GSTR-9 filing period extended to include April to October 2022; returns permitted until 30 November. The amendment to the GST rules revises FORM GSTR-9 instructions and table entries to replace references to April-September 2022 with April-October 2022 and to allow filing of those returns up to 30th November 2022, with the change made under the State's rulemaking power and effective from publication in the Gazette.
