Mark van Casteren (1966)
Mark van Casteren received his degree in tax law from the Universiteit van Amsterdam in 1990. In 1990, he worked, studied, and lived in Atlanta, Georgia as an international summer associate for Arnall Golden & Gregory and studied US Taxation at Emory. After having served his country as a conscripted officer in the First Dutch Army Corps, he backpacked through Southeast Asia.
In 1992, Mark started as a tax advisor with (then tax law firm) Loyens & Volkmaars, which merged with the general law practice of Loeff Claeys Verbeke, to become Loyens & Loeff N.V., where he was made partner in 2001. Mark headed the firm’s New York office until 2005, advising US multi-nationals on financial transactions and corporate structuring. After his return to the Amsterdam offices, he built up the private equity platform practice for US based private equity firms and also advised a wide range of Canadian corporates and pension funds about their investments in or through the Netherlands.
Mark is frequently recognised as Tier 1 tax advisor by Legal 500 and was recommended by Who-is-who Legal 2021 in the categories Corporate Tax Advisory and Foreign Investment Review.
Mark was the primary contact of Loyens & Loeff with the ruling team of the Dutch tax authorities.
In 2015, Mark changed his focus to transfer pricing and, together with his current Huygens partners, developed a quantitative approach of tax consultancy.
Mark frequently speaks on international tax topics during international seminars and has lectured transfer pricing courses for the Nederlandse Orde van Belastingadviseurs (NOB). He was a member of the board of directors of the American Chambers of Commerce from 2019 to 2021.
Next to his work, Mark loves running (although he is not a fast runner), playing tennis and spending time with his family (wife, four – grownup – kids and his Weimaraner dog).
