As a CFO or Director of Finance, you're likely familiar with the self-assessment nature of India's GST regime. However, what happens when tax authorities decide to verify your company's compliance through an audit under Section 65?
This comprehensive guide will help you understand the audit process, prepare your organization effectively, and manage potential outcomes strategically.
The GST system operates on trust - businesses self-assess and file returns, but the government reserves the right to verify compliance. Section 65 of the CGST Act, 2017 provides tax authorities with comprehensive powers to examine your company's records, returns, and documents. Think of it as a health check-up for your GST compliance, where authorities verify whether your declared turnover, taxes paid, refunds claimed, and input tax credits are accurate.
Unlike the routine statutory audits under Section 35(5) that you might be familiar with, or the more intensive special audits under Section 66, Section 65 audits occupy a middle ground. They're discretionary, risk-based examinations that can significantly impact your organization's financial position and reputation if not managed properly.
Understanding why companies get selected for audit helps you assess and manage your risk profile. The selection process follows a sophisticated risk-based methodology that considers multiple factors:
Significant variations in turnover compared to previous years
Unusual patterns in input tax credit claims
Mismatches between GSTR-3B and GSTR-2A filings
Mismatches between E-Way Bill and GSTR-1
Non-payment to Creditors within 180 days leads to reversal of ITC
Abnormal financial ratios like gross profit margins or sales-purchase ratios
Your past behavior influences future scrutiny. Delayed return filings, previous compliance issues, or patterns of amendments can increase your audit risk. Think of it as a credit score for tax compliance - every action contributes to your overall risk profile.
Tax authorities categorize businesses based on turnover and complexity. Large taxpayers receive 40% of available audit resources, making them more likely targets. If your company operates in sectors known for compliance challenges or has multi-location operations, you're automatically in a higher risk category.
Your audit journey begins when you receive Form GST ADT-01, providing at least 15-30 working days' advance notice. This isn't just a formality - it's your roadmap for the audit. The notice specifies which documents the auditors want to examine and where the audit will take place (either at your premises or the tax office).
Strategic Tip: Use these 15-30 days wisely. This is your preparation window, not a grace period. Mobilize your finance team immediately to gather and review the requested documents.
The audit officially begins when you make documents available to the auditors or when they arrive at your premises, whichever is later. Here's a critical insight: audits must be completed within three months, though this can extend to nine months with proper justification.
Manufacturing companies typically face longer audits than service providers
Multi-location businesses require more time
Complex supply chains or high transaction volumes extend timelines
The auditor's initial findings may trigger deeper examination
During the audit, officers will scrutinize various aspects of your GST compliance:
Verification of financial statements against GST returns
Examination of purchase and sales invoices
Review of input tax credit documentation
Analysis of exemptions and deductions claimed
Checking the accuracy of tax rates applied
Your Rights During This Phase: You can have your regular employees handle the audit, or engage professionals like Chartered Accountants or advocates. This representation right is crucial - it allows your business operations to continue while specialists manage the audit process.

Within 30 days of audit completion, you'll receive Form GST ADT-02 detailing the findings. Here's a crucial point many executives miss: this report isn't a tax demand - it's a communication of findings that may lead to formal proceedings.
The report will categorize discrepancies into:
Short payment of various tax components (IGST, CGST, SGST, Cess)
Incorrectly claimed input tax credits
Erroneous refund claims
Interest and Penalties
Other compliance gaps
When discrepancies are found, you face a strategic crossroads that can significantly impact your financial exposure:
Option 1: Voluntary Compliance Under Section 73(5) If the findings are accurate, voluntary payment offers several advantages:
Potential reduction in penalties
Faster closure of the matter
Preservation of goodwill with tax authorities
Avoiding lengthy litigation
Option 2: Contesting the Findings If you disagree with the audit findings, formal proceedings will follow under either:
Section 73: For non-fraudulent discrepancies (3-year time limit)
Section 74: For cases involving fraud or willful misstatement (5-year time limit, higher penalties)
If authorities proceed with formal action, you'll receive Form GST DRC-01. This is when the stakes become real - you have just 7 days to respond initially (to avoid GSTR-1 filing restrictions) and 30 days for a comprehensive response.
Strategic Consideration: The distinction between Sections 73 and 74 is critical. Section 74 proceedings carry penalties ranging from 15% to 100% of the tax amount, while Section 73 penalties are significantly lower. The characterization of your case can dramatically impact your financial exposure.
Think of audit preparation as insurance - the investment you make before an audit significantly reduces your exposure during one. Here's your preparation framework:
Maintain real-time reconciliation between books of accounts and GST returns
Ensure all invoices have proper supporting documentation
Create audit trails for all input tax credit claims
Document the business rationale for exemptions and deductions
GSTR-1 and GSTR-3B reconciliation
Input tax credit eligibility verification
Proper tax rate application
Timely return filing compliance
Automated reconciliation capabilities
Mismatch identification tools
Audit trail maintenance
Document management systems
Designate a single point of contact for auditors
Maintain professional, cooperative relationships
Document all auditor requests and your responses
Seek clarification on ambiguous requests immediately
Provide only what's specifically requested
Ensure all provided documents are complete and accurate
Maintain copies of everything submitted
Track timelines for all submissions
Analyze the audit report thoroughly with your tax advisors
Quantify the financial impact of findings
Assess the strength of your position on disputed items
Make the voluntary compliance vs. litigation decision
Strengthen weak compliance areas
Update internal controls
Enhance team training
Refine your GST processes
As a CFO or Finance Director, you need to understand the potential financial implications:
Tax dues identified
Interest charges (18% per annum)
Penalties (varying based on Section 73 vs. 74)
Professional fees for representation
Management time and attention
Potential reputational impact
Opportunity cost of locked working capital
System and process upgrade investments
Evaluate your audit readiness across five key dimensions:
Documentation Quality: Are your records audit-ready at any time?
Process Robustness: Do you have documented GST compliance processes?
Team Capability: Is your team trained to handle audit queries?
Technology Support: Do your systems support compliance and audit requirements?
Professional Support: Do you have access to specialized GST expertise?
Develop a documented audit response plan that includes:
Roles and responsibilities matrix
Document production protocols
Escalation procedures
Communication guidelines
Decision-making frameworks for voluntary compliance
Proactive Compliance is Cost-Effective: The cost of maintaining robust compliance is fraction of potential audit exposures.
Early Engagement Matters: How you respond in the first 30 days after receiving audit findings can significantly impact outcomes.
Documentation is Your Defense: Well-maintained records and clear audit trails are your best protection against adverse findings.
Professional Support is Strategic: Engaging specialized professionals during audits isn't an expense - it's risk management.
Learn from Every Audit: Whether findings are favorable or adverse, each audit provides insights for strengthening your compliance framework.
GST audit under Section 65 need not be a crisis - with proper preparation and strategic management, it becomes an opportunity to validate your compliance processes and identify improvement areas. As financial leaders, your role is to ensure your organization views GST compliance not as a regulatory burden but as a business discipline that protects value and enhances operational efficiency.
Remember, in today's transparent tax environment, the question isn't whether you'll face an audit, but when. The organizations that thrive are those that are always audit-ready, treating compliance as an ongoing journey rather than a destination.
By implementing the strategies outlined in this guide, you'll not only minimize audit risks but also build a compliance culture that serves as a competitive advantage in the marketplace. After all, in the world of GST, the best audit defense is a good compliance offense.
