Implementing Goods and Services Tax has transformed how individuals and businesses pay taxes. However, there are several aspects of GST that people are not entirely familiar with regarding the filing of GSTR-3B or, to say, what is GSTR-3B return.

What Is GSTR-3B?

If you are wondering what is GSTR-3B, you have come to the right place. Let’s dive in for an in-depth understanding of what GSTR-3B is and why it is important for organizations to adhere to its rules.

Taxpayers registered under the GST regime in India have to pay GSTR-3B monthly. The GSTR-3B is a cumulative summary of the return of inward and outward supplies and input tax credit claimed. The Government of India has introduced this system to provide relaxation and reduce discrepancies. In other words, taxpayers file the GSTR-3B returns, disclose the supplies made during the month and the GST paid, seek input tax credit claims, and reverse charges on specific purchases.

GSTR-3B return must be filed even though there are no transactions in the relevant month. Also, there is a prescribed due date before which returns filing must be completed. After that due date, fines and penalties are attested on filing late returns.

What Is 3B In GST?

3B is a self-declaration form in the GST scheme. This process is framed for business owners registered under GST to declare their monthly purchases and sales.

Who Should File GSTR-3B?

All the businesses that are registered under the GST system have to compulsorily file  GSTR-3B on a monthly basis. Income slabs are provided on which the GSTR-3b has to be filed. But there are some entities that are exempted from filing GSTR-3B. They are as follows:

  1. Taxpayers registered under the composition scheme.
  2. Input service distributors.
  3. Non-resident suppliers of OIDAR (Online Information Database Access and Retrieval) services.
  4. Non-resident taxable person.

When Do You Need To File The GSTR-3B Return?

It is important to know when to file the GST-3B returns. There are many tools available in the market to help you automate and streamline the process.

Mainly there are two divisions that must be considered when filing GSTR-3B. They are as follows.

  1. The first part is for businesses whose annual turnover exceeds 5 Crores. Their due date is the 20th of every month. 
  2. The second part is for the businesses whose annual turnover is less than or equal to 5 Crores, 2 due dates have been provided for this division, i.e., the 22nd and 24th of every month, depending on the state where the business is situated. 

For example, you should file the GSTR-3B for April by the 20th of May if your annual turnover is greater than 5 Crores. If the annual turnover is less than or equal to 5 Crores and your business is situated in states like Gujarat, Maharashtra, Kerala, and Tamil Nadu, then the due date for filing GSTR-3B is 22nd May. However, if the business is in states like Delhi, Haryana, Punjab, Rajasthan, etc., the due date for filing GSTR-3B is 24th May.

Consequences Of Late Filing Of GSTR-3B

Late fees and penalties are levied on the tax payable if the filing is done post the due date. The charges accrued on the outstanding tax are as follows:

  • Rs 50/day for delay.
  • Rs 20/ day for registered business owners filing nil returns. However, the maximum late fee charged shall be capped at Rs 500 only for filing Nil GSTR-3B, i.e., Rs 250 for CGST and SGST each.

If there is a tax liability on a taxpayer for April and he is liable to pay tax on or before 20th May, and he misses the due date and pays the tax on 30th May, then counting from the 21st May fine of Rs 50/day will be levied till 30th May. So he will have to pay a fine of Rs 500 in addition to the tax payable.

GSTR-3B filing due date

Similarly, If an assessee has nil tax liability and has to file a nil GSTR-3B before 20th May for the tax period of April and fails to pay before the due date and pays on 30th May. Then counting from 21st May fine of Rs 20/day will be levied till 30th May.

How to File Nil GSTR-3B?

Nil GSTR-3B has to be filed by the entities falling under the following criteria during the particular tax period:

  • If there is no sale or purchase of any goods or services.
  • There is no reverse charge liability.
  • There is no intention of claiming any input tax credit.
  • Have no liability during the specific tax period.

Then the registered taxpayers need to file a nil GSTR-3B return. This form can be filed in two modes:

  1. Online through the GST portal.
  2. Offline via SMS.

Frequently Asked Questions


The basic and essential difference between GSTR-1 and GSTR-3B is as follows:

  1. Meaning: GSTR-1 is to be filed monthly or quarterly based on the assessee's turnover. The assessee has to provide all the relevant information regarding outward supplies i.e., sales or turnover. At the same time, GSTR-3B is a self-assessment return that must be filed monthly. The assessee must provide all the information regarding the purchase and sales.
  2. Filing Date: If the annual revenue of the assessee exceeds Rs 1.5 Crores in the previous or current year, then the due date to file GSTR-1 of the current month is the 11th day of the next month. However, if the annual turnover is less than Rs 1.5 Crores, then GSTR-1 can be filed quarterly, and the due date to file quarterly returns will be the 30th or 31st day of the month after the quarter. Irrespective of the assessee's turnover, GSTR-3B has to be filed monthly, and the due dates are mentioned in the blog in detail.
  3. Tax Payable: While filing GSTR-1, the assessee has to pay no amount of tax. Whereas in GSTR-3B, filing is completed only after paying the outstanding tax. Even in the case of no tax liability, the assessee has to file a nil return.
  4. Penalties: A penalty of Rs 200/day is levied on the assessee for filling GSTR-1 after the due date. For nil GSTR-3B return, the penalty is Rs 20/day post the due date and Rs 50/day in case of taxable return.
