Last updated: 16/12/2025

An employee seconded to Monaco remains covered by the French social security system; businesses not established in Monaco must obtain permission for a worksite. There are two different procedures for seconding employees, depending on how long they will be working in the Principality.

Understanding the process

Thanks to the secondment procedure, an employee from France, who comes to work in Monaco for a specific period on behalf of your company, will remain registered within the French social security system.

For secondments:

For periods of less than 3 months, the procedure is to be carried out via the dedicated online service by following the steps below
For periods of more than 3 months, you should contact the Employment Office to submit a paper application.

Businesses, craftspersons or subcontractors not established in Monaco and who wish to carry out work on public or private sites must first apply to the Business Development Agency. See: How to request permission for a worksite.

This online service is not intended for craftspersons authorised to work alone, without seconding employees. You can inform the Employment Office by post, explaining that you are working alone, and enclosing a copy of the work permit issued by the Business Development Agency.

To obtain the form "SE/138-01 – Certificat d’assujettissement", access the dedicated service via the following means:

On your Net-Entreprises online account, the DAE service will be automatically replaced by the new ILASS service without any action on your part
On your Urssaf.fr online account, in the "Services en 1 clic", menu under "Travail à l’étranger"

You must submit one copy of the form to:

Your employee at the moment of his/her departure (he/she must retain this copy during the secondment)
To the relevant CPAM for information purposes, within 24 hours of the beginning of the secondment period

For secondments of employees to work on construction sites, you will be asked to submit a site authorisation issued by the Business Development Agency.

This request may be submitted online. Please click on the following link: How to second an employee to Monaco for less than three months.

Once your application has been approved, you will receive an email officially authorising the employee concerned to work in Monaco on secondment. You must provide them with a copy of this email, so they can produce it for the relevant authorities if needed.
