Our partners

T/A international

The starting point of our international services is T/A international, an operational Benelux cooperation between Tiberghien Belgium, Tiberghien Luxembourg, Atlas Tax Lawyers in the Netherlands and the economic consulting firm, T/A economics. T/A International serves as a platform for over 100 tax professionals in 3 jurisdictions. Also, outside the Benelux, Tiberghien has its office in Zurich.

T/A economics is a Transfer Pricing consultancy firm covering the whole of the Benelux. It offers tailored expertise to corporations in the field of transfer pricing, valuations, business modelling and legal economics (economic analyses supporting legal issues). T/A economics and Tiberghien share their expertise and combine tax legal with economic insights. 

Atlas Tax Lawyers is an independent tax consultancy firm located in the center of Amsterdam and in Eindhoven. The company is especially well-known for its in-depth knowledge in the areas of private equity, M&A, real estate, financial services, tax structuring and private client matters.



ALTIUS is an independent full-service Belgian law firm with an international focus. From its offices in Brussels and Louvain-la-Neuve, it advises Belgian and international corporations about the legal aspects of their transactions and disputes.

Tiberghien often joins forces with ALTIUS for client cases that not merely require tax legal advice, but also demand expertise in the field of corporation law. However, this partnership is not exclusive and does not impede collaboration with other legal teams if required for our clients. 



WTS Global is a global network of carefully selected consultancy firms specialising in tax law. Worldwide, this network consists of partners from over 100 countries and they offer a full range of services. This unique alliance creates clear added-value for cross-border related tax-legal issues.
