His battle with the IRS
While Mayweather is the king of the ring, no one can beat the IRS. The man has been slapped with multiple tax liens over the years, but things got particularly testy in July 2017. According to Forbes, Mayweather owes the feds a pretty hefty tax bill — like $22.2 million from 2015.
That’s a pretty crazy number, especially for a guy who’s constantly posting photos on social media of all his cash. However, this revelation has shed a new light on his bout with Conor McGregor, leading many to believe that Mayweather accepted the fight with the Irish UFC star to pay off his debt. In fact, hoping to postpone paying his bill, Mayweather recently filed a petition with the U.S. Tax Court that said he had a “significant liquidity event scheduled in about 60 days from which he intends to pay the balance of the 2015 tax liability due and outstanding.”
So while Mayweather now has a perfect record of 50-0, it won’t save him from coughing up all that cash. No matter how skilled you are at the sweet science, the IRS is always going to walk away with the KO.
