Having read through all the previous posts, i'm still uncertain how much applies to my situation which is: For the last 5 years a friend and i have run a small, office based UK Ltd Co that provides a service to its clients. I am now looking to move to France and run it from there, with my friend still handling their aspect from the UK. There are no other staff and we both fall under the standard tax bracket. Closing the UK Ltd Co is not an option for us. Can i set myself up in France as consultant under a micro bic and invoice the UK Co on a consultancy basis? (I will need to return to the UK for a day or two every couple of months for work reasons.) If so, how much allowance am i granted for expenses, as i understand it is the turnover less this figure that the cotisations are based on. How long can a micro bic trade for? (i read somewhere that after 2 years a micro bic had to be turned into a different type of company) If a micro bic is not appropriate for me, what is and approx what % cotisations can i expect to pay? I have spent hours looking at numerous sites trying to understand this, but all the micro bic info seems to apply to B&B's. Any advice on my situation would be hugely appreciated.
