You left out Ireland with it's 17% Corporation Tax rate. We work very closely with some large multinationals that use Ireland to host their treasury. It's certainly somewhere I'd consider later in life. If you're in the UK it's a fairly short flight over, everything's in English and it's good for the craic too.
Yes, forgot about Ireland. That's also a good pick but I'm not sure how long they are going to keep that low tax rate given the rumors of their economical instability. Last I looked their corporate tax rate was about 12%.
