Becoming an IT Freelancer in Belgium: A Guide for Developers

Belgium's IT sector faces a structural shortage of talent. According to figures from Agoria, the Belgian technology industry federation, more than 30,000 IT positions remain unfilled in 2026. This tight labour market creates extremely favourable conditions for developers who want to go freelance. But where do you start? This guide covers every step of the process, from choosing a legal status to issuing your first invoice.

Why become an IT freelancer in Belgium in 2026?

A booming market

Belgium has positioned itself as a European tech hub. As the capital of the European Union, Brussels concentrates hundreds of institutions and international companies with constant IT needs. The figures speak for themselves:

• Median salary for an employed developer: between EUR 3,200 and 4,500 gross/month, depending on experience (source: Robert Half 2025 salary survey)
• Median day rate for a freelance developer: between EUR 450 and 650/day excl. VAT for an experienced profile
• Potential income gap: a senior freelancer can bill EUR 120,000 to 160,000/year, compared with EUR 55,000 to 75,000 gross/year as a permanent employee

The most in-demand technologies in Belgium

Step 1: Choose your legal status

This is the first crucial decision. In Belgium, you have two main options.

Option A: Sole trader status (entreprise individuelle)

This is the simplest and quickest way to get started.

Advantages:

• Quick start (registration takes just a few days)
• No minimum capital required
• Simplified bookkeeping is possible
• Low start-up costs (around EUR 90 to 100 in registration fees at the enterprise counter)

Disadvantages:

• Unlimited liability against your personal assets
• Taxed under personal income tax (IPP – impôt des personnes physiques), with progressive rates reaching 50% above EUR 46,440 of net taxable income (2027 assessment year, 2026 income)
• Social security contributions calculated on your total net professional income

Personal income tax scale for 2026 income:

On top of these rates, municipal surcharges apply (between 0% and 9% depending on the municipality, generally around 6 to 7%).

Option B: Company (SRL – private limited company)

Since the new Companies and Associations Code (CSA) came into force on 1 May 2019, the SRL has replaced the former SPRL.

Advantages:

• Liability limited to your contribution (your personal assets are protected)
• Corporate tax (ISoc) rate of 25%, reduced to 20% on the first EUR 100,000 of profit for SMEs that meet the conditions
• You can pay yourself a salary (director's remuneration) and dividends
• Tax optimisation through the liquidation reserve (10% tax, with distribution after 5 years subject to a withholding tax of just 5%)
• Broader scope for deducting expenses

Disadvantages:

• A mandatory financial plan (Article 5:4 of the CSA)
• You must keep double-entry bookkeeping
• Formation costs (notarial deed: around EUR 1,000 to 1,500; publication fees in the Belgian Official Gazette: around EUR 230)
• Higher accounting fees (EUR 1,500 to 3,000/year for an accountant)
• A minimum director's remuneration of EUR 45,000/year is required to benefit from the reduced 20% corporate tax rate

Which status should you choose? A rule of thumb

• Net annual income below EUR 45,000: sole trader status is generally more advantageous
• Net annual income between EUR 45,000 and 80,000: consult an accountant, as it depends on your situation
• Net annual income above EUR 80,000: the SRL almost always becomes more tax-efficient

Step 2: Administrative procedures

2.1 Register with an approved enterprise counter

The enterprise counter (guichet d'entreprise) is a mandatory step. It registers you with the Crossroads Bank for Enterprises (BCE) and issues you a company number (a 10-digit CBE number, format 0XXX.XXX.XXX).

Approved enterprise counters in Belgium:

• Acerta (enterprise counter and social insurance fund)
• Xerius (very popular in Flanders)
• Liantis (formerly Zenito + SBB)
• UCM (Union des Classes Moyennes, strong in Wallonia and Brussels)
• Partena Professional
• Formalis (Groupe HD)

Registration cost: around EUR 93.10 (2026 amount) for a sole trader, more for a company.

2.2 Join a social insurance fund

Registration is mandatory within 90 days of starting your activity (Royal Decree of 19 December 1967). You are free to choose your fund.

Social security contributions for the self-employed (2026):

Minimum contribution for a self-employed person in a main occupation (starting out): around EUR 840/quarter (2026).

What social security contributions cover:

• Retirement pension
• Health and disability insurance (healthcare and benefits)
• Child benefit (regionalised since 2019: Groeipakket in Flanders, Famiwal in Wallonia, Famiris in Brussels, Ostbelgien for the German-speaking community)
• Droit passerelle bridging allowance (the self-employed equivalent of unemployment benefit, in case of bankruptcy or forced cessation of activity)

2.3 Activate your VAT number

You must activate your VAT number with the relevant VAT control office (FPS Finance). The Belgian VAT number follows the format BE 0XXX.XXX.XXX (identical to your company number, preceded by "BE").

VAT obligations:

• Periodic VAT returns (monthly or quarterly)
• Standard rate of 21% for IT services
• Reverse charge mechanism for intra-Community B2B services (Article 21(2) of the VAT Code)
• Annual listing of Belgian VAT-registered customers

VAT exemption scheme: if your annual turnover does not exceed EUR 25,000 (a new threshold since 1 January 2025), you can opt for the exemption scheme, which exempts you from charging and declaring VAT. This is of limited relevance for a full-time IT freelancer, but useful when starting out as a secondary activity.

2.4 Open a professional bank account

Since 2020, the law has required every self-employed person to have a professional bank account separate from their personal account (Article III.89 of the Code of Economic Law).

Banks popular with self-employed people in Belgium:

• KBC/CBC: comprehensive SME offerings
• BNP Paribas Fortis: extensive branch network
• Belfius: good digital integration
• ING: tailored Business offering
• Finom, Qonto, Wise Business: neobanks with lower fees, popular with IT freelancers

2.5 Take out the necessary insurance

Mandatory or strongly recommended insurance:

Step 3: Skills and positioning

3.1 Define your niche

The Belgian IT market is broad, but the most successful freelancers are those who specialise. Here are some promising niches for 2026:

• FinTech and banking: Brussels is a European financial centre. BNP Paribas Fortis, KBC, Belfius, Euroclear and Swift (whose global headquarters are in La Hulpe) hire freelancers on a large scale.
• European institutions: the European Commission, Parliament, Council and their agencies outsource huge numbers of IT projects through framework contracts.
• Pharma and biotech: Belgium's pharmaceutical sector (UCB, GSK, Janssen/J&J in Beerse) is a heavy consumer of IT development.
• E-commerce: Belgium is catching up on online retail. Belgian SMEs are investing in their platforms.
• Public sector: FPS Finance (Tax-on-web), Smals (the Belgian state's IT partner) and the healthcare sector (eHealth) offer numerous assignments.

3.2 Certifications valued in the Belgian market

• AWS Certified Solutions Architect / Azure Solutions Architect Expert
• Scrum Master / Product Owner (PSM, CSPO)
• ITIL 4
• TOGAF (for enterprise architecture)
• CISSP / CEH (for cybersecurity)
• PMP / Prince2 (for project management)
• Google Cloud Professional

3.3 Language skills

Belgium is a trilingual country. Language skills are a major asset:

• Brussels: French + Dutch + English (trilingualism is highly valued)
• Flanders: Dutch required + English (French appreciated)
• Wallonia: French + English (Dutch appreciated)
• European institutions: English essential, French very useful

A bilingual FR/NL IT freelancer in Brussels can easily negotiate a day rate 10 to 15% higher than a monolingual profile.

Step 4: Find your first assignments

Prospecting channels in Belgium

Specialist IT platforms:

• Freelance.be: the reference platform in Belgium
• Connect by Smals: assignments for the Belgian public sector
• Hays, Robert Half, Michael Page: recruitment firms with dedicated IT freelance divisions
• Easi, Tobania, Inetum-Realdolmen, Ordina: Belgian IT consulting firms (ESN) that place freelancers

International platforms active in Belgium:

• Malt: very popular for B2B assignments in Belgium and France
• Toptal: for senior profiles
• Upwork: international assignments
• LinkedIn: essential — most IT assignments in Belgium go through LinkedIn

Networking:

• BeJS, Ruby Belgium, AWS User Group Belgium: Belgian tech communities
• BruSSELs Tech Meetups: regular events
• Devoxx Belgium (Antwerp): Europe's leading Java conference
• FOSDEM (Brussels): Europe's largest open-source event

Step 5: Manage your bookkeeping and tax affairs

Bookkeeping obligations

As a sole trader:

• Income and expenditure journal
• Purchase and sales invoice books
• Annual inventory
• Annual personal income tax return (Tax-on-web, generally between May and October)
• VAT returns (quarterly or monthly)

As a company (SRL):

• Double-entry bookkeeping (Belgian standardised minimum chart of accounts – PCMN)
• Annual accounts to be filed with the National Bank of Belgium (BNB) within 7 months of the financial year-end
• Annual corporate tax return
• VAT returns
• Withholding tax returns on remuneration paid

Typical deductible expenses for an IT freelancer

Advance tax payments

As a self-employed person, you must make advance tax payments (versements anticipés) every quarter to avoid a tax surcharge. The deadlines are:

• VA1: 10 April (12% reduction)
• VA2: 10 July (10% reduction)
• VA3: 10 October (8% reduction)
• VA4: 20 December (6% reduction)

Failure to make advance payments results in a 9% surcharge (2026) on the tax due.

Step 6: Protect yourself legally

The service agreement

Every assignment should be governed by a written contract. The essential clauses are:

• A precise description of the assignment and deliverables
• Duration and renewal conditions
• Rate (day rate or fixed fee) and billing terms
• Payment term (30 days maximum in B2B relationships, under the law of 2 August 2002 on late payments)
• An intellectual property clause
• A confidentiality clause (NDA)
• Termination conditions and notice period
• A non-solicitation clause (careful: do not confuse this with an unlawful non-compete clause)

False self-employment: a risk to be aware of

The Programme Act of 27 December 2006 (known as the "law on employment relationships") sets out criteria for distinguishing self-employed workers from employees. The NSSO and NISSE can reclassify a working relationship if:

• You only have a single client
• The client sets your working hours
• You use exclusively the client's equipment
• You are integrated into the client's organisational structure
• You bear no economic risk

The Administrative Commission for the Regulation of the Employment Relationship (CRT) can be consulted in case of doubt. Reclassification can result in the retroactive payment of both employer and employee NSSO contributions.

Conclusion
