O.J. Simpson, taxes. Two things that seemingly do not go hand in hand. We're not sure who the footballer-turned-criminal's accountant is, but they need sacking immediately. He may still be behind bars, but Simpson appears to think that he can stop paying his taxes. Subsequently, the IRS has slapped another lien on him.

According to TMZ.com, a federal lien filed in December stated Simpson failed to cough up $17,015,99 for the year 2011. Uncle Sam has previously filed a lien for $179,435,07 for the years 2007-2010 and the State of California say O.J still owes $318,566,04 for the year 2000. All this means his tax debt total is an incredible $515,017,10!  It's probably worth remembering that he still owes around $33.5 million to the families of Nicole Brown Simpson and Ronald Goldman too. He was acquitted of their 1994 murders after a lengthy and hugely publicized criminal trial, however, a civil court awarded a judgement against O.J. in 1997. He has paid little of the huge financial penalty incurred for their wrongful deaths.

In September 2007, Simpson was arrested in Las Vegas, Nevada and charged with felonies including armed robbery and kidnapping. He was found guilty and sentenced to thirty-three years imprisonment with a minimum of nine years without parole.
