PME Assistance/DCA/DTAX

What PME Assistance/DCA/DTAX does

PME Assistance/DCA/DTAX (operating under the Belux Accounting brand) is a Brussels-based boutique advisory practice founded in 2005 that delivers integrated tax, audit, accounting, and corporate-structuring services to entrepreneurs, private families, SMEs, and independent professionals across Belgium and Luxembourg. The firm operates through three coordinated sub-brands: DCA-S handles strategic tax and legal advisory including corporate structuring, statutory and special audits, due diligence, business valuations, and reorganizations; PME Assistance provides operational accounting, periodic close, statutory accounts, VAT compliance, and management reporting for SMEs; and DTAX.LU delivers Luxembourg-side cross-border structuring including SOPARFI/SPF design, governance, substance, and Belgium–Luxembourg residency and tax coordination. The team's technology stack consists of standard Belgian and Luxembourg accounting platforms — FID-Manager, Wolters Kluwer, Exact/Winbooks, and Horus — with no proprietary software, API surface, or AI components disclosed.

The firm operates a referral-only go-to-market with no paid marketing or digital advertising; 500+ client relationships have been built almost entirely through word-of-mouth from entrepreneurs and families served. Engagement is senior-led and by appointment, with all inquiries reviewed under statutory professional secrecy; the firm holds ITAA membership in Belgium and OEC membership in Luxembourg. The team of 20+ experts collectively brings over 180 years of combined experience, and revenue is generated through professional service fees across advisory engagements and recurring compliance work. In January 2026, PME Assistance/DCA/DTAX was acquired by PIA Group — an international accountancy, advisory, and audit network headquartered in Ghent — as part of a five-firm BeLux expansion that added 193 employees and €27.7 million in revenue to PIA Group's €440 million consolidated turnover across 52 brands and 92 offices.
