Millions of people have been given more time to declare their taxes online due to a bug on the French tax website making it impossible to enter income from business and professionals.

The deadlines for declaring 2023 income via the French tax website are staggered in groups according to department number. 

The first to hit deadline were departments 01 (Ain) to 19 (Corrèze) on May 23 at midnight. This was also the deadline for non-residents with French income to declare.

However, already on May 21, many people scrambling to file online found that they could not enter professional and business income (BNC and BIC) - including self-employed income for micro-entrepreneurs (formerly auto-entrepreneurs).

When they tried to do so, they were met with a message stating:

La déclaration en ligne est actuellement indisponible, tout est mis en œuvre pour corriger rapidement ce dysfonctionnement - “Online declaration is currently unavailable, all means are being deployed to correct this error as soon as possible”

The bug was corrected on May 24 - after the deadline had passed for these departments and for non-residents.

The tax website now displays the message:

“Users in departments 1 to 19 as well as non-residents who had difficulties declaring their non-commercial revenue (BNC) and industrial and commercial revenue (BIC) will be given until May 30 to complete their tax declaration.”

The Connexion has contacted the French tax authorities, who were not immediately available to comment on the nature of the problem.
