As the CHIS contribution rates are unchanged for 2020, the CHIS contributions will only evolve if there is a change in the relevant Reference Salary (see Chapter XII of the CHIS Rules). For instance, as of 1 January 2020, the lump-sum monthly contributions based on Reference Salary II will be as follows:

1. Lump-sum contributions for voluntary members
The monthly contribution for voluntary members (e.g. users and associates) with the normal health insurance will be 1229 CHF per month, whilst for those with the reduced health insurance it will be 615 CHF.

2. Lump-sum contributions for post-compulsory members other than CERN pensioners
For post-compulsory members other than CERN pensioners, the monthly contribution will be 1313 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 525 CHF.
