All GST-registered businesses in India are required to file a GST return that comprehensively discloses their sales, input tax credit (ITC) claims, tax liability, refunds and other relevant details recorded under their GSTIN. This return, filed through Form GSTR-3B, plays a pivotal role in ensuring regulatory GST compliance and financial transparency.

Filing this return through the official GST portal is straightforward, but it can pose challenges, such as increased error due to unfamiliarity with its format. This blog aims to simplify the GSTR-3B format and provide essential insights to help streamline the filing returns process.

What Is GSTR-3B Under GST?

what is gstr-3b under gst?

Form GSTR-3B is a self-declared summary return where taxpayers declare their GST liabilities for a specific tax period to fulfil them. A regular taxpayer must file this form for every tax period, reporting summary figures of sales, the balance of input tax credit (ITC) claimed, and net tax payable.

Each business entity registered under GST with a valid GSTIN must file a GSTR-3B. Even if there is no tax liability, filing GSTR-3B is mandatory. The liability you hold must be settled on or before the return’s filing date, which should not be later than the due date.

Late Fee & Penalty for GSTR-3B

A delay in filing GSTR-3B results in a daily late fee, starting from the due date and continuing until the return is filed. The late fee structure for GSTR-3B filing varies, depending on the type of taxpayer.

  • For normal taxpayers: If there is a tax liability, the late fee is ₹50 per day (₹25 for CGST and ₹25 for SGST).
  • For taxpayers with NIL tax liability: If there is no tax liability, the late fee is reduced to ₹20 per day (₹10 for CGST and ₹10 for SGST).

There is a cap on the maximum penalty, which is ₹10,000 (₹5,000 for CGST and ₹5,000 for SGST) for each return. Additionally, if the GST dues are not paid by the due date, an interest of 18% per annum is charged on the outstanding tax amount.

The due dates for filing GSTR-3B vary based on the filing frequency. For monthly filers, you need to submit your GSTR-3B by the 20th of the next month. If you are filing for June, you must submit it by July 20th.

Starting from January 1, 2021, taxpayers with an annual turnover of up to ₹5 crore have the option to file GSTR-3B quarterly under the QRMP scheme. If you are a part of this scheme, you can file your GSTR-3B returns for each quarter between the 22nd and 24th of the following month.

The specific due date may also vary depending on the state or union territory where your business operates. By adhering to the due date, taxpayers can ensure timely tax payments and avoid incurring substantial late fees and penalties.

In addition to late fees and interest, the non-filing of GSTR-3B returns can result in the following penalties:

  • Input Tax Credit (ITC) Restrictions

One of the major consequences of non-filing GSTR-3B is the limitation on claiming input tax credit (ITC). According to GST regulations, ITC can only be claimed if the supplier has reported their outward supplies in their GST returns on time. Failure to do so can result in increased tax liability for taxpayers.

  • Prosecution and Legal Consequences

In cases where a taxpayer repeatedly fails to file GST returns, including GSTR-3B, tax authorities may initiate legal proceedings. It is crucial for taxpayers to adhere to GST late filing due dates to prevent potential legal repercussions.

Recent Changes in GSTR-3B

Initially announced in July through Notification No. 14/2022 – Central Tax, the government subsequently implemented changes to the format of the GSTR-3B return in September. Notably, these changes revised the procedure for reporting data in Table 4 of the form. The updated format of Table 4 now provides a more detailed breakdown of input tax credit (ITC), including eligible, ineligible, restricted, reversed and reclaimed ITC, among other similar information.

Payment on GST Returns

The GST payment process remains largely uniform for all taxpayers under the GST regime. If there is enough cash balance in the electronic cash ledger, no additional payment is necessary. However, if the cash balance is insufficient, taxpayers are required to deposit money into the cash ledger using a prescribed challan and approved modes of payment.
