GSTR-3B Filing on GST Portal – Step-by-Step Return Filing Procedure

GSTR-3B Filing on GST Portal

With the advent of GST, various changes have been made in the tax regime. Apart from unifying a myriad of indirect taxes, various new compliances were introduced. The authorities have formulated various forms to make the tax filing process even more seamless and straightforward for taxpayers. These forms are required to be filed by taxpayers within the stipulated time to avoid penalties or any adverse consequences. One such form is GSTR-3B, which is to be filed to declare the summary tax liabilities for a particular tax period. In this article, we will discuss how to file GSTR-3B and what are the procedural technicalities involved in filing this form.


GSTR-3B is a monthly return required to be filed by the registered taxpayer along with GSTR-1 and GSTR-2 Forms. It is a simplified return filed in order to declare the summary tax liabilities of a particular period. It is a mandatory requirement which is to be met even if there have been no business transactions during that particular period. In such a case, a Nil GSTR-3B is to be filed. However, there are a few entities that have been exempted from this mandatory compliance, which are as follows:

  • Input Service Distributors & Composition Dealers
  • Suppliers of Online Information Database Access and Retrieval Services (OIDAR)
  • Non-Resident Taxable Person.

Apart from the above-mentioned entities, GSTR-3B must be submitted by any taxpayer who is liable to file monthly returns. It is noteworthy that the government has mandated that GSTR-3B is to be filed by the registered taxpayers by the 20th of the succeeding month, i.e. the GSTR-3B for the month of October is to be filed by the 20th of November.

Furthermore, the government of India has relaxed the norms for businesses that have an aggregate turnover of less than Rs 5 crores by allowing them to file GSTR-3B on a quarterly basis, and this information will be auto-populated from GSTR-3B while filing GSTR-1.
