5 Reasons You Got a GST Notice & How to Fix It Fast


Received a GST notice and don't know what to do? Take a deep breath. You are not alone. Hundreds of business owners across Coimbatore receive GST notices every month — and most of them are fixable. At Wintrust Solutions, we handle GST notices every day. Here's what you need to know.


Why Did You Get a GST Notice?

The GST department sends notices for specific reasons. Here are the 5 most common ones:


Reason 1 — Mismatch Between GSTR-1 and GSTR-3B

This is the #1 reason businesses get GST notices in India.

If the sales you declared in GSTR-1 don't match what you paid tax on in GSTR-3B, the GST system automatically flags your account and generates a notice.

✅ Fix: Reconcile both returns immediately. File an amendment return if needed. A tax consultant can do this in hours.


Reason 2 — Input Tax Credit (ITC) Mismatch

If you claimed ITC that doesn't match your supplier's GSTR-1 filings, you will receive a notice under Section 61.

This often happens when your supplier files late or incorrectly — not your fault, but still YOUR problem to solve.

✅ Fix: Cross-check your purchase register with GSTR-2B every month. Follow up with suppliers who file late.


Reason 3 — Late Filing of GST Returns

Missing even one GST return deadline can trigger a notice — plus heavy penalties and interest.

GSTR-1, GSTR-3B and annual returns all have strict deadlines. One missed filing creates a chain reaction of notices.

✅ Fix: File all pending returns immediately, even with late fees. Clearing the backlog stops further notices from coming.


Reason 4 — Turnover Exceeds Registration Threshold

If your business turnover crossed ₹40 lakhs (goods) or ₹20 lakhs (services) but you haven't registered for GST yet, expect a notice soon.

The GST department cross-references data from banks, income tax and TDS to detect unregistered businesses.

✅ Fix: Register for GST immediately and file returns from the date you crossed the threshold. Voluntary compliance always gets better treatment from the department.


Reason 5 — Scrutiny of High ITC Claims

If your Input Tax Credit claims are unusually high compared to your industry average, the GST department may scrutinise your account and issue a notice seeking explanation.

✅ Fix: Maintain proper purchase invoices, e-way bills and vendor details. A professional response with supporting documents usually resolves this quickly.


What Happens If You Ignore a GST Notice?

Never ignore a GST notice. Ignoring leads to:

  • Escalation to GST Audit
  • Best Judgement Assessment — department decides your tax
  • Penalties up to 100% of tax amount
  • Cancellation of your GST registration
  • Bank account attachment in serious cases

Always respond within the deadline mentioned in the notice.


Types of GST Notices and What They Mean

Notice Type Section Reason Deadline to Reply
ASMT-10 Section 61 Scrutiny of returns 30 days
ASMT-14 Section 63 Best judgement assessment 15 days
DRC-01 Section 73/74 Tax demand with penalty 30 days
REG-03 Section 25 Registration clarification 7 days
REG-17 Section 29 Cancellation of registration 7 days

How to Respond to a GST Notice — Step by Step

Step 1 — Read the notice carefully
Note the notice number, date, section, and reply deadline. Never miss the deadline — even one day late can result in an ex-parte order against you.

Step 2 — Identify the exact reason
Is it a return mismatch? An ITC issue? A demand for documents? Understanding the exact reason determines your response strategy.

Step 3 — Gather your documents
Collect all relevant invoices, bank statements, return acknowledgements, and payment receipts. The stronger your documentation, the stronger your reply.

Step 4 — Draft a professional reply
Your reply must address every point in the notice with supporting evidence. A vague or incomplete reply is almost always rejected.

Step 5 — File the reply on the GST portal
Log into gst.gov.in, go to Services → User Services → View Notices and Orders → File reply against the specific notice.

Step 6 — Follow up
After filing your reply, monitor the portal for any further communication. Some notices require a personal hearing — attend it with all your documents.
