Can anyone tell me the Swiss tax situation with respect to premium bonds held in the UK? Presumably, they are subject to wealth tax, but what about any winnings. Are these treated as income, or (since they are free of tax in the UK) is this not the case?
Haven't asked at the Swiss tax office (and won't) but I cannot see how prize money becomes taxable. It isn't income in the sense of a guaranteed rate of return. Certainly in UK it is not decalarable as income, so in the eyes of the 'giver' it isn't income, just prize money.
