Frequently asked questions

Which GST returns do I have to file?

It depends on your registration. A regular taxpayer files GSTR-1 and GSTR-3B (monthly, or quarterly under QRMP if turnover is up to Rs. 5 crore) plus the annual GSTR-9. A composition taxpayer files CMP-08 quarterly and GSTR-4 annually. Special registrants file GSTR-5, 5A, 6, 7 or 8. Use the tool above for your exact list and dates.

What is the QRMP scheme?

Quarterly Return Monthly Payment. If your turnover is up to Rs. 5 crore you can file GSTR-1 and GSTR-3B quarterly while paying tax every month through form PMT-06 by the 25th. Quarterly GSTR-3B is due on the 22nd (Group X states) or the 24th (Group Y states) of the month after the quarter.

When is GSTR-3B due?

Monthly filers: the 20th of the following month. QRMP filers: the 22nd or the 24th of the month after the quarter, depending on your state group. GSTR-3B for a period cannot be filed until GSTR-1 for the same period is filed.

Is the annual return GSTR-9 mandatory?

GSTR-9 is optional if your aggregate turnover is up to Rs. 2 crore and mandatory above that. GSTR-9C, a self-certified reconciliation statement, is required only where turnover exceeds Rs. 5 crore. Both are due by 31 December of the next financial year.

What returns does a composition dealer file?

Only CMP-08 (a quarterly tax statement, due the 18th of the month after the quarter) and GSTR-4 (the annual return, due 30 June of the next financial year). A composition taxpayer does not file monthly GSTR-1 or GSTR-3B.

What is the GSTR-1 due date?

Monthly GSTR-1 is due on the 11th of the following month. Under QRMP, quarterly GSTR-1 is due on the 13th of the month after the quarter, with an optional Invoice Furnishing Facility (IFF) by the 13th for the first two months of the quarter.
