AMSTERDAM, October 7, 2026 – Global professional services firm Alvarez & Marsal (A&M) has scaled up its Netherlands Tax practice with the addition of Managing Director Monica Erasmus-Koen and her full team from Taxtimbre, joining at the start of October. The move meets growing client demand for tax advice, data and implementation.
The incoming team will deepen the global transfer pricing platform led by Dan Peters. Ms. Erasmus-Koen and her team bring credibility, market trust and a reputation combining transfer pricing advisory expertise with hands-on tax-technology implementation experience.
Marc Sanders, Netherlands Country Lead for A&M Tax, explained: ‘Most tax teams spend their time reconstructing the past – pulling together data, checking it, and explaining how a number was reached. Technology can make that faster and more reliable, but the bigger opportunity lies in integrating technical transfer pricing expertise with technology.
‘From initial design, through to ongoing operation, we can help clients build data and processes that are consistent, well-governed and easy to trace back to source – providing a stronger, audit-ready foundation. Once tax data is properly connected, it can be used to model what could happen next, not just report on what’s already happened.’
Ms. Erasmus-Koen will spearhead the transfer pricing capability build-out in the Netherlands, advising multinational organizations on matters spanning the design and implementation of transfer pricing via cloud-based software platform, data collection, local-file production, operational transfer pricing and post-go-live support.
She brings more than 25 years of tax consulting experience, having served as a Taxtimbre partner for more than eight years and previously holding senior roles at Tytho, PwC and EY. She has lectured on transfer pricing at the International Bureau of Fiscal Documentation (IBFD) since 2010.
Marvin Rust, Head of A&M Tax EMEA, said: ‘Monica and her team are a strong fit as we further build the business. Their proven track record in technology-enabled transfer pricing complements our independent, results-oriented, transformation-focused model, and creates a more robust platform for delivering on Dutch-led mandates.’
Ernesto ‘Ernie’ Perez, Global Head of A&M Tax, added: ‘The Netherlands is a major cross-border business hub, home to a sophisticated multinational client base, and an essential piece of A&M Tax’s growth. Since its launch in 2021, our Dutch practice has grown steadily, further enabling our teams to deliver seamless, high-quality advice to clients across markets. We are excited about the opportunities adding this talent set will bring.’
