On my case I don't know (I'm French), I currently work in the UK but I will definitely found a small company in a few years time with some online services, that's something I always wanted to do. Will I do it in France or in the UK ? The thing is, at least in the UK, if I buy a book, I can understand how the system works, in France I'm not sure even with the help of my parents I would be able to... It's just not only about taxes, I don't want to spend all my time filling some massive amount of paperwork nonsense. I still hope it's going to improve in the future but it seems it's just worse every year... :(
