IKTKonG — the first continental EU national B2G mandate after Denmark

The IKT-Konsolidierungsgesetz (Federal IT Consolidation Act), published in Federal Law Gazette BGBl I 2013/175, has made e-invoicing mandatory for all suppliers to the Austrian federal administration since 1 January 2014. It is the second national B2G mandate in the European Union (Denmark came first in 2005) and the first among continental civil-law states.

History — why 2014?

Austria did not wait for Directive 2014/55/EU. When the EU adopted its public procurement and e-invoicing directive at the end of 2014, the IKTKonG had already been in force for almost a year. Timeline:

2013-07  IKT-Konsolidierungsgesetz package adopted by Nationalrat
2013-10  Publication BGBl I 2013/175 (Federal Law Gazette)
2013-11  BMF decree — technical modalities (USP + ebInterface)
2014-01-01  Entry into force — federal B2G mandate
2014-Q2  ~50,000 federal suppliers migrated to USP
2018     USP <-> PEPPOL AP interconnection (cross-border access)
2019     EN 16931 conformance (Directive 2014/55/EU) — Bund + Länder
2024     ebInterface 6.1 update (EN 16931 + ViDA alignment)

• 2010-2013 budget context. The financial crisis pushed the Austrian federal state to seek savings. The IKT-Konsolidierung programme (IT consolidation) aimed to pool datacenters, business applications and administrative flows across ministries.
• e-Rechnung component. BMF (Finance Ministry) had been piloting USP since 2008 — a single business portal for VAT (FinanzOnline), social security (DataNET) and international trade. Mandating ebInterface for paper-replacement invoicing fit naturally into this centralisation logic.
• Danish precedent. Denmark had mandated B2G e-invoicing as early as 2005 via NemHandel. Austria drew inspiration from the Danish model but retained a national XML format (ebInterface) rather than OIOUBL.
• Implementing decree. The BMF e-Rechnungs-Verordnung, published late 2013, specified technical modalities: USP transport, accepted formats, Buchungskreis service code for routing.

Scope — who is concerned

• All federal administrations (Bund): ministries (BMF, BMI, BMVIT, BMK, etc.), federal agencies, public universities, BIG (Bundesimmobiliengesellschaft, federal real estate manager), ÖBB (Federal Railways for sovereign activities), AMA (Agrarmarkt Austria), AGES, ASFINAG (motorways).
• All suppliers: domestic and foreign, legal entities and individuals. No minimum threshold — an invoice of €50 must be in ebInterface or PEPPOL.
• Outside Bund: the nine Länder (Vienna, Lower Austria, Upper Austria, Salzburg, Tyrol, Vorarlberg, Carinthia, Styria, Burgenland) and 2,000+ Gemeinden (municipalities) set their own policy. Most have joined PEPPOL via USP, but the obligation remains federal law.
• EU public procurement: since 18 April 2019 (Directive 2014/55/EU), all Austrian public authorities must accept an EN 16931 invoice, even if they don't mandate it. Austrian practice goes further: a federal issuance mandate has been in force since 2014.

Legal basis — BGBl I 2013/175 and related texts

Accepted formats — ebInterface and PEPPOL

BMF accepts two EN 16931-conformant XML syntaxes:

• ebInterface: Austrian national format maintained by AUSTRIAPRO since 2003. Versions 4.x to 6.1. Schemas published on austria.pro/ebinterface. It is the default format for the USP portal.
• PEPPOL BIS Billing 3.0: European UBL standard profile. Accepted by USP since 2018, transits via the Austrian federal AP 0192: (gov.at PEPPOL ID).
• Austria-specific metadata. The element OrderReferenceDetail (ebInterface) or BT-13 (UBL) must carry the Auftragsreferenz = federal entity purchase order number (Bestellnummer). Without it, HV-SAP routing fails and the invoice is rejected.
• Attachment. ebInterface allows a human-readable PDF to be embedded (Anhang base64). It is a frequent local usage to reproduce the original commercial document.

USP — federal single channel

The Unternehmensserviceportal portal (usp.gv.at) is the single federal B2G issuance channel:

• 3 submission modes: (a) manual web capture for very small issuers, (b) XML upload for ERPs that batch-export, (c) SOAP/REST web service for real-time ERP integration.
• Authentication: via FinanzOnline (tax ID), Bürgerkarte (digital ID card) or Handy-Signatur (official mobile signature).
• Acknowledgment: each accepted invoice receives an e-Rechnung-ID (10 digits). Status can be checked online or via web service.
• Lead time: ~24-48 h to payment processing (Verbuchung) in HV-SAP, ~30 net days for effective settlement under the BHG federal budget law.

Penalties — payment refusal, no fiscal fine

Unlike RTIRs (Italy, Hungary, Romania), IKTKonG is not a fiscal obligation. It is a contractual obligation of federal public procurement:

• Payment refusal. A paper invoice received by a federal entity is rejected — the supplier must reissue via USP. No fine, but the payment clock starts only from the conformant invoice.
• No criminal penalty. IKTKonG does not provide for administrative fines. The lever is purely economic: no e-invoice → no payment.
• Practical consequence. Recurring suppliers migrated already in 2014. One-off suppliers usually go through the free, fast USP web capture.

Common pitfalls

• Confusing Bund and Länder. The IKTKonG mandate only covers the federal administration. Vienna (Magistrat), Lower Austria, Vorarlberg, etc., have their own rules (often PEPPOL-aligned, but not automatic).
• Forgetting the Buchungskreis. Without this 4-char identifier, HV-SAP cannot allocate the expense to the right budget line. The invoice is rejected.
• Believing PEPPOL bypasses USP. The Austrian federal PEPPOL access point mandatorily transits via USP. No direct AP-to-AP path for Bund entities.
• Underestimating the accounting dimension. A technically compliant invoice without a valid Bestellnummer reference is rejected for lack of commitment (Mittelbindungsvoraussetzung).
• Confusing IKTKonG with a B2B mandate. Austria has no domestic B2B mandate. EU ViDA will drive that topic, see the BMF roadmap.
