Andorra >
Easy welcoming immigration laws, setup a company for 6k, get residency for 15k (given back when you leave). Takes 3 months
Income tax: 0% until 24k, 5% until 40k (0% if married), 10% above. But 0% is achievable through a holding company. No dividends or donation fees, no inheritance tax.
Zero crime, unemployment almost non-existent (worse now with Covid).
Administration tasks are kept to the minimum (4 years ago you wouldn’t even declare revenues, there was no accounting. Nowadays they trust what you declare without asking for backing documents)
Cost of living closer to Spain than France (minimum wage < 1000€)
Very laidback. Longest longevity in the world after Japan. Beat it !
Quite a bunch of traders and gurus operate from here
