IRS: Helio owes $2.3M

The IRS says Brazilian race car driver and "Dancing With The Stars" winner Helio Castroneves owes $2.3 million in taxes.

That testimony came Friday from IRS agent Joann Levitt in Miami federal court. Levitt says the total comes from unreported income and improper deductions from 1999 to 2004.

Castroneves, his business manager-sister and a Michigan lawyer are charged with tax evasion and conspiracy. Levitt is the final prosecution witness after nearly four weeks of testimony. Next it will be up to the defense to put on a case for the two-time Indianapolis 500 winner and his co-defendants.

The defendants deny wrongdoing. Castroneves has said he relied on professionals to handle his finances.
