Company in Belgium: Key Issues, Registration and Business Operations

Belgium occupies a strategically central position in the European Union, hosting the EU's principal institutions and serving as a logistics and commercial hub for Western Europe. Establishing a company in Belgium gives international businesses direct access to the EU single market, a sophisticated legal framework, and a well-developed financial infrastructure. The core legal instrument governing Belgian companies is the Code des sociétés et des associations (Companies and Associations Code, hereinafter the CSA), which entered into force in stages from 2019 onwards and fundamentally modernised Belgian corporate law. This article walks through the key decisions an international entrepreneur must make - from choosing the right legal form to managing day-to-day compliance - and identifies the practical risks that most commonly affect foreign-owned businesses operating in Belgium.

The CSA introduced a rationalised menu of corporate forms. For most commercial purposes, international investors choose between two primary vehicles: the Besloten Vennootschap / Société à Responsabilité Limitée (BV/SRL, private limited company) and the Naamloze Vennootschap / Société Anonyme (NV/SA, public limited company). A third option, the Coöperatieve Vennootschap / Société Coopérative (CV/SC, cooperative company), is available but reserved by the CSA for entities with a genuine cooperative purpose.

The BV/SRL is the default choice for most new ventures. Under Article 5:1 of the CSA, a BV/SRL can be formed by a single founder, requires no statutory minimum share capital, and offers flexible governance. Shareholders' liability is limited to their contribution. The absence of a minimum capital requirement does not mean capital is irrelevant: founders must prepare a financial plan demonstrating that the company has sufficient resources for at least two years of projected activity. If the company becomes insolvent within three years of incorporation and the financial plan was manifestly inadequate, founders face personal liability under Article 5:16 of the CSA.

The NV/SA suits larger operations, companies intending to list on a regulated market, or structures where transferable shares and a supervisory board are commercially necessary. It requires a minimum subscribed capital of EUR 61,500, of which at least EUR 61,500 must be fully paid up at incorporation. The NV/SA also permits a dual-board structure (board of directors plus supervisory board) under Article 7:85 of the CSA, which aligns with governance expectations in certain industries and for institutional investors.

A common mistake among international clients is defaulting to the NV/SA because it resembles the public limited company they know from their home jurisdiction. In practice, the BV/SRL offers greater contractual freedom, lower formation costs, and simpler ongoing administration for most private commercial operations. The NV/SA imposes stricter rules on share transfers, capital maintenance, and financial reporting that add administrative burden without corresponding benefit unless the business genuinely requires them.

For businesses testing the Belgian market before committing to a full subsidiary, a branch office (bijkantoor / succursale) is an alternative. A branch is not a separate legal entity: the foreign parent bears unlimited liability for branch obligations. Branches must register with the Crossroads Bank for Enterprises (CBE) and file annual accounts in Belgium. They are subject to Belgian corporate income tax on profits attributable to Belgian activities. The branch route is faster to establish but creates direct exposure of the parent's assets, which is a non-obvious risk that many foreign groups underestimate.

Incorporating a Belgian company involves a sequence of formal steps, each with its own procedural requirements. Understanding the sequence prevents delays that can run to several weeks if documents are submitted out of order.

The first step is opening a blocked bank account in the name of the company being formed. The founders deposit the initial capital contribution into this account. The bank issues a certificate confirming the deposit, which is a mandatory exhibit to the notarial deed of incorporation. For a BV/SRL with no minimum capital requirement, the deposit amount must nonetheless correspond to what the financial plan identifies as necessary for the first two years.

The second step is drafting and executing the deed of incorporation before a Belgian notary (notaris / notaire). The notary verifies the identity of founders, reviews the financial plan, and ensures the articles of association comply with the CSA. The notarial deed must include the items listed in Article 5:12 of the CSA: the corporate name, registered office address, purpose clause, share structure, governance rules, and identity of the first directors. Notarial fees are set by royal decree and vary with the amount of capital contributed; for a standard BV/SRL, total notarial costs typically fall in the low thousands of euros.

The third step is registration with the CBE. The notary files the deed electronically through the e-notariat platform, and the CBE assigns a unique enterprise number (ondernemingsnummer / numéro d'entreprise). This number serves as the company's identifier for all interactions with public authorities. The CBE registration is completed within one to three business days of the notarial filing.

The fourth step is VAT registration, which is handled separately through the Belgian tax authority (FOD Financiën / SPF Finances). A company that will make taxable supplies in Belgium must register for VAT before commencing operations. The VAT registration process typically takes two to four weeks. Companies with intra-EU transactions must also obtain an EU VAT number, which is issued as part of the same process.

The fifth step is social security registration. If the company will employ staff, it must register with the National Social Security Office (RSZ / ONSS) before the first employee starts work. Directors who are self-employed must register with a social insurance fund (sociaal verzekeringsfonds / caisse d'assurances sociales) within 90 days of taking up their mandate.

From notarial deed to a fully operational company with enterprise number, VAT number, and social security registration, the realistic timeline is three to six weeks. Delays most commonly arise from incomplete financial plans, identity verification issues for non-EU founders, or slow bank processing of the blocked account certificate. International clients who underestimate these lead times and commit to commercial launch dates before completing registration create avoidable contractual exposure.

The CSA introduced a more flexible governance framework than its predecessor, but flexibility comes with conditions. Understanding the default rules and where they can be modified by the articles of association is essential for structuring a Belgian company that works as intended.

In a BV/SRL, management is entrusted to one or more directors (bestuurders / administrateurs). There is no statutory requirement for a supervisory board, though the articles may create one. Directors are appointed and removed by the general meeting of shareholders. Under Article 5:70 of the CSA, the articles may grant a specific shareholder the right to nominate one or more directors, which is a useful tool for joint ventures where each party wants board representation.

Directors owe duties of care and loyalty to the company. The standard of care is that of a normally prudent and diligent person in the same circumstances, assessed objectively. Directors who breach this standard face personal liability to the company and, in certain circumstances, to third parties. The CSA introduced a liability cap for directors of smaller companies: under Article 2:57, the maximum liability for a single act or series of related acts is capped at a sliding scale based on the company's average turnover and balance sheet total, with a floor of EUR 125,000 and a ceiling of EUR 12,000,000. This cap does not apply to fraud, intentional misconduct, or certain tax and social security obligations.

Shareholder rights in a BV/SRL are more contractually flexible than in an NV/SA. The articles may create different classes of shares with different voting rights, profit entitlements, or liquidation preferences. Under Article 5:48 of the CSA, shares without voting rights are permitted, as are shares with multiple voting rights. This flexibility is valuable for structuring founder-investor relationships, management incentive plans, or family succession arrangements.

The general meeting of shareholders must be held at least once a year to approve the annual accounts. For a BV/SRL, the meeting must take place within six months of the financial year end. Resolutions on ordinary matters require a simple majority. Amendments to the articles of association require a special majority: at least 75% of votes cast, with a quorum of at least 50% of shares present or represented at first call under Article 5:98 of the CSA.

A non-obvious risk for foreign-controlled Belgian companies is the conflict of interest procedure. Under Article 5:76 of the CSA, a director who has a direct or indirect financial interest conflicting with a decision must declare the conflict, abstain from deliberation and voting, and ensure the declaration is recorded in the board minutes. Failure to follow this procedure can result in the decision being voided and the director being held personally liable. International groups that use Belgian subsidiaries as counterparties in intra-group transactions frequently overlook this requirement.

Belgian companies are subject to a tiered financial reporting regime based on size. The thresholds and obligations are set out in the CSA and the Royal Decree of 29 April 2019 on annual accounts of non-listed companies.

A company is classified as small if it does not exceed more than one of the following thresholds on an annual basis: annual turnover of EUR 9,000,000, balance sheet total of EUR 4,500,000, or average headcount of 50 employees. Small companies may prepare abbreviated annual accounts and are not required to appoint a statutory auditor. Large companies must prepare full annual accounts and appoint a réviseur d'entreprises / bedrijfsrevisor (statutory auditor) who is a member of the Institut des Réviseurs d'Entreprises / Instituut van de Bedrijfsrevisoren (IRE/IBR).

Annual accounts must be filed with the National Bank of Belgium (NBB) within 30 days of approval by the general meeting, and no later than seven months after the financial year end. Late filing attracts administrative fines and, for persistent non-filers, can trigger dissolution proceedings initiated by the public prosecutor.

Belgian accounting standards (Belgian GAAP) apply to most companies. Companies that are part of a group required to prepare consolidated accounts under IFRS may use IFRS for their Belgian statutory accounts if they meet the conditions set out in Article 3:1 of the CSA. In practice, most Belgian subsidiaries of international groups use Belgian GAAP for statutory purposes and provide IFRS-compliant reporting to their parent separately.

A common mistake is treating the Belgian statutory accounts as a mere formality. Belgian GAAP contains specific rules on asset valuation, provisions, and the treatment of intra-group transactions that differ materially from IFRS. Errors in the statutory accounts can affect the company's distributable reserves, its ability to pay dividends, and its tax position. Belgian corporate income tax is assessed on taxable income derived from the statutory accounts, adjusted for specific tax rules under the Income Tax Code (Wetboek van de Inkomstenbelastingen / Code des impôts sur les revenus, WIB/CIR).

Belgium's corporate tax framework is competitive by EU standards in certain respects but contains structural features that create unexpected costs for international groups unfamiliar with the system.

The standard corporate income tax rate is 25%. A reduced rate of 20% applies to the first EUR 100,000 of taxable profit for qualifying small companies, subject to conditions including a minimum remuneration requirement for at least one director under Article 215 of the WIB/CIR. The minimum remuneration threshold is EUR 45,000 per year or an amount equal to the company's taxable income if lower. Companies that fail to pay this minimum remuneration face a surcharge of 5.1% on the shortfall, which is a non-obvious cost that catches many owner-managed businesses.

Belgium operates a notional interest deduction (aftrek voor risicokapitaal / déduction pour capital à risque, NID) system under Article 205bis of the WIB/CIR. The NID allows companies to deduct a notional return on their adjusted equity from taxable income. The deduction rate is set annually by royal decree and has been modest in recent years, but the system remains relevant for capital-intensive businesses and holding structures.

The participation exemption (definitief belaste inkomsten / revenus définitivement taxés, DBI/RDT) under Article 202 of the WIB/CIR exempts 100% of qualifying dividends received from subsidiaries, subject to a minimum 10% participation or acquisition cost of EUR 2,500,000, a one-year holding period, and a subject-to-tax condition at the subsidiary level. Belgium is consequently a popular holding location for EU groups, though the subject-to-tax condition and anti-abuse rules under Article 344 of the WIB/CIR must be carefully assessed.

Transfer pricing is a significant compliance area. Belgium adopted the OECD Transfer Pricing Guidelines by reference and requires large companies to prepare a local file, master file, and country-by-country report under Article 321/1 of the WIB/CIR. The Belgian tax authority (FOD Financiën) has increased transfer pricing audit activity in recent years, focusing on intra-group service fees, royalties, and financing arrangements. Companies that rely on informal intra-group pricing without contemporaneous documentation face adjustment risk and penalties.

VAT compliance in Belgium involves monthly or quarterly returns depending on turnover. The standard VAT rate is 21%, with reduced rates of 12% and 6% applying to specific categories of goods and services. Belgium introduced mandatory e-invoicing for B2B transactions between Belgian VAT-registered entities, with a phased implementation schedule. Companies that have not adapted their invoicing systems to the e-invoicing requirements face rejection of invoices and potential VAT deduction issues.

A practical scenario: a US-based technology group establishes a Belgian BV/SRL as its EU hub, licensing intellectual property from a US parent and providing services to EU customers. The Belgian company pays a royalty to the US parent. Without a transfer pricing study and advance pricing agreement with the Belgian tax authority, the royalty rate is exposed to challenge. The Belgian tax authority may disallow part of the royalty deduction, increasing taxable profit and generating interest and penalties on the underpayment. The cost of a transfer pricing study is modest compared to the potential adjustment.

A second scenario: a Belgian family business converts from an NV/SA to a BV/SRL to take advantage of the flexible share structure for a management buyout. The conversion requires a notarial deed, a special majority shareholder vote, and a creditor protection procedure under Article 5:153 of the CSA. Creditors who can demonstrate their claim is at risk may require security before the conversion takes effect. Failing to notify creditors correctly can expose the directors to personal liability.

A third scenario: a non-EU entrepreneur incorporates a Belgian BV/SRL remotely using a power of attorney. The notary requires apostilled identity documents and a certified translation if the documents are not in Dutch, French, or German. Delays in obtaining apostilles from the entrepreneur's home country push back the incorporation date, creating a gap between the intended and actual start of operations.

Belgium has one of the most regulated employment environments in the EU. The legal framework is layered: the Act of 3 July 1978 on employment contracts (Wet betreffende de arbeidsovereenkomsten / Loi relative aux contrats de travail) governs individual employment relationships, while collective labour agreements (collectieve arbeidsovereenkomsten / conventions collectives de travail, CAO/CCT) negotiated at sector and company level add further obligations.

Every Belgian employer must determine which Joint Committee (Paritair Comité / Paritair Comité, PC) covers its activities. Joint Committees are bipartite bodies that negotiate sector-level CAOs covering minimum wages, working time, end-of-year bonuses, and other conditions. The applicable PC is determined by the company's primary activity. Misclassifying the applicable PC is a common mistake that leads to underpayment of sector minimum wages and retroactive social security contributions.

Employment contracts in Belgium must be in writing and in the language of the region where the employee works: Dutch in Flanders, French in Wallonia, and either language in Brussels (with specific rules for cross-border situations). Using the wrong language renders the contract voidable at the employee's option, which can create significant uncertainty in a dismissal context.

Notice periods for dismissal are calculated under the formula introduced by the Act of 26 December 2013 (the Eenheidsstatuut / Statut unique), which unified the previously separate regimes for blue-collar and white-collar workers. The notice period depends on the employee's seniority and is expressed in weeks. For an employee with five years of seniority, the notice period is 13 weeks. For an employee with ten years of seniority, it is 26 weeks. Employers who dismiss without giving proper notice must pay a severance indemnity equal to the remuneration for the notice period.

Belgium's social security contribution rates are among the highest in the EU. Employer contributions are approximately 25% of gross salary (subject to reductions for certain categories of workers), and employee contributions are approximately 13.07%. The total employment cost for a mid-level manager earning EUR 60,000 gross per year is substantially higher than the gross salary figure suggests. International companies that budget based on gross salary alone systematically underestimate their Belgian payroll costs.

The risk of inaction on employment compliance is acute. The Belgian Social Inspection (Sociale Inspectie / Inspection sociale) conducts unannounced audits and has broad investigative powers. Employers found to have misclassified workers, failed to register employees with the RSZ/ONSS, or violated working time rules face administrative fines and, in serious cases, criminal prosecution of the responsible directors. The statute of limitations for social security offences is five years, meaning historical non-compliance can surface long after the fact.

What are the main risks of using a Belgian branch instead of a subsidiary?

A Belgian branch is not a separate legal entity, so the foreign parent company bears direct and unlimited liability for all obligations incurred by the branch in Belgium. This includes contractual debts, tax liabilities, and employment claims. If the branch becomes insolvent, creditors can pursue the parent's assets in any jurisdiction where those assets are located. By contrast, a BV/SRL subsidiary limits the parent's exposure to its capital contribution, subject to the financial plan liability rule for the first three years. For most commercial operations, the subsidiary structure provides materially better asset protection, even though it involves higher formation costs and more ongoing administrative obligations.

How long does it realistically take to set up a Belgian company and what does it cost?

The realistic timeline from initial preparation to a fully operational company is three to six weeks. The main variables are the speed of the blocked bank account opening, the availability of the notary, and the processing time for VAT registration. Formation costs include notarial fees (typically in the low thousands of euros for a standard BV/SRL), CBE registration fees, and professional fees for drafting the financial plan and articles of association. Ongoing annual costs include accounting fees, statutory audit fees if the company is large, and filing fees with the NBB. Companies that engage a Belgian lawyer and accountant from the outset typically complete the process faster and avoid the rework costs associated with deficient financial plans or incorrectly drafted articles.

When should a Belgian company consider restructuring its legal form or governance structure?

Restructuring becomes relevant when the original structure no longer matches the company's commercial reality. Common triggers include bringing in an external investor who requires preferred shares or enhanced information rights, preparing for a management buyout that requires a new share class, or growing to a size where the NV/SA's governance framework becomes commercially appropriate. The CSA provides conversion procedures that allow a BV/SRL to convert to an NV/SA and vice versa without liquidation, but the process requires a notarial deed, a special majority vote, and creditor notification. Early legal advice on governance design at incorporation reduces the need for costly restructuring later.

Belgium offers a well-structured, EU-compliant legal environment for international businesses. The CSA provides genuine flexibility in corporate design, particularly through the BV/SRL form. The tax framework contains useful features for holding and IP structures. The employment and social security regime, however, demands careful planning and ongoing compliance. The most common source of difficulty for international clients is not the complexity of any single rule but the interaction between corporate, tax, and employment obligations that must be managed simultaneously from the moment of incorporation.
