It's important to note that if you qualify for The Dutch Highly Skilled Visa you will typically also qualify for the great "30% rule" tax exception, this means that you get 30% of your income tax-free for 5 years, and the other 70% will fall mostly in the lowest tax bracket. (Ostensibly to help you move, but in practice really to make The Netherlands more competitive for highly skilled migrants) To qualify you need a salary of €54K (lower if you're under 30), which is pretty easy to get in the tech scene so it's not uncommon for startups in Amsterdam to have all their foreign workers making more than their native Dutch colleagues.
