Monaco, Monaco

With a population of just 38,423 and the world's highest nominal GDP per capita, Monaco is a tax haven for the ultra-wealthy, not a haven for the average person. Despite its picturesque setting on the French Riviera, the country's bureaucracy is a persistent headache, and even French citizens must still pay taxes to their home country. For those seeking a low-tax enclave and don't mind navigating the red tape, Monaco may be an alluring option, but it's hardly a realistic destination for the majority.
