What KSB INTAX does

KSB INTAX is a German interdisciplinary professional services firm headquartered in Hannover with branch offices in Celle and Lüneburg, operating as a Partnerschaftsgesellschaft mit beschränkter Berufshaftung (PartGmbB). The firm delivers an integrated suite of legal advisory, tax consulting, statutory and voluntary auditing, and notary services, supplemented by specialized practice areas including M&A, restructuring, company succession, family office, employment law, IT/IP, real estate, and insolvency. Service delivery combines generalist coordination with specialist depth across its 18+ named partners and approximately 60+ qualified advisors, organized under German professional regulatory frameworks (BRAO, StBerG, WPO, BNotO).

The business model is fee-for-service professional engagement, billed primarily on time invested with fees determined by qualification level under statutory schedules (RVG, StBVV, GNotKG). The firm is sales-led, relying on direct client engagement, partner-led referrals, and a content-marketing program comprising a regulatory blog, monthly tax newsletter, and podcast. Go-to-market is concentrated on the German Mittelstand (mid-market companies), family-owned enterprises, and startups/venture-backed companies. Four wholly-owned subsidiaries extend the practice into adjacent verticals: KSB INTAX Treuhand GmbH (auditing and tax), KSB INTAX Projekt GmbH (real estate and project management), KSB INTAX Datenschutz GmbH (data protection), and KSB INTAX Versicherungsschadenmanagement GmbH (claims management).

KSB INTAX has accumulated sustained regional recognition, winning Juve Awards 2024 as Law Firm of the Year for both the German Mid-Market and Northern Germany, and being listed in Handelsblatt's Best Law Firms in Germany 2025. The firm operates exclusively within Germany with no international footprint, serves no disclosed named enterprise or logo customer set, and does not publish financial figures. Its competitive position rests on regulatory credential density, partner-level specialization, and an interdisciplinary service model that addresses the coordination cost German mid-sized clients face when engaging separate legal, tax, and audit advisors.
