How can I update my tax information?

Modified on Thu, 26 Jun at 3:51 PM

You can update your tax information quickly and easily via the Aion Bank mobile app. Please follow the steps below:

  1. Log in to the Aion Bank mobile app

  2. Go to Profile (bottom right corner)

  3. Tap Settings

  4. Select Personal

  5. Choose the Tax Information section to review and update your details.


If you are not a Belgian tax resident, please contact us via the in-app chat or by email at info@aion.be to request and complete the tax exemption form. This form is required to ensure that the interest earned on your account is not subject to Belgian taxation.


The tax exemption form for individuals who are not Belgian tax residents must be duly signed and submitted on an annual basis.
