My girlfriend is considering becoming a home hair stylist in France. I see that there are lots of businesses located in peoples homes for health and beauty in France. Can we change our apartment address to a working address for this service? How would this affect things like tax fonciere or tax d’habitation, and what other considerations / costs would need to be thought of for this? There is already one auto-entrepreneur registered at the address, we may consider buying another apartment for this.
