ASMT-10 is a GST Scrutiny Notice issued when the department detects discrepancies in your filed returns. Typically triggered by GSTR-1 vs GSTR-3B mismatch or turnover differences. Our AI analyses the specific discrepancies and drafts a reconciliation-based response with proper legal backing.
GST Form ASMT-10 is a Scrutiny Notice issued by the Proper Officer under Section 61 of the Central Goods and Services Tax (CGST) Act, 2017, read with Rule 99 of the CGST Rules. It is issued when the officer, during examination of the returns and related documents, finds discrepancies that require explanation from the taxpayer.
Unlike DRC-01 which is a formal demand notice, ASMT-10 is an inquiry notice — it seeks your explanation for identified discrepancies. Common triggers include mismatch between outward supplies declared in GSTR-1 and tax liability discharged in GSTR-3B, differences between GSTR-3B and GSTR-2A/2B, HSN-level discrepancies, and turnover variances when cross-referenced with income tax returns or e-way bill data.
The importance of ASMT-10 cannot be overstated: a satisfactory response leads to closure of the scrutiny with no further action. An unsatisfactory response, however, may escalate to formal proceedings under Section 73 or 74, resulting in a DRC-01 Show Cause Notice. This makes the ASMT-10 response your best opportunity to resolve the matter at the earliest stage.

GSTR-1 vs GSTR-3B Turnover Mismatch
Outward supply value in GSTR-1 differs from the taxable value reported in GSTR-3B. This is the single most common trigger, often due to timing differences in reporting amendments and credit/debit notes.
ITC Claimed Exceeds GSTR-2A/2B
Input Tax Credit availed in GSTR-3B is higher than what appears in auto-populated GSTR-2A or GSTR-2B. Usually caused by delayed filing by suppliers.
E-Way Bill Data vs Return Data Discrepancy
Value of goods moved as per e-way bills generated does not match the outward supply value reported in GSTR-1. Department cross-references these databases routinely.
Income Tax Return vs GST Return Mismatch
Revenue declared in income tax returns (ITR) does not tally with GST turnover. Cross-referencing between CBDT and CBIC data has become automated since 2023.
HSN Summary Mismatch or Missing HSN Codes
HSN-wise summary in GSTR-1 does not reconcile with the main return data, or HSN codes are missing/incorrect. This has become more common since mandatory HSN reporting was enforced from April 2021.
Read the Scrutiny Notice Carefully
Identify the exact discrepancies flagged by the officer. ASMT-10 typically contains a table listing specific differences — GSTR-1 value vs GSTR-3B value, period-wise. Note each discrepancy amount and the periods involved.
Prepare a Detailed Reconciliation
Create a month-wise reconciliation between GSTR-1 outward supplies and GSTR-3B tax liability. Account for amendments filed in subsequent months, credit notes, debit notes, advances received, and any rectifications. This reconciliation is the backbone of your response.
Explain Each Discrepancy
For each flagged item, provide a clear explanation: was it a clerical error (now rectified via amendment), a timing difference (credit note issued in period X but reported in period Y), or a genuine difference that needs additional context? Be specific — vague answers invite escalation.
Gather All Supporting Documents
Attach GSTR-1, GSTR-3B, GSTR-9 (annual return) for the relevant periods. Include credit/debit notes, amendment details, e-way bill summaries, and bank statements if turnover verification is involved. The more documentation, the stronger your response.
