GSTR-1, also known as the Goods and Services Tax (GST) Return 1, is a crucial document that registered taxable persons under the GST regime are required to file electronically on the GST Portal. This return provides a detailed account of all outward supplies of goods or services made by the taxpayer during a specific tax period. It serves as a comprehensive source of information for the Central and State tax authorities to assess the taxpayer's GST liability.

GSTR-1 Due Date

The due date for filing GSTR-1 depends on the taxpayer's turnover and filing frequency. For taxpayers with a turnover of more than ₹1.5 crore in the previous financial year, the due date for filing GSTR-1 is the 11th day of the succeeding month. For taxpayers with a turnover of up to ₹1.5 crore, the due date for filing GSTR-1 is the 13th day of the month succeeding the end of every quarter.

GSTR-1 Due Date for Quarterly Return

Taxpayers who file GSTR-1 quarterly have the following due dates:

Quarter 1 (April-June): 13th of July

Quarter 2 (July-September): 13th of October

Quarter 3 (October-December): 13th of January

Quarter 4 (January-March): 13th of April

GSTR-1 Due Date Monthly

Taxpayers who file GSTR-1 monthly have the following due dates:

Month 1 (April): 11th of May

Month 2 (May): 11th of June

Month 3 (June): 11th of July

Month 4 (July): 11th of August

GSTR-1 Late Fee

In accordance with GST regulations, the late fee for the non-submission of GSTR-1 is Rs 200 per day for delayed filing, comprising Rs 100 as per the CGST Act and Rs. 100 as per the SGST Act. This late fee is calculated from the day following the last filing date.

However, as per notifications issued until February 2021, there has been a reduction in late fees to Rs 50 per day and Rs 20 per day for nil returns. It's essential to emphasize that, at present, the GST portal does not mandate the payment of late fees for GSTR-1 as part of the payment challan in PMT-06 during the filing of GSTR-3B.

According to CGST notification 20/2021 dated June 1, 2021, the maximum late fee is applicable from June 2021 onwards.

Individuals who have no outward supplies in the tax period will not incur the maximum late fee of Rs 500 (Rs. 250 per Act). Conversely, individuals with a total turnover of Rs 1.5 crores in the previous fiscal year, excluding nil return filers, are subject to a maximum late fee of Rs 2000 (Rs. 1,000 per Act). Individuals with an average annual turnover exceeding Rs 1.5 crores but not exceeding Rs 5 crores in the previous fiscal year, excluding nil filers, may face a maximum late fee of Rs 5000 (Rs. 2500 per Act). There is no modification in the maximum late fee for assesses whose total turnover surpasses Rs 5 crores, and it remains fixed at Rs 10,000.
