Individuals domiciled in Luxembourg are subject to income tax on their worldwide income unless exempt under the provisions of a treaty. Under Luxembourg tax law, the concept of ‘domicile’ is essentially equivalent to the term ‘residence’ as used in most jurisdictions. In this article, the two terms are used interchangeably. Non-residents are subject to income tax on certain categories of income from Luxembourg sources. The official currency of Luxembourg is the euro (EUR).
