Letters from Belastingdienst

Action: register your bank account with the Dutch tax authorities


If you received this letterm the Dutch tax authorities do not have your bank account details for a tax refund that is waiting for you. They remind you because they have informed you with respect to the missing bank account number already.

If you can login into your portal at belastingdienst.nl with Digid and you have an iban account number, you can register the bank account details easily online. If not, you are required to file a letter with the Dutch tax authorities.
