Grammy-winning singer Lauryn Hill is facing charges for failing to file income tax returns on more than $1.6 million with the Internal Revenue Service, the U.S. attorney’s office in New Jersey said Thursday. Hill, 37, who lives in a suburb of Newark, did not file taxes on royalties earned during 2005, 2006 and 2007.

She is scheduled to appear before a federal magistrate on June 29, according to The Chicago Sun-Times. She could face a maximum penalty of a year in prison and a $100,000 fine on each charge.

Hill's 1998 album, The Miseducation of Lauryn Hill, earned Hill five Grammy Awards, including the Album of the Year and Best New Artist. It has sold well over eight million copies.

Hill has not appeared in the public eye in recent years, largely due to the fact that she is raising her six children, five of whom she had with Rohan Marley, the son of famed reggae singer Bob Marley. Hill's youngest son, Micah, was fathered by another man and will turn one year old next month.
