From 1 January 2027, Belgian employers are obliged to record working hours digitally and reliably. Anyone who meets that date without a compliant system risks more than an administrative shortcoming. The social inspectorate will have wider control powers and the sanctions are concrete.
In this article, you can read what risks HR managers and business managers run if they don't finish on time - and why delay is already more expensive than action.
đź“š Read here what the Belgian timesheet requirement of 2027 is.
The most important insights
- Companies without a compliant time registration system risk administrative fines from the first day of 2027. The social inspectorate does not have to wait for a complaint — it can proactively check.
- A missing or unreliable record is considered proof of non-compliance. The burden of proof lies with the employer, not on the inspectorate.
- Financial penalties can be imposed per employee. For larger teams, the exposure quickly rises to tens of thousands of euros.
- Reputational damage among customers and tenders is an underestimated risk. Consultancy and IT companies that work with government contracts or enterprise customers can be excluded from tenders in the event of non-compliance.
- The technical implementation of a new system takes an average of three to six months. Those who have not started at the beginning of 2026 will realistically no longer meet the deadline.
- Existing systems that now seem “sufficient” do not have to comply with legal requirements. An Excel sheet or a time registration module in an HR package often lacks the required audit trail.
What does the social inspection check?
The Belgian social inspection has the authority to monitor compliance with employment regulations unannounced. From 2027, digital time registration will also be explicitly under their supervision.
‍
During an audit, the inspectorate looks at three things:
- Presence of a system: Is there a digital registration that meets the legal minimum requirements?
- Completeness of the data: Are all employees registered, including part-time, seconded and project-based employees?
- Reliability of the registration: Does the system have an audit trail? Are changes traceable?
‍
The inspection can provide data about the past quinquennium inquire. If the registration is missing for part of that period, that in itself is an offence - regardless of whether you have a system at the time of verification.
‍
đź“Ś The regulations concerning mandatory time registration are still in effect at the time of publication. The political decision is firm. Concrete legislation, including sanctions and exceptions, will follow. Keep an eye on our blog for the latest updates.
What can you do now?
- Have it internally tested whether your current time registration system maintains an audit trail in case of changes.
- Make sure that all categories of employees — including freelancers, seconded, and part-time workers — are included in your current registration.
- Ask your HR advisor or social secretariat for a gap analysis of your current way of working in relation to the legal requirements.
The financial risks at a glance
Administrative fines
The amount of the fines for non-compliance with the time registration obligation is linked to the number of employees involved. The exact amounts are still laid down in implementing decrees, but the system follows the pattern of existing Belgian employment legislation: a basic rate per offence multiplied by the number of employees affected by the offence.
In practice, at a company of 50 employees, that amount can reach tens of thousands of euros per audit. In case of repeated or serious offences, higher penalties are possible.
Criminal risks
In addition to administrative sanctions, the Belgian Social Criminal Act also provides for criminal prosecution for serious or intentional offences. This goes beyond a fine: in exceptional cases, this can lead to personal liability for the business manager or HR manager.
Note: the threshold for criminal prosecution is high, but the risk increases if a company demonstrably knew about the obligation and has failed to act.
Recovery of subsidies and benefits
Belgian companies that use employer contribution reductions or other government incentives, these benefits may be lost if an audit shows that employment records were not in order. The NSSO explicitly links some benefits to correct time registration.
What can you do now?
- Have your legal advisor map out the sanctions structure of the implementing decrees as soon as they are published.
- Calculate internally what financial risk you run in the event of a penalty per employee, based on your current staff size.
- Make sure you're taking advantage of contribution reductions that are dependent on correct time registration.
Operational and legal risks
Employment disputes and evidence issues
Compliant time registration not only protects against inspection — it also protects in employment law disputes. Disputed overtime, discussions about leave, or conflicts about project deployment are much easier to resolve if a reliable, traceable record is available.
If this registration is missing or is not reliable, the employer is usually weaker in the event of a conflict before the employment court. The judge often interprets unclear or missing hours in favor of the employee.
Impact for consultancy and IT
Consultancy and IT companies often work with multiple clients at the same time and have employees who fill in their hours themselves - sometimes retroactively, sometimes on a project estimate. That model does not meet the 2027 requirements.
In addition, many of these companies work with government contracts or contracts with large companies that set their own compliance requirements. A non-conclusive time registration can lead to:
- exclusion of tenders that require compliance statements
- billing discussions with customers who want to check registered hours
- reputational damage in long-term customer relationships
Impact for secondment and temporary employment
There is an extra dimension for secondment companies: the employee works physically for a hirer, but the legal employment relationship lies with the secondment provider. The registration requirement applies to the legal employer. This means that a secondment company is responsible for the accurate time registration of employees who work for dozens or hundreds of different customers.
‍
Without a system that employees can use on location and on location, this is not feasible in practice.

What can you do now?
- Document your current time registration process by employee category: permanent employees, part-time workers, freelancers, seconded workers.
- Determine which groups are not yet registered or are incomplete.
- Check tender records and customer contracts for compliance clauses that relate to employment records.
The risk of starting too late
The biggest risk is perhaps the most underestimated: time pressure to implement.
Selecting, implementing and deploying a time registration system is not a matter of a weekend. Even in a relatively simple company of twenty employees, the process takes an average of three to six months - including supplier evaluation, setup, data migration and training.
When to start selection? These are the risks per timing
Will you start with the selection in Q1 2025, then you can realistically go live around Q3 2025, giving you a large buffer and plenty of time to optimize the system.
Are you starting in Q1 2026, then going live in Q3 or Q4 2026 is obvious. This is achievable, but leaves little room for setbacks.
Start your pass in Q3 2026, then the go-live will probably be postponed to early 2027 or later. Chances are you won't meet the deadline.
Are you starting in Q4 2026?, then you are almost certainly late and you will not be compliant by the effective date of 1 January 2027.
What can you do now?
- Put the selection of a time registration system on the agenda of the management team or board of directors this quarter.
- Appoint a responsible person - HR manager or operations lead - to lead the implementation process.
- Use Q1 2026 for evaluation and selection so you can use Q2 for deployment and Q3 for pilot phase and training.
TimeChimp helps you reduce risks
TimeChimp is designed for service companies that need to accurately record and account for hours — internally and externally.
- Audit trail: All changes are logged automatically, so that during an audit, you can show exactly who entered or changed what and when.
- Mobile registration: Employees register hours on location via the app, without dependence on office equipment.
- Export function: Data can be exported at any time in the formats that the social inspectorate expects.
- Project link: Hours can be traced back to the customer, project and task - essential for companies that invoice based on time.
- Data retention: TimeChimp stores data in accordance with the legal retention periods, so you can always look back if you check retroactively.
Conclusion
The risks of not being ready in time for the Belgian time registration obligation are real and multiple: financial fines, legal vulnerability in employment disputes, customer reputational damage and tenders, and the simple fact that an implementation process takes time that you still have — but not anymore.
HR managers and business owners who take action this year are not only reducing their compliance risks. At the same time, they are building a registration process that strengthens their organization: better insight, fewer disputes, and a comprehensive administration for customers and inspection.

FAQs
Naast de financiële boetes lopen consultancy- en IT-bedrijven twee extra risico's. Ten eerste uitsluiting van aanbestedingen: overheidsopdrachten en enterprise-contracten bevatten steeds vaker compliance-clausules over arbeidsregistratie. Ten tweede factuurgeschillen: klanten die de geregistreerde uren willen controleren, kunnen bij een niet-sluitende registratie de factuur aanvechten. Beide risico's raken direct de omzet en klantrelaties.
The exact amounts of fines are laid down in implementing decrees, but the system follows the pattern of existing Belgian employment legislation: a basic rate per offence multiplied by the number of employees involved. At a company of 50 employees, that can amount to tens of thousands of euros per audit. In the event of repeated or intentional violations, increased sanctions and — in exceptional cases — criminal prosecution are possible.

Yes. From 1 January 2027, a general obligation to record time will apply to all employers in Belgium, regardless of sector, company size or employee status. The obligation replaces the existing sectoral exceptions.
