Bookkeeping is mandatory for companies in Luxembourg due to several key reasons, as outlined by the country's legal framework:

  1. Legal Compliance: Luxembourg's commercial law, specifically Article 12 of the Commercial Code, mandates that all companies must maintain accurate and detailed financial records. This ensures transparency and accountability in business operations.
  2. Tax Obligations: According to the General Tax Law (Loi générale des impôts), businesses are required to keep proper bookkeeping records to facilitate accurate tax reporting. This helps in preparing and filing tax returns accurately and on time, thereby avoiding penalties and fines.
  3. Financial Management: Bookkeeping provides a clear picture of a company's financial health. It allows businesses to track income, expenses, and profitability, facilitating informed decision-making and strategic planning.
  4. Audit Requirements: Under the Law of 19 December 2002 on the Trade and Companies Register and the Accounting and Annual Accounts of Undertakings, certain types of companies, particularly larger ones, are subject to regular audits. Detailed and accurate bookkeeping is crucial for auditors to verify financial statements and ensure they reflect the true financial position of the company.
  5. Investor Confidence: Maintaining thorough financial records builds trust with investors and stakeholders. It demonstrates good governance and financial stability, making the company more attractive to potential investors and partners.
  6. Risk Management: Proper bookkeeping helps in identifying financial discrepancies, fraud, or errors early. This enables businesses to address issues promptly, safeguarding their financial integrity.
In summary, bookkeeping is mandatory in Luxembourg to ensure legal compliance, accurate tax reporting, effective financial management, audit readiness, investor confidence, and robust risk management, as per the relevant articles of the Luxembourg Commercial Code and General Tax Law.
