Deadline: update your bank account number before the 5^th day of the month when the tax refund is scheduled. Example: if your notice of assessment states that the tax refund will be made on August 30, then you must update your bank account number by August 5 to receive the tax refund on the chosen bank account.

Important: if you are married or in a legal cohabitation, we will transfer your tax refund to the last known bank account number. This is the same bank account number mentioned in your notice of assessment.

You do not have access to MyMinFin? There are two possibilities:

• Paper form attached to your notice of assessment: if you have received your notice of assessment without a bank account number, fill out and sign the attached form, include your bank account number (IBAN) and the tax item number. Then upload the filed form via our online contact form.
• Online contact form: in case you have not received the paper form, you can also submit your banking details directly through our online contact form. Note: attach a copy of your proof of identity as well as your signature. Note that the contact form is not available in English.

Deadline: submit your form before the 5^th day of the month when the tax refund takes place.

If necessary, you can send us your banking details by postal mail. Note: the processing of these banking data, send through postal service, will take longer and is less secure.

In this case, there are two possibilities:

• Paper form attached to your notice of assessment: if you have received your notice of assessment without a bank account number, fill out and sign the attached form and send it to the following address:
