🎓 How many hours can I work as a student in Belgium?

With conditions

Quick answer

650 hours per calendar year — at a mini-contribution, and since 2026 that cap is permanent. As a student worker you don't pay ordinary social contributions but a solidarity contribution of 2.71 percent (employer: 5.43), as long as you stay within the 650-hour quota — the once-temporary increase was structurally anchored from 1 January 2026. Work more and from hour 651 you switch to full social security (13.07 percent) — working stays allowed, it just nets less. Your live counter sits in the Student@work app; hand employers the certificate, they plan around it. Two traps beyond the hours: child benefit (Groeipakket) — regionally tied to those 650 hours — and the tax threshold for staying dependent on your parents, generous since the reform (±€22,400 gross in 2026) but still real.

📋 The rules

Quota: 650 hours per calendar year at 2.71 % contribution
Since 1/1/2026 structural — no more yearly uncertainty
From hour 651: full social security (13.07 %) — working stays allowed
Counter and certificate: Student@work app / studentatwork.be
Beyond 650 h: child benefit may be at risk (regional rules)

🔓 Exceptions

Staying a tax dependant: own income ceiling (±€22,400 gross in 2026) — separate from the hour counter
A student employment contract is mandatory; night and hazardous work stay restricted for minors
Beyond 650 hours you may simply keep working: you lose the favourable rate, not the right to work

⚠️ Penalties & fines

Going over 650 hours carries no fine, but it does carry a bill: from hour 651 you pay the full social-security rate of 13.07 percent instead of the 2.71 percent solidarity contribution, and your employer pays full contributions too. Your gross stays, your net drops. On top of that, child benefit for that period can fall away — that is regionally arranged, and Flanders ties the Groeipakket to the very same hour cap. Work without a student contract and your employer risks social-security requalification and sanctions, while you lose the favourable regime.

❓ Frequently asked

What happens if I exceed 650 hours?

From hour 651 you pay 13.07 percent and your employer pays full social security, instead of the solidarity contribution. Your net drops, and depending on your region child benefit may also be at risk.

How do I check my remaining hours?

Via the Student@work app or studentatwork.be: you see your remaining counter and download the certificate employers ask for. Employers plan around that certificate, so check it before you sign a new contract.

Will working cost me child benefit?

Within 650 hours you are safe. Beyond that it depends on your region: Flanders ties the Groeipakket to the very same 650-hour cap, so working on past it can cost you the benefit for that period — no fine, just a loss.

Do I stay a tax dependant of my parents?

Yes, as long as you stay under the own-income ceiling — generous since the reform, around €22,400 gross in 2026. That ceiling is independent of the hour counter: you can stay under 650 hours and still exceed it.

Do I need a student employment contract?

Yes, it is mandatory. Without one your employer risks social-security requalification and sanctions. For minors, night work and hazardous work also stay restricted, even within the 650-hour quota.
