Michael Jackson's ex-manager Raymone Bain pleaded guilty Wednesday to charges that she did not pay federal or D.C. income taxes.

Bain was charged with two counts of failure to file federal and D.C. income tax returns, which amounts to some $200,000 to $400,000 in taxes from 2006-2008, according to the U.S. Justice Department.

She could face up to 12 months in prison and be fined $100,000 for the federal offense, and up to six months in prison and fined $5,000 for failing to file district taxes.

The former manager, who started representing Jackson since 2006, eventually went on to become president of Michael Jackson Co. and manage his daily operations. She reportedly earned a substantial income.

Bain will be sentenced on August 31 by U.S. District Judge Alan Kay.
