Announcement to our existing members:
The previous fidelity premium remains fixed and will continue to apply to all previously made deposits remaining on the account for twelve months, up until twelve months after the date of the deposit. In other words, the adjustment of the fidelity premium does not affect previous deposits for up to twelve months.

What do our Savings Accounts offer?

  • Receive a fidelity premium for deposits on your account for longer than 1 year and a base rate on other deposits.
  • Choose what works for you: Extended with a higher fidelity premium or Standard with a higher base rate.
  • And exempt from 15% withholding tax on the first €980 of interest earned in 2023.

Type of product

All of our Regulated Savings Accounts are free of charge and are opened for an indefinite duration. Your  money is always available without any costs. Account is for mobile clients only. 

Our regulated savings accounts Extended and Max Deposit Extended offer a 0.50% base rate and a 1.50% fidelity premium. Our regulated savings account Standard and Max Deposit Standard offer a 1.00% base rate with a 0.50% fidelity premium. 

The base interest is acquired as from the day after the money is deposited on the account and until the day of  withdrawal. The fidelity premium is only acquired on the amounts which have stayed uninterruptedly on the  regulated savings account for 12 months following the deposit. The rate of the fidelity premium in force at the  time of the deposit or the start of a new acquisition period remains unchanged for a period of 12 months. 

The rates on our savings accounts can be changed at any given time. Our members will be notified of such  changes via email. 

All of our Regulated Savings Accounts are subject to Belgian law and complying with the conditions set out in  Article 2 of the Royal Decree executing the Income Tax Code 1992. 

Before opening an account, please read the key information for savers and the deposit guarantee information  sheet above.
