Mixed feelings about Andorra, it doesn't sound too bad to live in but the memories I have of it are that of a huge supermarket where herds of french and spanish folks go to buy cheap alcohol and tobacco, plus it is more difficult to organize at short notice, english speaking school and immigration wise.
Besides living in Spain while enjoying Gibraltar taxes seems to have grown harder, i suspect it's a no go for someone with children of school age.
I sent an email to 2 law offices in Gib, will report here if they reply.
Curious to read about any trader living in Jersey, i went through the residency information and it does look as easy as hoping on a boat with one's luggage from the French coast, register at the official department to get a ssn (although one has to pay in full for all their medical needs for at least 6 months), tax number and soon a public school for kids, in case it's too late to get space in the private schools. Gibraltar is similar if one doesn't go the Cat 2 route. Our next move will depend on Mrs as well, probably won't be sure of it until I do land in one of those places along kids and suitcases.
I'm wondering about the "unlikely" bit in Jersey tax department website. Will one get taxed if they make significant coin ?
