Estimating postdoc salary with "30% ruling" in the Netherlands and is postdoc a "scientific" position? I'm trying to estimate the salary of a postdoc position in the Netherlands. I know that if approved for the "30% ruling," 30% of the gross income is tax-free. But, there are three category in the 30% ruling: (i) Scientific position (for which salary is not a bar); (ii) under 30 with MSc (mainly for the PhDs); and (iii) 'other' category.

I'm using the tool www.thetax.nl to estimate it (I'm not affiliated with it or endorsing it)

Here is the situation:


Gross annual salary (including holiday allowance): 47297
Recruitment: from abroad. She is living (>150kms) 
since forever.
Last degree: PhD (this is a fresh start to a postdoc position).
Age: 30 before starting the position.


My questions are:


If a postdoc gets approved for 30% ruling, then will he/she be considered under scientific position (for which salary is not a bar) or 'other' category of the ruling?
What will be rough monthly salary?
Normally PhDs and Postdocs from abroad would be considered for the 30% ruling, simply increasing your net salary by adding 30% of your gross salary to the net salary. Concerning the salary, normally it would be around 3.1k I have colleagues who are postdocs and their salary is in that range. HR can help you in estimating the net salary and after your friend employee, HR will handle the process of 30% Ruling after being accepted by the municipality.


  Dutch tax legislation provides a special facility for employees attracted from abroad who possess a special expertise that is scarce or cannot be found on the Dutch job market: the 30% ruling. Under this ruling, the employer can provide up to a maximum of 30% of the gross salary to the employee as a tax-free cost allowance`
