A flag is a reason to verify records, not proof that an invoice is fake, tax was evaded or a taxpayer is liable. In India’s GST system, the distinction matters: analytics can help select returns or applications for closer review, while an officer’s scrutiny, the taxpayer’s response and any later formal action are separate steps.
What can GST data analytics detect?
Analytics can compare information held in different records and identify patterns that appear inconsistent or unusual. Official guidance describes these signals as risk indicators used for profiling, scrutiny or verification. They can help direct attention to a transaction or taxpayer; they do not establish what caused a discrepancy or what the final legal outcome should be.

Mismatches between returns and e-way bills
One example identified in GST guidance is a mismatch between transaction details reported in returns and information in e-way bills. Such a difference can prompt a closer look at the underlying supply, reporting period and documents. The mismatch itself does not show whether the issue arose from an error, timing, an amendment or a substantive compliance problem.

Registration details shared across GSTINs
Risk profiling may consider links among registrations. Examples include multiple registrations associated with the same PAN or address, incomplete or incorrect addresses, or common email addresses, mobile numbers, authorised signatories or promoters across GSTINs. These links may be relevant when assessing risk, but a shared identifier alone does not demonstrate that registrations are improper or that a particular supply is fictitious.

Other patterns that may attract verification
The GST e-invoice portal’s guidance on fake invoices also lists sensitive commodities among possible risk indicators. Separately, government descriptions refer to risk-based biometric authentication and physical verification for certain applicants identified as risky, and to risk ratings for refund applications that can help field officers decide where to conduct detailed verification. These examples describe prioritisation and checks, not an automatic finding of fraud.
Official portal guidance also describes routine reports that help a business review its own submitted data. For example, the IRIS IRP analytics help page describes a monthly Sales Overview based on GSTR-1 information and an Errors and Discrepancies report that can be requested for a date range and downloaded. These are taxpayer-facing reporting tools. They should not be confused with officer-facing risk selection or treated as evidence that a business has been flagged for enforcement.
How the signals are used—and what is not publicly established
Government materials describe analytics and risk parameters as tools for identifying or tracking risky registrations, assigning risk ratings to some registration and refund applications, and selecting returns for scrutiny. In its description of CBIC’s Automated Return Scrutiny Module, the GST Council newsletter says the module enables officers to scrutinise returns of Centre-administered taxpayers selected on the basis of data analytics and risks identified by the system. In that workflow, system-identified risks are presented as discrepancies for officers to review.
The public materials covered here do not set out a complete list of system inputs, the weight given to each indicator, the scoring formula, the thresholds for a flag or model performance measures such as false-positive rates. It is therefore not possible to infer from a public description how a particular score was calculated, or to treat a score as a measured probability that a taxpayer has done something wrong. Descriptions of risk-based checks establish that prioritisation is used in the systems discussed; they do not disclose a complete technical account of how those systems decide which cases to select.

Two different meanings of GST analytics
| Use | What it can show | What it does not establish by itself |
|---|---|---|
| Business-facing portal reports | Sales summaries based on GSTR-1 information and errors or discrepancies for a selected date range, as described by the IRIS IRP help page. | That an officer has selected the business for scrutiny, or that a reported difference is fraud. |
| Officer-facing risk selection and verification | Patterns or discrepancies that may help officers decide which returns, registrations or refund applications to examine more closely. | That the selected taxpayer committed fraud, that a specific supply was fictitious, or that a legal liability has been finally determined. |
The IRIS IRP help page describes portal changes during 2025 and 2026, so its exact functions and labels may change. Use the live portal instructions for current navigation rather than assuming that a report or screen will always appear in the same place.
Does a suspicious transaction prove fraud?
No. An alert, risk rating, mismatch or selection for verification is not, on its own, proof of a fake invoice, an intention to evade tax or a taxpayer’s liability. Similar-looking records can have different explanations: a data-entry error, a difference in reporting periods, an amended return, a credit or debit note, a genuine commercial arrangement or a substantive compliance issue. The signal identifies something to examine; the records and the explanation provide context.
This is not just a caution about interpreting data. The procedures described in the CGST Rules distinguish scrutiny or audit from later findings and action. A discrepancy has to be communicated and considered through the applicable process. The fact that an officer or system has identified a point for review should not be represented as a final determination.
What happens after a return is selected for scrutiny?
The return-scrutiny procedure described by CBIC begins with examination of the return against information available to the officer. If the officer identifies a discrepancy, FORM GST ASMT-10 communicates it and seeks an explanation. The taxpayer may accept the discrepancy and pay, or submit an explanation through FORM GST ASMT-11. If the officer finds the explanation acceptable, the taxpayer is informed through FORM GST ASMT-12.
- Review the communication. Check which return, tax period and discrepancy the notice identifies, and follow the stated method and deadline for response.
- Compare the underlying records. Match the relevant invoice and return entries against e-way bill details where applicable, amendments, credit or debit notes and the reporting period.
- Respond through the stated channel. If the explanation is requested through ASMT-11, provide a clear account supported by the records relevant to the identified difference. If the discrepancy is accepted, follow the communication’s instructions about payment or other action.
- Keep the outcome and supporting trail. Retain the notice, response, documents and any acknowledgement or later communication. The officer may accept the explanation or take a further step under the applicable procedure.
The GST Council newsletter’s account of the automated scrutiny module says selected returns display discrepancies for officers and that taxpayers can respond through the common portal. After considering the reply, an officer may accept it or take a further step such as a show-cause notice, audit or investigation. Those are distinct stages; a system flag is not itself any one of them.
How is audit different from a scrutiny flag?
Audit is a separate procedure, not another name for an analytics alert. The CGST Rules describe notice, verification of books and returns, possible communication of discrepancies, consideration of the taxpayer’s reply and communication of audit findings. Audit work may involve examining records beyond the particular difference that first drew attention. A discrepancy can therefore lead to questions or further review, but the audit process still includes an opportunity to consider the taxpayer’s response before findings are communicated.
If a formal communication arrives, verify it through the official channel and use the procedure and deadline stated in that communication. The applicable route can depend on the kind of proceeding and notice; an analytics indicator alone does not tell a taxpayer which legal procedure applies. For a case-specific response, a qualified GST professional can assess the records and the notice.
What do reported fake-ITC case counts tell us?
A Government of India release reported that Central Tax formations under CBIC detected 9,190 fake input tax credit (ITC) cases involving ₹36,374 crore in FY 2023–24. The same release listed 5,966 cases for FY 2021–22 and 7,231 for FY 2022–23. These are government-reported detection counts for those financial years and that scope.

The figures are not counts of initial analytics alerts, final convictions or proven cases of taxpayer guilt in a judicial sense. They also do not show how many alerts were false positives, how many taxpayers were examined in total or the chance that any individual flagged transaction is fraudulent. Without those denominators and performance measures, case counts cannot establish model accuracy or a population-wide probability of guilt.

Start with the specific transaction and period named in a report or communication. Reconcile the source documents before deciding what the discrepancy means; do not assume that one screen or report contains the full history.
- Compare the original invoice with the corresponding GSTR-1 and GSTR-3B entries.
- Where relevant, check the e-way bill details against the invoice and the reported transaction.
- Check whether an amendment or credit or debit note changed the information after the original filing.
- Confirm that the documents and return entries relate to the same reporting period.
- Keep evidence of any correction and copies of communications about the difference.
A self-service errors report can help locate information that needs review, but it does not replace examination of source documents. If you receive a formal notice, respond to the discrepancy it actually identifies rather than trying to guess at an undisclosed risk score. A journalist or reader describing another taxpayer’s case should likewise distinguish an allegation, a risk-based selection, a communicated discrepancy and a formal finding.
Why one audit example should not be generalized
The Comptroller and Auditor General of India’s Haryana GST Compliance Audit, Report No. 2 of 2026, describes a specific audit exercise in which the department responded to 339 of 687 high-value inconsistencies identified by audit; 196 of the responses were characterized as compliance deviations. The report also describes different subsequent actions, including recovery, notices and communication of discrepancies.

Those figures illustrate how identified inconsistencies can lead to different administrative follow-up. They concern that particular Haryana audit exercise, not a national sample of GST analytics alerts. They do not measure the accuracy of an analytics model or establish what happens to every discrepancy identified elsewhere.
What the evidence supports—and where it stops
Official descriptions support a practical conclusion: GST data analytics can surface patterns such as return and e-way bill mismatches, linked registration details and other risk indicators, and can help authorities prioritise scrutiny or verification. Public portal reports can also help businesses inspect their submitted information. In each setting, the signal is a prompt to examine records, not a substitute for that examination.
The published descriptions do not provide a full scoring method or false-positive rate. Nor do they make every anomaly conclusive. A reliable account of a GST case should identify the stage reached—flag, scrutiny, taxpayer response, audit, investigation or finding—and avoid describing an earlier-stage signal as proof of fraud.
