Short answer: yes, you can reply to most GST notices without a CA. The majority of notices — DRC-01B, DRC-01C, ASMT-10, REG-03 — are factual queries where you explain a discrepancy and cite the relevant CGST rule. No legal argument required.
A CA is only necessary for complex cases: large demand notices under Section 74 (fraud/suppression), appeals, or adjudication proceedings. For everything else, you reply on the GST portal yourself and the matter closes.
This guide walks you through exactly which notices you can handle yourself, the step-by-step process, and when to get help.

What Information You Need Before You Reply
Before you start, collect these details from the notice PDF (available at GST portal → Services → User Services → View Notices and Orders):
- Notice type — DRC-01B, ASMT-10, etc. (printed at the top of the notice)
- Your GSTIN
- Name of issuing officer and their office address
- The period of mismatch — e.g. "April 2024 to March 2025"
- The specific discrepancy amount or allegation
- Your explanation — why the mismatch happened (timing difference, supplier error, input credit reversal, etc.)
Step-by-Step: Reply to a GST Notice Without a CA
Open the notice PDF from the GST portal. The notice type (DRC-01B, ASMT-10, etc.) is in the subject line and at the top of the document. Note the deadline — it is usually 7, 15, or 30 days from the notice date.
Go to GST Reply AI. Select the notice type, enter your GSTIN, officer name, and a brief explanation of the discrepancy. The AI generates a legally cited reply in 30 seconds — citing the exact CGST rule and Act section applicable to your notice type.
Check that your GSTIN, officer name, and explanation are accurate. The legal citations (Rule 88C, Section 61, etc.) are auto-generated and correct — you don't need to verify those unless you want to.

DRC-01B and DRC-01C
Once you submit a valid DRC-01B or DRC-01C reply on the portal, GSTR-1 filing is unblocked within 1 business day. The mismatch is noted but no demand is raised if you've given a satisfactory explanation. If the officer is unsatisfied, they may issue a follow-up SCN — but that happens only for large or suspicious discrepancies.
ASMT-10
The officer reviews your reply within 30–60 days. If satisfied, they close the matter by issuing an ASMT-12 (acceptance letter). If not, they may issue an SCN under Section 73 for the specific amounts in dispute.
REG-03
Submit supporting documents with your reply (address proof, lease deed, electricity bill, etc.). If accepted, your GST registration is approved or reinstated. Response time is typically 7–15 working days.
When Do You Need a CA?
- Demand above ₹10 lakh — Even a DIY reply can trigger adjudication. A CA can negotiate and argue against demand confirmation.
- Section 74 (fraud/suppression) — Allegations of deliberate evasion require professional legal strategy, not just factual explanation.
- GST appeals — Appeals before the Appellate Authority or GSTAT need legal representation.
- Complex ITC reversals — Multiple years of input credit disputes across many suppliers need reconciliation expertise.
- If you receive a summons (Section 70) — Always consult a CA or GST advocate before appearing.
