GST ADT-01 Notice Reply — Section 65 Audit Guide | FinTax24

TL;DR

Form GST ADT-01 is a departmental audit notice issued under Section 65 of the CGST Act. The tax office gives you at least 15 working days of advance intimation. You must furnish your books, sales records, purchase registers, and tax reconciliations. If you need more time, submit a written extension request promptly. Resolving discrepancies early prevents heavy penalties and show cause notices in Form GST DRC-01.

Quick Answer: What Is Form GST ADT-01?

Form GST ADT-01 is an official notice for a departmental GST audit. The tax department issues it under Section 65 of the Central Goods and Services Tax (CGST) Act, 2017, and the Gujarat Goods and Services Tax (GGST) Act, 2017. It is read with Rule 101(2) of the CGST Rules, 2017.

When you receive this notice, it means the proper officer has selected your business for a detailed tax audit. The notice informs you of the audit scope. It specifies the financial years under review. It also lists the books of accounts, ledgers, and reconciliation statements you must present.

By law, the tax authority must give you at least 15 working days prior notice before starting the audit.

Why Do Tax Authorities Issue Form GST ADT-01?

Under the GST self-assessment model, taxpayers assess their own taxes. The tax department uses risk-based computerized parameters to identify taxpayers for an in-depth audit. A business may receive Form GST ADT-01 for several key reasons:

1. Turnover Mismatches: Substantial variations between sales declared in GSTR-1, tax paid in GSTR-3B, and revenue reported in audited balance sheets or income tax returns (Form 3CD).
2. High Input Tax Credit (ITC) Ratios: Claiming higher ITC compared to industry benchmarks or substantial differences between GSTR-2B and GSTR-3B.
3. Inverted Duty Structure or Export Refunds: Substantial refund claims under inverted duty structures or zero-rated export supplies without payment of tax.
4. Transactions with Non-Compliant Vendors: Buying goods or services from suppliers whose registrations were cancelled or flagged for non-filing.
5. High Value Reverse Charge Supplies: Omission or under-reporting of Reverse Charge Mechanism (RCM) liabilities on goods transport agency (GTA) services, director fees, or legal expenses.

For example, a ceramic manufacturer in Morbi buying packing materials from multiple states may get audited for inverted duty refund calculations. A textile trading firm in Surat might face review for job-work inward and outward registers. An engineering unit in Rajkot may need to verify capital goods ITC depreciation under Rule 43.

Form GST ADT-01 vs Form GST ASMT-10 vs Form GST DRC-01

Taxpayers often confuse audit notices with scrutiny notices and show-cause orders. Here is how they differ:

Feature	Form GST ADT-01	Form GST ASMT-10	Form GST DRC-01
Statutory Provision	Section 65 (Departmental Audit)	Section 61 (Scrutiny of Returns)	Section 73 / 74 / 74A (Demand Notice)
Trigger	Broad risk selection of accounts	Specific return discrepancy	Unresolved tax short-payment or audit finding
Initial Reply Time	At least 15 working days	30 days	30 days
Scope	Complete books, bank statements, and stock	Specific parameter flagged in return	Formal tax, interest, and penalty demand
Conduct Location	Tax office or business place	Portal-only submission	Portal / personal hearing
Concluding Form	Form GST ADT-02 (Audit Report)	Form GST ASMT-12 (Acceptance Order)	Form GST DRC-07 (Summary Order)

While a scrutiny notice under ASMT-10 focuses on specific discrepancies in filed returns, Form GST ADT-01 opens a comprehensive examination of all financial books and compliance records. For return scrutiny matters, you can read our guide on Form GST ASMT-10 notice replies. If issues remain unresolved, the department issues a demand in Form GST DRC-01 notice.

Final Audit Report in Form GST ADT-02 (Within 30 Days of Completion)

1. Receipt of Form GST ADT-01 Notice

The officer sends the notice electronically on the GST portal under the “Additional Notices and Orders” section. It specifies whether the audit will happen at the officer’s desk (desk audit) or at your principal place of business. It includes an annexure listing required records.

2. Collating Records and Preparing Reconciliations

You must prepare all requested records within the 15 working days window. Do not provide raw, unverified data. Prepare clear reconciliation sheets linking your invoices to monthly returns and financial statements.

3. Requesting an Extension (If Needed)

If your accounting records are voluminous, or key staff are unavailable, submit an extension letter online immediately. State practical reasons and request a reasonable extension, typically 15 to 30 days. Most officers grant reasonable extensions when requested early in writing.

4. Conduct of the Audit

Under Section 65(4), the audit must finish within three months from the date of commencement. The Commissioner may extend this period by up to six months for complex cases. Commencement begins on the date you furnish your books and records to the officer, or when the officer accesses your business premises, whichever is later.

5. Replying to Audit Queries

During the audit, the officer issues memos or observation letters. You must reply to each point with supporting documents, invoices, e-way bills, and relevant statutory provisions. If you agree with any short-payment, paying tax with interest via Form GST DRC-03 at this stage can waive or reduce penalties.

6. Issuance of Form GST ADT-02 Audit Report

Under Section 65(6) and Rule 101(5), the proper officer must finalize the audit findings within 30 days of completing the audit. The officer issues Form GST ADT-02, detailing the findings, reasons, and your rights and obligations.

Document and Reconciliation Checklist for GST Audit

Preparing a thorough audit file helps complete the audit smoothly. Keep the following documents organized:

• Audited Financial Statements: Balance sheets, profit and loss statements, and Form 3CD tax audit reports for the audit period.
• Sales and Outward Supply Ledgers: Month-wise sales registers showing taxable value, CGST, SGST, IGST, cess, and exempt supplies.
• Purchase and Inward Supply Registers: Complete purchase registers matching with Input Tax Credit claims in monthly returns.
• Reconciliation Statements:
  • GSTR-1 vs GSTR-3B revenue reconciliation.
  • GSTR-2B vs Books of Accounts purchase and credit reconciliation.
  • Balance Sheet turnover vs GST return gross turnover reconciliation.
• Fixed Asset Register: Invoices and ITC calculation sheets for plant, machinery, and office assets, showing Rule 43 calculations.
• E-Way Bills and Delivery Challans: Consignment records, transporter receipts, and delivery challans for job-work or branch transfers.
• Reverse Charge Mechanism (RCM) Records: Payment vouchers and tax payment proofs for freight (GTA), legal fees, and import of services.
• Bank Statements: Bank statements for all active business accounts with cross-references for major receipts and payments.
• Stock and Inventory Records: Physical stock registers, raw material inward registers, and finished goods ledgers showing yield or loss percentages.

How to Draft Your Reply to Form GST ADT-01

A structured, factual reply prevents unnecessary escalation. Follow these practical rules when drafting:

1. Use a Tabular Format: Group each audit point from the notice into a structured table. Include columns for Observation, Taxpayer Explanation, Legal Reference, and Annexure Number.
2. Support with Reconciliations: Always attach signed reconciliation sheets. For example, explain timing differences between income tax TDS returns and GST sales invoices clearly.
3. Cite Statutory Rules and CBIC Circulars: Quote specific sections of the CGST Act, CGST Rules, and relevant department circulars. For instance, cite circulars clarifying export documentation or discounts under Section 15(3).
4. Number Every Annexure: Clearly label and index each supporting document. A well-organized bundle helps the officer verify your contentions quickly.
5. Separate Admitted Tax from Disputed Points: If you find an inadvertent clerical error, admit it clearly. Pay the tax and applicable interest under Section 50 via Form GST DRC-03. Submit the payment receipt along with your reply to close the issue.

What Happens After the Audit? (Form GST ADT-02 and DRC-01)

When the audit concludes, the proper officer issues Form GST ADT-02. This document contains:

• Specific observations and discrepancies verified during the audit.
• Quantified tax liabilities, interest, or ineligible credits.
• Points where the officer accepted your explanations and closed the query.

If the officer finds unpaid tax or wrongly availed ITC and you do not pay, the matter moves to formal demand proceedings. The officer initiates action by issuing a notice under Section 73 (non-fraud cases) or Section 74 (fraud or willful misstatement cases), or Section 74A for financial year 2024-25 onwards. The demand arrives as a summary in Form GST DRC-01.

Common Mistakes

Many businesses make avoidable errors during a Section 65 departmental audit. Avoid these frequent mistakes:

1. Delaying the initial response beyond 15 working days without filing a written request for an extension.
2. Submitting raw accounting tallies without first preparing reconciliations between GSTR-3B, GSTR-1, and financial statements.
3. Overlooking reverse charge tax obligations on transport agency bills, legal expenses, and rent payments.
4. Forgetting to reverse input tax credit for vendor invoices unpaid past 180 days under Section 16(2).
5. Failing to produce delivery challans or Form ITC-04 records for goods sent out for job-work.
6. Leaving capital goods credit unsegregated from normal input tax credits without proper Rule 43 working sheets.
7. Making verbal arguments during audit meetings without submitting signed written explanations and documentary exhibits.
