Bundessteuerberaterkammer KdöR

What Bundessteuerberaterkammer KdöR does

The Bundessteuerberaterkammer KdöR (BStBK) is a Körperschaft des öffentlichen Rechts (public law corporation) operating since 1961 as the federally designated statutory umbrella organization for tax advisors in Germany under § 86 of the Steuerberatungsgesetz. Its core function is to coordinate the 17 regional Steuerberaterkammern across Germany's 16 federal states and to represent approximately 105,953 registered tax advisors and tax advisory companies (as of January 2026) in legislative, regulatory, and international fora. The organization is led by President Prof. Dr. Hartmut Schwab, Vice President Volker Kaiser, and a three-person executive team of Managing Directors (Dr. Moritz Alt, Claudia Kalina-Kerschbaum, and Bettina Bethge) supported by approximately 30 staff at its Berlin headquarters on Wallstraße.

BStBK's technology footprint centers on a suite of interconnected digital platforms. The Vollmachtsdatenbank (VDB) is the electronic power-of-attorney database that was comprehensively rebuilt in June 2026 with a new user interface. The beSt (besonderes elektronisches Steuerpostfach) is the secure electronic mailbox for tax-advisor-to-tax-authority communication within the EGVP framework. The Steuerberaterplattform unifies access to beSt, VDB, and identity services, including planned integration with the EU Digital Identity Wallet (EUDI-Wallet). The organization also maintains the Amtliches Steuerberaterverzeichnis and two additional statutory directories, plus publishes the annual Berufsstatistik. Document management is supported by a DocuWare cloud instance, and the organization operates in compliance with GDPR/BDSG via an external data protection officer.

As a non-profit professional chamber, BStBK is funded entirely through membership fees routed via the 17 regional chambers; it does not sell commercial products or services and discloses no revenue. Its go-to-market is non-commercial: services are delivered to members through mandatory chamber membership and digital self-service platforms. Strategic activity in 2026 has emphasized platform modernization (VDB rebuild), regulatory advocacy (multiple Stellungnahmen on AMLA, EU Business Wallet, Jahressteuergesetz, DSFinVBV), defense of the Fremdbesitzverbot to block financial-investor entry, and thought-leadership initiatives (TaxTech Role Models with TAXPUNK, AI/GoBD/e-invoicing FAQ catalogs, Fachkräfteinitiative with DATEV and DStV).

Scale indicators5 records

Recent moves7 records

Expansion highlights5 records

Regional players

• AICPA: American Institute of CPAs, the largest US professional body for accountants with ~400,000+ members. Comparable in scale and scope of services (standards, advocacy, continuing education), but operating under US state-board regulation rather than a single federal chamber model.
• ICAEW: UK chartered accountants body regulating ~200,000 members worldwide. Comparable in mandate (licensing, standards, member services) and digital infrastructure (e.g., ICAEW regulatory platform), but serves a different jurisdiction.

Direct peers

• Deutscher Steuerberaterverband (DStV): Voluntary professional association for tax advisors in Germany — parallel to BStBK but focused on advocacy and member services rather than statutory regulation. BStBK actively partners with DStV on the Fachkräfteinitiative.
• Bundesrechtsanwaltskammer (BRAK): Federal chamber for lawyers in Germany under § 176 BRAO. Mirrors BStBK's statutory structure, regional coordination role, and digital infrastructure mandate (e.g., beA electronic mailbox for attorneys is the closest analogue to beSt).
• Wirtschaftsprüferkammer (WPK): Statutory federal chamber for auditors in Germany under § 57 WPO, structurally identical to BStBK: enforces professional standards, runs official directories, and coordinates regional chambers. Most directly comparable peer given parallel mandate in an adjacent regulated profession.
• Bundesnotarkammer (BNotK): Federal chamber for notaries under § 76 BNotO. Operates as a Körperschaft des öffentlichen Rechts with parallel structure to BStBK: statutory mandate, regional chambers, official directory, and professional standards enforcement.
• Bundesärztekammer (BÄK): Federal chamber for physicians in Germany under § 13 Bundesärzteordnung. Provides a directly comparable model of a statutory professional self-governing body coordinating 17 state chambers, running registries, and representing the profession in legislative processes.

Others

• DATEV eG: Germany's leading IT and software cooperative serving tax advisors, auditors, and lawyers. BStBK's named strategic partner on the Fachkräfteinitiative; ecosystem participant rather than direct competitor, but a critical enabler of BStBK's digital mandate.
• Institut der Wirtschaftsprüfer in Deutschland e.V. (IDW): Professional institute for German auditors, parallel to DStV but for the audit profession. Provides standards, publications, and advocacy that complement the statutory role of WPK — analogous to DStV's relationship with BStBK.
