"The Juice" is in trouble again.
Imprisoned former football standout O.J. Simpson failed to pay $17, 015.99 in taxes for 2011, according to a federal tax lien filed in December, TMZ reports.
That sum, combined with $179,435.07 for the years 2007-2010 and $318,566.04 the State of California intends to collect for state taxes, brings Simpson's unpaid tax grand total to $515,007.10.
Not to mention his other expenses.
"And don't forget ... he still owes MILLIONS to the families of Nicole Brown Simpson and Ronald Goldman for that whole double murder thing," TMZ points out.
Simpson is currently serving a 30-year prison sentence -- including nine years without parole -- in Nevada's Lovelock Correctional Center after a 2008 conviction involving armed robbery and kidnapping.
Simpson was found not guilty of murdering his ex-wife and her friend in a highly publicized criminal trial. A 1997 civil court judgement against Simpson ordered him to pay the families of those victims $33.5 million.
Correction: A previous version of this story stated that Simpson was serving his sentence in Las Vegas.
