Department of Revenue Investigation (DRI) was established in 1994. Prior to this, a separate division called Revenue Investigation Division (RID) was established  in the Ministry of Finance to take care of revenue leakage investigation and controlling economic crimes. In 1994, the RID was converted into DRI to handle the ever extending functions related to investigation of revenue leakages and controlling economic crimes. Currently, this Department is located at Hariharbhawan, Lalitpur, Nepal.

At present, the DRI has four regional unit offices located at different Development Regions of the country. Itahari Unit Office (Eastern Region), Pathalaiya Unit Office (Central Region), Butwal Unit Office (Western Region) and Kohalpur Unit Office (Mid and Farwestern Region) cover the respective regions in taking care of the given responsibilities.
