Scrutiny of GST Returns Support Services

Scrutiny of GST Returns is the first formal point of contact between a taxpayer and the department on the accuracy of their self-assessed returns. It is carried out by the proper officer under Section 61 of the CGST Act, 2017 read with Rule 99 of the CGST Rules, and operationalised through CBIC instructions and the standard operating procedure laid down by Instruction No. 02/2022-GST and subsequent guidelines. Where discrepancies are noticed — typically in GSTR-1 vs GSTR-3B, GSTR-2B vs GSTR-3B, RCM declarations, interest under Section 50, or turnover / ITC mismatches with e-way bill and GSTR-9 data — the officer issues Form ASMT-10 asking the taxpayer to explain the variance within 30 days (extendable).

Scrutiny is meant to be a narrow, issue-specific review — not a full audit. Yet in practice, a weak or delayed response to an ASMT-10 can quickly escalate into a Section 65 audit, a Section 73 / 74 SCN, or a best-judgment assessment. A carefully drafted ASMT-11 reply, backed by proper reconciliations and supporting documents, closes the matter in the most favourable way — with an ASMT-12 order of "no further action". Where the officer is not satisfied, the next stage is audit or assessment, with substantially higher rupee and procedural exposure. In that sense, ASMT-10 is not just a notice; it is the final, quiet opportunity to resolve an issue before it formally becomes a demand.

We offer end-to-end Scrutiny of GST Returns Support — from health-check of your GST returns before any notice is received, interpretation of the specific parameters flagged in ASMT-10, preparation of issue-wise reconciliations for every variance, drafting of the ASMT-11 reply with legal arguments and documentary support, voluntary discharge of any shortfall through DRC-03 where appropriate, representation before the proper officer, and closure through ASMT-12 — so that a scrutiny notice ends at the scrutiny stage itself, without escalating into an audit, SCN, or demand order.

FAQs on Scrutiny of GST Returns

What exactly is scrutiny of GST returns under Section 61?
Scrutiny of returns under Section 61 of the CGST Act, 2017 read with Rule 99 of the CGST Rules is a limited-scope review conducted by the proper officer to verify the correctness of the self-assessed GST returns filed by a taxpayer. Where the officer notices discrepancies — typically identified through GSTN analytics and data-matching across GSTR-1, GSTR-3B, GSTR-2B, e-way bills, e-invoices, and GSTR-9 — a notice in Form ASMT-10 is issued seeking an explanation. The objective is to close smaller, explainable issues at the return-review level itself, without triggering a full-blown audit or demand proceeding.
How much time do we have to reply to ASMT-10?
The standard time period to file a reply in Form ASMT-11 is 30 days from the date of service of the ASMT-10 notice, or such further period as may be allowed by the proper officer. In practice, a short extension request — made well before the original deadline — is routinely granted where a large volume of reconciliation is involved. What matters is that the reply, when filed, is complete and persuasive; piecemeal replies tend to invite follow-up questions and shift the matter closer to audit or SCN stage.
What happens if we do not respond to ASMT-10?
Non-response or inadequate response to an ASMT-10 is one of the clearest triggers for escalation. Under Section 61(3), where the taxpayer fails to furnish a satisfactory explanation within the prescribed time or does not take corrective action, the proper officer may proceed to take action under Section 65 (audit), Section 66 (special audit), Section 67 (inspection / search), or Sections 73 / 74 (demand proceedings). The same issues that could have been settled with a clean ASMT-11 and, where needed, a small DRC-03 payment can suddenly become full-blown demands with interest and penalty. Responding carefully and on time is therefore central to the whole strategy.
Is scrutiny the same as a GST audit?
No, they are distinct proceedings. Scrutiny under Section 61 is a limited review focused on specific discrepancies in the returns, primarily document-based and usually handled through the GST portal. A GST audit under Section 65 is a much wider, full-scope examination of the taxpayer's books, records, and business activity, typically with onsite interaction between the audit team and the taxpayer, and concluded through ADT-02 findings. Scrutiny often precedes audit — poorly handled scrutiny almost always increases the likelihood of an audit being initiated subsequently.
Can we pay tax voluntarily during scrutiny to close the matter?
Yes. Where the taxpayer accepts that a particular discrepancy reflects a genuine shortfall — missed RCM, small ITC mismatch, interest shortfall — voluntary payment of tax along with applicable interest through Form DRC-03 is often the cleanest way to close the issue. This is acknowledged in the ASMT-11 reply and typically leads to ASMT-12 closure on that point. For issues with real legal merit, paying is not required; instead, the reply focuses on reconciliation, legal submissions, and supporting evidence. We evaluate each flagged item individually and recommend the most commercially and legally sound route.
What is ASMT-12 and why does it matter?
ASMT-12 is the closure order issued by the proper officer under Rule 99(3) of the CGST Rules when, on receipt of the ASMT-11 reply (or on voluntary payment by the taxpayer), the officer is satisfied that no further action is warranted on the discrepancies flagged in the ASMT-10. It is the most favourable outcome at this stage — it formally closes the scrutiny on those issues for the relevant period. Obtaining ASMT-12 protects the taxpayer against the same issues being reopened casually, although the department retains its power to initiate audit or assessment where fresh material comes to light.
How do DRC-01B / DRC-01C fit into the scrutiny process?
DRC-01B (under Rule 88C) and DRC-01C (under Rule 88D) are system-generated intimations for specific mismatches — GSTR-1 vs 3B tax liability and GSTR-2B vs 3B ITC respectively. While these are technically separate from a Section 61 ASMT-10 scrutiny, the issues they flag often feed directly into subsequent scrutiny notices. In practice, the taxpayer should treat DRC-01B / 01C as an early-warning signal and use them as an opportunity to fix the underlying mismatch or pay the differential voluntarily, before the same issue reappears in a full-blown ASMT-10 or audit.
Can the same period be scrutinised more than once?
The scheme of Section 61 envisages scrutiny as a one-time review of the specific discrepancies flagged in an ASMT-10 for a given period. Once ASMT-12 is issued, those issues stand closed. However, the department retains the ability to initiate audit under Section 65, special audit under Section 66, or demand proceedings under Sections 73 / 74 on the same period if fresh or different issues come to light, subject to the statutory limitation periods. Good practice is therefore to treat the scrutiny reply as the primary record that will be relied on in any later proceeding — and to keep the working papers for at least the statutory record-retention period.
