GST Filing Deadlines for FY 2026-27

Every GST return has a hard deadline, and missing one triggers late fees and interest that compound quietly. This guide lists the standard due dates for GSTR-1, GSTR-2B and GSTR-3B in the current financial year.

GSTR-3B is due monthly on the 20th, GSTR-1 on the 11th for monthly filers, and GSTR-2B is auto-populated by the 12th-14th. Quarterly filers follow the QRMP scheme calendar.

Arthvahi tracks these dates against your filing state and shows them on the returns page, so a period can never silently slip past its due date.
