Mein Unternehmenskonto
The extended mailbox

To enable companies nationwide to process applications simply, quickly and without media discontinuity, the federal government has decided to create a standardized Unternehmenskonto as part of the implementation of the Online Access Act (OZG). This is intended to facilitate access to digital administrative services via a central platform for contact with public authorities.

In its circular resolution of February 14, 2020, the IT Planning Council instructed the states of Bremen and Bavaria to roll out the uniform Unternehmenskonto they had designed for all the states. The Unternehmenskonto consists of a building block principle;

  • Bavaria is creating the technical and practical prerequisites for implementation on an ELSTER basis (modules 1-4);
  • Bremen designs the components of an extended functional mailbox and authorization as independently usable convenience functions in the Unternehmenskonto in coordination with Bavaria (modules 5-6).

Based on the ELSTER technology from Bavaria, which is already established in the tax sector, a central online portal will be offered in the future with the uniform Unternehmenskonto - Mein Unternehmenskonto (Mein.UK).

In addition to the already existing and well-known "ELSTER mailbox", Bremen contributes an extended mailbox as well as the necessary authorization mechanisms.

Both functionalities were requested in particular by representatives and associations from the business community. Bremen relies on the expertise of its IT service providers and has commissioned Dataport with the implementation of the authorization module and Governikus with the implementation of the extended Unternehmenskonto (working title OZG-PLUS-Postfach). This includes the modules for business and government (MuWiSta), which consist of modules 5 + 6 of the unified Unternehmenskonto. The extended company mailbox will also enable companies to participate in electronic legal transactions - i.e., communication with the judiciary.

Both the corporate mailbox and the authorization module developed by Dataport are scheduled to go live nationwide in 2023.

Convenient and legally binding communication with authorities and the judiciary for companies

The unified Unternehmenskonto is designed to facilitate access to administrative services, in line with the OZG. Companies can easily set up and configure their extended company mailbox with their ELSTER organization certificate.

The MuWiSta - modules 5 and 6 provide solutions for written form substitution communication for organizations. The "module 5" developed by us - the so-called OZG-PLUS-Postfach - offers extended mailbox functionalities in Unternehmenskonto.

With MuWiSta - Module 5, we are therefore pursuing two overarching goals:

  1. A service that standardizes communication between administration and organizations. In this context, unification means the similar way of accessing and sending messages and not the unification of the respective infrastructures.
  2. Creating a bridge between the respective infrastructures and at the same time a unified approach so that further domain-specific approaches become unnecessary.

Functionalities of MuWiSta - Module 5

The corporate mailbox enables communication with a wide range of administrative departments and bundles them in an end-to-end encrypted web application for structured data transfer.

  • The communication can be initially triggered by companies (application) as well as by the administration. Depending on the scenario, messages or notifications received can be responded to via the company mailbox.
  • The company mailbox enables legally binding delivery.
  • Functional mailboxes as well as group mailboxes are supported, and substitute rules can also be set up.
  • Infrastructures, such as the EGVP system for electronic legal transactions, are integrated via the company mailbox. This means that companies can communicate with the judiciary, among others, via the company mailbox in addition to communicating with public authorities using eBO (electronic citizens' and organizations' mailbox).
  • Companies can easily set up and configure their extended corporate mailbox with their ELSTER organization certificate.

Answers to frequently asked questions (FAQ)

Yes, this is regulated in the framework agreement and in OZG 2. However, there is no direct connection between the modules. It therefore has no influence on the functional mailboxes.
Yes, users will be able to use the OZG-PLUS-Postfach and/or the Postfach 2.0, which is implicitly assigned to an organization certificate.
Yes, both mailboxes have their own interface for the pseudonyms and can therefore be distinguished.
This is the case according to the Online Access Act (OZG).
There will be no technical connection to the tax mailbox of ELSTER, just as the environment with the associated mailbox of the Employment Agency will not be connected.
This depends on the tax number of the companies. One Unternehmenskonto is provided for each tax number.
The administrator can add several employees to a mailbox as user:in. These employees can represent each other. The admin is only assigned once and cannot be replaced by a user, because his key data is only assigned once.
The use and the interface should be as identical as possible, so that the users do not experience any distinction between Mein Unternehmenskonto and OZG-PLUS-Postfach.
The function mailbox designations should not be cryptic designations, but human-speakable. This would make it possible to assign them to the functional mailboxes. From the system's point of view, the assignment is made via a certificate directory that shows which functional mailboxes a company has. The correct mailbox can be selected via the appropriate encryption certificate. This requires a connection to the NEZO interface.
Yes, Chambers of Crafts are eligible to purchase products from the Governikus application under the state and federal maintenance agreement. This includes COM Despina, which is required for pilot participation.
The desired mailbox must first be selected by the user when a request is made.

PDF files with a maximum size of 250 MByte are provided. However, an attachment does not necessarily have to be sent with a message.
It stands in iteration 1 the use of an online service as contact. In it, it can be specified whether the communication is to run via a connected "Mein Unternehmenskonto". However, bi-directional communication is in the scope of the OZG-PLUS-Postfach.
