What is a security deposit?

A security deposit is an amount that you, as the tenant, usually pay into a blocked account at the beginning of your lease. If you comply with all the obligations in your lease, you’ll get your security deposit back when the lease ends.* If the rented property has been damaged, the landlord may use some or all of the deposit to cover the repairs.

Why go for a security deposit account at KBC Brussels?

If you’re planning to rent a house or flat, the KBC Brussels Security Deposit Savings Account is a good idea. Why? Because landlords usually require a security deposit. By putting this on a blocked savings account, neither you nor the landlord can touch it for the duration of the lease.

You can also open aKBC Brussels Security Deposit Savings Account when renting student accommodation, a service flat, a room in a nursing home or a parking space. In other situations (e.g., commercial leases), you can't use a KBC Brussels Security Deposit Savings Account, but instead can open a standard savings account in your branch as third-party collateral.

The KBC Brussels Security Deposit Savings Account is a regulated savings account offered by KBC Bank NV, Belgium. It is governed by the laws of Belgium.

Start using your security deposit account right away

You don’t need to be with us to open a security deposit account, but you do need a Belgian ID card. Simply open the account through our website to start using it right away and we’ll e-mail your landlord to confirm everything if you like.

Bank with us and you can quickly open the account in KBC Brussels Mobile or KBC Brussels Touch. That could come in handy if your landlord only wants to give you the keys after arranging the security deposit.

Security deposit account earnings

Current rates

Base rate of interest 0.45%
Fidelity bonus 0.45%

The rates shown are gross and annualised and can change at any time. Current rates are always shown above or can be obtained from your KBC Brussels branch. If the rates change, we will inform you by post or through one of our digital channels.

Savings earn interest at the base rate from the very first calendar day following the transaction date, and cease to earn interest from the calendar day on which they are withdrawn.

The fidelity bonus is awarded for amounts that remain on the savings account for 12 full, consecutive months. If money is withdrawn or transferred from the account, the accruing fidelity bonuses whose acquisition date is furthest in the future will be the first to be ended. However, for the first three transfers per year to another regulated savings account held with KBC Brussels, there is a pro rata transfer of the fidelity bonus, provided the following conditions are met:

  • The two savings accounts have at least one holder who is the same person.
  • Each transfer is for at least 500 euros.
  • The funds are not transferred by standing order or automatic savings order.

This means that the current 12-month calculation period is not interrupted but continues running on the beneficiary savings account. Therefore, the fidelity bonus is likewise only awarded on amounts that are held, in this case, on two or more savings accounts for 12 consecutive months.

Features of a KBC Brussels Security Deposit Savings Account

  • Tax efficient
    Individuals are exempt from withholding tax (currently 15%) on the first 1,020 euros of interest earned each year (2024 figure).
  • Free of charge
    There are no charges for opening and managing the account.
  • Open-ended
    The KBC Brussels Security Deposit Savings Account is an open-ended product. The security deposit agreement linked to this account remains in force until the security deposit savings account is closed.


  • Insolvency risk: a maximum of 100,000 euros of your aggregate deposits with KBC Bank are guaranteed per person, subject to certain conditions. In the event of KBC Brussels’s insolvency (e.g., if it goes into bankruptcy), you run the risk of losing any deposits you have over 100,000 euros, or their amount could be reduced or converted into shares. You can obtain a copy of our ‘Protection of deposits and financial instruments in Belgium’ brochure from your KBC Brussels branch or from

  • Inflation risk: this savings account also has an inflation risk, as sustained price increases can result in the amount deposited losing value.

Releasing funds on a security deposit

You open a KBC Brussels Security Deposit Savings Account when the lease starts and the deposit is released at the end of the lease by:

  • written agreement between the tenants and the landlord (or joint landlords)
  • court order (small claims court)

You no longer have to go to a KBC Brussels branch to ask for the deposit to be released. Instead, you can do it easily in our app by scanning or taking a photo of the completed and signed release document, the lease and the landlord's ID card (or copies of each landlord's card if the property is jointly owned) and forwarding them to us in KBC Brussels Mobile or KBC Brussels Touch. If everything is in order, we return the amount of the security deposit (plus interest), ensuring it is divided up as agreed.

Besides arranging your security deposit, remember to take out tenant property insurance too

Tenants in Flanders and Wallonia must have property insurance (i.e. home insurance) if the rented property is their main residence. Read the Insurance Information Document carefully before taking out this insurance. More information on property insurance.
