GSTR-3B is a monthly self-declaration that has to be filed a registered dealer from July 2017 till March 2018.


1. Basics of GSTR-3B

A. What is GSTR-3B?

GSTR-3B is a simple return form introduced by the CBEC for July 2017 to March 2018.

GSTR-3B contains details of outward and inward supplies. Do note that you do not have to provide invoice level information in this form. Only total values for each field have to be provided.

You must file a separate GSTR-3B for each GSTIN you have.

The tax liability of GSTR-3B must be paid by the last date of filing GSTR-3B for that month.

B. When is GSTR-3B Due?

GSTR-3B has to be filed by 20th of next month till March 2018.

For example, the due date of the return for the period December 2017 is 20th January 2018.

C. Who Should File GSTR-3B?

Every person who has registered for GST must file the return GSTR-3B. This return form must be filed and submitted by you even if you do not have any transactions during these months.

However, the following registrants do not have to file GSTR-3B

D. Revising GSTR-3B

GSTR-3B cannot be revised. There is no way of revising GSTR-3B once it is filed.

E. Late Fee & Penalty

Filing GSTR-3B is mandatory. Even if a taxpayer has no transactions during a month, it will still have to file a nil return.

Interest @ 18% per annum is payable. It has to be calculated by the taxpayer on the amount of outstanding tax to be paid. The time period will be from the next day of due date for filing to the date of payment.

Late Fee for filing GSTR-3B after the due date is as follows:

  • Rs. 50 per day of delay
  • Rs. 20 per day of delay for taxpayers having Nil tax liability for the month.

Note: Late fee for July, August, and September has been waived. Any late fees paid will be credited back to Electronic Cash Ledger under ‘Tax’ and can be utilized to make GST payments  (as per the 23rd GST Council meeting).
