Five-time Grammy winner Lauryn Hill has been charged with failing to file income tax returns for several years with the IRS, the U.S. Attorney’s office in New Jersey announced Thursday.

Hill earned more than $1.6 million during 2005, 2006 and 2007, the three years that she allegedly failed to file returns, federal prosecutors said. Hill’s primary source of income is royalties from the recording and film industries, prosecutors said. She also owns and operates four corporations: Creations Music, Inc., Boogie Tours, Inc., L.H. Productions 2001, Inc. and Studio 22, Inc., according to court papers.

Hill is due to appear on the charges on June 29.

The multi-talented Hill made headlines earlier this week when she stepped into a feud involving Nicki Minaj and Hot 97 DJ Peter Rosenberg. Hill used Twitter to support Minaj's decision to cancel her Sunday performance at Hot 97's Summer Jam concert in New Jersey because she felt disrespected.

"We have to find a better way to commercially exploit music, while giving artists their proper respect," Hill tweeted.
