S·K· Steuerberater, Wirtschaftsprüfer, Rechtsanwälte

What S·K· Steuerberater, Wirtschaftsprüfer, Rechtsanwälte does

S·K· Steuerberater, Wirtschaftsprüfer, Rechtsanwälte is a privately held German multidisciplinary professional services firm founded in 1983 by Prof. Dr. K. Schwantag and Dr. P. Kraushaar, operating through two legal entities: Prof. Dr. K. Schwantag · Dr. P. Kraushaar Steuerberatungs GbR (Dresden) and Prof. Dr. K. Schwantag · Dr. P. Kraushaar GmbH Wirtschaftsprüfungsgesellschaft (Frankfurt am Main, HRB 22905). The firm delivers integrated tax advisory (Steuerberatung), statutory and voluntary auditing (Wirtschaftsprüfung), legal advisory (Rechtsanwälte) primarily in tax law, plus accounting, payroll, succession planning, exit taxation, international tax, and nonprofit/foundation advisory. It employs approximately 46 staff — 6 licensed Berufsträger holding Steuerberater, Wirtschaftsprüfer, and/or Rechtsanwalt credentials, plus around 40 specialized employees — across two offices in Frankfurt am Main and Dresden, with active Managing Partners at each site (Lothar Boelsen, Anne Rinkenberger, and Jana Seifert).

The business model is engagement-based professional services billing, with quote-priced mandates tailored to client complexity and no published rate cards. Customer segments are diversified across medium-sized companies, family-owned enterprises (a primary focus), non-profits and foundations, healthcare professionals, freelancers, real estate investors, HNW individuals, and internationally active companies. International mandates are delivered primarily through the firm's membership in the Leading Edge Alliance, providing access to 600+ member offices across 110+ countries, supplemented by referral partnerships with Voigt Salus, Dezan Shira & Associates, Bol International, and Hübner & Hübner. Go-to-market is sales-led and relationship-driven, supported by content marketing (tax tips, downloadable guides), SEO, email newsletters (Sendinblue), social media presence (LinkedIn, XING, Instagram, Facebook), and a sustained earned-media presence via annual TOP-Tax Consultant and best-auditor rankings across FOCUS-MONEY, Handelsblatt, WirtschaftsWoche, and manager magazin.

There is no proprietary technology platform; the firm operates as a traditional advisory practice using commodity tools — DATEV for German tax/accounting software compliance, Google Analytics and Google Maps on its website, and Sendinblue for newsletter distribution. The firm's competitive position rests on its multidisciplinary credential stack, regulatory licenses (Wirtschaftsprüferkammer, Steuerberaterkammer), 40+ year operating history, and consistent third-party ranking recognition rather than on technology differentiation.
