Austria has no B2B e-invoicing mandate and will follow EU ViDA, not lead
Austria mandates e-invoicing only for central-government suppliers (since 2014) and has no domestic B2B mandate. It uses a post-audit model with on-demand SAF-T reporting, not real-time clearance. ViDA will drive future changes from 2030 onward.
Austria operates a post-audit e-invoicing model limited to central-government B2G transactions, with no domestic B2B mandate or real-time reporting requirement. The country is an early B2G adopter but will align B2B and digital reporting only when EU ViDA obligations take effect from 2030.
Austria’s e-invoicing scope: B2G only
Austria mandates structured e-invoicing only for suppliers to central federal government bodies, a requirement in force since 1 January 2014. All other transactions. B2B, B2C, and sub-central government. remain voluntary.
Foreign suppliers to the Austrian federal government face the same e-invoicing obligation as domestic ones. They must submit invoices “to the extent technically possible” through the national platform or the Peppol network.
How it works: post-audit, not clearance
Austria operates a post-audit model. There is no government clearance, no invoice pre-validation for tax purposes, and no real-time reporting. The Federal Ministry of Finance (BMF) runs the central platform e-rechnung.gv.at through the Business Service Portal (USP). Invoices flow through either manual upload, web service, or the Peppol network.
For B2B transactions, there is no prescribed platform or format. Parties exchange invoices by mutual agreement. email, PDF, XML, or EDI. provided they guarantee authenticity of origin, integrity of content, and legibility.
Mandatory formats: ebInterface and Peppol BIS 3.0
B2G suppliers must use one of two formats:
- ebInterface (Austrian national XML standard, versions 6.0 or 4.3)
- Peppol BIS Billing 3.0
Both are aligned to the EU standard EN 16931. Austria maintains two Core Invoice Usage Specifications (CIUS): AT NAT for national VAT compliance and AT GOV for government procurement.
For B2B, no format is mandatory. Unstructured formats such as PDF remain valid where the recipient agrees.
SAF-T reporting: on-demand, not periodic
Austria introduced the OECD Standard Audit File for Tax (SAF-T) in 2009. It remains on-demand only. The tax authority can request SAF-T data ahead of an audit, but there is no periodic (monthly or annual) filing obligation.
A reported “relaunch” with periodic elements, mentioned for 2024, did not materialise into a mandatory obligation.
Austria’s SAF-T is comparatively light on data demands compared to periodic-SAF-T countries such as Poland or Portugal.
Archiving and retention
E-invoices must be retained for 7 years from the end of the year in which the invoice was issued. Capital goods, notably real estate, must be kept for 10 years.
The central platform does not relieve taxpayers of their own statutory retention duty. Digital archiving is allowed, including storage abroad, provided online access is ensured. Authenticity, integrity, and legibility must be maintained throughout the retention period.
No penalties specific to e-invoicing
Austria has no dedicated e-invoicing penalty regime. For B2G, enforcement is operational: non-conforming invoices are rejected by government systems, causing payment delay rather than a fine.
Penalties attach to underlying VAT and record-keeping breaches under the VAT Act (UStG 1994), Federal Fiscal Code (BAO), and Fiscal Penal Act (FinStrG).
ViDA will drive future change
Austria is aligned on B2G e-invoicing and EN 16931 format but behind on domestic B2B e-invoicing and digital reporting. The EU’s “VAT in the Digital Age” (ViDA) initiative, adopted 11 March 2025 and in force 14 April 2025, will reshape Austria’s obligations.
Under ViDA, near-real-time digital reporting for intra-Community B2B transactions applies from 1 July 2030, replacing the EC Sales List for in-scope transactions. Member States with domestic real-time regimes must harmonise by 2035.
Austria has not yet exercised ViDA’s new right to introduce domestic mandatory B2B e-invoicing without prior derogation.
What businesses should do now
Austrian suppliers to the federal government must maintain Peppol and ebInterface 6.0 capability. Older ebInterface versions (4.0, 4.1, 4.2) have been discontinued.
All businesses trading intra-EU should align invoice data models to EN 16931 and the updated EN 16931-1:2026 (released 18 March 2026) in anticipation of ViDA’s digital reporting requirements. Early Peppol adoption future-proofs for both a potential domestic B2B mandate and ViDA cross-border reporting.
Monitor official sources (BMF and the Austrian legal database RIS) for any legislative developments regarding a domestic B2B e-invoicing mandate or periodic SAF-T obligations. As of 2 July 2026, neither has been enacted.
SME impact: low burden today
Because B2B e-invoicing is voluntary, the compliance burden is broadly neutral to positive. Free government tools on e-rechnung.gv.at and the Business Service Portal provide manual entry, guidance, and support. The Federal Economic Chamber (WKÖ) offers a Word plug-in and ebInterface tooling.
Common Austrian ERP packages (BMD, RZL, SAGE Österreich) support native ebInterface and Peppol export. Cross-border SMEs, especially those trading with Germany where B2B e-invoicing is phasing in, increasingly adopt e-invoicing voluntarily to stay competitive.
