The Internal Revenue Service (IRS) is effectively using data analytics to combat tax abuse domestically and around the world. Through the use of data, analytics, and highly trained personnel, the IRS is able to identify taxpayers who have a high potential for committing tax avoidance and abuse. An indication of the importance the IRS places on the use of data analytics to combat tax evasion and financial crimes is demonstrated by the establishment of the Nationally Coordinated Investigations Unit (NCIU) and other data analytics units such as Data Solutions and the Office of Research Applied Analytics and Statistics.
