Pay outstanding dues to ₹0
IDBI won't accept a closure request while there's any outstanding balance — including pending EMI conversions, recently-converted purchases, or annual fee charges that haven't yet appeared on a statement. Confirm balance via IDBI's mobile app or call customer care. If you have a refund pending from a merchant, wait for it to credit before closing — refunds after closure get bounced back to the merchant, not you.
