Your Complete Guide to GSTR 4: Due Dates, Formats, Filing Process, Penalities, and FAQs.       

GSTR-4 is an annual return that must be filed by taxpayers who have opted for the GST Composition Scheme. This scheme was introduced under the Goods and Services Tax (GST) to simplify the tax filing process for small businesses. Instead of filing monthly returns like regular taxpayers, businesses under the Composition Scheme can file a single return annually in the form of GSTR-4. This eases compliance and reduces the administrative burden, making it particularly beneficial for small and medium enterprises (SMEs), manufacturers, traders, and restaurant owners.

Under the Composition Scheme, taxpayers pay tax at a fixed rate based on their turnover, without the need to maintain detailed records of every transaction. However, while the tax payments are made quarterly through the CMP-08 form, GSTR-4 consolidates the taxpayer’s annual financial data, covering details of inward and outward supplies, tax paid, and any changes from previous returns. Filing GSTR-4 on time ensures businesses remain compliant with GST regulations, avoid penalties, and maintain smooth business operations.

In this guide, we’ll walk you through everything you need to know about GSTR-4, including eligibility criteria, filing deadlines, penalties, and the step-by-step process of filing the return.

What is GSTR-4?

GSTR-4 is an annual GST return specifically designed for taxpayers who have opted for the Composition Scheme. This scheme offers simplified tax compliance for small businesses by allowing them to file just one annual return instead of multiple monthly returns required by regular taxpayers. The key objective of GSTR-4 is to consolidate the taxpayer’s annual financial data, ensuring that all inward and outward supplies, taxes paid, and any relevant adjustments are reported in a single form.

The Composition Scheme is aimed at reducing the compliance burden for small businesses, with a lower tax rate and less frequent filings. However, it’s important to note that taxpayers under this scheme cannot claim Input Tax Credit (ITC), and they must issue a “Bill of Supply” instead of a tax invoice since they are not allowed to charge GST from their customers.

GSTR-4 provides a complete picture of a business’s transactions for the financial year, including purchases, sales, and tax liabilities. By filing this return, businesses ensure that they meet the legal requirements of GST and avoid penalties associated with late or non-filing.

The return must be filed by April 30th of the following financial year, and it consolidates the tax payments made quarterly through the CMP-08 form. It covers various sections, such as turnover details, inward and outward supplies, tax paid, and amendments to previous returns, making it a comprehensive document for businesses under the Composition Scheme.

Who Should File GSTR-4?

GSTR-4 must be filed by all taxpayers registered under the GST Composition Scheme. This scheme is designed for small businesses, manufacturers, traders, and certain service providers who want to reduce their compliance burden. It allows them to pay tax at a fixed rate of turnover instead of the normal GST rates applicable to regular taxpayers.

Eligibility for Filing GSTR-4:

  1. Turnover Limit: Businesses with an annual aggregate turnover of up to ₹1.5 crores can opt for the Composition Scheme in most states. For service providers, the turnover limit is ₹50 lakhs.
  2. Types of Businesses: Small businesses engaged in the supply of goods, manufacturers (except those producing items like tobacco, ice cream, etc.), and restaurants (excluding those serving alcohol) are eligible.
  3. Intra-state Suppliers Only: Composition dealers can only make intra-state supplies, meaning their goods and services are restricted to within the state. Interstate suppliers are not eligible for the scheme.
  4. Certain Exclusions: Businesses engaged in making supplies through e-commerce platforms or providing non-restaurant services cannot opt for the Composition Scheme.

Who Shouldn’t File GSTR-4?

Not every GST taxpayer qualifies for the Composition Scheme, and hence, not everyone needs to file GSTR-4. The following categories are exempt:

Non-resident taxable persons.
Casual taxable persons.
TCS/TDS deductors.
Input service distributors.
Businesses providing Online Information Database Access and Retrieval (OIDAR) services.

Nil GSTR-4 Filing: If a composition dealer has not conducted any business during the financial year and has no inward or outward supplies, they are still required to file a Nil GSTR-4 return. This ensures that the taxpayer complies even if there are no transactions during the year.

By ensuring only eligible taxpayers under the Composition Scheme file GSTR-4, the system streamlines compliance and reduces the complexities involved in GST filing for small businesses.

What is the Due Date for Filing GSTR-4?

The due date for filing GSTR-4 is April 30th of the financial year following the one for which the return is being filed. This means that for any financial year, taxpayers under the Composition Scheme are required to file their GSTR-4 by April 30th of the next financial year.

While the tax payments for composition taxpayers are made quarterly through CMP-08, GSTR-4 is a consolidated annual return that summarizes the entire year’s transactions, including inward and outward supplies, tax liabilities, and adjustments from previous filings.

GSTR-4 Filing Extensions and Compliance Reminders: The GST Council may extend the due dates under specific circumstances, such as during the COVID-19 pandemic when certain deadlines were extended to provide relief to businesses. However, taxpayers are advised to ensure timely filing to avoid late fees and penalties.

Consequences of Missing the GSTR-4 Due Date: Failing to file GSTR-4 by the due date can lead to financial penalties:

  • Late Fee for Regular Returns: A late fee of ₹200 per day (₹100 CGST + ₹100 SGST) is applicable, subject to a maximum of ₹5,000.
  • Late Fee for Nil Returns: For Nil returns, the late fee is reduced to ₹20 per day (₹10 CGST + ₹10 SGST), subject to a maximum of ₹500.
  • Interest: In addition to late fees, an interest of 18% per annum is charged on any outstanding tax liability, calculated from the due date until the actual date of payment.

It’s crucial to file the return on time not just to avoid penalties but also to maintain compliance with GST regulations. Failure to file GSTR-4 could also impact a taxpayer’s ability to file subsequent returns and cause complications in the business’s financial records.

What is the Format of GSTR-4?

Prerequisites for Filing GSTR-4

Before you can proceed with filing GSTR-4, there are certain prerequisites that must be met to ensure a smooth filing process. Ensuring that all conditions are fulfilled beforehand can help avoid errors, delays, or potential penalties.

Here are the key prerequisites for filing GSTR-4:

  1. Opting for the Composition Scheme:

The taxpayer must have opted for the GST Composition Scheme. This scheme is available to small businesses with a turnover of up to ₹1.5 crore (or ₹75 lakhs in special category states), and for service providers with a turnover limit of ₹50 lakhs.

  1. Filing of CMP-08 for All Quarters:

Composition taxpayers are required to file CMP-08 quarterly, which is a statement-cum-challan used to declare their self-assessed tax liability and make tax payments for the quarter. GSTR-4 consolidates these quarterly filings, so all CMP-08 forms for the financial year must be filed before submitting GSTR-4.

  1. Maintaining Proper Records:

Accurate and detailed records of inward and outward supplies are necessary to file GSTR-4. This includes purchases from registered and unregistered suppliers, sales made during the financial year, and any reverse charge transactions.

Composition taxpayers must maintain records of their sales and purchases to ensure that the details in GSTR-4 are accurate and complete.

  1. Payment of All Outstanding Tax Liabilities:

Any outstanding tax, interest, or late fees should be paid before filing GSTR-4. If the taxpayer has not made the necessary payments through CMP-08, they need to clear all dues before proceeding with the annual filing.

If there’s insufficient balance in the electronic cash ledger, the taxpayer will need to create a challan to make the payment.

  1. Aggregate Turnover for the Previous Financial Year:

The taxpayer must have the exact details of their aggregate turnover for the previous financial year ready, as this information needs to be entered in GSTR-4. The turnover details will affect the overall tax calculation, so they must be precise.

  1. GST Portal Login Credentials:

Ensure that you have the necessary login credentials to access the GST portal. Without these, you cannot proceed with the online filing process.

  1. Digital Signature Certificate (DSC) or Electronic Verification Code (EVC):

For businesses or individuals required to file returns with DSC or EVC, ensure that these are active and ready to use. The return cannot be submitted without proper verification.

  1. TDS/TCS Credit Details (if applicable):

Suppose the taxpayer has received any Tax Deducted at Source (TDS) or Tax Collected at Source (TCS) credits during the financial year. In that case, they should be aware of the details, as this information will be auto-populated in GSTR-4.

By ensuring these prerequisites are met, taxpayers can avoid complications and ensure that their GSTR-4 filing is accurate, complete, and timely. This will help avoid penalties and maintain compliance with GST regulations.

Common Errors and Corrections in GSTR-4

While filing GSTR-4, it’s important to ensure accuracy in the information provided, as errors or omissions can lead to non-compliance, penalties, and complications in future filings. Here are some common errors that taxpayers make when filing GSTR-4 and how to correct them:

1. Incorrect Turnover Details

  • Common Error: Taxpayers often make mistakes when reporting the aggregate turnover for the previous financial year. Misreporting turnover can lead to an incorrect tax liability calculation.
  • Correction: Double-check your records to ensure the aggregate turnover matches the sales recorded for the financial year. Use accurate sales data and verify the information before filing.

2. Missing Inward or Outward Supply Details

  • Common Error: Not reporting all inward and outward supplies accurately, especially those subject to reverse charge, can result in discrepancies. Some taxpayers may forget to include supplies from unregistered suppliers or import of services.
  • Correction: Review your purchase and sales records thoroughly to ensure that all supplies are captured. Specifically, make sure to report inward supplies from registered suppliers (with and without reverse charge) and from unregistered suppliers.

3. Incorrect Application of Tax Rates

  • Common Error: Taxpayers sometimes apply the wrong tax rates when reporting outward supplies or reverse charge inward supplies.
  • Correction: Cross-check the applicable tax rates (CGST, SGST, IGST, and Cess) based on the nature of the supplies. Ensure that you have applied the correct tax rates as per the latest GST regulations.

4. Non-reconciliation of CMP-08 Data

  • Common Error: Data reported in GSTR-4 should match the details declared in the quarterly CMP-08 filings. If there is a mismatch, it could lead to discrepancies in the overall tax liability.
  • Correction: Before filing GSTR-4, review the CMP-08 statements for each quarter and ensure that the totals reconcile with the data entered in GSTR-4.

5. Failure to Pay Outstanding Tax Liabilities

  • Common Error: Some taxpayers forget to pay any outstanding tax liabilities, interest, or late fees before filing, which can result in an incomplete submission.
  • Correction: Check your electronic cash ledger to ensure that you have sufficient balance to pay any outstanding taxes. If required, generate a challan and pay the dues before submitting the return.

6. Incorrect Information in Auto-Populated Fields

  • Common Error: The GSTR-4 form auto-populates certain fields, such as TDS/TCS credit received and CMP-08 payments. Occasionally, these fields may contain errors if previous filings were incorrect.
  • Correction: Review all auto-populated fields carefully. If any discrepancies are found, ensure that they are addressed before proceeding with the filing. Amendments may need to be made to previous returns to correct the auto-populated data.

7. Misreporting of Amendments

  • Common Error: Taxpayers sometimes forget to report amendments made to previous inward or outward supplies, leading to discrepancies between filings.
  • Correction: Use the Amendments section in GSTR-4 to correct any errors from previous filings. Ensure that all adjustments are accurately recorded in the relevant tables.

8. Filing GSTR-4 Without Reviewing

  • Common Error: Submitting GSTR-4 without previewing and reviewing the form for errors can lead to mistakes being filed with the GST authorities.
  • Correction: Always preview the form by downloading it in PDF or Excel format before filing. Carefully review the details for accuracy, especially tax liabilities, supply details, and payments.

Can GSTR-4 Be Revised?

Unfortunately, GSTR-4 cannot be revised once it has been submitted. This makes it crucial to ensure that all the information entered is accurate before final submission. If any errors are discovered after filing, they must be corrected in the next financial year’s return.

How to Correct Errors After Filing GSTR-4?

If you’ve made an error in your GSTR-4 filing that cannot be corrected immediately, you can make adjustments or amendments in the following financial year’s GSTR-4 return. Here’s how:

  • Use the Amendment Tables in the subsequent GSTR-4 filing to rectify any errors made in the previous return.
  • Ensure that you maintain proper documentation and records to support any amendments made.

By staying vigilant and taking care of these common issues, composition taxpayers can avoid errors in their GSTR-4 filing, ensuring a smooth and compliant GST filing experience.

Late Fees and Penalties for Non-Filing of GSTR-4

Filing GSTR-4 on time is crucial for businesses under the Composition Scheme to avoid financial penalties and maintain compliance with GST regulations. Failing to file by the due date can result in late fees, interest, and restrictions on future filings. Here’s an overview of the penalties and consequences for late or non-filing of GSTR-4:

1. Late Fees for Non-Filing or Late Filing of GSTR-4

When GSTR-4 is not filed on time, the taxpayer becomes liable to pay a late fee. The late fee is calculated on a daily basis until the return is filed, subject to a maximum limit.

  • For Regular Returns:
    • Late Fee: ₹200 per day (₹100 CGST + ₹100 SGST), up to a maximum of ₹5,000.
    • This penalty applies for each day the return remains unfiled after the due date (April 30th of the following financial year).
  • For Nil Returns:
    • Late Fee: ₹20 per day (₹10 CGST + ₹10 SGST), subject to a maximum of ₹500.
    • This reduced penalty applies if the taxpayer has no business transactions during the financial year and is filing a Nil return.

It’s important to note that these penalties accumulate daily until the return is filed, but they are capped at the maximum limits mentioned above.

2. Interest on Outstanding Tax Liability

In addition to the late fee, taxpayers who have any outstanding tax liability at the time of filing will be charged interest on the unpaid amount.

  • Interest Rate: 18% per annum on the unpaid tax amount.
  • Interest Calculation: The interest is calculated from the due date (April 30th) until the date the outstanding taxes are paid.

For example, if a taxpayer has an outstanding tax liability of ₹10,000 and delays payment for 30 days, the interest payable will be ₹10,000 x 18% / 365 x 30 days = ₹147.95.

3. Impact of Non-Filing of GSTR-4

Failing to file GSTR-4 on time can have significant consequences beyond financial penalties:

  • Inability to File Future Returns: If GSTR-4 is not filed, the taxpayer may be restricted from filing future GST returns, including the next financial year’s returns. This can lead to further complications with compliance.
  • Restrictions on E-way Bill Generation: Non-filing of GSTR-4 may also block the generation of e-way bills, which are required for the transport of goods in certain cases. This can disrupt business operations, especially for taxpayers involved in the movement of goods.
  • Loss of GST Composition Scheme Eligibility: Continuous failure to comply with GSTR-4 filing requirements could result in the taxpayer being ineligible for the Composition Scheme in the future, forcing them to switch to regular GST filings, which are more complex and frequent.

Timely filing of GSTR-4 ensures that composition taxpayers avoid these penalties, maintain compliance, and keep their business operations running smoothly.
