules and be linked to the original invoice for GST reconciliation.
Retain e-invoices for five years
Retain structured e-invoice data and any human-readable rendering for at least five years from the date of the transaction or decision it supports.
Comply with Commonwealth receipt mandate
When supplying a Commonwealth agency, be ready to send invoices via Peppol as agencies are required to receive e-invoices and pay promptly on receipt.
Secure the access point integration
Apply authentication, encryption in transit and role-based controls to the Peppol access point and any middleware that signs outbound invoices.
Map internal ERP fields to PINT-A-NZ
Document the mapping from the ERP or accounting system to every mandatory Peppol field so the invoice renders identically for tax and audit purposes.
Monitor network changes and disruptions
Track updates to the PINT-A-NZ specification, access point outages and ATO Authority notices so invoicing continues without breaching payment terms.
What happens if you do not comply
Non-compliant tax invoices can lead to denied GST input tax credits for the buyer and ATO compliance action for the supplier. Failure to meet Commonwealth receipt requirements may exclude suppliers from Commonwealth procurement under the Commonwealth Procurement Rules.
Reporting requirements
There is no standalone Peppol return, but GST on e-invoices must still be reported through the Business Activity Statement under the Taxation Administration Act 1953 (Cth). Access points report service incidents to the ATO Peppol Authority.
What firms should do today
- Select an ATO-accredited Peppol access point and document the integration
- Map every ERP invoice field to the PINT-A-NZ specification
- Test invoice and adjustment note flows with a pilot customer before go-live
- Train AP and AR teams on exception handling when Peppol delivery fails
- Update the record-keeping policy to cover five-year retention of structured data
