Electronic invoicing compliance guide for Australia

Australia has adopted Peppol as its national e-invoicing framework, with Commonwealth Government agencies required to both send and receive Peppol e-invoices since July 2023. While mandatory B2B e-invoicing has not yet been legislated, the ATO actively promotes adoption and the Government has consulted on broader mandates. This guide covers the current legal framework, practical compliance steps, and what to expect as Australia moves toward structured electronic invoicing.

Peppol e-invoicing: the current legal framework

The core e-invoicing developments in Australia centre on the Peppol network, adopted as the national standard in 2019. The ATO operates as the Australian Peppol Authority. Commonwealth Government agencies must receive and send Peppol e-invoices. State and territory governments are at various stages of adoption.

While the Australian Government has not yet mandated B2B e-invoicing, the ATO's promotion of Peppol and the Government's consultation on broader adoption signal that a mandate may follow. Businesses trading with government agencies are already required to support Peppol for government invoices.

The legal basis for electronic invoicing in Australia sits within the A New Tax System (Goods and Services Tax) Act 1999, which permits electronic tax invoices provided they meet GST requirements, and the Electronic Transactions Act 1999, which establishes the legal validity of electronic records.

GST Record-Keeping Requirements

The ATO requires all businesses registered for GST to maintain records that support their Business Activity Statements (BAS) for at least 5 years. These records must be maintained in a form that allows the ATO to access them during a review or audit.

GST record-keeping requirements include:

• The time of supply (tax point)
• The value of the supply (net and GST)
• The rate of GST charged
• Whether the supply is taxable, GST-free, or input-taxed

For businesses using Peppol e-invoicing, the structured data within the UBL format satisfies these requirements, provided the data is complete and accurate.

Peppol in the Australian public sector

Commonwealth Government agencies have been required to receive Peppol e-invoices since 1 July 2022 and to send them since 1 July 2023. The Department of Finance coordinates e-invoicing policy, and the ATO manages the technical infrastructure as the Peppol Authority.

State and territory adoption varies:

Peppol adoption beyond the public sector

Major Australian accounting software providers -- including Xero, MYOB, Reckon, and Sage -- support Peppol sending and receiving. The ATO reports that Peppol traffic in Australia has grown by over 50% year-on-year, driven primarily by government mandates but with increasing private sector uptake.

What the ATO requires for invoice records

The ATO's record-keeping guidance specifies that businesses must keep records of all transactions, including tax invoices, for 5 years from when they were prepared or the transaction completed (whichever is later).

For businesses issuing paper invoices, the data must still be entered into accounting software. The original paper invoice can be retained as the legal document, but the ATO encourages digital record-keeping.

International e-invoicing landscape: comparison with Australia

Electronic invoicing regulations vary significantly across the region and globally. Understanding the differences matters for businesses trading cross-border.

For Australian businesses trading cross-border, compliance may require supporting multiple formats: UBL 2.1 for Peppol (Australia, NZ, Singapore), FatturaPA for Italy, Factur-X or CII for France, and XRechnung for Germany.

Document retention and audit trails

Australian tax law requires businesses to retain invoices and supporting documents for five years. The Corporations Act 2001 requires financial records to be kept for seven years.

For electronic invoices, the retention requirement applies to the original digital format. Printing an electronic invoice and storing the paper copy does not satisfy the requirement if the original was in structured electronic form.

Automated document verification workflows can significantly reduce the compliance burden. By validating invoice data at the point of receipt -- checking ABNs, verifying amounts, matching to purchase orders -- businesses can catch errors before they enter the BAS return.

Preparing for mandatory e-invoicing in Australia

The Australian Government has signalled that broader B2B e-invoicing mandates are under consideration. The Treasury consultation on e-invoicing explored options for expanding adoption beyond the public sector.

Practical steps for Australian businesses

Assess your current invoicing process. Map how invoices are created, sent, received, and stored. Identify manual steps and paper-dependent processes.

Connect to the Peppol network. Register with a certified Peppol Access Point using your ABN as the participant identifier. This positions your business ahead of any future mandate.

Choose software that supports Peppol. Select accounting and ERP software that can generate and receive Peppol BIS invoices natively. Xero, MYOB, and other major platforms support this.

Implement pre-submission validation. Validate invoices against the A-NZ Peppol BIS specification before sending to catch errors at the source.

FAQ

Is e-invoicing mandatory in Australia?

E-invoicing via Peppol is mandatory for Commonwealth Government agencies. For the private sector, Peppol adoption is strongly encouraged but not yet mandated. The Government has consulted on broader mandates and the direction of travel is clear toward wider adoption.

What format should Australian businesses use for e-invoicing?

Peppol BIS Billing 3.0 (based on UBL 2.1) with the A-NZ extension is the Australian standard. It is used by government agencies and supported by all major Australian accounting software providers.

How does Peppol work for cross-border invoicing?

Peppol is an international network operating across 38 countries. Australian businesses connected to Peppol can exchange e-invoices with businesses in other Peppol countries (NZ, Singapore, EU member states) without additional technical integration.

What penalties apply for failing to keep proper invoice records?

The ATO can impose penalties for failure to maintain proper records. Under the Taxation Administration Act 1953, penalties range from 20 to 75 penalty units (AUD 6,260 to AUD 23,475 as of 2026) depending on the circumstances. Failure to keep records can also lead to estimated assessments where the ATO determines tax liability based on available information.

Will Australia adopt real-time clearance like Italy or France?

The Australian Government has not indicated a preference for a clearance model. Given Australia's existing post-audit approach via Peppol and the ATO's focus on digital record-keeping through BAS reporting, a Peppol-based post-audit model with enhanced digital reporting is considered more likely by most tax advisers.
