GST DISPUTES AND LEGAL REMEDIES

GST Input Tax Credit Denied: How Can You Challenge It?

A denial of input tax credit can increase your tax liability and disrupt working capital. The right remedy depends on why credit was questioned, the financial year involved and whether you have received a notice, a ledger-blocking direction or a final order.

What does input tax credit mean?

The Central Goods and Services Tax Act, 2017 (CGST Act) supplies the starting definitions. The following are plain-language summaries:

• Input tax - Section 2(62): Central, State, integrated or Union territory tax charged on supplies to a registered person, including specified reverse-charge tax and import IGST, but excluding composition tax.
• Input tax credit - Section 2(63): Credit of input tax.
• Input - Section 2(59): Goods other than capital goods used or intended for business.
• Input service - Section 2(60): A service used or intended for business.
• Capital goods - Section 2(19): Goods capitalised in the claimant's books and used or intended for business.

These definitions do not themselves establish eligibility. Section 16 conditions, Section 17 restrictions and the rules applicable to the relevant period must also be satisfied. Official legislation and guidance are listed below.

When is GST input tax credit available?

Under Section 16, credit generally requires a business-related supply, a prescribed tax document, receipt of goods or services, payment of the relevant tax to the Government and furnishing of the prescribed return. Where applicable, supplier-reported invoice details must be communicated to the recipient and credit must not be restricted under Section 38. An entry in GSTR-2B is therefore important but does not, by itself, establish every condition.

Section 17 restricts credit attributable to non-business or exempt use. Section 17(5) separately blocks specified credits, subject to its exceptions, including certain vehicle, personal consumption and construction expenses. Identify the exact clause before contesting denial: paying GST on an expense does not necessarily make its credit available.

Common reasons for denial and the first response

Older mismatch cases need a period-specific approach

Circular 183/15/2022-GST concerns specified GSTR-3B versus GSTR-2A differences for FY 2017-18 and FY 2018-19. Circular 193/05/2023-GST extends the prescribed verification approach to 1 April 2019 through 31 December 2021, subject to the applicable Rule 36(4) restrictions. Depending on the case and amount, supplier confirmation or a CA/CMA certificate may be relevant. These circulars are not a general exemption from the reporting conditions applicable from 1 January 2022.

Supplier default does not have one automatic answer

Separate a reporting mismatch from non-payment of tax, a non-existent supplier and an allegation of fictitious supply. Ask the officer to identify the invoice-wise material relied upon. Preserve evidence of actual receipt and payment, but do not assume that good faith alone overrides the statutory conditions. Any judgment relied upon should be checked for its facts, tax period, jurisdiction and subsequent appellate status.

Rule 37A addresses specified cases where the supplier reports the supply but does not furnish the corresponding GSTR-3B by 30 September following the financial year in which the recipient availed credit. The recipient's reversal deadline is generally 30 November following that financial year. The rule permits re-availment when the supplier subsequently furnishes the return; delayed reversal can attract interest.

Remedy 1: Reply to the notice with an invoice-wise defence

A discrepancy communication is not necessarily a final adjudication. Identify the proceeding and reply in the prescribed form: for example, ASMT-11 for a scrutiny notice or DRC-06 for a show-cause notice, as applicable. Follow the deadline in the communication and seek additional time with reasons if needed.

1. Identify the allegation: state the period, disputed amount, legal provision and precise reason for denial.
2. Prepare a reconciliation: map each disputed invoice to the purchase register, return, supplier reporting and evidence of receipt.
3. Answer both facts and law: explain eligibility, any applicable exception and errors in the officer's calculation.
4. Request relied-upon material: seek the statements, reports or other documents necessary to answer the allegation; request cross-examination where legally warranted.
5. Ask for a personal hearing: make the request in writing and retain the acknowledgement and all submissions.

Section 75(4) requires an opportunity of hearing when requested in writing or when an adverse decision is contemplated. Section 75(6) requires the order to explain the relevant facts and reasons. Section 75(7) prevents confirmation beyond the notice amount or on new grounds outside the notice.

For demand proceedings, Sections 73 and 74 concern periods up to FY 2023-24; Section 74A governs FY 2024-25 onwards. Fraud allegations, notice and order time limits, penalty exposure and payment concessions must be assessed under the correct provision. Do not accept a fraud penalty merely because a reconciliation difference exists.

Remedy 2: Seek release of credit blocked under Rule 86A

Blocking the electronic credit ledger is a restriction on using credit; it is not, by itself, a final determination of a tax demand. Under the presently operative Rule 86A framework, the Commissioner or an authorised officer not below Assistant Commissioner must have the prescribed reasons to believe that credit is fraudulent or ineligible and record reasons in writing.

Request the basis of the restriction, identify the blocked amount and submit evidence addressing each ground. Ask for release where the conditions no longer exist. The restriction ceases after one year from its imposition; expiry of blocking does not extinguish a separately lawful demand. An unlawful or continuing restriction may warrant judicial review, depending on the facts and available remedies.

Remedy 3: Appeal against a final order under Section 107

A taxpayer ordinarily has three months from communication of the decision or order to file the first appeal. The Appellate Authority can condone a further one month on sufficient cause. Preserve proof of communication and file FORM GST APL-01 with the order, facts, grounds and supporting documents in accordance with the applicable rules.

For an ordinary disputed tax demand, pay the admitted tax, interest, fine, fee and penalty in full, plus 10% of the remaining disputed tax, subject to the CGST statutory cap of Rs. 20 crore. Apply the corresponding SGST or IGST provisions where relevant. Penalty-only orders and specified special orders require separate checking.

Once the Section 107(6) payment requirements are met, Section 107(7) deems recovery of the balance stayed pending the appeal. Retain filing and payment proof. A representation to the officer is not a substitute for an appeal.

Grounds that may support an appeal

• The evidence establishes eligibility and was not properly considered.
• The authority applied the wrong financial-year rule or ignored a statutory exception.
• The calculation duplicates invoices, ignores reversals or includes credit never claimed.
• The proceedings breach limitation, hearing requirements or the grounds in the notice.
• Interest or penalty has been imposed without satisfying the applicable legal conditions.

Remedy 4: Rectification for an apparent error

Section 161 can address an error apparent from the record, such as an obvious arithmetic mistake. An affected person should bring the error to the authority's notice within three months of issue of the document. Rectification ordinarily cannot be made after six months; the statutory exception concerns clerical or arithmetic errors arising from accidental slips or omissions.

A contested factual or legal issue generally belongs in appeal rather than a request to correct an obvious error. Rectification does not automatically suspend recovery or stop the appeal clock. Protect the appeal deadline independently.

Can older or late ITC claims be protected?

Section 16(4) generally bars taking credit after 30 November following the relevant financial year, or furnishing the relevant annual return, whichever is earlier. Section 16(5) provides specified relief for invoices or debit notes relating to FY 2017-18 to FY 2020-21 where the Section 39 return was filed by 30 November 2021.

Section 16(6) addresses specified registration-cancellation cases subsequently revoked. Credit must not already have been time-barred on the cancellation order date; the provision compares the ordinary deadline with the specified returns filed within 30 days of revocation and allows the later route.

Circular 237/31/2024-GST explains implementation. The special rectification route under Notification 22/2024-Central Tax had a six-month application window from 8 October 2024; it is not an indefinitely open remedy. The retrospective amendments also carry a no-refund restriction for tax paid or credit reversed covered by Section 150 of the Finance (No. 2) Act, 2024. Do not assume relief automatically produces a refund.

Tribunal appeal and High Court remedies

An eligible order under Section 107 or 108 may be challenged before the GST Appellate Tribunal under Section 112. The statutory taxpayer period is three months from communication or the notified date, whichever is later, with limited condonation under the Act. Check the applicable notified filing window and bench procedure for the particular order.

For an ordinary tax dispute, the Tribunal stage generally requires an additional 10% of the disputed tax, subject to the CGST cap of Rs. 20 crore, besides admitted dues and the first-appeal deposit. The statutory stay follows compliance with Section 112(8). Penalty-only cases have separate requirements.

A writ petition under Article 226 may be considered for exceptional defects such as lack of jurisdiction or denial of natural justice. High Courts ordinarily expect the statutory appeal route to be used. A writ is not an automatic way to bypass pre-deposit requirements or revive a time-barred appeal; maintainability and interim relief depend on the facts.

Documents to organise before challenging denial

• The full notice or order, annexures, communication record and portal acknowledgements.
• Tax invoices, debit notes, purchase orders, contracts and supplier correspondence.
• GSTR-2A / GSTR-2B downloads, GSTR-3B filings and invoice-level reconciliation.
• E-way bills where applicable, transport records, goods receipt notes and stock records.
• Service deliverables, completion records, correspondence and proof of business use.
• Bank statements and supplier ledgers linking payments to invoices.
• Reversal and re-availment workings, earlier replies and hearing records.

Section 155 places the burden of proving eligibility on the person claiming ITC. A well-indexed evidence bundle should connect the supply, receipt, payment, reporting and credit claim, rather than simply contain a large number of invoices.

Frequently asked questions

Can I reclaim credit after a supplier corrects the default?

It depends on the reason for reversal and the applicable provision. Rules 37 and 37A contain re-availment mechanisms in specified circumstances. Confirm compliance and retain the evidence before reclaiming; avoid duplicate credit.

Does wrongly availed credit always attract interest?

Section 50(3) concerns credit wrongly availed and utilised. Examine actual utilisation and the Rule 88B calculation rather than assuming interest runs on every ledger entry. Other reversal provisions must be checked separately.

Should I wait for the supplier before filing an appeal?

No. Supplier cooperation can strengthen the evidence, but it does not extend the statutory appeal period. Preserve the deadline while pursuing the supplier's correction.

Does an invoice in GSTR-2B guarantee credit?

No. Receipt, business use and other statutory conditions remain relevant, and Section 17 restrictions may still apply.
