Luxembourg Inland Revenue

Management

The management of the inland revenue is in contact with taxpayers when dealing with legal action in case of a claim regarding tax returns. Furthermore, it makes decisions regarding applications for reconsideration.

Taxation department 

The taxation department establishes tax rates for taxpayers. The department is divided into different sections. In addition to the corporate and withholding tax on interest section, the taxation department has the following:

Natural persons section 

This section consists of 28 offices located throughout the country. Each one is responsible for a different part of the country. Three tax offices have jurisdiction over non-resident taxpayers residing abroad:

  • the Tax Office Luxembourg X has jurisdiction over non-resident taxpayers whose tax residence is in Belgium or in another country (apart from employees whose tax residence is in Germany or France);
  • the Tax Office Luxembourg Y has jurisdiction over non-resident taxpayers whose tax residence is in France;
  • the Tax Office Luxembourg Z has jurisdiction over non-resident taxpayers whose tax residence is in Germany;

The offices centralise income tax returns for resident and non-resident taxpayers. An officer is responsible for issuing tax returns and determining the advances to be paid, where applicable.

Section for withholding tax on wages and salaries (retenue d'impôt sur les traitements et salaires – RTS)
