Having testified in US Tax Court, given depositions for Department of Justice cases, led a litigation team of expert witnesses specialists at the IRS, and now in the private sector having reviewed and critiqued scores of expert witness reports for federal tax litigation, Mike offers several insights regarding tax litigation and the IRS.

Specific examples help clarify some of the “do’s” and “don’ts” in these venues.
