Memorandum concerning the 2020 internal tax annual certificate, the individual annual statement and the 2020 income tax declaration forms issued by the Swiss cantonal tax authorities


I – Internal tax annual certificate and individual annual statement for 2020

The internal tax annual certificate or the individual annual statement for 2020, issued by the Finance and Administrative processes Department, is available since 12 February 2021 via HRT (under « My e-Documents and Self Services »). The document that you have received (certificate or statement) depends on your situation at CERN in 2020. It is intended exclusively for the tax authorities.

  1. If you are currently a member of the CERN personnel you have received an e-mail containing a link to your certificate or statement, which you can print out if necessary.
  2. If you are no longer a member of the CERN personnel or are unable to access your certificate or statement as indicated above, you will find information explaining how to obtain one here.

In case of difficulty in obtaining your certificate or statement, send an e-mail explaining the problem to service-desk@cern.ch.

II - 2020 income tax declaration forms issued by the Swiss cantonal tax authorities

The Admin e-guide and an FAQ can be found on this page to provide further general indications for completing the 2020 income tax declaration form, and to offer support in this matter.


This information does not concern CERN pensioners, as they are no longer members of the CERN personnel and are therefore subject to the standard national legal provisions relating to taxation.

NB: The information regarding the French income tax declaration form is usually available in April.
