The Chief Data and Analytics Officer, RAAS, should develop consolidated, written policies and procedures for developing the Tax Gap to help ensure repeatability, timeliness, quality, and continuity of the Tax Gap estimates and improve oversight.
Develop written policies and processes to formalize the internal and external reviews of the Tax Gap estimates.
