BIC
Please enter the BIC (Bank Identifier Code) of your current bank account.
Tax refunds will always be transferred by the tax office to the bank account which you specify here. If your address or bank account changes before you have received the tax refund, contact the tax office as soon as possible.
Note: If you do not provide any bank account, you can simply leave the fields blank. The tax office does not usually pay out tax refunds in cash. If you do not provide a bank account, the tax office will contact you to ask for your bank details and it will take longer for you to receive your refund on your account. If you do not have a bank account, the tax office will send a crossed cheque to the address you have provided.
