1. Short answer — retrospective cancellation does not automatically settle the buyer's ITC claim
But this is not a blanket protection. Section 16 contains substantive conditions, including receipt of goods/services and the statutory condition concerning payment of tax to the Government. The Supreme Court's July 2026 decision in Bhandari Scrap Traders v. Union of India affirmed the constitutional validity of Section 16(2)(c). A buyer should therefore never build a defence merely around the statement that “the supplier was active on the invoice date.”
2. Why this problem is so common
A supplier may appear valid when the buyer purchases goods and later become non-compliant. The GST portal can subsequently show cancellation from a past date. This creates a very different situation from a transaction where the supplier was already cancelled or never genuinely existed.
Situation A — later retrospective cancellation
Supplier was shown as registered when the invoice was issued. Months later, registration is cancelled with an effective date covering the earlier period.
Situation B — supplier was already cancelled
Invoice is issued after the effective cancellation date. This is substantially riskier and requires a different analysis.
Situation C — invoice in GSTR-2B
Supplier reported the invoice and it appeared in the buyer's GSTR-2B, but later compliance problems arose.
Situation D — suspicious or non-existent supplier
Registration may have been cancelled because the entity was found non-existent or fraudulent. Genuine transaction evidence becomes critical.
3. What Section 16 means for the buyer
Section 16 is not a single-condition provision. The buyer should test the complete chain. The exact statutory text and amendments applicable to the relevant tax period must always be checked before taking a final position.
| Test | Practical question | Evidence |
|---|---|---|
| Business use | Was the inward supply used/intended for business? | PO, GRN, project/site records, service records |
| Tax document | Do we hold a valid invoice/debit note? | Tax invoice, debit note, contract/work order |
| Supplier status | Was the supplier shown as registered for the relevant transaction? | Portal verification saved at the time where available |
| Receipt | Did goods/services actually reach the recipient? | GRN, LR, EWB, gate entry, weighbridge, service completion |
| Reporting trail | Was the document reported in the supplier-side system / GSTR-2B where applicable? | GSTR-2B, IMS records, supplier confirmation |
| Tax payment | Was tax charged on the supply actually paid to Government as required? | Supplier return/tax payment evidence where available; department records |
| Recipient return | Was the recipient's return furnished? | GSTR-3B filing record |
4. Five-minute decision tree
Was supplier registered on the relevant date?
When did cancellation become effective?
Were goods/services actually received?
Can the transaction be independently proved?
What can be established about supplier tax payment?
- Supplier registered at transaction time.
- Goods/services actually received.
- Invoice, EWB/GRN/service evidence exists.
- Payment through banking channels.
- Invoice reported and reflected in GSTR-2B where applicable.
- No allegation of collusion or bogus transaction.
- Supplier was non-existent.
- Invoice issued after effective cancellation.
- No proof of receipt.
- Cash payment with weak documentation.
- Circular trading indicators.
- Department establishes that the transaction itself is fictitious.
5. Important case laws — what they actually help with
The Court considered retrospective supplier cancellation where the purchaser had invoices, transportation documents and bank-payment evidence. It held that the authorities could not reject the ITC claim merely by relying on retrospective cancellation without considering the supporting documents, and remanded the matter for a reasoned decision.
Practical lesson: retrospective cancellation is not a substitute for examining whether the underlying purchase was genuine.
The Court expressed the prima facie view that where the supplier was registered when the transaction took place, retrospective cancellation subsequently should not by itself deprive a bona fide recipient of ITC, particularly where the department did not dispute that the supplier had deposited the tax collected. The order was an interim-stage decision.
Practical lesson: registration at transaction time and actual tax payment are both relevant facts.
The Court observed that retrospective cancellation cannot be mechanical and should be based on objective criteria. It also noted the department's own position that retrospective cancellation can affect customers' ITC, making the retrospective date a matter requiring proper consideration.
Practical lesson: the cancellation order and its reasoning can be important evidence.
The Court dealt with ITC from retrospectively cancelled suppliers and noted the importance of establishing that supplies were actually obtained from suppliers registered at the relevant time and had discharged their corresponding tax liability. The petitioner was directed to respond with supporting factual material.
Practical lesson: buyer evidence and supplier tax compliance should be addressed together.
The Court set aside orders where ITC had been rejected solely because the supplier's registration was cancelled retrospectively. It directed reconsideration after examining invoices, e-way bills, lorry receipts and other evidence establishing genuineness of supply.
Practical lesson: put transaction evidence on record instead of arguing only from registration status.
The Supreme Court affirmed the Gujarat High Court's view upholding the constitutional validity of Section 16(2)(c), concerning payment of tax charged on the supply to Government. This is a major caution against presenting retrospective-cancellation case law as an absolute right to ITC.
Practical lesson: address the statutory tax-payment condition separately.
6. The buyer's ITC defence file — keep this evidence together
Your strongest defence is not a single screenshot. Build an evidence chain that proves the transaction from order to payment.
| Evidence | Why it matters | What to preserve |
|---|---|---|
| Supplier GST registration check | Shows how supplier appeared at the time. | Saved portal verification / vendor master record |
| Tax invoice | Establishes supplier, recipient, tax and invoice particulars. | Original invoice + accounting entry |
| PO / work order | Shows commercial basis. | Approved PO, contract, rate confirmation |
| GRN / inward record | Supports actual receipt. | GRN, site receipt, gate entry, weighment |
| E-way bill | Supports movement where applicable. | EWB, Part-B/vehicle details, delivery evidence |
| Lorry receipt | Independent transport evidence. | LR/consignment note and transporter details |
| Bank statement | Supports payment. | Bank statement + payment voucher + UTR |
| GSTR-2B / IMS | Shows system-side reporting trail. | Relevant 2B and IMS history where applicable |
| Stock / consumption | Supports actual business use. | Stock register, issue slip, project consumption |
| Supplier correspondence | Explains amendments or filing delays. | Email/confirmation requesting compliance |
7. 25 practical situations — what should the accountant do?
| Situation | Practical view | Immediate action |
|---|---|---|
| 1. Registered on invoice date; later cancelled retrospectively | Cancellation alone should not end the analysis. | Compile complete transaction evidence. |
| 2. Cancelled before invoice date | High-risk; eligibility requires detailed review. | Do not assume ITC is safe. |
| 3. Invoice appeared in GSTR-2B, later cancelled | 2B supports reporting trail but does not replace Section 16. | Preserve 2B and transaction evidence. |
| 4. Supplier stopped filing GSTR-3B | Tax-payment condition becomes important. | Obtain supplier status and respond carefully. |
| 5. Supplier did not pay tax | Section 16(2)(c) risk is substantive. | Do not use cancellation case law as the only defence. |
| 6. Goods received with EWB + GRN | Strong movement/receipt evidence. | Link EWB to invoice and GRN. |
| 7. Goods received but required EWB unavailable | Evidence gap; risk increases. | Collect LR, gate entry, transporter and stock records. |
| 8. Services actually received | No physical movement evidence may exist. | Use agreement, deliverables, emails and acceptance. |
| 9. Payment by bank | Supports commercial genuineness. | Map invoice → payment → ledger. |
| 10. Cash payment | Weaker audit trail. | Strengthen receipt and delivery evidence. |
| 11. Supplier shown active on portal | Useful contemporaneous due-diligence evidence. | Preserve available verification record. |
| 12. Cancellation for non-filing | Cancellation reason matters. | Obtain cancellation order/reason. |
| 13. Cancellation for non-existent business | Materially higher risk. | Prove supplier identity, delivery and payment independently. |
| 14. Invoice not in GSTR-2B | Separate reporting/reconciliation issue. | Check supplier filing, GSTIN, invoice and amendments. |
| 15. Wrong GSTIN in invoice | Fundamental document/reporting issue. | Use lawful correction/reporting route and document facts. |
| 16. Credit note later issued | ITC may need adjustment. | Reconcile credit note with original invoice. |
| 17. Invoice amended by supplier | 2B may show amendment impact. | Track original + amendment + ITC effect. |
| 18. Supplier says tax paid but no direct proof | Buyer may lack direct access to supplier ledger. | Keep supplier confirmations and request compliance evidence. |
| 19. Department relies only on cancellation | Transaction-level examination is still important. | Submit evidence and request reasoned finding. |
| 20. Department alleges bogus purchase | Issue is wider than cancellation. | Address identity, movement, receipt, payment and consumption. |
| 21. Multiple invoices from same supplier | Pattern analysis matters. | Prepare invoice-wise evidence schedule. |
| 22. Related-party/common directors | Commercial substance needs stronger support. | Document pricing, contract, delivery and business purpose. |
| 23. High-value site purchases | Physical receipt evidence is especially important. | Keep site GRN, gate entry, vehicle and consumption records. |
| 24. ITC already reversed after notice | Analyse whether re-availment is legally possible later. | Track reason, return table and conditions. |
| 25. SCN lacks invoice-wise findings | Still respond factually; do not ignore. | Prepare invoice-wise reconciliation and request proper findings. |
8. You received an ITC reversal notice — what should you do first?
Step 1 — Freeze the facts
Download notice, annexures, disputed invoice list and supplier GSTIN list.
Step 2 — Build invoice population
Create one row per invoice with date, tax, supplier status, 2B status and payment date.
Step 3 — Classify the reason
Separate retrospective cancellation, non-filing, non-payment, missing 2B, fake supplier and document deficiency.
Step 4 — Build evidence score
Mark invoice, receipt, transport, bank payment, 2B and consumption/service evidence.

9. How to structure a professional reply to the department
- Start with the issue. State exact ITC amount and invoice population.
- Explain supplier status. Give invoice date, status at transaction time and later cancellation effective date.
- Establish actual supply. Attach/index invoice, PO, GRN, EWB, LR, gate entry, service completion or equivalent evidence.
- Establish payment. Provide bank statement/UTR and ledger mapping.
- Address GSTR-2B. Show whether each invoice appeared and whether amendments/credit notes affected it.
- Address Section 16. Respond separately to receipt, documentation, reporting and tax-payment conditions applicable to the period.
- Use case law factually. Explain why the cited case resembles your facts.
- Request invoice-wise findings. Ask which statutory condition is considered unmet for each invoice.
10. Claim, defer, reverse or defend? Practical matrix
| Facts | Suggested treatment | Reason |
|---|---|---|
| Supplier active; genuine receipt; documents complete; no adverse evidence | Claim / defend if questioned | Strong factual record. |
| Supplier later retrospectively cancelled; evidence complete | Do not reverse solely because of cancellation; defend with evidence | Case law supports transaction-level examination. |
| Supplier already cancelled on invoice date | High-risk; obtain professional review | Supplier registration condition and document validity become critical. |
| Supplier did not pay tax | Analyse Section 16(2)(c) separately | Supreme Court 2026 upheld validity of the condition. |
| Goods/services not actually received | ITC should not be claimed / should be corrected as required | Receipt is a statutory condition. |
| Supplier appears non-existent and transaction cannot be substantiated | Very high risk | Issue is no longer merely retrospective cancellation. |
| Invoice missing from 2B but genuine purchase exists | Investigate reporting and eligibility before claim | 2B mismatch is a separate reconciliation problem. |
11. Prevent the problem — vendor GST controls
Verify GSTIN, legal name, bank details, address and business profile. Keep approval evidence.
Check GSTIN, invoice number/date, tax rates, place of supply and eligibility.
Reconcile purchase register to GSTR-2B and follow up missing invoices.
Track unpaid invoices and the 180-day rule separately from supplier tax compliance.
Require stronger documentation for large purchases, site supplies and unusual transactions.
Store invoice, GRN, EWB, LR, payment and 2B evidence in one invoice-linked folder.
12. Common mistakes buyers make
- Assuming GSTR-2B appearance guarantees ITC eligibility.
- Assuming retrospective cancellation automatically destroys ITC.
- Using one High Court judgment as a universal rule across all facts and jurisdictions.
- Ignoring Section 16(2)(c) after the Supreme Court's 2026 ruling.
- Failing to preserve supplier registration status evidence at onboarding/transaction.
- Keeping only invoices and not GRNs, EWBs, LR or service-completion records.
- Not reconciling amendments and credit notes.
- Responding with a general explanation instead of an invoice-wise schedule.
- Calling every supplier cancellation case a fake-invoice case.
- Reversing ITC mechanically without understanding the notice and legal basis.

14. FAQs — supplier cancellation and buyer ITC
If my supplier's GST registration is cancelled retrospectively, do I automatically lose ITC?
No. Retrospective cancellation alone should not be treated as the end of the enquiry. Courts have required examination of the actual transaction and evidence. The buyer must still satisfy applicable Section 16 conditions.
What if the supplier was active on the invoice date but later stopped filing returns?
That is a separate compliance issue. Preserve evidence of the genuine transaction and separately address the statutory tax-payment condition.
Is GSTR-2B enough to prove my ITC?
No. GSTR-2B is an important reconciliation statement, but ITC eligibility remains subject to statutory conditions.
What if the department says the supplier was fake?
Then the dispute is broader than retrospective cancellation. Prove supplier identity, actual receipt, transport, payment, business use and commercial substance.
Does bank payment prove ITC eligibility?
No. Bank payment is useful evidence of commercial genuineness, but it does not replace other statutory conditions.
Does an e-way bill prove the purchase?
An e-way bill can support movement evidence, but it should be read with invoice, GRN, LR, delivery and accounting records.
What did the Supreme Court decide in Bhandari Scrap Traders?
On 24 July 2026, the Supreme Court affirmed the Gujarat High Court judgment upholding the constitutional validity of Section 16(2)(c). The ruling makes it important to address the supplier-tax-payment condition separately.
Can I rely on Gargo Traders everywhere?
Use it as persuasive case law and compare the facts. A High Court decision is not automatically a universal rule for every jurisdiction and factual situation.
What is the strongest evidence for goods?
A combined trail: PO, invoice, EWB, LR, GRN/gate entry, stock or project consumption and bank payment.
What is the strongest evidence for services?
Agreement/work order, invoice, service deliverables, timesheets or milestones, emails, acceptance/completion records and payment trail.
Should I immediately reverse all disputed ITC on receiving a notice?
Do not make a mechanical decision. First classify the notice, verify period and legal basis, quantify disputed invoices and obtain appropriate professional advice.
Can the department reject ITC without examining my documents?
Case law has emphasised proper examination of relevant evidence in appropriate fact situations. Place the evidence on record and request invoice-wise, reasoned findings.
Case-law reference note
This guide has been prepared using the statutory framework under Section 16 of the CGST Act and recent judicial decisions relevant to supplier registration cancellation and ITC. Key decisions discussed include M/s Gargo Traders (Calcutta High Court, 12 June 2023), M/s Aditya Craft & Papers Pvt. Ltd. (Orissa High Court, 5 May 2025), S R Enterprises (Delhi High Court, 3 February 2025), Pankaj Mittal (Delhi High Court, 4 February 2025), Tvl. Fathima Traders (Madras High Court, 12 June 2026), and Bhandari Scrap Traders v. Union of India (Supreme Court, 24 July 2026).
Case law is included for practical understanding and is not a substitute for reading the full judgment. The outcome of an ITC dispute depends on the relevant tax period, statutory amendments, jurisdiction and evidence available in the particular case.
Final takeaway — defend the transaction, not just the registration
When a supplier's GST registration is cancelled retrospectively, the professional question is: what was the status when the transaction occurred, did the supply genuinely happen, and can the buyer prove every relevant statutory condition?
Check status and cancellation effective date
Prove genuine supply and receipt
Link books, 2B and supplier reporting
Address Section 16(2)(c) separately
Prepare invoice-wise defence file
If another accountant can open your ITC file years later and reproduce the purchase from PO → invoice → receipt → EWB/LR → accounting → 2B → payment → return, you have built a much stronger compliance record than an invoice-only file.
