GST Authorities Flag Fraud Attempts by Impersonators Posing as GST Officials

OFFICIAL TRADE NOTICE | CGST BENGALURU ZONE | 10 MARCH 2026

Trade Notice No. 02/2026 — Dated: 10 March 2026

Issued by: The Principal Chief Commissioner of Central Tax, Bengaluru Zone

Office: CR Building, Queen’s Road, Shivaji Nagar, Bengaluru – 560001

SUMMARY: Trade Notice No. 02/2026, issued on 10 March 2026 by the Principal Chief Commissioner of Central Tax, Bengaluru Zone, formally alerts all GST-registered taxpayers and trade within the Bengaluru Zone about a dangerous and escalating pattern of fraud in which persons misrepresent themselves as Central GST officials. The Notice warns against fake summons bearing forged Document Identification Numbers (DINs), impersonation of CGST officers, and other deceptive conduct designed to extort money from unsuspecting taxpayers. It reiterates taxpayers’ rights and provides clear guidance on verifying authentic government communications.

1. Background and Authority Behind the Notice

Trade Notices issued by the Principal Chief Commissioner of Central Tax carry significant administrative authority. The Bengaluru Zone is the largest CGST Zone in Karnataka, overseeing eight Executive Commissionerates (Bengaluru East, West, North, North-West, South, Belagavi, Mysuru, and Mangaluru), four Audit Commissionerates, and four Appeals Commissionerates. The Zone is headquartered at CR Building, Queen’s Road, Bengaluru, and administers GST, Central Excise, and erstwhile Service Tax laws across the State of Karnataka.

Trade Notice No. 02/2026, dated 10 March 2026, is the second trade notice issued by the office in 2026, following Trade Notice No. 01/2026 of 19 February 2026. Its issuance at the zonal level — rather than just a national advisory — signals that fraudulent impersonation of GST officers has been specifically reported and observed within Karnataka, warranting a direct, targeted communication to businesses and taxpayers registered in the Bengaluru Zone.

The Notice builds directly upon the national-level warning issued by CBIC/DGGI on 24 January 2025 (PIB Release ID: 2095881) and Circular No. 122/41/2019-GST dated 5 November 2019, which mandated the use of Document Identification Numbers (DINs) on all official CBIC communications. By echoing and amplifying this guidance at the zonal level, the Principal Chief Commissioner underscores that the fraud threat is active and real within Karnataka’s taxpayer community.

2. The Fraud: What the Trade Notice Describes

The Trade Notice specifically addresses the following patterns of fraudulent conduct that have come to the attention of Central Tax authorities in the Bengaluru Zone:

(A) Fake Summons and Notices with Fabricated DINs

Fraudsters have been generating counterfeit summons, notices, and letters that closely mimic official CBIC/DGGI communications. These fake documents misuse the official CBIC logo and carry what appear to be valid 20-digit Document Identification Numbers (DINs). However, as the Notice makes clear, these DINs are entirely fabricated and are not generated by any CGST officer through the official DIN system mandated by Circular No. 122/41/2019-GST.

The purpose of these fake documents is straightforward: to panic taxpayers into believing they are under investigation for GST violations, and to compel them to pay money — typically to private accounts, UPI IDs, or other unofficial channels — in order to “settle” fabricated demands.

(B) Direct Impersonation of Central GST Officers

Beyond paper-based forgery, the Notice warns of instances where individuals physically present themselves at business premises or contact taxpayers by phone, WhatsApp, or email, claiming to be officers of CGST, DGGI, or State GST. These impostors claim to have identified serious irregularities, threaten dire consequences including arrest and attachment of property, and demand immediate payment or personal meetings outside of official premises.

The Trade Notice makes clear that genuine CGST officers conducting inspections, searches, or investigations are required to follow prescribed procedures under the CGST Act, 2017 and always carry verifiable government identity credentials. Taxpayers encountering such persons should request credentials and independently verify them.

(C) Digital and Phone-Based Fraud

The Notice also flags digital impersonation — including emails from addresses that mimic official government domains, WhatsApp messages purportedly from senior tax officers, and automated phone calls using official-sounding IVR systems. These communications typically contain urgent demands for tax payments or ask taxpayers to click on malicious links to “regularise their compliance status.”

3. The DIN System: Your Primary Shield Against Fraud

At the heart of Trade Notice No. 02/2026 is a reaffirmation of the Document Identification Number (DIN) system, which serves as the definitive tool for authenticating official CBIC communications. The DIN framework was established by Circular No. 122/41/2019-GST and requires every official communication issued by a CBIC officer — whether a notice, summons, letter, or order — to carry a system-generated, unique 20-digit DIN.

Feature	Detail
What it is	A unique 20-digit alphanumeric code generated by the CBIC’s official IT system
Who it applies to	All officers of CBIC (CGST + Customs) — for all written communications to taxpayers
Governing circular	Circular No. 122/41/2019-GST dated 5 November 2019
Purpose	Ensures authenticity, accountability, and traceability of every official GST communication
Verification portal	https://esanchar.cbic.gov.in/DIN/DINSearch
What a match confirms	Issuing officer’s name, designation, office, and exact date of issue
What no match means	The document is NOT a genuine CBIC communication — treat as fraudulent
State GST notices	DIN rules for State GST officers are separate; verify with respective State GST authority

4. How to Verify a GST Communication: Step-by-Step

The Trade Notice directs taxpayers to use the following official process before responding to any GST communication:

Locate the DIN: Find the 20-digit Document Identification Number printed on the communication you received. A genuine CBIC notice will always have this prominently displayed.
Visit the CBIC e-Sanchar Portal: Go to https://esanchar.cbic.gov.in/DIN/DINSearch (do NOT use links from within the suspicious document itself).
Enter the DIN and complete the CAPTCHA verification on the portal.
Verify the result: A valid DIN will display the issuing officer’s name, designation, date, and issuing office. Any mismatch or blank result means the document is not authentic.
Cross-check the GSTIN: Verify the GSTIN of the alleged issuing formation at www.gst.gov.in under ‘Search Taxpayer.’
Contact only official channels: If you need to reach CGST Bengaluru Zone, use contact details from www.gstkarnataka.gov.in or www.cbic.gov.in — never from the suspected document.

CRITICAL REMINDER: A communication that cannot be verified via the DIN portal has no legal standing. You are under no obligation to respond to or comply with an unverified communication. Do not pay any amount until the DIN is confirmed as genuine.

5. Warning Signs: Identifying Fraud in Real Time

The Trade Notice draws taxpayers’ attention to the following red flags that indicate a communication or official approach is likely fraudulent:

Communication arrives via personal email, WhatsApp, SMS, or a domain that does not end in ‘.gov.in’
Payment demanded to a private bank account, UPI ID, mobile wallet, or cryptocurrency address
Extreme urgency: immediate arrest, property seizure, business suspension, or “last notice” language
Caller or visitor refuses to provide a verifiable government service identity card
DIN on the document returns no match or an error on the CBIC e-Sanchar portal
The communication cannot be traced or located on the official GST portal (www.gst.gov.in)
Request for a private meeting outside an official government office to “settle the matter”
Spelling errors, grammatical mistakes, or formatting inconsistencies in the document
Threat of consequences unless payment is made before the end of the business day
Communication claims to be from an officer but provides no official CBIC officer designation number

6. Taxpayer Action Plan: What To Do and What Not To Do

✅ DO	❌ DO NOT
Verify the DIN immediately on esanchar.cbic.gov.in	Do not pay any amount before verification
Save and preserve the suspicious communication as evidence	Do not click links or download attachments
Contact CGST Bengaluru Zone directly via official website	Do not use contact details from the suspect notice
Consult a registered CA, CMA, or GST Advocate	Do not share bank details, OTPs, or PAN/Aadhaar
File a report at www.cybercrime.gov.in	Do not agree to private meetings outside official offices
Report to local police if physically threatened	Do not panic or act under artificial urgency

9. Broader Context: Karnataka GST Fraud on the Rise

Trade Notice No. 02/2026 does not emerge in isolation. Karnataka has been at the centre of several significant GST enforcement actions in recent months. The Enforcement Wing of Karnataka’s Commercial Taxes Department uncovered a ₹1,464 crore fake billing scheme involving bogus firms in Karnataka and Tamil Nadu that fraudulently claimed Input Tax Credit (ITC) on paper transactions for construction materials — cement, iron, steel — with no actual supply of goods. Four accused were remanded to judicial custody by the Special Court for Economic Offences, Bengaluru.

Separately, DGGI Bengaluru dismantled a ₹593 crore fake ITC network, arresting the alleged kingpin under Section 69 of the CGST Act. The network operated through a web of shell companies generating fraudulent invoices to enable wrongful ITC transfers worth over ₹235 crore.

Nationally, Ministry of Finance data presented to Parliament showed that GST enforcement agencies detected evasion worth approximately ₹7.08 lakh crore across 91,370 cases between FY2020–21 and FY2024–25, with FY24–25 alone recording ₹2.23 lakh crore in detected evasion — the highest ever. It is against this backdrop of rampant fraud that Trade Notice No. 02/2026 assumes its full significance.

10. Conclusion

Trade Notice No. 02/2026 issued by the Principal Chief Commissioner of Central Tax, Bengaluru Zone, on 10 March 2026, is a timely and authoritative warning that deserves the full attention of every business and individual taxpayer registered within Karnataka. The Bengaluru Zone, overseeing the entire state’s Central Tax administration, has taken the unusual step of issuing a formal Trade Notice — not merely a press advisory — to communicate the urgency of the threat.

The message is unambiguous: real GST officers do not demand money over the phone, do not ask for payments to private accounts, and do not threaten immediate arrest without following due process under the CGST Act. Every official communication they send carries a verifiable DIN. Any departure from these norms is the hallmark of a fraud.

CORE TAKEAWAY: Before responding to any GST notice, summons, or official approach — verify the DIN at esanchar.cbic.gov.in. If it does not verify, do not pay, do not comply, and report immediately to CGST Bengaluru Zone or the National Cyber Crime portal.
