Extension of time limit for filing GSTR-3B: amended notification postpones deadlines and fixes electronic credit ledger deadline. The notification amends a prior Karnataka SGST notification to substitute later filing dates for specified table items and inserts a requirement that entries into the electronic credit ledger be made on or before the newly prescribed date; the amendments are issued under the Rule-making powers of the Karnataka GST Rules and Act and take effect from 22nd August 2017.
