A Complete Guide on GSTR – 3B

What is GST Return 3B?

GSTR – 3B is a self-declared summary return filed by every regular GST taxpayer. Unlike other returns, it is used to report the summary of your outward supplies (sales), inward supplies (liable to reverse charge), and the eligibility of Input Tax Credit (ITC).
It is a crucial return as it is where you finalize your tax liability for the period and pay the tax to the government after adjusting the available ITC.

It primarily gathers data from:
GSTR-1: (Details of outward supplies)
GSTR-2B: (Auto-generated ITC statement)

Who needs to fill GST R-3B?

All regular taxpayers registered under GST are required to file GSTR-3B for every tax period.

Persons REQUIRED to file GSTR-3B:

  • Normal Registered Taxpayers
  • Casual Taxable Persons
  • SEZ Units and SEZ Developers

Persons NOT REQUIRED to file GSTR-3B:

Last date to file

The due date for GSTR-3B is the 20th of the following month for monthly filers. For QRMP (quarterly) filers, the deadline is the 22nd or 24th of the month following the quarter, depending on your state. Filing after these dates attracts immediate late fees and interest.

Mistakes to avoid while filing GST R-3B

  • Mismatch with GSTR-1
  • Claiming Ineligible ITC
  • Ignoring GSTR-2B
  • Missing Reverse Charge (RCM) Liability
  • Incorrect Head Selection

Late Fee for delayed filing

The late fee for filing GSTR-3B after the due date is ₹50 per day (₹25 CGST + ₹25 SGST), which is reduced to ₹20 per day for Nil returns. This penalty is subject to a maximum cap based on your annual turnover. Additionally, 18% annual interest is charged on any net tax liability paid after the deadline.

Frequently Asked Questions

  1. Can I file GST R-3B without filing GST R-1?

    No. Sequential filing is now mandatory. You must file GST R-1 before the portal allows you to file GST R-3B for the same period.

  2. Can GSTR-3B be revised?

    No, GST R-3B cannot be revised. Any errors or omissions can only be rectified in the return of the subsequent tax period or through the annual return (GSTR-9).

  3. Can I file GSTR-3B without paying tax?

    Technically, no. The GST portal does not allow you to “Submit” or “File” the return unless the total tax liability is fully discharged through ITC or Cash Ledger.

  4. What happens if I have no sales in a month?

    You are still required to file a “Nil” GST R-3B. Failure to do so will result in late fees.

  5. What happens if I don’t file GSTR-3B for two consecutive months?

    Your GSTR-1 filing facility will be blocked, and your E-Way Bill generation facility will be suspended until the pending returns are cleared.
