@AlainVagner I was trying to find out how to pay "Impôt commercial communal"
So, this https://guichet.public.lu/fr/entreprises/fiscalite/impots-benefices/benefices-patrimoine/impots-divers/impot-commercial-communal.html then lead to this https://impotsdirects.public.lu/fr/formulaires/pers_physiques.html
I ended up starting the wrong form, because, it's a mess. And now I have a wrong form in my guichet and haven't found how to abort it.
