Engagement Letters in GST Era: Shield Against 122(3A) Risk

Section 122(3A) of the CGST Act exposes “any person,” including GST professionals, to penalties for alleged facilitation of offences such as fake invoicing and bogus input tax credit. In this context, a clear written engagement letter functions as a risk-management tool alongside client KYC procedures to demonstrate good faith and due diligence. A GST-specific engagement letter defines the limited scope of services, records that responsibility for accuracy of data and compliance rests with the registered person, and clarifies that the professional does not undertake to detect all fraud. It also documents warnings against wrongful ITC or fake transactions and provides for indemnity if client misconduct leads to proceedings, including under Section 122(3A). Key clauses should cover scope, responsibilities, fraud disclaimers, indemnity, fees, confidentiality, termination, and jurisdiction. When consistently used with proper KYC and documentation, such engagement letters help reduce exposure to allegations of “knowing facilitation” and protect professionals from avoidable litigation and penalties.

Engagement Letters in GST Era: Shield Against 122(3A) Risk

Section 122(3A) exposes “any person” – including external GST professionals – to penalty where they are alleged to have facilitated specified GST offences such as fake invoicing and bogus ITC. In this backdrop, a clear, written engagement letter is no longer a formality but a risk‑management tool that complements your client KYC framework and helps demonstrate good faith and due diligence.

Your earlier client KYC checklist already focuses on verifying identity, business reality and compliance behaviour, and on documenting that factual data and commercial decisions remain the client’s responsibility. The natural next step is to ensure that every GST assignment is backed by a concise engagement letter and an indemnity from the client, especially where later economic offences cannot be ruled out.

Why GST Engagement Letters Matter

A GST‑specific engagement letter serves at least four purposes in the current environment:

It defines the limited scope of your work (e.g., return filing, advisory, representation) and avoids an implied duty to police every transaction of the client.

It records that primary responsibility for correctness and completeness of data, invoices, e‑way bills and underlying commercial arrangements lies with the registered person, not with the consultant.

It evidences that you have cautioned the client against wrongful ITC, fake invoices or benami registrations, which is relevant when rebutting any allegation of “knowing facilitation” under section 122(3A).

It provides a contractual basis for indemnity if the client’s economic offences drag you into avoidable litigation costs, reputational damage or penalties.

Courts have also emphasised that GST liability primarily attaches to the registered person and cannot be mechanically shifted to the professional merely because he handled filings. A well‑drafted engagement letter, coupled with your KYC records and red‑flag notes, helps you invoke this principle when needed.

Key Clauses to Cover (With Minimal Length)

Even a “short” format engagement letter for GST work should typically include:

Parties and period: Names, GSTIN, addresses, and financial year/period covered by the engagement.

Scope of services: Brief bullet list (e.g., GST registration support, periodic returns, reconciliation, replying to notices, representation up to a specified level).

Client responsibilities: Clear statement that client will provide true, complete data and original records; ownership of tax positions and commercial decisions rests with management.

Professional responsibilities: Application of due care in law and procedure, no assurance on detection of all frauds, reliance on information provided by client unless something is patently inconsistent.

122(3A) and fraud disclaimer: Clarify that you neither participate in nor design any scheme for tax evasion, and that any use of fake invoices, benami entities or accommodation entries is strictly prohibited and outside engagement.

Indemnity for economic offences: Client agrees to indemnify and hold you harmless from consequences arising out of its wilful misstatements, concealment, bogus ITC, fake invoicing or other economic offences, including any proceedings under section 122(3A).

Fees and billing: Basis (fixed, hourly, per‑return) and due dates; mention that additional work (e.g., investigation, search/seizure support) is extra.

Confidentiality and data use: Reasonable confidentiality, subject to statutory disclosures and production before authorities.

Termination: Either‑side termination with notice; automatic termination on non‑cooperation, suspected fraud or non‑payment.

Governing law and jurisdiction: Reference to applicable law (e.g., CGST Act and relevant State GST Act) and agreed jurisdiction.

These elements can be captured in 2–3 pages, yet they provide a robust documentary shield when combined with a structured KYC file.

Subject: Engagement letter for GST services

Dear Sir / Madam,

Appointment and period

You have requested us to act as your GST advisor/consultant for the period from __________ to __________ in respect of the above GSTIN(s). We agree to accept this engagement on the terms set out in this letter.

Scope of services

Subject to timely receipt of information and documents from you, our services will broadly cover:

a) Assistance in GST registration/amendment, if required.

b) Preparation and filing of periodic GST returns and statements (including GSTR‑1, GSTR‑3B and annual return, as applicable).

c) Assistance in basic reconciliations of outward and inward supplies with books and portal data.

d) Guidance on routine GST queries and compliances within the normal course of our engagement.

e) Assistance in preparing replies to notices/intimations and appearance before GST authorities up to the _______ level, if specifically authorised.

Any work beyond the above (including representation in audit, investigation, search, summons or appeal proceedings) will be a separate assignment on mutually agreed terms.

Your responsibilities as registered person

You acknowledge and agree that:

a) You are solely responsible for the correctness, completeness and legal compliance of all information, records and documents (including invoices, e‑way bills, purchase records, debit/credit notes, stock and financial statements) provided to us.

b) All commercial decisions, determination of nature of supply, place of supply, valuation, eligibility of input tax credit and classification of goods/services are your responsibility, though we may provide professional views based on facts disclosed to us.

c) You will provide us, within agreed timelines, all data and documents required for preparation and filing of returns and for responding to departmental notices.

d) You will promptly inform us of any show cause notices, summons, searches, inspections or investigations initiated by any GST authority and will share all relevant documents.

Our responsibilities and limitations

We will perform the engagement with reasonable professional skill and care, in accordance with applicable GST law, rules, notifications and generally accepted professional standards. Our work will be based on information and explanations given by you and will not constitute an audit or investigation, nor will it necessarily detect fraud, irregularity or error, if any.

We do not undertake to verify the genuineness of every transaction or document beyond basic plausibility checks and statutory requirements. We will not be responsible for any consequences arising from misstatements, concealment, back‑dated entries, bogus transactions, accommodation entries, fake invoices, benami entities or other irregularities on your part which are not apparent from the information made available to us.

Prohibition on facilitation of GST fraud and 122(3A) disclaimers

Our engagement does not extend to, and we will not advise on, structure or implementation of any arrangement involving:

Use of fake or non‑existent suppliers or customers.

Passing or availing of ineligible/bogus input tax credit.

Circular trading or paper transactions without actual movement of goods or provision of services.

Benami registrations or use of name‑lenders.

You expressly confirm that you will not request us to prepare, file or support any document, return or reply which is false, misleading or intended to facilitate evasion of tax. If at any stage we, in our professional judgment, suspect that our continued association may amount to, or be alleged as, facilitation of an offence under section 122(3A) of the CGST Act or any corresponding provision, we reserve the right to immediately withdraw from the engagement and to place on record our professional position before the appropriate authority.

Indemnity for economic offences and misstatements

You agree to indemnify and keep us, our partners and staff fully indemnified and harmless from and against all claims, demands, penalties, interest, costs, expenses and proceedings (including those initiated under section 122, section 122(3A) or any other penal provision of GST law, or under economic offences laws) to the extent such action arises out of:

a) Any false, incomplete or misleading information, documents or explanations provided by you or on your behalf.

b) Any suppression or non‑disclosure of material facts, including actual nature of transactions, related party relationships, or sources of funds.

c) Any use of fake invoices, benami entities, circular trading or other fraudulent arrangements entered into by you or your related parties, whether or not disclosed to us.

This indemnity will survive termination of this engagement.

Fees and billing

Our professional fees for the above services will be as per Annexure‑A or as otherwise agreed in writing from time to time. Out‑of‑pocket expenses, government fees and third‑party charges (if any) will be charged separately. Fees are payable within ______ days of invoice; delay may result in suspension of services.

Confidentiality and use of information

We will maintain confidentiality of your information to the extent required under law and professional ethics, except where disclosure is required by law, by professional standards or by any judicial/administrative authority. We may use your data in anonymised form for internal knowledge, training or publication purposes, without disclosing your identity.

Duration and termination

This engagement will remain in force for the period mentioned in Clause 1 and will automatically continue for subsequent periods unless terminated by either party by ______ days’ written notice. We may terminate the engagement with immediate effect in case of non‑payment of fees, persistent non‑cooperation, or where we believe that continuing the engagement may be unlawful, unethical or prejudicial to our professional standing.

Governing law and jurisdiction

This engagement letter shall be governed by the laws in force in India, including the CGST Act and applicable State GST Act. Any dispute arising out of this engagement shall be subject to the exclusive jurisdiction of the courts/appropriate forums at ___________.

If the above terms are acceptable, please sign and return a copy of this letter as token of your acceptance.

Yours faithfully,

Practical Adoption Tips for Practitioners

To embed this format into everyday practice without increasing compliance burden:

Attach the engagement letter and indemnity clause at client onboarding stage along with your KYC checklist and maintain them in a single file (physical or electronic).

For small taxpayers, you can combine scope, responsibilities and indemnity into a 2‑page version, but avoid deleting the fraud‑prohibition and 122(3A) references.

Review and renew engagement letters at major transition points – change of management, significant turnover jump, new business verticals or adverse notices/audits.

Train staff to refuse instructions that conflict with the prohibitions recorded in the letter (e.g., knowingly uploading fake invoices or back‑dated entries).

Used consistently along with robust client KYC, this concise engagement format can significantly reduce the risk that honest GST professionals are unfairly treated as “facilitators” under section 122(3A).
