GST Return Filing: Monthly and Quarterly Compliance Guide for Businesses

GST return filing is a critical compliance requirement for all businesses registered under GST in India. Whether you file monthly or quarterly returns, understanding the different return forms, due dates, and filing procedures is essential to avoid penalties. At Vidhi Legal Services, we help businesses in Kolkata stay compliant with all GST return filing requirements.

What are GST Returns?

GST returns are periodic statements that registered taxpayers must file with the tax authorities, providing details of sales, purchases, input tax credit claimed, and tax paid. The frequency and type of return depend on the business type and turnover.

Types of GST Returns

GSTR-1 (Outward Supply Details): Contains details of all sales (outward supplies) made during the period. This return must be filed monthly by regular taxpayers or quarterly by those opting for the Quarterly Return Monthly Payment (QRMP) scheme.

GSTR-3B (Summary Return): A simplified monthly summary return that includes consolidated details of outward supplies, input tax credit claimed, and tax paid. This is the most common return for regular taxpayers.

GSTR-4 (Composition Scheme Return): Filed annually by businesses registered under the Composition Scheme. Details of outward supplies, tax paid, and input tax credit are reported.

GSTR-9 (Annual Return): An annual consolidated return that must be filed by all regular taxpayers. It reconciles the monthly/quarterly returns filed during the financial year.

GSTR-9C (Audit Report): Filed by taxpayers whose annual turnover exceeds ₹5 crores. Requires certification by a Chartered Accountant.

GSTR-10 (Final Return): Filed when a taxpayer cancels GST registration. Must be filed within 3 months of cancellation or the date of cancellation order, whichever is later.

The Quarterly Return Monthly Payment (QRMP) scheme is available for businesses with turnover up to ₹5 crores.

• GSTR-1: Due by the 13th of the month following the quarter

Step-by-Step GSTR-3B Filing Process

Step 1: Log In to GST Portal

Visit www.gst.gov.in and log in with your credentials (GSTIN and password).

Step 2: Navigate to Returns Dashboard

Go to Services > Returns > Returns Dashboard. Select the financial year and return period (month).

Step 3: Prepare the Return

Fill in details of outward supplies, inward supplies (for reverse charge), input tax credit, and tax payment. The portal auto-populates some details from GSTR-1 and GSTR-2A.

Step 4: Payment of Tax

If there is a tax liability after claiming input tax credit, pay the amount through the challan. The payment can be made from the electronic credit ledger (ITC) or cash ledger.

Step 5: File and Verify

Submit the return and verify it using DSC or EVC. After verification, you will receive a success message and acknowledgment.

Late Fees and Penalties for Late Filing

• GSTR-1 Late Fee: ₹50 per day (₹25 CGST + ₹25 SGST) — maximum ₹5,000 per return
• GSTR-3B Late Fee: ₹50 per day (₹25 CGST + ₹25 SGST) — maximum ₹5,000 per return

Common GST Return Filing Mistakes

• Mismatch between GSTR-1 and GSTR-3B figures

Frequently Asked Questions

1. What happens if I miss filing my GST return?

Late filing attracts late fees as mentioned above. Additionally, you cannot file subsequent returns until the overdue return is filed. The GST registration may also be suspended for persistent non-compliance.

2. Can I revise a filed GST return?

GSTR-1 and GSTR-3B cannot be revised after filing. However, corrections can be made in subsequent returns. The amending return process has been simplified with GSTR-1A (a proposed form, not yet implemented fully).

3. Do I need to file GST return if there is no business activity?

Yes, even if there is no business activity (NIL sales/purchases), you must file NIL returns. Failure to do so attracts late fees.

4. What is the due date for GSTR-9 annual return?

The due date for GSTR-9 is December 31 of the following financial year. For example, for FY 2024-25, the due date is December 31, 2025.

5. Can I claim ITC if my supplier hasn't filed their GST return?

ITC can be claimed only when the supplier has filed GSTR-1 and the details appear in your GSTR-2A/GSTR-2B. Unmatched ITC must be reversed with interest.
