How Rule 86A of CGST Rules Blocks Input Tax Credit
Last updated: 26 October 2026
Quick Answer: Rule 86A of CGST Rules, 2017 lets the Commissioner or an authorised officer block credit-ledger debits for up to one year. Written reasons citing one of five fraud or ineligibility grounds come first; the block covers payments and refunds up to the suspect credit. HSAG Consulting's indirect tax team advises companies on credit blocks and represents them in GST assessments.
The Rule 86A of CGST Rules notification is Notification No. 75/2019-CT dated 26.12.2019, which inserted the rule into the Central Goods and Services Tax Rules, 2017. It works as a preventive freeze on the electronic credit ledger, applied before any demand under sections 73, 74 or 74A of the Central Goods and Services Tax Act, 2017 is finalised.
However, the legal validity of Rule 86A has frequently been challenged in various High Courts with a view that Rule 86A is a subordinate legislation creating a harsh, restrictive power to freeze a taxpayer's asset/credit ledger without a substantive empowering section in the parent Act itself.
What Powers Does Rule 86A Give the Department?
The Commissioner, or an officer authorised by him not below the rank of Assistant Commissioner, may invoke Rule 86A. The officer must have “reasons to believe” that credit of input tax available in the electronic credit ledger has been fraudulently availed or is ineligible. The rule permits five grounds, set out in the rule text on the CBIC portal.
| Clause | Ground for blocking the credit |
|---|---|
| (a)(i) | Credit availed on invoices, debit notes or other rule 36 documents issued by a supplier found non-existent or not conducting business from any registered place |
| (a)(ii) | Credit availed on such documents without receipt of the goods or services or both |
| (b) | Credit availed on such documents for a supply whose tax has not been paid to the Government |
| (c) | The person availing the credit found non-existent or not conducting business from any registered place |
| (d) | The person availing the credit not in possession of the tax invoice, debit note or other document prescribed under rule 36 |
Written reasons must be recorded first. Only then may the officer disallow debit of an amount equivalent to the suspect credit, both for discharge of any liability under section 49 of the CGST Act, 2017 and for claim of any refund of an unutilised amount. A block can therefore hold up a refund of unutilised credit, which is why the note on refund management for better cash flow treats delayed refunds as working capital held back.
What Safeguards Do the CBIC Guidelines Impose?
The CBIC GST Policy Wing issued guidelines on 2 November 2021, after High Courts stressed the need for guidelines on invoking the rule. The CBIC guidelines on Rule 86A state that the power must not be exercised in a mechanical manner and call for careful examination of all the facts of the case.
- Objective basis: the reasons must rest on material evidence, an objective determination based on intelligent care and evaluation, not subjective suspicion.
- Written reasons first: the officer must record reasons in writing on file before disallowing the debit.
- Amount cap: the amount blocked must not exceed the input tax credit believed fraudulently availed or ineligible.
- Portal intimation: the registered person is informed of the action on the portal, with details of the officer who disallowed the debit.
- Monetary limits: the guidelines advise authorising officers by amount. Up to ₹1 crore goes to a Deputy or Assistant Commissioner, above ₹1 crore up to ₹5 crore to an Additional or Joint Commissioner, and above ₹5 crore to a Principal Commissioner or Commissioner.
What Must the Officer Weigh Before Blocking Credit?
Before blocking credit, the officer must form an opinion only after proper application of mind. Paragraph 3.1.3 of the CBIC guidelines names three factors: the nature of the suspect credit and whether a Rule 86A ground covers it, the amount involved, and whether a block is necessary to protect the revenue.
Paragraph 3.4.3 adds that a block bears on the working capital of the registered person, and asks that the investigation and adjudication be completed at the earliest, well within the one-year restriction.
How Does a Rule 86A Block Appear on the GST Portal?
A Rule 86A block appears in the Electronic Credit Ledger on the GST portal. The portal FAQs on that ledger state that an email and an SMS reach the taxpayer when credit is blocked or unblocked, and that a debit entry is posted for the blocked amount.
Under Services, Ledgers, Electronic Credit Ledger, the GST portal user manual shows a Blocked Credit Balance by date range. An Attachment link opens any document the tax official uploaded, and the Description link names the official who blocked or unblocked the amount.
According to the same manual, a block larger than the balance turns the ledger negative, later credits are first set off against that figure, and negative amounts cannot pay any liability. The Punjab and Haryana High Court has set such negative entries aside, but the High Courts are divided on the point, as explained below.
GSTN's compilation of new portal functionalities for April 2023 to March 2024 records that blocked credit is auto unblocked after one year for active taxpayers only. Taxpayers with other statuses, such as cancelled or suspended, are excluded.
How Long Does a Block Under Rule 86A of CGST Rules Last?
A restriction under sub-rule (3) of Rule 86A ceases to have effect after the expiry of one year from the date it was imposed. Whatever the outcome of the underlying investigation, the block is therefore temporary.
Earlier lifting is also possible. Under sub-rule (2), the Commissioner or the authorised officer may allow the debit again once satisfied that the conditions for disallowing it no longer exist. The guidelines say the officer may examine the matter afresh, either on his own or on the taxpayer's submissions with material evidence, and may allow the credit up to the extent of eligibility, partially or fully.
Can the Ledger Be Blocked Beyond the Available Balance?
Various High Courts are divided and have their own view. The Gujarat, Delhi, Telangana, Bombay, and Punjab and Haryana High Courts have held that Rule 86A permits blocking only of the credit actually available in the electronic credit ledger. Against that view, the Calcutta, Allahabad and Andhra Pradesh High Courts have allowed blocking beyond it. The GST portal still lets officials block more than the balance: its Electronic Credit Ledger FAQs say a tax official can block credit in excess of the amount available.
In M/s H.S Enterprises v. State of Punjab and others (CWP No. 34639 of 2025, decided 20 November 2025), the Punjab and Haryana High Court set aside entries that blocked credit in negative. Without credit available in the ledger, it held, there cannot be negative blocking.
Against a Delhi High Court decision to the same effect, the Supreme Court dismissed the special leave petition against Kings Security Guard Services on 16 May 2025 (Diary No. 17900/2025). The H.S Enterprises judgment also quotes the Gujarat High Court in Samay Alloys India Pvt. Ltd., which called the power extremely harsh and noted that it is invoked at a stage anterior to the finalisation of an assessment or the raising of a demand.
What Remedies Does a Company Have Against a Block?
A company facing action under Rule 86A of CGST Rules, 2017 has three practical routes, which can run in parallel, and one pending change to watch.
- Make a representation: file submissions with material evidence showing the credit is eligible. Under paragraph 3.4.1 of the guidelines, the officer may examine the matter afresh on such submissions, and must record on file, in writing, the reasons for allowing the debit before allowing it.
- Track the one-year limit: confirm the date the restriction was imposed, because it lapses by statute after one year even if no order is passed.
- Approach the High Court: a writ petition lies where the block exceeds the credit available in the ledger, in the High Courts that follow this view, as the H.S Enterprises case shows.
- Watch the pending amendment: on 8 October 2026 the GST Council recommended amending rule 86A so that a taxpayer can file an objection against a block and get a personal hearing before the officer decides that objection. This is a recommendation, not yet law; rule 86A applies as written until the amendment is notified.
Common Mistakes in Responding to a Rule 86A Block
- Losing track of the start date: sub-rule (3) counts the one year from the day the restriction was imposed, and the portal's automatic unblock reaches active taxpayers only, so a cancelled or suspended registration needs its own follow-up.
- Replying without evidence: paragraph 3.4.1 links a fresh look at the credit to submissions backed by material evidence, so a bare denial gives the officer nothing to act on.
- Not testing the amount: paragraph 3.3.2 says the amount disallowed should not be more than the credit believed fraudulently availed or ineligible, so a wider block is itself a point to raise.
- Skipping the ledger links: the Attachment and Description links show any document the official uploaded and who acted, which a reply should address.
- Confusing it with Rule 86B: that separate restriction needs no officer action. Rule 86B applies in any month in which the value of taxable supply, other than exempt and zero-rated supply, exceeds ₹50 lakh, and caps credit use at ninety-nine per cent of output tax, subject to the exceptions it lists.
