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.

Did you know Kate can also help you with your security deposit?

Ask your question

Why go for a security deposit account at KBC?

If you’re planning to rent a house or flat, the KBC 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 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 Security Deposit Savings Account, but instead can open a standard savings account in your branch as third-party collateral.

The KBC 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 Mobile or KBC Touch. That could come in handy if your landlord only wants to give you the keys after arranging the security deposit.

Features of a KBC Security Deposit Savings Account

  • Interest earned
    • Current rates: 0.35% base rate of interest and 0.25% fidelity bonus. 

These gross rates are expressed on an annual basis and may change at any time. Current rates are always given here or can be obtained from your KBC branch. If rates change, we will inform account holders of this by post or 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first calendar day following the transaction date, and cease to earn interest from the calendar day on which they are withdrawn.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.

  • Tax efficient
    Individuals are exempt from withholding tax (currently 15%) on the first 980 euros of interest earned each year (2023 figure).
  • Free of charge
    There are no charges for opening and managing the account.
  • Open-ended
    The KBC 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.
  • Risks

    • 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’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 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 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 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 Mobile or KBC 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. More information on property insurance.
