The Luxembourg Inland Revenue (ACD) has outlined in a press release the key dates and new measures for the 2025 tax return season, including the expanded use of pre-filled declarations and additional support for taxpayers.
According to the press release, a key development this year is the expansion of the simplified pre-filled tax return. From 30 March, eligible taxpayers will receive a pre-completed declaration by post, based on data already held by the tax authorities.
This marks the next phase of a system first introduced in March 2025, designed to streamline the process and enable taxpayers to receive their tax assessment within a predictable timeframe of around two weeks, according the press release.
Taxpayers will still have the standard deadline to complete the process, with pre-filled returns to be signed and returned by 31 December 2026.
Importantly, the ACD states in the press release that the official filing period for all types of tax returns opens on 7 April. Individuals and organisations will then have until 31 December 2026 to submit their declarations.
As part of its efforts to improve accessibility and engagement, the ACD will once again organise its ‘123easy! Tax Week’ from 18 to 23 May, according to the press release.
Following the success of last year’s edition, the initiative will see ACD representatives visit five shopping centres across the country as part of the ‘ACD on Tour’ campaign, aimed at answering taxpayers’ questions directly.
The campaign seeks to bring tax information closer to the public, helping to clarify procedures, raise awareness of the pre-filled tax return, and introduce the MyGuichet.lu online assistant.
Alongside the information campaign, the ACD’s human resources team will also be present to showcase career opportunities within the administration.
For further information, taxpayers can contact the ACD Contact Centre by phone on (+352) 247-53000 or via the contact form available on acd.lu.
