GST notice DRC-01 / ASMT-10 — How to reply professionally

GST Notice DRC-01 / ASMT-10 — How to Reply Professionally

Receiving a GST notice can be stressful, especially when the notice points out differences in turnover, ITC, tax payment, GSTR-1, GSTR-3B or other GST records.

However, receiving a notice does not automatically mean that tax demand has been confirmed.

The most important thing is to understand the type of notice, identify the discrepancy, reconcile the records and submit a clear, evidence-based reply within the prescribed time.

Many taxpayers and business owners ask:

“What is ASMT-10?”

“What is DRC-01?”

“Are ASMT-10 and DRC-01 the same?”

“How should I reply to a GST notice?”

“What documents should I attach?”

“Should I accept the demand or dispute it?”

Let’s break it down. 🚀

📌 What is GST ASMT-10?

FORM GST ASMT-10 is a notice issued when the GST officer identifies discrepancies during scrutiny of a taxpayer’s GST return.

Under the GST rules, the proper officer may scrutinize the return with reference to information available with the department and issue ASMT-10 where discrepancies are identified. The notice communicates the discrepancy and seeks an explanation from the taxpayer.

Common issues mentioned in ASMT-10 may include:

📊 GSTR-1 vs GSTR-3B mismatch

📦 GSTR-1 vs e-way bill differences

💳 GSTR-3B vs GSTR-2B/2A differences

💰 Excess ITC

📈 Turnover mismatch

🧾 Tax liability mismatch

📋 Incorrect reporting

💵 Short payment of tax

📑 Other return-related discrepancies

📌 What is GST DRC-01?

FORM GST DRC-01 is generally associated with a demand/show-cause notice framework where the department communicates the tax, interest and penalty proposed in proceedings.

It is important not to treat every DRC-01 as equivalent to an ASMT-10.

ASMT-10 is primarily a scrutiny discrepancy notice.

DRC-01 is generally the electronic summary of a show-cause notice/demand proceeding under the applicable GST provisions.

Therefore:

ASMT-10 → Scrutiny of return / discrepancy

DRC-01 → Summary of a show-cause notice/demand proceeding

📊 ASMT-10 vs DRC-01

Particulars ASMT-10 DRC-01

Purpose Intimation of return discrepancy Summary of SCN/demand proceedings

Nature Scrutiny Demand/SCN proceeding

Main focus Explanation of discrepancy Proposed tax, interest and penalty

Taxpayer response ASMT-11 Reply to SCN through applicable GST process

Payment Can be made if discrepancy is accepted Payment can be made where liability is accepted

Result ASMT-12 may be issued if explanation is accepted Order may follow if proceedings continue

The GST rules specifically provide that a taxpayer receiving ASMT-10 can either accept the discrepancy and pay the applicable amount or furnish an explanation in FORM GST ASMT-11.

🎯 Why Do Businesses Receive GST Notices?

GST notices may arise because the department’s data does not match the taxpayer’s return information.

For example:

GSTR-1 Turnover → ₹50 lakh

GSTR-3B Turnover → ₹45 lakh

Difference → ₹5 lakh

This does not automatically mean that ₹5 lakh of sales were concealed.

The difference could arise because of:

✔ Credit notes

✔ Advances

✔ Amendments

✔ Timing differences

✔ B2C/B2B reporting differences

✔ Wrong reporting period

✔ Export transactions

✔ Exempt supplies

✔ Nil-rated supplies

✔ Data-entry errors

📊 Common GST Notice Issues

Some of the most common discrepancies include:

1️⃣ GSTR-1 vs GSTR-3B

2️⃣ GSTR-3B vs GSTR-2B

3️⃣ ITC claimed vs eligible ITC

4️⃣ E-way bill vs GST returns

5️⃣ GSTR-9 vs GSTR-1/3B

6️⃣ Turnover vs books of accounts

7️⃣ Tax liability mismatch

8️⃣ RCM liability

9️⃣ Interest on delayed payment

🔟 Wrong GST rate

1️⃣1️⃣ Non-filing or delayed filing

1️⃣2️⃣ ITC from inactive/cancelled suppliers

📌 First Step — Do Not Panic

The first mistake businesses make after receiving a GST notice is immediately accepting the department’s calculation.

Do not do this.

First understand:

📄 Notice number

📅 Notice date

🧾 GSTIN

📊 Tax period

💰 Tax amount

💵 Interest

⚠️ Penalty

📋 Section/rule mentioned

📑 Alleged discrepancy

⏰ Reply due date

Then begin reconciliation.

📋 Step-by-Step Process to Reply to GST Notice

Step 1️⃣ Read the Notice Carefully

Read the complete notice.

Identify:

✔ Tax period

✔ Issue involved

✔ Tax amount

✔ Interest

✔ Penalty

✔ Relevant section

✔ Documents requested

✔ Reply deadline

Do not prepare a generic reply without understanding the exact allegation.

Step 2️⃣ Download the Relevant GST Returns

Collect:

📊 GSTR-1

📋 GSTR-3B

📑 GSTR-2B

📄 GSTR-9, where applicable

📈 GSTR-9C, where applicable

📦 E-way bill data

📑 Other GST statements

The reconciliation should cover the exact period mentioned in the notice.

Step 3️⃣ Reconcile With Books

Compare the GST portal information with:

📚 Sales register

📚 Purchase register

💰 General ledger

🏦 Bank statements

🧾 Tax invoices

📋 Credit/debit notes

📦 E-way bills

This helps establish whether the discrepancy is genuine or only a reporting/timing difference.

Step 4️⃣ Identify the Reason

Every difference should have an explanation.

For example:

Department’s turnover → ₹1 crore

Books turnover → ₹1 crore

GSTR-1 → ₹95 lakh

GSTR-3B → ₹1 crore

Difference → ₹5 lakh

Possible reason:

₹5 lakh invoice was reported in GSTR-3B but subsequently amended in GSTR-1.

The reply should explain the exact reason and provide supporting evidence.

Step 5️⃣ Prepare a Reconciliation Statement

A reconciliation table makes the reply much more professional.

Example:

Particulars Amount

Turnover as per Books ₹1,00,00,000

Turnover as per GSTR-1 ₹98,00,000

Turnover as per GSTR-3B ₹1,00,00,000

Difference ₹2,00,000

Reason Amendment/timing difference

Tax impact Nil

Supporting documents should be attached wherever necessary.

📊 Example — GSTR-1 vs GSTR-3B Difference

Suppose:

GSTR-1 = ₹80 lakh

GSTR-3B = ₹85 lakh

Difference = ₹5 lakh

Before accepting any tax demand, check:

✔ Credit notes

✔ Amendments

✔ Previous-period invoices

✔ Advances

✔ Export invoices

✔ Exempt supplies

✔ Nil-rated supplies

✔ Rounding differences

✔ Reporting errors

A proper reconciliation may establish that there is no additional tax liability.

📌 ITC Mismatch Notice

ITC-related notices are also common.

For example:

ITC claimed in GSTR-3B → ₹10 lakh

ITC appearing in GSTR-2B → ₹9 lakh

Difference → ₹1 lakh

Do not automatically assume that the entire ₹1 lakh is ineligible.

Investigate:

✔ Timing differences

✔ Supplier amendments

✔ Credit notes

✔ Invoices appearing in subsequent 2B

✔ RCM credit

✔ ISD credit

✔ Import IGST

✔ Reversal/reclaim

✔ Eligible ITC not reflected due to reporting issues

📋 ITC Reconciliation Format

Particulars Amount

ITC as per GSTR-2B ₹9,00,000

Add: Eligible timing differences ₹50,000

Add: Import IGST ₹30,000

Less: Ineligible ITC ₹10,000

Eligible ITC ₹9,70,000

ITC claimed ₹9,70,000

Difference Nil

A detailed reconciliation is much stronger than simply stating:

“There is no mismatch.”

📌 How to Reply to ASMT-10?

For an ASMT-10 notice, the taxpayer can furnish an explanation in FORM GST ASMT-11.

The GST rules specifically provide for ASMT-11 as the taxpayer’s response to the discrepancy communicated through ASMT-10.

A professional response should generally contain:

1️⃣ Reference to notice

2️⃣ Taxpayer details

3️⃣ Issue-wise response

4️⃣ Reconciliation

5️⃣ Explanation

6️⃣ Supporting documents

7️⃣ Tax/interest payment details, if applicable

8️⃣ Request for acceptance/closure

📌 How to Reply to DRC-01?

A DRC-01-related proceeding requires more careful attention because it may involve proposed tax, interest and penalty.

First identify the statutory basis of the notice and the period involved.

Then prepare:

📄 Issue-wise reply

📊 Tax calculation reconciliation

🧾 Invoice-level reconciliation

📋 Legal explanation

📑 Supporting documents

💰 Payment details, if liability is accepted

The reply should address every allegation separately.

⚠️ Never Give a Generic Reply

Avoid replies such as:

“Mismatch is due to technical error.”

“We will reconcile.”

“There is no liability.”

“Please close the notice.”

These statements are usually insufficient without evidence.

Instead write:

“The difference of ₹2,35,000 represents invoices pertaining to the previous tax period which were reported in the subsequent period. The relevant invoice-wise reconciliation is attached as Annexure A.”

This is much stronger.

📊 Issue-Wise Reply is Better

Suppose the notice contains three issues.

Issue 1 → Turnover mismatch

Issue 2 → ITC mismatch

Issue 3 → Interest

Do not give one paragraph covering everything.

Instead:

📌 Issue 1 — Turnover Difference

Explain the reason and provide reconciliation.

📌 Issue 2 — ITC Difference

Provide invoice-wise/vendor-wise reconciliation.

📌 Issue 3 — Interest

Provide calculation and payment details, if applicable.

💰 What If the Tax Demand is Correct?

If reconciliation confirms that additional tax is actually payable, do not submit a false explanation.

Instead:

✔ Calculate tax

✔ Calculate applicable interest

✔ Determine applicable penalty

✔ Make payment through the prescribed GST process

✔ Mention payment details in the reply

✔ Attach the payment challan/DRC-03 details, as applicable

The response should clearly state that the liability has been accepted and discharged, subject to the facts and applicable law.

📌 What If Only Part of the Demand is Correct?

This is very common.

Example:

Department demand → ₹5,00,000

Correct liability → ₹1,20,000

Incorrect demand → ₹3,80,000

The reply should clearly distinguish:

✔ Accepted amount

✔ Disputed amount

✔ Reason for dispute

✔ Supporting documents

This is better than either blindly accepting the entire demand or rejecting everything without explanation.

📑 Documents to Attach With GST Notice Reply

Depending on the issue, documents may include:

📊 GSTR-1

📋 GSTR-3B

📑 GSTR-2B

📚 Sales register

📚 Purchase register

🧾 Tax invoices

📋 Credit notes

📋 Debit notes

📦 E-way bills

🏦 Bank statements

📊 Ledger extracts

📑 Reconciliation statements

💰 DRC-03 payment proof, where applicable

📄 Agreements/contracts

📋 Relevant correspondence

📌 Invoice-Level Reconciliation

For complex notices, invoice-level reconciliation can be very useful.

Example:

Invoice No. Invoice Date Taxable Value GST GSTR-1 GSTR-3B Difference

INV-101 05/04/2026 ₹50,000 ₹9,000 Yes Yes Nil

INV-102 12/04/2026 ₹75,000 ₹13,500 Yes No Explained

INV-103 20/04/2026 ₹40,000 ₹7,200 Yes Yes Nil

Such a statement makes the officer’s verification easier.

📊 GSTR-1 vs GSTR-3B Reconciliation

A professional reconciliation may contain:

Particulars Taxable Value IGST CGST SGST

GSTR-1 ₹50,00,000 ₹2,00,000 ₹1,50,000 ₹1,50,000

GSTR-3B ₹49,00,000 ₹2,00,000 ₹1,45,000 ₹1,45,000

Difference ₹1,00,000 Nil ₹5,000 ₹5,000

Then explain the exact reason for each difference.

This is much more effective than submitting only a narrative response.

📌 What Happens After ASMT-11?

If the officer finds the explanation acceptable, FORM GST ASMT-12 may be issued communicating acceptance of the explanation.

Therefore, a well-prepared ASMT-11 reply can potentially resolve the discrepancy without further proceedings on that issue.

If the explanation is not accepted or no reply is furnished, further action may be initiated in accordance with the GST law. CBIC’s scrutiny instructions also provide for further action where the taxpayer does not respond or where the response does not resolve the discrepancy.

⏰ GST Notice Reply Deadline

For ASMT-10, the current CBIC rules page states that the notice specifies a period not exceeding 15 days from the date of service, while CBIC’s earlier scrutiny instruction provided a 30-day reply period and permitted further time where allowed by the proper officer. Therefore, the safest approach is to follow the exact deadline mentioned in the notice and seek an extension promptly if necessary.

Do not wait until the last day.

📌 Can You Ask for More Time?

If additional time is genuinely required to collect documents or complete reconciliation, a taxpayer may request an extension from the proper officer where permitted.

The request should explain:

✔ Nature of issue

✔ Documents being collected

✔ Reason additional time is required

✔ Expected date of submission

A specific and reasonable request is preferable to simply stating:

“Please give us more time.”
