The cadastral income: new condition for the social supplement

Posted on 17 October 2023

Do you have a modest household income? You may then be entitled to a social supplement to child benefit. From 1 November 2023, in addition to your socio-professional income (taxable wages and benefits), your cadastral income will also be taken into account to determine your entitlement to the social supplement. Is your cadastral income too high? You are then not entitled to a social supplement.

Cadastral income

What is the cadastral income?

The cadastral income reflects the value of your property assets : the land and/or buildings you own or have usufruct over. For entitlement to a social supplement, we only take into account ordinary buildings. These are buildings such as a house or flat.

What income do we look at?

We look at the household income. This is your income if you live alone with your child(ren). If you live with your partner or a person who is not a relative up to the third degree, we examine both of your incomes.

Family members up to the third degree are: (adoptive) parents, (adoptive) children, (great)grandparents, (great)grandchildren, brothers, sisters, cousins, uncles and aunts.

How is household income checked?

To establish entitlement to a social supplement, we look at the cadastral income on 1 January of the previous year.

If this amount exceeds €2.000,00 (not index-linked), you are not entitled to the social supplement. Is the cadastral income less than €2.000,00? Then we check whether the household’s socio-professional income (taxable wages and benefits) is below the ceilings. If so, you are entitled to a social supplement.

When will the first cadastral income check take place?

From 1 November 2023, we will check the cadastral income of households already receiving a social supplement. If the cadastral income on 1 January 2022 exceeds €2.000,00, we will no longer pay the social supplement.

The first impact of this measure will be noticed from the December 2023 payment (= child benefit for November).

Here’s an example: Sophie lives alone with her two children in Brussels, in a house she bought in May 2021. She has been receiving a social supplement since January 2023. In November 2023, we find that Sophie’s cadastral income for January 2022 is €1,500. Sophie continues to receive the social supplement.

What happens for new claims?

For each new child benefit claim, we also examine entitlement to the social supplement. We first check the household’s cadastral income before provisionally granting the social supplement.
We do the same if there is a change in the household composition or a claim for the social supplement.

Here’s an example: In May 2024, Sophie and her children move in with Sophie’s partner Tom. Famiris is informed of this. We then examine whether Sophie is still entitled to the social supplement to child benefit now that she is cohabiting. Next, we check Sophie and Tom’s cadastral income for January 2023. As it turns out, Sophie still has a cadastral income of €1,500. Tom’s cadastral income is €1,800. Together, they have a cadastral income of €3,300. It’s too high. They are no longer entitled to a social supplement. From June 2024, Sophie will no longer receive a social supplement.
