I just found a text who says that you don't have to declare anything in France if you already pay your income tax abroad ,corresponding to at least 2/3 of what you would have payed in France. Then there is another exemption if you stay less than 180 days in France, which should be the case with Virgin.The problem starts when you earn revenue in France, even if it's negligeable: in this case you have to declare your British earnings in France. Anyway, every time you call the tax service, you get a different answer. The only solution if you want an official answer is to write them.But then, once you've established contact, you triggered their interest.
Here's the adress in Paris if you want
Impôts (Non-Résidents - DRESG)
cellule de renseignements
9 r Uzès 75002 PARIS
By the way, do you have a good tax advisor in the UK? I'm starting with Virgin in 10 days
