Automation of refund processing: electronic filing, deficiency tracking, and electronic disbursal replacing manual refund workflows. Automation requires applicants to file refund claims and supporting documents via the ICEGATE Portal, enables re assessment requests and pre filled forms, and mandates generation of a unique application reference on filing. Proper officers must intimate deficiencies within a short period, issue acknowledgements when defects are cured, and communicate show cause notices or speaking orders electronically, including examination of unjust enrichment. Sanctioned refunds will be paid electronically to registered bank accounts via the PFMS, while credits to the Consumer Welfare Fund continue as before; audit will shift from compulsory pre audit to post audit with selection criteria to be finalised by audit authorities.
