If your company has an annual turnover of up to Rs. 5 crore, you can file GSTR 1 quarterly under the QRMP scheme. The due date is the 13th of the month in the relevant quarter. If you have not registered for the QRMP scheme or your business’s annual turnover is more than Rs. 5 crore, you must submit the GSTR 1 form monthly for every month before the 11th of the next month.

You must understand the significance of due dates because late filing of GSTR 1 will result in late fees and penalties. Not filing GSTR 1 is an offence, and you might face fines and legal charges. Every registered taxpayer must submit GSTR 1 on or before the due date for all sales transactions. Even if your business didn’t complete any sales for the current month, you must file GSTR 1 for the next month, indicating that no outward supply has been made. This is called nil GSTR 1 filing and can be done through SMS now. However, the following persons need not file GSTR 1:

  • Composition dealers
  • Input service distributors
