GST interest on delayed GSTR-3B liabilities remains payable on...

GST interest on delayed GSTR-3B liabilities remains payable on the cash component until the Electronic Cash Ledger is debited, even where sufficient funds were deposited and continuously available earlier. A ledger credit evidences deposit with the Government but does not discharge an identified tax liability; debit is required for payment. The proviso excluding continuously available cash-ledger balances from interest computation operates prospectively and does not apply to earlier periods. A show-cause notice causes no defect where the taxpayer received the demand computation, responded fully, and suffered no prejudice. Failure to provide a requested personal hearing breached statutory requirements, but remand was unnecessary absent surviving substantive prejudice. Interest demands remain subject to reconciliation and credit without double recovery.
