Investigation, DGGI & Enforcement Matters

The Directorate General of GST Intelligence (DGGI) is the Central Board of Indirect Taxes and Customs' dedicated central intelligence and enforcement agency. It investigates large-scale, often multi-state GST evasion — fake invoicing, fraudulent ITC networks, clandestine removal of goods — that a single state's or commissionerate's jurisdictional officer typically cannot pursue on their own because their proper-officer jurisdiction is generally confined to their own state or zone. Your regular jurisdictional CGST/SGST officer handles routine registration, return processing, and standard departmental audits under Section 65.

Section 70 of the CGST Act empowers a proper officer to summon any person whose attendance is considered necessary, either to give evidence or to produce documents. A summons can require personal attendance, or it may permit document production through an authorised representative depending on how it is worded — read the summons carefully for what it actually demands. A proceeding under summons is deemed a judicial proceeding, meaning giving false evidence carries the same criminal exposure as doing so before a court.

There is no absolute statutory right under the CGST Act for a representative to be physically present in the room during the recording of a statement under Section 70, and practice varies by officer and circumstance — some permit the representative to be present at a visible but not necessarily audible distance, some do not. What PNPC does regardless of physical presence in the room is comprehensive preparation beforehand and a thorough debrief and documentation review immediately afterward.

Section 67 permits a proper officer, based on a written 'reason to believe' that goods liable to confiscation or documents/things relevant to proceedings are secreted at a place, to authorise inspection, and where warranted, search and seizure. The officer can search the premises, seize books, documents, and things, and access electronic records and digital devices where relevant to the investigation. A panchnama (search record) is prepared listing everything seized, and this document is central to every subsequent stage of the matter.

Section 69 of the CGST Act permits arrest where the Commissioner has reason to believe a person has committed an offence specified under Section 132(1)(a) to (d) — broadly, offences involving fake invoicing without underlying supply, fraudulent availment of ITC using such invoices, and similar categories — and the amount involved crosses the threshold that makes the offence cognizable and non-bailable, currently ₹5 crore for the more serious offence categories, with a lower threshold applying to offences that remain cognizable but bailable. Arrest requires the Commissioner's written authorisation, and the arrested person must be produced before a magistrate within 24 hours.

Section 83 permits the Commissioner to provisionally attach property, including bank accounts, for up to one year, where this is considered necessary to protect government revenue during the pendency of specified proceedings. The attachment is meant to be proportionate and time-bound, not an automatic or indefinite freeze. A taxpayer can file an objection and seek release or modification, including partial release for genuine operational needs such as payroll and statutory dues.

Rule 86A of the CGST Rules allows an officer, on reason to believe that credit in the electronic credit ledger has been fraudulently availed or is ineligible, to block the ledger — preventing its use for payment of output tax or refund — for up to one year, without a prior show-cause notice. It is a preventive measure, distinct from a formal demand under Section 74A (or the earlier 73/74), which requires notice, reply, and adjudication before any liability is confirmed.

Historically, Section 73 governed demands where tax was short-paid or ITC wrongly availed without fraud, wilful misstatement, or suppression — carrying a lower penalty and standard limitation. Section 74 governed the same categories where fraud, wilful misstatement, or suppression was involved — carrying a higher penalty and an extended limitation period. Effective for tax periods from FY 2024-25 onwards, both provisions have been consolidated into a single Section 74A, which retains the underlying non-fraud versus fraud/suppression distinction for penalty purposes but applies a common limitation period and procedure regardless of category. Demands relating to periods before FY 2024-25 continue to be governed by the pre-amendment Sections 73 and 74 as they stood at the time.

Sections 73(5) and 74(5) of the CGST Act (and the corresponding provision under Section 74A for later periods) allow a taxpayer to pay the tax, interest, and a reduced penalty voluntarily, before a formal show-cause notice is issued, once the facts and quantum are reasonably clear. Where genuinely warranted by the facts, this route accesses a materially lower penalty than paying after a notice or after adjudication. It is not appropriate in every case — where the facts are disputed or the department's position is legally weak, contesting the matter may be the better route.

Personal liability for a director, partner, or authorised signatory depends on their actual role and involvement in the transactions under investigation, not merely their formal designation. Sections 137 and related provisions of the CGST Act address liability of officers of a company/firm in specified circumstances, generally where the offence is shown to have been committed with the person's consent, connivance, or attributable to their neglect. A person with no substantive decision-making role in the disputed transactions has a materially different exposure profile from an active decision-maker.

Fake invoicing refers to the issuance of a tax invoice for goods or services without any actual underlying supply, typically to enable the recipient to fraudulently claim Input Tax Credit that has no genuine corresponding transaction behind it. Because ITC is a pass-through credit mechanism, fake invoicing directly drains government revenue without any real economic activity taking place, and it is frequently structured as a layered, circular-trading network across multiple entities to obscure the absence of genuine supply. This is treated as one of the most serious categories of GST offence under Section 132, carrying the higher arrest and prosecution thresholds.

Section 129 permits detention and seizure of goods and the conveyance transporting them where they are found, during movement, to be in contravention of GST law — most commonly an e-way bill defect, mismatch, or absence. Release is typically available on payment of the applicable tax and penalty, or on furnishing adequate security, pending resolution of the underlying dispute. Where the contravention is found to involve intent to evade tax, or is a repeat/aggravated violation, the matter can escalate to confiscation proceedings under Section 130.

Under the pre-amendment Section 73 (non-fraud cases for periods before FY 2024-25), the order must generally be passed within 3 years from the due date of the annual return for the relevant year. Under the pre-amendment Section 74 (fraud/suppression cases for the same earlier periods), this extends to 5 years. For tax periods from FY 2024-25 onward, the consolidated Section 74A applies a common limitation period regardless of the fraud/non-fraud classification, though the penalty slab still depends on that classification. The show-cause notice itself must typically be issued a specified number of months before the limitation deadline for the order.

Section 138 of the CGST Act permits compounding of most offences under Section 132, on payment of a compounding amount and subject to conditions prescribed by the government, allowing the person to avoid or terminate criminal prosecution. However, compounding is not available in certain circumstances — including where the person has already been convicted of an offence under GST law or a corresponding offence under an earlier indirect tax law by a court, and in certain other specified categories of repeat or aggravated offences. Eligibility is fact- and case-specific.

To file a first appeal before the Commissioner (Appeals) under Section 107, a taxpayer must pre-deposit 10% of the disputed tax amount (in addition to the admitted, undisputed tax and interest already required to be paid). For a further appeal before the GST Appellate Tribunal (GSTAT) under Section 112, an additional pre-deposit is required (broadly, a further percentage of the disputed tax over and above the first-appeal deposit), subject to a prescribed monetary cap. This pre-deposit requirement applies regardless of the eventual merits of the appeal.

The GST Appellate Tribunal is the second-level appellate forum for GST disputes, provided for under the CGST Act, with a Principal Bench and State Benches intended to hear appeals against orders of the Commissioner (Appeals). Its benches have been becoming operational progressively across jurisdictions rather than all at once, and the practical availability of a functioning bench in a given location should be checked at the time an appeal is contemplated, since procedural timelines and interim relief options depend on it.

GST enforcement is designed to avoid duplicate parallel proceedings on the same subject matter by different authorities, and CBIC/GST Council guidance generally directs that once one authority (central or state) has initiated action on a specific issue for a taxpayer, the other should not separately initiate proceedings on the same issue for the same period. In practice, coordination is not always perfect, and a taxpayer facing seemingly duplicate proceedings from both a state authority and DGGI should raise this at the earliest opportunity.

DGGI's targeting draws heavily on data analytics matching GSTR-1 (outward supplies), GSTR-3B (summary return and tax payment), GSTR-2B (auto-populated ITC statement), e-way bill data, and e-invoice data against each other, alongside intelligence inputs, whistleblower information, and patterns flagged from prior investigations (such as newly registered entities with unusually high turnover in a short period, or clusters of entities transacting heavily with each other with limited genuine business rationale).

A statement recorded under Section 70 is given on oath and carries significant evidentiary weight. Guessing or speculating to fill a gap in memory is a materially worse approach than accurately stating that you do not recall a specific detail and offering to check records and respond in writing subsequently. An inaccurate statement, even if unintentional, can be difficult to correct later and can be used against the deponent.

A GST investigation into suspected fake invoicing, undervaluation, or clandestine supply frequently has parallel income-tax implications — unaccounted sales, disallowed purchases, or transactions relevant to an income tax search or reassessment. Information gathered by DGGI is often shared with the Income Tax Department and, in cases with a suspected money-laundering angle, with the Enforcement Directorate. These are legally separate proceedings under separate statutes, but the underlying facts frequently overlap.

Effective September 2025, GST rates were rationalised from the earlier four-slab structure (5%/12%/18%/28%) to a simplified structure of broadly 5%/18%/40% for most goods and services, with the 40% slab applying to a narrow category of sin/luxury goods. This is a prospective rate change and does not, by itself, alter the tax treatment or applicable rate for supplies made in periods before the change took effect. A DGGI investigation into an earlier period is assessed against the rate structure that applied at the time of the disputed supply, not the current structure.

Yes. State GST departments have their own enforcement and intelligence wings operating under largely parallel provisions of the respective State GST Acts, mirroring the CGST Act's search, summons, arrest, and demand provisions. PNPC represents clients before both central DGGI and state enforcement authorities, since the underlying legal framework, evidentiary considerations, and defence strategy are substantially similar.

This varies enormously and cannot be predicted with false precision. A matter resolved through voluntary payment at the investigation stage, before a formal notice, can conclude within weeks to a few months. A matter that proceeds to a formal show-cause notice, adjudication, and appeal can extend over several years, particularly if it reaches the GST Appellate Tribunal or High Court. Quantum, complexity, the number of tax periods and entities involved, and whether prosecution is invoked all materially affect the timeline.

Any document described as an 'admission,' 'acknowledgement of liability,' or a statement summarising the officer's understanding of facts (as opposed to a factual document you are simply producing, such as an invoice or bank statement) should be reviewed before signing. Signing an acknowledgement of a summary prepared by the officer, without independently verifying that it accurately reflects what was actually said, can create a binding admission that is very difficult to walk back later.

Under Section 67, a search authorisation extends to access of electronic records and digital devices where relevant to the investigation, and officers can seek to access accounting software, email, and electronic communication where it is considered relevant. The specific scope of what may be accessed, imaged, or seized should be reviewed against the actual search authorisation issued, since overreach beyond the scope of the authorisation is a valid ground for objection.

A summons alone does not mean an adverse outcome is inevitable — many summonses are issued for routine information gathering, third-party verification (where your business is a supplier or customer of another entity actually under investigation), or preliminary fact-finding. The correct response is calm, organised, and properly represented cooperation — not panic, and equally not a defensive refusal to engage. The way the matter is handled from the first response materially affects whether it stays a limited inquiry or escalates.

The panchnama is the contemporaneous record prepared during a Section 67 search, documenting what was searched, what was found, and what was seized, typically witnessed by independent panch witnesses. It becomes a foundational document in every subsequent stage of the matter — the demand, the adjudication, and any prosecution will all reference back to what the panchnama records. Any inaccuracy or omission in it, if not raised at the time or very shortly after, is far harder to correct later.

A closure at the investigation stage (no show-cause notice issued, or a 'no further action' communication) generally means the Department is not proceeding further on the specific issue examined for the specific period reviewed. It does not necessarily preclude a fresh inquiry on a different issue or period if new information subsequently comes to light, though revisiting a matter that was genuinely and thoroughly examined and closed is uncommon absent new facts.

We regularly engage before any summons is issued — for businesses that suspect they may be drawn into a supplier's or customer's ongoing investigation, that have identified an internal ITC or invoicing anomaly they want assessed proactively, or that simply want a periodic GST compliance health check specifically calibrated to reduce enforcement risk (GSTIN verification discipline for key counterparties, ITC documentation hygiene, e-way bill and invoice reconciliation).

Fees for enforcement matters are scoped individually because the work required varies enormously — a straightforward summons response is a fundamentally different engagement from a multi-year, multi-entity investigation involving search, arrest-risk coordination, and appeal. PNPC provides a written scope and fee estimate before commencing substantive work on any enforcement matter, updated as the matter's complexity becomes clearer.

A DGGI matter is fundamentally a tax and accounting dispute at its core — reconciling GSTR filings, tracing payment trails, assessing ITC eligibility, and computing quantum — before it becomes, in some cases, a criminal law matter. PNPC's CA team leads the tax reconciliation, documentation, and adjudication representation, and coordinates directly with litigation counsel for arrest-risk, bail, and prosecution defence where those become necessary — giving the client one coordinated team rather than a CA and a lawyer working from separate, potentially inconsistent factual narratives.

Where a GST investigation touches transactions with a UAE-based related entity, invoicing structures involving a Dubai office, or fund flows that cross both jurisdictions, PNPC's Chennai, Bangalore, Hyderabad, and Dubai offices work as one coordinated team rather than requiring the client to brief two separate firms in two countries. This matters particularly where the investigation examines whether cross-border invoicing reflects genuine commercial substance.

The most common and costly mistake is treating the first summons casually — sending an employee unprepared to give a statement, handing over documents without a proper inventory or copy retained, or trying to resolve the matter directly with the officer without a documented paper trail of what was discussed and agreed. The second most common mistake is the opposite extreme: refusing to engage cooperatively at all, which tends to escalate scrutiny rather than reduce it.

No. GST liability, penalty, and prosecution are governed entirely by the statutory framework — there is no informal or off-the-record settlement mechanism with an individual officer. The only recognised routes to resolve or reduce exposure are voluntary payment under Section 73(5)/74(5)/74A, formal adjudication, appeal, and, for prosecution specifically, statutory compounding under Section 138. Any suggestion of an informal resolution outside these statutory mechanisms should be treated with serious caution.
