Record-keeping obligations are one of those topics that Belgian employers tend to discover at the worst possible moment: during a labour inspection, a payroll dispute, or a request from the NSSO. Getting clarity on retention periods and storage requirements before that moment arrives is straightforward, and it pays dividends.
Legal retention periods: which document, how long?
Belgian law does not apply a single blanket retention period to all employment records. Different rules apply depending on the nature of the document.
Core social documents The individual account (individuele rekening / compte individuel), payslips, attendance records and employment contracts must be kept for five years from the end of the calendar year to which they relate. That five-year clock also applies to end-of-contract documents such as the final settlement and the C4 unemployment certificate.
Fiscal and accounting documents Payroll-related tax documents, including the 281.10 salary certificate and records of withheld professional withholding tax, fall under the general seven-year fiscal retention rule. This aligns with the retention period set out in Belgian accounting legislation for bookkeeping records more broadly.
Working-time registration data This is an increasingly important category. As Belgium moves toward mandatory working-time registration for virtually all employees by 2027, clock-in and clock-out times, break records and overtime logs are becoming core compliance documents in their own right. What a legally valid working-time record must contain is defined by regulation. Keep this data for at least five years.
Works regulations The current version of the works regulation (arbeidsreglement) must be permanently accessible. Previous versions should be retained for five years after they are superseded.
Paper or digital: how to store records properly
Paper storage remains legally permissible in Belgium, but it carries obvious practical risks: fire, water damage, fading ink, misplacement. Digital archiving is more robust provided you follow a few principles.
- Long-term readability: use durable file formats such as PDF/A. A file that cannot be opened in seven years is worthless to an auditor.
- Integrity and tamper-evidence: records must not be alterable after the fact without that change being visible. Server-side timestamping and a clear audit trail address this requirement.
- Access control: only authorised staff should be able to view or export records. Role-based permissions are the standard approach.
- Backup and recovery: maintain at least one backup copy on a separate physical location or cloud environment, so that a single incident cannot destroy everything.
- GDPR compliance: employee personal data may not be retained longer than necessary. Document your processing activities in your GDPR register and set deletion schedules accordingly.
Tikkit timestamps every clock-in and clock-out at the server level and retains the full record history throughout the applicable retention period. When an inspection arises, an inspector-ready export can be produced in minutes, without hunting through archived spreadsheets or paper folders. That structured data also flows cleanly to your accountant, where accurate time records directly reduce payroll errors.
What inspectors actually look for
During a Social Inspectorate or Labour Laws Control visit, inspectors typically focus on a consistent set of documents:
- The individual account for each employee
- Attendance records or equivalent working-time registration data
- Employment contracts and any addenda
- Dimona declarations, particularly for flexi-job workers and students
- Evidence of wages paid and social contributions deducted
The ability to produce these documents quickly and in an organised way matters. An employer who hands over a clean, complete file projects confidence and generally shortens the inspection process. One who cannot locate records from three years ago faces unnecessary scrutiny.
Practical steps to get your record-keeping in order
- Draw up an internal matrix listing each document type, its retention period and where it is stored, digitally or physically.
- Set an annual calendar reminder to archive or securely destroy documents whose retention period has lapsed, in line with your GDPR obligations.
- Confirm that your time registration system can export data in a standard, durable format that will still be readable years from now.
- Align with your social secretariat or accountant on the retention periods you apply, so that everyone in the chain follows the same rules.
Strong record-keeping is not a bureaucratic burden. It is a quiet form of protection: for the business in the event of a dispute, for employees who need accurate records of hours worked, and for anyone involved when an inspection comes knocking.
