A GST return is a mandatory document submitted by every registered taxpayer under the Goods and Services Tax framework, containing details of outward supplies (sales), inward supplies (purchases), Input Tax Credit (ITC) availed, and the net tax payable or paid. Depending on the taxpayer’s category and turnover, returns are filed monthly, quarterly, or annually through the GST portal. Non-filing attracts late fees of Rs. 50 per day and interest at 18% per annum on unpaid tax.
What Is a GST Return?
A GST return is an official declaration submitted by a registered taxpayer providing a comprehensive account of all financial transactions during the tax period. It covers revenue from outward supplies, expenses on inward supplies, GST collected from customers (output tax), GST paid on inputs (input tax credit), and the net tax liability after adjusting ITC against output tax.
Tax authorities use return data to determine the taxpayer’s net GST liability, verify ITC claims, identify compliance gaps, and track revenue collection.

Key Returns Explained
GSTR-1: Outward Supply Return
GSTR-1 captures invoice-level details of all outward supplies, including B2B invoices, B2C sales, exports, credit and debit notes, and HSN summary. The data flows into recipients’ GSTR-2B for ITC verification. From January 2025, HSN Phase III requires dropdown HSN code selection with separate B2B and B2C tabs.
GSTR-3B: Summary Return
GSTR-3B is the monthly or quarterly summary return for declaring output tax liability, claiming ITC, and making GST payments. From October 2024, the Invoice Management System (IMS) allows recipients to verify supplier invoices before they flow into GSTR-2B and ultimately into GSTR-3B.
GSTR-9: Annual Return
GSTR-9 consolidates the entire financial year’s GST compliance data including all outward and inward supplies, ITC availed and reversed, tax payments, refunds claimed, and demands raised. It must be filed by December 31 of the following financial year.
CMP-08 and GSTR-4: Composition Returns
Composition dealers pay tax quarterly through CMP-08 self-assessment challans (due by the 18th of the month after each quarter) and file an annual return in GSTR-4 (due by April 30 of the following FY). Composition dealers pay GST at fixed rates on turnover and cannot claim ITC on regular purchases.
Late Fees and Penalties
| Return | Late Fee (Per Day) | Maximum Cap | Nil Return Late Fee |
| GSTR-1 | Rs.50 (Rs.25 CGST + Rs.25 SGST) | Subject to a cap per notification | Rs. 20 (Rs.10 CGST + Rs. 10 SGST) |
| GSTR-3B | Rs.50 (Rs.25 CGST + Rs.25 SGST) | Subject to a cap per notification | Rs. 20 (Rs.10 CGST + Rs.10 SGST) |
| GSTR-4 | Rs.50 (Rs.25 CGST + Rs. 25 SGST) | Rs. 2,000 per return | Rs. 0 (Nil returns under amnesty) |
| GSTR-9 | Rs. 200 (Rs.100 CGST + Rs.100 SGST) | 0.5% of turnover in the state | Not applicable |
| GSTR-10 | Rs. 200 (Rs.100 CGST + Rs.100 SGST) | Rs.10,000 | Not applicable |
In addition to late fees, interest at 18% per annum is charged on the outstanding tax liability from the due date until the date of payment. Non-filing of GSTR-3B for two consecutive months blocks e-way bill generation for the defaulting GSTIN.
QRMP Scheme for Small Taxpayers
The Quarterly Return Monthly Payment (QRMP) scheme allows taxpayers with aggregate turnover up to Rs. 5 crore to file GSTR-1 and GSTR-3B quarterly instead of monthly. However, tax must still be paid monthly using either the fixed sum method (35% of cash paid in the last quarter) or the self-assessment method (actual liability for the month).
QRMP taxpayers can optionally use the Invoice Furnishing Facility (IFF) to upload B2B invoices in the first two months of each quarter, enabling their buyers to claim ITC without waiting for the quarterly GSTR-1.

Frequently Asked Questions
Q1: How many GST returns does a regular taxpayer file in a year?
A monthly-filing regular taxpayer files 12 GSTR-1 returns, 12 GSTR-3B returns, and 1 GSTR-9 annual return, totalling 25 returns per year. QRMP quarterly filers submit 4 GSTR-1, 4 GSTR-3B, and 1 GSTR-9, totalling 9 returns.
Q2: What is the penalty for not filing GSTR-3B on time?
Late filing attracts Rs. 50 per day (Rs. 25 CGST + Rs. 25 SGST) subject to a maximum cap. Additionally, interest at 18% per annum is charged on the unpaid tax from the due date. Non-filing for 2 consecutive months blocks e-way bill generation.
Q3: Can composition dealers claim Input Tax Credit?
No. Composition dealers cannot claim ITC on regular purchases. They pay tax at a fixed rate on turnover and file quarterly CMP-08 challans and annual GSTR-4. ITC on reverse charge supplies is the only exception.
Q4: What is the QRMP scheme, and who can opt for it?
QRMP allows taxpayers with turnover up to Rs. 5 crore to file GSTR-1 and GSTR-3B quarterly instead of monthly. Tax must still be paid monthly. The scheme reduces filing frequency while maintaining ITC flow through the optional Invoice Furnishing Facility.
Q5: Is GSTR-9 mandatory for all taxpayers?
GSTR-9 is mandatory for all regular taxpayers. Composition dealers file GSTR-4 as their annual return. Taxpayers with turnover up to Rs. 2 crore were previously exempt from filing GSTR-9 for certain years under specific notifications; the current applicability should be verified.
