How to Reply to GST Show Cause Notice Under Section 73: Complete Guide

How to Reply to GST Show Cause Notice Under Section 73: Complete Guide

A Show Cause Notice (SCN) under Section 73 of the Central Goods and Services Tax (CGST) Act, 2017 is the formal start of an adjudication proceeding for non-fraud tax demands. You have 30 days from service to file your reply in Form DRC-06 on the GST portal. A structured, document-backed reply can eliminate the demand entirely, sharply reduce it, or protect your appeal record. Ignore the notice, and it becomes a confirmed demand order — followed by recovery proceedings — within a matter of weeks.

When Section 73 Applies — and When It Does Not

Section 73 covers four categories of tax shortfall:

1. Short-payment of output tax
2. Non-payment of output tax
3. Erroneous refund already received
4. Wrongly availed or utilised Input Tax Credit (ITC)

The decisive qualifier is intent. Section 73 applies only when no fraud, wilful misstatement, or suppression of facts is alleged. The moment the department alleges any of those, the notice must come under Section 74 — which carries a 100% penalty and a five-year limitation period instead of three years.

If your notice cites "Section 73(1)" on its face, read the allegations carefully. Officers occasionally invoke Section 73 but draft the SCN body in language that amounts to a suppression allegation. If this contradiction exists, raise it immediately as a preliminary objection — it can be fatal to the proceeding.

Limitation Period Under Section 73(10)

The proper officer must issue the SCN within three years from the due date of the annual return (GSTR-9) for the relevant financial year.

• FY 2022-23: GSTR-9 was due 31 December 2023 → SCN deadline 31 December 2026
• FY 2023-24: GSTR-9 was due 31 December 2024 → SCN deadline 31 December 2027
• FY 2024-25: GSTR-9 due date 31 December 2025 → SCN deadline 31 December 2028

Any SCN issued after its limitation date is void on its face. Cite Section 73(10) in your reply and, where available, relevant High Court rulings on limitation under the CGST Act.

Anatomy of a DRC-01: What to Read Before You Write a Single Word

The GST department issues the formal SCN in Form DRC-01. Before drafting any reply, extract and verify the following:

• Section invoked: Must read "73(1)" — not "74(1)"
• Period of demand: Which financial year and specific quarters
• Tax head-wise breakdown: CGST, SGST, IGST, and Cess shown separately with computation
• Relied-upon documents: The officer must list every document he relied on. Under principles of natural justice, you are entitled to copies of all of them — ask immediately if any are missing
• Date and time of personal hearing: Note it and diarise it. Missing a hearing without prior intimation is treated as a waiver
• Reply deadline: The 30-day clock runs from the date of service, which is the date the notice appears in your GST portal dashboard, not the date printed on the document
• Adjudicating officer and jurisdiction: Determines your appeal forum if needed

Also check whether a Form DRC-01A — the pre-notice statement under Rule 142(1A) — was served before the DRC-01. The procedure requires the officer to first offer you an opportunity to pay via DRC-01A. If that step was skipped entirely, you have a procedural ground in your favour that should be stated in the reply.

Deadlines, Extensions, and What Happens If You Miss the Window

The 30-day reply window opens on the date the DRC-01 appears in your portal under Services → User Services → View Notices and Orders.

Requesting an Extension

Section 75(5) permits the adjudicating officer to extend the time on a written request. File your extension request within the first seven days — not the twenty-eighth. State specific reasons: volume of records to reconstruct, the number of tax periods involved, and professional availability. Most officers grant 15 to 30 additional days for genuine requests. File the extension request through the same portal notice reply mechanism and retain the acknowledgement.

If You Miss the Deadline Entirely

The proper officer may pass an ex-parte order under Section 73(9) based solely on the material on his record. This is not final — you can appeal under Section 107 within three months of receiving the order — but you forfeit the opportunity to introduce documents at the adjudication stage. In practice, ex-parte orders are far harder and more expensive to undo than a well-prepared first reply. Do not let the deadline pass.

Step-by-Step: Filing Your Reply in Form DRC-06 on the GST Portal

Form DRC-06 is the only designated reply form for SCNs under Sections 73 and 74. The portal sequence is:

1. Log in to www.gst.gov.in using your GSTIN and credentials.
2. Navigate to Services → User Services → View Notices and Orders.
3. Locate the DRC-01 notice and click Reply.
4. In the DRC-06 screen, choose your response type: Dispute, Partial Acceptance, or Acceptance (full acceptance with payment).
5. Enter a concise three-to-four paragraph summary in the text box — the character limit is restrictive and unsuitable for detailed legal arguments.
6. Upload your detailed, signed reply as a PDF attachment along with all supporting documents (invoices, reconciliations, ledger extracts, case law). Portal upload limits are typically 10 MB per file; use multiple attachments if required.
7. Preview, submit, and save the Acknowledgement Reference Number (ARN) and a PDF copy of the submitted form.

Never submit your entire substantive reply in the text box alone. The portal is a filing mechanism; your arguments live in the signed PDF attachment. Courts and appellate authorities rely on the PDF, not the portal text field.

Drafting the Reply: Structure, Arguments, and Evidence That Work

A well-structured DRC-06 reply follows four parts in strict sequence.

Part 1 — Preliminary Objections

Open with grounds that could terminate the proceeding on procedure, before the merits are touched:

• Limitation: SCN issued after the three-year window from the GSTR-9 due date (cite Section 73(10) and the specific dates)
• Jurisdiction: Officer lacks territorial or subject-matter jurisdiction over your GSTIN
• Natural justice: Relied-upon documents were not supplied, or the time given is insufficient for a meaningful reply
• DRC-01A omitted: The pre-notice opportunity under Rule 142(1A) was not given
• Section misapplication: The body of the notice alleges suppression (a Section 74 standard) but invokes Section 73, creating an internal contradiction

Even one successful preliminary objection drops the entire notice without examining the merits.

Part 2 — Factual Narrative

Describe, in clear chronological terms, what happened in the business during the period under review. How were purchases recorded? How was ITC claimed? What reconciliations were performed between GSTR-2B and the purchase ledger? What figures appeared in GSTR-3B and why?

Every factual assertion must point to a specific annexure: "As shown in Annexure B (GSTR-3B for Q2 FY 2022-23) and Annexure C (purchase register for the same quarter)…". A narrative unsupported by documents is worthless.

Part 3 — Ground-by-Ground Rebuttal

Address every allegation individually. For each ground:

• State clearly whether you accept, partially accept, or deny the allegation
• Quote the exact provision cited by the officer and show factually why it does not apply — or where it does apply, what the correct quantum is
• Cite relevant case law: High Court rulings bind the adjudicating officer; Appellate Authority for Advance Rulings (AAAR) and Tribunal rulings carry persuasive weight
• Attach labelled, indexed annexures for every factual claim

A vague denial such as "the demand is bad in law" without elaboration is routinely noted as "considered and found to be without merit" in the adjudication order. Specific, document-backed rebuttals force the officer to engage with your position and, if he disagrees, to give reasons — which you can then challenge in appeal.

Part 4 — Prayer

Close with a clear and specific prayer:

• "Drop the proceedings in their entirety on the grounds stated above," or
• "Restrict the demand to the admitted sum of Rs. X, as computed in Annexure N," or
• "Pass a speaking order addressing each ground of reply so that the applicant's right of appeal is preserved."

Always ask for a speaking order, even when you expect to win. A non-speaking confirmation order is itself a ground of challenge at the appellate level.

Voluntary Payment Strategy: Section 73(5) vs Section 73(8)

The timing of any payment you make determines whether you pay a penalty at all.

The practical implication: If reconstruction confirms that a portion of the demand is genuinely correct, pay that admitted amount in Form DRC-03 within 30 days of the DRC-01, quote the SCN reference, and contest the balance in your DRC-06 reply. You eliminate all penalty on the admitted portion, close that portion of the proceeding, and fight only the genuinely disputed ground.

To file DRC-03 on the portal: Services → Payments → Create Challan → Reason: "Others" → Cause: "Section 73(5)/73(8)". Retain the payment acknowledgement and link it in your DRC-06 reply.

One caution: never pay before completing a line-by-line reconciliation. Many Section 73 demands shrink dramatically — or disappear entirely — on reconstruction.

Worked Example: Responding to an ITC Mismatch Demand of Rs. 8,40,000

Background: XYZ Components Pvt Ltd, a manufacturer registered in Maharashtra, receives a DRC-01 in November 2026 for FY 2022-23. The officer raises three separate ITC allegations.

Allegation 1 — Motor vehicle ITC (Rs. 4,80,000): The company claimed IGST credit on four passenger cars purchased for the field sales team. Section 17(5)(a) of the CGST Act blocks ITC on motor vehicles used for the transportation of persons (with exceptions not applicable here). On reconstruction, the company confirms this allegation is correct. Admitted: Rs. 4,80,000.

Allegation 2 — Construction services ITC (Rs. 2,40,000): The officer flags two civil contractor invoices. On reconstruction, the team finds that Rs. 1,20,000 relates to repair and re-tiling of the existing factory floor — which is repair of immovable property, not construction of new immovable property, and is not blocked under Section 17(5)(c). The remaining Rs. 1,20,000 relates to extension of the factory shed, which genuinely falls under Section 17(5)(c). Admitted: Rs. 1,20,000. Contested: Rs. 1,20,000 (with repair contract, invoice, and photographic evidence attached as annexures).

Allegation 3 — Rule 42 ITC reversal shortfall (Rs. 1,20,000): The officer computed the reversal using a statewide average exempt-supply ratio of 20%. The company's own GSTR-9 for FY 2022-23 shows actual exempt supply turnover of 10% of total turnover. Applying the correct ratio, the reversal requirement is Rs. 60,000, not Rs. 1,20,000. Admitted: Rs. 60,000. Contested: Rs. 60,000 (with GSTR-9 extract and Rule 42 recomputation as annexure).

Demand summary after reconstruction:

Interest on Rs. 6,60,000 at 18% per annum for 480 days (approximate period from original due date to payment): Rs. 6,60,000 × 18% ÷ 365 × 480 = Rs. 1,56,427

If paid within 30 days of DRC-01 under Section 73(8):

• Tax: Rs. 6,60,000
• Interest: Rs. 1,56,427
• Penalty: Nil
• Total cash outflow: Rs. 8,16,427

If the matter goes to adjudication and the order confirms Rs. 6,60,000:

• Tax: Rs. 6,60,000
• Interest: Rs. 1,56,427 (plus further accrual during adjudication)
• Penalty at 10%: Rs. 66,000
• Total cash outflow: Rs. 8,82,427 or more

Saving from timely Section 73(8) payment: Rs. 66,000 in penalty, plus interest accrual avoided during the adjudication period. The remaining Rs. 1,80,000 in contested tax is argued in the DRC-06 reply with documented support — and even if partially lost at adjudication, the penalty on that balance is a maximum of Rs. 18,000.

Pitfalls to Avoid

These are the errors that convert a manageable SCN into a confirmed demand and recovery proceeding.

1. Paying the full demand without reconciling first Department-computed demands are frequently overstated. Officers use GSTR-2A/2B discrepancies without accounting for supplier amendments, late invoice uploads, exempt supply corrections, or FY-end ITC claims. Reconcile line by line before accepting any number.

2. Filing a generic template reply A reply consisting of boilerplate phrases — "the demand is illegal and void ab initio," "natural justice has been violated" — with no documents and no case law is routinely noted as "considered but found to be without merit." The order confirms the full demand.

3. Ignoring the personal hearing Section 75(4) makes a personal hearing mandatory before any adverse order. Not attending does not make the demand disappear; it removes your last chance to present oral submissions and gauge the officer's concerns before he writes the order. Always attend, or send a properly briefed CA or advocate with a valid authorisation letter (Form GST PCT-05 where applicable).

4. Missing the DRC-01A stage If a DRC-01A was served before the DRC-01, the 30-day zero-penalty payment window opened at DRC-01A, not DRC-01. Taxpayers who ignore DRC-01A and wait for the formal SCN sometimes find that 30 days have passed before they even begin their reconstruction. Monitor your portal inbox for both forms regularly.

5. Using the cash ledger when Electronic Credit Ledger has balance If your Electronic Credit Ledger carries a sufficient CGST or IGST balance, use it to settle the admitted tax. Paying from cash while credit balance sits idle is unnecessary liquidity drain.

6. Not building the appeal record at adjudication Every argument you intend to raise at the First Appellate Authority (Section 107) or the GST Appellate Tribunal must be first raised in the DRC-06 reply. Introducing fresh grounds at the appellate stage without a prior record is routinely rejected. Your first reply is the foundation of your entire litigation strategy.

The Personal Hearing: How to Prepare and What to Say

A personal hearing under Section 75(4) is not a formality to be attended and forgotten. It is a quasi-judicial proceeding where the officer frames his final view.

Preparation (two to three days before the hearing):

• File a written follow-up submission summarising your three strongest arguments, with cross-references to the DRC-06 annexures. Officers appreciate conciseness.
• Prepare a one-page reconciliation table for each allegation: officer's figure on the left, your figure on the right, difference in the middle, document reference at the end.
• Brief your CA or advocate on every allegation, and on any procedural objections that remain live.

At the hearing:

• Confirm the officer has your DRC-06 reply and attachments on record.
• Walk through the reconciliation table rather than re-reading the reply verbatim.
• Ask explicitly: "Is there any further document the officer requires?" This creates a cooperation record.
• If the officer raises an allegation not contained in the SCN, object on the spot. An adjudication order cannot be passed on grounds not put to you in the notice — this is settled natural justice principle.
• Note the officer's name, designation, date, and time in your own file.

After the hearing (within three to five days):

• File a brief written submission confirming the hearing date, what was discussed, and any additional documents submitted. This protects your record if the matter proceeds to appeal and the hearing minutes are later disputed.

Key Takeaways

• Confirm the section: A DRC-01 citing Section 73 but alleging suppression in its body creates a contradiction — raise it immediately as a preliminary objection.
• The clock runs from portal service, not the notice date: Check your GST portal dashboard; the two dates can differ by several days, and every day counts toward your 30-day window.
• Reconstruct before you pay anything: Most Section 73 demands are overstated; line-by-line reconciliation frequently reduces the genuine tax due by 20-40%.
• Section 73(8) is your most powerful cost-saving tool: Pay the admitted amount in DRC-03 within 30 days of the DRC-01 and you owe zero penalty on that amount — a minimum 10% saving on whatever you pay.
• Structure your DRC-06 as a litigation document: Preliminary objections → factual narrative → ground-by-ground rebuttal → prayer, with signed, indexed PDF annexures.
• Every argument you plan to raise in appeal must first appear in your DRC-06: Appellate authorities do not readily admit fresh grounds that were never placed before the adjudicating officer.
• Attend every personal hearing and follow up in writing: The adjudication record, not the appellate order, is where GST disputes are won or lost.
