ITC Blocking Under Rule 86A: How to Get Input Tax Credit Unblocked

Input Tax Credit (ITC) blocking under Rule 86A can immediately affect a business’s cash flow. A taxpayer may log into the GST portal to file a return and discover that the Input Tax Credit (ITC) available in its Electronic Credit Ledger cannot be used to discharge its GST liability.

Rule 86A of the CGST Rules, 2017 permits the specified authority to restrict the use of ITC where there are reasons to believe that the credit has been fraudulently availed or is ineligible on the grounds specified in the rule. However, the power is subject to important legal limits. Courts have held that Rule 86A cannot be used to create a negative balance by blocking ITC beyond the credit actually available in the Electronic Credit Ledger.

What Rule 86A permits

Rule 86A of the Central Goods and Services Tax Rules, 2017 empowers the Commissioner, or an officer authorised by him not below the rank the rule specifies, having reasons to believe that credit available in the Electronic Credit Ledger has been fraudulently availed or is ineligible on the grounds the rule lists, to disallow debit of an amount equivalent to such credit.

The grounds are specific. They concern credit availed on invoices issued by a supplier found to be non-existent or not conducting business from the registered place; credit availed on invoices without receipt of goods or services; credit where the tax has not been paid to the Government; credit availed by a registered person found non-existent; and credit availed without the invoice or debit note being in possession.

Two features of the rule define its character. It is a preventive measure, not a recovery mechanism — it operates outside the adjudicatory machinery in Sections 73, 74 and 74A and the recovery provisions in Section 79. And it is temporary: Rule 86A(3) provides that the restriction shall cease to have effect after the expiry of one year from the date of imposition.

The two limits the courts have enforced

Limit 1: The one-year cap is absolute.

Courts have held that the restriction lapses automatically on expiry of one year, by operation of law, and that the department cannot continue it. The Bombay High Court so held in NZS Traders Pvt. Ltd. v. Union of India, Writ Petition No. 4815 of 2024, by order dated 25 March 2026, where credit had been blocked in February 2024 and the restriction continued past the year; the Court held that Rule 86A(3) mandates that the restriction cannot continue beyond one year from imposition, and that on expiry the blocking ceases to operate automatically. The Delhi High Court has taken the same view.

The practical implication is direct: if the block is more than a year old, it has lapsed as a matter of law, and the taxpayer is entitled to have the ledger unblocked without demonstrating anything further about the merits.

Limit 2: Negative blocking is impermissible.

Officers had taken to blocking amounts exceeding the credit actually available, producing a negative balance in the ledger and, in effect, capturing credit that had not yet accrued.

In Best Crop Science Pvt. Ltd. v. Principal Commissioner, CGST, decided by the Delhi High Court on 24 September 2024, the Court analysed Rule 86A and held that it permits blocking only to the extent of credit available in the ledger at the time; that the rule is not a machinery provision for recovery; that it cannot be read as requiring the ledger to be replenished; and that negative blocking amounts to de facto recovery without due process.

That position has been followed and reinforced. The Delhi High Court applied it in Kings Security Guard Services Private Limited v. Deputy Director, DGGI, decided 4 December 2024, and the Supreme Court declined to interfere with that ruling by order dated 16 May 2025. The Punjab and Haryana High Court adopted the same view in M/s Shyam Sunder Strips v. Union of India and connected matters decided on 4 November 2025, noting that the High Courts of Gujarat, Delhi, Telangana and Bombay had reached the same conclusion.

The consequence is that where the ledger balance was nil or insufficient at the time of the order, invoking Rule 86A to that extent is without jurisdiction.

Grounds to Challenge ITC Blocking

Absence of reasons to believe. The rule requires reasons to believe, formed on material. A block imposed mechanically, on the basis of a communication about a supplier and nothing more, is open to challenge. The taxpayer is entitled to know the basis, and the CBIC has issued guidelines on the exercise of the power emphasising that it should be founded on material evidence and not on mere suspicion.

Absence of any order or communication. Blocking is frequently discovered only when the portal refuses a debit. Where no order has been communicated and no reasons disclosed, the action is vulnerable on natural justice grounds.

Blocking by an officer below the authorised rank, or in respect of a ground outside those the rule specifies.

How to Unblock ITC Blocked Under Rule 86A

If ITC has been blocked under Rule 86A, the taxpayer should first verify the basis and duration of the restriction. The following steps can help determine whether the credit can be released:

Step 1 — Establish the facts. Ascertain the date of blocking, the amount, the officer concerned and the ground relied upon. If no order is available, seek it in writing.

Step 2 — Check the two hard limits. Has one year passed since imposition? Did the ledger hold sufficient credit at the time? Either answer may resolve the matter without reaching the merits.

Step 3 — Apply to the Commissioner for release. Rule 86A(2) provides that the authority may, on being satisfied that the conditions for disallowing debit no longer exist, allow such debit. A written representation setting out the supplier’s compliance record, the invoices, the proof of receipt of goods or services, the payment made to the supplier and the tax discharged should be filed.

Step 4 — Writ petition under Article 226. Because Rule 86A produces no appealable order, the writ jurisdiction is the effective remedy, and High Courts have entertained such petitions readily. This is one of the clearer cases in GST practice where a writ is appropriate at first instance rather than as a last resort.

Practical Points on ITC Blocking Under Rule 86A

Monitor the ledger. Blocking is often discovered late, and the one-year period runs from imposition regardless of when it was noticed.

Preserve the supplier documentation. Most blocks are triggered by something on the supplier’s side. Invoices, e-way bills, transport documents, proof of payment through banking channels and the supplier’s filing history are what answer the allegation.

Distinguish blocking from a demand. Rule 86A does not determine liability. Where the department believes credit was wrongly availed, it must proceed by way of a show cause notice and adjudication under Section 73, 74 or 74A. Blocking is not a shortcut around that process — which is precisely what the negative-blocking line of cases establishes.
