The IRS filed a tax lien on him on December 18 for past taxes he owes from 2008 and 2009, which total up to more than $4 million.
According to the document, Williams has two outstanding balances from 2008 and 2009, owing exactly $3,200,908.92 for the year 2008 and $829,352.11 for the year 2009.
Add them up and he's on the hook for over $4 million -- unfortunate timing given his recent announcement that he's retiring from stand-up comedy.
Williams was all over the place (and the news) in 2012, arrested for a fight in a Seattle bar and charged with various misdemeanors after leading police on a wild chase when they tried to apprehend him while he was driving a three-wheeled motorcycle outside his hotel.
He'd be caught on security film later that night slapping a Target employee, claiming later he was justified in doing so because the employee used the "N word" and disrespected poor Mr. Williams.
Williams was also charged with assault after hitting a man in the head with a bottle on his tour bus along with several other run-ins with fans and police that often resulted in fisticuffs.
In early December he seemed to have had enough, announcing his retirement: "I'm just gonna go ahead and announce my retirement from stand-up. I'm kinda done. I've discussed it with my kids, I wasn't gonna do in the middle of a Seattle street, I was going to go to Los Angeles and do it in the offices of ICM or LiveNation."
Williams hasn't exactly been on the straight and narrow in the past, either, with charges for possessing a stolen weapon in an airport and arrests for burglary on a lengthy rap sheet that just seems to get longer and longer.
