If a GST demand notice says you owe a tax shortfall that is wrong, do not ignore it and do not pay merely to make it disappear. First preserve the complete record, determine whether you have received a show-cause notice or a final order, test the department’s calculation against period-specific returns and source documents, and file a point-by-point response before the stated deadline. A final order follows a different route: you generally need to protect the appeal period and satisfy the applicable pre-deposit requirement.

The correct defense depends on the exact document, tax period, GSTIN, state or Union Territory, statutory section, service date and procedural history. A chartered accountant, GST practitioner or tax-dispute lawyer should review a live matter, particularly where fraud or suppression is alleged, limitation is disputed, or the tax, interest or penalty is substantial.

What to do in the first 24 hours

  1. Download and preserve everything. Save the full communication, every annexure, the portal version, the electronic service record and any email or physical-service proof. Do not rely only on a notification or a screenshot.
  2. Record the controlling details. Note the GSTIN, tax periods, date and mode of service, response date stated in the document, sections cited, amounts of tax, interest and penalty, and the officer or authority shown.
  3. Identify the procedural stage. Is it a show-cause notice proposing a demand, a final adjudication order, or a different mismatch or enforcement intimation? The remedy and filing form change with the stage.
  4. Calendar the deadline conservatively. Use the earliest date that could apply while you obtain advice. Portal outages, missing annexures or a later clarification should not be allowed to consume the response period.

A DRC-01 entry is the electronic summary of a show-cause notice. It does not replace reading the underlying notice and annexures. Rule 142 describes uploading the summary with the relevant demand notice and furnishing the taxpayer’s representation in DRC-06; the official Rules are available from the CBIC. The common-portal forms list also identifies DRC-06 among the GST forms at GST Forms Available on the Common Portal.

Notice or final order: why the distinction changes your next move

Document stage What it means Immediate route Evidence to preserve
Show-cause notice, often summarized in DRC-01 The department proposes a demand and invites your explanation before adjudication. Answer the allegations through the prescribed reply route, normally DRC-06 when the summary is uploaded in DRC-01. Notice, annexures, DRC-01 summary, service record, reply and acknowledgment.
Final demand or adjudication order The authority has decided liability, usually with tax, interest and possibly penalty. Examine appealability, the filing deadline, pre-deposit and FORM GST APL-01 requirements. Signed or portal order, communication proof, order number, computation and payment records.
Return-mismatch or other intimation A portal communication may belong to a process other than a section 73 or 74 demand. Identify its form and its own response mechanism before using DRC-06 or an appeal form. Exact form, discrepancy statement, response instructions and portal history.

Do not assume that every message labelled a “demand” is a section 73 or 74 proceeding. Read the heading, statutory provision, notice number and remedy instructions. If the document is incomplete, request the missing annexures promptly while preparing a protective response.

Check the legal section and the allegation

The section cited is not a formality. The CGST Act, 2017 distinguishes the grounds used for a non-fraud shortfall from those alleging intentional conduct.

Section 73: reasons other than fraud or wilful misstatement or suppression

Section 73 proceedings concern tax not paid or short paid, an erroneous refund, or input tax credit wrongly availed or utilised for reasons other than fraud, wilful misstatement or suppression of facts. A calculation, reporting or classification dispute may fall into this route, but the actual notice controls.

Section 74: fraud, wilful misstatement or suppression alleged

Section 74 proceedings allege fraud, wilful misstatement or suppression to evade tax. Treating such a notice as an ordinary arithmetic mismatch can undermine the response. Address the factual basis for the alleged intent, identify the documents that contradict it, and explain the reporting history, disclosures and cooperation. Do not simply repeat the officer’s characterization or make an unqualified admission without professional advice.

Section 74A and other current provisions

The GST Portal’s appeal FAQ now lists section 74A demand orders among appeal categories, but the applicable section, limitation rules and treatment of the relevant tax period must be checked against the current law and the notice. Do not infer a deadline from a section number alone.

Reconcile the department’s arithmetic to your records

Build a period-by-period schedule before writing conclusions. Every figure in the notice should be traceable to a return, invoice, ledger entry or payment proof, and every correction in your response should point back to an indexed document.

Test Records to compare Errors to look for
Output-tax calculation GSTR returns and amendments, sales register, tax invoices, debit and credit notes, contracts and rate notifications used for the transaction. Wrong tax rate, duplicate invoice, missed credit note, a cancelled document counted as taxable, or a transaction assigned to the wrong period.
Input tax credit Purchase register, supplier invoices, credit notes, electronic credit ledger, return workings and any reconciliation already supplied. Credit note or reversal counted twice, an amendment omitted, a transaction attributed to another GSTIN, or a reporting difference mistaken for ineligible credit.
Tax already paid Electronic cash, credit and liability ledgers, challans, bank statements and return payment details. The same liability counted twice, a payment posted to another period, an incorrect minor head, or a challan not matched to the GSTIN.
Interest and penalty Payment dates, return filing dates, order computation and the statutory basis stated in the notice. Interest calculated on an amount already paid, an incorrect period, or a penalty provision that does not match the alleged conduct and stage.

Keep the original data unchanged and work from a copy. Use one row per tax period and, where practical, one row per allegation or invoice group. A useful schedule has columns for the department’s figure, your corrected figure, variance, reason, document reference and whether the amount is admitted or disputed.

Prepare a point-by-point reply

A strong response lets the officer match each allegation with a fact, calculation and document without searching through an unstructured bundle.

  1. Start with identification. State the GSTIN, legal name, notice number, tax period, date received and the section cited. Mention if an annexure or calculation is missing.
  2. Give a short position on each allegation. Mark it admitted, partly admitted or disputed. Do not use a blanket denial when one component is correct.
  3. Show the corrected computation. Set out the department amount, your amount, the difference and the mathematical basis. Explain the treatment of tax, interest, penalty and any amount already paid.
  4. Explain the factual reason. For example, identify the credit note number, amended return, payment challan, separate GSTIN or classification document that changes the result.
  5. Address the legal basis. Explain why the cited provision does or does not apply to the facts. Where fraud, wilful misstatement or suppression is alleged, respond to the specific conduct and evidence rather than only the arithmetic.
  6. Use an indexed attachment set. Number each attachment and cross-reference it in the paragraph and reconciliation row where it is used.
  7. State the relief requested. Ask that the incorrect portion be dropped, the computation be corrected, and any personal hearing or clarification permitted by the applicable procedure be granted.

Write in neutral, precise language. Avoid destroying credibility with unsupported accusations, irrelevant history or a copied template that does not answer the notice’s actual allegations.

File the response and preserve proof

  1. Open the notice in the GST portal and confirm the response option and due date shown for that communication.
  2. Prepare the reply in the required format and use FORM GST DRC-06 where the notice summary has been uploaded in DRC-01, as described in Rule 142.
  3. Upload the signed reply and legible attachments within the permitted file-size and format limits. If the portal rejects a file, retain the error screen and use the official support or permitted alternate filing channel without abandoning the deadline.
  4. Submit and save the acknowledgment, ARN or reference number, timestamp, uploaded files and a complete PDF of the final response.
  5. Keep a contemporaneous service log recording every submission, call, email, hearing notice and portal event.

A submission that cannot later be proved is difficult to rely on. Store the acknowledgment and attachments in more than one secure location, with file names that include the notice number and date.

Separate admitted amounts from disputed amounts

Do not pay or concede the entire demand simply because part of it may be correct. Create separate lines for admitted tax, disputed tax, interest and penalty. If you consider voluntary payment or a statutory reduced-penalty route, have an adviser confirm the applicable section, timing, interest calculation, form and legal effect. The correct payment route depends on the facts and procedural stage; a payment can affect the amount in dispute, available relief and appeal strategy.

Where only a portion is accepted, say exactly which rows are admitted and which are challenged. Reconcile any payment to the correct GSTIN, tax period and ledger head, then attach the challan and ledger evidence.

If a final demand order has already been issued

Move immediately to appeal analysis. The GST Portal FAQ on Appeal against Demand Order gives a general period of three months from communication of the decision or order. It also states that delay may be condoned for up to one further month for sufficient cause. Those are general portal instructions, not a substitute for checking the statute, the order, service record and any special rule applicable to your case.

Appeal preparation checklist

  • Obtain the complete order, computation, annexures and proof of communication.
  • Identify every finding challenged and map it to the evidence already filed or newly available.
  • Calculate the disputed tax carefully; do not treat interest or penalty as the same figure as disputed tax for pre-deposit purposes.
  • Confirm the applicable pre-deposit. The portal FAQ describes a 10% pre-deposit of disputed tax before filing, but verify the amount and any statutory cap or special rule for the particular order.
  • Prepare the appeal through FORM GST APL-01 if that is the prescribed portal route, attach the order and grounds, and save the acknowledgment.
  • Have counsel review whether a stay, rectification, additional evidence request or other remedy is needed alongside the appeal.

The appealable-demand categories shown in the FAQ include assessment orders under sections 73, 74 and 74A. A late filing, wrong order number or insufficient pre-deposit can create a separate procedural problem, so obtain case-specific advice before submission.

Records checklist

  • Full notice or order, every annexure, DRC-01 summary and portal service record.
  • GSTIN, tax periods, cited sections and the officer’s computation.
  • Filed returns and amendments, invoices, credit and debit notes, contracts and classification material.
  • Books, sales and purchase registers, reconciliation workpapers and electronic cash, credit and liability ledgers.
  • Challans, bank proof and evidence of any earlier tax deposit or reversal.
  • Earlier replies, audit or investigation correspondence, hearing notices and minutes.
  • A row-by-row schedule linking each department figure to your corrected figure and document references.
  • Final submitted response, attachments, acknowledgment, ARN and portal screenshots or downloaded receipts.

Special issues that need separate treatment

Limitation

Do not use a generic “the notice is time-barred” paragraph. The relevant period depends on the tax year, section, statutory amendments, date and mode of service, extensions, and the procedural record. The available material does not establish one deadline for a hypothetical notice. If limitation is a defense, have an adviser calculate it from the exact tax period and documents.

Input-tax-credit amendments

CBIC Circular 237/31/2024-GST addresses specified retrospective amendments to input-tax-credit provisions and explains how authorities should consider cases at different procedural stages. Read the circular only if the demand concerns the ITC issue it covers; it is not a universal answer to every ITC dispute.

Missing or inconsistent portal data

If the portal summary differs from the signed notice, or an annexure cannot be opened, preserve both versions, describe the inconsistency in the reply and request the complete relied-upon material. Do not silently choose the smaller figure.

Allegations of fraud or suppression

These allegations can change the statutory route, penalty exposure and evidentiary focus. Gather contemporaneous books, disclosures, correspondence, correction history and explanations for any reporting difference. Professional review is especially important before making admissions.

Choose the next step by risk, not just by amount

Situation Priority Practical next step
Notice, clear arithmetic error, complete records Meet the reply deadline and make the computation easy to verify. File an indexed DRC-06 response with the reconciliation and payment proof.
Notice, mixed admitted and disputed items Prevent an avoidable concession while isolating the accepted amount. Use separate schedules and obtain advice on any voluntary payment or reduced-penalty option.
Notice alleging fraud or suppression Address intent allegations and statutory consequences, not only figures. Have a qualified adviser review the draft before filing.
Final order, deadline approaching Preserve appellate rights first. Confirm communication date, disputed-tax calculation, pre-deposit and APL-01 filing steps.
Incomplete notice or portal mismatch Create a service and evidence trail. Request missing material, document the defect and file a protective response within time.

Common mistakes and how to recover

  • Ignoring a DRC-01 because the figure looks obviously wrong: file a documented response; an unchallenged allegation can become harder to correct later.
  • Replying only with a spreadsheet: explain the legal and factual reason for every adjustment and cite the supporting document.
  • Using the wrong form: verify whether the communication is a DRC-01 notice, DRC-06 reply opportunity, final order or another mismatch process.
  • Missing the appeal date: calculate from communication of the order, preserve service proof and seek advice immediately if delay has occurred.
  • Uploading unreadable or incomplete attachments: check each file after upload and retain the final submitted copy.
  • Assuming a payment ends the dispute: confirm whether payment admits liability, affects penalty, or changes the amount that can be appealed.

When to obtain professional help

Get a chartered accountant, GST practitioner or tax lawyer involved before filing when the notice alleges fraud, wilful misstatement or suppression; the amount is material; several GSTINs or states are involved; ITC eligibility is disputed; limitation may apply; records are incomplete; a hearing has been scheduled; or a final order has already been passed. Give the adviser the notice, service proof, reconciliation, ledgers, returns, prior correspondence and your draft chronology. Early review is usually more useful than asking someone to reconstruct the case after the deadline.

Your practical objective is to create a verifiable record: the correct procedural stage, a defensible period-by-period calculation, a focused answer to every allegation, proof of filing and a protected appeal option if an order follows.
