Belgium's Student Job Rules: The 475-Hour Quota Explained

Why everyone still says "475 hours"

Belgium's student job quota sat at 475 hours a year for a long stretch, and the number stuck in everyday conversation even after it changed. A temporary pandemic-era increase lapsed when the federal government entered a caretaker period without the authority to extend it, so the quota briefly fell back to 475 hours. Student@Work , the official portal for tracking student job hours, confirms the new federal government raised the quota to 650 hours retroactively from 1 January 2025, and it stays at that level going forward. Job listings, employer paperwork, and even some university career centers still reference the old figure out of habit, so double check any hour number you see against Student@Work directly rather than assuming an older source is current.

The current quota: 650 hours a year

Every student gets a 650-hour package per calendar year across all employers combined, not per job. The package resets on 1 January regardless of when you started working that year, and unused hours do not roll over into the next year.

Getting the contract right

A student job needs its own written student employment contract, separate from a standard employment contract, for the reduced contribution rate to apply. Ask your employer directly whether the contract is a student contract before your first shift, since a normal contract by mistake means normal social contributions from day one regardless of your enrollment status.

Who qualifies as a student worker

The reduced student contribution applies to anyone enrolled as a student in day-time education, working under a specific student employment contract rather than a normal employment contract. Full-time workers who study part-time on the side generally do not qualify for the scheme, since it targets students whose main activity is their studies.

How the reduced contribution rate works

Inside your 650-hour package, you pay a reduced social security contribution of 2.71 percent of gross salary instead of the standard 13.07 percent that applies to regular employees, according to Student@Work . This reduced rate is the entire point of the student job status: it keeps take-home pay noticeably higher than a normal part-time contract gives for the same gross wage.

Tracking your hours

Employers report each shift through Dimona, Belgium's standard employment declaration system, and Student@Work pulls that data to show your remaining balance in real time. Check your balance through the Student@Work website or app before accepting extra shifts, since going over the quota without knowing it catches many students by surprise partway through the year.

What the rate difference means in practice

On a 1,000 EUR gross monthly wage, the 2.71 percent student rate takes about 27 EUR in contributions, against roughly 131 EUR under the standard 13.07 percent rate applied to a normal employee on the same gross pay. That gap is why students protect their 650-hour package carefully rather than treating it as a minor detail on a contract.

What happens past 650 hours

Hours worked beyond the 650-hour package still count as student employment and do not cost you your student status, but the normal social contribution rate of 13.07 percent applies to those extra hours instead of the reduced rate. Net pay per hour drops for anything worked past the quota, so plan remaining shifts around the balance shown in Student@Work rather than seeing the change on a payslip after the fact. The drop applies only to the extra hours, not retroactively to hours already worked inside the package earlier in the year.

Regional differences exist

The 650-hour package is a federal, national quota, but Brussels, Flanders, and Wallonia apply some of their own supplementary rules on top of it for hours worked outside the reduced-contribution package. Check the regional guidance linked from Student@Work if you plan to work substantially more than 650 hours in a year, since the rules for those extra hours are not identical across the three regions.

Combining a student job with other income

A scholarship, family allowance, or a second student job does not reduce your 650-hour package, since the reduced-contribution scheme only tracks hours worked under a student employment contract, not total household income. Keep each employer's Dimona declaration in mind separately if you juggle two part-time roles, since your combined hours across both still count against the same national quota.

Practical tips

• Check your Student@Work balance before agreeing to extra shifts, especially around exam periods when employers often ask for more hours

• Remember the 650-hour cap applies across every employer combined, not per contract

• Ask your employer to confirm they registered your contract as a student job through Dimona, since a missing registration costs you the reduced rate entirely

• Plan higher-hour periods like summer around your remaining balance rather than the calendar month
