Memorandum concerning the 2011 internal taxation certificate and the 2011 income tax declaration forms issued by the Swiss cantonal tax administrations.

You are reminded that the Organization levies an internal tax on the financial and family benefits it pays to the members of the personnel (see Chapter V, Section 2 of the Staff Rules and Regulations) and that the members of the personnel are exempt from federal, cantonal and communal taxation on salaries and emoluments paid by CERN.

I - Annual internal taxation certificate for 2011

The annual certificate of internal taxation for 2011, issued by the Finance, Procurement and Knowledge Transfer Department, is available as of 1 March 2012. It is intended exclusively for the tax authorities.

1. If you are currently a member of the CERN personnel you will receive an e-mail containing a link to your annual certificate, which you can print out if necessary.
