It is available. Since Wednesday, July 30, taxpayers can access the telecorrection service for their 2025 income declaration on the Impots.gouv.fr site. Established by the tax administration, this system makes it possible to rectify any errors or omissions after the end of the declaration period.
Once your tax notice put online in your particular space, between the end of July and early August, period which also corresponds to the reimbursements of the tax administrationit is you possible to modify your tax return. To do this, simply use the “Access to online correction” function on the Impots.gouv.fr site, until December 3, 2025 included. For example, you can modify the number of dependents or members of your tax household. Please note, some information may not be corrected via online service, such as changing family situations or changing your trusted third party.
For people who have made a paper income declaration, you have two options to make your correction: online or by mail addressed to your public finance center specifying your personal and tax information (tax number, tax concerned, etc.).
Correcting your declaration to lower your tax question?
Note that your changes can cause an increase as much as a drop in your tax. If following a stop of the Council of State rendered on May 9, 2025some media and taxpayers have interpreted this decision as a questioning for the taxpayer to the possibility of correcting your declaration to its advantageit is not. This year like the previous ones, you can therefore use this device. The administration is careful to accept or refuse your request.
The public treasury may always reject your request in the event of “serious doubts about the merits of the correction». For example, in case “of manifest inconsistency “ or in “The absence of justification”. As a reminder last year, on 689,473 telecorrections, 424,362 downward corrections were accepted.
