Groll, Gross & Steiner

What Groll, Gross & Steiner does

Groll, Gross & Steiner is a Munich-based law and tax advisory partnership established in 1983, operating from a single office at Prannerstraße 6 in central Munich. The firm specializes in inheritance law (Erbrecht) and tax advisory, delivering integrated legal and tax counsel to private individuals, small and mid-sized enterprises (Mittelstand), and self-employed professionals (Freie Berufe). Three of its attorneys — Dr. Anton Steiner, Matthias Rösler, and Paul Grötsch — hold the Fachanwalt für Erbrecht (Specialist Attorney for Inheritance Law) qualification, a formally regulated credential in German law. Tax advisory is delivered by licensed Steuerberater Alfons Schuster and Iris Ntanelis, supported by additional attorneys including Dr. Annalisa Bogner and Florentin Staudacher.

The firm's service portfolio centers on testament drafting, Pflichtteil (forced heirship) claims, estate administration and executorship, business succession planning, gift and inheritance tax structuring, and general tax compliance (financial statements, tax returns, payroll). As a founding member of the Deutsches Forum für Erbrecht e.V., the firm maintains referral relationships that enable international cross-border inheritance matters. Digital client service delivery is supported through third-party platforms: DATEV Meine Steuern and DATEV Unternehmen Online for tax document and accounting workflows, FP Sign for eIDAS-compliant electronic signatures, and WebAkte for encrypted client communication. The firm also publishes a Pflichtteilsrechner (forced share calculator) as a digital client tool.

The business model is a traditional professional services partnership with statutory fee schedules (RVG for legal services, StBVV for tax advisory) as the primary pricing mechanism, supplemented by individual fee agreements for appropriate matters. GTM is sales-led through partner reputation, professional network referrals, and sustained third-party award recognition (WirtschaftsWoche, FOCUS-SPEZIAL, Capital). The firm is privately held with no external investment, parent entity, or subsidiaries. With 8 employees, the partnership operates as a boutique specialist practice rather than a scaling platform.

Core offering

Groll, Gross & Steiner provides integrated legal and tax advisory from a single Munich office, specializing in inheritance law (Erbrecht) including testament drafting, Pflichtteil (forced heirship) claims, estate administration, succession planning, and gift/inheritance tax planning. The firm also delivers tax advisory (Steuerberatung) covering annual financial statements, tax return filing, financial and payroll accounting, and tax compliance for individuals, mid-market businesses, and self-employed professionals. Service delivery is supported by third-party digital platforms for document handling, secure client communication, and legally binding electronic signatures.

Product overview

Groll, Gross & Steiner is a Munich-based law and tax advisory firm established in 1983, operating as a unified professional services practice with two core offerings: Erbrecht (inheritance law legal advisory) and Steuerberatung (tax consulting). The firm delivers legal and tax advice from a single source, combining specialized inheritance law expertise with comprehensive tax advisory services. The core Erbrecht practice encompasses testament drafting, forced heirship (Pflichtteil) claims, estate administration, gift planning, and court representation. The Steuerberatung practice covers financial statements, tax returns, accounting, and payroll services. Digital service delivery is supported through integrated third-party platforms including DATEV Meine Steuern (client tax document management), DATEV Unternehmen Online (accounting and document exchange), FP Sign (electronic signatures), and WebAkte (secure document portal). The firm holds no product-level certifications or API offerings, as it is a traditional professional services firm rather than a software product company.
