Answers to your questions about the Netherlands

In most cases no, because the Netherlands has tax treaties with a large number of countries precisely to divide taxing rights and prevent double taxation. Which country may tax what depends on where you are resident, where the company is effectively managed and what kind of income it is: profit, salary or dividend each follow their own rule. The risk is not usually the treaty itself but the assumption that moving here automatically ends your obligations at home. We look at both sides with you, and where your own country is involved we work together with an adviser there rather than guess.
