Lauryn Hill Also Faces State Tax Trouble

A civil judgment was entered against Hill on June 14th by a Jersey court -- finding the Fugees singer is responsible for $446,386 in unpaid state taxes.

A week before the judgment came down, Hill was charged with failing to file FEDERAL tax returns in 2005, 2006, and 2007 ... a federal crime. She pled "guilty" and now faces 3 years in prison.

But lucky for Hill, the state tax situation hasn't become a criminal matter ... yet.
