LawTax

What LawTax does

LawTax is a Belgian law firm association (legal entity: Law Tax, Watelet & Associés sprl, BCE 0.556.705.962) founded in 1993 and operating from offices in Brussels (Avenue de Tervueren 128) and Wavre (Chaussée de Namur 79). The firm provides advisory and litigation services in Belgian and international tax law (direct taxes, VAT, registration and inheritance rights), business law (contracts, M&A, judicial reorganization, bankruptcy), financial criminal defense, intellectual property strategy with specialized copyright taxation, and estate and inheritance planning. Client segments include high-net-worth individuals, SMEs, large enterprises, and non-profit organizations. As of January 2025, LawTax integrated with Andersen to operate as Andersen in Belgium, extending its reach into a global advisory network operating across nine languages.

The firm is structured around four equity partners — Thierry Litannie (specialist in tax law, practitioner since 1993), Sébastien Watelet (IP taxation, partner since 2007), Gabriel Rifflart (joined 2011), and Ludovic Hubert (joined 2014) — supported by associate lawyers including Jean-Benoit Capelle and Lisa Delinte. The firm charges hourly fees of EUR 150 to EUR 300 (EUR 350 for urgent interventions), with a 20% overhead pass-through and outcome-based success fees of 10% (under EUR 100,000) or 5% (above EUR 100,000) on disputed sums. Operations run on Kleos practice management software from Wolters Kluwer, certified to ISO 27001, with all lawyer email communications encrypted. The firm previously operated as Litannie, Haulotte, Watelet & Associés.

Distribution and demand generation rely on professional referrals (Belgian Order of Accountants O.E.C.C.B.B., Brussels and Brabant Wallon Bars), content marketing through a multilingual blog covering Belgian tax developments, and public speaking at fiscal conferences such as Fiscalité Day at Ferme Mont-Saint-Jean and BVA-ABA events. The firm also maintains IR Global network membership and partner-level teaching positions at Belgian universities, reinforcing its profile as a thought leader in Belgian tax practice.

Scale indicators1 record

Recent moves6 records

Expansion highlights4 records

Direct peers

• Tiberghien: Belgian tax boutique law firm headquartered in Brussels with a deep specialist practice in direct tax, VAT, estate planning and tax litigation. Closely comparable to LawTax in scale, geography and practice mix, and serves as the most frequently cited peer for high-end Belgian tax mandates.
• AFS Tax Lawyers: Belgian boutique tax law firm operating in Brussels with a specialist tax litigation and advisory practice. Closely comparable to LawTax in scale, customer base (corporates and HNW) and tax-court focus.
• Claeys & Engels: Belgian employment and tax law boutique headquartered in Brussels. Comparable to LawTax in boutique scale, Belgian focus and tax advisory / litigation service mix, particularly for SME and individual clients.

Broad incumbents

• NautaDutilh: Benelux law firm with a Brussels office providing corporate tax, financial regulation and dispute resolution services. Comparable to LawTax on the corporate and HNW advisory axis, though materially larger and broader in scope.
• Loyens & Loeff: Benelux-headquartered full-service law and tax firm with a strong Belgian practice covering corporate tax, M&A and transfer pricing. Significantly larger than LawTax but competes for the same cross-border corporate and HNW tax work that LawTax now targets via Andersen.
• Bird & Bird: International law firm with a strong Brussels presence in IP, technology and tax. Comparable to LawTax on the intersection of IP strategy and tax planning (Watelet's niche), though broader in scope and scale.
• Stibbe: Amsterdam-rooted Benelux law firm with a sizeable Brussels office covering corporate tax, financial criminal law and M&A. A broader incumbent than LawTax but overlaps materially on Belgian tax advisory and litigation mandates.
• Deloitte Legal (Belgium): Big 4-affiliated legal practice in Belgium covering corporate tax, M&A and international tax planning. Competes with LawTax for large-enterprise tax mandates and cross-border structuring work.

Others

• IR Global: International network of professional services firms in which LawTax is a BENELUX member. Functions as a referral and channel partner rather than a competitor, but materially shapes LawTax's inbound cross-border deal flow.

Emerging players

• Andersen Global: International network of member firms providing tax, legal and advisory services, of which LawTax became the Belgian member in January 2025. Comparable as LawTax's new channel partner for cross-border mandates; not a competitor for Belgian-domestic work.
