Wage Garnishment in Luxembourg: Employer’s Obligations and Role
Notification and the Affirmative Declaration
It all begins with the receipt of a registered letter or a bailiff’s writ. From this date, you have a strict period of 8 days to provide what is known as an affirmative declaration.
- The status of contractual ties: Is the debtor still an employee of the company?
- The amount of remuneration: What is their net salary?
- The existence of other garnishments: Are there already other creditors involved?
- Voluntary assignments: Has the employee already assigned a portion of their salary (consumer credit, etc.)?
Receiving a wage garnishment order for one of their employees is never a preferred moment for an HR manager or company director. However, in Luxembourg, the employer plays a central and mandatory role as a “garnishee.” This is not a mere formality: your legal responsibility is engaged upon receipt of the letter from the Justice of the Peace Court.
Calculating the Garnishment Amount
This is where things get technical. You cannot garnish the entire salary. Luxembourgish law protects the employee to guarantee them a “living wage.” The calculation is based on income brackets defined by Grand-Ducal regulation.
The net salary is divided into five brackets. For each bracket, a specific percentage can be deducted. The formula for determining the garnishable portion $S$ on an income bracket $R$ with a rate $t$ can be expressed as follows:
(Where R_i represents the portion of the salary within bracket i and t_i is the rate applicable to that bracket).
Payment and Monitoring Obligations
Once the calculation is made, the employer must withhold the sum each month and pay it either to the creditor or to the court registry, according to the instructions received. Please note: wage garnishment generally takes precedence over salary assignment, except in specific cases.
- Monthly payment: It must be regular and correspond to the bracket calculation.
- Information: If the employment contract ends (resignation, dismissal), you must inform the creditor and the Court.
- Responsibility: If you neglect to make the deduction, you could be ordered to pay the garnished amounts yourself!

What to Remember to Remain Compliant
The employer does not have to judge the merits of the debt. Their role is purely executive. To avoid any disputes with your employee or with the justice system, keep these three pillars in mind:
- Responsiveness: Respect the 8-day deadline for the initial declaration.
- Accuracy: Use the updated official scales (brackets are regularly indexed).
- Confidentiality: Wage garnishment is sensitive data. Only HR and accounting departments should be informed to comply with GDPR.
