How do you terminate an employee in Luxembourg in 2026?
Cross the five-year mark in Luxembourg and severance switches on: 1 month at five years' service, climbing to 12 months once an employee passes thirty years. That payment sits on top of notice of up to 6 months, and the labour court sets the bill for an unfair dismissal with no fixed ceiling in the law.

Notice in Luxembourg tracks length of service. It runs 2 months below five years, 4 months from five years, and 6 months once an employee reaches ten years.
Severance is owed only once an employee has at least five years' service. It pays 1 month at five years and reaches 12 months past thirty years. It comes on top of notice, not instead of it.
Get the dismissal wrong and there is no fixed payout in the law. The labour court decides the damages. The employee has 3 months to file a claim. (Code du travail art. L.124-12)
How much notice must you give a Luxembourg employee?
Notice rises with service. It is 2 months below five years, 4 months from five to ten years, and 6 months at ten years or more.
The dismissal letter must go out by registered post. The notice clock starts on the 15th of the month if you send it in the first half, or the 1st of the next month if you send it later. (Code du travail art. L.124-3)
| Length of service | Employer notice |
|---|---|
| Under 5 years | 2 months |
| 5 to under 10 years | 4 months |
| 10 years or more | 6 months |
These are the floors set by Code du travail art. L.124-3. A contract or a collective agreement can set longer notice. It cannot go below these periods.
How the notice clock starts
You serve notice by registered letter. If the letter is posted in the first half of a month, notice begins on the 15th of that month. If it is posted in the second half, notice begins on the 1st of the following month. That timing rule, not the postmark, fixes the real end date, so always count the start day before you promise an exit date.
Paying notice out
You can release an employee from working their notice and pay it out instead. The pay must cover everything the employee would have earned across the full notice period. It is taxed as normal salary under Luxembourg payroll rules.
What is fair procedure for terminating in Luxembourg?
You need a real, fair and serious reason to dismiss. The grounds split into conduct or performance reasons tied to the person, and economic reasons tied to the business.
For a business with 150 or more staff, you must hold a preliminary meeting before you send the dismissal letter. Skip a required step and the dismissal can be ruled unfair. (Code du travail art. L.124-2)
Luxembourg law requires a cause that is real, fair and serious (cause réelle, sérieuse et légitime). A dismissal without one is open to challenge in the labour court. The reason must rest either on the employee's aptitude or conduct, or on the operating needs of the business.
Valid grounds for dismissal
- Misconduct, where behaviour breaches the duties of the role
- Gross misconduct, serious enough to justify dismissal without notice and without severance
- Poor performance or unfitness, where the employee cannot meet reasonable standards of the job
- Economic reasons, where the role is removed for genuine business needs
- Mutual agreement, where both sides sign to end the contract
Some dismissals are barred outright. You cannot dismiss an employee on sick leave who has filed a valid medical certificate, and a pregnant employee or one on maternity leave is protected from dismissal. Maternity leave runs to 20 weeks in total, split as 8 weeks before the birth and 12 weeks after. Dismissals tied to a protected ground are unfair from day one. (Code du travail art. L.332-1)
Stating the reason in writing
If the employee asks, you must give the precise grounds for the dismissal in writing. Vague or shifting reasons weaken your position if the case reaches the Tribunal du travail. Write the grounds out clearly and keep the supporting record.
-
Fix a real and serious reason
Anchor the dismissal to a valid ground, either the employee's conduct or aptitude, or a genuine business need. A dismissal without a real, fair and serious cause is open to challenge.
-
Hold the preliminary meeting where required
If the business has 150 or more employees, invite the employee to a preliminary meeting before you send the letter. Record what was discussed.
-
Serve notice by registered letter
Send the dismissal letter by registered post. Watch the timing rule that decides when the notice clock starts, because it moves the real exit date.
-
State the grounds in writing if asked
Give the precise reason for the dismissal in writing when the employee requests it. Keep the supporting evidence in case the matter reaches the labour court.
-
Calculate notice, severance and final pay
Work out the notice band, the severance owed once service passes five years, and the accrued leave payout. Settle them on the next monthly payroll run.
How is Luxembourg severance pay calculated?
Severance starts at five years' service. There is none below that mark.
It pays 1 month from five years, 2 months from ten years, 3 months from fifteen years, and reaches 12 months once an employee passes thirty years. (Code du travail art. L.124-7)
Severance pay (indemnité de départ) is due to any employee dismissed with notice who has at least five years' service, under Code du travail art. L.124-7. It is paid on top of the notice, not in place of it. Below five years, none is owed.
Severance by length of service
| Length of service | Severance (months of salary) |
|---|---|
| Under 5 years | None |
| 5 to under 10 years | 1 month |
| 10 to under 15 years | 2 months |
| 15 to under 20 years | 3 months |
| 20 to under 25 years | 6 months |
| 25 to under 30 years | 9 months |
| 30 years or more | 12 months |
The amount is built from the employee's gross monthly pay over the months before the dismissal. A long-serving senior hire can therefore carry a large severance bill, since both the months owed and the salary base climb with tenure.
Gross misconduct
A dismissal for gross misconduct (faute grave) ends the contract on the spot. No notice is worked and no severance is owed. The bar is high, and a court that disagrees can reclassify the exit and order both notice and damages.
Trial period
An employee in their trial period is not owed severance. The trial runs from a minimum of 2 weeks to a standard maximum of 6 months, and out to 12 months for a high earner. That last band is the trap. A senior hire on a long trial can be ended cheaply early, then becomes far more costly to exit once the trial closes.
Are there extra rules for group redundancies in Luxembourg?
Yes. An economic dismissal of several employees triggers a formal information-and-consultation process with staff representatives.
A plan to cut seven or more posts over thirty days, or fifteen or more over ninety days, is a collective redundancy and needs a negotiated social plan.
A collective redundancy in Luxembourg means at least seven dismissals on economic grounds within thirty days, or at least fifteen within ninety days. The employer must open negotiations on a social plan (plan social) with the staff delegation and notify the ITM and the national employment agency (ADEM) before any letter goes out.
The social-plan negotiation must run in good faith before any dismissals take effect. It covers selection criteria, redeployment, retraining and the terms of departure. Starting the dismissals before the process closes exposes the whole group to challenge.
What the consultation must cover
- The reasons for the planned redundancies
- The number and categories of employees affected
- The criteria used to select who leaves
- Measures to limit the cuts, such as redeployment or retraining
- The timeline and the terms of departure
Each affected employee still keeps their individual rights to notice and, where they qualify, severance. The collective process sits on top of those individual entitlements, it does not replace them.
Can you agree a mutual exit in Luxembourg?
Yes. Both sides can end the contract by mutual agreement (résiliation d'un commun accord).
The agreement must be in writing and signed by both parties. It sidesteps the notice and severance rules, so the terms are whatever you negotiate.
A mutual termination ends the contract by consent rather than by dismissal. It must be set down in writing and signed by both the employer and the employee. Because no dismissal is involved, the notice ladder and the severance scheme do not apply, and the departure terms are open to negotiation.
Typical components of a Luxembourg mutual exit:
- An agreed leaving date, fixed in the document
- A negotiated exit payment, often benchmarked against what notice and severance would have cost
- Accrued annual leave, paid out for the 26 days statutory entitlement and any contractual days unused
- A reference, with wording agreed in advance
- Confidentiality terms, where commercially sensible
One point to weigh. An employee who signs a mutual termination usually cannot claim unemployment benefit from ADEM straight away, which is why the exit payment is often the deciding factor in the negotiation.
On final pay timing, salary is paid monthly and is due at the latest on the last calendar day of the relevant month. Settle the final salary, the leave payout and any agreed sum on the normal payroll run that follows the leaving date, and get the agreement signed before the last working day to avoid a dispute over the figures.

Frequently asked questions
How much notice must you give a Luxembourg employee in 2026?
Employer notice rises with length of service under Code du travail art. L.124-3. It is 2 months for under five years, 4 months from five to under ten years, and 6 months at ten years or more. You serve it by registered letter, and the notice clock starts on the 15th or the 1st depending on when you post it. You can pay the notice out instead of working it.
Is severance pay mandatory in Luxembourg?
Only from five years' service. An employee dismissed with notice who has at least five years earns 1 month of severance, rising to 2 months from ten years, 3 months from fifteen years, and 12 months once they pass thirty years. Severance is paid on top of notice, and none is owed below five years or for dismissal on grounds of gross misconduct.
What happens if a Luxembourg dismissal is unfair?
There is no fixed compensation amount in the law. The labour court (Tribunal du travail) assesses the damages, covering the lost pay and any moral harm. The employee has 3 months from the dismissal to file the claim under Code du travail art. L.124-11. A dismissal tied to a protected ground, such as pregnancy or valid sick leave, is unfair regardless of length of service.
What is the maximum trial period in Luxembourg?
The trial period (période d'essai) runs from a minimum of 2 weeks to a standard maximum of 6 months for an employee with a CATP/DAP-level qualification or higher. It extends to 12 months for an employee earning at least EUR 5,188.69 gross per month at the current index. No severance is owed during the trial period.
Does accrued annual leave get paid out on termination in Luxembourg?
Yes. Any unused annual leave is paid out when the contract ends, whatever the reason. The statutory entitlement is 26 days of paid leave per year for full-time employees. The outstanding balance is a cash liability settled on the final payroll run, which falls at the latest on the last calendar day of the relevant month.
When do group redundancies trigger extra rules in Luxembourg?
A collective redundancy arises when an employer plans at least seven dismissals on economic grounds within thirty days, or at least fifteen within ninety days. The employer must negotiate a social plan with the staff delegation and notify the ITM and ADEM before any dismissal takes effect. Each affected employee keeps their individual notice and, where they qualify, severance on top.
The Luxembourg mistake we see most is assuming severance is owed from day one. It is not. It switches on at five years, then climbs with tenure on top of notice. The other trap is the registered-letter timing rule, which quietly moves the exit date employers thought they had agreed.
Luxembourg holds severance back until an employee hits five years, then pays 1 month and keeps climbing to 12 months past thirty.
Most employers budget for notice and forget the severance sits on top of it.
And an unfair dismissal here has no fixed price. The labour court sets the bill.
