Quick Answer
Input Tax Credit denial due to GSTR-2B mismatch is the single largest category of GST disputes in India. The department denies ITC under Section 16(2)(c) of the CGST Act when the supplier has not uploaded invoices in GSTR-1 or has not paid the tax collected. At Virtual Auditor, we have handled 200+ ITC denial matters. Our approach: systematic reconciliation of GSTR-2A/2B versus books, documentation of genuine receipt and payment, and leveraging High Court precedents that protect bonafide buyers. Pre-deposit for Section 107 appeal: 10% of disputed ITC amount.
Definition — Input Tax Credit (ITC): Under Section 16(1) of the CGST Act, every registered person is entitled to take credit of the input tax charged on any supply of goods or services which are used or intended to be used in the course or furtherance of business. ITC is the mechanism that makes GST a value-added tax — you pay tax only on the value you add, not on the full sale price.
Definition — GSTR-2B: An auto-drafted ITC statement generated on the 14th of each month based on the supplier’s GSTR-1 and GSTR-5 filings. It is a static statement (unlike the dynamic GSTR-2A) and serves as the basis for ITC eligibility under Rule 36(4) from 01-01-2022 onwards. If an invoice does not appear in GSTR-2B, the ITC on that invoice is treated as ineligible by the system.
Definition — Rule 36(4): Rule 36(4) of the CGST Rules restricts the ITC availed in GSTR-3B to the ITC available in GSTR-2B. From 01-01-2022 (amended by Notification No. 40/2021-Central Tax dated 29-12-2021), no excess ITC over GSTR-2B is permissible. Earlier, 5% excess over GSTR-2A was allowed.
Section 16(1) of the CGST Act grants every registered person the right to take credit of input tax charged on inward supplies used in the course or furtherance of business. This is not a concession or benefit — it is a statutory entitlement that flows from the constitutional structure of GST as a value-added tax. The right to ITC is subject to conditions and restrictions prescribed under Section 16(2) and Section 17.
ITC can be availed only when all four conditions under Section 16(2) are simultaneously satisfied:
The legal battleground in GSTR-2B mismatch cases is almost always Section 16(2)(c). The department’s position: if the supplier has not filed GSTR-1 or GSTR-3B, the tax has not been paid to the Government, therefore condition (c) is not satisfied, therefore ITC must be reversed. The taxpayer’s counter-argument: the buyer paid the tax to the supplier as part of the invoice value, the buyer has no mechanism to verify or enforce the supplier’s return filing, and penalising the buyer for the supplier’s default violates Article 14 and Article 19(1)(g) of the Constitution.
ITC in respect of any invoice or debit note must be availed by the earlier of: (a) the 30th of November following the end of the financial year to which the invoice pertains, or (b) the date of filing the annual return under Section 44 for that financial year. This deadline was amended from September to November by the Finance Act 2022 with effect from 01-10-2022. For FY 2024-25 invoices, the ITC claim deadline is 30th November 2025 or the date of filing GSTR-9 for FY 2024-25, whichever is earlier.
Missing the Section 16(4) deadline is fatal — there is no mechanism to claim ITC after this date, irrespective of the genuineness of the transaction. At Virtual Auditor, we include Section 16(4) deadline tracking as part of our monthly compliance review for all retainer clients.
Before analysing GSTR-2B mismatch disputes, it is essential to confirm that the ITC in question is not blocked under Section 17(5). If the credit falls within the blocked category, the mismatch is irrelevant — the ITC was never available. Section 17(5) denies ITC on the following categories:
We have seen cases where the department issues a mismatch-based demand, but the underlying ITC was also blocked under Section 17(5). In such cases, the taxpayer faces a double denial. Our advice: before contesting the mismatch, verify that the ITC does not fall within any blocked category. If it does, the litigation cost is wasted.
Rule 36(4) has undergone significant amendments since GST inception:
| Period | Rule 36(4) Threshold | Notification |
|---|---|---|
| 01-07-2017 to 08-10-2019 | No restriction — ITC as per books | N/A |
| 09-10-2019 to 31-12-2019 | GSTR-2A + 20% excess allowed | Notification No. 49/2019-CT dated 09-10-2019 |
| 01-01-2020 to 31-12-2020 | GSTR-2A + 10% excess allowed | Notification No. 75/2019-CT dated 26-12-2019 |
| 01-01-2021 to 31-12-2021 | GSTR-2A/2B + 5% excess allowed | Notification No. 94/2020-CT dated 22-12-2020 |
| 01-01-2022 onwards | Restricted to 100% of GSTR-2B — zero tolerance | Notification No. 40/2021-CT dated 29-12-2021 |
The progressive tightening from 20% excess to zero tolerance means that from January 2022, every rupee of ITC claimed must be supported by a corresponding entry in GSTR-2B. Any excess is automatically flagged by the system and will trigger a DRC-01 notice.
The mismatch between ITC claimed in GSTR-3B and ITC available in GSTR-2B arises due to the following reasons:
The department follows a systematic process for ITC denial based on GSTR-2B mismatch:
Based on our experience at Virtual Auditor, the most common grounds cited by officers in ITC denial SCNs:
The first step in any ITC denial defence is a thorough, invoice-level reconciliation between ITC claimed in GSTR-3B, ITC available in GSTR-2B, ITC reflected in GSTR-2A, and ITC as per the purchase register/books of account. This reconciliation must be done for every return period covered by the SCN. At Virtual Auditor, we use automated reconciliation tools that match invoices across all four data sets and flag discrepancies with reasons.
The reconciliation typically reveals: (a) invoices present in books but absent from GSTR-2B (genuine mismatch — the core dispute), (b) invoices present in GSTR-2B but not claimed in GSTR-3B (excess credit available — partial offset), (c) timing differences where the supplier uploaded the invoice in a subsequent period, and (d) computational errors in the department’s demand calculation.
Not all mismatches are equal. We classify each mismatch invoice into one of five categories, each requiring a different defence approach:
For each mismatch invoice, compile the following documentary evidence:
The legal position on ITC denial for GSTR-2B mismatch is evolving rapidly, with multiple High Courts ruling in favour of bonafide buyers. Key precedents we rely on:
In favour of the taxpayer:
CBIC Circulars:
For each category of mismatch, we compute the expected outcome of litigation versus voluntary payment. This is critical for cash flow planning and management decision-making:
| Mismatch Category | Win Probability | Recommendation |
|---|---|---|
| A — Supplier delay (GSTR-3B paid) | 80-90% | Contest — strong position |
| B — Filing error (correctable) | 70-80% | Get supplier to amend, then contest |
| C — Supplier non-compliant | 50-70% | Contest with strong documentation |
| D — Supplier cancelled (pre-cancellation invoices) | 60-75% | Contest with cancellation date proof |
| E — Bogus supplier | 10-20% | Accept — pay under Section 73(5) or 74(5) |
The reply to the SCN must be filed in Form DRC-06 within 30 days of service of the notice. The reply structure we follow at Virtual Auditor:
If the adjudicating authority confirms the demand despite a well-argued reply, the appeal route under Section 107 must be activated within 3 months (extendable by 1 month on sufficient cause). Pre-deposit: 10% of disputed ITC (tax only — not interest, not penalty). The appeal must be filed electronically in Form GST APL-01 on the GST portal.
For ITC denial cases involving substantial amounts or constitutional questions (such as the validity of Section 16(2)(c) as applied to bonafide buyers), a writ petition under Article 226 of the Constitution may be more effective than the statutory appeal route. The writ jurisdiction allows the High Court to examine the vires of Rule 36(4) and the interpretation of Section 16(2)(c) — issues that a statutory appellate authority may not address.
The most significant legal development in ITC law is the constitutional challenge to Section 16(2)(c). The provision requires that the tax charged on the supply must have been “actually paid to the Government.” The buyer pays the tax to the supplier as part of the invoice value. If the supplier does not remit this tax to the Government, the buyer’s ITC is denied — even though the buyer has no control over the supplier’s compliance.
Several High Courts have examined whether this provision violates:
The Finance Act 2024 introduced amendments to Section 16 by inserting a new sub-section 16(5) and 16(6), allowing retrospective ITC claims for FY 2017-18 to 2020-21 where the returns were filed before a specified date. This was a partial legislative acknowledgement that the rigid application of Section 16(4) caused genuine hardship. However, the core issue of Section 16(2)(c) — penalising buyers for supplier default — remains judicially alive.
A related category of ITC disputes involves proportional reversal under Rule 42 and Rule 43 of the CGST Rules. These rules apply when a registered person uses inputs or input services partly for taxable supplies and partly for exempt supplies or non-business purposes.
Rule 42 governs reversal for inputs and input services (other than capital goods). The formula computes the ratio of exempt turnover to total turnover, and the corresponding proportion of common ITC must be reversed. The computation is done monthly with an annual adjustment.
Rule 43 governs reversal for capital goods. ITC on capital goods used exclusively for exempt supplies or non-business purposes is fully blocked. ITC on capital goods used for both taxable and exempt supplies is allowed proportionally, with the reversal computed over the useful life of the asset (60 months or 20 quarters for immovable property).
Errors in Rule 42/43 reversal computation are common and are a frequent ground for ITC denial. The officer may compute the reversal differently from the taxpayer due to disagreements on: (a) what constitutes “exempt supply” (including non-GST supplies such as interest income, securities trading), (b) the correct turnover figures, or (c) the methodology for apportioning common credits. At Virtual Auditor, we have developed automated Rule 42/43 computation models that handle the monthly and annual adjustment calculations with audit-trail documentation.
When ITC denial stems from supplier non-compliance, the buyer should take active steps to pursue the supplier:
If the supplier subsequently files GSTR-1 and the invoice appears in the buyer’s GSTR-2B of a subsequent period, the buyer can reclaim the reversed ITC. As per Circular No. 170/02/2022-GST, the reclaim is made through Table 4A of GSTR-3B in the period in which the invoice appears in GSTR-2B. The reclaim is subject to the Section 16(4) time limit — if the deadline has passed, the ITC cannot be reclaimed even if the supplier files belatedly.
Section 122 of the CGST Act provides for penalties against persons who collect tax but fail to remit it to the Government. The buyer can file a complaint with the jurisdictional officer against the supplier for collecting GST on the invoice but not depositing it. While this does not directly restore the buyer’s ITC, it creates a documented record of the buyer’s bonafide conduct and puts pressure on the supplier to comply.
ITC denial demands can be substantial — ranging from a few lakhs to several crores. The pre-deposit requirement for appeal creates immediate cash flow pressure:
| Appeal Stage | Pre-Deposit | Reference |
|---|---|---|
| Section 107 — Appellate Authority | 10% of disputed tax | Section 107(6)(b) |
| Section 112 — Appellate Tribunal | Additional 10% (total 20%) | Section 112(8)(b) |
| High Court (Writ Petition) | No statutory pre-deposit (court may impose) | Article 226 |
Pre-deposit is computed on the tax amount only — not on interest under Section 50 or penalty under Section 73(9)/74(1). For an ITC denial of Rs 50 lakh, the Section 107 pre-deposit is Rs 5 lakh. If the first appeal fails and a Tribunal appeal is filed, an additional Rs 5 lakh is required (total Rs 10 lakh). The pre-deposit is refundable with interest under Section 115 if the appeal is allowed.

Practitioner Insight — CA V. Viswanathan
In my experience handling ITC disputes across multiple states, the single biggest mistake taxpayers make is treating the GSTR-2B mismatch as a binary — either the invoice is in GSTR-2B or it is not. The reality is far more nuanced. I have seen cases where the invoice was in GSTR-2A but not in GSTR-2B due to the timing of the snapshot. I have seen cases where the supplier paid the tax through GSTR-3B but did not upload invoices in GSTR-1. Each scenario demands a different legal argument and different documentary evidence. At Virtual Auditor (IBBI Registration: IBBI/RV/03/2019/12333), we do not take a one-size-fits-all approach. We classify every mismatch invoice, assign a win probability, compute the expected value of litigation versus settlement, and give you a clear recommendation. That is the difference between filing a reply and winning one.
Key Takeaways
Can ITC be denied solely because it does not reflect in GSTR-2B?
No. Multiple High Courts including Madras HC in Daga Global Chemicals (2024) and Calcutta HC in Suncraft Energy (2023) have held that ITC cannot be denied solely on the ground that the supplier failed to upload invoices in GSTR-1 causing GSTR-2B mismatch. The buyer must prove genuine receipt of goods/services, valid tax invoice, and actual payment to the supplier including GST component.
What are the four conditions under Section 16(2) for claiming ITC?
Section 16(2) requires: (a) possession of tax invoice or debit note, (b) receipt of goods or services, (c) tax actually paid to the Government by the supplier, and (d) furnishing of return under Section 39. All four conditions must be satisfied. Section 16(2)(c) is the most litigated condition in mismatch cases.
What is Rule 36(4) and how does it restrict ITC?
Rule 36(4) of CGST Rules restricts ITC availed in GSTR-3B to the amount reflected in GSTR-2B. Before 01-01-2022, a 5% tolerance was allowed over GSTR-2B amounts. From 01-01-2022 onwards, ITC is restricted to 100% of GSTR-2B — zero tolerance for excess claims. This rule was amended by Notification No. 40/2021-Central Tax dated 29-12-2021.
What is the time limit for claiming ITC under Section 16(4)?
ITC must be claimed by the earlier of: (a) 30th November of the year following the financial year to which the invoice pertains, or (b) the date of filing the annual return for that financial year. This was amended from the earlier ‘September’ deadline to ‘November’ by the Finance Act 2022.
How much does ITC denial appeal representation cost?
ITC mismatch reconciliation and reply drafting: from Rs 20,000. Section 107 appeal filing for ITC denial: from Rs 30,000. Tribunal (Section 112) appeal for ITC matters: from Rs 60,000. Writ petition drafting for constitutional challenge: from Rs 75,000. Contact Virtual Auditor at +91 99622 60333 for a case-specific assessment.
What documents are needed to defend an ITC denial?
Essential documents: (1) Original tax invoices from supplier, (2) E-way bills and lorry receipts proving movement of goods, (3) Bank statements showing payment to supplier including GST, (4) Goods receipt notes and stock register entries, (5) Purchase orders and contracts, (6) Supplier GSTN details and return filing status, (7) GSTR-2A/2B reconciliation statement, (8) Correspondence with supplier regarding return filing.
Can the department recover ITC from the buyer for the supplier’s default?
The department’s power to recover from buyer for supplier’s default is being challenged across High Courts. Section 16(2)(c) requires tax to be ‘actually paid to Government’ but the buyer has no control over supplier’s compliance. The buyer must demonstrate bonafide purchase, payment including GST, and no collusion with the supplier. Multiple HCs have held that the department must first proceed against the supplier.
