A Show Cause Notice (SCN) under Section 73 of the CGST Act, 2017 is generally issued where tax has allegedly not been paid, has been short paid, has been erroneously refunded, or where Input Tax Credit has allegedly been wrongly availed or utilised — in situations that do not involve any allegation of fraud, wilful misstatement or suppression of facts.
Receiving such a notice does not automatically mean that the taxpayer is liable. The notice is a statutory opportunity to place facts, documentary evidence and legal submissions on record before the proper officer passes an adjudication order. How well that opportunity is used often determines the outcome of the entire proceeding.
Quick Summary
- Understand the allegation fully before replying.
- Never ignore a show cause notice.
- Collect complete documentary evidence.
- Reply point-wise to every allegation.
- Quote relevant GST provisions wherever applicable.
- Submit before the due date stated in the notice.
- Preserve the portal acknowledgement and full record.
Understanding Section 73
What the provision covers, and how it differs from proceedings alleging fraud or suppression.
The purpose of Section 73 is to enable the proper officer to determine tax that has escaped payment in ordinary, non-fraud situations — typically arising from mismatches, computational errors, differing interpretations, or credit availed in excess of what the records support. The officer must first put the taxpayer on notice, state the grounds, and give an opportunity to respond before determining any liability.
The key distinction is intent. Where the department alleges fraud, wilful misstatement or suppression of facts to evade tax, proceedings fall under the separate extended-period provision, which carries a longer limitation period and significantly higher penalty consequences. Section 73 proceedings, by contrast, proceed on the footing that no such intent is alleged — which is itself an important point to preserve in your reply, and to contest if the department later attempts to recharacterise the matter.
Responding within the time prescribed in the notice is critical. Where no reply is filed, the officer may adjudicate on the material already on record, and the taxpayer effectively forfeits the chance to explain the transactions. Equally critical is documentary evidence: in GST proceedings, assertions unsupported by invoices, returns, ledgers and reconciliations carry very little weight.

Timeline for Reply
An indicative working plan. Always follow the specific date stated in your notice, or any valid extension granted by the proper officer where permissible.
Note the date of service and the reply due date stated in the notice. Diarise it immediately.
Identify each allegation, the period involved, the amount demanded and the data the department has relied upon.
Gather invoices, returns, ledgers and bank records, and reconcile books with GSTR-1, GSTR-3B and GSTR-2B.
Prepare a point-wise reply with legal submissions and a numbered annexure index.
Upload the reply with annexures on the portal and download the acknowledgement.
Attend the hearing, place further clarifications on record and await the adjudication order.
Step-by-Step Reply Process
A disciplined sequence that produces a complete, evidence-backed submission.
Read the SCN Carefully
Go through the notice line by line and tabulate every particular it contains — GSTIN, tax period, reference number, date of issue, reply due date, each allegation, the provisions cited, the tax, interest and penalty proposed, and the documents relied upon by the department.
- GSTIN and legal name of the taxpayer
- Tax period covered by the notice
- Reference number (ARN / DIN) of the notice
- Date of issue and mode of service
- Due date for filing the reply
- Specific allegations raised
- Statutory provisions and rules cited
- Tax demanded, head-wise (CGST / SGST / IGST / Cess)
- Interest proposed
- Penalty proposed
- Documents and data relied upon by the department
Understand the Allegation
Identify the precise issue before drafting anything. An ITC mismatch reply is entirely different from a place-of-supply or classification reply, and a generic response to the wrong issue weakens your case.
- ITC mismatch
- GSTR-2B mismatch
- GSTR-1 vs GSTR-3B mismatch
- Excess ITC availed
- Short payment of tax
- Reverse charge (RCM) non-payment
- Classification issue
- Exemption dispute

- Wrong rate of tax applied

Final Thoughts
Responding to a show cause notice is not merely a procedural formality. It is the taxpayer's opportunity to present facts, supporting documents and legal submissions before the adjudicating authority, and it shapes the record on which every subsequent stage of the matter will be decided.
A well-organised, evidence-backed and timely reply can significantly strengthen the taxpayer's position. No outcome can be guaranteed, as every matter depends on its own facts, the applicable law, and the decision of the proper officer — but a disciplined reply ensures the case is decided on its merits rather than on an incomplete record.
