Is salary a good reason to move to the Netherlands?

Yes and no. In the Netherlands, rich and poor are not far apart, we are a very social country. The tax scales are progressive, so the more you earn, the higher the percentage of income tax you have to pay. As an expat in the Netherlands you can use the 30% scheme, where the last 30% of the income can be paid untaxed. This saves €600.00 net per month! That makes your salary a lot higher than that of a Dutch colleague. And your income is likely to be above average. You can find more information about the 30% scheme on the website of the Tax Office: https://www.belastingdienst.nl/wps/wcm/connect/bldcontenten/belastingdienst/individuals/living_and_working/working_in_another_country_temporarily/you_are_coming_to_work_in_the_netherlands/30_facility_for_incoming_employees/.
