SANTAX

What SANTAX does

SANTAX (legal name SANTAX fiscaal economen) is a Dutch belastingadvieskantoor — a tax advisory and multi-disciplinary professional services firm — operating as a sole proprietorship (eenmanszaak) from Volendam, Netherlands, founded in 2000 by drs. Sander Schilder FM RV. The firm serves Dutch DGA's (director-major shareholders), IB-ondernemers (sole proprietors), and family businesses primarily in the Volendam / Edam-Volendam / North Holland catchment, delivering tax advice, tax return preparation (income, corporate, inheritance/gift, wage, VAT, dividend), annual financial statements, payroll administration, online financial administration, business valuation (BOR / succession-related), online and offline mediation, forensic mediation (court-appointed in family and commercial chambers), and entrepreneurship coaching. A separately operated education sub-brand, Santax Opleidingen, provides practical courses to legal and financial professionals, with the founder also teaching at SRA, SSR, IMFO and CPE.

The technology stack is composed of third-party web-based bookkeeping platforms — Reeleezee, Twinfield, Exact Online, with Unit4, iMuis, Snelstart, and Davilex supported as alternates — combined with a web-based payroll portal that lets employees self-serve payslips and a remote "meekijken" (co-viewing) capability into client administrations. Marketing uses a MailChimp-distributed bimonthly newsletter (Santip) with explicit consent, Google Analytics with IP anonymization for measurement, and an SSL-secured website with Google reCAPTCHA. Content distribution is reinforced by a long-running Nivo column (since April 1998) and vakpublicaties in Dutch fiscal journals (EB, Fiscaal Tijdschrift Vermogen, Weekblad fiscaal recht, TaxLive, etc.).

The business model is professional services: hourly and quote-based fees with no public rate card, supplemented by a gratis intake (free intake) offered to prospects. Pricing is explicitly positioned as "comparable to the Big Four but at a friendlier price," targeting clients who want premium advisory quality at independent-firm rates. GTM is sales-led, driven by the founder's personal brand, the Nivo/Santip content cadence, and the free walk-in consultation hour hosted weekly by Martin Tol. The firm has no external funding, no parent company, no institutional shareholders, and no disclosed revenue; ownership and operational control are concentrated entirely in the founder.

Core offering

SANTAX is a Dutch belastingadvieskantoor (tax advisory firm) that delivers integrated fiscal and accountancy services to entrepreneurs and business owners. Its core offering covers tax advice, tax return preparation, annual financial statements, payroll administration, and online financial administration, complemented by mediation (including forensic mediation), independent business valuation (Valuation), and ondernemerscoaching (entrepreneur coaching). All advisory work is led by founder/owner Sander Schilder and a small specialist team operating from Volendam, Netherlands.

Product overview

SANTAX is a single integrated Dutch professional services firm ("belastingadvieskantoor") rather than a multi-product software platform. The firm's offering is organized around a core set of advisory and compliance service lines: Fiscaal advies (tax advice), Aangifte (tax returns), Jaarrekening (annual financial statements), Loonadministratie (payroll), and Financiële administratie (financial administration) together form the Fiscaal advies & Accountancy pillar delivered against leading web-based boekhoudprogramma's such as Reeleezee, Twinfield, and Exact Online. Alongside this, Ondernemerscoaching, Mediation (also delivered online), Forensische Mediation, and Valuation are offered as complementary advisory lines. The firm operates a separate education sub-brand, Santax Opleidingen, and runs recurring content publications including the Santip newsletter, the Nivo column series (since 1998), and Vakpublicaties in professional journals.

Direct peers

• DRV Accountants & Adviseurs: Dutch mid-market accountancy and advisory group offering tax, accountancy, valuation and business coaching to family businesses and DGAs; comparable to SANTAX in its multi-disciplinary bundle for SME entrepreneurs and in its regional Dutch footprint.
• Flynth: Large Dutch accountancy and advisory cooperative serving agri, SME and family-business clients with tax, accountancy and valuation; relevant peer for SANTAX because of overlapping DGA/IB-ondernemer focus, multi-disciplinary offering and reliance on cloud bookkeeping platforms.
• Accon avm: Mid-market Dutch accountancy and advisory firm serving SMEs and family businesses with tax, accountancy, valuation and advisory services; closely comparable to SANTAX in service mix and target DGA/IB-ondernemer segment, but operating at materially larger scale across multiple Dutch regions.

Broad incumbents

• Grant Thornton Nederland: Mid-tier international advisory network with a Dutch practice focused on mid-market companies; relevant peer because it competes for the same Dutch DGA/SME advisory wallet as SANTAX, at larger scale.
• Mazars Nederland: International accounting and advisory firm with a Dutch practice serving mid-market companies; comparable to SANTAX on the SME tax/accountancy axis but offers a broader, global service portfolio.
• BDO Nederland: Top-tier Dutch mid-market audit, tax and advisory network; competes with SANTAX for the same Dutch DGA and family-business client pool but at materially larger scale and broader service portfolio.
• Baker Tilly Nederland: Dutch mid-tier accounting and advisory network competing for SME and family-business advisory mandates; overlaps with SANTAX on tax, accountancy and valuation but operates as a multi-office network rather than a single regional firm.
• KPMG Meijburg & Co: Dutch tax advisory arm of KPMG serving large DGAs, family businesses and international clients; competes with SANTAX for high-end Dutch tax-advisory work and represents the Big-Four benchmark against which SANTAX positions itself.

Regional players

• Countus: Dutch regional accountancy and advisory firm serving SME entrepreneurs with tax, accountancy and business advice; comparable to SANTAX in target client (Dutch DGA/IB-ondernemer), service mix and regional focus, though it operates in different Dutch provinces.

Emerging players

• Moneybird: Dutch SaaS bookkeeping, invoicing and VAT/tax-filing platform targeting zzp'ers and small SMEs; relevant peer as a structural threat to SANTAX's compliance/accountancy revenue layer, since it enables direct client self-service on the same workflows SANTAX delivers.
