Beigel Steuerberater PartG

What Beigel Steuerberater PartG does

Beigel Steuerberater PartG mbB is a third-generation, family-owned tax advisory and legal services firm headquartered in Starnberg, Bavaria, in the Fünfseenland (Five Lakes Region) south of Munich. Founded in the 1960s by Theo Beigel, the firm claims to be the oldest still-active tax advisory practice in the region. It serves three core client segments: small and medium enterprises (GmbHs and growing businesses), private individuals (employees, self-employed, property owners, retirees), and nonprofit associations and foundations. Services span corporate and personal tax compliance, ongoing bookkeeping and payroll, annual financial statements, tax return preparation, audit (Wirtschaftsprüfung), business succession advisory, and in-house legal counsel covering corporate, inheritance, and contract law.

The firm is structured as a PartG mbB partnership with four partners—Bernhard Beigel (Steuerberater, Rechtsanwalt, Wirtschaftsprüfer), Thomas Beigel (Steuerberater), Christoph Beigel (Steuerberater, Rechtsanwalt; Fachberater für Unternehmensnachfolge, joined the firm in early 2023), and Birgit Rudolph (Steuerberaterin, with the firm since 1986)—plus a dedicated digitalization lead (Florian Beigel) and approximately 25 total staff. Differentiated delivery rests on multi-qualified partners offering tax, legal, and audit services under one roof, combined with a fully digitalized operating model built on the ADDISON OneClick platform (Wolters Kluwer), including a secure client portal, mobile receipt-scanning apps, and paperless document exchange. The firm has held the official 'Digitale Steuerkanzlei' (Digital Tax Advisory Firm) certification for over five consecutive years and received a kununu Top Company 2026 employer-recognition badge.

The business model is a fee-based professional services model billed under the German Steuerberatervergütungsverordnung (StBVV) or individual fee agreements, with revenue from ongoing retainer mandates and per-engagement advisory work. Go-to-market is sales-led and relationship-driven, anchored on personal consultations, local SEO, content marketing (Steuertipps blog and "Beigel Update" newsletter), LinkedIn/Instagram presence, and word-of-mouth referrals. The firm operates a single office in Starnberg with services delivered in-person or via the digital client portal, and targets the Starnberg/Fünfseenland/Bavaria market exclusively. Revenue, pricing, and ARR figures are not publicly disclosed.

Others

• Haufe Group: German tax, legal, and HR publishing and software provider offering tax tips, digital tools, and compliance content. Adjacent — Beigel publishes similar Steuertipps content and competes for the same tax-information-seeking audience.
• DATEV eG: German cooperative providing tax software, digital workflows, and member services to Steuerberater firms. Indirect peer — Beigel operates on DATEV/ADDISON infrastructure, and DATEV sits at the center of the same tax-advisory ecosystem.

Broad incumbents

• RSM GmbH: German member of RSM International providing audit, tax, and consulting to mid-market companies. Broad incumbent competing for the same Mittelstand succession-planning and advisory mandates as Beigel.
• BDO AG Wirtschaftsprüfungsgesellschaft: German arm of BDO Global, offering audit, tax, and advisory services with broad industry coverage. Broad incumbent that competes for mid-market German tax and audit mandates above Beigel's typical size band.
• Mazars GmbH & Co. KG: German operation of Mazars offering audit, tax, and advisory with strong Mittelstand focus. Broad incumbent providing integrated tax+legal+audit at a scale Beigel cannot match.
• PKF Fasselt: German member of PKF International providing audit, tax, and advisory services to mid-market clients. Comparable integrated offering in the same Mittelstand segment Beigel serves.

Direct peers

• Rödl & Partner: German mid-tier professional services firm combining tax, legal, and audit services under one roof with strong Mittelstand and family-business focus. Direct peer to Beigel's integrated tax+legal+audit offering and similar succession-planning expertise.

Regional players

• Lohnsteuerhilfe Bayern e.V. Bavarian tax-help association focused on private individuals' income tax returns. Regional competitor for Beigel's private-client tax preparation segment, though operating under a help-association model rather than full Steuerberater services.
