Everything you need to know about Audit under GST

The Goods and Services Tax (GST) is a major milestone in India’s tax system, introduced in July 2017. By replacing multiple indirect taxes with a single, unified structure, GST has simplified taxation for businesses. However, with this shift, compliance has become essential—and that’s where GST audits come in.

A GST audit is a thorough check of a taxpayer’s financial records, GST returns, and other related documents. The purpose? To ensure that:

• The right amount of tax has been paid.
• Input Tax Credits (ITC) are claimed correctly.
• Refunds, if any, are processed accurately.

But GST audits go beyond just spotting mistakes. They aim to:

• Promote transparency.
• Enhance trust between taxpayers and authorities.
• Prevent tax evasion.

In short, GST audits are not just about compliance—they are about building a system of accountability and improving governance in India’s tax landscape.

In this guide, you will learn everything about GST audits—what they are, why they matter, and how to navigate them effectively.

What is a GST Audit?

A GST audit is a detailed review of financial records, tax returns, and related documents to ensure compliance with GST laws. It checks whether taxpayers have correctly assessed their tax liabilities, claimed eligible input tax credits (ITC), and filed returns without errors or omissions.

The legal definition of an audit under GST is provided in Section 2(13) of the Central Goods and Services Tax (CGST) Act, 2017:

“Audit means the examination of records, returns, and other documents maintained or furnished by a registered person under this Act or the rules made thereunder, to verify the correctness of turnover declared, taxes paid, refund claimed, and input tax credit availed, and to assess compliance with the provisions of this Act or the rules.“

In simple terms, a GST audit acts as a financial health check for businesses to ensure compliance with GST regulations.

Why is a GST Audit Important?

• Ensures accuracy and compliance with GST laws.
• Detects errors, discrepancies, or fraud in tax payments.
• Identifies improper claims of input tax credit (ITC) or refunds.
• Reduces legal risks by rectifying mistakes before penalties are imposed.
• Promotes accountability and transparency in financial reporting.
• Helps businesses avoid fines, penalties, and litigations through timely compliance.

For businesses, GST audits act as a safeguard against potential tax disputes and ensure smooth operations by validating the correctness of their tax records.

Purpose of GST Audit

The primary objectives of a GST audit include:

• Verification of Turnover: Ensures the correct reporting of sales and revenue.
• Input Tax Credit (ITC): Checks whether ITC claims are valid and match purchase records.
• Refunds and Payments: Confirms that refunds are claimed appropriately and payments are made accurately.
• Compliance Monitoring: Ensures adherence to GST rules, filings, and deadlines.
• Error Identification: Detects mistakes or discrepancies to help businesses rectify them before legal action.

Types of GST Audits

GST audits are categorized into various types, each serving a specific purpose to ensure compliance with GST laws. Here’s an overview of the main types:

1. Departmental Audit (Audit by Tax Authorities)

This is a routine GST audit conducted by tax authorities to verify that businesses accurately calculate and pay their tax liabilities.

• Authority: As per Section 65 and Rule 101(3) of the GST Audit Rules, the Commissioner or an authorized officer can initiate this audit.
• Process:
  • Conducted at the taxpayer’s place of business or registered office.
  • The taxpayer receives prior notice in Form GST ADT-01 at least 15 days before the audit.
  • The audit must be completed within three months of commencement, with an extension of up to six months allowed if necessary.
• Outcome:
  • Findings are shared in Form GST ADT-02 within 30 days of audit completion.
  • If discrepancies like improper ITC claims are identified, actions are taken under Section 73 or Section 74 of the GST Act.

2. Statutory Audit

This audit is mandated for certain entities under legal requirements, such as public companies and government organizations.

• Previous Requirement:
  • Until July 30, 2021, taxpayers with an annual turnover exceeding ₹2 crore were required to have their accounts and returns audited by a Chartered Accountant (CA) or Cost Management Accountant (CMA).
  • The audited accounts, along with the reconciliation statement (GSTR 9C), had to be submitted.
• Current Process:
  • For businesses with an annual turnover below ₹5 crores, self-certification is allowed for GSTR-9C. However, for businesses with a turnover exceeding ₹5 crores, CA certification is mandatory.

3. Special Audit

This audit is conducted when the tax authorities suspect complex transactions or discrepancies in a taxpayer’s filings.

• Authority: Under Section 66 and Rule 102, an Assistant Commissioner (or higher rank) can order this audit.
• Conditions for Audit:
  • Incorrect value declaration.
  • Excessive or unusual credit claims.

  • The taxpayer is instructed to get their accounts audited by a CA or CMA within 90 days (extendable by another 90 days).
  • Findings are shared through Form GST ADT-04.
• Expense: Costs of the special audit are borne by the Commissioner’s office.

4. Limited Scrutiny

This is a focused audit conducted in cases where tax authorities suspect non-compliance with GST laws.

• Purpose: To verify:
  • Accuracy of tax returns filed.
  • Timely payment of taxes.
  • Adherence to other GST provisions.

5. Taxpayer-Initiated Audit

In this type of audit, the taxpayer voluntarily reviews their own compliance with GST regulations.

• Objective:

  • Verify proper tax payments and ITC claims.
  • Identify and correct any discrepancies.

By understanding these types of audits, businesses can better prepare for compliance and ensure smooth operations under GST regulations.

Key Points for a GST Departmental Audit

A departmental audit under GST is conducted by tax authorities to ensure compliance with tax laws. It involves verifying documents, tax returns, and financial records. Businesses need to be prepared for these audits to avoid penalties and disputes.

1. Prior Notice and Timeline

Taxpayers are notified at least 15 days in advance before the audit begins. This allows businesses enough time to prepare their records.

The audit must be completed within 3 months from the date it starts, although extensions can be granted in exceptional cases.

2. Location of the Audit

Audits are conducted either at:

• The taxpayer’s place of business, ensuring access to original records.
• The tax office, where copies of required documents may need to be submitted.

3. Document Requirements

Businesses must provide self-certified copies of documents, such as:

• GST Returns (GSTR-1, GSTR-3B, GSTR-9)
• Invoices and purchase orders
• Ledger accounts
• ITC claim records

Tax authorities may also request additional records during the audit.

4. Tax Liability Assessment

One of the main objectives of the audit is to check whether tax liability has been accurately calculated.

• If errors or discrepancies are found, the taxpayer will need to pay the additional tax, along with any applicable interest or penalties.
• Taxpayers may also be asked to explain any irregularities before finalizing the liability.

5. Stock Verification

Tax authorities may inspect the stock to verify quantities and assess any mismatches between physical stock and accounting records.

Unlike search and seizure operations, departmental audits focus only on verifying stock and do not involve forcibly searching the premises.

6. Premises Access and Restrictions

Authorities cannot search or seize goods or documents without prior authorization.

However, they are allowed to:

• Inspect the premises for compliance.
• Request clarifications regarding transactions and tax positions.

7. Audit Completion Report

After the audit, authorities issue a report detailing findings. This includes:

• Errors or mismatches in filings.
• Suggestions for corrections or penalties.
• Any demand for additional tax payment.

Businesses can appeal against these findings if they disagree with the observations.

A departmental audit focuses on compliance and tax accuracy. Being prepared with organized records, timely clarifications, and a clear understanding of GST laws can make the audit process smooth and hassle-free.

How to Prepare for a GST Departmental Audit

Preparing for a GST departmental audit requires meticulous organization and proactive planning to ensure compliance with GST laws. Proper preparation can help businesses avoid errors, penalties, and delays during the audit process.

1. Review GST Returns

Carefully examine all GST returns (e.g., GSTR-1, GSTR-3B, and GSTR-9) filed with the authorities.

• Ensure that turnover, tax payments, and input tax credits (ITC) match the financial records.
• Reconcile purchase and sales registers with filed returns to identify discrepancies in invoices and credits.

Tip: Resolve errors before the audit begins to reduce the risk of penalties.

2. Organize Financial Records

Maintain an organized record-keeping system to provide quick access to required documents. Key records include:

• Tax invoices, e-way bills, and receipts for sales and purchases.
• Payment records, including challans and refund claims.
• Input tax credit (ITC) registers and ledgers.
• Bank statements to validate transactions.

Having these documents ready reduces delays and builds confidence during audits.

3. Train Your Staff

Ensure that your accounting and finance teams are familiar with GST laws and compliance requirements.

• Assign responsibilities for document preparation and audit coordination to specific team members.
• Provide training sessions on GST rules and updates to keep the staff informed.

Tip: Designate a point-of-contact who can interact with auditors and clarify doubts.

4. Maintain a GST Compliance Profile

Develop a GST compliance profile that consolidates all key data, such as:

• Tax liability reports.
• Details of exemptions claimed.
• ITC summaries with eligibility checks.
• Reverse charge mechanism (RCM) applicability.

This profile acts as a snapshot of your GST compliance, making it easier for auditors to assess your records.

5. Track Audit Progress

Use a checklist or audit tracking tool to monitor the audit process.

• Keep records of communications with authorities.
• Log any queries raised by auditors and responses provided.
• Track the timeline and status of the audit to avoid missing deadlines.

6. Review Legal Positions and Opinions

Document any legal interpretations or opinions obtained for complex transactions or disputes.

• Maintain copies of legal correspondence or advance rulings to justify positions taken in tax returns.
• Use professional opinions to defend contentious issues during audits.

Checklist for Audit Readiness

Area	Key Actions
Tax Returns	Reconcile turnover, ITC claims, and tax payments with records.
Invoices and Documents	Organize invoices, e-way bills, purchase orders, and ledgers.
Staff Training	Ensure staff is aware of GST rules and audit procedures.

Importance of GST Audits for Compliance

GST audits are more than just a legal requirement—they play a vital role in ensuring businesses operate transparently and stay compliant with tax laws. Ignoring or mishandling audits can lead to severe penalties, disputes, and even damage a company’s reputation.

A. Why Are GST Audits Important?

1. Ensures Correct Tax Liability
   GST audits verify whether taxes have been accurately calculated and paid. They help identify underpayments or overpayments, ensuring compliance with GST laws.
2. Prevents Penalties and Legal Actions
   Non-compliance can result in hefty fines, interest charges, and even legal cases. Regular audits reduce this risk by catching errors early.
3. Builds Trust and Transparency
   Audits demonstrate a company’s commitment to ethical business practices, improving relationships with tax authorities and stakeholders.
4. Strengthens Internal Processes
   Businesses often streamline their accounting systems, document management, and compliance practices during audits. This improves efficiency in the long run.
5. Aids in Tax Planning
   Audits provide insights into tax-saving opportunities, ensuring businesses make the most of available exemptions and deductions.

B. Compliance Risks Without Audits

Risk	Impact on Business
Missed Tax Payments	Attracts penalties, interest charges, and legal notices.
Incorrect ITC Claims	Leads to denial of credit and repayment with penalties.
Unorganized Records	Results in delays, errors, and non-cooperation during audits.
Non-Filing of Returns	Causes suspension of GST registration and business disruptions.
Fraud or Misreporting	May result in criminal proceedings and reputational damage.

C. Real-World Impact of GST Audits

Consider this scenario:
A company failed to reconcile ITC claims with vendor invoices, leading to overclaims. During a GST audit, the error was detected, and the company had to pay not only the extra tax but also penalties and interest.

However, a well-prepared company with organized records and trained staff can defend its claims effectively, avoiding financial losses and litigations.

D. Proactive Compliance Saves Costs

Businesses that conduct internal reviews and voluntary audits before official audits:

• Minimize the risk of penalties.
• Improve their processes.
• Save time and resources spent on handling disputes later.

Hence, GST audits are not just about legal compliance but also about business efficiency. They safeguard against penalties, ensure proper tax payments, and build credibility with stakeholders.
