If you are registered in a municipality in the Netherlands, you obtain a Citizen Service Number (Burger Service Nummer – BSN). A citizen service number is a unique number for anyone in respect of matters related to the Dutch government authorities. The BSN will facilitate any interaction with the Dutch authorities: starting a job, opening a bank account, deducting your taxes and social security contributions, using the healthcare system, applying for possible benefits, announcing a change of address, etc. By having a citizen service number, the Dutch government authorities also intend to improve service to you, to combat fraud and to provide more protection off your privacy. If your stay as a foreign employee exceeds a 4 month period, you must register within your municipality.
When you start working for Boskalis, the Relocation Company will assist you to obtain your BSN.
