What Tax Master Gestión does

Tax Master Gestión, S.L. (TMG) is a privately held Spanish advisory firm specializing in fiscal, labor, and accounting services for SMEs, self-employed professionals (autónomos), individuals, patrimonial companies, foundations/associations, and real estate holding entities. Founded in 2008 and headquartered in Oviedo, the firm operates as a subsidiary of Lener Grupo Asesor, S.L., a diversified advisory conglomerate headquartered in Madrid. The company delivers its services through six physical offices distributed across Spain (Oviedo, Madrid, Barcelona, Valladolid, Vigo, Sevilla) and a client portal (Área Clientes) hosted at taxmastergestion.bilky.es.

The firm's service portfolio spans seven core modules: Laboral (payroll, HR administration, labor compliance), Fiscal Empresas (corporate tax), Fiscal Autónomos (self-employed tax), Fiscal Personas Físicas (individual tax), Fiscal Fundaciones/ONG's (non-profit tax), Consultoría económica-financiera (economic-financial consulting), and Gestión de carteras inmobiliarias (real estate portfolio management for financial entities, family offices, and investment funds). The firm emphasizes a multidisciplinary team approach with horizontal coordination across fiscal, labor, and accounting practices. It does not develop proprietary technology products; its technology footprint consists of the client portal and certified information security management under ISO/IEC 27001 and the Spanish National Security Framework (ENS, RD 311/2022).

The business model is professional services fee-based with non-public pricing and a sales-led go-to-market approach that includes free initial consultations. Customer acquisition channels are primarily the corporate website (taxmastergestion.es), phone, email, and a newsletter. The firm targets a vertical segmentation across six client types rather than concentrating on a single segment. With a disclosed headcount of 9 employees and no public financial reporting, the firm operates as a small boutique within the larger Lener Group ecosystem.
