Extension of GST compliance deadlines: state notification postpones certain filing cut offs and adjusts proviso timelines. Amendment substitutes earlier May cut off dates in the first paragraph of the prior notification with later June dates and, in one proviso, replaces a mid June cut off with a mid July date, thereby extending the due dates for specified GST compliances; the amendment is effective retrospectively from the thirtieth day of May, 2021 and otherwise leaves the prior notification's terms intact except as amended.
