The three-month rule
Anyone settling in Switzerland must normally obtain compulsory basic health insurance within three months of taking up residence. Each family member is insured separately.
For the surrounding context, see Swiss residence routes.
Do not interpret that as three free uninsured months. If you enrol on time, the obligation and premiums generally run from the start of residence.
What basic insurance costs in 2026
The Federal Office of Public Health reports an average 2026 premium across all insured persons of CHF 393.30 per month, up 4.4% from 2025.
Average 2026 monthly premiums are:
| Group |
Average monthly premium 2026 |
| Adults 26+ |
CHF 465.30 |
| Young adults 19-25 |
CHF 326.30 |
| Children |
CHF 122.50 |
Your actual price depends on canton, premium region, insurer, model and deductible.
The deductible and co-payment
For adults, the standard annual deductible is CHF 300. Children under 18 have no standard deductible.
For the surrounding context, see EU/EFTA residence.
After the deductible, the standard retention fee is 10% of covered costs, capped at CHF 700 per year for adults and CHF 350 for children. Certain medicines can attract a higher cost share where the statutory rules apply.
With the ordinary CHF 300 adult deductible, that means a standard maximum of CHF 1,000 in deductible plus retention fee, before premiums and any separate hospital contribution or special rules.
A higher deductible is a calculated bet
Adults can select an optional deductible up to CHF 2,500. A higher deductible reduces premiums but increases the amount you carry yourself if you need care.
Do not choose CHF 2,500 because a comparison site highlights the lowest premium. Model the annual premium saving against your expected medical spend and the additional risk you can comfortably absorb.
If this decision changes the viability or sequence of your move, a Swiss relocation strategy consultation can apply it to your own facts.
The model can matter as much as the insurer
Basic-insurance benefits are defined by law. What changes across models is primarily how you access care.
For the surrounding context, see the B permit.
Typical models include:
- standard/free choice of doctor;
- family-doctor model;
- HMO/network model;
- telemedicine-first model.
A cheaper model is not “worse medicine”; it normally involves a more restricted first point of contact.
Basic and supplementary insurance are different worlds
Compulsory basic insurers must accept applicants under the statutory system. Supplementary insurance is private insurance: the insurer can underwrite risk, ask health questions, apply exclusions or refuse an application.
Do not delay compulsory cover because you are negotiating supplementary cover.
Annual switching deadlines
For a normal switch effective 1 January, the cancellation must generally reach the insurer by 30 November. Model changes and moves to a lower deductible also typically use the 30 November deadline; a move to a higher deductible can generally be requested by the end of December for the following year, subject to the statutory framework and insurer process.
Put health insurance next to tax when choosing a canton
A low-tax canton is not automatically a low-cost canton. Premiums can differ materially by canton and premium region.
For a family, compare at least:
income tax + wealth tax + rent + health premiums + childcare + commuting.
That total, not the headline tax rate, is the number that determines whether Switzerland actually improves your life.
