Grievance redressal framework: designate dedicated grievance officers and standardized acknowledgement and coordination procedures for taxpayer complaints. Establish a structured grievance redressal framework by appointing dedicated Grievance Officers at key Custom Houses, airport terminals and Collectorate headquarters with authority to call for papers, propose solutions and refer matters to Collectors; ensure recordkeeping and monitoring by Collectors and Zonal Principal Collectors. Complementary measures require filling Public Relation Officer posts with experienced officers or deputationed specialists, providing special pay, issuing a leaflet on complaint procedures, prompt acknowledgement of grievances with timelines, acknowledgement slips on forms, appellate office grievance coordinators, and combined interdepartmental committees for single-point redress.
