GST Notices in 2026 And Exactly How to Reply to Each
Over 1.5 lakh GST notices were issued in just one quarter of FY 2023-24, according to data shared by the GST Council. That's not a small number. And if you're a business owner, CA, or GST practitioner, there's a real chance one lands in your inbox or has already.
A GST notice is not always the start of a legal battle. Sometimes it's a routine check. Sometimes it's a data mismatch. And sometimes, yes, it's serious. The problem is that most taxpayers don't know which is which and that's where the real damage happens.
In my experience working with small businesses and MSMEs, the biggest mistake I see isn't missing a payment. It's ignoring the notice or replying incorrectly. One wrong move, and a routine scrutiny turns into a demand order.
This guide covers all 10 major types of GST notices you'll encounter in 2026 what they mean, why they're issued, and exactly how to respond. No jargon dumps. Just what you actually need to know.
What Is a GST Notice and Why Should You Take It Seriously?
A GST notice is a formal communication from a GST officer requiring a response or explanation from a taxpayer. It works by triggering a mandatory reply window usually 7 to 30 days. Most commonly used for scrutiny, demand, or registration issues. Over 1.5 lakh notices were issued in Q3 FY2023-24 alone.
Here's the thing. A lot of business owners see a GST notice and assume it's a mistake or something minor. They push it aside. Three weeks later, they've missed the reply deadline and now they're looking at an ex-parte assessment order.
Under Section 169 of the CGST Act, a notice is legally served the moment it's uploaded to your GST portal. You don't have to receive a physical letter. The clock starts ticking from that day.
So what does this mean for you? Log into your GST portal regularly. Check the 'Notices / Orders / Demands' section. Don't wait for a physical document to arrive. (I've met taxpayers who had demand orders issued against them and still didn't know because they never checked the portal.)
Worth knowing: Missing a reply deadline almost always results in an unfavourable assessment, regardless of whether you actually owe anything.
Types of GST Notices – At a Glance
Before getting into each type, here's a comparison table that shows all major GST notice forms, who issues them, your response window, and the most common reason they're triggered.
The 10 Most Common GST Notices in 2026 – And How to Handle Each
Type 1: Show Cause Notice (SCN) – Form DRC-01
This is the most serious notice you can receive. A DRC-01 is issued when a GST officer believes tax has been short-paid, not paid, wrongly claimed as a refund, or evaded. Before a demand order can be passed, the officer must issue an SCN and give you a chance to explain.
You typically get 30 days to reply. Do not ignore this. In my view, skipping this step is the single biggest risk a taxpayer can take because a missed SCN reply almost always results in a demand order plus interest plus penalties.
Practical tip: Reply via Form DRC-06 on the GST portal. Address every point raised in the SCN. If the demand has merit, consider paying the tax under Form DRC-03 to reduce penalty exposure.
Type 2: Scrutiny Notice – Form ASMT-10
This comes when the GST officer spots discrepancies in your returns like a mismatch between GSTR-1 and GSTR-3B, or between your GSTR-2A and what you've claimed as Input Tax Credit (ITC).
You have 15 days to reply using Form ASMT-11. If your explanation is accepted, the matter closes. If not, it moves to assessment proceedings.
Practical tip: Reconcile your GSTR-1, GSTR-3B, and GSTR-2B regularly. If you catch mismatches before the notice arrives, you can often correct them via an amended return.
Type 3: Assessment Notice – Form ASMT-13
If you haven't filed your returns and a best-judgment assessment is being done, you'll receive an ASMT-13. This means the officer is estimating your tax liability based on available data which is rarely in your favour.
Practical tip: File your pending returns immediately. You can apply to set aside an ASMT-13 assessment within 30 days by filing an application in Form ASMT-14 and GST APL-01.
Type 4: Registration Notice – Form REG-17
This notice is issued when the GST officer intends to cancel your registration due to non-compliance, non-filing, or if the business appears to be non-operational. You have 7 days to respond in Form REG-18 and show cause why your registration should not be cancelled.
Practical tip: File all pending returns before replying. A reply without clearing dues is rarely accepted. If your registration has already been cancelled, apply for revocation using Form GST REG-21 within 30 days.
Type 5: Composition Scheme Notice – Form CMP-05
If you're registered under the composition scheme but the officer believes you don't qualify or that you've exceeded the threshold turnover you'll receive a CMP-05. You get 15 days to reply in Form CMP-06.
Practical tip: Keep your annual turnover well-documented. If you've crossed the composition limit mid-year, it's better to voluntarily opt out than wait for a notice.
Type 6: Refund Rejection Notice – Form RFD-08
Filed a refund claim that's been questioned? A RFD-08 is a notice of deficiency or proposed rejection. You get 15 days to clarify or submit additional documents in Form RFD-09.
Practical tip: Always attach supporting documents with your original refund claim. A missing invoice or shipping bill is one of the top reasons RFD-08 notices are triggered.
Type 7: ITC Mismatch Notice (GSTR-2A vs GSTR-3B)
This isn't always a formal notice, sometimes it's a letter or advisory but it has serious implications. When what you've claimed as ITC in
GSTR-3B doesn't match what's showing in your GSTR-2A or
GSTR-2B, the department takes note.
Practical tip: Run a monthly ITC reconciliation. Tools like the GSTN's own comparison reports can flag mismatches early. Reverse excess ITC voluntarily via DRC-03 before you get a formal notice.
Type 8: E-Way Bill Violation Notice
If goods in transit are found without a valid e-way bill or with an expired one the officer can issue a detention notice and demand tax plus a 100% penalty. This is one of the most operationally disruptive notices a business can face.
Practical tip: Ensure your logistics team generates e-way bills before the consignment leaves. Set up auto-alerts for expiry if your shipments are frequently delayed in transit.
Type 9: Anti-Profiteering Notice
Since GST reduced the tax burden on many goods, the National Anti-Profiteering Authority (NAA) was set up to ensure businesses passed on the benefit to consumers. If they believe you haven't, you can receive a notice requiring explanation.
Practical tip: Document any price changes you made at the time of GST rate revisions. If you reduce prices, keep the pricing data and communication ready.
Type 10: Audit Notice – Form ADT-01
The GST department conducts audits under Section 65 of the
CGST Act. You'll receive Form ADT-01 with at least 15 days' notice before the audit begins. The auditors will examine your books, invoices, returns, and records.
Practical tip: Don't wait for an audit to organise your records. A well-maintained file of purchase invoices, bank statements, and export documents makes the entire process smoother and limits adverse findings.
Real Case Study: How a Delhi MSME Turned an SCN Around
A wholesale textile trader in Delhi with an annual turnover of Rs 3.2 crore received a DRC-01 notice in February 2024. The demand was Rs 18.4 lakh based on an alleged ITC mismatch between GSTR-3B and GSTR-2B across 14 months.
The owner's first instinct was to panic. His CA advised him to step back and systematically reconcile every invoice. After a 6-day reconciliation exercise, they found Rs 11.2 lakh of the demand was legitimate but Rs 7.2 lakh was due to supplier filing delays (the suppliers had filed GSTR-1 after the due date, so the ITC didn't appear in GSTR-2B on time).
They filed a detailed reply via DRC-06, paid the Rs 11.2 lakh voluntarily under DRC-03 (which reduced the penalty), and submitted supplier-side proof for the remaining Rs 7.2 lakh. The demand was reduced to zero on the Rs 7.2 lakh portion within 60 days.
The lesson? Panic doesn't help. Documentation does. And paying what's genuinely owed while fighting what isn't is usually the smartest approach.
What Tax Experts Say About GST Notices
The GST Council and CBIC have consistently emphasised that notices should not be treated as adversarial they're part of a compliance-verification mechanism. That said, how you respond matters enormously.
"Taxpayers must ensure that their reply to any SCN is factual, supported by documentary evidence, and filed within the stipulated time. A well-structured reply can often lead to dropping of charges even where there appears to be a discrepancy." – ICAI Guidance Note on GST Litigation, Institute of Chartered Accountants of India, 2023
Honestly, most guides overcomplicate this. The ICAI's point is simple: facts plus documents plus timing. If you have those three things, you're in a strong position. If you're missing any one of them, your risk goes up significantly.

Conclusion
Start with this: 1.5 lakh notices in a single quarter. These are not rare events. They happen to real businesses, small ones, well-run ones, honest ones because GST compliance has a lot of moving parts and the system flags mismatches automatically.
The three things worth taking away from this guide: check your
GST portal regularly, reply within the deadline, and keep your invoices and reconciliations in order. Most GST notices can be addressed or avoided entirely if you stay on top of your compliance.
GST notices are not the end of the world. They're a process. And like any process, understanding how it works puts you in control.
