It is tax day and Dallas Mavericks minority owner Mark Cuban says he is ready to pay up. “This country has done so much for me, I’m proud to pay my taxes every single year,” Cuban said in a post on social media. Cuban originally said he would be paying $288 million in taxes, but corrected the number on Monday after hearing from KPMG. The response came in the middle of an online argument over corporate tax cuts. Cuban went on to say Monday that after “military service, paying your taxes is the most patriotic thing we can do.” Cuban sold his majority stake in the Dallas Mavericks to the Adelson family for $3.5 billion late last year.
