Guidance for making decisions

Understand a concept, then know what to do

Creating and managing a business in Luxembourg requires understanding the documents you sign, the figures in your accounts and the formalities to be completed. This glossary links accounting, tax, social security and legal terms to their practical consequences: what they refer to, the important distinctions and the checks to prepare.

Each listing provides an educational example, related terms, and application guides and official sources. You can thus move from a definition to a procedure, then identify the professional service tailored to your needs.
