Los Angeles - Lauryn Hill has been charged with failing to file tax returns for three years.
The 37-year-old singer - who has not released a solo album in 10 years - has been accused by a Federal Court in New Jersey of not filing the returns in 2005, 2006 and 2007 despite earning $1.6m in that time.
Lauryn was charged on Thursday and could face up to one year in prison for each count and $300 000 in fines.
According to TMZ.com, Lauryn is due to appear in court on 29 June.
Just last year Lauryn found herself in a legal wrangle after her former fashion consultant accused her of stealing clothes.
Company Via Davia Vintage claimed the former Fugees star took the majority of a "wardrobe of high fashion items" from them after they agreed to provide them for her 2007 tour of Europe.
She was also sued in relation to the tour for harassment and unpaid wages by Jay Gore, a guitarist in her band, who claimed she would insult the band while he toured with her.
Part of the lawsuit stated: "After shows, Hill would demand that the musicians and road support personnel attend meetings where she would engage in a person-by-person critique and berating."
