The system of social security in the Netherlands is one of the most comprehensive ones in the EU. There is an EC agreement which enables you to get urgent medical treatment free in the Netherlands.
When you start working in the Netherlands, you will automatically contribute to the Dutch social security system and consequently be entitled to the same benefits as anywhere else in the EEA.
Most social security contributions are automatically deducted from your salary. These general social security contributions form part of even the lowest income tax bracket. In addition to these contributions, certain social security premiums on employment income (werknemersverzekeringen) are payable by both employers and employees.
