Input Tax Credit denial is the single largest category of GST disputes in India. From GSTR-2A mismatches to supplier default to retroactive registration cancellation, the department has denied ITC on grounds that multiple High Courts have consistently rejected when the underlying transaction is genuine. Now, with GSTAT operational, these disputes finally have a dedicated second-appeal forum.
This guide covers the 8 most common ITC denial grounds, the High Court precedents that favour taxpayers, the specific evidence strategy for each ground, and the practical process of filing and winning an ITC denial appeal at GSTAT. For the general GSTAT filing process, see how to file a GSTAT appeal (know more). For the deadline details, see our backlog deadline guide (know more).
The 8 Most Common ITC Denial Grounds and How to Beat Each One
Ground 1: GSTR-2A/2B Mismatch - Supplier Did Not File Returns
What happens: You claimed ITC in GSTR-3B based on tax invoices received. The supplier did not file GSTR-1 or GSTR-3B. Your ITC does not appear in GSTR-2A/2B. The department issues a DRC-01C mismatch notice and ultimately denies the ITC.
Why this is wrong: Section 16(2) lists four conditions for ITC: (a) possession of tax invoice, (b) receipt of goods/services, (c) tax actually paid to government, (d) return filed by recipient. The recipient has fulfilled (a), (b), and (d). Condition (c)-that tax be paid to the government-is the supplier’s obligation, not the buyer’s.
HC precedent: Calcutta HC (D.Y. Beathel Enterprises): ITC cannot be denied to a bona fide buyer when the seller defaults on tax payment. The remedy lies against the supplier under S.79, not against the compliant recipient. Madras HC (similar): a business cannot be debarred from ITC because the supplier did not pay GST. Kerala HC: ITC cannot be denied solely because the transaction is not reflected in GSTR-2A.
Evidence strategy: Tax invoices with complete details, e-way bills showing goods movement, bank statements showing payment to supplier through banking channels (not cash), stock registers showing receipt, and consumption/production records showing use. If you have all five, your case is strong regardless of the GSTR-2A status.
Ground 2: Supplier’s GST Registration Cancelled Retrospectively
What happens: You purchased from a supplier who was registered at the time of the transaction. Later, the department cancelled the supplier’s registration retrospectively (effective from a date before your transaction). The department then denies your ITC on the ground that you purchased from an “unregistered person.”
Why this is wrong: At the time of the transaction, the supplier WAS registered. The buyer verified the registration on the GST portal. Retrospective cancellation is an administrative action against the supplier that cannot penalise a bona fide buyer who had no knowledge of the future cancellation.
HC precedent: HP HC (Himalaya Communication, June 2025): ITC cannot be denied solely on the ground of retrospective cancellation without examining the genuineness of the transaction. Delhi HC: customers are entitled to ITC even if the supplier’s registration was subsequently cancelled. SC (VAT context): ITC cannot be denied when the seller was registered at the time of transaction and the purchase was genuine.
Evidence strategy: Screenshot of the supplier’s GST portal profile showing “Active” status at the time of transaction (if you saved it), the tax invoice with valid GSTIN, payment through banking channels, and e-way bill. The key argument: the buyer’s due diligence at the time of purchase was complete.
Ground 3: Section 16(4) Time Limit Expired
What happens: You claimed ITC after the time limit under Section 16(4)-the earlier of the due date of return for September following the end of the FY, or the date of filing the annual return.
Key development: The Finance (No. 2) Act, 2024 retrospectively inserted Section 16(5), extending the time limit for availing ITC for certain FYs (2017-18 to 2020-21). This was specifically enacted to address the hardship caused by the non-availability of GSTAT and the pandemic-related disruptions. If your ITC denial relates to FY 2017-18 through 2020-21, Section 16(5) may restore your ITC eligibility.
Evidence strategy: Show that the ITC was genuine (invoices, payments, receipt of goods/services). Cite Section 16(5) if applicable. Argue that Section 16(4) is procedural, not substantive-ITC is a vested right that cannot be denied for procedural non-compliance when the underlying transaction is genuine (Calcutta HC: ITC is a vested right).
Ground 4: Blocked Credit under Section 17(5)
What happens: The department denies ITC on goods/services listed under Section 17(5) as “blocked credit”: motor vehicles, food and beverages, membership of clubs, personal consumption, construction of immovable property, etc.
Where the dispute lies: The exceptions within S.17(5) itself. For example: motor vehicles are blocked EXCEPT when used for transportation of goods, making further supply of vehicles, or providing transportation service. Construction of immovable property is blocked EXCEPT plant and machinery. The dispute often centres on whether the specific use qualifies for the exception.
HC precedent: SC (Safari Retreats, Mar 2025): GST on construction of commercial property used for business (leasing) can qualify as “plant” under the functionality test. The term “plant and machinery” cannot be given a restricted meaning. This opened the door for construction ITC claims where the building functions as “plant.” Delhi HC (B Braun Medical): set aside ITC denial, allowing the taxpayer to claim ITC on inputs used for constructing a facility that qualifies as plant.
Evidence strategy: Demonstrate that your specific use falls within the exception. For motor vehicles: show the vehicle is used for goods transportation (log books, trip records). For construction: show the building functions as “plant” per the Safari Retreats functionality test. Detailed functional analysis is essential.
Ground 5: DRC-01C Mismatch Notice - GSTR-3B vs GSTR-2B Difference
What happens: From July 2025, DRC-01C is automated and hard-locked with GSTR-3B. If ITC claimed in GSTR-3B exceeds the ITC available in GSTR-2B, the system generates an automated notice. The taxpayer must either reduce the ITC or explain the difference. If not resolved, the excess ITC is denied.
Common causes: Timing differences (supplier filed GSTR-1 late, so the invoice appears in a later period’s GSTR-2B), credit notes not processed by supplier, debit notes creating additional ITC not yet reflected, and genuine errors in GSTR-2B data.
Evidence strategy: Prepare a month-by-month reconciliation of GSTR-3B ITC claimed vs GSTR-2B ITC available. Show that the cumulative ITC over 12 months matches-the mismatch is a timing difference, not an excess claim. Attach supplier invoices, GSTR-1 filing dates, and credit/debit note trail. At GSTAT, present this reconciliation as a comprehensive exhibit.
Ground 6: Rule 86A - ITC Blocked in Electronic Credit Ledger
What happens: The Commissioner, based on reasons to believe, blocks (restricts) the ITC available in your electronic credit ledger under Rule 86A. The blocked ITC cannot be used for payment of output tax. The block is valid for 1 year.
Key legal point: Rule 86A(3) mandates that the restriction shall cease to have effect after 1 year from the date of imposition. If the department has not initiated proceedings under S.73/74 within that year, the ITC must be unblocked automatically. Bombay HC has directed the department to release blocked ITC of Rs 1.17 crore after 1 year when the department failed to complete verification.
Evidence strategy: If the block has exceeded 1 year without proceedings: cite Rule 86A(3) and Bombay HC precedent. If proceedings are initiated: challenge the substantive denial on the merits of the transaction (genuine purchase, payment, receipt). Rule 86A is a temporary measure-the substantive ITC eligibility is determined under S.16/17.
Ground 7: Fake ITC / Fraudulent Invoice Allegations
What happens: The department (often DGGI) alleges that the invoices on which you claimed ITC are “fake”-issued without actual supply of goods/services. These cases involve S.74 (fraud/wilful misstatement) demands with 100% penalty.
Where the defence lies: The burden of proving fraud is on the department. The department must show that no supply actually took place-not merely that the supplier was non-compliant. If you can demonstrate goods movement (e-way bills, transporter records, weighbridge slips), payment (bank transfers, not cash roundtripping), and use of goods (stock records, production/consumption), the “fake invoice” allegation collapses.
Evidence strategy: This is the highest-evidence category. Prepare: e-way bills with vehicle numbers, transporter receipts, weighbridge slips, warehouse receipts, stock registers, production records, quality inspection reports, bank transfer records (showing no cash-back loop), and any communication with the supplier (purchase orders, delivery challans, emails). At GSTAT, present a complete supply chain trail. Cite Sterling & Wilson for GSTAT’s power to independently evaluate this evidence.
Ground 8: ITC on Imports Not Reflected in Portal
What happens: You imported goods, paid IGST at customs, but the ITC does not appear in your electronic credit ledger on the GST portal. The department denies the ITC because it is not reflected in the system.
HC precedent: Calcutta HC (Amar Iron Udyog, Jan 2026): ITC on imports cannot be denied merely due to non-reflection in the GST portal when IGST payment is confirmed by customs authorities. The portal’s failure to reflect the credit is a system issue, not a legal ground for denial.
Evidence strategy: Bill of Entry, customs duty payment receipt (showing IGST paid), ICEGATE records, and bank debit confirming the customs duty payment. If the customs system confirms IGST was paid, the GST portal’s non-reflection is a technical problem that cannot deny a substantive right.
Building Your Evidence Package for GSTAT
GSTAT has full factual evaluation power (Sterling & Wilson, 14 February 2026). This means the bench will re-examine evidence that the First Appellate Authority may have dismissed or inadequately considered. Your evidence package must be comprehensive, organised, and indexed.
| Evidence Type | What It Proves | Where to Get It |
|---|---|---|
| Tax invoices | Supply was invoiced with valid GSTIN, HSN, tax amount | Your purchase records / accounts payable |
| E-way bills | Goods were actually transported from supplier to your premises | GST portal / e-way bill portal |
| Bank statements | Payment was made through banking channels (not cash roundtrip) | Your bank |
| Stock / inward registers | Goods were received at your premises | Your warehouse / inventory system |
| Production / consumption records | Goods were used in your business operations | Your manufacturing / operations records |
| Supplier’s GSTR-1 (if available) | Supplier reported the invoice in their outward supply return | GST portal / GSTR-2A/2B |
| Supplier portal screenshot | Supplier was registered and active at the time of transaction | Screenshot from gst.gov.in (date-stamped) |
| Transporter records | Physical movement of goods: vehicle number, date, route, weight | Transporter / logistics partner |
| Purchase orders / contracts | Commercial arrangement existed before the supply | Your procurement files |
| Quality inspection reports | Goods were inspected and found conforming on receipt | Your quality / stores department |
Pre-Deposit for ITC Denial Appeals
The pre-deposit for ITC denial appeals is calculated on the disputed tax amount:
If ITC denied = Rs 10 lakh: The department’s demand is Rs 10 lakh (the ITC they reversed) + interest + penalty. Pre-deposit: 20% of Rs 10 lakh = Rs 2 lakh (cumulative: Rs 1 lakh at S.107 + additional Rs 1 lakh at GSTAT). Court fee: Rs 10,000. Total GSTAT filing cost: approximately Rs 1.1 lakh (additional deposit + court fee). Use our GSTAT pre-deposit calculation (know more) tool for exact computation.
S.128A Amnesty Scheme interaction: For ITC demands under Section 73 (non-fraud) for FY 2017-18 to 2019-20, the amnesty scheme under Section 128A waives interest and penalty if the full tax is paid by the specified date. Evaluate whether paying under amnesty is cheaper than appealing. For demands you believe are fundamentally wrong (genuine ITC denied on wrong grounds), appealing at GSTAT gives you the chance to recover the entire amount. For borderline cases, amnesty may be the pragmatic choice.
The ITC Appeal Lifecycle at GSTAT
| Stage | What Happens | Your ITC-Specific Action |
|---|---|---|
| 1 | File APL-05 | Grounds of appeal: cite specific S.16/17 provisions, HC precedents, and the evidence the First Appellate Authority ignored. Attach the complete evidence package. |
| 2 | Admission | Ensure pre-deposit proof and all documents are complete. Deficiency in ITC cases usually involves missing invoice copies or reconciliation sheets. |
| 3 | Department’s reply | Read carefully: the department will justify the denial. Identify factual errors, missing investigation at your premises, and reliance on GSTR-2A alone. |
| 4 | Your rejoinder | Address each department argument point-by-point. Present the reconciliation showing cumulative ITC matches. Cite HC precedents for each denial ground. |
| 5 | Hearing | Present the supply chain trail (invoice → e-way bill → payment → receipt → consumption). The Technical Members will focus on the computation; Judicial Members on the legal principles. Address both. |
| 6 | Order | If allowed: claim refund of pre-deposit + ITC restored to credit ledger. If remanded: the lower authority must re-examine with GSTAT’s directions. |
Key Takeaways
ITC denial is the largest category of GST disputes expected at GSTAT. The 8 most common grounds are: GSTR-2A/2B mismatch, supplier retroactive cancellation, S.16(4) time limit, S.17(5) blocked credit, DRC-01C mismatch, Rule 86A blocking, fake invoice allegations, and import ITC non-reflection.
For each ground, strong HC precedent favours the taxpayer when the underlying transaction is genuine. The common thread: ITC is a substantive right. Denial requires evidence of non-genuine transactions, not merely supplier default or system non-reflection. The burden of proving fraud is on the department.
The evidence package is everything. Tax invoices + e-way bills + bank payments + stock records + consumption records = a complete supply chain trail that defeats most ITC denial arguments. Prepare this package at the GST notice response (know more) stage itself-not after the first appeal fails.
GSTAT’s factual evaluation power (Sterling & Wilson) means evidence that was ignored at the first appeal can be re-examined. File before 30 June 2026 for all pre-April 2026 orders. Pre-deposit: 20% of denied ITC amount (cumulative). Court fee: Rs 1,000/lakh (max Rs 25,000).
