Hip-hop star Lauryn Hill has been charged with willfully failing to file income tax returns in the US.
Authorities say the singer earned more than $1.6 million (£1.03m) during the three years that she failed to file returns.
US prosecutors said her main source of income during the period 2005 – 2007 was royalties from her music and films.
Hill, who has not yet commented on the charges, is scheduled to appear in court on 29 June.
According to court papers, the 37-year-old owns and operates four corporations – Creations Music, Boogie Tours, LH Productions 2001, and Studio 22.
Hill was the only female member of rap group The Fugees, whose album The Score achieved worldwide success in 1996.
Two years later, she released her debut solo album – The Miseducation Of Lauryn Hill – to wide critical acclaim. It remains her only studio album to date.
The singer also appeared alongside Whoopi Goldberg in Sister Act 2: Back in the Habit.
She has six children and now rarely makes public appearances.
