Former teen idol Aaron Carter reportedly owes the Internal Revenue Service more than $1 million in back taxes.

Carter, the younger brother of Backstreet Boys singer Nick Carter, reportedly owes over $963,000 on his 2003 income, according to the New York Post. He also owes $45,350.11 on his 2006 income taxes.

The 21-year-old pop singer was a contestant on Dancing with the Stars, like race car driver Helio Castroneves, who also ran afoul of the IRS but was later acquitted of tax charges.

Aaron Carter, like his older brother, had a successful recording career as a teenager. He also starred in the E! reality TV series, “House of Carter,” with his four siblings. He has acted on Broadway in “Seussical the Musical” and appeared in movies such as “Fat Albert” and TV series including “Lizzie McGuire” and “Sabrina, the Teenage Witch.”

His manager, Johnny Wright, told Entertainment Tonight, "It is unfortunate that while Aaron was a minor, his finances were grossly mismanaged by his previous team which has led to the current situation of which he was unaware of until today. Aaron is working with a new team to take appropriate actions towards speedy resolution of the matter and looks forward to putting this behind him and moving forward with the next stage of his music career."

Carter’s parents filed a lawsuit against former manager Lou Pearlman alleging that he failed to pay hundreds of thousands of dollars in royalties on Carter’s 1998 album. Pearlman, who discovered a number of boy bands, including the Backstreet Boys and *NSYNC, was declared in contempt of court in 2003 for ignoring a court order to produce documents related to the royalty payments. He is currently in federal prison serving a 25-year sentence related to a $300 million Ponzi scheme, after pleading guilty in 2008 to charges of conspiracy, money laundering and making false statements during a bankruptcy case.
