Country deep dive
Austria was one of the earliest EU countries to mandate B2G e-invoicing, with a federal requirement in force since 1 January 2014 — years before most of its peers. B2B remains voluntary today, but that's under active review: the Finance Ministry has signalled a Peppol-based domestic mandate is coming, with a formal proposal expected in the third quarter of 2026, against a firm EU-law floor of July 2030 for cross-border B2B regardless of the outcome.
The Republic of Austria stops accepting paper invoices from suppliers to federal government bodies (IKTKonG §5, BGBl. I Nr. 35/2012). Invoices must be submitted electronically, either in the ebInterface XML format or as UBL via Peppol — one of the earliest B2G mandates in the EU.
The Federal Public Procurement Act 2018 (BVergG 2018, §368) broadens the existing e-invoicing obligation beyond core federal ministries to cover all central contracting authorities. Several of Austria's nine Länder (states) — including Vienna, Lower Austria, and Upper Austria — have since adopted comparable requirements of their own.
Austria has no domestic B2B e-invoicing or real-time reporting mandate today — B2B structured invoicing remains voluntary, though widely adopted, especially among businesses with EU trading partners already under mandatory regimes. The Finance Ministry (BMF) has signalled it may eventually pursue a Peppol-based approach, mirroring Belgium and the Netherlands, but as of August 2026 no formal proposal, consultation, or specific timeline has been published.
AUSTRIAPRO (the WKO's e-billing working group) is preparing ebInterface 7.0 for release in Q4 2026, adding a formal syntax binding to the European e-invoicing standard EN 16931. No mandatory migration from 6.0/6.1 has been announced, and development is proceeding with backward compatibility in mind.
Regardless of the outcome of any domestic B2B proposal, the EU's VAT in the Digital Age (ViDA) directive requires structured e-invoicing and digital reporting for cross-border B2B transactions from 1 July 2030 — confirmed EU law (Council Directive (EU) 2025/516, OJEU 25 March 2025).
Austria is unusual in accepting two genuinely distinct formats for the same B2G obligation: ebInterface, its own long-running national XML standard, and Peppol BIS 3.0. Both are EN 16931-aligned since ebInterface 5.0, so a business capable of either is positioned for whatever a future domestic B2B mandate brings.
Unlike most of this tracker, Austria doesn't force a single national format — a business already capable of Peppol for other EU markets needs no additional format work for Austrian B2G, and the same applies in reverse for an ebInterface-only implementation.
The USP registration step is specific to government suppliers — a business only trading B2B voluntarily today has no registry to join at all.
Because both accepted formats are EN 16931-aligned, the underlying data requirements are identical regardless of which one a supplier chooses.
B2G submission runs through the USP (Unternehmensserviceportal) — either a direct web upload in ebInterface format, or via the Peppol network — with a legacy EDIAKT II channel still available for large suppliers with pre-existing EDI connections. There is no domestic clearance or real-time reporting model for B2B, which remains a matter of bilateral agreement between trading partners.
As with the Netherlands, there's no clearance model to describe here for B2B — invoices move directly between trading partners, a deliberate contrast to Belgium, France, Italy, and Poland.
Businesses should check whether the specific public body they invoice is a federal agency (covered nationally since 2014/2018) or falls under one of the Länder's own, separately-adopted rules.
This is the one entry on this page that is genuinely undecided — track the sources page and the tracker board for the BMF's formal proposal once published, since it will determine the scope and timeline of any domestic B2B requirement.
With B2B still voluntary, most businesses' near-term work is about readiness rather than compliance: confirming ebInterface or Peppol capability, watching for the BMF's domestic scope decision, and preparing for the confirmed 2030 EU cross-border floor regardless of what that decision covers.
Check whether your ERP or accounting platform already supports ebInterface (6.0/6.1) or Peppol BIS 3.0 — many mainstream Austrian and EU platforms support at least one natively.
Confirm you're registered via the USP and submitting correctly, and check whether the specific body you invoice is federal (covered since 2014/2018) or falls under a Land's own separately-adopted requirement.
This is the single most consequential open question for Austrian e-invoicing — the formal proposal expected in Q3 2026 will determine the scope and timeline of any domestic B2B mandate.
Even before any domestic mandate lands, every business doing intra-EU B2B trade needs EN 16931 e-invoicing and digital reporting capability from 1 July 2030 — this date is fixed by EU directive, not Austrian discretion.
Due in Q4 2026 with a formal EN 16931 syntax binding — no mandatory migration from 6.0/6.1 has been announced, but it's worth knowing about if you use ebInterface directly rather than Peppol.
There is no domestic B2B penalty regime today because there is no domestic B2B mandate — the closest thing to enforcement is B2G invoice rejection for non-compliant format, plus the approaching EU-law floor that applies regardless of Austria's own timeline.
