I am set up as an ME and working through your helpful blog i am trying to create an account online at 'impots'. I cant seem to find the Numéro fiscal, Numéro de déclarant en ligne and Revenu fiscal de référence details they are asking for. I also dont seem to have had the 'memento fiscal' you mention although I have had a return to complete for CFE which I sent back in mid December. Do I need to wait until I get something further?
Many thanks for your help.
