Updated on 15 April 2026:

Due the high level of interest in individual sessions with the Service des impôts des particuliers (SIP), all available slots have now been booked.

Please note that slots may open up if appointments are cancelled, so we invite you to check the registration tool regularly.

Alternatively, you can consult the following resources:

• The SIP offers telephone appointments, similar to those organised by CERN. You can contact the SIP to request an appointment. You can find more information (opening hours, details) in the admin e-guide.
• The CERN admin e-guide offers several articles about tax issues. See for example the Income tax declaration in France page and an FAQ available prepared by the Valserhône Service des impôts des particuliers.

Original announcement:

In order to help members of the personnel who may need assistance, the Organization has decided to set up individual tax consultation sessions with the French tax authorities (Service des Impôts des Particuliers (SIP) de Valserhône) to answer questions on income tax matters in France. 

These consultations will take place on the Meyrin site, on Friday 17 April 2026 and will be run by ten representatives of the SIP. The sessions will require pre-booking an appointment via this portal.

There are a limited number of time slots available, so we recommend you sign up early.

Please note that these meetings will be in French. Should you need any assistance with the language, we advise you to ask a French-speaking colleague for help.

For any questions regarding these meetings, please contact  SIPTax.support@cern.ch.
