Inability to work in Luxembourg: what happens if you can't work anymore?

The first 77 days: your employer pays

When you're on sick leave in Luxembourg, your employer is required to maintain 100% of your salary for the first 77 days of incapacity over a reference period of 18 months. This is called salary continuation.

During this period, you must meet certain obligations: send your medical certificate on time, respect authorised going-out hours, and submit to any CMSS checks.

Once day 77 is reached, your employer still pays until the end of that month. From the following month, they're no longer required to pay you: the CNS takes over.

The CNS cash sickness benefit

From the following month, the Caisse nationale de santé (CNS) pays you a cash sickness benefit. The amount roughly corresponds to your gross salary, capped at 5 times the social minimum wage.

The limit is 78 weeks of incapacity over a reference period of 104 weeks, and those 78 weeks include the days already paid by your employer: the CNS doesn't add them on top. In total, that's about 18 months of coverage from the start of your sick leave.

Throughout this period, the CMSS (Social Security Medical Control) monitors your case. They decide whether you're fit to return to work, need reclassification, or qualify for an invalidity pension.

Meanwhile, your healthcare costs get reimbursed by the CNS.

What happens when payments end

When the cash sickness benefit expires, the CMSS issues an opinion. Several scenarios are possible.

Scenario 1: you're fit to return

The CMSS declares you fit before your entitlement runs out. You return to work. If your employer has in the meantime terminated your contract (which is possible after 26 consecutive weeks of absence), you'll need to find a new position. Be careful: on the day you use up your 78 weeks of benefit, your employment contract ends automatically, without any dismissal, and you can no longer return to that job.

Scenario 2: professional reclassification

The CMSS finds that you can no longer perform your last job but can work in another role suited to your abilities. This is professional reclassification.

There are two types:

Internal reclassification: your employer offers you another position within the company, adapted to your medical situation.

External redeployment: you are guided towards another job through the Agence pour le développement de l’emploi (ADEM).

If the Commission mixte decides on your external reclassification following a work accident, commuting accident or occupational illness, you can apply to the Association d’assurance accident (AAA) for a professional waiting allowance. You must be registered with ADEM, have a permanent partial incapacity of at least 10% (accidents since 1 January 2017) and apply within 3 years of your condition being declared stable (consolidation).

This amounts to 85% of the full pension (rente complète), itself calculated on your contributory income over the 12 months before the accident or occupational illness.

Scenario 3: invalidity pension

If the CMSS finds that you can no longer perform any professional activity matching your abilities, you can apply for an invalidity pension from the CNAP (ouvre dans un nouvel onglet).

A dismissal may follow: know your rights under labour law.

The invalidity pension: conditions and amount

Conditions

To qualify for an invalidity pension, you must meet these criteria:

You are under 65. The CMSS has confirmed your invalidity. You have contributed at least 12 months of mandatory insurance during the 3 years preceding the date of invalidity. This qualifying period is waived if the invalidity results from an accident of any kind (not only a work accident) or from a recognised occupational disease, occurring while you were insured.

You must also give up any professional activity earning more than one third of the social minimum wage.

Amount

The invalidity pension is calculated based on your years of contributions and earnings. It includes flat-rate increases (based on insurance duration, maximum 40 years counted) and proportional increases (based on career earnings).

A special flat-rate increase fictitiously extends your career to age 65, so you're not penalised for stopping work due to health reasons.

If you've contributed at least 480 months (40 years), the minimum pension is €2,436.04 gross per month (amount as of 1 June 2026).

In practice, if you had a comfortable salary, the invalidity pension will only cover a fraction of your income. That's where a private loss-of-income insurance can make a real difference.

At 65, the invalidity pension is automatically converted into an old-age pension.

Loss-of-income insurance: the private safety net

The legal protection (salary continuation + CNS benefit + possibly invalidity pension) often leaves a significant gap between your former income and what you actually receive.

A loss-of-income insurance (also called incapacity insurance) is a private contract that pays you a daily allowance if you're unable to work. It compensates for the difference between your legal coverage and your usual income.

This type of insurance is particularly relevant for self-employed workers and liberal professions, who don't have salary continuation from an employer. But employees with significant fixed costs (mortgage, family) also have good reason to look into it.

Premiums for loss-of-income insurance are generally tax-deductible under article 111 L.I.R., just like supplementary health insurance premiums.

An insurance advisor can help you assess the right level of coverage based on your personal situation.
