GST ITC Mismatch Notice: GSTR-2B vs Claimed Input Tax Credit
Last reviewed: March 2025 · Sourced from official government portals
WHY YOUR ITC CLAIM IS BEING QUESTIONED
Since the Finance Act 2022 amended Section 16(2)(aa) of the CGST Act, Input Tax Credit can only be availed if the invoice or debit note appears in your GSTR-2B. GSTR-2B is an auto-generated document showing all the ITC available to you based on what your suppliers have actually filed in their GSTR-1.
The problem: You may have received goods or services, paid for them, and have the invoice - but if your supplier did not file their GSTR-1 correctly, or filed it late, the credit will not appear in your GSTR-2B. And you claimed it anyway. That gap is what the department is now targeting.

HOW THESE NOTICES ARRIVE AND WHAT THEY LOOK LIKE
ITC mismatch notices come in different forms depending on the stage:
- •ASMT-10 scrutiny notice: The most common form. Officer identifies that your GSTR-3B claimed ITC is higher than your GSTR-2B available ITC and asks for an explanation.
- •DRC-01B: As described separately, the system flags GSTR-1 vs 3B differences which can include ITC-related mismatches.
- •DRC-01: If the ASMT-10 reply is not satisfactory, a formal demand for the excess ITC claimed is raised.
- •GST Audit observation: During an audit under Section 65, ITC mismatches are a primary focus area.
BUILDING YOUR RESPONSE
Your defence against an ITC mismatch notice has multiple layers:
- •Reconcile first: Before responding, do a proper reconciliation of your claimed ITC vs GSTR-2B. Identify exactly which invoices are missing from GSTR-2B and why.
- •Supplier communication: For every missing invoice, contact the supplier and ask them to rectify their GSTR-1. Once they amend, the credit will appear in a future GSTR-2B and can be claimed. Document your communication attempts.
- •Establish receipt of goods/services: Under Section 16(2)(b), ITC is available only on receipt of goods or services. Even if GSTR-2B does not reflect the credit, you can argue that the credit is legally available if you can prove actual receipt, payment, and tax was charged.
- •Court precedents in your favour: Multiple High Courts have held that a buyer should not be denied ITC solely because their supplier was non-compliant, especially if the buyer took all reasonable steps. This is an evolving legal position and should be part of your reply.
- •Reverse matching with purchases: Show your full purchase ledger for the period and match it with GSTR-2B. This demonstrates that the mismatch is limited to specific supplier non-compliance, not a broad pattern.
The legal position on ITC denial for supplier default is actively being litigated. As of 2025, buyer-favourable positions exist in several High Courts. A CA can advise on applicable precedents for your jurisdiction.
WHAT TO DO GOING FORWARD
Beyond resolving the current notice, here is how to protect your ITC going forward:
- •Match GSTR-2B before filing GSTR-3B every month: Only claim ITC that appears in GSTR-2B. If you have credits not in GSTR-2B, hold them until they appear.
- •Include ITC matching as a vendor selection criterion: Prefer suppliers who file on time. Persistent non-filer suppliers cost you ITC and create litigation risk.
- •Use 2B reconciliation tools: Accounting software like Tally, Zoho, and Busy now have GSTR-2B reconciliation built in. Use them.
- •Document receipt of goods: Maintain good inward supply registers and delivery acknowledgements. These are your evidence if ITC is challenged.
Frequently Asked Questions
My supplier promised to file their GSTR-1 but has not done it in 3 months. Can I claim the ITC now?
As of the current law, strictly speaking, no - the credit must appear in your GSTR-2B before it can be claimed. However, if the supplier eventually files and the credit appears in a future GSTR-2B, you can claim it in the period it appears. Keep your purchase records and the credit note/invoice ready for whenever this happens.
I reversed the ITC mismatch amount in a subsequent month. Does this close the notice?
If you voluntarily reversed the ITC in the same year (or subsequent month) through a GSTR-3B reversal, this demonstrates that you are correcting the position. Include this reversal with challan details in your notice reply. Pay interest at 24% p.a. from the date of claiming incorrect ITC to the date of reversal (higher rate applies when ITC is reversed pursuant to demand).
