If your company operates across multiple states, you already know the feeling — a notice lands on one GSTIN, and suddenly three people are scrambling through emails, portals, and ERP exports to figure out what happened and when the deadline is.
That's the reality of GST notice management for enterprises in India right now. GSTN is actively scrutinising over 1.51 crore active registrations using risk-based automated matching. For businesses with 20, 50, or 100+ GSTINs, the exposure isn't just operational — it's financial. Missed replies mean demand orders. Demand orders mean bank attachments.
This guide is for the tax teams actually sitting with this problem every day.
Not all GST notices carry the same weight. Treating them the same way is one of the fastest ways to escalate a manageable scrutiny into a formal adjudication.
Here's what each notice means, what triggers it, and what you have to file back:

One update that many teams haven't fully absorbed yet: from FY 2024-25 onwards, DRC-01 is issued under Section 74A — replacing the older Sec 73/74 distinction. The notice must now be served within 42 months of the annual return due date. Penalty slabs are still tiered based on intent and the stage at which payment is made.
Here's something the GST framework doesn't make easy — every GSTIN is treated as a distinct person under the CGST Act. There is no concept of PAN-level consolidation at the department's end. Each GSTIN has its own notice calendar, its own ITC reconciliation requirement, its own filing obligation.
For a company with 30 GSTINs across 15 states, that's 30 separate compliance tracks running in parallel. Each one capable of generating its own ASMT-10, its own DRC-01, its own audit notice — simultaneously.
The volume isn't the only problem. GSTN's automated matching engine runs comparisons across GSTR-1/3B, GST turnover vs ITR data, GSTR-3B vs GSTR-2B, and e-way bill records. Any mismatch in any of these — across any GSTIN — can trigger a notice. Teams that are manually logging into 30 portals are not catching these early enough.
ASMT-10: Scrutiny Notice
ASMT-10 is not a demand. It's a question. The department has spotted a discrepancy and wants an explanation before escalating.
Step 1 — Read it carefully. Identify the GSTIN, the tax period, and the specific mismatch flagged — whether it's a GSTR-1 output discrepancy or an ITC mismatch in GSTR-3B vs GSTR-2B.
Step 2 — Reconcile. Pull GSTR-1, GSTR-3B, and GSTR-2B for that period. Check for credit and debit notes that may not yet be visible on the GSTN portal.
Step 3 — Take a position. If the difference is legitimate, pay via DRC-03. If you're disputing it, prepare a written reconciliation with every supporting document attached.
Step 4 — File ASMT-11 within 30 days (extendable to 45). If the department accepts it, proceedings close. If rejected, it escalates to DRC-01.
Missing this window is how a reconciliation issue becomes a Show Cause Notice.
This is formal adjudication territory. The tone of your response here matters.
Assess the demand first. Note the tax period, sections cited, and the total demand broken into principal, interest, and penalty. Confirm whether it's under Sec 73/74 (pre-FY25) or Sec 74A (FY25 onwards).
Use voluntary payment strategically. At the DRC-01A stage, the penalty is fully waivable. Even at DRC-01, paying within 30 days significantly reduces the total exposure.
Prepare your DRC-06 reply with reconciliations, invoices, payment evidence, and legal references. Pay any partial liability via DRC-03 to demonstrate good faith.
If DRC-07 is issued — meaning a demand order has been passed — you're in appeal territory. File APL-01 within 3 months. The pre-deposit requirement: 100% of admitted tax plus 10% of disputed tax (capped at ₹20 Cr for CGST/SGST, ₹40 Cr for IGST). As of May 2025, the Supreme Court in Yasho Industries confirmed that the 10% pre-deposit can be paid from the Electronic Credit Ledger.
For GSTAT appeals under Sec 112, the rate remains 10% — reduced from 20% under the Finance Act 2024.
Simpler in concept, but still time-sensitive. Check which return — GSTR-1 or GSTR-3B — is pending for the flagged GSTIN, and file it within 15 days. Filing the pending return automatically closes the notice. The risk here is volume: in a multi-GSTIN setup, a GSTR-3A on a dormant or low-activity GSTIN can sit undetected for days.
Here's where things get honest.
Spreadsheet tracking works when you have three GSTINs and a dedicated person watching them. With 20+ GSTINs, it doesn't just become inconvenient — it becomes a liability.

The 30-day deadline on a DRC-01 is not negotiable. An unanswered SCN becomes a DRC-07 demand order — and that opens the door to bank attachment and asset seizure. No team wants to explain that to a CFO.
If you're evaluating tools for multi-GSTIN compliance, there are a few things that aren't optional.
PAN-level visibility with GSTIN drill-down. Tax heads and CFOs need a consolidated view. Operations teams need the GSTIN-level detail underneath it.
Auto GSTN sync. One-click download of all new notices, organised into cases by form, reference ID, and status — not sitting in someone's email.
Deadline escalation with overdue alerts. Not just reminders. Actual escalation workflows that don't depend on a single person being available.
AI-powered ITC reconciliation. The kind that runs GSTR-2B vs your purchase register automatically — and catches the mismatches that would have triggered an ASMT-10 before the notice is ever issued.
Full audit trail. Every notice, every reply, every attachment, every timestamp — in a single reverse-chronological case log.
Leadership dashboard. Real-time view of demand at risk, overdue cases, and time-critical notices for whoever is accountable at the top.
Legaldev's Notice Tracker within the Legaldev Compliance Cloud is built around exactly these requirements. It handles PAN- and GSTIN-level notice consolidation, integrates directly with GSTN, and its AI-powered ITC reconciliation engine — ClearGST — processes 6,000 invoices per second. Across 3,500+ Indian companies, it's recovered 3–5% of working capital tied up in ITC inaccuracies.
Over 5,000 enterprises in India are already using Legaldev for this. For teams managing 10+ GSTINs, it replaces a disconnected collection of portals, spreadsheets, and email threads with a single workflow.
Where This Is All Headed
The GSTN scrutiny universe covers 1.51 crore+ active registrations. GST collections for FY 2024-25 crossed ₹22.08 lakh crore. The department's automated matching systems are only getting more sophisticated — and more aggressive.
Enterprises that are still handling notices reactively — case by case, person by person — are already behind. The ones running structured workflows, monthly reconciliations, and centralised automation are catching issues before notices are issued. That's the difference between managing compliance and being managed by it.
The penalties, the ITC reversals, the adjudication risk — all of it is avoidable. But only if the system is in place before the notice lands.
A: ASMT-10 is a scrutiny notice — it flags a discrepancy in your filed returns and asks for an explanation. It is not a demand. DRC-01 is a Show Cause Notice issued when the department moves toward formal adjudication. If your ASMT-11 reply is rejected, the matter escalates to DRC-01. An unaddressed DRC-01 results in a DRC-07 demand order, which carries recovery consequences including bank attachment.
A: The only practical approach at that volume is a centralised notice management system with auto GSTN sync. Each GSTIN must have an assigned owner, and internal submission deadlines should be set 7–10 days ahead of the statutory ones. Monthly GSTR-2B reconciliation is essential to catch mismatches before they trigger an ASMT-10.
A: An unanswered DRC-01 automatically progresses to a DRC-07 demand order. Once a demand order is issued, the department can initiate recovery — including bank account attachment and asset seizure. Filing APL-01 for a first appeal requires a pre-deposit of 100% admitted tax plus 10% of disputed tax.
A: For a First Appeal under Section 107, the requirement is 100% of admitted tax plus 10% of disputed tax — capped at ₹20 Cr for CGST/SGST and ₹40 Cr for IGST. For GSTAT appeals under Section 112, the same 10% rate applies, reduced from 20% under the Finance Act 2024. The Supreme Court's May 2025 ruling in Yasho Industries confirmed that this 10% can be paid from the Electronic Credit Ledger.
A: From FY 2024-25, DRC-01 is issued under the unified Section 74A — replacing the earlier bifurcation between Sec 73 (non-fraud) and Sec 74 (fraud/suppression). The notice must be served within 42 months of the annual return due date. Penalty slabs remain tiered based on intent and the stage at which voluntary payment is made.
A: Non-negotiables are: multi-GSTIN tracking with PAN-level consolidated view, automatic GSTN sync, end-to-end case management with full audit trail, deadline escalation with overdue alerts, offline notice upload capability, and a reconciliation engine that compares GSTR-2B against your purchase register before notices are issued — not after.
A: Yes — GSTR-2B vs GSTR-3B mismatches are one of the primary ASMT-10 triggers under GSTN's automated matching engine. If your purchase register doesn't match what's showing in GSTR-2B, the department flags it. Running monthly ITC reconciliation as a preventive process — rather than waiting for a notice — is the only way to stay ahead of this.
A: Without automation, a single DRC-01 response for one GSTIN can take 5–10 working days of internal effort — pulling ERP data, matching invoices, drafting replies, and getting sign-offs. With a notice management system that auto-links documents to notice periods and uses pre-populated templates, the same response can be turned around in hours. The 30-day window sounds long until you're managing eight of them simultaneously.
A: GSTN assigns a risk score to each taxpayer based on filing behaviour, ITC claims, return discrepancies, and e-way bill patterns. A high risk score increases the likelihood of ASMT-10 triggers and department audit selection under ADT-02. Persistent defaults — missed filings, unresolved notices — can also lead to GSTIN suspension, which has cascading effects on business operations and vendor credibility.
A: Yes — it's specifically built for that use case. The system consolidates all GST, ITR, and TDS notices across all GSTINs under a single PAN-level view, with drill-down to the GSTIN level. For CFOs and tax heads, the leadership dashboard provides real-time visibility into overdue cases and demand at risk across every state registration, without requiring individual portal logins.
