Castro, 40, of Mansfield, Texas, was indicted on 33 counts of aiding and assisting in the preparation and presentation of a false and fraudulent return, U.S. Attorney for the Northern District of Texas Leigha Simonton announced on Wednesday. Court records show the indictment was filed under seal on Jan. 3.
Prosecutors say Castro carried out a pattern of falsely creating and submitting tax returns on behalf of dozens of unsuspecting taxpayers through his tax prep business, resulting in hundreds of thousands of improperly paid claims. He was arrested Tuesday and released later that day after making his initial appearance before U.S. Magistrate Judge Hal R. Ray, Jr.
