GST Audit, Assessment, DGGI Summons and Health Check — How to Prepare and Respond

Quick answer: GST departmental enforcement runs on four tracks: audit by tax authorities (Section 65, with a special audit by a chartered accountant under Section 66), assessment (self-assessment, scrutiny of returns, best-judgement and provisional assessments under Sections 59 to 64), investigation by the Directorate General of GST Intelligence (searches under Section 67 and summons under Section 70) and adjudication on a show-cause notice. Each has its own notice, forms and time limits, and statements recorded under a summons are evidence. Arrest is possible only for offences classed cognisable and non-bailable, which means tax of more than ₹5 crore. A GST health check before any notice arrives — reconciling GSTR-1, GSTR-3B, 2B and the books — is the cheapest defence.

Frequently asked questions

What is a GST audit by the department?

An examination of your records and returns by tax officers under Section 65, started by a notice in Form ADT-01 and normally completed within three months, extendable.

What is a special audit under GST?

An audit by a chartered or cost accountant nominated by the department under Section 66 where the value or nature of transactions is complex or suspected to be undervalued.

What is ASMT-10?

A notice of discrepancies found on scrutiny of your returns under Section 61; you reply in Form ASMT-11 within 30 days, with a reconciliation.

Must I attend a DGGI summons?

Yes — a summons under Section 70 is legally binding, and a statement recorded there is evidence; attend with an advisor and review the statement before signing.

Can I be arrested under GST?

Only for offences that are cognisable and non-bailable, which involve tax of more than ₹5 crore, and subject to the Commissioner's authorisation and the person's legal rights.

What is a GST health check?

A pre-notice review reconciling GSTR-1, GSTR-3B, GSTR-2B and the books to find ITC, turnover and classification gaps before the department does.

What is the difference between audit and assessment?

Audit is an examination of records at your premises under Section 65; assessment is the determination of tax liability under Sections 59 to 64.

What should I do if DGGI visits my premises?

Stay calm, ask for the authorisation, call your advocate, do not sign blank papers, take copies of anything seized and read every statement before signing.
