Former Heisman trophy winner O.J. Simpson is in jail but still cannot escape his growing financial woes, as it was recently revealed that he owns the IRS a large sum of money. 

Simpson was hit with three huge tax liens over the last 12 months, according TMZ. The most recent lien was filed in December when Simpson did not pay $17,015.99 due for his 2011 taxes.

The IRS also filed liens for $179, 435.07 to cover the years 2007-2010. On top of those huge debts, Simpson still owes the state of California $318,566.04 for the year 2000. This brings Simpson grand total tax debt to $515,017.10.

In 2008, the 65-year-old former NFL player was sentenced to 33 years in prison for a botched armed robbery in a hotel room. On Sept. 13, 2007, Simpson and five other men were caught as they attempted to retrieve his own sports memorabilia and mementos from two dealers in a Las Vegas hotel room. Simpson claimed the items, including a diamond ring belonging to his wife, were stolen from him.

It was Simpson’s choice to bring a gun into the hotel room that landed him in prison for armed robbery. The judge at the trial said that someone could have been shot in the violent confrontation. The evidence of the crime was all recorded on video tape.

Simpson was acquitted in 1995 for the murder of his ex-wife Nicole Brown Simpson and her friend, Ron Goldman. Later, O.J. was held liable for their deaths in a civil suit filed by both Brown and Goldman's families, and hit with a $33.5 million settlement.

Simpson is currently serving out his 33-year sentence at the Lovelock Correctional Center in Nevada. He will be eligible for parole in 2017.
