Goods and Services Tax was introduced in India to eliminate the cascading effect of taxes. GST has been effective from the 1st of July 2017.

 GST has now subsumed most indirect taxes like VAT, Excise, Service tax etc. This has simplified the taxation structure and has brought uniformity between all the states in terms of taxation structure.

In this detailed article, we explain the major returns under GST and give a brief overview of each GST return.

What does GST Return filing mean?

GST return forms are the documents to be furnished on the GST portal monthly, quarterly or annually.

Taxpayers are required to furnish all the sales & purchase related details, GST Input Tax Credit details, and all the other taxes paid on the sales and purchases of goods & services.

These details must be furnished via a common government portal, ‘GST Network Portal’.

Who is eligible to register under the GST structure?

Following individuals/entities are eligible to be registered under the GST tax structure:

  • Taxpayers registered under previous tax systems like VAT, Excise, etc.
  • Vendors supplying products through E-commerce aggregators
  • Input Service Distributors

GST Registration eligibility depends on the annual aggregate turnover of the person, and this varies as per the categories of the state (Normal Category state or Special Category states).

Following is the turnover limit to be eligible for GST registration:

State category For sale of Aggregate turnover required for GST Registration GST Registration required?

Eligibility to file a GST Return

Major GST return types under GST

Following is the list of the major GST returns under GST. Most of these returns are common for most businesses, and hence, it is crucial to understand the importance of all these returns for a smoother GST return filing experience.

GSTR-1 return

  • GSTR-1 return captures all the outward sales data.
  • The taxpayer has to furnish all the outward sales details in his monthly or quarterly GSTR-1 return.
  • GSTR-1 is filed on a monthly or quarterly basis based on the annual aggregate turnover of the business.

What are GSTR-1 filing due dates?

Following are the GSTR-1 filing due dates based on the aggregated turnover of the taxpayer:

a. For taxpayers with a turnover of more than 1.5 Crore

  • These taxpayers have to file their GSTR-1 MONTHLY.
  • GSTR-1 filing due date for these taxpayers is the 11th of every succeeding month

b. For taxpayers with turnover up to 1.5 Crore

  • These taxpayers have to file their GSTR-1 QUARTERLY.
  • GSTR-1 filing due date for these taxpayers is the 13th of every succeeding month.

GSTR-2A return under GST

  • GSTR 2A is a tax return related to purchases of goods and services in a given month.
  • This return auto-generates from the GSTR 1 of the seller by the GST portal.
  • Any information filed in GSTR1 by the seller is captured in GSTR 2A of the purchaser.
  • GSTR 2A is an automatically generated return from the seller’s GSTR 1 for each business by the portal of GST.

GSTR-2B return under GST

  • GSTR-2B return is a static statement generated every month.
  • GSTR-2B is an auto-drafted statement generated for all the regular GST taxpayers.
  • GSTR-2B gets generated after the 12th of every month.
  • GSTR-2B gets generated based on the GSTR-1, GSTR-5 or GSTR-6 filed by the taxpayer.

How is GSTR-2B generated?

GSTR-2B contains all the eligible ITC of the month, and it is based on the details of GSTR-1 filed by your Supplier.

Let us understand this with the help of an example:

There’s a taxpayer named ‘Appu Retailers Ltd.’.

He has two suppliers:

  1. Gaurav Traders
  2. Abhinav Suppliers

Consider the following scenario:

1.The transaction with Gaurav Traders-

Recipient ‘Appu Retails’ makes a purchase of goods worth Rs.1,00,000 from this Supplier.

The transaction details between them are as follows-

Cost of goods= Rs. 1,00,000 

GST paid to Supplier = 28% = Rs. 28,000

Total amount Paid = Rs. 1,28,000

This Supplier files his GSTR-1 for this transaction correctly and before the due date.

2.Transaction with ‘Abhinav Suppliers’

Recipient ‘Appu Retails’ makes a purchase of goods worth Rs.2,00,000 from this Supplier.

The transaction details between them are as follows-

Cost of goods= Rs. 2,00,000 

GST paid to Supplier = 18% = Rs. 36,000

Total amount Paid = Rs. 2,36,000

This Supplier DOES NOT file his GSTR-1 for this transaction.

Now let us look at the Recipient’s side (Appu Retails)-

Considering there are only these two transactions in the month of January 2022:

Total GST paid to suppliers = Rs. 28,000 (to Supplier 1) + Rs. 36,000 (Supplier 2)

  = Rs. 64, 000 paid in GST

As per Recipient’s ‘Books of Accounts’ – Eligible ITC for month = Rs. 64, 000

But as per GSTR-2B of the Recipient, eligible ITC = Rs. 28,000

The primary reasons behind missing ITC of Rs. 36,000 (from supplier 2) could be:

  1. Supplier 2 has not filed his GSTR-1 for this transaction
  2. Supplier 2 filed his GSTR-1 AFTER the due date.

These two are the possible reasons for missing ITC in the monthly GSTR-2B summary.

This example elaborates the correlation between GSTR-1 & GSTR-2B and how delayed filing of GSTR-1 by your Supplier affects you as a recipient.
