Online registration requirement for budgetary support under GST mandates electronic claim filing and processing with portal-issued unique IDs. Online registration and electronic filing are mandated for units seeking budgetary support under the GST regime in specified states; eligible units must obtain one-time registration on the ACES-GST portal to receive a unique ID used for submission, processing, sanction and payment of claims. Jurisdictional Deputy Commissioners or Assistant Commissioners of Central Tax will process and approve registrations and online claims; manual filing is discontinued and previously manually registered units must re-register online without additional verification based on earlier approval.
