For Authorities

The Lower Saxony Civil and Business Service (BUS) contains more than 1400 descriptions of administrative services provided by the Lower Saxony authorities as well as of cross-border public administration services from A such as demolition notice to Z, such as second home tax.

The BUS is part of the implementation of the Federal Information Management and the information requirements arising from various legal regulations, such as the European Services Directive, the Professional Qualifications Directive, the Single Digital Gateway Regulation. SDG Ordinance), the Online Access Act (OZG) and the Lower Saxony Law on Digital Administration and Information Security (NDIG).

The contents of the BUS are supervised by the state editorial board on behalf of the Lower Saxony Ministry of Home Affairs and Sport, which receives texts about the catalogue of services of the Federal government and the Länder (LeiKa) or produces content based on state law requirements and as required by the authorities in cooperation with departments and municipalities. The information structure supports the XÖV standard XZUFI.

In the BUS, it is possible to capture and present a complete vertical representation of responsibilities across all levels of administration. All levels of administration are included in the collection and maintenance of the data: the specialist departments in the state ministries draw up legally secure service descriptions, based on state law or in extension of federal law, which are supplemented at the level of local government by regional and municipal specialities for implementation and provided with the actually competent authorities. For example, it is possible to map municipal statutes and forms. The registration of the competent authorities directly by the local administrations ensures correct statements about responsibility, especially in the division of tasks between the municipality and the district.

Content set in the BUS can be obtained via interfaces and used for own official internet portals. They shall also be made available for information in the case of the authorities number 115.

All authorities within the scope of the NDIG must publish general information about their authority in the BUS (Section 5 (1) NDIG). From 1.07.2021, detailed information on the individual administrative bars must also be published in the BUS (Section 5 (2) NDIG). Administrative services must be available in the BUS as early as 12.12.2020 in accordance with Article 4 of the SDG Regulation.

More than 400 municipalities and many state authorities are already connected to the BUS. A monthly newsletter provides you with information about changes in the service portfolio in order to be able to react promptly to updates.
