Munich, 17 August 2026 – WTS, an international full-service provider of tax advisory and complementary financial advisory services, continues to drive forward its expansion agenda, welcoming two high-profile additions at partner level: Prof. Dr. Stephan Rasch and Marion Leherpeur. Both join from PwC and will further build out WTS's structuring-oriented transfer pricing advisory practice.
Prof. Dr. Stephan Rasch has been strengthening the transfer pricing practice at WTS since August. With this move from PwC, WTS gains one of the best-known transfer pricing experts in Germany. Together with a larger team, he will further develop the TP Service Line and sharpen WTS's positioning in the high-end segment.
Prof. Dr. Stephan Rasch specializes in the design and implementation of transfer pricing systems for multinational companies. In addition, he defends clients in tax audits, negotiates Advance Pricing Agreements, conducts mutual agreement procedures, and represents clients before the fiscal courts. He is an honorary professor at the Institute for Business and Tax Law at the University of Augsburg and a lecturer at the University of Liechtenstein. His profile is further rounded out by an Executive MBA and a certification from the Global Board Academy for supervisory and advisory board members.
Alongside his tax and academic work, Stephan Rasch is intensively engaged with the use of AI in the advisory environment, combining tax expertise with technology competence. He has built this expertise through AI programs at MIT and Imperial College London, as well as through studies in machine learning at the University of Texas at Austin, further strengthening WTS's AI- and technology-centered advisory approach.
Marion Leherpeur has already been on board at WTS as a new transfer pricing partner since July. She brings more than 18 years of experience advising large multinational companies on transfer pricing. A particular focus of her work is supporting clients through tax audits, advance pricing procedures, and mutual agreement procedures. She also has extensive experience in restructuring and planning projects, particularly in connection with function relocations and the conversion of transfer pricing systems. Marion Leherpeur is distinguished by particular expertise in economic analysis. She additionally gained valuable in-house experience as head of transfer pricing at an S-DAX listed group.
Alongside the expansion of AI and digitalization solutions, structuring-oriented advisory is one of the key growth areas in WTS's service portfolio. With the arrival of Prof. Dr. Stephan Rasch and Marion Leherpeur, this strategic direction is being consistently pursued. WTS's TP practice thereby underscores its position as one of the market-leading full-service units for transfer pricing advisory in Germany.
