E-Invoicing in Austria:
B2G rules, ebInterface & Peppol

Last update: 2026, September 15

Summary

Austria has required structured e-invoices for suppliers of the Federal Government since 2014. The framework relies on the e-Rechnung.gv.at platform and the Peppol network, using ebInterface or UBL invoice formats.

B2G Transactions

Mandatory e-invoicing for transactions with federal public administrations

Suppliers of the Austria Federal Government must send electronic invoices through the Peppol network (Peppol BIS 3.0 format) or through the e-rechnung.gv.at central platform (ebInterface XML format or Peppol BIS 3.0).

E-invoicing is also possible with multiple local public administrations.

B2B Transactions

No e-invoicing obligation

No e-invoicing or e-reporting obligation applies to business-to-business transactions in Austria, but e-invoicing is possible upon mutual agreement between trading partners.

B2C Transactions

No e-invoicing obligation

No e-invoicing or e-reporting obligation applies to business-to-consumer transactions in Austria.

What the Law Says

B2G E-Invoicing

B2G e-invoicing has been mandatory for suppliers of Austrian Federal public administrations.

This obligation began on January 1, 2014, following the publication of Section 5 of the Austrian ICT Consolidation Act (IKTKonG) [↗︎]. Paper and PDF invoices are therefore not considered structured e-invoices and are not accepted as a standard submission method for federal B2G transactions.

Many other local public administrations (such as states, municipalities or cities) can also receive structured e-invoices. The government maintains a list of participating public invoice recipients [↗︎].

The Peppol network is allows suppliers to submit structured electronic invoices to Austrian public administrations, using the Peppol BIS Billing 3.0 specification in UBL syntax.

The e-Rechnung.gv.at central platform [↗︎] is another channel for suppliers to submit structured e-invoices to Austrian public administrations. The platform accepts the Austrian ebInterface XML invoice format (v4.3 and above), as well as the Peppol BIS Billing 3.0 format.

Depending on the targeted public administration, additional information, as highlighted in the e-Rechnungsverordnung, Section 4 [↗︎], may be needed such as the supplier number, purchase order reference, applicable order-position number, IBAN/BIC, payment terms and the supplier’s email address.

The B2G e-invoicing mandate applies to Austrian suppliers. Foreign suppliers to Federal Government departments are also covered where “technically feasible”, with no further official explanation of the term.

Invoices must generally be archived for seven years.

B2B E-Invoicing

B2B e-invoicing is voluntary in Austria.

Businesses may agree to exchange invoices in any format accepted by both parties, including:

Paper invoices
PDF invoices sent by email
EDI, including established formats such as EDIFACT
Structured electronic invoices sent through the Peppol network

No domestic B2B e-invoicing mandate has been announced. However, Austria will need to implement the EU’s VAT in the Digital Age (ViDA) reform. From July 1, 2030, intra-EU B2B transactions will be subject to e-reporting requirements based on structured electronic invoicing.

Like other European countries, Austria may take the implementation of ViDA as an opportunity to introduce mandatory B2B e-invoicing for domestic transactions, although no such measure has been announced yet.

Invoices must generally be archived for seven years.

B2C E-Invoicing

Austria does not have a B2C e-invoicing or e-reporting mandate.

Companies may continue to issue business-to-consumer invoices and receipts through their usual channels, including paper invoices, PDF invoices sent by email and printed receipts.

Technical Details (B2G)

The method for submitting a B2G invoice depends on the public administration receiving it. Federal public administrations require structured e-invoices, while other public administrations may or may not accept them. Suppliers should check the recipient’s specific requirements before sending an invoice.

Overview

Austria provides two official channels for exchanging B2G structured e-invoices:

The Peppol network
The e-rechnung.gv.at central platform

The government has published comprehensive B2G guidelines [↗︎] explaining both options in detail, as well as comprehensive lists of public administrations [↗︎] (federal and local) able to receive electronic invoices.

E-Invoicing via the Peppol network

For public administrations that can receive electronic invoices, the Peppol network is one of the channels through which suppliers can transmit their invoices.

Invoices sent to Austrian public administrations through Peppol must be addressed to the central participant ID 9915:b [↗︎]. The actual recipient is then determined from the purchase order reference included in the invoice.

Electronic invoices must be sent in Peppol BIS 3.0 format, in compliance with the official format specifications [↗︎]. Austria also maintains two national Core Invoice Usage Specifications (CIUS):

CIUS AT NAT [↗︎] for B2B use
CIUS AT GOV [↗︎] for additional B2G rules

Peppol BIS 3.0 is compliant with the European Norm 16931, and more details on EN 16931 compliance [↗︎] are also available in German.

E-Invoicing via the Central Platform

For public administrations that can receive electronic invoices, the e-rechnung.gv.at central platform [↗︎] is the other channel through which suppliers can transmit their invoices.

The platform is administered by the BMF (Ministry of Finance) and requires initial user authentication through the Unternehmensservice Portal (USP – Business Service Portal) [↗︎]. Alternatively, companies can avoid this authentication step by using service providers that are registered with the USP [↗︎].

Once authenticated, companies can choose from the following invoice delivery methods [↗︎] to the central platform:

Manual input in an online form
Manual upload of an e-invoice
Automated transmission via web service

The formats accepted [↗︎] on the e-rechnung.gv.at central platform are:

The local ebInterface format, developed and maintained by the AUSTRIAPRO association.
- Legacy versions (v4.2 and below) were deprecated in 2022.
- The currently accepted versions are v4.3, 5.0, 6.0 and the latest 6.1 version.
- Versions 5.0 and above are compatible with EN 16931 in the sense that they can be transformed into EN 16931-compliant invoices.
The Peppol BIS 3.0 format.

Depending on the targeted public administration, some additional fields [↗︎] may need to be included in the e-invoice, such as the purchase order reference and supplier number, or other special fields [↗︎] tied to the BBG [↗︎] (Austria Public Procurement Agency).

Testing and validation

Before submitting an XML invoice, suppliers can use the e-Rechnung.gv.at Test Upload [↗︎] to check its technical validity. The tool supports all accepted invoice formats and does not submit the invoice for processing or payment.

Specific XML schemas are also available to help suppliers check certain Federal Government requirements before submitting an invoice.

The Invoicing Hub Word

Austria

With more than a decade having passed since B2G e-invoicing was made mandatory at the federal level, Austria has been an early adopter of e-invoicing in Europe.

The government provides comprehensive guidelines, responsive support and diverse options for companies to submit their e-invoices to public administrations, ranging from manual input to automated submission via web service or the Peppol network. In essence, B2G e-invoicing at the Austrian federal level operates smoothly.

However, despite this early implementation, Austria has not progressed beyond its initial B2G obligation, and no B2B e-invoicing mandate has been introduced. As a result, traditional invoicing in paper or PDF remains prevalent in Austria.

This may change in the coming years as Austria will inevitably implement the EU’s VAT in the Digital Age (ViDA) reform. The reform could indeed provide an opportunity for Austrian authorities to consider implementing broader domestic e-invoicing requirements.
