What is a GST Audit?
A GST audit is a thorough examination of the records maintained by a taxpayer to verify the accuracy of tax paid, input tax credit claimed, and returns filed. Under GST laws, audits can be:
- Mandatory for businesses with turnover above the specified threshold.
- Departmental conducted by GST officers under Section 65 or 66.
- Special audits ordered under Section 66 by a Chartered Accountant or Cost Accountant nominated by the Commissioner.
Common GST Audit Issues
1. Mismatch Between GSTR-3B and GSTR-2A/2B
One of the most common GST audit issues is the discrepancy between GSTR-3B and GSTR-2A/2B. GSTR-3B is the monthly summary return, while GSTR-2A/2B reflects input tax credit (ITC) from suppliers.
🔹 Why It Happens:
- Suppliers not filing GSTR-1
- Incorrect GSTIN entered
- Timing mismatch of invoices
🔹 Consequences:
- Disallowance of ITC
- Notice from GST department
2. Excess or Ineligible ITC Claim
Claiming ineligible or excess input tax credit is a red flag during audits.
🔹 Common Mistakes:
- ITC claimed on personal or non-business expenses
- ITC on blocked credits (e.g., food, entertainment, motor vehicles)
- ITC claimed without valid tax invoice
🔹 Resolution:
- Regular reconciliation of purchase register with GSTR-2B
- Ensure vendor compliance
3. Non-Reversal of ITC
ITC must be reversed in certain situations, such as:
- Non-payment to vendors within 180 days
- Inputs used for exempt supplies or personal use
🔹 Audit Risk:
Failure to reverse ITC in such cases is considered non-compliance and may result in interest and penalties.
4. Incorrect Classification of Goods or Services
Wrong HSN/SAC code usage leads to charging incorrect GST rates.
🔹 Impact:
- Underpayment or overpayment of GST
- Show-cause notice from department
🔹 Best Practice:
- Refer to CBIC rate notifications
- Use HSN lookup tools or consult professionals
5. Errors in E-Way Bills
Mismatch or errors in e-way bill details and tax invoices can trigger scrutiny.
🔹 Common Issues:
- Wrong vehicle number
- Inconsistent invoice and e-way bill values
- Missing e-way bill for goods movement above threshold
6. Delay in Filing Returns
Late or non-filing of GSTR-1, GSTR-3B, or annual returns creates suspicion.
🔹 Audit Consequences:
- Penalties and interest
- Suspension of GSTIN
- Blocking of e-way bill generation
