Self-employed or employee in Belgium? How status is decided

In Belgium, whether someone is self-employed or an employee depends on how the work is actually carried out, not on the title of the contract. The rules sit in Title XIII of the Programme Law (I) of 27 December 2006, on the nature of employment relationships, and they start from a simple position: the label the parties chose is respected unless the way the work is performed contradicts it.

That starting point gives freelancers and their clients real room. Two parties who genuinely intend a self-employed arrangement, write it down and then behave accordingly will usually see that choice stand. The risk appears when the paperwork says one thing and the working week says another. A services agreement with fixed hours, a manager who sets daily tasks and a laptop supplied by the client tells a story the agreement cannot override.

The law sorts the evidence into three layers. Neutral criteria are elements the law treats as inconclusive: they can be noted, but they cannot decide the question by themselves. General criteria apply to every relationship and carry the real weight. Specific criteria come into play only in sectors the law singles out, where they trigger a presumption. The FPS Employment summary of the rules, nature of the working relationship, sets out the full text.

Four general criteria decide most cases, and an inspector or a labour court weighs them together rather than ticking one box.

• The parties’ intention. What the contract says counts, provided it matches what happens in practice.
• Freedom to organise working time. Can the person choose when to work, or are hours, attendance and leave set by the client?
• Freedom to organise the work itself. Does the person decide how to deliver the result, or receive instructions on method and sequence?
• The possibility of hierarchical control. Could the client supervise and direct the person as a manager directs staff? The possibility is enough; it need not be exercised every day.

For a remote software developer or marketing specialist, the criteria translate into everyday questions. Does the person attend fixed daily meetings because they are told to, or because the project needs a weekly check-in they agreed to? Do they request time off from your team lead? Do they sit in your org chart, carry your job title and report through your performance review cycle? Each “yes” moves the picture towards employment.

Some facts point the other way. Working for several clients at once, setting one’s own rates, sending invoices for defined deliverables, carrying one’s own tools and bearing commercial risk all sit more comfortably with genuine self-employment. None of them is decisive alone, which is why a contractor who has only one client and works full-time under your direction is the classic problem case even when every invoice is in order.

Two profiles show how far apart the outcomes can be. A brand designer in Leuven who works for three companies, quotes a price per project, uses her own software and delivers files by an agreed date fits the self-employed picture well. A developer in Mons who has invoiced one client every month for eighteen months, joins its sprint planning, takes leave when the team lead approves it and uses a company laptop and email address looks like an employee in all but name. Both may hold identical freelance agreements; only one of those agreements describes reality.

In seven areas of activity, the 2006 law reverses the burden: the relationship is presumed to be employment when more than half of a list of specific criteria are met. The areas are construction, security, transport, cleaning, agriculture, horticulture and work through digital platforms.

The presumption can be rebutted with evidence that the person really works independently, and it does not apply to relationships between family members. But the starting point matters in practice. A courier for a delivery app or a cleaner engaged through an online platform begins from “employee”, and the client must show why that is wrong rather than the other way round.

Most foreign companies hiring their first person in Belgium are not in these sectors. A product manager in Ghent or an account executive in Liège will be judged on the four general criteria alone. The platform category is the one to watch for technology businesses: if your product matches workers with customers, take advice before engaging people in Belgium on freelance terms.

Belgium offers a formal way to settle status in advance: the Administrative Commission for the Settlement of the Employment Relationship (Commission administrative de règlement de la relation de travail / Administratieve Commissie ter regeling van de arbeidsrelatie). Either party can ask it to look at a specific arrangement.

The commission gives two kinds of answer. Advice is non-binding. A decision, by contrast, binds the FPS Social Security, the FPS Employment, the ONSS, INASTI (the national institute for the self-employed) and the self-employed social insurance funds. A request must be made before the relationship starts, or within one year of its start or of a new element that changes it. The commission’s procedure page explains how to file.

A ruling is most useful when the arrangement is unusual and both sides want certainty, for example a senior specialist who will work on a long project for one client but keeps other customers. It is less useful when the facts plainly point to employment. If you already manage the person like a member of staff, a ruling will most likely confirm what you can see for yourself.

If an arrangement is requalified, it is treated as an employment contract, and both the social security and the labour-law consequences follow. The two sets of costs stack.

On the social security side, contributions become due as if the person had been on payroll: the employer share of 25.00% of gross pay in 2026 for a private-sector white-collar worker, and the employee share of 13.07%, plus surcharges and late-payment interest. Any contributions the person paid as self-employed do not simply cancel this out. To give a sense of scale, on pay equivalent to €4,500 a month the employer share alone is €1,125 for every month of the relationship.

On the labour-law side, the person acquires an employee’s rights for the period. These include:

• Notice or an indemnity in lieu if the relationship is ended, calculated on seniority from the real start date. Two years of service already means 12 weeks.
• Holiday pay, including double holiday pay of 92% of a monthly salary for each full reference year.
• Guaranteed salary for periods of sickness, at 100% for the first 30 days for a white-collar worker.
• The protections that come with joint committee pay scales, the 13th month under PC 200 and the work regulations.

Add the cost of advisers, the management time spent rebuilding records for past quarters and possibly a labour court case, and a requalified two-year freelance relationship can cost more than two years of correct employment would have.

The most common version of the problem looks like this: a company with no Belgian presence finds the right person in Antwerp or Namur, cannot employ them quickly, and signs a consultancy agreement instead. Months later the person works full-time for that one client, reports to a team lead and appears in the company directory. The paperwork still says self-employed.

Being abroad does not take the client outside the 2006 rules. The person works in Belgium, so Belgian social security and labour law look at the relationship as it is lived there. Requalification can also leave the client as an employer with no Belgian payroll registration, which creates its own catch-up work with the ONSS. The person, meanwhile, may have paid self-employed contributions to a social insurance fund for the same months, and untangling the two systems takes time on both sides.

There are three ways to put such a relationship on a clear footing:

• Make it genuinely independent. Defined deliverables, freedom over time and method, no line management, the right to work for others. This suits project work, not a permanent team role.
• Employ the person yourself. Through your own Belgian company, or by registering as a foreign employer with the ONSS and running Belgian payroll. Cost and timing for each path appear in our EOR and SRL comparison.
• Use an employer of record. Here the EOR becomes the person’s legal employer under a Belgian contract of employment and files the Dimona, pays ONSS and deducts withholding tax through its own payroll.

Moving someone onto a Belgian employment contract settles their status from that date forward. It does not wipe out exposure for the months already worked as a contractor, so for a long-running arrangement take advice on the past period as well. Seniority is a related point: if the relationship is later found to have been employment all along, notice may be counted from the first freelance invoice rather than the date of the new contract.

A short check before engaging anyone in Belgium on self-employed terms saves most of the trouble described above.

• Will the person work mainly or only for you, full-time, for an open-ended period? If so, employment is the natural fit.
• Will you set their hours, approve their leave or put them in a reporting line? Those are the marks of hierarchical control.
• Is the activity in one of the seven presumption areas, including platform work?
• Does the agreement describe deliverables and price them, or does it describe a job and pay a monthly fee?
• Would you be comfortable asking the Administrative Commission for a decision on the arrangement as drafted?

If several answers point towards employment, a Belgian employment contract is the cleaner route. What that contract must contain, from written terms to work regulations, is covered in our article on Belgian contract rules, and our overview of the EOR model sets out what Employer of Record Belgium takes on as the legal employer.
