Ivonne van Duren (1974) has been employed at Bol Adviseurs since 2002. She has specialised in cross-border employee traffic. This is why Ivonne works at the Netherlands-Germany Desk and the Netherlands-Belgium Desk. Her work consists of advice on cross-border employment (taxation and social law), the 30% ruling, salary split and construction permits and regulation both in Germany and Belgium. Ivonne attempts to exclude the client’s chance of fines and investigations and to show the client around the maze of the international rules of the game. Ivonne sees the variation in her work, especially the language, as a challenge.
