IT grievance redressal mechanism enabling committee-approved remediation and penalty waiver recommendations for taxpayers affected by portal glitches. An IT-Grievance Redressal Committee mechanism addresses portal-wide GST filing failures by having GSTN and appointed nodal officers collect evidence of bonafide filing attempts, identify affected taxpayers, and submit proposed technical and procedural solutions to the Committee. The Committee examines and approves remedies, directs implementation to GSTN and field formations, and may recommend waiver of fines or penalties in mitigating circumstances; GSTN communicates directly with affected taxpayers and reports implementation outcomes.
