The Goods and Services Tax has centralized and streamlined indirect taxation in India by employing a broad-based system spanning goods and services. Under GST, certain small taxpayers shall opt for the Composition Scheme to pay taxes at minimal rates without input tax credits by filing quarterly returns in Form GSTR-4.

However, the seemingly straightforward GSTR-4 return also carries scope for inadvertent errors due to its unfamiliarity with frequently amended GST provisions. Even minor discrepancies could expose taxpayers to scrutiny, audits, penalties, and even disqualification from the composition scheme, which erodes working capital with a higher tax burden.

Therefore, composition suppliers must gear up with robust, fool-proof practices to avoid common mistakes in GSTR-4 filing. Instead of an afterthought, compliance should become integral to business management for sustainable success.

Identifying And Preventing Errors In GSTR-4 Submissions:

GSTR-4 is an annual return that composition taxpayers should file. These taxpayers will ensure accuracy in their GSTR-4 filings. If any discrepancies or errors are not detected and rectified, it could lead to different tax compliance issues for the business. 

One of the pivotal problems is that the tax authorities may impose a late fee for delayed filing of the annual return. According to the CGST Act, the late charge will be Rs. 100 each day, subject to a highest of Rs. 5,000.

Another penalty that could be imposed is interest liability on the short payment of tax. If supplies have been underreported in GSTR-4 due to errors, it would lead to a short payment of tax. In such cases, interest at the rate of 18% per annum will be levied on the short-paid amount from the due date of payment until the date of actual payment. The tax department may also issue a show cause notice seeking an explanation for any discrepancies observed in the annual return. It could then lead to actions like audits or investigations being initiated against the business.

In the worst case, unreported or incorrectly reported supplies may be considered concealed supplies. It might result in a tax demand being boosted, along with interest and penalties. Penalties of up to Rs. 25,000 can be imposed under the CGST Act for furnishing incorrect details in the annual return. Additionally, any input tax credit claimed might get rejected or blocked until the errors are rectified. Hence, it is pivotal for composition taxpayers to thoroughly review their GSTR-4 filings and rectify any errors at the earliest.

Filing GSTR-4 can seem deceptively simple for composition taxpayers. However, even minor errors can lead to heavy penalties or the disallowance of the chosen composition scheme. Some frequent mistakes include:

Inaccurate Turnover Reporting:

  • Failing to include deemed supply transactions
  • Excluding non-GST supplies from aggregate turnover
  • Errors in tallying turnover across GSTR-4 tables

Strategies To Prevent Errors:

  • Maintain consolidated records of all supplies—non-GST, GST, deemed
  • Carefully extract values from books of accounts to report in GSTR-4
  • Reconcile turnover values entered across various tables

Wrong Tax Liability:

  • Applying incorrect tax rate
  • Incorrect classification of goods and services
  • Omitting RCM liability on ineligible ITC expenses


  • Refer to rate notifications to detect the correct tax rate
  • Map business operations to HSN codes for proper classification
  • Account for RCM dues and report in GSTR-4

Incorrect ITC claims:

  • Availing credit of GST paid under forward charge
  • Carrying forward past period’s ineligible ITC to the current tax period

Steps To Avoid Errors:

  • Review ITC eligibility before making any claim
  • Ensure ITC claimed pertains to supplies accounted in the given tax period
  • Detect and omit ineligible ITC, if any, from the reported amount
Error Corrective Action
Claiming ITC of GST paid under forward charge Note that only RCM credit on ineligible expenses can be claimed
Including ITC of previous periods Report only eligible ITC for the relevant tax period
Failing to reverse ineligible ITC Detect and omit credits like motor vehicle tax

Regulatory Guidelines For Error-Free GSTR-4 Filing:

Certain legal guidelines prescribed by Goods and Services Tax laws regulate the procedures and criteria for error-free GSTR-4 filing:

  • Reporting threshold: Aggregate turnover over Rs. 1.5 crore disqualifies composite scheme opting
  • Quarterly periodicity: GSTR-4 is to be filed quarterly within the 18th of next month
  • HSN reporting: Mandatory for taxpayers with greater Rs. 5 crore turnover
  • ITC eligibility: Only input tax credit under RCM allowed, not normal GST
  • Compliance ratings: High differences inGSTR-1, and GSTR-4 could affect ratings
  • Revisions mechanism: Errors can be corrected in the subsequent tax period

Adhering to these vital regulatory guidelines while filing returns enhances overall compliance and reduces errors and related consequences.
