Floyd “Money” Mayweather Jr., a boxer with an undefeated professional record of 41 wins and 0 losses, was recently handed a loss by the IRS of approximately $3.4 million in back taxes from the 2009 tax year.

In 2009, Mayweather came out of a 21-month retirement to defeat Juan Manuel Márquez in twelve rounds. Can’t say I’m surprised the decision was unanimous considering Marquez only managed to land 70 of his total 583 punches while Mayweather landed 289 of his 490 total punches (courtesy of Wikipedia). Mayweather reportedly earned $25 million from the fight, and presumably failed to properly give Uncle Sam his share.

This isn’t the boxing legend’s first losing bout with the IRS. In late 2008, the IRS filed a tax lien to the tune of $6.2 million against Mayweather. I find it interesting that the article suggested the lien could push Mayweather back into the ring, because shortly thereafter, the Márquez fight arrangements commenced. Only time will tell whether Mayweather’s most recent tax troubles force “Money” to continue on this vicious cycle. It’s pretty clear the man has serious financial management issues.
