GST Scrutiny Notice ASMT-10: How to Reply in ASMT-11 Before It Becomes a Demand

There is a message on your GST dashboard you have never seen before: a notice in Form ASMT-10, saying your returns don't add up. First, breathe. An ASMT-10 is a question, not a bill.

The short answer: ASMT-10 is a scrutiny notice under Section 61 of the CGST Act (Rule 99), asking you to explain discrepancies between your filed returns within 30 days of service. You reply in Form ASMT-11 — accepting the discrepancy and paying the shortfall with interest via DRC-03, or contesting it with documents. A satisfactory reply ends the case in Form ASMT-12.

What you do in the next 30 days decides whether this dies quietly or turns into a tax demand. This is the playbook for the quiet outcome.

What an ASMT-10 actually is (and what it isn't)

Section 61 lets the proper officer scrutinise your returns against everything already on record — GSTR-1, GSTR-3B, GSTR-2B, e-way bills, e-invoices, even your annual GSTR-9. If something doesn't match, Rule 99 says the officer must tell you in Form GST ASMT-10, listing each discrepancy with the tax, interest and other amounts quantified.

The 30-day clock

Rule 99 gives you up to 30 days from service of the notice, "or such further period as may be permitted" by the officer. You can ask for more time — before the deadline expires, in writing on the portal. Extensions are discretionary, not guaranteed.

One practical warning: ASMT-10 is served electronically; no physical copy is required. A stale email address on your registration has genuinely cost people their 30 days. Check the notices tab today.

Question or charge? The analogy that makes this click

Your bank calling about a card transaction that doesn't fit your pattern — "was this you?" That's the ASMT-10. The bank freezing your account and filing a fraud case — that's the DRC-01 show cause notice. Same data trail, completely different stage.

A clear, reconciled, document-backed ASMT-11 often ends the proceeding here with an ASMT-12 closure. A vague reply — or accepting in words but never paying — does the opposite: your own filing becomes the department's starting evidence for a demand.

The first decision: pay it or contest it?

Every discrepancy in the notice gets one of two answers.

Accept. The officer is right. Pay the tax shortfall plus interest through Form DRC-03 before you file the reply, then say so in ASMT-11 and attach the payment challan. DRC-03 is the portal's voluntary-payment form — it exists exactly for this.

Contest. The mismatch is explainable — a timing difference, a reversal already made, an error in the officer's comparison. Explain point-wise in ASMT-11 and attach the proof. Words alone never win.

Why pay first? From FY 2024-25, all GST demands fall under Section 74A, the unified provision replacing Sections 73 and 74 for newer periods. Under 74A, in non-fraud cases: pay tax plus interest before a show cause notice is issued and no penalty is payable at all — no notice is even served. Pay within 60 days of the SCN, and still no penalty. Penalty lands only at adjudication: 10% of the tax or ₹10,000, whichever is higher.

One trap: Section 74A(11). If the shortfall is self-assessed tax, or tax you collected on invoices but didn't deposit within 30 days of its due date, the 10%-or-₹10,000 penalty applies even if you pay early. The zero-penalty window doesn't cover "I billed GST and kept it."

The five discrepancies that trigger most ASMT-10s

1. ITC in GSTR-3B higher than GSTR-2B. The biggest single cause — usually a supplier who filed GSTR-1 late, or a wrong claim. Timing? Explain with evidence. Wrong claim? DRC-03 it.

2. GSTR-1 vs GSTR-3B turnover mismatch. Most often a reporting error; sometimes unreported sales. Reconcile invoice-wise.

3. Reverse charge not paid or disclosed. Imported services, GTA freight, legal fees. Compute RCM from your expense ledger.

4. Ineligible ITC. Blocked credits (motor vehicles, food, works contracts), personal use, inputs for exempt supplies. Reverse in 3B and show the working.

5. E-way bill turnover vs return turnover. Goods moved without matching invoices. Reconcile e-way data with your sales register before the officer does.

Timing helps FY 2025-26 filers: GSTR-9 opened for filing on 10 October 2026 and is due 31 December 2026. Discrepancies fixed in your GSTR-9 reconciliation are discrepancies the officer has less reason to question.

A worked example: what silence costs vs what a reply costs

Say your GSTR-1 for a month shows ₹42,00,000 of outward supplies, and your GSTR-3B shows ₹40,00,000. The ASMT-10 flags ₹2,00,000 of unreported turnover. At 18%, the shortfall is ₹36,000.

Path A: accept in ASMT-11, pay ₹36,000 plus interest via DRC-03, attach the challan. Under Section 74A the matter ends with zero penalty.

Path B: ignore the notice. The officer issues a DRC-01. You scramble and pay within 60 days of that SCN — still no penalty, but you've lost weeks and earned a case number.

Path C: fight through adjudication and lose. Tax ₹36,000, interest, plus 10% penalty = ₹3,600 — except the floor: 10% of tax or ₹10,000, whichever is higher. Your penalty is ₹10,000, nearly a third of the tax itself.

Same ₹36,000 dispute. ₹0 penalty vs ₹10,000 penalty. That is the price of a bad answer.

Filing the ASMT-11

On www.gst.gov.in: Services → User Services → View Additional Notices/Orders. Then: (1) answer each mismatch point-wise; (2) reconcile every discrepancy against your books; (3) pay accepted liabilities in DRC-03 first; (4) draft the explanation — what was flagged, what your books show, why the difference exists, what action you took; (5) attach one organised PDF with annexures; (6) review the figures; (7) submit within 30 days and save the acknowledgment number; (8) track the case status.

Professional help pays for itself here — our GST notice reply service drafts exactly these responses. A wrong reply becomes evidence; a careful one becomes a closed case.

Three mistakes that turn a question into a demand

1. No reply at all. Rule 99(2) lets the officer move to audit (Sections 65/66), inspection (Section 67), or a demand under Section 74A when no satisfactory explanation arrives in time.

2. The one-line reply. "All ITC is genuine" without a reconciliation is treated as no reply with words.

3. Accepting in words, paying never. The officer checks whether the money landed. An unpaid acceptance becomes the foundation of the demand.

What happens after you reply

Best case: the officer accepts your reply and closes the proceeding in Form ASMT-12. This is where most well-answered ASMT-10s end.

If the discrepancy survives, the ladder runs: DRC-01A (pre-SCN intimation — a settlement window), then DRC-01 (the formal show cause notice; reply in DRC-06), personal hearing, DRC-07 (the order — the demand becomes recoverable), and appeal within 3 months. One nuance: scrutiny and demand are separate tracks in law, but in practice the ASMT-10 is usually the first step. Getting your returns right, as our GST return filing guide explains, is the cheapest way to never climb this ladder.

The ASMT-10 is the department at its most reasonable: asking before demanding. Answer like the case matters — because it decides whether one ever begins.

Frequently asked questions

Is an ASMT-10 a demand I have to pay?
No — a request for explanation under Section 61. Ignored or answered badly, it becomes the opening move of a demand under Section 74A.

Can I reply after 30 days?
Request an extension before the deadline expires, in writing on the portal. Approval is discretionary — don't count on it after the fact.

Can I accept part of the notice and contest the rest?
Yes — this is normal. Pay the accepted part via DRC-03, disclose it, and contest the rest point-wise with documents.

I already filed GSTR-9 for that year. Does it help?
Yes. Attach the reconciliation — it shows your annual position matches your monthly filings.

Will a detailed reply invite an audit?
No. Audits and demands flow from unresolved discrepancies, not thorough replies. The risk is a weak reply, not a strong one.
