Conor McGregor Says Floyd Mayweather Should Have Paid His Taxes, Stayed Retired

Ahead of their Aug. 26 fight, Conor McGregor used Floyd Mayweather Jr.'s tax situation as an opportunity to get a dig in on his opponent.

"That's gotta sting," McGregor said in an interview with TMZ Sports. "... He shoulda paid his taxes and stayed retired and kept my name out of his mouth" (Warning: Video contains NSFW language):

On Monday, ESPN.com's Darren Rovell shared a report from Law360's Bryan Koenig that stated Mayweather asked the federal government to wait before collecting the taxes he owes from 2015.

Rovell noted that failing to pay taxes on time generally results in a 0.5 percent penalty for every month the taxes are overdue. Mayweather would then owe the government 7.5 percent in addition to his overdue taxes, which Koenig didn't identify.

In the petition they filed on Mayweather's behalf, his representatives wrote the boxer has a "significant liquidity event scheduled in about 60 days" that will help him pay his outstanding tax bill, per Koenig, which is almost certainly Mayweather's bout with McGregor.

BoxingScene.com's Keith Idec reported Mayweather could make as much as $100 million for his fight purse, which wouldn't take into account his share of the fight's gate and pay-per-view revenues.

The Los Angeles Times' Lance Pugmire reported the pay-per-view fee for Mayweather vs. McGregor will be $99.95 for the high-definition broadcast and $89.95 for the standard broadcast.
