# Changing health insurance (LAMal vs CMU/GKV/SSN): reopening the right of option in 2026

The right of option is, as a rule, irrevocable. Here are the only status changes (unemployment, moving, retirement) that reopen it across France, Germany and Italy, the strict 3-month deadline and the exact steps to switch between LAMal and your national system.

📌 In short: reopening your LAMal/national right of option

-   **The principle:** the choice between LAMal and your national system (CMU, GKV/PKV or SSN) made on first employment is **final**. You cannot switch for purely financial reasons.
-   **The exceptions:** only three events reopen the right of option — resuming Swiss work **after subsidized unemployment in your country of residence**, moving from Switzerland to a neighbouring country and retiring on an exclusively Swiss pension. You then have **3 strict months** to act, otherwise you are automatically affiliated with LAMal. Switzerland has concluded a separate agreement with each of its neighbouring countries: this list reflects one of them, and residents of Germany, Italy or Austria should check their own with their insurance body.
-   **The ibani solution:** whether you pay national premiums in euros or LAMal in francs, convert your CHF at the real rate, plus a transparent margin of 0.40% to 0.15% depending on the amount, using an [ibani account](https://www.ibani.com/en/app) to protect your purchasing power.

For cross-border workers residing in France, Germany or Italy, choosing between the Swiss health insurance system (LAMal) and their national system (CMU, GKV/PKV or SSN) is governed by the "right of option". As a general rule, this initial choice is strictly irrevocable. However, Swiss legislation and the bilateral agreements recognise specific major life events that qualify as a "change of situation" and grant a new opportunity to choose. This guide details the scenarios that reopen this right in 2026 across all three neighbouring countries, the strict three-month legal deadline, and the administrative steps required.

| Change of situation | Is the right of option reopened? | Legal deadline |
| --- | --- | --- |
| **New Swiss employment contract with no prior interruption** | No. Simply changing employers does not reopen the right. | N/A |
| **Moving from Switzerland to France, Germany or Italy** | Yes. The resident officially becomes a cross-border worker. | 3 months |
| **Resuming Swiss work after subsidized unemployment in the country of residence** | Yes. Registering with the national unemployment agency resets the status. | 3 months |
| **Retirement (receiving exclusively a Swiss pension)** | Yes. A fundamental change in the social security regime. | 3 months |
| **Marriage or birth of a child** | No (only affects the affiliation of dependents). | N/A |

## 1\. Is the right of option really irrevocable?

Yes, in principle. The health insurance choice made during the first three months of cross-border employment in Switzerland is definitive, and you cannot switch from LAMal to a national system (or vice versa) simply to reduce your monthly costs or because premiums rise.

Under the bilateral agreements between Switzerland and its neighbours, every cross-border worker must exercise their "right of option" [within 3 months of their first job in Switzerland](https://www.bag.admin.ch/en/health-insurance-cross-border-commuters-working-in-switzerland). Once made and validated by the authorities, this choice binds you for the entire duration of your cross-border activity. It is a stability rule intended by both states: it prevents insured persons from moving between systems depending on their health or the evolution of premiums.

However, certain major life events essentially reset a worker's administrative status. These "changes of situation" grant a new, strict **3-month (90-day) window** to exercise a new right of option. Outside these exhaustively listed cases, no switch is possible. To understand the underlying difference between the systems before reopening your choice, read our comparison guide on [cross-border worker health insurance: LAMal or your national system](https://www.ibani.com/en/guides/crossborder-worker-insurance).

## 2\. Which situations reopen the right of option (France, Germany, Italy)?

Three changes of situation, and only these three in 2026, reopen the right of option: resuming Swiss work after unemployment in your country of residence, moving from Switzerland to a neighbouring country and retiring on an exclusively Swiss pension. Each one opens a 3-month window.

### A. Resuming employment after a period of unemployment

If a cross-border worker loses their job in Switzerland, they fall under the unemployment system of their country of residence: Pôle Emploi / France Travail in France, the Agentur für Arbeit in Germany, or INPS (NASpI) in Italy. During this period of subsidized unemployment, the individual is compulsorily affiliated with their national social security system. Upon signing a **new employment contract in Switzerland**, this is legally considered a "new start of activity", which reopens the right of option. To anticipate the full unemployment-to-rehire sequence, see our guide on [dismissal and unemployment in Switzerland](https://www.ibani.com/en/guides/getting-fired-in-switzerland).

### B. Moving from Switzerland to a neighbouring country

An expatriate (B permit holder) who is compulsorily affiliated with LAMal and decides to relocate to a neighbouring country — for example moving from Geneva to Annemasse, Zurich to Konstanz, or Lugano to Como — experiences a change in legal status, becoming a cross-border worker (G permit). This relocation grants them the right to choose between keeping a LAMal cross-border policy or joining their national system (CMU, GKV or SSN).

### C. Transitioning to retirement

The liquidation of pension assets modifies a worker's social security allegiance. If the former cross-border worker receives **exclusively a Swiss pension** (and no pension from their country of residence), they are granted a new right of option to determine their healthcare coverage as a retiree. Note that receiving even a single national pension generally closes this possibility, as it ties you to your national system. Our guide to [health insurance in retirement](https://www.ibani.com/en/guides/health-insurance-retirement-cross-border-worker-right-of-option) covers the deadlines, the countries concerned and the cost of each choice.

**Short-term assignment:** when your activity in Switzerland lasts less than 90 days per year, affiliation with LAMal or your home-country system remains optional. The obligation to choose only applies beyond this threshold.

**⚠️ What does NOT reopen the right of option:**
Simply changing employers in Switzerland (with no interruption or unemployment), changing your working hours (part-time to full-time), marriage or the birth of a child do not allow you to change your own insurance choice. Marriage and birth only serve to determine the affiliation of dependents (a spouse without income, children).

## 3\. How do you actually change your health insurance?

As soon as the change of situation takes effect, the 3-month countdown begins (the start date of the new contract or the official moving date). The procedure has three steps, with an exemption form that must be stamped by your chosen insurer and validated by the canton.

**Step 1 — Obtain the cantonal exemption form:**
You must acquire the official form to request an exemption from compulsory Swiss health insurance. This form is specific to your canton of employment (for example SAM in Geneva, OVAM in Vaud, SVA in Zurich).

**Step 2 — Register with the chosen system:**

-   **If choosing the national system (France: CMU, Germany: GKV/PKV, Italy: SSN):** register with your local health authority — CPAM in France, a German Krankenkasse (AOK, TK, Barmer), or an Italian ASL/ATS. This authority must stamp and sign the Swiss form to certify that your coverage meets the equivalent standards.
-   **If choosing the Swiss system (LAMal):** take out a basic cross-border insurance policy with a Swiss provider (e.g. Helsana, Swica). They will issue an S1 form, which you submit to your local health authority so that your medical costs are covered in your country of residence.

**Step 3 — Cantonal validation:** the fully completed and stamped dossier must be submitted to the relevant Swiss cantonal authority within the 3-month deadline for final validation. It is this authority that definitively confirms your exemption or your affiliation.

**⏱️ The deadline trap:**
If you do not submit the validated form within 3 months of your change of situation, the Swiss authorities automatically affiliate you with LAMal — and you remain affiliated with it until the next change of situation that reopens the right of option. Never treat this deadline lightly.

If you stay with LAMal, check how your care is covered in your country of residence through the S1 form, explained in our guide on [what LAMal covers abroad (S1 form)](https://www.ibani.com/en/guides/lamal-health-coverage-france-germany-italy-s1-form).

## 4\. Late affiliation: what penalty applies for missing the deadline?

Missing the 3-month deadline does not only mean losing access to your home-country system (CMU, GKV or SSN) and being automatically affiliated with LAMal: a **premium surcharge** may also apply. The good news is that its impact remains limited, and the months of delay are not billed retroactively.

### The amount of the surcharge

If the cross-border worker does not affiliate within the 3 months following the start of their activity, they are automatically affiliated with LAMal and, if the delay is not excusable, must pay a premium surcharge ([KVG/LAMal, art. 5 para. 2](https://www.fedlex.admin.ch/eli/cc/1995/1328_1328_1328/fr#art_5)):

-   **30% to 50% of the premium** — the insurer sets the rate according to the insured person's financial situation;
-   **less than 30%** — if paying the surcharge would cause the insured person hardship, taking fair account of their situation and the circumstances of the delay.

This surcharge applies for a period equal to **twice the delay in affiliating**, **up to a maximum of five years** ([KVV/OAMal, art. 8](https://www.fedlex.admin.ch/eli/cc/1995/3867_3867_3867/fr#art_8)).

**Worked example** — a 120-day delay (4 months), a LAMal premium of 200 CHF, a 30% surcharge:

-   Increased premium: 200 CHF + 30% = **260 CHF/month**;
-   Duration of application: **8 months** (twice the delay);
-   Increased cost: 260 CHF × 8 = **2,080 CHF**, versus 1,600 CHF without the surcharge.

So the real penalty here is limited to **480 CHF**.

### Retroactivity: two cases to distinguish

-   **Affiliation within the 3-month deadline:** affiliation takes effect on the start date of the employment contract and premiums are due **retroactively** from that date. There is therefore no point in waiting until the end of the deadline to affiliate.
-   **Affiliation after the deadline:** the elapsed months are **not claimed** retroactively, but the premium surcharge applies for a period corresponding to twice the delay, up to five years.

## 5\. How can you optimise the cost of premiums paid in euros?

Changing insurance has a direct impact on your cross-border cash flow, because premiums and contributions are not paid in the same currency as your salary. Optimising the exchange rate on each transfer prevents the cost of your cover from being artificially inflated. Before each due date, you can also [follow the real CHF/EUR market rate](https://www.ibani.com/en/currency-converter/chf-to-eur-rate) to estimate precisely the amount you need to transfer.

-   **Paying in euros:** if you opt for the French CMU, the German GKV/PKV or voluntary SSN contributions in Italy, you must pay these in euros. Your salary, however, is paid in Swiss francs (CHF), so a currency transfer is required.
-   **The cost of traditional banking:** transferring CHF to EUR via traditional banks subjects you to hidden exchange-rate margins (often 1.5% to 3%) and transfer fees, artificially inflating the cost of your healthcare.

💰 Worked example: a 300 EUR monthly premium

To pay a national premium of 300 EUR, ibani converts the exact amount from your Swiss salary account at the real interbank market rate (reference rate around 0.921), plus a margin of 0.40% for amounts under CHF 10,000, i.e. about 1.20 EUR. Where a bank applying a 2% margin would cost you the equivalent of roughly 6 EUR extra every month, the difference is about 4.80 EUR a month, or close to 58 EUR over a year of premiums.

**💡 The ibani solution:** convert your Swiss francs to euros at the real rate, plus a margin of 0.40% to 0.15% depending on the amount, to pay your CMU, GKV or SSN contributions while limiting currency conversion costs.

## Frequently Asked Questions — Changing LAMal / national insurance

### What happens if I miss the 3-month deadline after my change of situation?

If you fail to submit the fully validated exemption form within the strict 3-month window following your status change (new hire after unemployment, moving or retirement), the Swiss cantonal authorities will automatically affiliate you with the Swiss LAMal system. You then remain affiliated with LAMal: the choice can only be revisited at a new change of situation that reopens the right of option.

### Does switching from a part-time to a full-time contract justify a new choice?

No. Modifying your working hours (from part-time to full-time, or vice versa) or simply changing employers without a period of subsidized unemployment in your home country does not constitute a valid change of situation. The right of option remains closed.

### Does changing employers in Switzerland reopen the right of option?

No. A new Swiss employment contract that directly follows a previous Swiss job, with no interruption (in particular without a period of subsidized unemployment in your country of residence), does not reopen the right of option. Your initial choice between LAMal and your national system remains in force.

### How does the right of option work after a period of unemployment in your country of residence?

During subsidized unemployment, the cross-border worker is compulsorily affiliated with the national social security system of their country of residence. When they resume work in Switzerland, this contract counts as a new start of activity: the right of option reopens and they have 3 months to choose between LAMal and their national system.

### How do I pay Euro health premiums while earning my salary in Swiss francs?

CMU, GKV or voluntary SSN premiums are billed in euros, while your salary is paid in Swiss francs (CHF). To avoid the hidden exchange-rate margins of traditional banks, you can convert your CHF to EUR at the real market rate, plus a margin of 0.40% to 0.15% depending on the amount, using a platform like ibani, preserving your purchasing power.

### What penalty applies if you affiliate late with health insurance?

Once the 3-month deadline has passed, the cross-border worker is automatically affiliated with LAMal and, if the delay is not excusable, must pay a premium surcharge of 30% to 50%, set by the insurer according to their financial situation (less than 30% if paying it would cause hardship), for a period equal to twice the delay, up to a maximum of five years. On the other hand, the months of delay are not billed retroactively, so the financial impact remains limited.
