The first decisive choice for yourbusiness start-up costsconcerns the legal form. This decision directly impacts your initial budget, with differences that can reach several thousand euros. Understanding these differences will allow you to optimize your investment from the start.

The sole proprietorship: starting with less than €200 in your pocket

For entrepreneurs wishing to minimize their costs, the sole proprietorship representsthe most economical solution. The total budget is less than €200: registration with the Banque-Carrefour des Entreprises (BCE) costs €109 fixed, to which is added €72 to €82 for the activation of your VAT number via an approved business counter.

The procedures remain simplified and quick. You can even save VAT activation fees by making the request directly to the FPS Finances via online form 604A. This approach nevertheless has significant limitations:unlimited liability on your personal assets, difficulty in raising funds and less professional image with certain commercial partners.

The SRL: an investment of €1,350 to €2,700 to protect your assets

The Limited Liability Company (SRL) requires a significantly larger budget. THEnotary fees range between €750 and €1,100excluding VAT depending on the complexity of your statuses. Mandatory publication in the Belgian Official Gazette adds €222.76 in electronic version or €275.76 in paper version (updated prices for 2024). Registration fees are €95 plus 21% VAT.

In total, plan on between €2,500 and €3,000 including professional support. An entrepreneur creating an e-commerce SRL in Brussels with standard statutes and a simple financial plan will pay around €2,400: €900 in notary fees, €222.76 for electronic publication, €115 in registration fees and €800 for the mandatory financial plan.

Please note:In the event of a contribution in kind (equipment, vehicle, stock, etc.), you must include the costs of a company auditor’s report. This additional cost, often forgotten in forecast budgets, varies depending on the complexity of the file and can represent between €500 and €2,000 additional.

SA: reserved for ambitious projects with minimum €61,500

The Société Anonyme imposes aminimum capital of €61,500, fully releasable upon incorporation. The creation costs remain similar to the SRL, but this legal form is only justified for projects requiring significant fundraising or a future stock market listing.

Accurately calculate mandatory business start-up costs

Beyond the choice of legal form, several mandatory costs are imposed on any entrepreneur. Rigorous planning of these expenses will help you avoid budget overruns.

New notary rates: up to €500 in savings since 2023

The tariff reform of January 1, 2023 considerably reduced thebusiness start-up costsat the notary. The new scale sets the fees at €200 plus a fixed price of €275, generating an average saving of €500 compared to the old rates (around €1,500 previously compared to €1,000 currently according to the official scales).

These amounts include the drafting of the statutes, legal verifications and filing with the registry. Additional services such as the drafting of shareholder agreements or complex clauses entail additional costs.Always negotiate a global quoteincluding all the services necessary for your project.

Incompressible administrative costs: €436 minimum

Some costs remain fixed regardless of your situation. Registration with the ECB costs uniformly€109 for all legal forms. This amount, indexed annually, was €88.50 a few years ago.

Publication in the Belgian Official Gazette represents a significant expense. Systematically opt forelectronic version at €222.76rather than the paper version at €275.76, thus saving €53. The registration fees of €95 plus VAT remain obligatory for all companies.

The financial plan, a mandatory document for companies, costs between €500 and €1,500 depending on its complexity. A basic plan for a service activity can be negotiated at €500 with certain providers like Billy, while a complex industrial project will require a larger investment.

Practical advice:Don’t forget to budget for licenses and authorizations specific to your activity (drinking license, AFSCA authorization for food, transport approval, etc.). These variable costs, rarely included in the basic incorporation costs, can represent several hundred or even thousands of euros depending on your sector of activity.

Activation and compliance: possible savings

Activation of your VAT number can be donefree livewith the FPS Finances, saving you the €72 to €82 charged by business counters. This process simply requires completing Form 604A online.

• Opening a professional bank account: from free with CBC Business Pure Online (Mastercard Prepaid Business included, limited to 1 administrator) to €133.94 excluding VAT/year for complete CBC Business. Intermediate plans include Business One at €42.95 and Business Confort at €66.42 excluding VAT/year
• Compulsory affiliation with a social insurance fund: choose Acerta with its management fees at 3.05% rather than Partena at 4.20%, generating a significant annual saving on your social contributions
• Professional liability insurance: variable depending on your activity

Anticipate hidden costs and optimize your business creation budget

Post-creation costs often represent an unpleasant surprise for poorly prepared entrepreneurs. These recurring expenses can quickly eat up your growing cash flow.

The essential operating costs in the first year

Mandatory accounting for an SRL representsbetween €2,500 and €3,000 per year, or around €205 monthly minimum. This budget includes bookkeeping, VAT declarations and the preparation of annual accounts.

Quarterly social security contributions amount to€907.45 for a main independent(calculated on a fixed income of €17,008.88 for 2025, with regularization based on your actual income communicated 2 years later). First-timers benefit from a reduction of €468.61 for the first four quarters, representing a saving of €1,755 over the first year. For entrepreneurs with income below €1,722.69, a reduction request allows contributions to be reduced to only €100.49 per quarter. The annual publication of your accounts with the National Bank costs an additional €55.

Concrete example:Sophie launches her activity as a digital marketing consultant in Brussels. With income estimated at €1,500 per month in the first year, she requests low-income status and only pays €100.49 in social security contributions per quarter instead of €907.45. She chooses Acerta as her social insurance fund (3.05% fees) and opens a free CBC Business Pure Online account. Its total savings: more than €3,200 over the first year compared to standard choices.
