New XRechnung version 2.3.1 valid from 1 August 2023
As of August 2023, you should use XRechnung version 2.3.1 to send electronic invoices to all recipients connected to the ZRE and OZG‑RE invoice submission portals.
The previous version 2.2.0 expires on 31 July 2023 and should then no longer be used to submit electronic invoices. E‑invoices should always be sent to recipients using the currently valid version of the XRechnung standard. The new version can be downloaded from the KoSIT website.
