DRC-01C — The 7-Day ITC Notice That Punishes Slow Responses

Quick answer: Reply to DRC-01C within 7 days: GST portal → Services → Returns → Return Compliance → DRC-01C → Part B — either pay the excess ITC with interest via DRC-03, or explain the GSTR-2B vs 3B gap with documents. No reply = your next GSTR-1/IFF gets blocked under Rule 59(6).

DRC-01C is not written by an officer — the GST system generates it automatically after your GSTR-3B, whenever the ITC you claimed exceeds what GSTR-2B shows beyond the threshold. It gives you seven days. Not thirty. Seven. And it will keep coming every cycle until the underlying gap is explained or fixed.

Prevention tip: Rule 36(4) already caps provisional claims — the cleanest discipline is claiming ITC from GSTR-2B each month rather than books alone. That single habit ends the DRC-01C cycle.

Valid explanations the system accepts

Supplier filed late — the invoice will appear in a later 2B; identify each invoice and supplier GSTIN.
Prior-period claims — ITC from earlier months claimed now within the Section 16(4) window; reference the original invoice dates.
Credits outside 2B's scope — imports (Bill of Entry), reverse charge self-invoices, ISD credits — legitimately claimable yet absent from 2B.
Genuine excess — where a real error exists, payment through DRC-03 with the reply closes the matter cleanly and cheaply.

Our 7-day response protocol

Day 1: pull the notice, GSTR-2B, GSTR-3B and purchase register; quantify the exact gap.
Day 2–3: invoice-level mapping of every rupee of difference into the valid categories above; supplier follow-ups where filing gaps exist.
Day 4–5: draft the portal reply with a reconciliation annexure; DRC-03 payment for any true excess.
Day 6: file, archive the acknowledgment, and set up the monthly 2B discipline that prevents a repeat.

Why speed matters beyond the deadline: an unanswered DRC-01C can restrict your GSTR-1 filing — which blocks your buyers' ITC — turning a compliance notice into a customer-relations problem. The reply protects your receivables, not just your credit.

Seven days. That's the entire window. Move now.

Frequently asked questions

Why did I get a DRC-01C when my ITC claim is genuine?

DRC-01C is machine-generated under Rule 88D whenever GSTR-3B ITC exceeds GSTR-2B by more than the threshold (₹1 lakh or 20%, whichever is lower). Genuine causes — supplier filed late, prior-period invoices claimed now, imports/RCM credits not in 2B — all trigger it. The notice asks for explanation, not admission.

What happens if I miss the 7-day DRC-01C deadline?

Consequences can include restriction on filing GSTR-1 for subsequent periods and escalation toward demand proceedings — the portal is built to force a response. Treat day one as the deadline.

How do I reply to DRC-01C on the portal?

Log in → Services → Returns → DRC-01C. For each excess amount, either pay through DRC-03 or select the applicable reason with invoice-level details. A reconciliation annexure (2B vs 3B vs purchase register) uploaded with the reply is what makes it stick.

How do I stop getting DRC-01C every month?

Claim ITC from GSTR-2B rather than books alone, chase suppliers who file late, track prior-period claims separately, and reconcile before every GSTR-3B — a monthly 2B discipline ends the notice cycle.
