OZG application portal for the chambers of tax consultants

Oct. 01, 2020 to Sep. 30, 2023

An application portal has been developed as part of the Online Access Act to provide members of the chambers of tax consultants with simple application and communication processes. Our scientific team provided specialist and technical support for the project.


Task and problem definition

The Online Access Act intends to digitise key services for the more than 100,000 members of the chambers of tax consultants. The objective is the creation of a portal that bundles the administrative services of the regional chambers of tax consultants in a standardised application portal and provides members with a central point of entry for communication with their chambers. This should remove the need to search for regional contact points for tax consultants or the need to communicate by fax.


Solution approach and technical implementation

The OZG project was implemented in just 14 months under the leadership of the Nuremberg and Munich Chambers of Tax Consultants in collaboration with the software developer mgm. During the preparatory phase, our scientific team advised on the technical structure of the OZG application portal to be tendered. With the aim of creating a future-proof, serviceable system, we provided professional and technical support for the realisation of the project.

Our services in the project:

  • Drafting the performance specification of the system
  • Planning of the system
  • Consultancy and support during the tendering process for the system
  • Advice on the planned system architecture
  • Professional and technical support during implementation.

A central challenge of the project was the harmonisation of the chamber-specific applications and the transfer to user-friendly online forms. This process was accelerated by a clear division of tasks and the application of mgm's enterprise low-code platform A12. From a technical perspective, the portal is based on a microservice architecture and runs in a Kubernetes cluster. The federal user account (BundID) is connected for user authentication. The chambers fully implement the service catalogue according to the OZG with the portal.
