# Australia — Peppol e-invoicing via the ATO

Peppol PINT A-NZ · federal default by Dec 2026 · ATO Peppol Authority — regulator: [Australian Taxation Office (ATO)](<https://www.ato.gov.au/businesses-and-organisations/einvoicing>). _Facts last refreshed: 2026-07-13._

Coverage model

Flowie operates a registered Peppol Access Point in this jurisdiction **directly** where we hold national accreditation, **or via a vetted local partner** registered with the in-country regulator where on-the-ground presence is required (KSeF, SDI intermediario, ZATCA service-provider, etc.). Either way, you call the same `POST /v1/documents/send`. 

## TL;DR

  * The ATO is Australia's **Peppol Authority** (since 31 Oct 2019); all federal NCEs (Non-Corporate Commonwealth Entities) accept Peppol e-invoicing.
  * Format: **PINT A-NZ** — joint Peppol CIUS with New Zealand (replaced the legacy A-NZ BIS extension on 15 May 2025).
  * Federal procurement target: **30% Peppol invoices by 1 Jul 2026** , automated send-and-receive across NCEs by **December 2026**.
  * **No B2B mandate** ; adoption is voluntary but strongly encouraged via federal procurement preference and 5-day payment terms.
  * Flowie operates an Australian-registered Peppol AP (`0151:`) — directly, or via a specialized local partner where in-country presence is required.

**2026-07-01**|  Federal NCEs| 30% of received invoices via Peppol target.

## Background

Australia adopted Peppol in 2019 as a deliberate procurement-modernisation move and made the ATO the national Peppol Authority. Federal Non-Corporate Commonwealth Entities (NCEs) had to be Peppol-receive-capable by July 2022; the 2024–25 Federal Budget commits them to Peppol-default exchange by December 2026, with an interim 30% receipt target on 1 July 2026.

There is **no B2B mandate** in the current federal plan, but the government nudges adoption via federal procurement preferences (faster onboarding, shorter payment terms) and via the Strategic Reform Agenda. Adoption is strongest in B2G, large enterprise, and accounting-software-led SMB segments (Xero, MYOB, QuickBooks all support Peppol natively).

Format is **PINT A-NZ** , a joint Australia–New Zealand CIUS on Peppol International Invoice. The legacy A-NZ Peppol BIS 3.0 extension was deprecated on 15 May 2025.

## Format profile

  * **PINT A-NZ** on UBL 2.1 — joint AU–NZ CIUS.
  * Seller and buyer **ABN** (Australian Business Number, 11 digits) used as Peppol participant ID under scheme `0151`.
  * GST breakdown required; rounding rules per ATO.
  * B2G: BuyerReference must equal the agency-issued purchase order or contract reference.



## Required fields

  * seller.abnstring (11 digits)required

Australian Business Number; used as `0151` Peppol participant ID.

  * seller.gstRegisteredbooleanrequired

If true, GST lines must show ATO-compliant tax codes.

  * buyerReferencestringrequired for B2G

Agency-issued purchase order / contract reference; without it, B2G recipients reject.

**Federal NCEs via Peppol**| `0151:`| <https://www.ato.gov.au/businesses-and-organisations/einvoicing>  
  
All federal Non-Corporate Commonwealth Entities are Peppol-reachable via their ABN. State and local government adoption varies — Flowie's directory tracks coverage.

## B2B reporting / clearance

_No central B2B reporting hub — pure transmission only._

## Error codes

_Generic Peppol BIS schematron error codes apply (`BR-*`, `EN16931-*`); no country-specific overlays._

## FAQ

### Is there real-time tax-authority reporting?

No — Australia has not adopted a 5-corner CTC model. The ATO receives no real-time copy of B2B invoices; Peppol delivery is purely 4-corner.
