TL;DR
A GST engagement letter defines scope, fees, and liability for each GST client — ICAI-recommended best practice. Manual templating takes 10–15 minutes per client; AI-powered document automation reduces this to under 60 seconds, saving CAs 3–4 hours weekly on client documentation alone.
What Is a GST Engagement Letter?
A GST engagement letter is a formal document between a Chartered Accountant (or tax consultant) and a client, defining the scope of GST-related services — such as GSTR-1 filing, GSTR-3B reconciliation, annual return preparation, and advisory on Input Tax Credit. It protects both parties by clearly stating fees, responsibilities, timelines, and liability limits.
Under ICAI guidelines, CAs are encouraged to issue engagement letters for every client engagement to avoid scope creep, fee disputes, and professional liability exposure.
What a GST Engagement Letter Should Include
- Client legal name, GSTIN, and address
- CA firm name, registration number, and address
- Scope of services (specific GST returns, advisory, audit representation)
- Fee structure and payment terms (monthly retainer or per-filing)
- Engagement period and renewal terms
- Client obligations (providing records by a specified date)
- Limitation of liability clause
- Confidentiality and data protection clause
- Dispute resolution and governing jurisdiction
- Signature block with date

Frequently Asked Questions
Is a GST engagement letter mandatory for CAs?
It is not legally mandatory under GST law, but ICAI strongly recommends engagement letters for all professional engagements to protect both the CA and the client. Many professional indemnity insurers also require documented engagement letters.
Can I use the same template for all GST clients?
Yes — the structure is the same. Only the client-specific fields (name, GSTIN, fee, scope, dates) change. This is exactly why automating with Glomiq saves hours each month: one template, infinite client-specific outputs.
What GST returns should be listed in the engagement letter?
List only the returns your firm will actually file. Common inclusions: GSTR-1, GSTR-3B, GSTR-9, GSTR-9C. If ITC reconciliation or representation services are in scope, specify them separately to avoid scope creep.
Does Glomiq work with ICAI-standard document formats?
Glomiq works with any Word or PDF document you upload — including your firm's letterhead and existing ICAI-compliant templates. The AI adapts to your format, not the other way around.
