This discussion explores the possibility of issuing a GST credit note for the financial year 2019-20. While the general deadline for issuing credit notes is typically linked to the earlier of the September return filing or the annual return filing for that financial year, there's a possibility of issuing them later if compliance due dates have been extended. The consensus suggests that credit notes can generally be issued at any time, but it's crucial to be aware of the specific deadlines to ensure compliance.
I think GST compliance due date extended by the government, than according to the due date you can issue a credit note of F.Y. 2019-20 . if I am wrong please rectify
