How to file GSTR-1 on GST Portal

The GST Council in its meeting on July 2-3 had shared a revised format for returns which are required to be filed under the GST regime. In this article, we will discuss the revised heads and the new format.

In our previous article, we have discussed all the returns that are required to be filed under Goods and Services Tax. We have also discussed the different types of returns applicable to a specific taxable person such as Input Service Distributor, E-Commerce Operator etc.

According to the GST law, every registered taxable person is required to submit the details of outward supplies in the GSTR-1. This return is required to be filed within 10 days from the end of the tax period, or the transaction month (in simple words).

GSTR-1 has a total of 13 headings. However, the taxable person need not worry as most of these will be prefilled. Before we dive deep into the various sections of this return, we need to understand certain terms. These are:

  1. GSTIN – Goods and Services Taxpayer Identification Number

  2. UID – Unique Identity Number for Embassies

  3. HSN – Harmonized System of Nomenclature for goods

  4. SAC – Services Accounting Code

  5. GDI – Government Department Unique ID where department does not have a GSTIN

  6. POS – Place of Supply of Goods or Services – State Code to be mentioned.

Below are the various section headings under GSTR-1:

  1. GSTIN: Each taxpayer will be allotted a state-wise PAN-based 15-digit Goods and Services Taxpayer Identification Number (GSTIN). The format of proposed GSTIN has been shown in the image below. The GSTIN of the taxpayer will be auto-populated at the time of return filing.
