Health insurance for cross-border commuters: KVG or home country

Cross-border commuters and health insurance: which country is responsible

As a cross-border commuter (Grenzgänger / frontalier), you live abroad, work in Switzerland and usually return home every day or at least once a week. For health insurance, the first question is therefore: which country is responsible? The answer comes from the Agreement on the Free Movement of Persons (AFMP) with the EU, whose Annex II makes Regulation (EC) No 883/2004 applicable (Art. 95a of the Federal Health Insurance Act, KVG). The basic principle is the place of work: the country in which you work is responsible.

If you are employed in Basel, Geneva, Lugano or Kreuzlingen and live in the EU, you therefore belong in Swiss basic health insurance (Art. 1 para. 2 let. d of the Health Insurance Ordinance, KVV). There is one exception for the four neighbouring countries Germany, France, Italy and Austria: cross-border commuters who live there may choose their country of residence. This choice is called the right of option, and it only takes effect if you apply.

Country of residence	Health insurance	Legal basis	In depth
Germany	Choice: Switzerland or country of residence	Annex II AFMP, Art. 2 para. 6 KVV	Cross-border commuters from Germany
France	Choice: Switzerland or country of residence	Annex II AFMP, Art. 2 para. 6 KVV	Cross-border commuters from France
Italy	Choice: Switzerland or country of residence	Annex II AFMP, Art. 2 para. 6 KVV	Cross-border commuters from Italy
Austria	Choice: Switzerland or country of residence	Annex II AFMP, Art. 2 para. 6 KVV	Cross-border commuters from Austria
Other EU states, Iceland, Norway, United Kingdom	Switzerland	Art. 1 para. 2 let. d and e KVV	Right of option
Countries outside the EU/EFTA/UK	Switzerland only on your own application	Art. 3 KVV	Right of option

The following sections answer the six questions cross-border commuters ask most often. Each section gives the answer in its first paragraph and points to the article that covers the topic in depth with steps, examples and special cases.

Do I have to take out insurance in Switzerland as a cross-border commuter?

Yes, if you live in an EU or EFTA state or the United Kingdom and work in Switzerland, unless you live in Germany, France, Italy or Austria and choose your country of residence by application. The requirement to take out insurance starts on your first working day in Switzerland and ends when your employment ends.

As a rule, family members who do not work and live with you in the same country are also insured. If they work in your country of residence themselves, they are insured there. Cross-border commuters from countries outside the EU, EFTA and the United Kingdom are not automatically subject to compulsory insurance: they are only covered by Swiss insurance if they apply for it themselves (Art. 3 KVV).

You have 3 months to join a Swiss insurer (Art. 7 para. 8 KVV). If you join on time, cover starts retroactively from the day you started work. If you join later, it only applies from the day you join; you pay treatment costs from before that yourself, and if the delay is inexcusable, you owe a premium surcharge (Art. 5 para. 2 KVG). If you do not take out insurance at all, the canton assigns you to an insurer (Art. 6a para. 3 KVG).

Not every Swiss insurer covers people resident in the EU. According to the FOPH, about a third of health insurers offer this insurance; in the 2026 premium data, there are 13 insurers each for Germany, France and Austria, and 14 for Italy. Which insurers they are and how their key figures differ is shown in the overview:

How does the right of option work, and by when do you have to choose?

Within 3 months of starting your employment, you submit an application for exemption from Swiss compulsory insurance to the responsible office of the canton where you work. You must prove that you are covered for illness in your country of residence, during a stay in another EU state and in Switzerland (Art. 2 para. 6 KVV). Doing nothing is not a choice: without an application, you remain subject to compulsory insurance in Switzerland.

Three rules make the right of option a decision you should prepare carefully:

1. The deadline is short. The 3 months run from your first working day, both for joining a Swiss insurer and for the application for exemption.
2. The choice must be explicit. On 10.03.2015, the Federal Supreme Court ruled (9C_801/2014) that exercising the right of option tacitly is not valid.
3. The choice is irrevocable. According to the Common Institution under the Federal Health Insurance Act (Gemeinsame Einrichtung KVG), it applies for as long as your work as a cross-border commuter continues without interruption. Higher premiums, a new employer or a different canton of work do not reopen it. Only after a documented interruption, such as unemployment in your country of residence, do you get a new right to choose when you take up a new job.

Which documents the application needs, what the process looks like in the individual cantons and what applies on marriage or the birth of a child is explained step by step in the article Cross-border commuters: KVG or home country? The right of option explained, with an example on the deadline.

What does Swiss basic health insurance cost for cross-border commuters?

You do not pay the premium for your place of work, but the premium your insurer has set for your country of residence. The FOPH approves these premiums separately. In 2026, the median for adults aged 26 and over with a CHF 300 deductible and accident cover ranged from CHF 460.35 (Italy) to CHF 526.90 (Germany) per month.

Country of residence	Number of insurers	Lowest premium	Median	Highest premium
Germany	13	CHF 245.00	CHF 526.90	CHF 1,112.90
France	13	CHF 215.00	CHF 515.00	CHF 885.00
Italy	14	CHF 300.00	CHF 460.35	CHF 513.30
Austria	13	CHF 321.90	CHF 481.00	CHF 790.00

The range is wide: for residence in Germany, the difference between the lowest and the highest premium is CHF 867.90 per month, for the same statutory benefits. So comparing is worthwhile, even if only a few insurers are available. The FOPH publishes next year’s premiums at the end of September.

Three rules distinguish insurance for cross-border commuters from insurance for people resident in Switzerland:

• No optional deductible, no cost-saving models. Higher deductibles, bonus insurance and GP, HMO and telemedicine models are not available to insured persons resident in the EU, Iceland, Norway or the United Kingdom (Art. 101a KVV). The standard deductible of CHF 300 applies, plus a 10 % retention fee up to CHF 700 a year (Art. 103 KVV).
• Premium in francs or euros. The insurer charges the premium in Swiss francs or in euros and may ask for it quarterly (Art. 92a KVV).
• Premium subsidy from the canton. Cross-border commuters and their family members on modest incomes receive a premium subsidy from the canton (Art. 65a KVG). How the premium subsidy works in principle is explained under Premium subsidy; the FOPH links to the responsible cantonal offices for insured persons abroad.

The premium calculator uses Swiss premium regions and therefore only fits if you live in Switzerland. You can find the premiums for residence abroad on Priminfo under “EU/EFTA/UK” or directly from the insurer. A sample calculation with median and lowest premium for a cross-border commuter from Germany is in the article on the right of option.

Germany, France, Italy, Austria: what differs by country

The right of option applies to all four neighbouring countries, but the details differ. What contributions you pay in your country of residence and how the system there pays for benefits is governed by the law of that country; the information from the offices there is binding.

Germany

If the cross-border commuter chooses Switzerland, their family members can still take out insurance in Germany: they have a separate right of option, which they may only exercise together. On marriage or birth, anyone insured under the KVG can apply for an exemption within 3 months. The comparison with statutory and private insurance in Germany is covered in the article Cross-border commuters from Germany.

France

If you live in France, you fill in the “Choice of health insurance system” form (Choix du système d’assurance-maladie), have it stamped by the French health insurance fund CPAM and send it within 3 months to the office of the canton where you work. For France, a change in family circumstances does not create a new right of option. The choice only concerns treatment costs; accidents, invalidity and daily allowances are governed by Swiss law. More on this in the article Cross-border commuters from France: LAMal or the French system.

Italy

Italy requires “old” cross-border commuters who have exercised the right of option in favour of Italy to pay a contribution to the national health service: 3 to 6 % of their Swiss net salary, at least 30 and at most 200 euros per month worked (Legge 213/2023, Art. 1 commi 237–239). According to its wording, anyone insured in Switzerland under the KVG is not included. According to media reports from April 2026, Lombardy has announced a rate of 3 % from September 2026; as of 25.09.2026, we could not confirm an official decision by the region. The article Cross-border commuters from Italy: the new health tax follows the situation in the regions.

Austria

Cross-border commuters resident in Austria also have the right of option, and on marriage or birth the 3-month deadline for an exemption applies, as it does for Germany and Italy. For the exemption, you must have equivalent insurance in Austria: according to the Austrian Health Insurance Fund (ÖGK), self-insurance with the ÖGK counts as equivalent, private insurance only after review. What compulsory insurance in Austria means for you is explained in the article Cross-border commuters from Austria.

How do you insure your partner and children as a cross-border commuter?

As a rule, family members who do not work and live in the same country follow your decision: if you are insured in Switzerland, so are they; if you are exempted, the exemption includes them. If your partner works in your country of residence, they and the children must be insured there; Swiss insurance for the children is then not possible.

For children in Swiss basic health insurance, the children’s premium the insurer has set for the country of residence applies. The special rules for Germany (separate right of option for the family) and France (no new choice on marriage or birth) are set out above.

How to insure your family correctly in each situation, for example when a child is born or your partner changes job, is covered in the article Families of cross-border commuters: insuring partners and children correctly. What children cost in Switzerland is shown by the children’s premium calculator for families resident in Switzerland.

Treatment and accidents: what Swiss insurance pays for cross-border commuters

If you are insured under the KVG, you can get treatment in Switzerland and in your country of residence. In Switzerland, the rules of basic health insurance apply; for inpatient treatment, you can choose among the hospitals on the Hospital List. For treatment in your country of residence, your insurer issues form S1; there, the rules and co-payments of your country of residence apply. Outside these rules, basic health insurance pays cross-border commuters abroad no more than twice the amount that would be reimbursed in Switzerland (Art. 36 para. 4 KVV). More on this in the article Treatment abroad.

For accidents, you are usually insured through your employer. If you work at least 8 hours a week for a Swiss employer, compulsory accident insurance under the Accident Insurance Act (UVG) also covers accidents in your free time (Art. 13 para. 1 UVV). You can then suspend the accident cover of your basic health insurance (Art. 8 KVG) and save on the premium; for residence in Germany, the lowest premium in 2026 was CHF 227.90 without accident cover instead of CHF 245.00 with accident cover (FOPH). Whether this is worthwhile for you is calculated by the suspension calculator under Suspend accident cover.

Common mistakes

• Missing the deadline. After 3 months, the right to choose is gone; the canton can assign you to an insurer.
• Treating inaction as a choice. If you stay insured in your country of residence without applying, you have not made a valid choice and remain subject to compulsory insurance in Switzerland.
• Calculating with Swiss regional premiums and cost-saving models. Cross-border commuters pay the premium for their country of residence, without an optional deductible and without a GP or telemedicine discount.
• Hoping to switch later. Higher premiums or a new employer do not reopen the right to choose.
• Forgetting the family. The decision usually also applies to family members who do not work; clarify their situation before you apply.

Where to start?

1. Note your first working day. The 3 months start on that day. Write down the date by which your application or enrolment must be completed.
2. Compare premiums. Get the premiums of Swiss insurers for your country of residence from Priminfo or from the insurers; the insurers’ key figures are in the overview of health insurers, for example in the profile of CSS or Helsana.
3. Check your country of residence. Ask the health insurance in your country of residence which contributions and benefits apply to you and your family there.
4. Decide and act. Country of residence: apply to the canton where you work, with the form stamped by the CPAM if you live in France. Switzerland: join an insurer that accepts insured persons from your country of residence.
5. Clarify accidents and subsidies. If your employer provides UVG cover, check suspending accident cover; if your income is low, apply for a premium subsidy.
