Managing Partner Tax & Legal

Annelies is Managing Partner of Tax & Legal for Deloitte Belgium and a member of the Deloitte Belgium Executive Committee. 

In this role, she seamlessly merges strategic vision with operational excellence, serving as a valued member of both the Deloitte Belgium Executive Committee and the EMEA Executive Leadership.

Her main mission: to build a bright future for the Belgian Deloitte firm and the Tax & Legal Practice. This includes a people-first approach, establishing Deloitte as the destination of choice for exceptional talent. To achieve this, she cultivates an environment where growth is not merely encouraged but embedded in every interaction, enabling her teams to deliver transformative, differentiated solutions to our clients.

This solution-oriented approach is combined with a relentless focus to drive value for clients. To bring this to life, she takes on a global LTLP role and remains the client partner in several major files.

Since becoming Partner in 2015, Annelies established herself as a trusted architect of tax transformation. She guides multinational enterprises to reimagine how tax and legal functions operate, building a competitive advantage rather than merely fulfilling compliance obligations.
