Practical guide
Every private-sector employer in France must offer top-up health cover and pay at least half of it. What you pay on your payslip, why even the employer's share trims your net pay, when you can opt out and what happens when you leave: examples worked out by the site.
On your payslip, the health cover line is one of the few contributions whose amount depends not on your salary but on the contract your company chose. It is compulsory, at least half funded by the employer, and it has two effects on your net pay that few employees know about. This guide sets out the rules, shows those effects in examples calculated by the site, and says when you can do without it.
Every private-sector employer, company or association, must offer group top-up health cover to all its employees, whatever their length of service; only private individuals employing domestic staff are exempt. It must pay at least 50% of it. The contract must cover a minimum basket of care: the patient's share (ticket modérateur) of reimbursed care, the daily hospital charge, part of dental prostheses and orthodontics, and an allowance for glasses. It is set up by a sector agreement, a company agreement or, failing that, an employer decision.
Your share appears among the health contributions, often labelled “complémentaire santé”. It is withheld from your gross pay like a contribution, but its amount is set by the contract, usually unrelated to your salary: two colleagues on very different salaries pay the same. The employer's share also shows on the payslip, in the employer column. The guide to your payslip explained places this line among the other contributions.
Non-cadre employee on €3,000 gross a month. Four situations, worked out by the site's engine:
| Situation | Total premium | Your share | Take-home pay | Taxable pay | Employer cost |
|---|---|---|---|---|---|
| No company cover (opt-out) | — | — | €2,375 | €2,460 | €3,987 |
| Standard contract, split equally | €40 | €20 | €2,353 | €2,459 | €4,007 |
| Contract twice as expensive, split | €80 | €40 | €2,331 | €2,458 | €4,027 |
| Standard contract, employer pays all | €40 | — | €2,371 | €2,498 | €4,027 |
Two effects show up. First, your share comes off your net pay, with a small extra cost: with the standard contract, your net pay falls by €22 for a share of €20, because the employer's share bears CSG and CRDS. Second, that employer share counts in your taxable pay: even when the employer pays for all of it, the cover costs you €4 net a month and adds €38 to your taxable income. To redo the calculation with your own premium, the gross-to-net converter has a “Health cover, employee share” field in its options.
Joining is compulsory, except in specific opt-out cases that you must request yourself, usually when you are hired or when the plan is introduced:
An opt-out is not an automatic saving: without company cover, you lose the employer's share and must cover yourself, often at a higher price for the same benefits.
The employer's obligation concerns your own cover. Cover for your partner and children is optional: many contracts offer it as an option, at a family rate towards which the employer does not necessarily contribute. Likewise, extra cover or options (glasses, dental, alternative medicine) may be offered, usually at your expense. Before signing up, compare the price and benefits with an individual policy.
If your contract ends for a reason other than gross misconduct (faute lourde) and you are entitled to unemployment benefit, your company cover is kept during the benefit period, within the length of your last contract and a cap set by law: this is called portability. You must show the insurer that you are receiving unemployment benefit, and tell it when that stops. On retirement, the insurer must offer to keep you covered on an individual basis, at your own expense. The guide to unemployment and pay explains what you will receive during that period.
Better-funded health cover, or a good family contract, is worth money every month: ask for the table of benefits and the price before you sign, especially if you have a family to cover. On the employer's side, health cover is part of the total cost, just like gross pay: in our example, paying for the whole standard contract costs it €20 more a month. The guide to the cost of an employee and the employer cost tool break that cost down. And to compare two offers with different health cover, the job offer comparison tool accepts a different employee share for each.
Only in the set opt-out cases: already covered as a dependant by another compulsory group contract, an individual policy running until its renewal date, receiving the state top-up cover (complémentaire santé solidaire), or short fixed-term or part-time contracts under the rules of the act that set up the plan. You apply when you are hired or when the plan is introduced, with proof where required.
At least 50% of the basic contract's contribution, for the employee's own cover. It may pay more, up to all of it; a collective or company agreement sometimes provides for that. Options and family cover, on the other hand, may stay at your expense.
Yes. The employer's share of health cover is added to your taxable pay and bears CSG and CRDS. That is why your taxable pay exceeds your take-home pay by a little more than the non-deductible CSG alone, and why health cover paid entirely by the employer still trims your net pay slightly.
Not necessarily: covering dependants (partner, children) is optional for the employer. Many contracts offer it as an option, at a family rate often at your expense. Compare it with an individual policy for your family before choosing.
