ASMT-10 Reply — The Scrutiny Notice You Must Not Treat Casually
Quick answer: Reply to ASMT-10 in Form ASMT-11 within 30 days (a 15-day extension can be sought) on the GST portal. Explain each discrepancy in a table with documents attached, or accept and pay via DRC-03 with proof. A satisfactory reply is closed by the officer in ASMT-12.
ASMT-10 is the GST department's scrutiny notice: portal data showed a discrepancy in your returns, and the officer wants your explanation. It looks mild — no demand figure, no drama. But an ignored or weak ASMT-10 response is the most common origin story of a full DRC-01 show cause notice. Handled well, the matter ends with a one-line acceptance order.
How a strong ASMT-11 reply is built
- Decode each discrepancy — the notice lists specific parameters (turnover gap, ITC excess, interest shortfall). Each one gets its own answer; a general paragraph convinces no one.
- Reconcile before responding — GSTR-1 vs 3B line-items, GSTR-2B vs 3B with the purchase register, e-way bill trails. Most "discrepancies" are timing differences, credit notes, or supplier late-filing — provable with tables.
- Choose the honest route per item — defend what is defensible with documents; for genuine slips, pay through DRC-03 and say so. A mixed, honest reply carries far more credibility than blanket denial.
- File ASMT-11 in time, keep the record — the reply, annexures and acknowledgment become your foundation if the matter ever escalates.
We run this exact sequence for clients — reading your notice line by line, doing the GSTR-1/2B/3B reconciliation ourselves, and drafting the ASMT-11 reply with the discrepancy table already built.
The reply format officers actually want
Officers read hundreds of replies; the ones that close fastest use a discrepancy table, not paragraphs:
| Discrepancy alleged | Taxpayer's explanation | Supporting document |
|---|---|---|
| ITC in GSTR-3B exceeds GSTR-2B by ₹__ for period __ | Difference relates to supplier invoices filed late in GSTR-1, now appearing in subsequent 2B; claim within Section 16(4) window | Invoice-wise reconciliation annexure; supplier GSTINs; later 2B extract |
| Turnover in GSTR-1 exceeds GSTR-3B by ₹__ | Credit notes of ₹__ issued in the period, netted in 3B; no short payment | Credit-note register; 3B computation sheet |
| Accepted item (if any) | Inadvertent excess of ₹__; tax with interest deposited | DRC-03 challan dated __ |
Common ASMT-10 triggers we defend weekly: 3B-vs-2B ITC gaps, GSTR-1-vs-3B liability differences, e-way-bill-vs-return mismatches, RCM under-declaration, and ITC from suppliers whose registration was later cancelled. Send us the notice and we'll tell you within the day which of these it is and what the reply needs.
When it escalates anyway
If the officer is unconvinced and a show cause notice follows, the ASMT-11 record shapes the battlefield. Our DRC-01 defence practice takes over seamlessly — same reconciliations, deeper legal submissions, hearing representation. Just received the notice today? Start with the first 48 hours guide.

Frequently Asked Questions
What is the deadline to reply to ASMT-10?
Reply in Form ASMT-11 within the time stated in the notice — commonly 30 days, though some officers specify 15. The date printed on your notice is binding; calendar it the day the notice arrives.
What happens after I file ASMT-11?
If the officer accepts your explanation, proceedings drop with an order in ASMT-12. If not, the matter can escalate to a DRC-01 show cause notice under Section 73/74 — which is why the ASMT-11 must be complete, not casual.
What discrepancies trigger ASMT-10?
Typical triggers: GSTR-1 vs GSTR-3B turnover gaps, GSTR-3B vs GSTR-2B ITC differences, e-way bill vs return mismatches, and interest/late-fee shortfalls — all machine-detected from portal data.
Can I just pay the difference instead of replying?
If the discrepancy is genuine, payment with DRC-03 and a short ASMT-11 noting it can close the matter cleanly. But paying without verification surrenders money on timing differences and supplier delays that a proper reconciliation would have defended.
Is there a fixed penalty for an ASMT-10 notice?
No — ASMT-10 itself carries no fixed penalty; it's an inquiry, not a demand. But an unresolved discrepancy that escalates to a Section 73 or 74 demand can attract 18% annual interest on the unpaid tax plus a penalty ranging from 10% to 100%, depending on whether it's treated as a genuine error or deliberate suppression. Replying properly at the ASMT-10 stage is what avoids that escalation.
What if I can't reply to ASMT-10 within 30 days?
Write to the officer requesting an extension before the deadline passes — this is usually granted for a genuine reason. An unanswered ASMT-10 doesn't just expire quietly; it typically escalates to audit, inspection, or a formal DRC-01 demand notice.
Should I keep filing my GST returns while an ASMT-10 is pending?
Yes — continue filing GSTR-1 and GSTR-3B on schedule regardless of the pending scrutiny. Stopping return filing during an active ASMT-10 adds a separate compliance problem on top of the one you're already resolving, and can itself trigger further departmental action.
