Student job pay in Luxembourg: contract and 80 % of SSM
A student's summer job is not a discount fixed-term contract: it is a contract of its own, with its age range, duration, pay floor and social regime. An employer who confuses it with an ordinary contract pays too much, or too little.
Direct answer
A pupil or student aged 15 to 27 may be employed during school holidays under the pupil and student employment contract of the Labour Code (articles L.151-1 to L.151-8), for at most two months per calendar year across all employers. Pay may not be lower than 80 % of the social minimum wage (SSM), graded by age. The student is only affiliated to accident insurance, and the pay is exempt from wage tax withholding on the employer's request when gross hourly pay does not exceed EUR 16.
Outside school holidays, or beyond two months, there is no student contract any more: the employment falls under an ordinary employment contract, fixed-term or not, with the full social minimum wage and all contributions.
Conditions of the student contract
The beneficiary is enrolled in a Luxembourg or foreign educational establishment and regularly follows a course of study, or their studies ended less than four months earlier (article L.151-1 of the Labour Code). Age is assessed at the contract date: at least 15, at most 27.
The contract is in writing, drawn up in three copies at the latest when work starts, and the employer sends a copy to the Labour and Mines Inspectorate (ITM) within seven days (articles L.151-3 and L.151-4). It states the nature of the work, duration, schedule, place and pay. A verbal contract, or one signed at the end of the assignment, forfeits the regime: the employment is then reclassified as an ordinary employment contract.
The maximum duration is two months per calendar year, or 346 hours, including when the student works for several employers in a row (article L.151-2). The employer has to check it; a statement signed by the student on earlier employment in the year is the simplest practice.
Pay: 80 % of the social minimum wage
Article L.151-6 of the Labour Code sets the floor: at least 80 % of the applicable social minimum wage, graded by age (the minimum wage of workers under 18 is itself reduced). The amount of the social minimum wage follows the cost-of-living index and changes at each index step; the employer reads the rate in force on the website of the Joint Social Security Centre (CCSS) at the time of the contract, never in a dated article.
Nothing prevents paying more. The floor is computed on the hourly rate of the unskilled social minimum wage, even if the student holds a diploma: qualification is only assessed under an ordinary employment contract.
The payslip remains mandatory, as for any employee; our page on payroll in Luxembourg details the required items and the monthly declaration.
Social charges and tax
A student under an employment contract is not affiliated to pension or health insurance for that employment: only accident insurance is due, borne by the employer, after an entry declaration to the CCSS under the code reserved for pupils and students. The student remains covered for health through their own status as insured or co-insured (dependant of their parents).
On the tax side, the pay is in principle subject to wage tax withholding. The employer may request a withholding exemption from the competent RTS tax office when gross hourly pay does not exceed EUR 16; the request is made by form, for each student, before the first payment. Above EUR 16 an hour, withholding applies according to the student's tax card, and any overpayment is recovered through the income tax return or the annual adjustment.
Student contract, internship, fixed-term: three regimes
Three situations look alike on the ground and are not handled the same way. Confusing them is the most frequent payroll error among employers hosting young people for the summer.
| Regime | Basis | Duration | Pay | Social security |
|---|---|---|---|---|
| Student contract (holidays) | art. L.151-1 to L.151-8 Labour Code | 2 months or 346 h per calendar year | At least 80 % of the SSM, graded by age | Accident insurance only |
| Practical internship | law of 4 June 2020 | Per the agreement, statutory caps | Mandatory allowance beyond four weeks, as a percentage of the SSM | Depends on duration and allowance |
| Ordinary fixed-term contract | Book I, Title II Labour Code | Per the contract, fixed-term caps | Full SSM, skilled or unskilled | Full affiliation |
What the employer must keep
A summer student's file holds five documents: the written contract in three copies, the copy sent to the ITM, proof of pupil or student status, the entry and exit declarations to the CCSS, and, where applicable, the withholding exemption request filed before the first salary. A correctly configured monthly payroll does the rest.
For a first hire, the configuration of the affiliation code and of the withholding exemption is where errors happen; our payroll team handles it within the payroll mandate, and the firm's accountant picks the charge up in the closing.
