30 second summary | A GST DRC-01 Show Cause Notice is issued when tax authorities detect discrepancies such as underreported tax, excess ITC claims, or mismatches between GST returns. Responding accurately and on time is crucial to avoid penalties or legal action. The process involves verifying notice details, reconciling GST returns with books, deciding whether to accept or dispute the demand, and submitting a clear, point-by-point reply with supporting documents on the GST portal. Avoid common mistakes like missing deadlines or vague responses. Using GST software like TallyPrime helps ensure accurate reconciliation, proper documentation, and smooth compliance.

A GST DRC-01 Show Cause Notice is issued by the tax authorities when they identify discrepancies in your GST returns, such as underreported tax, excess input tax credit claims or mismatches between GSTR-1 and GSTR-3B. If you have received this notice, responding to it accurately and within the prescribed time will help you avoid penalties, interest or legal complications. 

In this blog, we will explain step by step process for drafting a professional reply for the GST DR-01 show cause notice. 

Step-by-step approach to respond to GST DRC-01

Follow the step-by-step approach to respond to GST DRC-01:

Verify the notice details

The first step is to examine the notice to understand the allegations carefully. Check the notice reference number, the tax period, the sections of the CGST Act cited (usually Section 73 or 74) and the amounts of tax claimed. Verify whether the notice matches your filing history and identify the specific discrepancies pointed out by the tax authorities.

Reconcile your GST returns and books

Once the notice details are verified, reconcile your GST returns with your books of accounts. Compare GSTR-1, GSTR-3B and GSTR-2A/2B data to identify mismatches, unclaimed and any short payment of tax. You can also use the GST software, which can simplify this process by automating reconciliation. 

Decide your response approach

After reconciliation, decide how you wish to respond to the notice. You can either:

  • Accept the liability fully and pay the demanded tax, interest and penalty
  • Partially accept the liability and contest the disputed amounts
  • Fully dispute the notice if you believe the allegations are incorrect.

The choice will determine the tone and content of your reply and the supporting documents required.

Draft a professional reply

Draft your reply in a structured, professional manner. Begin by referencing the notice number and tax period, followed by a point-by-point response to each allegation. Include documentary evidence such as invoices and statements generated through GST software

Also, ensure your reply is clear, factual and supported by legal provisions where necessary. Avoid ambiguous language, as it may lead to adverse conclusions.

File your reply on the GST portal

Log in to the GST portal and navigate to: Services > User Services > Notices/Orders. Select the relevant DRC-01 notice, upload your reply along with supporting documents and submit. Take note of the acknowledgement or reference number for future tracking. Timely submission ensures compliance and demonstrates proactive engagement with the tax authorities.

Prepare for personal hearing (if applicable)

If the authorities grant a personal hearing, prepare by reviewing your reply and all supporting evidence. Organise documents logically, anticipate possible questions and clarify your points concisely. A well-prepared hearing can significantly influence the outcome of the notice and reduce potential penalties.

Follow-up after submission

After submission, monitor updates on the GST portal. If you have admitted liability, pay the demanded tax promptly to avoid additional interest or penalties. In case of an adverse order, consider filing an appeal under the relevant provisions of the CGST Act. Maintaining proper records of all correspondence and actions taken is critical for future reference and compliance audits.

Common mistakes to avoid when responding to GST DRC-01 Notice

When responding to a GST DRC-01 Show Cause Notice, avoid the following mistakes:

  • Ignoring deadlines: Late responses can attract additional interest and penalties.
  • Submitting incomplete replies: Failing to attach required documents weakens your case.
  • Providing vague or generic responses: Point-by-point clarity is essential for effective communication with the authorities.
  • Admitting liability unintentionally: Be careful with language; do not concede amounts you intend to dispute.
  • Incorrect reconciliation: Mismatched figures between returns and books can create further complications. Using GST software helps minimise errors.
  • Applying wrong tax rates: Ensure correct rates using a GST rate finder to avoid further notices.
  • Not preparing for a personal hearing: Lack of preparation can affect outcomes if a hearing is called.

Conclusion

Navigating a GST DRC-01 Show Cause Notice can feel challenging, but with careful attention and the right approach, it becomes a manageable process. Staying organised, using GST software like TallyPrime and addressing the notice responsibly ensure your business remains compliant.
