Indian GST authorities use data analytics and AI-related capabilities to help identify returns or taxpayers for scrutiny and verification. Selection is a way to direct an officer’s attention; it is not, by itself, a finding of wrongdoing or a final tax demand. If you receive a scrutiny notice, the discrepancy and deadline stated in that notice should guide your response.
What “AI-based GST scrutiny” means
In public descriptions of GST administration, analytics and AI are part of a wider system for examining data and identifying risks. They can help officials select returns or taxpayers for further review, match information, and surface discrepancies for an officer to examine. The publicly described process is therefore better understood as analytics-assisted scrutiny than as an automated decision that independently establishes a taxpayer’s liability.

The Central Board of Indirect Taxes and Customs (CBIC) said on 11 May 2023 that it had rolled out an Automated Return Scrutiny Module in the ACES-GST backend for Central Tax Officers. The module supports scrutiny of Centre-administered taxpayers selected using data analytics and system-identified risks. Officers can view associated discrepancies and use a GSTN Common Portal workflow to communicate them. CBIC said the rollout began with returns for financial year 2019–20; that describes the launch scope, not a rule that scrutiny is now confined to that year.
In a separate 2023 statement, the Ministry of Finance described CBIC’s ADVAIT project as an indirect-tax analytics initiative using big-data and AI capabilities. The described capabilities include reports and dashboards, analytical models, data matching, network analysis, pattern recognition, and predictive analytics. These are administrative tools and capabilities, not a published checklist of signals that a taxpayer can use to predict selection.

How analytics can lead to officer review
Different official descriptions illuminate different parts of the process. NIC describes GST Prime as an officer-facing analytical tool that connects the GST Common Portal with e-way-bill systems. Its listed functions include taxpayer profiles, risk-based analysis to identify cases for scrutiny or audit, matching statements and external data, and examining supply chains and possible circular trading. NIC says GST Prime generates more than 80 analytical and statistical reports. That figure counts reports; it does not say how many taxpayers are selected, how frequently notices are issued, or how often a discrepancy is confirmed.
Taken together, these descriptions indicate that data from GST administration systems and other information can be analyzed to help identify cases for attention. The officer-facing tools may help put information into context, but the public material does not disclose the complete scoring formula, weights, thresholds, or a universal trigger list. It also does not publish false-positive rates. A taxpayer therefore cannot infer from a particular transaction or filing choice alone that a system will—or will not—select their return.
Risk identification has also been used in other contexts. For example, CBIC Instruction 02/2024-GST described GSTN and DGARM identifying suspicious or high-risk GSTINs for a special fake-registration drive scheduled from 16 August to 15 October 2024. That was a time-bound historical drive, not evidence of a current campaign or a universal trigger for ordinary return scrutiny.

Selection is followed by an officer-led process. Under CBIC’s rules page, if a return is selected for scrutiny and the proper officer finds a discrepancy, the officer issues FORM GST ASMT-10. The notice states the discrepancy, seeks an explanation, and quantifies the related tax, interest, or other amount. The response period specified in the notice cannot exceed 15 days from service under the procedure described there. Check the actual notice and current applicable law for the deadline that applies to your case.
The notice is an opportunity to address an identified issue. It is not, by itself, proof of fraud or a final demand. CBIC’s 2023 description of the module says the workflow may be followed by acceptance of a reply, a show-cause notice, or initiation of an audit or investigation. Those are possible subsequent routes, not automatic consequences of receiving ASMT-10.
Your response routes
- Explain the discrepancy: Submit an explanation in FORM GST ASMT-11, with relevant supporting information. Organize the response around the specific point raised rather than sending unrelated records.
- Accept and pay: If you accept the discrepancy, the rules describe a route to accept it and pay the amount. Follow the instructions applicable to the notice and verify the amount and payment requirements before acting.
- Officer accepts your explanation: If the officer accepts the explanation or information, the officer informs you in FORM GST ASMT-12.
The exact notice, its stated response date, and applicable current law govern what you need to do. If the amount is material, the issue is complex, or the notice raises a matter you cannot reconcile, consider obtaining advice from a qualified GST practitioner or tax professional promptly enough to meet the response deadline.
What GST records to keep ready
There is no single exhaustive document checklist for every scrutiny issue. Start with the discrepancy and any specific document request in ASMT-10; then assemble the records that explain the relevant return figures. A practical file can include the following, as applicable:

- Returns and workings: Filed GST returns for the period at issue and the calculations or period-specific workings behind the reported figures.
- Books and transaction records: Books of account and source records supporting turnover and the treatment of exemptions or deductions.
- Rate support: Records showing how you determined the tax rate applied to the goods or services involved in the discrepancy.
- Invoices and ITC support: Relevant sales and purchase invoices and other transaction evidence, including records supporting input tax credit (ITC) claimed and used where the issue concerns credit.
- Refund support: Refund claim workings and supporting documents if the notice concerns a refund.
- Reconciliation and correspondence: A clear reconciliation or explanation that links the source records to the return figures, plus copies of the notice and the response submitted.
This preparation list reflects matters CBIC says may be examined in an audit, including books and source documents, returns and statements, turnover, exemptions and deductions, tax rates, ITC, refunds, and related issues. It is a way to organize potentially relevant evidence, not a substitute for the particular documents requested in your notice.
Make the file easy to review
- Identify the exact period and issue. Note the tax period, discrepancy, amount, and response date shown in the notice. Do not assume that a mismatch in one period explains another period.
- Trace each figure to its source. For every figure discussed in your explanation, identify the return entry and the underlying ledger, invoice, calculation, or other record that supports it.
- Reconcile differences directly. If the issue involves figures that do not appear to match, prepare a concise reconciliation showing how the relevant records relate to the reported amount. Explain the basis for any difference rather than relying on a general statement that the return is correct.
- Send only relevant, legible support. Use the notice’s directions for submitting the explanation and documents. Keep a copy of what you submit and evidence of submission.
These steps are practical ways to present records, not a claim that the rules prescribe a particular file format or require every taxpayer to submit every category listed above.

Official descriptions mention scrutiny, audit, and verification in related but distinct contexts. A risk tool may identify cases for an officer to examine, but the procedural route depends on what the authority does next and which notice or request is issued. Do not treat the words “selected,” “scrutiny,” “audit,” and “investigation” as if they describe one identical process.
For a scrutiny discrepancy, the CBIC rules page describes ASMT-10 and an explanation route through ASMT-11, with ASMT-12 used to inform the taxpayer when an explanation or information is accepted. The Automated Return Scrutiny Module’s 2023 description says a scrutiny workflow may be followed by acceptance, a show-cause notice, or an audit or investigation. The notice you actually receive—not the possibility of a later route—determines what you must address at that stage.
What taxpayers can and cannot conclude about risk
The government’s public materials support the conclusion that analytics, risk parameters, and AI-related capabilities are used in GST administration. They describe tools for risk-based identification, matching information, and helping officers examine cases. They do not disclose a complete taxpayer-facing risk score, scoring weights, selection thresholds, false-positive rates, or an exhaustive list of behaviors that will trigger scrutiny.
No published statistic is established here for the number or share of taxpayers selected, notices issued, or scrutiny outcomes. The published GST Prime figure—more than 80 reports, according to NIC’s page updated in 2026—is a description of system reporting capabilities, not a measure of enforcement activity. Avoid treating broad lists of possible analytics functions as confirmed triggers for your own return.
Quick Recap
Practical takeaways
- Analytics can help authorities identify returns or taxpayers for officer scrutiny or verification; selection is not a final finding.
- If ASMT-10 is served, work from the discrepancy and response deadline stated in that notice, and organize evidence that addresses the issue.
- The procedure described by CBIC provides for an explanation through ASMT-11, acceptance and payment where appropriate, and notification in ASMT-12 if the officer accepts the explanation or information.
- Public sources describe the tools and workflows, but not a complete formula for predicting which taxpayer will be selected.
