Your next step is to identify the exact reason in the notice or order, test each statutory condition in section 16 of the Central Goods and Services Tax (CGST) Act, and submit transaction-level evidence. Missing GSTR-2A/2B data, non-payment of tax by the supplier, failure to receive the goods or services, defective documents, a 180-day payment issue, and a time-limit dispute are separate questions with different evidence and remedies.
Start with the notice or order, not the supplier’s explanation
Obtain the complete document, including annexures and the method and date of service. Record the tax period, amount of ITC, legal provisions cited, factual allegations, reply channel, hearing details and any appeal instructions. A demand based only on invoice non-reflection requires a different response from one alleging that no goods were received or that the supplier did not pay tax to the government.

Do not assume that a communication about a mismatch is a final demand. A show-cause notice gives you an opportunity to present evidence; an adjudication order creates a different procedural position. Once an order has been issued, have a GST practitioner or tax lawyer check the current appeal provision, forum, limitation period, pre-deposit and filing method against that specific document and jurisdiction. The applicable deadline cannot safely be stated without those facts.

Map the allegation to the relevant section 16 condition
Section 16 of the CGST Act sets the conditions for taking ITC. The operative text and amendments should be checked before you rely on any wording. The common grounds below must remain distinct.
#1 Best Overall
| Alleged problem | Question the authority is asking | Evidence to address it |
|---|---|---|
| Invoice or debit note not furnished by the supplier | Did the supplier report the document details in the prescribed manner so they were communicated to the recipient? | Tax invoice data, GSTR-2A/2B snapshots for the relevant period, purchase register, supplier filing or correction correspondence and reconciliation. |
| Supplier allegedly did not pay tax to the government | Was the tax charged on the supply actually paid, subject to the Act’s rules? | Proof of a genuine taxable supply, supplier communications and all transaction records. Do not state that you verified payment unless you actually did; a matching screen does not independently prove every supplier payment fact. |
| Goods or services not received | Can you establish receipt or completion of the supply? | Delivery acknowledgement, e-way bill and transport records, stock or production entries, service contract, work papers, deliverables, acceptance records and payment trail. |
| Recipient did not pay the supplier within 180 days | Was the value plus tax paid within the statutory period? | Bank statements, payment advice, ledger and settlement records. If the condition was triggered, the corresponding credit is added to output-tax liability with interest in the prescribed manner and becomes available again when payment is made. |
| Defective or missing prescribed document | Do you possess a valid tax invoice, debit note or other prescribed document? | Original document, corrected document where law permits, purchase order and contract showing the parties, supply and tax details. |
| Section 16(4) time limit | Was the credit taken within the applicable statutory cut-off? | Return filing dates, invoice dates, relevant annual-return dates and the computation used in the notice. |
You also must have furnished the recipient return under section 39. A response should address every ground actually stated; do not let a strong receipt file obscure a separate time-limit or document failure.
Build an invoice-by-invoice evidence file
Create one indexed folder or PDF set for each disputed invoice. A spreadsheet should cross-reference the invoice number, date, supplier GSTIN, taxable value, tax amount, purchase-register entry, GSTR-2A/2B status, return in which credit was claimed, payment date and the page number of each attachment. Preserve contemporaneous records in their original form and explain any later correction.
Core records for every supply
- Tax invoice, debit note or other prescribed document.
- Purchase order, contract, quotation and agreed delivery or service terms.
- Accounting entry, purchase register, inventory or expense ledger and tax calculation.
- Bank statement, payment advice, set-off documentation or other proof of payment to the supplier.
- Recipient return extracts and dated GSTR-2A/2B reconciliation for the relevant period.
- Emails, letters or messages concerning delivery, quality, corrections, filing or tax records.
Additional proof for goods
- E-way bills, lorry receipts, consignment notes, weighbridge slips and transporter invoices where relevant.
- Goods-received note, warehouse acknowledgement, gate register or delivery challan.
- Stock movement, production consumption or subsequent sales records that are consistent with the quantity received.
- Evidence identifying the vehicle, driver or carrier when transport is disputed.
Additional proof for services
- Statement of work, engagement letter and milestones.
- Timesheets, work papers, reports, designs, tickets, meeting records or other deliverables.
- Acceptance email, completion certificate or internal approval showing the service was used.
- Invoices linked to the contract and payment schedule.
Never create or backdate a document to fill a gap. If a record is unavailable, say so and provide independent evidence that addresses the same fact.

Reconcile GSTR-2A and GSTR-2B without treating a mismatch as the whole case
Download or preserve the relevant period’s GSTR-2A and GSTR-2B and compare them with your books and filed returns. Check invoice number, date, supplier GSTIN, taxable value, tax rate, tax amount, credit-note adjustments and amendments. A document can appear in a later period, be amended, or be omitted because the supplier did not furnish the required details.
Absence from GSTR-2A alone is not conclusive on every fact pattern. In WP(C) No. 29769 of 2023 (2023:KER:55318), the Kerala High Court held, on the facts before it, that denial solely because tax was not reflected in GSTR-2A was not sustainable and remanded the matter for evidence review. That fact-specific state ruling is not a nationwide guarantee that an invoice always earns credit or that section 16 conditions can be ignored. Use it to argue for a proper examination of your evidence, not as a substitute for proving receipt, documents, filing and the other statutory requirements.
Ask the supplier to correct the record, but do not wait for that response
Write to the supplier using a traceable channel. Identify each invoice and request confirmation of the relevant return filing, correction or amendment, and any available evidence that tax was reported and paid. Give a reasonable response date and retain your email, letter, delivery proof and the reply (or non-response).
A supplier’s promise to correct a return is not proof that the correction occurred, and it does not extend your notice deadline. Submit your own reply on time, identify the supplier contact effort, and update the authority if a correction later appears. Do not claim that you independently verified the supplier’s tax payment when you only requested confirmation.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minutePrepare the response in the order an officer can verify
- State the disputed amount and period. Provide an invoice schedule with totals that reconcile to the notice.
- Answer each allegation separately. Use headings matching the notice: invoice reporting, receipt, document validity, tax-payment condition, 180-day payment and time limit.
- Explain the transaction flow. For goods, describe order, dispatch, transport, receipt and use. For services, describe engagement, performance, acceptance and use.
- Point to indexed evidence. Cite attachment numbers and page ranges rather than sending an unstructured document dump.
- Address discrepancies candidly. Explain invoice amendments, later-period reflection, quantity differences, credit notes or delayed payment with supporting records.
- Request the appropriate outcome. Ask that the proposed reversal be dropped where conditions are met, or that the authority examine the complete evidence and give a reasoned finding on each invoice.
- Keep proof of filing. Save the acknowledgement, uploaded files, email headers and hearing notes.
Use accurate facts only. An invoice and a cheque or bank transfer prove payment, but they may not by themselves prove actual movement or receipt of goods.
What the Ecom Gill decision does—and does not—decide
In The State of Karnataka v. M/s Ecom Gill Coffee Trading Private Limited, decided on 13 March 2023, the Supreme Court interpreted section 70 of the Karnataka Value Added Tax Act, 2003. In that state-VAT dispute, it held that invoices and cheque payments alone did not discharge the purchasing dealer’s burden; the Court referred to seller identity, vehicle and delivery particulars, freight, delivery acknowledgement, invoices, payment details and actual movement of goods.

This is an evidentiary illustration, not a direct interpretation of section 16 of the CGST Act. Cite the statutory provisions and your own transaction evidence first, and explain the legal distinction if the authority relies on the case.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Do not use receipt circulars to answer a tax-payment dispute
CBIC Circular 241/35/2024-GST, dated 31 December 2024, concerns deemed receipt under section 16(2)(b), including qualifying Ex-Works arrangements in which goods are handed to a transporter at the supplier’s premises under the contract. It may help where the dispute is whether the recipient received the goods. It is not a general cure for a dispute under section 16(2)(c) about whether the supplier paid the tax to the government.
CBIC Circular 238/32/2024-GST, dated 8 October 2024, provides special relief connected with retrospectively inserted sections 16(5) and 16(6) in certain cases where denial was solely because of the section 16(4) time limit. The relief calculation does not convert a supplier-compliance failure into eligible credit. Confirm that the only denial ground is the time limit before relying on it, and check the current circular and statutory text.

If an order has already reversed the credit
Separate the merits from procedure. Read the order’s findings invoice by invoice and note whether it confirms tax, interest, penalty or any other amount. Check the service date and the appeal instructions against current central and state rules. A practitioner should calculate the limitation period, any mandatory pre-deposit and the documents required by the specified appellate forum.
Preserve the complete adjudication record, your original reply, hearing submissions, acknowledgements and evidence index. If the amount is material, the order alleges fraud or suppression, evidence is disputed, or a deadline is close, obtain qualified advice immediately rather than filing an unsupported template.
Common mistakes that weaken an ITC defence
- Arguing only that the invoice appears in the books while ignoring receipt or the supplier-furnished-details condition.
- Treating GSTR-2B as conclusive proof that the supplier paid tax to the government.
- Using Circular 241/35/2024-GST to answer a section 16(2)(c) tax-payment allegation.
- Invoking the Kerala High Court decision as an automatic, all-India entitlement.
- Submitting invoices and payment proofs without transport, stock or service-completion evidence when receipt is challenged.
- Waiting for the supplier to amend a return until the notice deadline expires.
- Using a generic appeal deadline without checking the actual order, service date and jurisdiction.
- Providing reconstructed or backdated records instead of explaining an evidentiary gap.
A practical decision tree
- Only GSTR-2A/2B reflection is disputed: reconcile the invoice, show receipt and payment, document supplier contact, and request an evidence-based review.
- Receipt is disputed: prioritize delivery, transport, stock or service-performance records; Circular 241/35/2024-GST may be relevant only to its qualifying deemed-receipt facts.
- Supplier tax payment is disputed: address the statutory condition directly, provide genuine-supply evidence and avoid claiming proof you do not possess.
- Payment to supplier exceeded 180 days: calculate the period invoice by invoice, account for the prescribed reversal with interest if triggered, and document subsequent payment for re-availment.
- Section 16(4) time limit is the sole ground: verify the dates and examine whether the specific statutory or circular relief applies.
- Fraud, sham transaction or non-existent supplier is alleged: seek specialist advice immediately and preserve all original records.
When professional help is warranted
Get a GST practitioner or tax lawyer promptly when an order has issued, the exposure is substantial, the notice alleges fraud or collusion, the supplier cannot be traced, goods or services are difficult to evidence, or the limitation period is near. Provide the adviser with the notice or order, service proof, invoice reconciliation, evidence index, supplier correspondence and prior submissions. The adviser can then assess the correct forum and grounds instead of relying on a generic ITC-mismatch response.
