Thanks for that. I understand your first 2 paras but if Channel Isles and IOM are max 20% income tax, what means please "they don't come cheap" do you mean houses are expensive or indirect taxation is expensive or general cost of living et al?
Right, in most of these tax havens, CI and IOM for example, there are two property tiers. One for those with residential qualifications, locals, and a second much higher one for incomers who often have to prove their wealth before they can even enter the market. Furthermore the cost of living tends to be higher merely because of the logistic complications of re-supply. I did a study once of the cost of living viz a viz Scotland and England and Scotland came out 13% more expensive than England. If one took in the Western Isles one could add another 13% on to the Scottish prevailing prices and frequently the choice was somewhat limited. I recall commenting that meat prices reflected the only butcher's monopolistic opportunities!
The CI do not levy VAT, the IOM does and at a lower threshold level to boot.
