Accounting and auditing in Woluwe-Saint-Pierre - Sint-Pieters-Woluwe follow Belgian and European rules. The municipality sits in the bilingual Brussels-Capital Region, so many procedures can be handled in French or Dutch. Companies, non-profits, and independent professionals must keep proper books, prepare annual accounts, and in some cases appoint a statutory auditor. Annual accounts are typically prepared under Belgian GAAP and filed with the National Bank of Belgium through the Central Balance Sheet Office. Listed groups and certain public interest entities follow EU rules on audits and consolidated reporting.
The Companies and Associations Code sets out who must prepare which type of accounts, filing deadlines, and when an auditor is mandatory. Professional accountants and statutory auditors are regulated professions in Belgium. Accountants and tax advisors are supervised by the Institute for Tax Advisors and Accountants, while statutory auditors are members of the Institute of Registered Auditors. In Brussels, language rules and local taxes can influence how and where documents are filed. Getting tailored advice early helps avoid penalties and ensures compliance.
This guide gives a practical overview for businesses and organizations based in Woluwe-Saint-Pierre - Sint-Pieters-Woluwe that need legal clarity on accounting and auditing duties.
You may need a lawyer when choosing the right legal form and setting up your accounting system. The legal form you pick affects the accounting framework, disclosure, and whether an audit will be required. A lawyer can align bylaws, shareholder agreements, and governance with reporting and audit rules.
Legal help is useful when your company grows and crosses thresholds that trigger new obligations. Crossing size thresholds may change the format of accounts, require group consolidation, or make the appointment of a statutory auditor mandatory.
Transactions such as capital increases, contributions in kind, mergers, demergers, or transfers of a business often require special auditor reports and strict procedures. Legal counsel coordinates these steps and the required filings with the Enterprise Court registry and the National Bank of Belgium.
If you receive a tax audit, social inspection, or face late filing penalties, a lawyer can manage communications with authorities, negotiate timelines, and mitigate sanctions. They can also advise on director liability linked to accounting irregularities, wrongful trading, or late filing.
Non-profits and associations face specific rules and thresholds. A lawyer helps confirm whether you must file simplified, abbreviated, or full accounts, and whether a statutory auditor is required. Public interest entities and regulated sectors have additional audit and independence rules that warrant specialist legal support.
In Brussels, language laws, publication requirements, and local taxes may complicate filings. A Brussels-based lawyer ensures documents are in the correct language, that governance meets regional practice, and that publications are valid.
Companies and Associations Code. The Code des sociétés et des associations - Wetboek van vennootschappen en verenigingen governs bookkeeping, annual accounts, management reports, consolidation, and audit appointments for companies and non-profits. It defines micro, small, and large entities based on thresholds for employees, balance sheet total, and turnover. Small entities can use abridged formats. Large entities and public interest entities must have a statutory auditor and file full accounts.
Belgian GAAP and IFRS. Individual statutory accounts are prepared under Belgian GAAP. Listed groups and certain groups prepare consolidated accounts under IFRS. Other groups may choose IFRS for consolidation, but statutory accounts remain Belgian GAAP.
Filing deadlines. The general meeting must approve the annual accounts within six months of financial year end. Accounts must be filed with the National Bank of Belgium within 30 days after approval and no later than seven months after year end. Late filing leads to surcharges and potential sanctions. Directors risk personal liability in case of serious non-compliance.
Audit requirements. A statutory auditor must be appointed if your entity is large, is a public interest entity, or belongs to a regulated sector that requires an audit. Special engagements by a registered auditor are required for contributions in kind, quasi-contributions, mergers, demergers, and certain capital changes. The statutory auditor is the commissaire in Belgian law and must be a registered réviseur d’entreprises - bedrijfsrevisor.
Professional regulation and oversight. Accountants and tax advisors are regulated by the Institute for Tax Advisors and Accountants. Statutory auditors are regulated by the Institute of Registered Auditors and subject to public oversight derived from EU audit rules, including auditor independence, quality control, and rotation for public interest entities.
Language and publication in Brussels. With a registered office in the Brussels-Capital Region, you generally choose French or Dutch for corporate documents and filings. Annual accounts must be filed in French or Dutch. Filings and publications must respect language rules to be valid. Woluwe-Saint-Pierre - Sint-Pieters-Woluwe is bilingual in practice, but you should maintain consistency of the chosen language in official records.
Non-profits. Associations without lucrative purpose and international non-profits have accounting and filing duties aligned with their size. Large and very large non-profits usually file at the National Bank of Belgium and may need a statutory auditor. Smaller non-profits use simplified schemes and file at the Enterprise Court registry.
Tax and VAT interface. Accounting records support Belgian corporate tax and VAT returns. Many businesses file VAT monthly or quarterly. Belgium is introducing structured electronic B2B invoicing. It is prudent to prepare your systems now to comply when it becomes mandatory.
Record retention. Keep accounting books, invoices, and supporting documentation for at least seven years. Longer retention may apply for certain assets such as real estate under VAT adjustments. Data protection rules apply to accounting archives that include personal data.
An auditor is required if your entity is large based on the Code thresholds, if you are a public interest entity such as a listed company, or if a sector law imposes an audit. Some transactions also require a registered auditor for a one-off special report. A lawyer can assess your status and timing for appointment.
The general meeting approves the accounts within six months after year end. Filing at the National Bank of Belgium must occur within 30 days of approval and at the latest seven months after year end. Non-profits follow similar timing, with filing either at the National Bank of Belgium or the Enterprise Court registry depending on size.
No. In Brussels you file annual accounts in French or Dutch. Choose one language and keep it consistent across official documents to comply with language laws.
You face National Bank of Belgium surcharges and potential administrative or criminal fines. Persistent non-compliance can affect director liability, credit ratings, and dealings with banks or suppliers. Prompt corrective filing reduces risk.
No statutory audit is required for freelancers and most micro or small companies, unless a specific law or transaction triggers a special auditor report. They must still keep proper books and file the correct format of annual accounts.
Individual statutory accounts use Belgian GAAP. Certain groups must prepare consolidated accounts under IFRS. Others may choose IFRS for consolidation, but not for statutory accounts. Your advisor can confirm which framework applies to you.
Belgium classifies entities as micro, small, or large based on three criteria relating to average employees, balance sheet total, and turnover. Meeting or exceeding two criteria moves you to the next category and may change audit and filing obligations. Verify the current numerical thresholds for your financial year before filing.
Large and very large non-profits generally file at the National Bank of Belgium and may require a statutory auditor. Smaller non-profits use simplified accounts and usually file at the Enterprise Court registry. A lawyer can confirm your category and the correct filing channel.
Keep books and substantiating documents for at least seven years. Keep some records longer when VAT adjustment periods apply, for example real estate investments. Ensure retention complies with data protection rules for personal data.
Belgium is phasing in structured electronic B2B invoicing. Many public sector bodies already require e-invoices. Businesses should prepare their accounting systems to issue and receive structured e-invoices ahead of the nationwide mandate.
