Schomerus & Partner

What Schomerus & Partner does

Schomerus & Partner is a German multidisciplinary professional services firm headquartered in Hamburg, founded in 1924 as Hamburger Treuhand. The firm delivers tax advisory (Steuerberatung), legal advisory (Rechtsberatung), auditing (Wirtschaftsprüfung), and IT/data protection compliance services to four specialized client segments: mid-sized companies (Mittelstand) including German subsidiaries of international firms, demanding private clients and high-net-worth individuals, tax-privileged nonprofit organizations (NPOs), and social-economy enterprises. Approximately 190 employees operate across five German offices (Hamburg, Berlin, Munich, Stralsund, Paderborn), with international reach through the HLB International network.

The firm's service portfolio spans core professional services — statutory and voluntary audits (including Konzernabschlussprüfungen and §57a WPO peer-reviewed quality control), tax compliance and representation, and legal counsel across corporate, employment, real estate, IT, and nonprofit law — alongside newer capability lines in digital transformation, IT law, data protection, and KI-Compliance delivered through its Technologiewerft Compliance GmbH subsidiary. The vereinfacher.de portal extends a digital self-service channel for NPO association management. Several partners are recognized in Handelsblatt/Best Lawyers rankings (Corporate/M&A, Employment Law, Tax Law), and the firm has been consecutively named a Manager Magazin Top Auditing Firm from 2019 to 2023.

The business model is engagement-based professional services billing, with fees negotiated per mandate based on scope and complexity, typically under multi-year retainers. Revenue streams derive from tax advisory, legal advisory, audit services, and ancillary compliance/digital services. The firm is structured as a Partnerschaft mit beschränkter Berufshaftung (mbB) — a German professional partnership with limited liability — with wholly-owned operating subsidiaries including Hamburger Treuhand Gesellschaft Schomerus & Partner mbB Wirtschaftsprüfungsgesellschaft (auditing), Schomerus Compliance GmbH, Technologiewerft Compliance GmbH, and Schomerus Service GmbH. Go-to-market relies on direct advisory mandates, long-standing client relationships, referrals, industry-specific thought leadership, and the HLB network rather than marketing-led acquisition.
