I just had a thought about this splitting it equally amongst themselves once they get out... won't that be deemed a gift, for those that get the lower amounts and need the others to give money to them to make it up to 10k, and therefore won't it be taxable?
the prize money they get officially off BB is tax free isn't it but a share out between themselves after it is finished wouldn't be surely?
They'd have to work it so they cover any tax payable and still all get the same amount if that is what they decided to do with it.. so slightly less than 10k each?
Blimey my head hurts after that
