Any person performing a salaried activity for more than 8 hours a week in Switzerland is covered by an accident insurance (LAA) scheme, which covers damage sustained in the event of an illness or accident of an occupational or private nature.

You must declare the income or pension in the original currency. You can declare several amounts in different currencies by adding an income source (e.g. an income and a subsistence allowance). The official exchange rate in force at CERN on the effective date of your declaration will be used to produce the conversion into Swiss francs, and this is displayed immediately in the EDH form.
Do not convert the amount into Swiss francs yourself.

For spouses who are associated members of the personnel, it is therefore necessary to declare the income received from the home institute, as well as any subsistence allowance paid during the period of association with CERN. The various incomes must be declared in a single document.

Membership of the CERN health insurance scheme (CHIS) is compulsory* for technical, doctoral or administrative student. CHIS provides for reimbursement of a major portion of reasonable and customary expenses resulting from medical treatment within the conditions specified in its Rules, incurred by its Members.
