GST Data Analytics Red Flags That Trigger Notices: Finance-Team Checklist
GST notices increasingly start from data mismatches: outward supplies, e-way bills, e-invoices, ITC, GSTR-2B, GSTR-3B and books not telling the same story. The best defence is a monthly analytics pack before the department asks for one.
Use the GST Refund Route and RFD-01 Checklist to apply these points to your figures or facts.
Official scrutiny framework
Section 61 provides for scrutiny of returns and Rule 99 covers scrutiny-related procedure. Where explanation is not satisfactory or further action is required, issues may move into demand or other statutory workflows. This is why mismatch resolution should be documented early.
For the connected rule, example or next step, see GST Data Analytics Red Flags: What Triggers Notices.
Top red flags to monitor
| Red flag | Finance-team control |
|---|---|
| GSTR-1 turnover higher/lower than GSTR-3B | Prepare period-wise reconciliation and reasons. |
| GSTR-2B ITC vs books gap | Vendor-wise pending credit tracker. |
| High e-way bill value vs return turnover | Map dispatches, stock transfers, job work and cancelled invoices. |
| Refund claims with weak zero-rated evidence | Keep LUT, invoices, FIRC/BRC and refund workings. |
| Credit ledger restriction or unusual ITC spike | Keep vendor and business-use evidence ready. |
For the connected rule, example or next step, see GSTR-9C Reconciliation Statement: Auditor and Finance Team Checklist.
