GST Return Filing

GST Return Filing

What are GST returns?

Every GST-registered business must report its sales, purchases and tax paid to the government through returns on the GST portal. The two main returns are:

  • GSTR-1: details of your outward supplies (sales), invoice by invoice for B2B customers and in summary for retail customers. Usually due by the 11th of the following month.
  • GSTR-3B: a summary return where you pay the net tax after claiming input tax credit. Usually due by the 20th of the following month for monthly filers.

Businesses under the composition scheme file CMP-08 quarterly and GSTR-4 annually instead.

Monthly or quarterly: the QRMP option

Small businesses with turnover up to ₹5 crore can choose the Quarterly Return Monthly Payment (QRMP) scheme. You file GSTR-1 and GSTR-3B every quarter and pay tax monthly through form PMT-06. Using the Invoice Furnishing Facility (IFF), you can still upload B2B invoices monthly so your customers get their credit on time. We help you pick the option that suits your cash flow and customer base.

Why timely filing matters

  • Avoid late fees and interest: fees are charged for each day of delay, plus 18% interest on unpaid tax.
  • Protect your customers’ credit: if you miss GSTR-1, your B2B customers cannot claim input tax credit, and they may hold your payment.
  • Keep your registration active: continuous non-filing can lead to suspension or cancellation of your GSTIN.
  • Avoid notices: mismatches between GSTR-1, GSTR-3B and GSTR-2B often trigger notices from the department.

Frequently Asked Questions

Do I need to file GST returns if I had no sales this month?

Yes. Every registered business must file its returns even when there are no sales. A nil return can be filed quickly, but missing it still attracts a late fee.

What is the QRMP scheme?

Businesses with annual turnover up to ₹5 crore can file GSTR-1 and GSTR-3B quarterly instead of monthly, while paying tax every month through a simple challan.

What happens if I file GST returns late?

Late filing attracts a daily late fee, and unpaid tax carries 18% annual interest. Repeated non-filing can lead to suspension or cancellation of your GST registration.

Why is my input tax credit lower than my purchase bills?

You can only claim credit that appears in GSTR-2B, which depends on your suppliers filing their GSTR-1. We reconcile your purchases every month and follow up on missing invoices.
