It is however possible, as every year, to rectify after the deadline its tax return for the previous year: the service concerned, accessible online, opens in effect this Wednesday. It will be available until December 7.

In addition, the process can be done as many times as necessary. It is also possible to modify the declarations of the two previous tax years, although the administration encourages them to be corrected as soon as possible.

Please note, however, that this process is only valid for a declaration made online: in the case of a paper declaration, the service is not available. You will then have to request a correction directly from the relevant tax department. Finally, for corrections made online, it is not possible to attach supporting documents, especially in the case of a change in family situation such as a PACS or death. However, it is recommended to keep them available to the tax services if necessary.
