Rule 86A: When the GST Officer Blocks Your Electronic Credit Ledger

The short answer

Rule 86A of the CGST Rules lets the Commissioner, or an officer he authorises (not below the rank of Assistant Commissioner), stop you from using input tax credit that is sitting in your electronic credit ledger, when he has reasons to believe that the credit was availed fraudulently or is not eligible. The credit is not taken away; it is frozen. You cannot use the blocked amount to pay output tax or claim it as a refund until the officer lifts the block, or until one year passes from the date it was imposed, whichever comes first.

It is a protective step, used before any demand is raised, mostly in cases of fake invoices and circular trading. But it hits genuine businesses too when a supplier turns out to be non-existent, so every accountant should know how it works.

The five grounds for blocking

The officer must have reasons to believe that the credit was availed in one of these ways:

• Fake or absent supplier — on an invoice issued by a person who is not found at the registered place of business, or does not exist.
• No goods or services received — the invoice is there but nothing was actually supplied.
• Tax not paid to the government — the supplier charged GST on the invoice but did not deposit it.
• The buyer is not found — the registered person claiming the credit is not found at their own place of business.
• No document at all — credit taken without an invoice, debit note or other valid document under Rule 36.

The reasons have to be recorded in writing. A general suspicion, or a supplier simply being late with returns, is not enough.

Who can block, and how much

CBIC’s guidelines of 2 November 2021 on Rule 86A ask officers to act only on material evidence and to take the approval of a senior officer depending on the amount being blocked:

Amount of credit to be blocked	Who decides
Up to ₹1 crore	Deputy or Assistant Commissioner
₹1 crore to ₹5 crore	Additional or Joint Commissioner
Above ₹5 crore	Principal Commissioner or Commissioner

The guidelines also say the officer should consider the taxpayer’s reply and documents before or soon after blocking, and should not block mechanically on the basis of a list received from another office.

What happens while the credit is blocked

• The blocked amount stays in your electronic credit ledger, but the portal will not let you debit it.
• You can still use the unblocked credit and your cash ledger normally.
• Your GSTR-3B is still due every month. If the free credit is not enough, the balance must be paid in cash, or interest under Section 50 and late fees start running.
• You cannot claim the blocked credit as a refund (for example, an export refund of accumulated ITC).
• The officer can lift the block once he is satisfied the conditions no longer exist (Rule 86A(2)). Otherwise it lapses after one year from the date it was imposed (Rule 86A(3)).

A worked example

Meridian Traders has ₹4,20,000 of ITC in its credit ledger. During a verification, the department finds that one supplier, from whom Meridian took ₹3,00,000 of credit, is not functioning at its registered address. The officer blocks ₹3,00,000 under Rule 86A.

Item	Amount
ITC in the credit ledger	₹4,20,000
Blocked under Rule 86A	₹3,00,000
Credit Meridian can use	₹1,20,000
October output tax (GSTR-3B)	₹2,50,000
Paid from credit	₹1,20,000
Must be paid in cash	₹1,30,000

If Meridian had planned to pay October entirely from credit, it now needs ₹1,30,000 in cash by the GSTR-3B due date. That cash flow shock is why blocking is taken so seriously.

Negative blocking

Sometimes the credit in question has already been used, and the officer blocks an amount larger than the current balance, so the ledger shows a negative figure that eats up future credit. Several High Courts, including the Delhi High Court in 2024, have held that Rule 86A only allows blocking of credit that is available in the ledger when the block is imposed. If you face this, take professional advice; it is usually challenged through a writ petition.

How to get the credit unblocked

• Find out why. Ask the jurisdictional officer for the reasons recorded; you are entitled to know the ground.
• Give evidence, quickly. Tax invoices, e-way bills, lorry receipts, goods received notes, bank payment proofs, the supplier’s GSTIN status and filed GSTR-1, and your GSTR-2B showing the invoices.
• Write a representation asking the officer to withdraw the restriction under Rule 86A(2).
• Keep paying in cash meanwhile so your own returns stay clean.
• If it is arbitrary or excessive, a writ petition before the High Court is the usual remedy, since there is no separate appeal form for a Rule 86A restriction.

Rule 86A is not the same as…

• Section 17(5) blocked credits — those are never available (motor cars, food, club fees and so on); see blocked credits under Section 17(5). Rule 86A freezes credit that would otherwise be usable.
• Rule 86B — the rule that makes some businesses pay 1% of output tax in cash; see Rule 86B.
• A demand — blocking only freezes the credit. Recovering it needs a show cause notice and an order (see GST demand notices).
