The information gathered by CIB is segregated automatically by the computer system and disseminated to concerned Income-tax Officers (ITOs), who do assessment work or to the investigation wing of the Department, which conducts searches. The Directorate of Systems of the Income-tax (I-T) Department in New Delhi handles the overall computer network system.
