Starting a business in Belgium has never attracted so many candidates. In 2025, the country recorded a record 128,147 new businesses. This figure hides a more contrasting reality: net growth (startups minus closures) has fallen to less than 1%, its lowest level in the last decade. Embarking on the entrepreneurial adventure in Belgium therefore requires more than just a good idea. Here are concrete benchmarks for building a solid project.
Individual or company: a structural choice often underestimated
Before thinking about a logo or website, the first decision impacts your personal assets. In Belgium, the majority of new entrepreneurs choose the status of individual. This trend has strengthened in recent years, while the creation of companies has declined.
Why this shift? A business as an individual (self-employed in their own name) is quicker to create and less costly to start. No notarial deed, no capital to deposit. However, your liability is unlimited: in case of debt, your personal assets can be seized.
The SRL (limited liability company), on the other hand, separates your private assets from those of the business. It is better suited for activities that involve significant investments or financial risks. Many starters who began as individuals migrate to a company after one or two years of activity, once their model is validated. The choice therefore depends on the nature of the risk, not the volume of ambition.
Platforms like Oser Entreprendre ! allow you to explore the journeys of entrepreneurs who have navigated these choices, helping to move beyond pure legal theory.
Social contributions and Belgian taxation: what starters discover too late
Affiliation to a social insurance fund is mandatory from the first day of activity. This point is known. What is less known is the mechanism of provisional contributions.
At the start of your activity, you pay contributions calculated on an estimated income. Three years later, the administration recalculates based on your actual income. If your activity has gone well, the adjustment can represent several thousand euros in one go. This delay catches many young self-employed individuals off guard.
How to protect yourself from this? Set aside a fixed percentage of your turnover each month to cover this future adjustment. Your accountant can also request to raise your provisional contributions from the first year if your activity exceeds the initial estimates.
Tax reform and electronic invoicing
Belgium is gradually imposing mandatory electronic invoicing between businesses, with a generalization planned for 2026. Specifically, invoices will need to be transmitted in a structured format (such as Peppol), rather than as a simple PDF sent by email.
For a starter, this means choosing a compatible management software from the outset. Delaying this compliance creates a risk of invoice rejection by your professional clients.
Funding the entrepreneurial project: beyond the classic bank loan
You may have noticed that guides for entrepreneurs systematically mention aids and subsidies, without specifying which ones are actually accessible to a starter? Here’s a more concrete framing.
In Wallonia, the dynamics of business creation are booming. The regional support mechanisms are numerous, but access depends on specific criteria: sector of activity, location, project size. Each Belgian region (Wallonia, Brussels, Flanders) manages its own aids, with different conditions and timelines.
- Business vouchers in Wallonia cover part of the consulting, training, or coaching costs for starters. The amount and intervention rate vary depending on the type of voucher requested.
- In Brussels, structures like hub.brussels offer free support and guide towards funding suited to the project’s stage.
- Microcredit, through specialized organizations, remains an option for project holders who do not have access to traditional bank credit (job seekers, people without personal contribution).
Before applying for a subsidy, always check the submission deadline and the required documents. An incomplete file is systematically rejected, with no possibility of recovery in most cases.
Testing your activity without quitting everything: the self-employed internship
Leaving a salaried job to start a business represents a leap that not everyone can afford. Belgium offers a little-publicized mechanism: the transition internship towards self-employment.
This mechanism allows a job seeker to test their entrepreneurial project for several months while retaining their unemployment benefits. The goal is to validate the viability of the activity before fully committing.
- The candidate must submit a simplified business plan to an accredited support organization.
- During the internship, the income generated by the activity is partially cumulative with the benefits.
- At the end of the period, the entrepreneur decides whether to continue as self-employed or resume their job search.
This mechanism significantly reduces the financial risk of starting up. It is particularly suitable for service or freelance projects, where fixed launch costs remain moderate.
Net growth in decline: what this means for a new project
The record number of startups masks a worrying phenomenon. The number of entrepreneurs who cease their activity is increasing in parallel. The net growth of the Belgian entrepreneurial fabric is at its lowest in ten years.
For a future entrepreneur, this data is not discouraging in itself, but it imposes a requirement: the project must be viable from the first months. Market conditions do not forgive a sloppy launch. Validating your offer with real clients before investing, limiting fixed costs at the start, planning a safety cash flow for the first six months of activity: these reflexes separate sustainable projects from closure statistics.
Belgium remains fertile ground for entrepreneurship, with solid support tools in Wallonia as well as Brussels. The journey simply requires treating each administrative and financial step as an investment, not a formality.
