Introduction
One of the most important choices a cross-border worker has to make as soon as they start working in Switzerland concerns their health cover.
This choice, known as the right of option, commits you for the long term. It sets two very different schemes against each other: the French CMU and the Swiss LAMal.
This choice is not just an administrative formality. It directly affects your level of reimbursement, the cost of your health protection, your access to care in Switzerland, and your pension rights.
And above all, it is final, except in the event of a major change of situation.
In this article, we help you see things clearly with a detailed comparison, real cases and practical advice.
LAMal vs CMU comparison
Here is a summary table of the main differences between the 2 schemes:
| Criterion | LAMal | CMU |
|---|---|---|
| Contribution | Flat rate (~220 CHF/adult) | 8% of N-2 income |
| Basis of calculation | Per person | Per household |
| Access to care in Switzerland | Full | Very limited |
| Reimbursement in France | Through top-up cover | French Sécurité sociale |
| Taxation | Deductible | Deductible |
| Attractive for... | Single people, high earners, care in CH | Large families, modest incomes |
This table shows that the choice does not depend on a single criterion, but on a set of personal parameters: income level, household composition, medical habits, preferred place of care, and so on.
Real-life cases
These examples illustrate the concrete differences between the two schemes according to typical profiles.
Sophie, 35, single with a salary of 120 000 CHF/year
With the CMU, her contribution would be around 8 000 € a year, against around 2 500 CHF/year with the LAMal. As she needs regular access to care in Switzerland, the LAMal is the obvious choice.
Julie and Marc, a couple with three children, Marc working in Switzerland (45 000 CHF/year) and Julie in France (20 000 €/year)
With the CMU, they contribute around 3 000 € for the household, the children being covered under the parents. With the LAMal, they would pay around 4 000 CHF for Marc and the children. In their case, the CMU is financially more advantageous.
Patrick and Nicole, a couple with two children, both working in Switzerland (160 000 CHF/year of combined income)
With the CMU, they would have paid around 12 000 €/year. Whereas with the LAMal, they would have paid around 6 500 CHF/year with the children.
Antoine, 45, a cross-border worker for ten years, with frequent medical follow-up in Geneva
Antoine had chosen the CMU at the time, but today regrets not having opted for the LAMal. Unfortunately, since the right of option is closed, he can no longer go back on his decision.
Tips for making the right choice
To choose well between the LAMal and the CMU, it is essential to follow a structured approach. Here are a few markers to keep in mind:
- Work out your N-2 reference tax income and estimate the CMU contribution from it. That gives you an objective comparison with the annual cost of the LAMal.
- If you want regular access to care in Switzerland, the LAMal is more appropriate: it saves you refusals of cover or unreimbursed costs.
- If you are in a couple with children and your income is modest, the CMU may turn out to be cheaper thanks to its per-household contribution.
- Watch the deadline: you have only 3 months after starting your job to make this choice. After that, the authorities consider that you have opted by default for the LAMal.
- Take advice before signing the form. Once approved, this document commits your health cover for years.
And at retirement? A new option opens up
When you retire, your situation changes. You become a full-time resident in France, which reopens the right of option.
| Situation | Scheme applicable at retirement |
|---|---|
| Swiss pension only | Free choice between the CMU and the LAMal |
| Swiss + French pension | Compulsory Sécurité sociale, through the CSG-CRDS (9.1% of all income) |
This means that even if you were affiliated to the LAMal during your working life, you will be able to choose again at retirement, or be required to, depending on your rights in France.
If you receive only a Swiss pension and continue to see doctors in Switzerland, the LAMal remains an attractive solution, even in retirement.
In 2025, which choice makes the most sense?
There is no universal answer. The right choice depends on a combination of criteria: income, household structure, usual places of care, plans to move, handling of the unexpected.
- The LAMal is generally more attractive for high earners, single people or cross-border workers who want to see doctors in Switzerland.
- The CMU can be more advantageous for households with several children, low or middle incomes, or those who see doctors exclusively in France.
But beware: the biggest pitfall is not comparing the two options seriously, or letting the legal deadline pass without making an explicit choice.
