Working-time registration has been a fixture of Belgian labour law for years, but the 2027 deadline that will make it compulsory for virtually all employers is prompting a more urgent question: what does a legally valid record actually need to contain? Get it wrong and you are exposed during a social inspection. Get it right and you have a ready-made shield for both employer and employee.
The minimum data a valid record must include
Belgian legislation and the associated social inspection guidelines are clear on the core elements:
- Start time: the exact moment the employee begins work, not rounded to the nearest quarter-hour.
- End time: the moment work effectively stops, again to the minute.
- Breaks: every interruption must be logged separately, with its own start and end time. A standing lunch break that is never actually recorded does not constitute adequate proof.
- Worker identity: full name and preferably a staff number, so the record is unambiguously tied to one individual.
- Date and work location: for employees who move between sites, location is not optional detail, it is essential context.
These elements are not bureaucratic padding. They feed directly into the calculation of working hours against the standard 38-hour week and the daily and weekly overtime thresholds. Without a start time and an end time, there is simply no way to verify compliance.
Corrections: keeping them valid without destroying the original record
Mistakes happen. An employee forgets to clock out, a manager notices only the next day that a break was never logged. Corrections are permitted under Belgian labour law, but they must meet specific conditions to retain their legal weight:
- The original entry must never be overwritten or deleted. The initial data must remain visible alongside the correction.
- A full audit trail is required: who made the change, when, and why?
- Corrections should ideally require approval from an authorised person, such as an HR manager or direct supervisor.
- Employees should be able to view their own records and see any adjustments made to them.
A standard spreadsheet almost never meets these requirements. Cells can be edited without leaving any trace, which is precisely what social inspectors flag as problematic. It is one of the core reasons Belgian SMEs are moving away from spreadsheets toward dedicated time-tracking software.
Tamper-evidence: the requirement most employers overlook
Tamper-evidence is the single most underestimated element of a compliant time-registration system. A valid system must be able to demonstrate that data has not been altered after the fact without detection. In practice, that means three things:
- Server-stamped times: the timestamp is applied by the system at the moment of registration, not derived from a local device clock that could be manipulated. The article on why server-stamped times matter more than spreadsheet entries goes deeper on this point.
- Immutable logs: each entry receives a timestamp that cannot be changed without generating a visible correction record.
- Granular access rights: not everyone in the organisation should be able to edit time records. Who can do what must be defined and logged.
Tikkit applies a server-stamped time to every clock-in and clock-out event and maintains a full correction history that is visible to both employer and employee. If an inspector asks to review records for a specific period, the complete picture is available immediately, nothing needs to be reconstructed from scattered sources.
For teams working on a shared site, Tikkit's QR code and kiosk clock-in options allow workers to register their time quickly and verifiably without relying on personal smartphones.
Retention and accessibility: the long game
A compliant record is not just one that contains the right data today. It must also be retained for long enough. Belgian social documents are generally subject to a five-year retention requirement. That means your system needs to archive data in a durable, structured and accessible format, not on a local hard drive that may not exist in three years.
Accessibility matters too. If an inspection request arrives, you need to be able to produce the relevant records promptly and completely. A system that forces you to compile data from multiple sources before you can respond is a liability, not an asset.
A well-configured time-registration system is ultimately a form of protection: for the employer who wants to demonstrate compliance, and for the employee who deserves an accurate record of their own working time. Building the right habits now means facing 2027 with confidence rather than last-minute panic.
