Tax

What Tax does

TAX (legal name: TAX ABOGADOS ECONOMISTAS) is a Madrid-based professional advisory firm founded in 1990 that delivers integrated tax (fiscal), accounting (contable), labor (laboral), economic, and legal advisory services to businesses and individuals operating in Spain. The firm also targets foreign companies establishing or expanding operations in the Spanish market, with a documented client footprint that spans the EU (UK, Germany, Italy, Portugal, France, Ireland, Belgium) and non-EU jurisdictions (USA, Brazil, Australia, Israel, Russia). Its offering is organized around five advisory pillars plus a specialized branch-creation service for foreign entrants and a supplementary IT/web services line ("Otros Servicios") covering web design, hosting, SEO, IT installation and business computerization.

The firm runs a traditional professional services model: a small, multidisciplinary team of approximately ten economists, lawyers, auditors, risk managers and consultants delivers bespoke engagements from a single headquarters at C/Velázquez 59 in central Madrid. There is no proprietary software platform or disclosed technology stack — value is generated through human expertise and reinforced by an ISO 9001 quality certification (signaled via the "TAX-CALIDAD" brand). An active bilingual blog covering fiscal, labor, legal and accounting topics, plus internal SEO capabilities, supports top-of-funnel demand generation, while a reciprocal partnership with Italian firm StudioBC extends reach into Spain-Italy cross-border mandates.

Revenue is generated through professional fees under quote-based, multi-year contracts with no standardized public pricing; go-to-market is sales-led and direct, relying on inbound contact (web form, phone, email), referral networks, and the StudioBC partnership for cross-border work. TAX is privately held with no external investors, parent company, or subsidiaries disclosed, and the ownership structure appears to be a professional partnership led by Executive Director Antonio García.
