E payment of GST: GSTN portal issues CPINs and coordinates bank CIN/BRN confirmations for automated reconciliation. E-payment of GST will operate through a GSTN pass through portal that generates electronic challans with a 14 digit CPIN, supports internet banking and card payments via authorized bank gateways, and receives real time payment confirmations (CIN and BRN) from e FPBs. GSTN forwards CPINs and consolidated transaction files to accounting authorities; RBI's e Kuber issues digitally signed e scrolls and credits major head government accounts. e FPBs, e PAOs/e Treasuries and CAS perform daily and monthly reconciliation using standardized data elements and taxpayer master updates to map payments to jurisdictional ledgers.
