Amendment to Filing Deadlines: revised due dates for specified 3B return actions and electronic credit ledger compliance. The amendment substitutes earlier August 2017 dates in multiple table entries with new dates (twenty-fifth and twenty-sixth August, 2017) and inserts the phrase 'on or before 25th August, 2017' after the reference to the electronic credit ledger; the notification takes effect from 20th August, 2017.
