What is a freelancer? Definition and legal framework in Belgium

A contractor offers to work with you "as a freelancer" and you are not entirely sure what that commits you to. The word is common, but it matches no legal status in Belgium. Here is what it actually covers, what the law does regulate, and what you can check before signing.
"Freelance", "self-employed", "consultant": what do these words mean?
The word "freelance" comes from usage, not from Belgian law. No text defines it. The real status behind it is that of self-employed worker: the Programme Act of 27 December 2006 describes this person as a natural person who carries out a professional activity outside any relationship of authority and who is not bound by a statutory appointment.
The three words therefore do not describe the same thing.
- Self-employed is a social security status. It is the only one of the three that exists in law.
- Freelance describes a way of working: successive assignments, for several clients, without an employment contract.
- Consultant describes the content of the work, advice. A consultant can be an employee of a firm; a freelancer may give no advice at all
One last distinction matters in practice: a freelancer can work as a natural person or through their own company. In the second case, your contract binds two businesses. That changes the invoicing and the way liability is shared, not the nature of the work delivered.
The subject is not marginal. According to INASTI (Figures and trends 2025), Belgium counted 1,327,994 self-employed workers on 31 December 2025, of whom 820,978 as their main occupation.
What information does a freelancer in Belgium need to fill out, and what can you verify?
Registration with the Crossroads Bank for Enterprises , through a business counter, which gives them a company number and declared activities..
Affiliation to a social insurance fund which triggers their social contributions. These reach at most 20.5% of net taxable professional income (INASTI, 2026).
A VAT regime suited to their activity, either liable or exempt under the small business scheme.
Professional liability insurance where the activity requires it.
Before signing, three requests are enough: the company number, which can be checked free of charge in the Crossroads Bank for Enterprises, the affiliation certificate from the social insurance fund, and the insurance certificate.
A serious contractor supplies them within minutes. These documents do not on their own prove that the collaboration is genuinely self-employed, but their absence is a signal.
Tip : ask your accountant, they can help you with that!
What is the real risk for the client company?
The main risk is not the quality of the work: it is reclassification as an employment contract. The 2006 act sets out four general criteria for assessing whether a relationship of authority exists:
the will of the parties as expressed in their agreement,
the freedom to organise the work,
the freedom to organise working time,
and the possibility of exercising hierarchical control.
No criterion counts on its own. It is their convergence that decides. The title of the contract, registration with the Crossroads Bank for Enterprises or VAT liability are not enough: taken in isolation, these elements determine nothing.
A common situation: an administrative profile present in your offices four days a week for eighteen months, with imposed hours, an assigned desk, a manager who approves their time off and no other client. On paper this is a self-employed collaboration. In practice, the question arises. If the relationship is reclassified, the client company becomes the employer and has to regularise the corresponding social security contributions.
Prevention comes down to three habits: define the assignment by an expected result and a duration, let the contractor organise their own work, and avoid folding them into your staff management tools such as the holiday planner, appraisals or the internal org chart.
Key points to remember
"Freelance" is a word of common usage; the Belgian legal status is that of self-employed worker.
Consultant describes a service, self-employed describes a status: the two do not overlap.
The real risk for the client company is reclassification , assessed on four converging criteria.
A mission defined by a result , and not by a attendance , protects both parties.
Frequently Asked Questions
Can a freelancer work for only one client?
Yes, the law does not prohibit it . But lasting exclusivity, combined with imposed hours and hierarchical control, strengthens the body of evidence pointing to a relationship of authority.
Is a written contract required with a freelancer?
It's not mandatory, but it's highly recommended . The written agreement sets the assignment, the expected result, the duration, the price and the ownership of the deliverables. It also evidences the will of the parties.
Does a freelancer cost more than an employee?
The daily rate is higher, but the total cost is not necessarily . There is no holiday pay, no notice period, no employer contributions, and the commitment ends with the mission.
In conclusion
The word "freelance" says nothing about the legal framework: it only says how someone works. What counts is the self-employed status, the documents that prove it and the way the collaboration actually runs.
A well-defined assignment protects better than a cautious contract that is poorly applied. That is the first point I check with a business owner before formalising an external collaboration.
