Embattled boxer Floyd Mayweather, Jr. is allegedly facing a massive $3.4 million tax bill, according to a U.S. report.
Mayweather Jr. is said to owe income taxes from 2009 - the same year he came out of retirement to fight Juan Manuel Marquez in a reported $25 million deal.
Officials at America's Internal Revenue Service (IRS) filed a lien against Mayweather Jr. in Clark County, Nevada on 21 January, according to The Detroit News.
The lien was filed just weeks after the star was arrested on suspicion of beating his ex-girlfriend and stealing her cell phone during an argument in front of their three children.
Mayweather Jr. is facing a number of charges stemming from the alleged incident back in September, including felony coercion, grand larceny and robbery, as well as misdemeanour domestic battery and harassment.
He also faces a criminal battery charge stemming from an alleged altercation with a security guard outside his Las Vegas home in November.
He is due back in court in Las Vegas on 25 April.
