Frequently asked questions

When is GSTR-3B due?

The 20th of the next month for monthly filers. QRMP filers file quarterly on the 22nd (Chhattisgarh, MP, Gujarat, Maharashtra, Karnataka, Goa, Kerala, Tamil Nadu, Telangana, Andhra Pradesh, DNH & DD, Puducherry, A&N, Lakshadweep) or the 24th (all other states and UTs).

When is GSTR-1 due?

The 11th of the next month for monthly filers, and the 13th after the quarter for QRMP filers. QRMP filers can upload B2B invoices through IFF by the 13th for the first two months of the quarter.

What if a due date is a Sunday or holiday?

The due date does not move by itself. Extensions come only through a government notification; we update the calendar when one is issued.

What is the late fee if I miss it?

₹50 a day for GSTR-3B and GSTR-1 (₹20 for nil returns), capped by turnover, plus 18% a year interest on tax paid late in cash. Use the GST late fee calculator to work it out.
