Every registered dealer is required to file the GSTR-1 return for each month/quarter as applicable. The return contains details of all outward supplies made during that particular tax period.

The due date for GSTR-1 is usually 11th of the succeeding month. For quarterly filers, the due date is the 13th of the month following the quarter.
