GSTR 3B Due Date: Monthly, Quarterly & Late Fee

Submission of GST returns promptly is not only a legal requirement of any registered taxpayer in India, but it is also part of good financial management of a business. Among all GST returns, GSTR 3B plays a central role in compliance.

It is the summary return each usual GST-registered taxpayer is required to define and state their tax payable and input tax credit (ITC), in addition to the net taxes payable within a period. Missing the GSTR 3B due date may incur a penalty, interest, and even interruption in ITC claims.

What Is GSTR 3B, and Who Should File It?

The first step to timely and accurate compliance is to understand the basics of GSTR 3B. The section is about the form overview, applicability, and turnover limits.

Overview Of GSTR 3B

Every regular registered taxpayer is required to file GSTR 3B. It is a summary GST return that reports total outward supplies, ITC claimed, and net tax liability. GSTR 3B is all about summary numbers you don’t need to enter every invoice, unlike GSTR 1, which asks for all the details.

Once GSTR 3B is filed, it cannot be revised. Therefore, careful review before submission is essential. So review your numbers thoroughly before you hit submit. And even if you didn’t have any transactions that month, you still need to file it.

Who Is Required To File GSTR 3B?

All regular taxpayers registered under GST must file GSTR 3B.The classes that are, however, exempt from this duty are:

• Registered taxpayers on the Composition Scheme
• Input Service Distributors (ISDs)
• Non- resident taxable individuals
• Non-resident suppliers of Online Information and Database Access or Retrieval (OIDAR) services

A different GSTR 3B will be required for each GSTIN. Clubbing two registrations with the same PAN is not possible.

What Is The Turnover Limit For GSTR 3B?

The frequency of filing is determined by the turnover limit of GSTR 3B. The QRMP ( Quarterly Return Monthly Payment) scheme can be availed by taxpayers with an aggregate annual turnover of up to 5 crore, and they need to submit GSTR 3B quarterly.

In case taxpayers have an aggregate annual turnover of more than Rs. 5 cr, they have to file GSTR 3B on a monthly basis without exception.

GSTR 3B Due Date Monthly

The due date of GSTR 3B is a recurring monthly compliance requirement for most GST-registered businesses in India. The knowledge of the specific dates and state-wise the organisation will prevent the rush and penalty at the last moment.

What Is The Due Date For GSTR 3B?

What is the due date for GSTR 3B? When monthly filers are involved, the usual date of standard GSTR 3B is the 20th of the next month. Taking the example, 20th February is the due date of the GSTR 3B in respect to January.

This applies to a fixed date for taxpayers whose annual turnover is over Rs. 5 crore, as well as those who have not chosen the scheme QRMP.

State-Wise Due Date Structure For Monthly Filing

The general due date remains as 20 th, but the government has varied due dates of various categories of taxpayers, depending on their state/UT of registration.

Certain states might also differ in the schedule of the taxpayers on the basis of notifications by the CBIC. One should always remember to look at the official GST portal or the GST Calendar to confirm the latest state-wise due dates.

GSTR 3B Due Date Quarterly

The QRMP scheme, which was implemented in January 2021, gave much relief to small taxpayers as it enabled them to submit the returns on a quarterly basis. The GSTR 3B due date quarterly is, however, not in the format of monthly, but varies between the state categories.

GSTR 3B Due Date For Quarterly Return Under QRMP Scheme

The 22 nd or 24 th day of the month after the end of your quarter is the preferred day to submit your quarterly return under the QRMP scheme.

The due date will be determined by the state or UT in which the principal place of business of the taxpayer is registered. As an example, quarterly GSTR 3B would be submitted by 22 nd or 24 th October to the quarter ending December 31.

GSTR 3B Due Date Quarterly Based On State Categories

The two categories are states and Union Territories that must file quarterly GST returns (GSTR 3B):

GSTR 3B Due Date Extended

At times, the government also gives the taxpayers who are actually in hard times a relief by extending the GSTR 3B due date. The question of the timing and how these extensions are granted is of relevance to compliance planning.

Situations When GSTR 3B Due Date Extended

The CBIC usually issues the GSTR 3B due date extensions notifications in the following cases:

• Natural disasters like floods, cyclones, earthquakes, etc., impact huge masses of taxpayers.
• The GST portal has technical glitches that do not allow timely filing.
• Emergencies in the area of public health or other uncommon situations.
• Administrative rulings to have more time to go before big system changes.

An example is during August 2025, the GST 3B due date of July 2025 was postponed to 27th August instead of 20 th August in some districts hit by heavy rainfall in Maharashtra.

In the same way, the September 2025 due date was altered to 25th October 2025 instead of 20 th October 2025 throughout the board.

Late Fee And Penalty For GSTR 3B

Late application of the GST3B due date is subject to a late fee and interest. Such fees will add up very fast, and filing them on time is vital to every taxpayer.

Late Fees Applicable For Non Filing

The late fee structure for GSTR 3B is as follows:

• Rs. 50 per day of delay (Rs. 25 each under CGST and SGST) for taxpayers with a tax liability
• Rs. 20 per day of delay (Rs. 10 each under CGST and SGST) for taxpayers with nil tax liability
• The maximum late fee that can be charged is capped at Rs. 10,000 per return

Interest On Delayed Tax Payment

Apart from late fees, interest at the rate of 18% per annum is charged on the outstanding tax amount from the due date until the date of actual payment. Interest is calculated on the net tax payable after adjusting available ITC in the cash ledger.

This means that even if a taxpayer files the return late but had already deposited tax in the cash ledger, interest may still apply on the unpaid portion.

Waiver And Reduction Of Late Fees by the Government

The government has, from time to time, issued amnesty schemes and waiver notifications to reduce the burden of accumulated late fees.

Taxpayers who have not filed returns for past periods should check whether any such relief is currently available before filing pending returns.

How Late Fee Is Calculated Under Different Tax Heads

Late fee is levied separately under the CGST and SGST heads. There is no late fee under IGST.

To a taxpayer who has a tax liability, the amount of the late fee is Rs. 50 per day is divided in half, Rs. 25 under CGST and Rs. 25 under SGST, on each day of delay after the due date.
