Inland Revenue Department - Annual Report 2012-13

Information Technology

The Department has been making extensive use of information technology in daily operations and services.


The Department has a comprehensive and integrated IT infrastructure, including different types of computer application systems and platforms. Assessment processes are automated by the “Assess-First-Audit-Later” system. Tax audit and investigation works are facilitated by the use of data mining and advanced analytical tools. With extensive utilization of the Document Management System and Workflow Management System, the management, control and monitoring of documents, files and workflows are strengthened. Meanwhile, the Department’s network connects the computer system and staff workstations on different floors. Apart from adopting computerized workflow to enhance efficiency, a wide range of information is stored in the Department’s Intranet and General Enquiry Knowledge Database for convenient access by our staff at work. Moreover, e-mail and Internet facilities provide an efficient and environment-friendly communication platform for our staff.

We are actively implementing a large scale system infrastructure enhancement project. In 2012-13, we completed the upgrade of the system server and workstation infrastructure under Stage I of the project, commenced the activities on upgrade of Document Management System under Stage II, and also carried out the procurement activities for migration of mainframe applications under Stage III.
