Boxing legend Floyd Mayweather Jr. is facing a $3.4 million IRS bill for unpaid taxes from 2009, The Detroit News reported late Friday.

The latest IRS penalty for back taxes comes three years after Mayweather agreed to pay the IRS $5.6 million in unpaid taxes from 2007.

The undefeated Mayweather, who earns millions of dollars per fight, has recently been bragging about the massive cash he has won from betting on NBA games.

"Today was a good day. It took 24 minutes to make $40,000 dollars on the Portland Trailblazers," he tweeted at the end of March.

Earlier in February he also bragged about the thousands of dollars he won from a Dallas Mavericks game and later from a Detroit Pistons win.

The boxer's tax dispute comes amid a series of courtroom fights ahead of him in April.

Mayweather faces an April 25 trial date on a battery charge over an altercation with a security guard for his homeowners association, who claimed Mayweather poked him during a November argument regarding cars parking outside Mayweather's home.

The 34-year-old also faces a court hearing on April 28 on domestic violence charges that could send the fighter to prison for up to 34 years if convicted on all charges, which include felony counts of grand larceny, coercion and robbery.

Mayweather is accused of striking and threatening his former girlfriend, Josie Harris, stealing her mobile phone and threatening two of their children in an incident last September.

Meanwhile, Mayweather was dealt a blow in March when a federal judge refused to dismiss a defamation lawsuit against him, filed in 2009 by Filipino boxing star Manny Pacquiao.

Pacquiao alleged in his lawsuit that "Mayweather and others set out on a course designed to destroy Pacquiao's career, reputation, honor and legacy and jeopardize his ability to earn the highest levels of compensation."

Pacquiao had never tested positive for performance-enhancing drugs but in his 2009 lawsuit claimed that Mayweather, his father, uncle, promoter Oscar de la Hoya and his employee, Richard Schaefer, conducted a campaign in a set of interviews to make people think he had used them.
