One of the enduring tax mysteries is the 26-year battle between the Church of Scientology and the IRS culminating in a 1993 settlement (during Fred Goldberg's stint as Commissioner) in which the IRS agreed to grant tax exempt status to the church, which in turn agreed to drop its multi-front litigation "war" against the IRS. Yesterday's St. Petersburg Times began a three-part special report on the church, with Part 1 including details of the Scientology-IRS settlement.
