GST-Understanding GSTR-1

GST filing is one of the most important tasks that every registered business has to undertake. While businesses are supposed to ensure they stay on top of all their filing requirements, GST filing can get a bit confusing due to the many different interlinked forms. Keep reading this article to get an answer to all your doubts regarding GSTR 1.

What is GSTR 1?

GSTR1 is a monthly return or a quarterly return form that every registered dealer is required to file. For most taxpayers, GSTR-1 needs to be filed monthly. In this form, the GST-registered dealers must provide all the details of their outward supplies or sales of Goods and Services. 

When is it due?

The due date for GSTR 1 is based on the taxpayer’s Annual turnover. Businesses that have a turnover of a minimum of 5 crores are required to file GSTR-1 monthly and are supposed to file the same on or before the 11th of the upcoming month. However, businesses with a turnover below 5 crores (Amended vide GST Circular No: Circular No. 143/13/2020- GST) can opt for filing GSTR-1 quarterly, and the due date to file it is on or before the 13th of the month succeeding the end of every quarter. For example, the monthly GSTR-1 for the month of March needs to be filed by 11th of April; the quarterly GSTR-1 for the quarter April-June needs to be filed by 13TH July.
