GST Notices and Scrutiny: How to Handle Common GST Notices with Confidence

Getting a GST notice can be scary, especially if it’s your first time. The email or SMS usually arrives with a formal-looking PDF attached, and many business owners immediately fear the worst. In reality, a large number of GST notices are about mismatches, clarifications, or routine verification – and can be handled calmly with the right approach.

In this guide, I’ll explain common types of GST notices in simple terms, what they typically mean, and the practical steps you should take to respond. The goal is to replace panic with a clear, methodical process.

Why Do You Get GST Notices?

Broadly, notices arise due to:

• Mismatches between:
• GSTR‑1 vs GSTR‑3B
• GSTR‑3B vs GSTR‑2A/2B
• GST returns vs e‑way bill data or income tax data
• Non-filing or delayed filing of returns
• Suspected ineligible ITC or risky patterns flagged by the system
• Routine scrutiny or audit for specific periods or turnovers

Not every notice means you’ve done something wrong, but every notice does need to be taken seriously and handled within the specified timelines.

Common Types of GST Notices (Conceptual Overview)

While section numbers and formats can vary, you’ll often see notices related to:

• Non-filing of returns: Reminders or show-cause for not filing GSTR‑3B/GSTR‑1
• Mismatch in liability vs payment: Where sales reported in GSTR‑1 are not matched by tax paid in GSTR‑3B
• ITC mismatch/suspected excess ITC: Where ITC claimed in 3B is not adequately supported by 2A/2B or appears unusual
• Scrutiny of returns: Requests for books, reconciliations, and explanations for a specific period
• Audit-related communication: For selected taxpayers, often involving deeper examination

The notice itself usually mentions:

• Relevant sections/rules
• Period under scrutiny
• Issues observed or data points highlighted
• Required actions and timelines

Step 1: Don’t Ignore the Notice – Read It Properly

Your first task is to:

• Download the notice PDF from the GST portal
• Read:
• The period it refers to
• The specific returns or data mentioned (GSTR‑1, 3B, 2A/2B, e‑way bills, etc.)
• The reason or issue described
• The deadline for response

Even if the language is formal, try to extract the core question:

• “Why is tax in 3B lower than tax implied by 1?”
• “Why is ITC so much higher than what appears in 2B?”
• “Why have you not filed XYZ return?”
• “Please provide documents to support ABC entries.”

Step 2: Gather Relevant Data and Reconcile

Depending on the notice type, you may need:

• Filed GSTR‑1 and GSTR‑3B for the period
• GSTR‑2A/2B for ITC-related issues
• Accounting records:
• Sales register
• Purchase/expense register
• Ledger-wise details (e.g., GST output, input, round-off accounts)

Perform a reconciliation:

• For GSTR‑1 vs 3B:
• Check if some invoices were amended or reported in a different period
• Verify if certain zero-rated or exempt supplies were treated differently

• For ITC issues:
• Reconcile ITC claimed vs ITC appearing in 2B
• Identify invoices where supplier hasn’t filed or filed incorrectly
• Remove clearly ineligible or blocked credits if any slipped through

Document your workings – they’ll form the backbone of your reply.

Step 3: Draft a Clear, Factual Reply

When replying:

• Be polite and factual, not emotional
• Address each issue raised, one by one
• Attach or reference:
• Reconciliation statements (Excel summaries)
• Copies of key invoices where relevant
• Any clarifications about amended returns or later corrections

If you recognize genuine mistakes:

• Acknowledge them
• Explain corrective steps taken (e.g., payment via DRC‑03, amendments in subsequent returns)

Revenue authorities generally respond better to transparent, organized replies than to evasive, incomplete ones.

Step 4: Pay Due Amounts and Correct Returns If Needed

If your reconciliation shows:

• Underpaid tax, or
• Excess ITC claimed

then:

• Use the prescribed mechanism (often DRC‑03) to pay differential amounts and interest where applicable
• Reflect corrections/amendments in subsequent returns as per guidance

Attach proof of such payment/correction with your reply. This often makes resolution smoother.

Step 5: Learn from the Notice – Strengthen Processes

After handling the immediate issue, ask:

• What led to this notice?
• Weak reconciliation?
• Poor vendor compliance and ITC control?
• Habitual late filing?

Then:

• Tighten your monthly reconciliation process (see your ITC guide)
• Improve vendor onboarding and monitoring
• Set up calendar reminders for all return due dates (see your compliance calendar guide)

The aim is to reduce the chance of similar notices in future.

Final Thoughts

GST notices are part of the system’s checks and balances. While they should never be ignored, they also don’t need to cause panic if you approach them with calm, data, and timely action.

Whenever you receive a notice:

• Understand the core issue
• Reconcile your data carefully
• Respond within the deadline, with supporting documents
• Fix underlying process gaps

For complex or high-stakes cases, don’t hesitate to involve a GST practitioner or chartered accountant with experience in handling departmental communication.
