GSTR-1 Filing: Meaning, Eligibility, Due Dates, & Penalty

GSTR-1 means a monthly or quarterly sales return filed by every GST-registered taxpayer to report details of all outward supplies of goods and services during a particular tax period. The GSTR-1 return contains details of sales invoices, debit and credit notes, and other outward supply details. Taxpayers must ensure a valid GSTIN is filled in while entering sales invoice details. It can be filed through the GST portal by entering all the details in the 13 sections of the GSTR-1 form. Registered dealers’ annual aggregate turnover limit determines whether they are eligible for monthly or quarterly returns.

What is GSTR-1?

GSTR-1 stands for Goods and Services Tax Return 1. It's a monthly (or quarterly for eligible taxpayers) filing mandated by the Indian government for businesses registered under the Goods and Services Tax (GST) system. In simpler terms, it's a report submitted to the GST authorities that details all the outward supplies of goods and services you made during a specific tax period. This includes sales to registered businesses, unregistered customers, and any credit or debit notes issued. By filing GSTR-1, you provide the government with a record of your taxable transactions, which helps them track and collect GST efficiently.

GSTR-1 Due Date

The due date for filing GSTR-1 depends on the taxpayer's annual aggregate turnover and whether they have opted for the QRMP (Quarterly Return Monthly Payment) scheme.

• Monthly Filing: Taxpayers with an annual aggregate turnover exceeding ₹5 crore, or those who have not opted for the QRMP scheme, must file GSTR-1 on a monthly basis. The due date for monthly filing is the 11th of the following month.
• Quarterly Filing: Taxpayers with an annual aggregate turnover of up to ₹5 crore and who have opted for the QRMP scheme can file GSTR-1 quarterly. For quarterly filers, the due date is the 13th of the month following the relevant quarter.

Below, we provided the table capturing the GSTR-1 Filing Due Dates at a Glance:

Category	Annual Aggregate Turnover	Due Date
Monthly Filers	More than ₹5 crore (or not opted for QRMP)	11th of the following month
Quarterly Filers (QRMP scheme)	Up to ₹5 crore	13th of the month following the relevant quarter

Note: Double-check and ensure the filled details are correct. The GST framework doesn't allow the revision of filed GSTR-1 returns. However, mistakes can be rectified in the GSTR-1 for the following filing period (month or quarter). For instance, if you find a mistake in your July 2024 GSTR-1, you can rectify it in the August 2024 GSTR-1 or any subsequent month's filing.  

Who can file GSTR 1?

Every registered dealer is liable to file GSTR 1 regardless of sales and turnover for a particular month, which means that even when there is no sale or transaction (Nil GSTR-1), a registered dealer has to file GSTR 1. Here is the list of people who are exempt from filing the GSTR 1:

An Input Service Distributor: If your business receives invoices for services used by your branches, then you are in the category of the Input Service Distributor under GST.

Composition Scheme Dealer: If you have registered under the Composition scheme, you are a composition scheme dealer and are not required to file this GST return.

A supplier of online Information, database access, or retrieval services.

Non-resident taxable person: If you import goods and services from outside India or manage the business on behalf of a Non-Resident Indian.

A Taxpayer who is liable for collecting Tax at Source or a taxpayer for deducting Tax at sources (TDS).
