Indexation January 2027 in Belgium: every joint committee

What happens on 1 January 2027, per joint committee

Sources for this data: see the list at the bottom.

When is the figure final?

For white-collar staff in PC 200, the average of the smoothed health index of November and December 2026 is divided by the same average for November and December 2025. The percentage is therefore only fixed once Statbel has the December index. Statbel publishes a month's figures on the second-to-last working day of that month; last year Securex announced the PC 200 percentage on 23 December.

Every other committee uses its own reference period, and the official percentage then appears in the minimum wage database of the Federal Employment Service. Until then payroll providers work with the outlook of the Federal Planning Bureau; the figures on this page rest on the round of 3 November 2026.

How the centenindex works above 4,000 euros

The centenindex has applied since 1 June 2026, at each sector's indexation moment. If your reference pay is above 4,000 euros a month, you get the first 2% of indexation only on those 4,000 euros; whatever the indexation adds above 2% applies to your full pay. Up to and including 4,000 euros your pay is fully indexed.

The reference pay is the fixed gross monthly wage from the pay scale or your contract, converted to full time. Overtime, meal vouchers, bonuses, end-of-year premium, eco-vouchers and night or weekend supplements do not count. Neither you nor your employer can deviate from it. A second period is planned from 1 January 2028, but according to the FPS that date can still move. The centenindex calculator shows what it means for your pay.

Why not every sector rises in January

Automatic indexation in Belgium is arranged per joint committee, not per person. A committee chooses its own rhythm: once a year on a fixed date (January for PC 200, food and electricians among others, February for garages, July for metal), every quarter as in construction, or each time the pivot index is exceeded as in chemicals. Those who get nothing in January therefore get their indexation later in the year.

The percentage differs too, because each committee compares a different index and reference period. In a few committees, such as construction and road transport, the amount is calculated on the minimum wage of your category and you get that amount in euros, not the percentage on your full pay. The detail page of your committee states which rule applies.

What to do now as an employer

If you are an employer, check per group of employees which joint committee they fall under and when that committee indexes. Indexation is not a favour: the wage norm law guarantees indexations and pay scale increases, even in a period with a wage norm of zero. Your payroll provider applies the official percentage once it is known, but the budget is your responsibility.

For staff earning more than 4,000 euros a month, include the centenindex: there the increase is lower than the percentage suggests. Base your budget on the latest forecast and allow for a shift until the final figure arrives at the end of December.
