GSTR 1 - Sales Return

GSTR-1 is a sales return that is required to be filed by every GST registered person. Tax payers are to enter details relevant to their sales & outward supplies in the GSTR 1 sales return.

What is GSTR 1?

The Goods and Services Tax Return 1 is a document that each registered tax payer needs to file every month/quarter.

How to file GSTR 1

The GSTR 1 format consists of a variety of information such as the taxpayer’s sales and outward supplies. Let’s take a look at each section in detail.

The first section asks for the year and the tax period for which the GSTR-1 is filed. The following sections ask for the tax details from that period.

Verification in GSTR-1 filing

At the end of the document, there is a declaration of truth that needs to be signed by the authorised signatory of your company.

Note: If you are using a GST compliant accounting and tax filing software (like Zoho Books), then the GSTR-1 will be auto-generated based on the transactions you record within the software. You can then push, reconcile and file this return directly into the GSTN.

GSTR-1 for different businesses

There are 13 tables and sections under GSTR 1. While each one is meant to capture a particular aspect of sales and outward supplies made under GST, not all of them are mandatory for every business (except for tables 1, 2, 3, 12 and 13 which are mandatory for all businesses). Hence, we have come up with a list of applicable GSTR 1 fields for a few business models.   There are 3 things under GST that dictate the type of information you need to file within GSTR-1: 

Your customer segment


The nature of supplies you make

Under the GST regime you can make 5 kinds of supplies - Taxable supplies/GST supplies, Nil rated supplies, Zero rated supplies, Exempt supplies and Non-GST supplies. You can learn more about each kind of supply here.

Mode of supply

The two common modes of supplying goods and/or services are direct supplies and online supplies (those made through an e-commerce operator like Flipkart or Shopclues).

General Notes

While this may not apply for your July return (since it will be the very first GSTR-1 that you will file), from the next GSTR-1, you can make amendments (or legal modifications) to the data filed by you previously using tables 9 and 10.
