EU, EEA and Swiss nationals don’t need a card, and neither do some residence statuses. Otherwise, the region of your business’s operating address decides; a Flemish card lets you work across Belgium.
How I went from employee to self-employed: the professional card in Belgium
After a few years as an employee, I wanted to go freelance. As a non-EU national, that meant a professional card. Here’s how I got two of them, what I was asked for that wasn’t on any checklist, and how the rules work today.
My experience plus a summary of the official rules, not legal advice. Amounts and conditions change, and Brussels and Wallonia have their own procedures. Check the official sources at the bottom before you apply.
- What it is: your permission to work as self-employed in Belgium if you’re not an EU, EEA or Swiss national. It’s the self-employed counterpart of a work permit, but you apply for it yourself, not an employer.
- Who decides: the region where your business has its operating address. A Flemish card is also valid in Brussels and Wallonia.
- Two kinds: self-employed as your main occupation, or as a secondary occupation next to a job of at least half-time.
- It’s not a residence permit. Once you have the card, you still update your residence at your commune.
- Timing: a decision within 120 days; the card is valid for one to three years.
How it went for me
I came to Ghent as an employee, working in software. A few years in, I wanted more flexibility, and the chance to work with different companies instead of one. In Belgium, that meant switching from employee to self-employed, and as a non-EU national, that meant a professional card.
While I was still employed, I applied for a professional card for a secondary occupation. Since my job was my main activity and income, I didn’t have to provide many documents.
About two to three weeks later, I had the card and could start freelancing on the side right away.
If you’re still employed, this is a gentle way to test the waters.
This application was a different story. The heart of it is the business plan, and the most important question in it is one nobody spells out: why does your activity need to be in Flanders, rather than anywhere else in Europe?
For me, the answer was tech. Flanders had been investing heavily in its tech and startup scene, and that’s exactly where my expertise was. My advice: follow the news, see which sectors the government cares about, and connect what you bring to that.
I also connected the dots to show I was already part of life here: I’d worked in Belgium, I spoke the local language, and I had a network of local colleagues. The motivation has to sound business-like, but showing you genuinely care about the place helps build your case.
And I described one activity only. If you do marketing consulting and also sell art online, pick one. Imagine being the official reading your file: two activities sounds like you’re not sure what your business is.
I made a three-year projection of my income and expenses, including what I’d spend on an accountant, advisors, equipment and marketing. The point was to show I knew what I was getting into, and how I’d earn enough to sustain myself.
Having an accountant review my plan was nice, but not necessary. Only I knew what my business was about and how I’d run it. If numbers aren’t your thing, though, an accountant can check whether your projections make sense.
After I submitted, I was asked for references or letters of intent. So I collected two letters of intent from potential clients, and two references from colleagues at my former Belgian employer.
Not on the official checklist, but have them ready before you apply.
With the professional card approved, I went to my commune to change my status from employee to self-employed and update my residence. The card gives you the right to work as self-employed; the residence card is a separate step.
My first card was valid for a year. The renewal felt very similar to the first application, except that now my actual results could be compared with what I’d said I would achieve.
If your numbers didn’t turn out as projected, or a client you mentioned didn’t sign, be ready to explain why, honestly, and share your plan B. Everyone knows unexpected things happen; you’re the one who cares most about it, so show you’ve thought about what’s next.
What I brought: emails and letters of intent from my next potential clients, certifications I’d earned during the year, what I’d learned and how I’d improve, and an updated three-year revenue projection, which they asked for, starting from the renewal.
Then the residence part again. This time my commune couldn’t decide on the extension itself, and sent my file to the Immigration Office in Brussels. I had to provide the renewed professional card plus proof of my taxes, social security payments, invoices and VAT. Once it was approved, I made a new appointment to extend my residence.
Two renewals again: the card, and the residence. They’re never quite the same thing.
Looking back, the side-activity card was the easy part. The main card is where you have to think like a business, and argue why you belong here.
How it works now (Flanders, 2026)
The Flemish rules were reformed in 2022 and have been updated since. Here’s the current process.
Your activity must bring economic, innovative, or sporting, cultural or artistic added value to Flanders. You also choose between main occupation and secondary occupation (next to a job of at least half-time).
See the document list below. Everything must be in Dutch, French, German or English; official documents need a sworn translation.
If you already live in Belgium legally, apply through the WSE portal, on a desktop or laptop only. If you live abroad, apply through the Belgian embassy or consulate where you reside.
The region decides within 120 days, which can be extended for complex files. If documents are missing, you get 30 days to complete your file.
The card costs €90 per year of validity, and is valid for one to three years. If you’re in Belgium, take it to your commune to update your residence. From abroad, you first apply for a D visa, then register when you arrive.
Apply for renewal no later than 60 days before your card expires. Any change in your activity, address or status needs an amendment to the card.
Documents for a first application
Required in every case, in Flanders:
- A copy of your passport or foreign identity card
- An extract from your criminal record, less than six months old
- Your diploma, at least secondary-education level
- Proof of stable, regular and sufficient means of subsistence: at least 110% of the living wage
- A full business plan: target market, market size, competitive analysis, SWOT and marketing plan, plus the official financial plan template
- If you already live in Belgium: a copy of your valid residence card (an A card, or an H card if you’re on a Blue Card)
Depending on your situation, you may also need: proof of at least €22,838 in your own account and of job creation or economic benefit (economic category); evidence of innovation or of working with an incubator or research centre (innovative category); company documents if you work through a company; or a valid work permit for your main job (secondary occupation).
What changed since my applications
| When I applied | Now (Flanders) | |
|---|---|---|
| Side-activity card | Few documents; mine came in 2–3 weeks | A valid work permit for a main job of at least half-time; same portal and fees |
| Card validity | One year, then renewal | One to three years, depending on your file |
| Decision time | Weeks to a few months | Within 120 days (can be extended) |
| Income proof | Income at least 120% of the living wage | At least 110% of the living wage; for the economic category, also €22,838 in your own account |
| Renewal | Recommended: start 4–5 months ahead | Officially no later than 60 days before expiry; starting early is still wise |
- Answer the real question: why here? Tie what you do to what the region invests in.
- Pick one activity. Focus reads as confidence.
- Show you’re already part of life here: language, work history, local network.
- Prepare two letters of intent and two references before you submit, even though they’re not on the list.
- Build your plan around three years, with real costs, so the renewal can hold you to something you believe in.
- Start the renewal early. Your residence depends on the card, and the residence step can take longer than you think.
