Quick Answer
Criminal tax administrative investigation has four stages: (1) CI special agent assignment and preliminary investigation; (2) subject interviews and document gathering; (3) Special Agent’s Report (SAR) recommending prosecution; and (4) Tax Division review and U.S. Attorney’s Office decision. The short version is that the administrative phase precedes indictment. In our experience, engagement with counsel during administrative phase can often prevent prosecution — once referred to USAO, options narrow.1
