You will need to be a residen tof that country in order not to be taxed. People go and live in a virtually tax free country such as dubai.They still work in this country though. Its normally rich bankers and wealthy people who have offshore bank accounts.
I invest my money in stocks and shares.I make nice sizeble returns aswell. 5% every two months tax free as it's oli shares. They are hard to get into now as oil prices have gone up and up, so shares are abouty £1.90 each.All tax free as they can't tax shares.
How much money do you want to put away anyway?
