3. Local Laws Overview
Luxembourg relies on several core texts to govern bookkeeping, auditing and financial reporting. Here are two to three key references with their practical focus:
- Code de commerce (Luxembourg) - Sets out general rules for commercial activity, bookkeeping requirements and the preparation of annual accounts. It provides the legal basis for the obligation to keep proper books and to present financial statements.
- Loi relative à la révision des comptes et à l'audit légal des comptes annuels et consolidés - Establishes the framework for the statutory audit, including when an audit is required and the duties of a réviseur d'entreprises agréé.
- Plan Comptable Luxembourgeois (PCL) - Defines the chart of accounts used by most Luxembourg entities and sets the classification and presentation norms for financial statements; many groups adopt IFRS only for consolidated accounts.
Recent developments in Luxembourg accounting practice have focused on aligning national rules with EU directives and enhancing electronic filing and archiving for corporate accounts. For precise text, dates, and amendments, consult Legilux and Guichet public for the current versions of these laws.

4. Frequently Asked Questions
What is a réviseur d'entreprises agréé and when is one required?
A réviseur d'entreprises agréé is a licensed auditor authorized to conduct statutory audits. They are required for certain larger or listed entities and for specific types of companies under Luxembourg law. Smaller private firms may not be obligated to audit annually, but must keep proper books and be ready for review.
How do I know if my Luxembourg company must use IFRS or Lux GAAP?
Luxembourg generally requires Lux GAAP for most small and medium enterprises, with IFRS used for consolidated accounts of larger groups or listed companies. The choice depends on the legal form and whether accounts are filed as standalone or as part of a group.
When do annual accounts need to be filed with the Registre de Commerce et des Sociétés?
Annual accounts are typically approved at a general meeting and then filed with the RCS. Deadlines vary by company type and size, so consult Legilux or your auditor for the exact timing.
How much does it cost to hire a Buchhalter or auditor in Luxembourg?
Fees vary with complexity, company size and scope of the engagement. A small private company might pay a few thousand euros for a basic audit, while larger groups could exceed ten thousand euros. Obtain a formal engagement letter with a fixed or hourly fee estimate.
Do I need to hire a Luxembourg-based auditor for a small company?
Not always. Small private companies may be exempt from an annual audit, but they still must maintain proper books and file accurate accounts. An auditor can help prepare accounts and ensure compliance if the thresholds are met.
What is the difference between an accountant and a licensed auditor in Luxembourg?
An accountant handles bookkeeping and preparation of financial statements. A licensed auditor, or réviseur d'entreprises agréé, conducts statutory audits and provides assurance on the accuracy of financial statements.
How long does an audit typically take in Luxembourg?
For a small company, the audit may take 2-4 weeks once information is readily available. Larger groups with complex structures can require 6-12 weeks, depending on data completeness and cooperation.
Is it possible to represent clients in front of tax authorities about accounting matters?
Yes, with proper authorization, accounting professionals and lawyers can liaison with the tax administration on behalf of clients. A power of attorney or engagement letter is often required.
What are the consequences of non-compliance with Luxembourg accounting rules?
Penalties can include fines, penalties for late filings and, in severe cases, orders to conduct an independent audit or corrective actions. Managers can bear civil liability for misstatements or negligence.
How should I compare two auditing firms for a small business?
Compare licensing status, scope of services, references, independence, and language capabilities. Request a written proposal outlining deliverables, timelines, and total costs before engagement.
Can I file annual accounts electronically in Luxembourg?
Yes, filings to the Registre de Commerce et des Sociétés can be submitted electronically via official portals. Ensure your accounts are in the correct format and supported by the required certificates if applicable.
Should I consider outsourcing bookkeeping for cross-border operations?
Outsourcing can improve consistency and compliance for cross-border activities. Choose a service with Luxembourg registration, IFRS experience, and knowledge of cross-border VAT and transfer pricing rules.
