Prior to working on any Whistleblower Claim, the IRS will conduct what is known as a “taint review.”  This review ensures good behavior by our government, and that in this case, it will ensure that the IRS is not encouraging Whistleblowers to provide information/documentation that would not otherwise be available to the IRS.  In fact, there is the possibility that the Court itself would throw out information/documents that should not have been available to the IRS or perhaps, even worse, throw out the entire action (i.e. audit) by the IRS if it is using tainted information from a whistleblower.
