Founded in 1939, the firm has built a multi-decade authority in Belgian and Luxembourg taxation, anchored by the annual Tiberghien Tax Law Manual (Handboek voor Fiscaal Recht) published since 1955 and the recurring Key Figures in Belgian Estate and Income Tax reference. The firm is consistently recognized as an EMEA Top Tier tax practice by Legal 500 and is a recurring author of Chambers and Partners International Tax and Succession & Estate Planning guides for Belgium and Luxembourg. It is a core member of the WTS Global network and operates Tiberghien Economics as a wholly-owned subsidiary providing adjacent tax economics and economic consulting services.

The firm's core offering is bespoke tax and legal advisory services for two primary segments: businesses and corporations requiring Belgian and Luxembourg tax advisory, cross-border structuring, M&A tax support, DAC 6 reporting, anti-money laundering compliance, and EU customs matters; and high-net-worth individuals requiring estate planning, cross-border pension planning, international succession, and real estate tax advice across Belgium, France, Spain, Italy, and other jurisdictions. Pricing is professional-services based, with hourly rates ranging from EUR 170 to EUR 465 depending on lawyer experience, billed monthly, with the option of success fees in certain matters. Go-to-market is partner-led enterprise field sales combined with thought-leadership marketing through publications, webinars, newsletters, and LinkedIn/X/Instagram presence under the @tiberghientax handle. No proprietary technology, API, SDK, or AI tooling is part of the offering; the firm is a pure-play human-advisory practice with 101–250 employees and no publicly disclosed revenue.
