How to Become a Freelancer in Belgium: Transition Checklist

Leaving salaried employment to become a freelancer is a major decision. In Belgium, this transition involves specific legal, tax, social and financial aspects that you must master before making the leap. This guide walks you through every step, from your first thoughts to your first invoice, with a detailed checklist and advice suited to the Belgian reality of 2026.

Phase 1: Preparing to Become a Freelancer (3 to 12 Months Before)

1.1 Assess Your Current Situation

Before resigning, do a full review:

Financial review:

Review of fringe benefits to replace:

In Belgium, an IT employee's salary package often includes substantial benefits that you will have to fund yourself once you become a freelancer:

Conclusion: to maintain the same standard of living, your freelance revenue must cover not only your former net salary, but also the value of all these benefits. As a rule of thumb, an IT freelancer must bill at least 1.5 to 2 times their former gross salary to reach an equivalent standard of living.

1.2 Test the Market Before You Become a Freelancer

This is the safest and most recommended strategy in Belgium. Self-employed status as a secondary activity (indépendant complémentaire) lets you start a freelance activity while keeping your salaried job.

Conditions for secondary self-employed status:

• Be an employee with an employment contract of at least half-time (Article 35 of the Royal Decree of 19 December 1967)
• Or be a civil servant working at least 200 days or 8 months a year
• Or be a teacher working at least 6/10ths of a full schedule

Advantages of this test phase:

• Reduced social contributions (about EUR 85/quarter minimum if net income is below EUR 1,865.44/year)
• You keep all your social rights as an employee (unemployment, pension, sick pay)
• A real-world test of your ability to find clients
• Gradual building of your network and reputation
• Building up a financial reserve

Points to watch:

• Check your employment contract: is there a non-competition or exclusivity clause?
• Find out your employer's policy on secondary activities
• Do NOT work for your current employer as a freelancer (risk of reclassification)
• Respect your duty of loyalty to your employer (Article 17, §3 of the Law of 3 July 1978)

1.3 Check Your Employment Contract

Before resigning, read your employment contract carefully:

Non-competition clause:

In Belgium, the non-competition clause (Article 65 of the Law of 3 July 1978) is subject to strict conditions:

• It must be in writing
• It can only cover similar activities
• It is limited geographically (to areas where you could genuinely compete with the employer)
• It is limited in time (12 months maximum)
• The employer must pay you compensation (unless the employer ends the contract for serious misconduct, or you resign without a serious reason)
• It only applies if your gross annual pay exceeds a certain threshold (in 2026: around EUR 41,969 gross/year for the ordinary non-competition clause)

If your gross annual pay is below EUR 41,969: the non-competition clause is automatically void.

If your gross annual pay is between EUR 41,969 and EUR 83,939: the clause is only valid for roles defined by a sector-wide collective agreement.

If your gross annual pay exceeds EUR 83,939: the clause can be valid for any role.

Intellectual property clause:

Check whether your contract contains a copyright assignment clause. Under Article XI.169 of the Code of Economic Law, an employer is presumed to hold the economic rights over computer programs created by an employee in the course of their duties. This does not cover work created outside your job duties.

1.4 Build Your Financial Reserve

Minimum target: 6 months of fixed costs plus start-up costs.

Launch budget (estimate):

Phase 2: Resigning to Become a Freelancer (1 to 3 Months Before)

2.1 Notice Periods in Belgium

Since the Single Status Law of 26 December 2013, notice periods have been harmonised for blue-collar and white-collar workers, calculated according to seniority:

Notice starts running on the Monday following the week of notification.

Valid ways to give notice:

• Registered letter (takes effect on the 3rd business day after posting)
• Handing over a signed, dated letter in person (takes effect immediately)
• Bailiff's writ (rare in practice)

2.2 Alternatives to Resigning

Mutual agreement termination:

You and your employer can agree to end the contract by mutual consent, on a date you choose together. This lets you:

• Negotiate your leaving date
• Possibly negotiate a severance payment
• Leave on good terms

Warning: with a mutual agreement termination, you are NOT entitled to unemployment benefits (except after a 4-week waiting period and assessment by ONEM, the National Employment Office).

Negotiated dismissal:

In some cases, you can negotiate your dismissal with your employer. This gives you the right to:

• A notice payment (or working out your notice)
• Unemployment benefits (under conditions)
• The option to combine unemployment benefits with launching your self-employed activity (via the "Tremplin indépendants" back-to-work scheme)

2.3 ONEM's "Tremplin Indépendants" Scheme

This scheme, set out in the Royal Decree of 18 July 2019, lets jobseekers launch a secondary self-employed activity while keeping their unemployment benefits.

Conditions:

• Be a fully unemployed person receiving benefits
• Carry out the self-employed activity as a secondary activity
• Net income from the self-employed activity must not exceed a set threshold (about EUR 4,800/year net in 2026)
• Maximum duration: 12 months
• The application must be submitted BEFORE starting the activity

Advantages:

• You keep your unemployment benefits
• You test your activity with no financial risk
• You build your client portfolio
• After the 12 months, you can switch to self-employed as your main activity

Limits:

• Very low income threshold (EUR 4,800/year net)
• The activity must not have been your main activity in the last 6 months
• Some activities are excluded

2.4 Leave to Start a Business

Belgium has no legal "leave to start a business" as exists in France. However, you can negotiate with your employer:

• Time credit (reduced working hours) via CCT no. 103 of the National Labour Council (CNT), to free up time for your project
• Unpaid leave (no legal basis, but negotiable)
• Temporary part-time work to launch your activity alongside your job

Phase 3: The Paperwork to Become a Freelancer (Weeks 1 to 4)

3.1 Full Administrative Checklist

Week 1: official registrations

• Choose your legal status (sole trader or SRL)
• If SRL: appointment with a notary, drafting the financial plan, opening the blocked account
• Register with an approved enterprise counter (Acerta, Xerius, UCM, Liantis, Partena)
• Obtain your CBE company number

Week 2: affiliations and activations

• Join a social insurance fund
• Activate your VAT number with the VAT control office (FPS Finance)
• Open a separate business bank account
• Choose and appoint an accountant

Week 3: insurance and protection

• Take out professional liability insurance
• Take out individual hospitalisation insurance (replacing your employer's cover)
• Take out guaranteed income insurance (incapacity for work)
• Take out a PCLI contract (voluntary supplementary pension for the self-employed)
• Check your affiliation with a health insurance fund (independent of your employer)

Week 4: tools and commercial launch

• Set up invoicing software (Billit, Teamleader, Facturatie, CashControl)
• Create or update your LinkedIn profile
• Register on freelance platforms (Freelance.be, Malt)
• Prepare your standard service contract
• Prepare your price list
• Order business cards (optional but professional)
• Tell your network about your launch

3.2 Managing the Social Transition

Health insurance fund:

As an employee, your health insurance fund (mutualité) manages your healthcare. Once you become a freelancer, you remain covered by health and disability insurance, but under self-employed status. Inform your fund of your change of status.

Family allowances:

Since regionalisation in 2019, family allowances are managed by:

• Groeipakket (Flanders): via payment funds (FONS, KidsLife, MyFamily, etc.)
• Famiwal (Wallonia)
• Famiris (Brussels)
• Ostbelgien (German-speaking Community)

Moving from employee to self-employed status does not change your entitlement to family allowances.

Pension:

As an employee, your pension is calculated based on your gross pay. As a self-employed person, the statutory pension is calculated on your professional income with a correction factor (harmonisation coefficient). In practice, a self-employed person's pension is usually lower than an employee's for equivalent income.

Recommended action: take out a PCLI now and, if you set up an SRL, an EIP (Individual Pension Commitment) to offset this difference.

Phase 4: Your First Months After You Become a Freelancer (Months 1 to 6)

4.1 Managing Your Finances in the First Months

The first months are financially critical. Here is a calendar of deadlines to plan for:

4.2 Setting Your Starting Day Rate

For your first assignment, you may need to accept a day rate slightly below market rate to build your freelance track record. But never go below your break-even threshold.

Quick calculation of your minimum survival day rate:

Minimum day rate = (fixed monthly costs x 12 + estimated tax + social contributions) / billable days

Example:
- Fixed costs: EUR 3,500/month = EUR 42,000/year
- Social contributions: EUR 12,000/year
- Estimated tax: EUR 15,000/year
- Billable days: 165 days/year

Minimum day rate = (42,000 + 12,000 + 15,000) / 165 = EUR 418/day

Launch strategy:

• Months 1-6: day rate at 90% of market rate to build references
• Months 6-12: day rate at market rate
• Year 2+: market rate plus an annual increase

4.3 Building Your Reputation

The first 6 months are the time to lay the groundwork for your reputation:

• Overdeliver on your first assignment: flawless quality, proactivity, regular communication
• Ask for a LinkedIn recommendation from your first client as soon as the assignment ends
• Document your results: impact metrics, before/after, testimonials
• Publish content: one technical article a month on LinkedIn or your blog
• Attend meetups: introduce yourself, network, hand out your contact details

Phase 5: Pitfalls to Avoid When You Become a Freelancer

5.1 Financial Mistakes

1. Not setting money aside for tax and contributions: from the first euro you earn, put 40 to 50% aside in a separate account
2. Forgetting advance tax payments: the 9% surcharge (2026) is an avoidable penalty
3. Underestimating the social contribution adjustment: in the first years, your contributions are provisional and based on a flat rate. The adjustment happens 2-3 years later, based on your actual income. If your income was high, the adjustment can be painful
4. Spending before you're paid: the legal payment term in Belgium is 30 days, but some clients pay at 60 or even 90 days

5.2 Legal Mistakes

1. Working without a written contract: even for a "small" project
2. Ignoring the non-competition clause from your former employment contract
3. Working exclusively for your former employer: risk of being reclassified as a false self-employed worker
4. Not taking out professional liability insurance: a production bug can cost hundreds of thousands of euros

5.3 Strategic Mistakes

1. Resigning without a financial reserve: 6 months' worth minimum
2. Resigning without a first client: ideally, have at least one confirmed assignment or one under negotiation
3. Deciding to become a freelancer full-time without testing as a secondary self-employed worker first: the market may be less receptive than you think
4. Neglecting your network: in Belgium, word of mouth and networking account for 30 to 50% of assignments
5. Choosing the wrong legal status: consult an accountant BEFORE you launch
