SQUARRELIn Luxembourg, some company directors are treated as self-employed for social security purposes, even though their remuneration is classified for tax purposes as income from employment and is subject to wage withholding tax. This tax treatment does not, on its own, make them employees within the meaning of labour law.
In brief:
A company director is not necessarily an employee in Luxembourg.
They may be registered as self-employed with the CCSS (Centre commun de la sécurité sociale), while receiving remuneration classified for tax purposes as income from employment.
Employee status within the meaning of the Labour Code, for its part, requires duties distinct from the corporate office and a genuine relationship of subordination.
In Luxembourg, self-employed status does not only concern sole traders, craftspeople, merchants or the liberal professions. Some company directors are compulsorily treated as self-employed for social security purposes, even though they receive a monthly remuneration subject to wage withholding tax.
This separation between social security law, tax law and labour law is essential. Owning a company, issuing a payslip or having a document entitled “employment contract” is not, on its own, enough to determine the director’s status.
Which directors are registered as self-employed?
The self-employed scheme applies first of all to persons who carry out, in Luxembourg and on their own account, a commercial, craft, agricultural or mainly intellectual and non-commercial activity.
The Social Security Code, however, extends this scheme to certain directors who carry out their activity through a company.
In a société en nom collectif, a société en commandite simple, a SARL or a SARL-S, the shareholder-manager is treated as self-employed when they personally hold more than 25% of the shares and are the holder of the company’s business permit (autorisation d’établissement).
The statutory threshold is strict: a shareholding of exactly 25% is not enough. Nor does the text provide for adding together the holdings of the spouse or other family members.
In an SA, a société en commandite par actions or a cooperative society, board members, general partners or authorised representatives are treated as self-employed where they are both:
- delegated to day-to-day management;
- and the persons on whom the business permit is based.
Being a board member or the holder of the business permit is therefore not enough on its own: the duties actually performed must also be examined. These criteria derive from Article 1 of the Social Security Code. (igss.gouvernement.lu)
Self-employed for social security purposes, employment income under the LIR
The expression “self-employed employee”, which is sometimes used, is convenient but legally imprecise.
A director may at the same time be:
- treated as self-employed for social security purposes;
- taxed under the category of income from employment;
- without employee status within the meaning of the Labour Code.
Indeed, Article 95, paragraph 6 of the Income Tax Law classifies as income from employment the remuneration paid to board members and to persons performing similar functions where it is granted in respect of the day-to-day management of the company. This remuneration is therefore subject to wage withholding tax, even if its recipient falls under the social security scheme for the self-employed. (impotsdirects.public.lu)
A payslip may therefore be prepared in order to determine the gross remuneration, any benefits, tax credits, the tax withheld and the net amount to be paid. Its existence, however, proves neither the existence of an employment contract nor that of a relationship of subordination.
The corporate office is not, in itself, an employment contract. Holding both is only possible if the director performs genuine salaried duties, distinct from their office, under the effective authority of a body that has powers of direction, control and sanction over them.
The Court of Cassation has confirmed that the existence of an employment contract requires proof of a relationship of subordination, and that a person’s participation in the shareholding or the management of the company calls for a concrete examination of the powers of direction and control exercised over them. The mere formal appearance of an employment relationship is therefore not enough to establish that classification¹.
In the absence of a genuine, separate employment contract, the director does not, by virtue of their office alone, enjoy the rights attached to the Labour Code, notably in respect of paid leave, dismissal, notice or severance pay.
Registration and calculation of social security contributions
The activity must be declared to the Centre commun de la sécurité sociale within eight days of its commencement. A practical peculiarity: a director treated as self-employed through a company uses the registration form normally intended for employees. The form used does not, however, change the social security classification recorded by the CCSS. (ccss.public.lu)
Contributions are calculated on the self-employed person’s professional income. On first registration, the CCSS provisionally uses the social minimum wage, unless a more realistic estimate is provided. For a self-employed activity carried on alongside salaried employment, the provisional basis is in principle one third of the social minimum wage.
The final income is only determined once the tax data have been communicated by the Administration des contributions directes. A retroactive adjustment is then made. It is therefore advisable to adjust the provisional basis as soon as annual income can be reliably estimated, in order to avoid a large call for contributions several years later. (ccss.public.lu)
Since 1 June 2026, the monthly minimum contribution base has been EUR 2,771.33 and the ceiling EUR 13,856.63. These limits apply in particular to sickness, pension and accident insurance. The long-term care contribution has neither a minimum nor a ceiling, and its base is reduced by an allowance equal to one quarter of the social minimum wage. (ccss.public.lu)
The rates applicable to the self-employed in 2026 are as follows:
- Sickness insurance – healthcare: 5.60%
- Sickness insurance – cash benefits: 0.50%
- Pension insurance: 17.00%
- Long-term care insurance: 1.40%
- Accident insurance: 0.5525% to 0.9750%
- Mutualité des employeurs, optional: 0.23% to 2.66%
With an accident insurance rate of 0.65%, the nominal total of compulsory contributions comes to 25.15%. This percentage cannot, however, be applied mechanically to any remuneration: the long-term care base is different, the accident rate varies and the rules on minimum and maximum amounts must be taken into account. (ccss.public.lu)
Who has to pay the contributions?
The self-employed person is personally liable for their contributions. These are invoiced directly by the CCSS and are not, in principle, withheld on the payslip issued by the company.
The mere fact that payment is physically made from the company’s bank account does not determine its accounting and tax treatment. The amount paid on the director’s behalf must be correctly classified and recorded in the accounts.
The personal contributions of a partner or shareholder are, in principle, private expenses. They therefore cannot automatically be recorded as deductible expenses of the company. Where the company pays them, they must in particular be treated:
- as an advance or receivable booked to the director’s current account;
- or as an additional element of remuneration that is duly authorised, declared and subject to the appropriate tax withholding.
In the absence of appropriate treatment, the payment may notably be regarded as a benefit granted to the shareholder or as a hidden profit distribution within the meaning of Article 164, paragraph 3 LIR. The repeal, in July 2023, of former LIR Circular No. 46/2 therefore did not prohibit the use of the company’s bank account; it removed the administrative tolerance that previously allowed, under certain conditions, the company to deduct these contributions. (impotsdirects.public.lu)
Tax deduction for the director
Compulsory contributions borne by a non-employee for sickness, accident and pension insurance are deductible without limit as special expenses, in accordance with Article 110, No. 2 LIR. The long-term care contribution, on the other hand, is not deductible for income tax purposes. (impotsdirects.public.lu)
The director may ask for the expected contributions to be entered on their tax withholding card using form 164. This reduces the basis used to calculate the monthly withholding and avoids having to wait for the final assessment to benefit from the deduction.
Self-employed status for social security purposes does not, however, automatically make it compulsory to file an annual tax return. This obligation depends on the nature and amount of the income and on the other criteria for assessment. A return is nevertheless often necessary or advisable in order to regularise the contributions actually paid and to take account of the taxpayer’s other income and deductions.
Social protection close to, but not identical with, that of an employee
The self-employed person is compulsorily covered for sickness-maternity, pension, accident and long-term care risks. They may also join the Mutualité des employeurs on a voluntary basis.
During the period in which the sickness cash benefit paid by the CNS is suspended — in practice, approximately the first 77 days of temporary incapacity for work — the Mutualité reimburses 80% of the contribution base. During that period, it also covers leave for family reasons and end-of-life care leave. (ccss.public.lu)
Lastly, the self-employed person may receive full unemployment benefit in the event of the involuntary cessation of their activity, under conditions specific to their status. In particular, they must prove at least two years of compulsory affiliation to Luxembourg social security, have carried on a self-employed activity for at least six months and submit their application to ADEM within six months of the cessation. The prior existence of an employment contract or a relationship of subordination is not required to access this specific scheme. (adem.public.lu)
The key point to watch
The legal form of the business does not, on its own, determine the director’s social security status. The sole shareholder of a SARL may be self-employed despite the existence of payslips, while a minority manager does not automatically become an employee either.
Correct classification requires checking, together:
- the exact shareholding;
- the identity of the person on whom the business permit is based;
- the management duties actually performed;
- the possible existence of a genuine relationship of subordination;
- the registration recorded with the CCSS;
- and the tax and accounting treatment of the remuneration and contributions.
An inconsistency between the articles of association, the business permit, the CCSS registration and the remuneration documents may go unnoticed for several years and then lead to significant social security, tax and accounting adjustments.
