In March 2026, the Direct Tax Adminisrtration (ACD) will complete a new stage in its modernisation project by bringing together several of its services currently located in the Luxembourg train station district on a single site, located at the Cloche d’Or. The new offices will be located at 18–20 rue Eugène Ruppert, in the Laccolith building, at the heart of a district undergoing major administrative and tertiary development.

The aim of this relocation is to improve reception conditions for the public and to rationalise the organisation of services. The geographical grouping of personal tax offices should simplify procedures for taxpayers, while providing more modern and better adapted infrastructures, particularly in terms of accessibility for people with reduced mobility. The administration has indicated that a more detailed communication will accompany the actual move.

The transfer will affect the Luxembourg personal income tax offices 1 to 9, the RTS Offices 2 and 3, the Luxembourg Revenue Office and the Property Valuation Department. The non-resident tax offices, meanwhile, will remain located in the Yris building at 21 rue Eugène Ruppert, in the immediate vicinity of the new site.

A neighbourhood undergoing gradual conversion

The choice of the Laccolith building is part of a singular continuity. The building has already had several institutional and economic lives, having successively housed teams from ArcelorMittal, PwC and the European Commission. Its occupation by the tax authorities marks a new stage in the gradual conversion of the district into a major administrative hub in the south of the capital.

Waiting for the move, the ACD would like to remind everyone that the preferred channel for contacting its services remains the contact form available on its website, where a frequently asked questions section also centralises the most frequent requests from taxpayers. A way of admitting that the site is less central than its current location, even though the tram passes about 300 metres away.
