Received a GST notice? Types of notices and how to reply

ASMT-10, DRC-01A, DRC-01, DRC-01B/01C, REG-17 – what each notice means, the time limit to reply and the mistakes to avoid.

By CA Dilbagh Singh, Chartered Accountant, Rohini, Delhi Β· Published 5 November 2026

A GST notice is not always a demand. Many notices only ask you to explain a mismatch, and a clear, documented reply at that stage often closes the matter. Trouble usually starts when a notice is ignored, the reply window passes, or a reply is filed without supporting working. Below are the notices our Rohini office sees most often, what each one means and how to respond.

First steps when a GST notice arrives

  • Download the notice from the GST portal (Services β†’ User Services β†’ View Notices and Orders) and note the reference number, date and section.
  • Note the reply due date printed on the notice – the portal reply must be filed before it.
  • Identify the period and the issue: return mismatch, input tax credit (ITC), e-way bill, registration or audit.
  • Collect GSTR-1, GSTR-3B, GSTR-2A/2B, GSTR-9/9C, purchase and sales registers, e-way bills and bank statements for that period.
  • Do not pay or accept a liability in a hurry. First reconcile the figures and check whether the difference is real.

Common GST notices and what they mean

ASMT-10 – scrutiny of returnsIssued under Section 61 when the officer finds discrepancies in your returns. Reply in Form ASMT-11 with an explanation and reconciliation, normally within 30 days. If the reply is accepted, the matter is closed in ASMT-12.Sec 61 Β· Rule 99
DRC-01B – GSTR-1 vs GSTR-3BSystem intimation when tax declared in GSTR-1 exceeds tax paid in GSTR-3B beyond the prescribed limit. Pay the difference through DRC-03 or explain it in Part B. An unanswered DRC-01B can block filing of your next GSTR-1.Rule 88C
DRC-01C – ITC claimed vs GSTR-2BIntimation when ITC claimed in GSTR-3B exceeds ITC available in GSTR-2B. Explain with a supplier-wise reconciliation or reverse the excess credit.Rule 88D
DRC-01A – pre-show-cause intimationCommunicates the tax, interest and penalty proposed before a formal show-cause notice. You can pay fully or partly through DRC-03, or file objections in Part B.Rule 142(1A)
DRC-01 – show-cause noticeThe formal demand notice. For FY 2017-18 to 2023-24 it is issued under Section 73 (no fraud) or Section 74 (fraud or suppression); from FY 2024-25 onwards both are covered by Section 74A. Reply in DRC-06 and ask for a personal hearing.Sec 73 Β· 74 Β· 74A
REG-17 – cancellation of registrationProposes cancellation of GST registration, for example for non-filing of returns. Reply in REG-18 within the time given. If registration is already cancelled, apply for revocation in REG-21.Sec 29 Β· 30
ADT-01 – departmental auditIntimation that the department will audit your records under Section 65. Keep books, returns and reconciliations ready; findings are communicated in ADT-02.Sec 65

How to draft a reply that works

  • Answer every point. Take each allegation or figure in the notice and respond to it separately, with numbers.
  • Attach a reconciliation. Most notices arise from differences between GSTR-1, GSTR-3B, GSTR-2B and the books. A month-wise, supplier-wise working is the strongest evidence.
  • Support it with documents – invoices, e-way bills, debit/credit notes, bank proof of payment to suppliers, and amendments made in later returns.
  • Cite the law correctly – the relevant section, rule, circular or court decision where it supports your position.
  • Ask for a personal hearing on a show-cause notice. Section 75(4) requires a hearing where you request one or where an adverse decision is contemplated.
  • Keep proof of filing – save the acknowledgement of every reply filed on the portal.

Paying early can reduce or remove penalty

In a show-cause notice that does not allege fraud or suppression, paying the tax with interest within 60 days of the notice generally concludes the proceedings without penalty. In fraud or suppression cases the penalty is reduced, not removed, the earlier you pay. Whether to pay or contest depends on the strength of your documents – take that decision with your reconciliation in hand.

If the order goes against you

An adverse order in DRC-07 can be appealed before the Appellate Authority in Form APL-01 within three months, with a pre-deposit of 10% of the disputed tax. A further appeal lies to the GST Appellate Tribunal (GSTAT). Errors apparent on the record can be corrected through rectification under Section 161.

Frequently asked questions

What happens if I do not reply to a GST notice?

The officer can decide the matter on the basis of available records, raise a demand with interest and penalty, and in some cases restrict return filing or cancel registration. Always reply, or ask for more time in writing, before the due date.

Can I ask for more time to reply?

Yes. Request an adjournment through the portal or in writing, giving reasons. Section 75(5) limits adjournments to three during proceedings, so use them carefully.

Who can reply to a GST notice on my behalf?

You can reply yourself, or authorise a chartered accountant or other authorised representative under Section 116 to draft the reply and appear at the hearing.
