All taxpayers who have registered under GST are required to file their GST returns as per GST Law. By filing these returns, taxpayers and the government get clarity on the amount of GST to be paid. To file these returns correctly and with minimal fuss, the taxpayer must have GST-compliant invoices for both sales and purchase transactions. GSTR 1 is a crucial form that must be completed in order to start the process of filing of these returns. This is because the information submitted in GSTR 1 serves as the foundation for auto-populating all other forms.
In this article, we will understand what is GSTR-1, including the sections under it, when it is due, who is liable to file it, and penalties for late filing. After reading this article, you should be a step closer to ensuring your business is GST-compliant.
Return filing can be a complicated process. To make it easier, consider investing in a robust GST Accounting Software that makes GST compliance smooth.

The turnover of a business determines its GSTR-1 due date. GSTR-1 returns must be filed either monthly or quarterly, depending on the business’s turnover. Businesses can file GSTR-1 and GSTR-3B quarterly if their annual revenue is up to ₹5 crore and they have opted for the QRMP Scheme; otherwise, they must file monthly returns if their annual turnover exceeds ₹5 crore.

Each registered dealer must complete the GSTR 1 filing process. The same is required and unaffected by the transactions that occurred that month. If you are a registered dealer, you must complete the GSTR-1 filing process even if there are no sales or transactions (this is called filing Nil returns). However, the following people or companies are excluded from submitting GSTR 1:
You must have a 15-digit PAN-based GSTIN and be a GST-registered taxpayer.
You must maintain detailed invoices with distinct serial numbers for your transactions, including intrastate and interstate transactions, business-to-business (B2B), and retail (B2C) sales. This also covers stock transfers between your company’s locations in other states and transactions involving exempt and non-GST products.
To validate your return using an EVC (electronic verification code) or a digital signature certificate, you must either have an OTP from your registered phone (class 2 or higher). Using an Aadhar-based e-sign, you can also submit your GST returns.

Nil Return | ₹20 (₹10 CGST + ₹10 SGST) | ₹500 (₹250 CGST + ₹250 SGST) |
