A cross-border consultant sets up a SARL-S
Published on 10 October 2026 · Updated on 10 October 2026
In short
A cross-border consultant SARL-S in Luxembourg starts with the business licence, which comes before RCS registration. A consultant living in France first finds a shared office, files the licence application on MyGuichet.lu, then signs the articles, pays in the €5,000 capital and registers with the RCS and RBE. This typical path is an illustration, not a promise of timing.
Typical scenario
Journey built from current rules, with no real client data. Aid amounts are official caps, not a guaranteed result.

Points to watch
- Social security: a cross-border worker who keeps an activity in their country of residence falls under the European coordination rules; check this before starting.
- First creation: the grant requires no salary during the period; it is applied for within 6 months of the licence.
- Timeline: for a SARL-S, the licence comes before registration; the office must therefore be found first.
