Hi, I run an internet based business selling products across europe. We are thinking of moving to France and would like to continue running the business from there. Would we need to register the business there or can we keep it in the UK? What would the tax benefits be for each country? Also, if the business remained in the UK, would I be registered as employed in france or the UK? I would like to stay in France and join the system, but what would be the best way & most financially beneficial way of doing this? Any advice would be great!! Thanks
