Mandatory Time Tracking in Belgium (2027) + Compliance Checklist

Is time tracking mandatory in Belgium? Where things stand as of October 2026

No, time tracking is not mandatory in Belgium as of October 2026. Here’s a quick list of what’s been confirmed and what is likely to happen next:

Why Belgium is introducing mandatory time registration

Belgium is introducing mandatory time registration because a 2019 European Court of Justice (ECJ) ruling requires Belgium (and other EU countries) to adopt and implement a time registration law to comply with the Court’s decision (which is an interpretation of EU Directive No. 2003/88/EC).

In late 2025, Belgium’s authorities launched legislative action to make time tracking mandatory. The Belgian Chamber of Representatives, the Government, and other authorities are currently considering the draft law and resolutions.

Another reason for introducing mandatory time registration is that the new law will settle the burden-of-proof issue. Until now, some labor courts have placed the burden of proving unpaid overtime on employers without time records. In other words, the employer has to provide evidence that the claimed hours were not actually worked.

Labor courts also refer to the EU Time Tracking Law, which requires employers to implement an objective, reliable, and accessible system “to measure the daily working time of each employee.”

Who has to comply and who may be exempt

All employers in the private and public sectors must comply with the upcoming Belgian time tracking legislation. As of 2026 and according to the Federal Public Service for Employment, Labor and Social Dialogue, the following are categories of workers who are exempt from working time regulations based on the Belgian Labor Act of 16 March 1971:

• Persons in a position of trust or management (such as a company director, branch manager, or high-level executive) — their roles are evaluated by output and responsibility rather than hours logged. They don’t have a standard schedule, so these positions don’t require time tracking.
• Commercial representatives — their work involves traveling to visit clients outside the company premises, so they manage their schedule autonomously to meet business needs. An employer can’t directly supervise the daily start and end times of commercial representatives; thus, it’s legally and practically impossible to subject them to rigid work time tracking.
• Home workers or teleworkers — they manage their work autonomously, outside the employer's direct physical control.
• Workers in a family business — companies where only relatives work together under the supervision of a parent, or relative are excluded from hourly time tracking under Belgian law.

All exempted categories are expected to remain in place under the 2027 time registration law.

Note that this is not a final list of exemptions (we may expand it by the end of 2026 to make sure it’s up to date).

🎓 Can Companies Track Work Hours? Full Guide & Accuracy Tips

What you’ll need to record

To stay compliant with upcoming time tracking law, simplify inspections, and prevent disputes about working hours, Belgian employers must record the following baseline information:

• Daily start and end times
• Duration and timing of mandatory breaks or interruptions
• Overtime hours and schedule deviations
• Rest periods between consecutive shifts

However, absences like vacation, training, and sick leave aren’t explicitly mentioned in the formal documentation as of 2026.

Time registration in Belgium in 2027 is about to get a lot more complicated. Time tracking systems like Clockify by CAKE.com help employers meet these requirements easily:

#1: Start and end times: Employees get to track work hours using the Timer, Timesheet, or Manual mode. Managers can review these work hours and approve or reject timesheets.

#2: Breaks and interruptions: Clockify records mandatory rest periods accurately across web, mobile, and Kiosk. When your team tracks breaks separately from work hours, you get a more accurate representation of actual productive hours. (This matters when you bill clients by the hour or calculate labor costs.)

#3: Overtime and schedule deviations: Clockify automatically calculates overtime, flags schedule mismatches, and locks timesheets for compliance approval. To track overtime easily, Clockify lets you set employee daily capacity (e.g., 8 hours). Any hours an employee tracks beyond those 8 hours are automatically calculated as overtime.

The requirements a compliant time tracking system must meet

Here are some of the known requirements a compliant time registration system in Belgium must meet as of 2027.

Requirement #1: Time tracking must be objective

The time tracking system must record the time employees actually worked, without one-sided manipulation. According to the ECJ ruling, time measurement must be based on factual data rather than estimates. The Court stated that, without an objective system, it is “excessively difficult, if not impossible in practice, for workers to ensure that their rights are respected.”

Requirement #2: Time tracking must be reliable

Records can’t be changed unilaterally by either side (the historical data integrity must be preserved). According to the ECJ ruling, the system must be immune to tampering, as the workers are “structurally the weaker part in an employment relationship.” This means that a reliable time registration system prevents employers from arbitrarily altering hours or pressuring employees to underreport their time.

Requirement #3: Time tracking must be accessible

Accessible time tracking means the inspection service, the courts, and the employee can all see the records. In other words, neither employers nor employees can hide the records.

Requirement #4: Time tracking must be complete

Breaks, overtime, and rest must be recorded for each 12-month period. The time registration system must record the full chronological scope of a workday. Logging “8 hours worked” is not legally sufficient. You must also record the duration of paid and unpaid breaks, and the exact start and end times. In Paragraph 50l, the ECJ specifies that a system must prove whether the mandatory minimum daily rest period (11 consecutive hours) was respected.

Rules that already apply today

Belgium currently enforces strict, highly specific time-and-attendance registration rules based on the type of work contract and sector. Here are 5 rules you need to consider:

Rule #1: Flexi-jobs

Flexi-jobs allow workers to earn untaxed supplemental income, but employers must adhere to strict time registration scrutiny to prevent abuse. If an employer uses a written framework contract for a flexi-worker, the employer can’t simply register the worker for a whole quarter without tracking their exact daily hours.

Rule #2: Flexitime

Flexitime was introduced in 2017 and allows employees to choose their own working hours within mandatory core periods. Since the schedule fluctuates daily, the law explicitly requires employers to use a digital time tracking system to calculate whether the employee has met their required weekly hours or accrued legal overtime.

Rule #3: Checkinatwork

Checkinatwork was introduced for industries with a high risk of social fraud and undocumented labor, like construction, cleaning, transportation, and logistics. Checkinatwork requires real-time geolocation and attendance logging at the exact work site.

Rule #4: Part-time deviations

Part-time deviations mean that if a part-time employee works outside their formally published schedule (starting earlier, ending later, or working during a scheduled break), the employer must record the deviation immediately.

The part-time deviations rule applies to both fixed and variable part-time schedules. According to the Federal Public Service Employment, employers must use a reliable time tracking system (like an app or a digital clock) or a specific paper deviation document.

Rule #5: Horeca daily registration

Horeca daily registration means that the employer (or their representative) must “communicate the daily start and end times of employment for permanent workers” in the hospitality industry. There are 3 types of daily registration declarations:

• In (to register a worker’s presence)
• Update (to modify the presence registration)
• Cancel (to cancel the presence registration)

Clockify Kiosk lets hospitality workers check in, take a break, and check out easily. Employers can choose how employees clock in and out: with PIN, QR code, or photo capture.

Time tracking and Peppol e-invoicing: 2 Belgian mandates, 1 workflow

Peppol BIS is the Belgian government’s preferred invoicing format. If employers lack the technical means to issue and receive a structured electronic invoice, the authorities will impose fines of:

• €1,500 for the first offense
• €3,000 for the second offense
• €5,000 for subsequent offenses

To comply with mandatory time tracking in Belgium and Peppol requirements, you can use the Clockify-Peppol integration. If you bill by the hour, you can:

• Have employees track time and submit timesheets in Clockify
• Approve or reject the timesheets
• Create an invoice in Clockify
• Send the invoice via Peppol integration

That way, you ensure full compliance with a quick, single workflow.

The Sent invoices tab gives you maximum customization: set invoice status to Due, Sent, Rejected, Pending, and more. That way, you can speed up client payments and avoid critical data slipping through the cracks.

FAQs about Belgium time tracking law

To wrap up, here are 6 frequently asked questions about the upcoming time registration law in Belgium.

Is the 4-day workweek legal in Belgium?

Yes, the 4-day week is legal in Belgium, since it was officially introduced as part of the country’s 2022 Labor Deal. The legislation allows full-time employees to compress their standard working hours into 4 days instead of 5.

With this schedule, employees work longer hours per day (up to 9.5 hours) to earn an extra day off. At the same time, employees don’t experience any reduction in salary or benefits.
