HSP GRUPPE

HSP GRUPPE is a German tax consulting group whose member firms operate under the shared brand HSP STEUER. According to its official website, the practices within the HSP GRUPPE network position themselves as innovation drivers in the tax advisory industry, combining high technical and professional competence with individual, personal client care. The network presents itself as modern and digitalisation-friendly, aiming to understand each client's business model and advise them in a forward-looking manner. The group's core activity is tax advisory and related professional services for businesses, freelancers and private clients. Its service portfolio spans the typical life-cycle stages of a company — from foundation and start-up support through ongoing operations to succession and restructuring — and includes both advisory and compliance/declaration work. Specific services listed on the official website include choice of legal form and incorporation support, investment and financing advice, subsidy and funding advice, rating support and bank meeting accompaniment, contract design and contract management, optimisation of invoicing and payroll processes, analyses and research, expert opinions, IT support and software provision, as well as annual financial statements, tax returns and tax registrations, payroll accounting (classic or fully digital) and financial accounting (classic or fully digital). The network is organised as a federation of independent local tax advisory offices (Kanzleien) that share the HSP STEUER brand and infrastructure. The official website provides a location search by federal state or postal code area and lists around 96 HSP locations across Germany. The distribution shown on the homepage includes, for example, 14 locations in Bavaria, 14 in Lower Saxony, 14 in North Rhine-Westphalia, 12 in Hesse, 6 in Baden-Württemberg, 6 in Saxony-Anhalt, 6 in Schleswig-Holstein, 5 in Hamburg, 4 in Rhineland-Palatinate, 3 in Berlin, 3 in Mecklenburg-Vorpommern, 2 in Brandenburg, 2 in Bremen, 2 in Saxony, 2 in Thuringia and 1 in Saarland. Individual member firms carry names such as HSP STEUER Huget & Kornack Partnerschaft Steuerberater in Ahrensburg or HSP STEUER 3 S Steuerberatungsgesellschaft mbH in Alsfeld. HSP GRUPPE has also attracted attention for its use of artificial intelligence in tax practice. In August 2026, OpenAI published a success story about the HSP GRUPPE, describing how ChatGPT Enterprise is used in its offices. According to the group's own report on that publication, survey results from the shared ChatGPT Enterprise workspace of HSP GRUPPE and Kanzleipakt showed that 98.6% of respondents reported higher productivity, 84.6% saw improved work quality, and 95.9% said they saved time each week. The group calculated roughly 40,000 additional hours of capacity per year in a conservative scenario, of which an estimated 28,000 hours were productive specialist work and 12,000 hours administration, client service and support. The group also reported that 79.7% experienced better client service and 78.1% reported higher job satisfaction. As a privately held professional services network, HSP GRUPPE does not appear to be listed on a stock exchange. Its public identity is built around the HSP STEUER brand, which serves as the umbrella for its member tax advisory firms across Germany.
