GSTR-4 Return Filing: A Complete Guide for Composition Taxpayers in India

If you are a small business owner registered under the GST Composition Scheme, GSTR-4 is one return you simply cannot afford to ignore. Whether you run a retail shop, a small manufacturing unit, or provide services under the special composition scheme. Understanding GSTR-4, what it is, when it is due, and how to file it, is essential to staying GST-compliant without attracting unnecessary penalties. In this guide, we will break down everything you need to know about GSTR-4. 

What is GSTR-4?

GSTR-4 is an annual GST return that must be filed by all taxpayers registered under the GST Composition Scheme. It covers the full financial year and includes details of outward supplies made, inward supplies received, imports of services, and any supplies attracting Reverse Charge Mechanism (RCM).

From April 1, 2019 onwards, any business that has opted into (or was part of) the Composition Scheme for any period during a financial year is required to file Form GSTR-4 as an annual return. The return is filed online through the GST portal and helps the government maintain a consolidated record of tax obligations for composition dealers.

In short, GSTR-4 is the year-end compliance snapshot for composition taxpayers, a single annual filing that replaces the earlier requirement of filing quarterly returns, from the 2019-20 financial year onward.

Who Needs to File GSTR-4? (Applicability)

GSTR-4 is applicable to all taxpayers who have opted for the Composition Scheme under GST for any period during the financial year. This broadly includes:

• Taxpayer who have opted for composition scheme since registration and have never opted out subsequently
• Taxpayers who have opted in for composition scheme before starting of the financial year
• Taxpayers who have opted in for composition but subsequently opted out any time during the year.

It is important to note that there is no separate turnover threshold for filing GSTR-4 itself. The eligibility condition is tied to the Composition Scheme registration. If you are a composition dealer, regardless of your exact annual turnover within the eligible limit, you are required to file GSTR-4.

Composition taxpayers must file a Nil GSTR-4 to remain compliant, even if there was no business activity during the financial year. GSTR-4 non-filing is not an option for composition taxpayers. 

What is the Due Date of GSTR-4 & When Do You Need to File?

The due date for GSTR-4 filing is 30th of the month succeeding the financial year or as extended by the Government from time to time. 

For FY 2025-26, the due date of GSTR-4 is 30th June 2026. 

Updated Due Date (From FY 2024-25 Onwards):

Earlier, the GSTR-4 was filed by 30th April of the year following the relevant financial year. Following the 53rd GST Council meeting, the due date was extended. As per CGST Notification 12/2024 dated 10th July 2024, the new due date for GSTR-4 from FY 2024-25 onwards is 30th June of the following financial year.

This is a significant update for small businesses, providing an additional two months to compile and file their annual return, a welcome relief from the earlier April 30 deadline.

What is the Difference Between GSTR-4 & GST CMP-08?

Many composition taxpayers get confused between GSTR-4 with CMP-08. GSTR-4 is an annual return for composition taxpayers while composition dealers pay taxes quarterly using Form CMP-08. Here is a quick difference between both for your reference: 

Think of CMP-08 as your quarterly advance tax payment, and GSTR-4 as your annual tax report card. Both are mandatory and complement each other.

GSTR-4 Format: What Does the Form Contain?

The annual GSTR-4 form is structured into nine tables, each capturing a specific aspect of the taxpayer's business for that financial year. Here is a section-by-section breakdown:

1. Tables 1–3: Basic Details (Auto-Populated)

These tables carry basic identification information including your GSTIN, legal name, trade name, and aggregate turnover from the preceding financial year. The Application Reference Number (ARN) and filing date get populated automatically after successful submission.

2. Table 4: Inward Supplies Including Reverse Charge:

This is one of the most critical sections. You need to report all inward supplies received during the year, segregated as:

• Supplies from registered suppliers (not attracting reverse charge)
• Supplies from registered suppliers attracting reverse charge
• Supplies from unregistered suppliers
• Imported services subject to reverse charge

Accuracy here is vital, any mismatch with supplier data could trigger compliance notices.

3. Table 5: Summary of Self-Assessed Tax Liability (Auto-Populated):

This table is auto-populated from your quarterly Form GST CMP-08 submissions. It consolidates the tax liability already declared and paid across all four quarters, covering outward supplies, reverse charge liabilities, taxes, and any interest dues.

4. Table 6: Tax Rate-Wise Details of Outward and Inward Supplies (RCM):

Here, you must provide a tax-rate-wise breakup of your outward supplies and inward supplies attracting reverse charge. The system then auto-calculates the applicable IGST, CGST, SGST/UTGST, and Cess amounts based on your entries.

5. Table 7: TDS/TCS Credit Received: 

If any of your buyers have deducted Tax Deducted at Source (TDS) or if you have received Tax Collected at Source (TCS) credit through an e-commerce operator, those details go here. You must include the GSTIN of the deductor/collector, invoice value, and the TDS/TCS amount.

6. Table 8: Tax, Interest, and Late Fee Payable and Paid:

This is the settlement table, showing:

• Tax payable (auto-populated from Table 6)
• Tax already paid through CMP-08
• Balance tax remaining to be paid
• Any applicable interest or late fee for delayed payments

If there is a balance after adjusting your CMP-08 payments, it must be cleared through the Electronic Cash Ledger before final submission.

7. Table 9: Refund from Electronic Cash Ledger: If you have excess tax credits in your Electronic Cash Ledger, perhaps due to over-payment through CMP-08, you can claim a refund in this section. You specify the amount to be refunded across tax, interest, penalty, and other categories.

8. Verification: Before filing, you are required to authenticate the return by digitally signing it. This confirms the accuracy of all details entered.

Step-by-Step: How to File GSTR-4 Online

Filing GSTR-4 on the GST portal is relatively straightforward once you have all your records in order. Here is the complete process:

Step 1: LogIn & Navigate: Log In to the GST Portal using your registered credentials. Navigate to Annual Return From the dashboard, go to Services → Returns → Annual Return.

Step 2: Select FY & Prepare Online: Select the Relevant Financial Year Under the "File Annual Return" section and click the “Prepare Online” option to begin the filing process. Make sure you read the instructions carefully before proceeding. 

Step 3: Fill in the Required Details: Go through each relevant table, (primarily Tables 4, 6, 7, 8, & 9) and enter your data. Tables with auto-populated fields (from CMP-08) will already have data and you need to review them for accuracy.

Step 4: Review, Download & Submit: Review your return before submission, download the GSTR-4 Summary PDF or the Excel version to cross-verify all entries against your books of accounts. Submit the Return by clicking "File GSTR-4".

Step 5: Authenticate the Filing: A warning message will appear for final confirmation. Select "Yes" and then choose one of the following authentication methods:

• File with DSC (Digital Signature Certificate), typically used by companies and LLPs
• File with EVC (Electronic Verification Code), typically used by proprietorships and partnerships

Step 6: Final Confirmation: Once successfully filed, your return status changes to "Filed" and you receive an ARN (Application Reference Number) along with an SMS/email confirmation on your registered mobile and email ID.

What is the Late Filing Fee for GSTR-4 Late Fee?

Ignoring the GSTR-4 due date can result in a monetary penalty. Here is the current late fee structure:

Note: Late fees are paid through the Electronic Cash Ledger and must be settled before the return can be filed.

Key Things Composition Taxpayers Must Know

1. No Input Tax Credit (ITC): Composition dealers cannot claim Input Tax Credit. You pay tax at a fixed flat rate on your turnover and cannot offset it against purchases made. This is a fundamental feature and limitation of the Composition Scheme.
2. GSTR-4 Cannot Be Revised: Once you file GSTR-4, it is final. There is no provision to revise it after the submission. This makes it critical to verify all figures carefully before hitting the File button.
3. GSTR-4 Is Mandatory Even for Nil Turnover: Even if your business was dormant for the full financial year, no sales, no purchases, you are still required to file a Nil GSTR-4. Skipping it attracts late fees and flags your registration for compliance issues.
4. CMP-08 Payments Reflect in GSTR-4: Your quarterly CMP-08 declarations act as the base for GSTR-4. Maintaining clean and timely CMP-08 filings throughout the year makes annual GSTR-4 preparation significantly easier.

Common Mistakes to Avoid While Filing GSTR-4

• Not reconciling CMP-08 data before filing GSTR-4. Discrepancies cause errors in auto-populated fields
• Missing the due date even by a day can trigger the late fee
• Incorrect classification of inward supplies, especially for reverse charge and unregistered dealer purchases
• Not reporting imported services, often overlooked, especially by service-based composition taxpayers
• Claiming ITC inadvertently, composition taxpayers are ineligible, any such claim invalidates the return

Why Timely GSTR-4 Filing Matters for Your Business?

For small businesses under the Composition Scheme, GSTR-4 is more than a regulatory checkbox. It is the document that:

• Proves your GST compliance to banks and investors during due diligence
• Establishes your financial credibility when applying for business loans
• Keeps your GSTIN active and non-compliance can trigger suspension of registration
• Avoids compounding penalties, a single delayed filing year leads to arrears that complicate future filings

The Composition Scheme was designed to simplify tax compliance for India's smallest businesses. Filing GSTR-4 annually, on time, is the core obligation that lets you continue enjoying that simplicity.

Conclusion

GSTR-4 is the single most important compliance filing for any taxpayer registered under the GST Composition Scheme. With the extended due date of 30th June (from FY 2024-25 onwards), revised and lower late fee caps, and a straightforward online filing process, the government has made this return more manageable than ever.

Whether you handle it yourself through the GST portal or work with a compliance partner, the key is to start early, reconcile your CMP-08 data, and file before the deadline.
