Munich, October 1, 2026 – WTS, an international full-service provider of tax consulting and complementary financial advisory services, is expanding its transfer pricing practice in southern Germany. Effective October 1, 2026, Maren Holtz will join WTS as a partner at the Stuttgart office, coming from EY. The tax advisor and certified public accountant has many years of experience in international transfer pricing consulting.
Maren Holtz has been a partner in the International Tax and Transaction Services / Transfer Pricing practice at EY in Stuttgart since 2017. Her consulting focus is on the international transfer pricing structuring of value chains, restructuring, and transfer pricing defense. Previously, she worked for EY in Düsseldorf and spent four years in New York. In New York, she established an international transfer pricing team as part of the implementation of the OECD BEPS initiative and advised U.S. corporations in particular on European developments.
Before joining EY, Maren Holtz worked at a regional accounting firm and at PwC. There, she advised large German family-owned businesses, among others, and worked in international tax law and auditing.
At WTS, Maren Holtz will support internationally active companies, particularly in the transformation of their value chains and transfer pricing functions. In addition, she will help further advance cross-border collaboration in the area of transfer pricing within the international WTS network, WTS Global.
“With Maren Holtz, we are gaining a partner with an outstanding professional network and extensive international consulting experience. She will strengthen our presence in the economically significant Stuttgart region and provide important impetus for the further development of our transfer pricing practice,” says Florian Gimmler, Head of Transfer Pricing Germany at WTS.
“WTS combines in-depth tax advisory services with a consistent focus on technology, digitalization, and artificial intelligence. This environment offers ideal conditions for developing innovative advisory services and actively shaping the transformation of tax departments together with our clients. I look forward to contributing my expertise here,” explains Maren Holtz.
WTS’s transfer pricing practice is one of the strongest in the market and continues to grow: As early as the middle of this year, two experienced partners—Prof. Dr. Stephan Rasch and Marion Leherpeur—joined the firm. With Maren Holtz, the practice now has its first female transfer pricing partner at the Stuttgart office.
