15. Boris Becker
Boris Becker is christened as Boom-Boom due to his extraordinary serve. Although, he has impressed both women and men alike with his tennis talent, he was not able to impress the tax authority of Germany. The ‘90s tennis star paid almost $3 million in interest and back taxes on his income from endorsements, appearance fees, and prize money. He claimed to be staying in Monaco, the tax haven, from 1991 to 1993, but he was actually living at his home in Munich with his kids and wife.
