GSTR-3B: Return Filing, Format, Eligibility & Rules

If you own a business and hold a GSTIN, you are liable to file a monthly or quarterly GSTR-3B return. Avoid unnecessary and untimely demand letters from the IT department by filing your GSTR-3B on time every time. If you are not sure what we are talking about then read on.

GSTR-3B Return

What is GSTR-3B

GSTR-3B or GST Return form 3B is a self-assessed summary of GST returns filed every month, or quarterly in case of QRMP (Quarterly Return Filing and Monthly Payment of Taxes) eligible taxpayers. GSTR-3B was introduced as soon as GST was rolled out in July 2017.

Some of the important points about GSTR 3B are

  • A GSTR-3B can only be submitted for a single GSTIN.
  • Any GST liability should be cleared on or before the due date of GSTR 3B filing.
  • GSTR-3B filing cannot be revised once filed.
  • GSTR-3B is a must even in cases of zero liability

GSTR-3B Eligibility

GSTR-3B is mandatory for every GSTIN with a few exceptions which are listed below.

  •  Input service distributors (ISD)
  • Registered taxpayers covered under the Composition Scheme
  • Non-resident suppliers of OIDAR (Online Information Database Access and Retrieval) services
  • Non-Resident Indians who are registered tax-payers
  • Small taxpayers with a turnover of less than 5 crores. They are required to file GST-PMT 08, a self-assessed quarterly payment of taxes.

GSTR-3B Late Submission Fee And Other Penalties.

If you don't file the GSTR-3B within the due date, a late fee is charged as below:

  • Rs. 50 per day is calculated from the due date.
  • Rs. 20 per day is levied for taxpayers with nil liability.

A penalty of 18% per annum is charged on the total outstanding tax, in cases where the GST dues are not paid by the due date. 

Important Dates for GSTR-3B Filing

Until December 2019, GSTR-3 B’s due date was the 20th of the subsequent month. There has been a change in the schedule starting January 2020. The new due dates are based on the annual turnover and your location.

After Jan 2020, the following rules apply:

  • If your annual turnover is greater than 5 crores, the due date for GSR-3B filing is the 20th of every month.
  • If your annual turnover is less than or equal to 5 crores, the due date is determined by the state you are located in. The table below shows the dates for various states and union territories.
  • For those in the QRMP scheme, 22nd or 24th of the month following every quarter as per the above classification of states and UTs.

  • Most important of all, if the tax amount due was paid on time, but GSTR-3B was filed after the deadline, the late fee will still apply.
  • Finally, those taxpayers who file quarterly GSTR-1 returns are still required to pay tax and file GSTR-3B every month.

GSTR-2A is used for the real-time update of ITC (Input Tax Credit). GSTR-2B is nothing but the listing of all applicable ITC for the given month (ITC statement).

Both GSTR-2A and GSTR-2B should be used along with GSTR-3B to reconcile Input Tax credits.

It is critical that you go through both GSTR-2A and GSTR-2B before attempting to file GSTR-3B

By using them together, you could

  • Avoid mismatches and avoid notices for claiming excess input tax credits.
  • Avoid missing genuine input tax credits.
  • Stay GST compliant.
