I am a huge football fan (San Diego Super Chargers!), and I've known from quite some time now that the licensed NFL does not pay ANY taxes. While individual teams do, they are heavily diminished, but the organization that runs it all pays none because it is classified as a nonprofit - an exception written into us US tax law.
26 USC 501(c)(6)
Business leagues, chambers of commerce, real-estate boards, boards of trade, or professional football leagues (whether or not administering a pension fund for football players), not organized for profit and no part of the net earnings of which inures to the benefit of any private shareholder or individual.
Thoughts? I find this rather laughable. Read more about it here: Why Does the National Football League Deserve Tax-Exempt Status?*|*Sports Fans Coalition
