Australia e-Invoicing Guide

Australia has no e-invoicing mandate in tax law, and the ATO receives no invoice data. The obligation that does exist is a procurement one, and it binds government buyers rather than the businesses that sell to them. The Australian Taxation Office became the Australian Peppol Authority on 31 October 2019 , accrediting service providers and setting the local requirements for the Peppol standards, and it runs adoption as a programme rather than an enforcement exercise. Everything outside the Commonwealth supply chain, B2B and B2C alike, is voluntary.

The duty falls on Non-corporate Commonwealth Entities, one of the three categories of government body set out in the Department of Finance PGPA Act Flipchart , alongside corporate Commonwealth entities and Commonwealth companies. They have had to be able to receive Peppol eInvoices since July 2022, and ATO guidance for government sets two further steps: eInvoicing must account for 30% of all invoices received by 1 July 2026, and automated processing and sending must be enabled by December 2026, with progress reported quarterly to the Australian Peppol Authority. Those two targets are the interim step. The ATO describes the government as establishing eInvoicing as the default method for exchanging invoice information for all non-corporate Commonwealth entities, with transitional arrangements commencing immediately , while Treasury works with the Department of Finance on the policy that will carry the mandate. The instrument itself is not yet in force, and no date has been announced for it.

Three claims about Australia circulate widely and none of them holds. The first is that the ATO sees invoices for audit purposes. It states the opposite in bold on its own site: it does not receive a copy of eInvoices and cannot view the contents of any invoice moving between businesses. The second is that suppliers to government must send eInvoices. No supplier is required to do anything; the requirement sits on the entity receiving the invoice. The third is that a Business eInvoicing Right created some form of B2B obligation. It was a consultation idea, and the ATO records that the findings have not been enacted by government .

The framework is trans-Tasman by design. On 25 October 2018 the Australian Assistant Treasurer and the New Zealand Minister for Small Business signed the Trans-Tasman Electronic Invoicing Arrangement to build a common approach across both countries, and the ATO took the Peppol Authority role a year later. The first hard incentive arrived on 1 January 2020, when the Supplier Pay On-Time or Pay Interest Policy introduced five day payment terms where Peppol capability exists, initially only for contracts up to $1 million. The Digital Business Plan of September 2020 then announced that the Commonwealth would mandate eInvoicing for all agencies by 1 July 2022. What took effect on that date was narrower: the Australian Government Architecture records that from July 2022 use of eInvoicing functionality is mandatory for non-corporate Commonwealth entities, and the revised payment policy dropped the $1 million threshold on the same day.

Two attempts to extend the mandate to business came to nothing. Treasury consulted in November 2020 on options for mandatory adoption by businesses and again from 15 December 2021 to 25 February 2022 on supporting business adoption of eInvoicing , the paper that floated the Business eInvoicing Right. Both closed without being enacted. The thread that did continue runs through procurement: on 5 December 2023 the Minister for Small Business released the Government response to the Statutory Review of the Payment Times Reporting Act 2020 , and Budget 2024-25 on 14 May 2024 put $23.3 million behind increased adoption to improve cash flow, disrupt payment redirection scams and boost productivity. The ATO traces the default-in-procurement commitment to that Budget.

The technical migration ran alongside all of this and is now finished. OpenPeppol's Australian country profile records the A-NZ Peppol BIS Billing extension as mandatory only until 15 November 2024 and PINT A-NZ Billing as mandatory from that date. The specification repository run by the two Peppol Authorities then records PINT A-NZ as the sole mandatory specification since 15 May 2025, the old extension as deprecated on 22 May 2025, and its removal from the Peppol network on 31 March 2026, at which point the artefacts and schematron files were taken down. Version 1.1.2 of the specification was published on 8 December 2025 and is current.

Only Non-corporate Commonwealth Entities are bound. Corporate Commonwealth entities and Commonwealth companies sit outside the requirements, and the ATO encourages rather than compels them. Within scope, the obligation is capability first and volume second: an entity must be able to receive, then work its suppliers up to 30% of all invoices received by 1 July 2026, then automate both processing and sending by December 2026. Reporting has been running since July 2024 and more than 80% of entities now report their volumes; from July 2025 the ATO also asks which finance systems they run, whether those systems can process and send automatically, and what the upgrade plans are.

Suppliers carry no legal duty at all, and the pull on them is commercial. Under RMG 417 , where an entity and its supplier can both handle eInvoices and have agreed to use them, the maximum payment term is five calendar days against twenty for everything else. The clock is not generous about when it starts: payment times only begin once the entity has acknowledged satisfactory delivery and accepted a correctly rendered invoice, which is to say after a three-way match. Beyond payment speed, agencies work eInvoicing in through supplier onboarding, contract renewals and new tenders rather than through any rule that binds the supplier directly.

Adoption below the Commonwealth is real but voluntary. More than 300 state, territory and local government organisations are on the network, with most agencies in New South Wales, South Australia and the Australian Capital Territory able to receive, many Queensland agencies able to both send and receive, Western Australia running a programme towards larger-scale implementation, Victoria committed and Tasmania aiming to reach all its agencies. The Northern Territory took a different route with InvoiceNTG, a web portal that is not Peppol. Ordinary record-keeping rules apply to eInvoices with no special treatment: most business records must be kept five years , counted from when the record was prepared or obtained or the transaction completed, whichever is later.

Australia runs a four-corner Peppol model with no clearance step and no central government platform. A supplier sends to its access point, which passes the invoice across the network to the buyer's access point for delivery. The ATO accredits both access points and service metadata publishers, applies Peppol Authority Specific Requirements on top of the international rules, and monitors compliance, but sits outside the flow of documents. Accreditation is mutually recognised with New Zealand, so a provider cleared in one country can operate in the other, and providers already accredited by another Peppol Authority use a streamlined process.

The document specification is PINT A-NZ , the Australia and New Zealand specialisation of the Peppol International billing process, shared with New Zealand so that a trans-Tasman invoice needs no translation. It is localised for Australian tax requirements, and the ATO accepts that an eInvoice satisfies the requirement that a document is intended to be a tax invoice where it is issued in accordance with the A-NZ invoice specification and carries all the mandatory data, even when it does not use the words 'Tax Invoice'. The current version is 1.1.2 for both the billing and the self-billing processes, the latter optional for service providers to support. Most businesses are addressed by Australian Business Number under International Code Designator 0151 , though some use a different designator, particularly if they also trade overseas. Publishing receiver details to the Peppol Directory is mandatory in Australia, which is what makes the directory usable for checking whether a trading partner can be reached. Peppol carries more than invoices: catalogues, orders, despatch advices and invoice responses are all available without local extension.

Nobody outside the transaction sees the invoice. The ATO is explicit that it does not receive a copy of any eInvoice and cannot view the contents of documents moving between businesses, and OpenPeppol records that tax compliance is not the driver for eInvoicing in Australia. That is the structural difference between the Australian model and the clearance and continuous transaction control regimes used across Latin America, southern Europe and much of the Gulf, and it explains why adoption here has to be sold on cash flow and administrative savings rather than compelled by a tax authority.

There is no financial penalty for failing to adopt eInvoicing in Australia, for businesses or for government entities. The requirements sit in procurement policy and Peppol Authority guidance rather than in the GST or tax administration law, so nothing attaches to a business that keeps sending PDFs. What the framework offers instead is a cash-flow difference: five calendar days rather than twenty under RMG 417. Where an entity misses its maximum payment terms it must calculate interest at the ATO general interest charge rate and pay it to the supplier if the amount accrued exceeds A$100.

For Commonwealth entities the consequence of falling behind is visibility rather than a fine. Progress against the 30% and automation targets is reported quarterly to the Australian Peppol Authority, which uses the data to direct support at the entities that need it. The ATO also notes on its own page for RMG 417 that the payment terms policy is under review, so the five day term is the position today rather than a fixed feature of the regime.
