Health Insurance Switzerland: the first 3 months after moving

You are moving to Switzerland or working as a cross-border commuter? Then health insurance is one of the first and most important matters you need to clarify. In Switzerland, there is a mandatory health insurance requirement, and the first three months after moving are crucial for your registration, your rights and potential fines.

In this article, you will learn everything you need to know about health insurance in the first three months after moving to Switzerland: deadlines, registration process, costs, exceptions and typical mistakes.

1. Insurance obligation from day one

In Switzerland, mandatory health insurance (OKP) applies to all persons with a place of residence or employment in Switzerland. The insurance obligation begins from the first day of residence or when you start working, regardless of your nationality or residence status.

This means: even if you register with a health insurance provider later, you are legally insured from day one and must pay the premiums retroactively.

The legal basis is the Federal Health Insurance Act (KVG). Further information can be found at the Federal Office of Public Health (BAG) at bag.admin.ch.

2. The 3-month registration deadline

You have three months from your move to Switzerland to register with a health insurance provider. This deadline is set by law and monitored by the canton. If you do not register within this deadline, the canton can assign you to a health insurance provider and impose an additional fine.

What happens during the 3 months?

• You are still covered: Even without formal registration, you are subject to the insurance obligation from day one.
• Retroactive cover: Once you register, the insurance is retroactively valid from day one.
• Premium obligation: You must pay all premiums from day one, even if you register later.

What happens after the 3-month period expires?

If you do not register in time, the following will happen:

• The canton will assign you to a health insurance provider.
• You will receive a fine (depending on the canton between CHF 100 and CHF 500).
• You will have to pay all premiums retroactively from day one.

3. Registration with a health insurance provider: How to proceed

Registration with a health insurance provider is straightforward, but requires some important steps. Here is the typical process:

Step 1: Register your place of residence (civil register office)

Before you register with a health insurance provider, you must register at the civil register office (municipality). This must be done within 14 days of your move. You will receive a residence confirmation, which you will need for your health insurance registration.

Step 2: Choose a health insurance provider

In Switzerland, there are over 40 approved health insurance providers. You can choose freely. Important criteria:

• Premium: Basic benefits are identical at all insurers (according to KVG). However, premiums vary significantly.
• Deductible: The higher the deductible (CHF 300 to CHF 2,500), the lower the monthly premium.
• Insurance model: Standard, family doctor model, HMO, telehealth.
• Supplementary insurance: Optional, but not mandatory.

Step 3: Complete the registration form

Once you have chosen a health insurance provider, fill out the registration form. You will need:

• Residence confirmation
• Residence permit (if applicable)
• AHV number (if available, otherwise to be provided later)
• Details of previous insurance (EU/EHV, if applicable)

Step 4: Receive confirmation

You will receive a policy and your insurance card within a few days. The insurance is retroactively valid from the first day of your residence.

4. Costs and premium levels

The premiums of mandatory health insurance vary widely depending on age, location and insurance model. Here are some typical values (as of 2026):

Premium assistance (premium subsidies)

If your income is below a certain threshold, you can apply for premium assistance (individual premium subsidy). This is covered by the canton. For more information, visit your canton's website or go to ahv-iv.ch.

5. Retroactive cover and back payments

One of the key rules in Switzerland: You are covered from day 1 of your residence, even if you register later. This means:

• If you need treatment before you register, it will still be covered.
• You must pay all premiums retroactively from day 1.
• You cannot choose to "start" your insurance later.

Back payment of premiums

Most health insurance providers allow you to pay back premiums in monthly instalments rather than as a lump sum. Clarify this when you register.

6. Exceptions: Cross-border commuters and EU/EFTA citizens

Cross-border commuters (Grenzgänger)

If you work in Switzerland but live abroad (particularly in neighbouring countries like Germany, France, or Italy), you may be able to keep your previous insurance. However, this applies only if:

• You are employed in Switzerland.
• You live in a neighbouring country and commute daily or weekly to Switzerland.
• You have a valid cross-border commuter permit (G permit).

In this case, you can remain insured in your home country's system. However, you still need to register and notify Swiss authorities of your cross-border status. Check with your cantonal health authority for exact requirements.

EU/EFTA citizens newly arriving in Switzerland

EU and EFTA citizens are subject to the same mandatory insurance requirement as Swiss citizens. They must register within 3 months. However, they can use their European Health Insurance Card (EHIC) until the Swiss insurance takes effect.

7. Common mistakes and how to avoid them

Mistake 1: Thinking you can wait to register

Reality: The insurance obligation begins on day 1. Waiting until month 3 to register will cost you retroactive premiums for all 3 months.

Solution: Register within the first 1-2 weeks of your arrival.

Mistake 2: Choosing the cheapest insurance without comparing deductibles

Reality: A low monthly premium combined with a high deductible (CHF 2,500) may be more expensive overall if you use healthcare frequently.

Solution: Use comparison portals and calculate your total costs including potential deductibles.

Mistake 3: Not registering at the civil register office first

Reality: Most health insurance providers require a residence confirmation from the municipality. Without it, you cannot register.

Solution: Register at the civil register office within 14 days of arrival. This only takes a few minutes.

Mistake 4: Forgetting about supplementary insurance

Reality: Mandatory insurance covers only basic medical care. Dental and optical care, for example, are usually not covered.

Solution: Consider supplementary insurance (Zusatzversicherung) if you need dental or optical coverage. Register for this at the same time as mandatory insurance, as some insurers have waiting periods.

Mistake 5: Not updating your insurance after a move within Switzerland

Reality: If you move to a different canton, you may be able to change insurers. Some insurers do not operate in all cantons.

Solution: Check whether your current insurer operates in your new canton. If not, you have the right to terminate the contract without notice when you move.

8. Conclusion

Health insurance is one of the most important matters to sort out when moving to Switzerland. The key points:

• Register within 3 months to avoid fines and bureaucratic complications.
• The obligation begins on day 1, so register as early as possible.
• Compare prices carefully using online comparison portals.
• Understand your deductible - it affects both monthly premiums and your total out-of-pocket costs.
• Register at the civil register office first - you will need a residence confirmation.
• Check canton-specific rules - the cantonal health authorities can provide additional guidance.

By following these steps and avoiding common mistakes, you will have proper health insurance coverage from day one and avoid unnecessary stress and costs during your first three months in Switzerland.
