Rule 86A explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
One day the credit you were about to use to pay tax shows as blocked. Rule 86A lets a senior officer stop you from using credit in the electronic credit ledger when he has reason to believe it was fraudulently availed or is ineligible. The power is strong, but the rule puts limits on who can use it, for what, and for how long.
Under Rule 86A, the Commissioner or an officer authorised by him, not below the rank of Assistant Commissioner, may, for reasons recorded in writing, refuse to allow debit of an amount equal to the suspect credit, both for paying liability under section 49 and for claiming refund. It covers five grounds. The officer can lift the block when satisfied, and under Rule 86A(3) the restriction ceases after one year from the date it was imposed.
The five grounds
The officer must have "reasons to believe" that credit in the ledger has been fraudulently availed or is ineligible, in one of these ways:
| Clause | Ground |
|---|---|
| (a)(i) | Credit taken on a Rule 36 document issued by a registered person found non-existent or not conducting business from the place of registration |
| (a)(ii) | Credit taken on a document without receipt of goods or services or both |
| (b) | Credit taken on a document where the tax charged has not been paid to the Government |
| (c) | The person availing the credit is himself found non-existent or not conducting business from the registered place |
| (d) | The person availing the credit has no tax invoice, debit note or other Rule 36 document |
The reasons have to be recorded in writing before the block is placed. If you are already facing one, a GST notices and litigation review of the order is the sensible first step. Clause (b) is the one that most often overlaps with a supplier who has not paid over tax. If this is your situation, read it with Rule 37A reversal when the supplier does not file GSTR-3B, which is a separate statutory route with its own dates.
What gets blocked
The block is on debit of "an amount equivalent to such credit". It is not a freeze of the whole ledger. The Background Material, summarising the departmental instruction, says the restriction should be limited to the suspected amount. The block stops you from using that amount in two ways: to discharge any liability under section 49, and to claim refund of unutilised credit.
Illustration with round figures. Your ledger shows Rs. 8,00,000 of ITC. An officer blocks Rs. 3,00,000 on 12 February 2026. Rs. 5,00,000 remains usable. The Rs. 3,00,000 cannot be used against output tax or claimed as refund. The restriction ceases once one year from 12 February 2026 has expired, unless the officer has lifted it earlier.
Who can block, and how much authority they have
Rule 86A names the Commissioner or an officer authorised by him, not below Assistant Commissioner. The Background Material reports Instruction No. CBEC-20/16/05/2021-GST dated 02.11.2021, which sets approval levels by monetary limit:
| Officer | Monetary limit |
|---|---|
| Deputy or Assistant Commissioner | Up to Rs. 1 crore |
| Additional or Joint Commissioner | Above Rs. 1 crore up to Rs. 5 crores |
| Principal Commissioner or Commissioner | Above Rs. 5 crores |
The instruction, as summarised there, also says that grounds must rest on evidence amounting to "reasons to believe", that the procedure requires reasons in writing, and that notification is through the portal. It says reviews can unblock credit on evidence, with automatic expiry after one year. The material does not reproduce the instruction in full, so read the instruction itself where the point is contested.
Lifting the block and the one-year lapse
Two provisions help you:
- Rule 86A(2). The Commissioner, or the officer authorised under sub-rule (1), may allow the debit once satisfied that the conditions for disallowance no longer exist.
- Rule 86A(3). The restriction ceases to have effect after the expiry of one year from the date of imposing it.
So the practical task is to give the officer the proof that removes the ground. The rule text does not prescribe a separate application form or a formal appeal for a blocking order. Whether and how a blocking order can be challenged is a legal question and depends on the facts. The text gives you the lift under 86A(2) and the lapse under 86A(3).
What proof fits which ground:
| Ground | Evidence that usually answers it |
|---|---|
| Supplier non-existent | Proof that the supplier was active and registered at the time, with transaction records |
| No receipt of supply | Transport documents, e-way bills, goods receipt notes, service delivery records |
| Tax not paid by the supplier | Supplier's return and payment details, and your own payment trail |
| Your own premises not found | Lease or ownership papers, utility bills, operational records |
| No invoice or document | The original tax invoice, debit note or other Rule 36 document |
This table is our practical summary of how each ground can be met. It is not a list from the rule. The material itself, discussing credit on goods received, stresses that a tax invoice alone is never enough and that supporting documents for movement and delivery must be kept. See Rule 36 and the documents that support a credit claim.
How Rule 86A differs from Rule 86B
Rule 86A and Rule 86B both restrict use of the credit ledger, but they are unrelated.
| Point | Rule 86A | Rule 86B |
|---|---|---|
| Trigger | Officer's reason to believe credit is fraudulent or ineligible | Taxable supply above Rs. 50 lakh in a month |
| Who acts | Commissioner or authorised officer | Applies automatically |
| Effect | Blocks an amount equal to the suspect credit | Credit cannot discharge more than 99 percent of output tax |
| Duration | Ceases after one year | Continues while the conditions are met |
Rule 86B has its own exemptions, such as income tax paid above Rs. 1 lakh in each of the last two years, which are covered in the series on Rule 86B and the one percent cash rule.
What to do in the first week
- Note the amount, the date and the ground stated.
- Find out which return periods and invoices the blocked credit comes from.
- Collect the evidence that matches the stated ground.
- Write to the officer who blocked, asking for the block to be lifted under Rule 86A(2) and attach the evidence.
- Keep paying liability in cash where needed. Do not assume the matter will resolve before the return is due.
A block also tells you which invoices the department is looking at, so a documented reply early on is worth the effort.
