According to a federal lien filed in December, O.J. failed to cough up $17,015.99 in taxes for the year 2011. This makes for the THIRD lien filed against him in the last 12 months.
As TMZ first reported, Uncle Sam filed a lien for $179,435.07 for the years 2007-2010 and the State of California says he still owes $318,566.04 for the year 2000. Tax debt total = $515,017.10.
And don't forget ... he still owes MILLIONS to the families of Nicole Brown Simpson and Ronald Goldman for that whole double murder thing.
Better keep pounding those license plates.
