As the CHIS contribution rates are unchanged for 2021, the CHIS contributions have evolved with the change in the relevant Reference Salary (see Chapter XII of the CHIS Rules). Thus, as of 1 January 2021, the lump-sum monthly contributions based on Reference Salary II will be as follows:

• Lump-sum contributions for voluntary members

The monthly contribution for voluntary members (e.g. users and associates) with the normal health insurance will be 1235 CHF per month, whilst for those with the reduced health insurance it will be 617 CHF.

• Lump-sum contributions for post-compulsory members other than CERN pensioners

For post-compulsory members other than CERN pensioners, the monthly contribution will be 1319 CHF in the case of former staff members and former spouses continuing their affiliation, whilst in the case of formerly dependent children continuing theirs it will be 528 CHF.
