Key points at a glance
- The KVAG has been in force since 01.01.2016 and only applies to basic health insurance, not to supplementary insurance.
- The supervisory authority is the Federal Office of Public Health (Art. 56 KVAG).
- Every insurer needs an authorisation, must hold reserves and must have its premiums approved by the FOPH before publishing them.
- In the solvency test as at 01.01.2025, the reserves of all insurers together stood at 147% of the minimum reserves.
What is the KVAG?
The KVAG is the federal act under which the Confederation supervises health insurers in basic health insurance. Parliament passed it on 26 September 2014, and it has been in force since 1 January 2016. Before that, the supervisory rules were scattered across the Federal Health Insurance Act (KVG) and the Health Insurance Ordinance (KVV).
The act has a clear purpose: it is meant to protect the interests of insured persons, above all through transparency in social health insurance and through the solvency of health insurers (Art. 1 para. 2 KVAG). Solvency means that the insurer can meet its obligations at all times, even in a year with unexpectedly high costs.
The KVAG applies to everyone who provides basic health insurance: the health insurers (legal entities that do not pursue a profit motive), private insurance companies with an authorisation, reinsurers and the Common Institution under the Federal Health Insurance Act. It does not apply to supplementary insurance. That is governed by the Insurance Contract Act (ICA) and supervised by FINMA.
Alongside the act, there is the implementing ordinance, the Health Insurance Supervision Ordinance (KVAV). It sets out how reserves are calculated, when premiums must be submitted and how repayments work.
How it works: supervision under the KVAG
Authorisation: Only insurers authorised by the FOPH may offer basic health insurance (Art. 4 KVAG). The requirements include a legal form as a company limited by shares, a cooperative, an association or a foundation, a registered office in Switzerland, sufficient reserves, an audit firm and the obligation to accept every person in its area of activity who is required to take out insurance (Art. 5 KVAG). The FOPH publishes the list of authorised insurers.
Reserves: Every insurer must build up sufficient reserves to remain solvent (Art. 14 KVAG). The minimum amount is calculated by the solvency test. It is set so that, even in the worst 1% of possible developments over a year, the reserves do not fall below zero on average (Art. 11 KVAV). If the reserves exceed the minimum, the insurer may reduce them voluntarily, for example through tightly calculated premiums or an adjustment on the premium invoice (Art. 26 KVAV).
Approval of premiums: Premiums for basic health insurance require approval by the FOPH and may neither be published nor applied before then (Art. 16 para. 1 KVAG). The insurer submits them at the latest five months before they take effect (Art. 27 KVAV). The FOPH refuses approval if the premiums do not cover the costs, are inappropriately high compared with the costs or lead to excessive reserves (Art. 16 para. 4 KVAG). The cantons can comment beforehand.
Repayment: If premium income in a canton was significantly higher than the costs, the insurer can make an adjustment in the following year (Art. 17 KVAG). The money goes to everyone who was insured with it on 31 December of the year concerned (Art. 18 KVAG).
Administration and intermediaries: Administrative costs must be limited to what is necessary; the insurer shows advertising and intermediary commissions separately (Art. 19 KVAG). Since 01.09.2024, Art. 19a and 19b KVAG have governed the activities of intermediaries: insurers can agree, among other things, on a ban on telephone advertising to people who have never been insured with them or have not been for some time, a cap on commissions and signed advice records, and the Federal Council can declare these rules binding on all insurers.
Legal basis
The KVAG has the number SR 832.12 and is based on Art. 117 para. 1 of the Federal Constitution. The most important articles for insured persons:
| Article | Content |
|---|---|
| Art. 1 KVAG | Subject matter and purpose: protecting insured persons, transparency, solvency |
| Art. 2 KVAG | Health insurers do not pursue a profit motive; supplementary insurance is governed by the ICA |
| Art. 4–5 KVAG | Authorisation and requirements for authorisation |
| Art. 14 KVAG | Obligation to hold sufficient reserves |
| Art. 16 KVAG | Approval of premium tariffs by the supervisory authority |
| Art. 17–18 KVAG | Adjustment and repayment of excessive premium income |
| Art. 19–19b KVAG | Administrative costs and rules for insurance intermediaries |
| Art. 34 KVAG | Tasks of the supervisory authority, including protection against abuse |
| Art. 56 KVAG | The FOPH carries out supervision |
Breaches are punishable: anyone who operates social health insurance without authorisation risks a custodial sentence of up to three years or a monetary penalty (Art. 53 KVAG). For certain breaches of duty, Art. 54 KVAG provides for fines of up to CHF 500,000.
Example: from the premium application to cancellation
The process for one year’s premiums shows how the KVAG and the KVG work together. Here for the 2027 premiums, with the statutory deadlines:
| Step | Deadline | Basis |
|---|---|---|
| Insurer submits its premium tariff to the FOPH | by 31 July 2026 at the latest (five months before 1 January) | Art. 27 para. 1 KVAV |
| Cantons comment, FOPH reviews and approves | before publication | Art. 16 KVAG |
| Insurer notifies you of the new premium | by 31 October 2026 at the latest (two months before) | Art. 7 para. 2 KVG |
| You cancel your basic health insurance | by 30 November 2026 (one month’s notice) | Art. 7 para. 2 KVG |
| New premium applies | 1 January 2027 | Art. 27 para. 4 KVAV |
A ratio below 100% does not mean that an insurer is insolvent. It must, however, rebuild its reserves, and the FOPH takes this into account when approving premiums.
What this means for you
The KVAG works in the background, but you benefit from it directly:
- You can choose any insurer. Every authorised insurer must accept you for basic health insurance. The overview of health insurers shows which insurers exist and what their key figures look like.
- New premiums are checked. No insurer may charge a premium that the FOPH has not approved. Compare the approved premiums in the premium calculator as soon as they are published.
- You have a right to switch. Once you are notified of the new premium, you can cancel by 30 November. The steps are under switch insurer and deadlines.
- Intermediaries have rules. Since 01.09.2024, the Federal Council can declare insurers’ rules on telephone advertising, commissions and advice records binding on all insurers (Art. 19b KVAG). Do not sign anything you have not understood.
Common mistakes
- Confusing the KVAG and the KVG. The KVG governs your rights and benefits, the KVAG the supervision of insurers.
- Believing the FOPH sets the premiums. Each insurer calculates its own premiums. The FOPH only reviews and approves them.
- Assigning supplementary insurance to the KVAG. Supplementary hospital and outpatient insurance is governed by the ICA and the ISA and supervised by FINMA.
- Thinking high reserves are bad. Reserves secure an insurer’s ability to pay. The FOPH can, however, object to excessive reserves when approving premiums.

Frequently asked questions
What does KVAG stand for?
KVAG is the German abbreviation for the Health Insurance Supervision Act. Its full title is the “Federal Act on the Supervision of Social Health Insurance”. Its number is SR 832.12.
What is the difference between the KVG and the KVAG?
The KVG governs who is insured, which benefits are paid and how the co-payment works. The KVAG governs how the Confederation supervises health insurers, meaning authorisation, reserves, approval of premiums and administration.
Does the KVAG also apply to supplementary insurance?
No. Supplementary insurance is governed by the Insurance Contract Act (ICA) and supervised by FINMA under the Insurance Supervision Act (ISA). The FOPH and FINMA coordinate their supervision (Art. 34 para. 5 KVAG).
Can an insurer pay back premiums that were too high?
Yes. If premium income in a canton was significantly higher than costs, the insurer can apply for an adjustment in the following year (Art. 17 KVAG). The repayment goes to everyone who was insured with it on 31 December of the year concerned.
Related terms
- Federal Office of Public Health (FOPH)The FOPH (BAG in German) is the Federal Office of Public Health in Bern, part of the Federal Department of Home Affairs. In health insurance, it supervises the health insurers, approves basic health insurance premiums every year, keeps the List of Pharmaceutical Specialties of reimbursed medicines and publishes the official premium data, for example on priminfo.admin.ch.
- Health insurers’ reservesReserves are a health insurer’s equity capital in basic health insurance: the amount by which its assets exceed its liabilities. They ensure that the insurer can still pay in an expensive year. As at 01.01.2025, all insurers together held CHF 7,772.0 million in reserves, 147% of the statutory minimum.
- Premium approvalPremium approval is the annual review of basic health insurance premiums by the Federal Office of Public Health (FOPH). Health insurers submit their tariffs no later than five months before 1 January. Only after approval may they publish and apply the premiums; for 2026, the average premium rose by 4.4 %.
- Health insurerA health insurer is a company licensed by the Federal Office of Public Health (FOPH) to provide basic health insurance under the KVG; in everyday language, a health insurance fund. As at 01.01.2026 there were 34 of them. They must accept every person required to take out insurance, may not make a profit from basic health insurance and often also offer supplementary insurance under the ICA.
- KVAV (Health Insurance Supervision Ordinance)The KVAV is the Federal Council’s Health Insurance Supervision Ordinance. Since 01.01.2016, it has set out the details of the KVAG: the minimum reserves health insurers must hold, how premiums are approved, when excess premiums are paid back and which rules apply to intermediaries. It only concerns basic health insurance.
- Solvency testThe KVG solvency test checks every year whether a health insurer has enough reserves to survive even a very bad year. The result is the solvency ratio: available reserves divided by the required minimum level. Below 100%, the insurer must take action. As of 01.01.2025, the ratio for the industry as a whole was 147%.
