Every January, employees working in companies covered by the Joint Industrial Committee 200 (JIC 200) receive an automatic salary adjustment to reflect the rising cost of living. This annual update—known as wage indexation 2026—ensures that wages keep pace with inflation in Belgium.

How the Belgian Indexation System Works
Belgium’s salary indexation mechanism links wages to the evolution of the flattened health index. Each year, monthly salaries are increased by a percentage equal to the previous year’s inflation rate. This system protects employees’ purchasing power by ensuring their income evolves alongside the cost of living.
Joint Industrial Committee 200 represents the Auxiliary Joint Industrial Committee for white‑collar workers. All employers and employees falling under JIC 200 must apply the same indexation rules, guaranteeing a uniform adjustment across the sector.
Wage Indexation 2026: Final Percentage Announced
- Wage Indexation 2024: 1,48%
- Wage Indexation 2025: 3,58%
- Wage Indexation 2026: As of 1 January 2026, gross salaries for employees under JIC 200 will increase by 2,21%.
This adjustment ensures that employees maintain their purchasing power despite ongoing inflation.
Impact on the Annual Premium
The indexation also affects the annual premium paid in June. If the premium is not replaced by an equivalent benefit, it will amount to € 330,84. This premium forms an important part of the total compensation package and provides additional financial stability for employees.
What This Means in Practice
From January 2026, employees will see a clear increase in their gross salaries. Combined with the annual premium paid in June, this helps ensure that overall compensation remains fair, competitive, and aligned with living costs.
Employers are legally required to apply wage indexation. It cannot be waived—not even with employee consent. Failure to apply the indexation may result in criminal sanctions.
