The Ministry of Finance published an updated overview of the qualification foreign social security systems.

This overview is applicable for people who are working in the Netherlands but who remain social secured in their home state. The employer has to check whether a social security contribution can be deducted from the Dutch taxable income or that a contribution which is paid by the employer might be taxable. Since every country has their own social security system, it is hard to compare the foreign and Dutch system. Therefore the Dutch Ministry published an overview. In this overview they inform per country which contribution can be deducted or needs to be added to the taxable income. We recommend to check if the foreign social contributions are correctly processed in the payroll.
