If you run a service business in Belgium and haven't heard about the new working time registration obligation yet, you're not alone — but the clock is ticking.
From 1 January 2027, every Belgian employer — regardless of company size, sector, or whether your team works remotely, on-site, or hybrid — must implement a system to record each employee's daily working hours. The obligation is set in federal law, directly grounded in a European Court of Justice ruling, and it comes with real enforcement teeth.
Here's everything you need to know, without the legal jargon.
Where does this law come from?
The obligation traces back to a 2019 ruling by the Court of Justice of the European Union (CJEU) in case C-55/18 (CCOO v. Deutsche Bank SAE). The Court concluded that without an objective, verifiable system of daily working time measurement, employees cannot effectively exercise their rights under the EU Working Time Directive — and member states cannot enforce those rights either.
Belgium has now formally implemented this ruling as a federal obligation, confirmed in its 2025 budget agreements: all employers must comply by 1 January 2027. A transitional grace period until 31 March 2027 is being communicated to give businesses time to get fully operational, but the legal obligation starts on 1 January.
Who is affected?
Virtually every Belgian employer. The law applies across:
- All sectors — not just construction, cleaning, or hospitality where prior registration rules already existed
- All company sizes — from a 2-person consultancy to a 200-person professional services firm
- All employment types — full-time, part-time, temporary, and posted workers
If you have employees in Belgium, this applies to you.
What does a compliant system actually need to do?
The law doesn't mandate a specific technology — no physical punch clock is required. But whatever system you choose must meet three non-negotiable criteria:
1. Objective
The system must automatically record actual hours worked — not pre-set schedules, not estimates, not "what we agreed." It must capture start time, end time, and breaks for every employee, every working day.
❌ An Excel sheet employees fill in on Friday afternoon does not qualify.
2. Reliable
Data must be accurate and tamper-evident. If anyone edits a time entry — for any reason — the system must log who made the change, when, and what the original value was. An unlogged correction is a compliance gap.
❌ A basic time tracker with no audit trail does not qualify.
3. Accessible
Both the employee and the Belgian social inspectorate must be able to access records at any time. Employees must be able to verify their own data. Inspection authorities must be able to audit on demand.
❌ A system locked behind admin-only credentials does not qualify.
What are the risks of non-compliance?
The Belgian Social Criminal Code gives inspectors the tools to enforce this. Non-compliant employers face:
- Administrative fines per employee per violation
- Ordered remediation — mandatory implementation under supervision
- Criminal prosecution in cases of repeated or serious infringement
- Reversed burden of proof in labour disputes — without objective records, the employer is disadvantaged when an employee claims unpaid overtime
For a service business where hours worked is the product, having unreliable or non-compliant records is both a legal and commercial risk.
What does NOT qualify as compliant?
To be explicit about common misconceptions:
| Tool | Compliant? | Why not |
|---|---|---|
| Standard Excel sheet | ❌ No | No automatic recording; no audit trail |
| Paper presence lists | ❌ No | Not objective; not auditable digitally |
| Self-reported weekly summaries | ❌ No | Not objective; not real-time |
| Basic mobile time tracker (no audit log) | ⚠️ Probably not | Depends on whether edits are logged |
| Scheduling software only | ❌ No | Records planned hours, not actual hours |
| Integrated PSA with time logging + audit trail | ✅ Yes | Meets all three criteria |
What does compliant look like in practice?
A compliant system for a service business typically:
- Logs time as employees work — tied to tasks, tickets, or projects
- Captures start/end time and breaks automatically or with minimal manual input
- Maintains a full, immutable audit trail of any edits
- Allows employees to view and verify their own data at any time
- Exports data in a structured format (CSV, PDF, XML) for inspection
Critically, if your operational platform already logs how your team spends their time as part of normal workflow, you may already be most of the way there — you just need to verify the audit trail is present.
What steps should you take now?
Step 1 — Audit your current setup
Does your current tool automatically log start and end times per employee, per day? Pull the data and check. Not what's scheduled — what's actually recorded.
Step 2 — Check your audit trail
Can you prove who changed a time entry, when, and what it said before the change? If not, your system won't pass inspection.
Step 3 — Update your work regulations (arbeidsreglement)
Belgian law requires that changes to time registration systems be reflected in official work regulations. This process typically involves a 15-day consultation period and, where applicable, involvement of a works council or union delegation. Start this now — it takes time.
Step 4 — Inform your employees
Every employee must know how the system works and be able to access their own records. Build this into your onboarding and internal communications.
Step 5 — Integrate with payroll
The strongest setups connect time data directly to payroll and project billing. This eliminates double entry and creates a single, auditable source of truth.
The opportunity hidden inside the obligation
Here's the part most compliance articles miss: a system that meets the 2027 standard isn't just a legal checkbox — it's operational infrastructure.
Service businesses that get this right will have:
- Real-time insight into where their team's hours actually go
- Accurate project profitability tracking
- Cleaner invoicing tied to verified time data
- Stronger legal protection in any future labour dispute
The businesses scrambling to comply in December 2026 will implement something rushed and minimal. The businesses that act now can implement something that genuinely improves how they operate.
