GST Evasion: Fraud Patterns & 8-Stage Investigation Workflow

 The eight-stage practical workflow for detecting and investigating GST evasion provides a systematic framework for tax officers:

1. Stage 1 — Risk Identification: The process begins by analyzing available departmental data—including GSTR-1, GSTR-3B, GSTR-2B, e-invoices, e-way bills, registration profiles, and other authorized data—to identify unusual patterns rather than relying on a single isolated mismatch.
2. Stage 2 — Preliminary Data Analysis: A taxpayer-wise reconciliation is prepared across turnover streams (GSTR-1, GSTR-3B, books of account, e-invoices, e-way bills) and Input Tax Credit (ITC) components (GSTR-2B, purchase register, GSTR-3B, ITC ledger, legal eligibility).
3. Stage 3 — Obtain Documentary Evidence: Depending on the specific issue under review, relevant supporting records are gathered, such as sales/purchase registers, general ledgers, trial balances, financial statements, tax invoices, credit/debit notes, e-way bills, stock registers, bank statements, transport documents, and commercial contracts.
4. Stage 4 — Communicate the Discrepancy: For scrutiny proceedings under Section 61 (read with Rule 99), the officer issues FORM GST ASMT-10 specifying the discrepancy and requesting an explanation. The taxpayer submits a reply in FORM GST ASMT-11; if acceptable, FORM GST ASMT-12 is issued, recognizing that accounting mismatches do not automatically constitute evasion.
5. Stage 5 — Move From Scrutiny to Investigation Where Required: If the evidence reveals serious issues—such as fake invoices, non-existent suppliers, suppressed turnover, fraudulent ITC, circular trading, or organized evasion—the matter escalates from routine scrutiny to full investigation and enforcement proceedings.
6. Stage 6 — Establish the Tax Impact: The officer quantifies the government dues by calculating short-paid tax, applicable interest, and penalties under the relevant statutory provisions (such as applying Section 74A where applicable).
7. Stage 7 — Search, Seizure, or Inspection Where Legally Justified: If statutory conditions under Section 67 are met (rather than mere data mismatches), search or inspection operations are executed adhering strictly to procedural standards, including proper authorization, Panchanama documentation, statement recording, evidence preservation, and electronic record handling.
8. Stage 8 — Adjudication and Further Enforcement: Where a tax demand is legally sustainable, formal adjudication follows a structured path: Show Cause Notice (SCN) → Reply → Personal Hearing → Adjudication Order → Recovery/Consequential Action. In severe cases, further statutory enforcement or prosecution under Section 132 may be evaluated.
