Cowell made perhaps the biggest decision of his life this year when he ended his Idol run in favor of producing his own talent show, The X Factor, in America. Cowell, who also produces America’s Got Talent, says The X Factor format is his favorite. It won’t compete against Idol. Upon his appearance on Top Gear, it was revealed that Cowell pays more than £21.7m per year in income tax, suggesting that his taxable income is over £54.25m per year with income tax at the time approximately 40%. Cowell has a $22 million, 11,550 sq ft (1,073 m2) home in Beverly Hills.
