The Non-Filing Monitoring System (NMS) is a system developed by the Income Tax Department to identify individuals who are required to file taxes but have not done so.

E-Filing Portal: The Compliance Portal, administered by the Income Tax Department, serves as a specialized platform catering to various functions related to e-Verification, compliance issues, and capturing responses.

The Income Tax Department (ITD) employs a notice system via the compliance portal to address non-filing of Income Tax Returns (ITRs) by identified individuals.

Taxpayers now have the convenience of accessing their response history through the compliance portal. This feature allows them to track and review all responses related to specific e-Verification issues under the Related Information section
