Update on e-Invoicing in the German Federal States


UPDATED 03/31/21: Germany is advancing the implementation of e-invoicing in public administrations according to a timeline that makes B2G invoicing mandatory in the federated states.

Since 18th April 2020 the federated states must accept e-invoices in compliance with the European Directive 2014/55/EU. The status of e-invoicing depends on each Federal State (Bundesland) transposing the European Directive via a local decree-law regulating:

  • Communication systems.
  • Formats.
  • E-invoice reception points with regional and local public authorities.

The federal law on German e-invoicing, E-Rechnungs-Gesetz, allows the federated states power to draft their own transposition decrees.

The federated states can choose whether to follow the model determined by the Core Invoice User Specification (CIUS) or their own e-invoicing standard. They are also free to choose whether they want to use the central government’s Zentrales Rechnungseingangsportal OZG-RE platform or their own systems.

If the Federal States develop their own web service, they must offer a connection through the PEPPOL network.

As a result of the decentralized nature of the German billing system, its establishment has had a different development in each federal state.

ZUGFeRD 2.1 Model

The update of the ZUGFeRD e-invoicing model makes it compatible with European standard EN 16931 and the French standard Factur-X 1.0.

Version 1.0 was developed prior to the adoption of Directive 2014/55/EU of 16th April 2014 and before the publication of EN 16931. This means it does not comply with the standardization requirements approved by the European Committee for Standardization (CEN), and therefore was incompatible.

ZUGFeRD 2.1 published in March 2020 includes corrections to ensure its’ conformity with EN 16931. The new developments include:

  • Updating of the code lists.
  • A solution to upper and lower case problems in the specification identifier.
  • Corrections for individual cardinalities and the assignation of elements to individual profiles.
  • Adjustments to better align ZUGFeRD 2.0 with Factur-X.

Besides the updated ZUGFeRD format, the standard used for e-invoicing in B2G relations is the German PEPPOL UBL format, called XRechnung. This format is mandatory for central, regional, and local authorities.

The ZUGFeRD model is expected to gain traction in relations with public administrations following this update. Until now, ZUGFeRD’s hybrid format, involving an A3 PDF and an XML, was the one most commonly used in the B2B sphere. This was because it facilitated electronic processes for businesses and individuals with a low technological profile.
