BBZ - You are working in the Netherlands temporarily

If you will be working in the Netherlands temporarily for your Belgian employer, you can easily arrange to stay covered under the Belgian social insurance system. However, medical expenses will be reimbursed by the Netherlands.

Arranging your social insurance

If you will be working in the Netherlands temporarily, you should arrange your social insurance as follows: 

• Apply, through your employer, for an E101 form from the Rijksdienst voor Sociale Zekerheid in Brussels: (0032)2 509 31 11. With this form, you can show that you are covered under Belgian social insurance and that you do not have to pay contributions in the Netherlands.
• You should then request a European Health Insurance Card (EHIC) from your health insurer. With this card, you can get reimbursement for medical care in the Netherlands.

Tax

If you are in the Netherlands for more than 183 days to work, you will start paying tax in the Netherlands as from the day you start working in the Netherlands.
