 GST Scrutiny Notice (ASMT-10): What It Really Means & How to Reply Without Panic  

It is common for business owners to feel anxious once they receive a GST Scrutiny Notice (ASMT-10), as they often believe it signifies either a penalty or more serious GST issues.ASMT-10 serves as a notification from the GST Office requesting clarification of discrepancies in reported tax values between filed returns and his/her GSTN data.Most legitimate responses will resolve the issue quickly and without penalty.

What is a GST Scrutiny Notice (ASMT-10)?

ASMT-10 was issued pursuant to Section 61 of the CGST Act of July 2017, and represents an essential component of the routine review of filed returns through the GST Officers' comparative analysis of the information contained in filed returns against data reported via GSTN.

When discrepancies are noted, an ASMT-10 will typically be issued in order to

Request Clarification;

Request Reconciliation;

Allow Voluntary Corrections.

It should be clear that there is no indication that any ASMT-10 will require either a demand or the imposition of a penalty.

What Causes an ASMT-10 to be Issued?

Typically, the most frequently seen reasons behind the issuance of ASMT-10 are discrepancies created as a result of the reporting process between:

GSTR-1 versus GSTR-3B

The same sales may have been reported on several different dates by multiple entities. This can occur as the result of timing issues, adjustments or corrections.

ITC Differences Between Your GSTR-2B and ASMT 10

ITCs are generally reported and matched to your ASMT10 and taken into account prior to being posted on your GSTR2B records or, in the case of unqualified ITC credits, not matched at all.

 ITC Differences Between GSTR-3B and GSTR-2B  

The GST department closely monitors Input Tax Credit (ITC).

ASMT-10 may be issued if:

  • ITC claimed in GSTR-3B exceeds ITC available in GSTR-2B
  • Vendor has not filed returns
  • Supplier filed returns late
  • Ineligible ITC was claimed accidentally

 Sudden Change in Turnover or Tax Liability  

Sudden fluctuations such as:

  • Sharp increase or drop in turnover
  • Significant variation compared to earlier periods

can prompt officers to seek clarification.

Incorrect GST Rate or Classification

Errors in:

  • HSN or SAC codes
  • GST rate selection

may result in underpayment or overpayment of tax, leading to scrutiny.
