The electronic leap: the tax revolution in Luxembourg

The digitalisation of tax administration in Luxembourg has reached a new milestone. In 2025, within just three weeks of the opening of the possibility to file a tax return via an electronic assistant on the MyGuichet.lu portal, residents sent more than 10,000 declarations. This is three times faster than in 2024, when this figure was reached only three months later - and PDF filing was still dominant then.

This time it's different: the electronic assistant is gradually becoming a standard. This surge of interest in the digital tool is due not only to technical progress, but also to the real advantages it offers.

The electronic assistant is not just a form, but a real navigator through the bureaucratic jungle. Already at the first login, the user sees automatically filled in fields: name, address, information about children, salary or pension (if applicable) - all this data is downloaded from the servers of government agencies and employers. This shortens the submission time, reduces the risk of errors and makes the process predictable.

Moreover, if a citizen's tax situation is straightforward, they can receive their final tax calculation in as little as two weeks - a result that is similar to express delivery, only in the world of public service.

To facilitate adaptation, the public services have developed video guides in French, German and English. They are available on the websites 123easy.lu, Guichet.lu and on the YouTube channel of the Administration des contributions directes (ACD).

In parallel, feedback is also being collected: together with the Centre des technologies de l'information de l'État (CTIE), an online survey has been created to assess the user experience. Its aim is not just to improve the interface, but to make the tax return process as clear and stress-free as possible.

The questionnaire can be found on the same platforms - 123easy.lu and the www.zesumme-vereinfachen.lu website initiated by the Ministry of Digitalisation. The name of the website, by the way, translates from Luxembourgish as "simplifying together" - and it seems that in 2025, this mission has started to take on real features.
