Most Frequently Asked Legal Questions

• Does a third-country national holding a residence permit (student or resident) in France automatically lose this permit by going to work in Luxembourg?

  No, the French residency permit is not automatically lost just by going to work in Luxembourg. However, the holder must respect certain conditions and procedures to maintain the validity of their French residency permit if they wish to return to live in France later. A prolonged absence from French territory can be a reason for non-renewal or withdrawal of the residency permit.

• How long can I stay outside of France without risking the loss of my residence permit?

  The maximum permitted duration of absence varies depending on the type of residence permit. For a temporary residence permit, an absence of more than six consecutive months outside of France can be considered a break in the ties with French territory. For a long-term resident-EU permit, the absence must not exceed twelve consecutive months outside the European Union, or six years for professional, training, or family reasons in another EU member state.

• Do taxes on income earned in Luxembourg have to be declared in France if the person maintains their tax residence in France?

  Yes, if the person maintains their tax residence in France, they are required to declare all their earned income, including that from professional activities carried out in Luxembourg. Bilateral tax treaties between France and Luxembourg provide mechanisms to avoid double taxation.
