When a child turns 3 years old in Belgium, their parents do not necessarily see a change in their bank account the following month. Family allowances continue to arrive. However, the exact amount depends on the region, the child’s date of birth, and the household composition. Understanding this scale avoids unpleasant surprises, especially when comparing what two neighboring families receive living on either side of a regional border.
Family allowances after 3 years: why the region changes everything
Belgium has regionalized its family allowances. Each region (Wallonia, Brussels-Capital, Flanders, German-speaking Community) sets its own amounts. For a child over 3 years old under the new system, the base amounts differ significantly from one region to another.
Let’s take a concrete example. In 2026, for a child between 0 and 11 years old in the new regime, the monthly base amount is around €196.57 in Wallonia, €190.23 in Brussels, and €184.62 in Flanders. The gap may seem modest each month, but over a full year, it represents a notable difference for a family budget.
Have you moved from one region to another? It is the child’s region of residence that determines the applicable scale. A move from Brussels to Wallonia can therefore change the amount received, even if nothing else has changed in the family situation. To better understand the family allowance scale in Belgium, you must first identify the region to which the child belongs.
Age supplement in Wallonia and Brussels: what increases after 3 years
Beyond the base amount, each region provides age supplements. These are increases that are automatically added when the child reaches certain age milestones. After 3 years, these supplements begin to play a concrete role.
Annual supplements in Wallonia
In Wallonia, children born from 2020 onwards receive an annual age supplement (paid once a year). For the age group of 0 to 4 years inclusive, this supplement is €25.87. It increases to €38.81 for those aged 5-10 years, and then to €64.68 for those aged 11-16 years.
The supplement increases with each age milestone reached. A 4-year-old child therefore receives less than a 6-year-old child, even though their base allowance remains the same until they are 17 years old.
Monthly supplements for children born before 2020
For children born before the Walloon reform (before January 1, 2020), the system is different. Monthly supplements are added starting at age 6. The first child without any other supplement receives €21.59 per month from ages 6 to 11. Subsequent children or those already receiving a social supplement receive €43.06 in the same age group.
Why this distinction? Because two systems still coexist in 2026: the old one (children born before the regional switch date) and the new one. Your 5-year-old child born in 2019 in Wallonia remains in the old system, while their little brother born in 2021 falls under the new scale.
Social supplement and household income: the often-forgotten criterion
The base amount and age supplements are only part of the calculation. Families with modest incomes may be entitled to a social supplement that sometimes doubles the gap between households.
In Brussels, this social supplement depends on the household’s gross income and the number of children. The income thresholds for accessing it tend to be raised regularly, which expands the number of eligible families. The same logic exists in Wallonia and Flanders, but with thresholds and amounts specific to each region.
- In Wallonia, the social supplement is added to the base amount for households whose income does not exceed a certain threshold. It varies according to the child’s rank in the old system.
- In Brussels, the supplement is calculated per child and takes into account the size of the household. Single-parent families often benefit from a higher amount.
- In Flanders, the Groeipakket provides a comparable social supplement, with its own income conditions and amounts.
A household that slightly exceeds the income threshold in a given year may lose this supplement the following year. Checking eligibility for the social supplement each year is necessary.
Disabled child or orphan: specific increases after 3 years
Certain family situations are entitled to increases that are added to the standard scale. This is the case for children recognized with a disability or condition, and for orphans.
For a child with a disability, the increase depends on a point assessment conducted by a doctor. This points system takes into account the impact on daily life, mobility, and necessary care. The higher the number of points, the greater the monthly supplement.
Orphans receive a specific supplement in each region. In Brussels, for example, an orphan supplement is added to the base allowance. In Wallonia, the mechanism is similar but with its own amounts.
- The disability assessment is valid for a limited time. It is necessary to anticipate the renewal of the medical file to avoid an interruption of the supplement.
- The orphan supplement is paid automatically if the family allowance fund is informed of a parent’s death.
- These increases can be combined with the social supplement if the income conditions are met.
Which family allowance fund to choose after regionalization
Since the reform, parents can freely choose their family allowance fund (Famiwal, KidsLife, Camille, Famiris, etc.). The amount paid is the same regardless of the chosen fund, as the scales are set by the region. The difference lies in the service: processing speed, mobile application, personalized support.
A change of fund is possible at any time and does not lead to any interruption of payment. The transfer of the file takes a few weeks. For a family whose child has just turned 3, it is sometimes an opportunity to compare the services offered by different organizations.
The family allowance scale in Belgium after 3 years is not a single figure. It results from a combination of the region, the date of birth, household income, and the child’s particular situation. Keeping an eye on annual indexations and any regional reforms remains the best way to ensure receiving all entitled benefits.
