E-invoicing in Austria

B2G mandatoryPeppol connectedUpdated January 2026Verified · automated check

Austria was an early B2G adopter (mandatory since 2014) with its own ebInterface national standard alongside Peppol. B2B e-invoicing is voluntary but widely adopted. A mandatory B2B mandate is expected under EU ViDA, likely between 2027 and 2028.

TL;DR

Austria requires (B2G) e-invoicing using ebinterface, peppol_bis formats. Connected to the Peppol network for cross-border exchange.

Implementation notes

ebInterface vs Peppol. Austria accepts both ebInterface 6.0 (national standard) and Peppol BIS Billing 3.0 for B2G. The ebInterface format is EN 16931 aligned but has Austrian-specific extensions. If you're building for multiple markets, Peppol BIS 3.0 is the safer choice. B2G invoices are submitted via the USP (Unternehmensserviceportal). Digital signatures are optional but recommended.
