What Contaxus does

Contaxus B.V. is a privately held Dutch professional services firm operating as a tax advisory and accounting practice (belastingadviseurs & accountants) targeting growth-oriented entrepreneurs in the Netherlands. The firm delivers three integrated service lines: (1) Advies (Tax Advisory) covering VAT and transfer tax, international taxation, estate planning, objection and appeal procedures, restructuring, DGA (director-major shareholder) practice, compliance, and general business advice; (2) Accountancy (Accounting) providing annual accounts preparation, administration, and dashboards with forecasting; and (3) Salarisadministratie (Payroll Administration) for client payroll processing. Delivery is advisor-led and quote-based, with professional engagements structured around client complexity rather than standardized pricing.

The firm operates from two Netherlands locations — Volendam (Julianaweg 192-F) and Schiphol-Rijk (Beechavenue 124, near Amsterdam Schiphol Airport) — the latter positioned to support internationally active Dutch entrepreneurs. Service credibility is anchored by professional affiliations with NBA (Royal Netherlands Institute of Chartered Accountants), VFM (Dutch tax professionals association), and REP (Register Estate Planners). Lead advisor Niels Scholten, a former Deloitte tax practitioner (1999–2010), holds REP registration and provides specialized DGA, estate planning, and restructuring expertise. A basic digital client portal ("Mijn Contaxus") supports document handling, but the firm has no proprietary technology platform and no disclosed AI/ML capabilities.

Contaxus monetizes through professional fee engagements billed by scope and complexity, with no publicly disclosed pricing. Its go-to-market is sales-led and relationship-driven, supplemented by content marketing through an active Dutch-language blog covering tax jurisprudence and regulatory updates. No headcount, revenue, funding, or ownership structure is publicly disclosed; the firm appears to operate as an independent partnership-style practice serving the Dutch SMB-to-mid-market entrepreneur segment.
