The Cayman Islands
The tropical Cayman Islands are not an independent country but rather a crumb leftover from the feast that was once the British Empire. But the 56,000 inhabitants live in one of the top ten richest countries per capita — the average annual income in 2010 was $47,000. The Caymans have made a name for themselves as tax havens for multi-national businesses. Currently, the Cayman Islands impose no income, inheritance, or corporate taxes. Therefore, if companies can prove that their investments are sourcing income from banks in the Caymans, then that income is only subject to Cayman taxation rates — i.e. none, making the territory a favorite of high rollers in more ways than one.
