Rule 36 Documents and GSTR-2B Matching for ITC

Updated 11 October 2026 · Fact-checked

Rule 36 of the CGST Rules lists the documents on which you can claim input tax credit: supplier invoice, debit note, bill of entry, and ISD documents. Under Rule 36(4), you can claim credit on invoices and debit notes only if the supplier has reported them in GSTR-1 and the credit appears in your GSTR-2B.

Understand Matching, Reconciliation and Credit Documents

Input tax credit is not claimed on your word alone. You need a valid document, and the supplier must have reported the transaction. Rule 36 sets out both ideas: what documents you may use, and what particulars and matching conditions apply.

Rule 36(1) names the documents. These are an invoice issued by the supplier under section 31, an invoice issued under section 31(3)(f) (reverse charge supplies from unregistered persons) subject to payment of tax, a debit note issued by a supplier under section 34, a bill of entry or similar Customs document for assessment of integrated tax on imports, and an Input Service Distributor invoice, credit note or document issued under rule 54(1).

Rule 36(2) says the document must carry all applicable particulars given in Chapter VI. A proviso gives relief. If the document lacks some particulars but shows the tax charged, description of goods or services, total value of supply, GSTIN of supplier and recipient, and place of supply for inter-State supply, credit may still be availed.

Rule 36(3) bars credit on tax paid under an order confirming a demand for fraud, wilful misstatement or suppression of facts under section 74.

Rule 36(4) is the matching rule. It applies to invoices and debit notes whose details must be furnished under section 37(1). You can avail credit only if (a) the supplier has furnished the details in GSTR-1 (as amended in GSTR-1A, if any) or through the invoice furnishing facility, and (b) the credit in respect of those documents has been communicated to you in GSTR-2B. The old 5% provisional credit cap was replaced from 1 January 2022 by this strict condition. It is no longer in force.

GSTR-2A is a dynamic view of your inward supplies. It changes whenever suppliers file or amend. GSTR-2B is a static statement for a month, generated from supplier filings up to a cut-off, and it tells you the credit available. Rule 36(4) refers to GSTR-2B, so that is your base for claims.

Key rules to remember

Documents for ITC (Rule 36(1))
Supplier invoice | section 31(3)(f) invoice (with tax paid) | supplier debit note | bill of entry | ISD invoice or credit note
Learn all five. A credit note is not in the list for the recipient, except an ISD credit note.
Particulars condition (Rule 36(2))
All applicable Chapter VI particulars; or, under the proviso, tax amount + description + total value + GSTINs + place of supply (inter-State)
The proviso saves a document that is missing other particulars.
Matching condition (Rule 36(4))
ITC allowed only if (a) supplier furnished details in GSTR-1 / GSTR-1A / IFF AND (b) credit communicated in GSTR-2B
Both limbs must be met. It applies to documents covered by section 37(1).
Fraud bar (Rule 36(3))
No ITC on tax paid under an order confirming demand for fraud, wilful misstatement or suppression of facts under section 74
Applies to tax paid in pursuance of the order.

How to solve Matching, Reconciliation and Credit Documents questions

Use this order for any question on credit documents or matching.

  1. 1Identify the document held: invoice, debit note, bill of entry, ISD document or a reverse charge invoice.
  2. 2Check it falls within Rule 36(1). If not, no credit on that basis.
  3. 3Check particulars under Rule 36(2). If some are missing, test the proviso list.
  4. 4Check whether the document is covered by section 37(1) outward supply reporting. If yes, apply Rule 36(4).
  5. 5Test limb (a): did the supplier report it in GSTR-1 or GSTR-1A or IFF?
  6. 6Test limb (b): does the credit appear in your GSTR-2B for the period?
  7. 7Check Rule 36(3) if tax was paid under a section 74 order.
  8. 8State the conclusion: credit allowed, or not now, with the reason from the rule.

Quickest way: Four-check scan

When to use it: For MCQs and short case scenarios on whether ITC can be claimed.

  1. Is the document one of the five in Rule 36(1)?
  2. Are the key particulars present (tax, description, value, GSTINs, place of supply)?
  3. Is it in GSTR-2B? If not, no claim under Rule 36(4).
  4. Was the tax paid under a section 74 fraud order? If yes, no credit.

Common mistakes in Matching, Reconciliation and Credit Documents

  • Applying the old 5% provisional credit limit

    Older books and notes still show it.

    Fix: That text was substituted from 1 January 2022. Now credit depends on the invoice appearing in GSTR-2B.

  • Treating GSTR-2A and GSTR-2B as the same

    Both show supplier-reported data.

    Fix: GSTR-2A is dynamic and changes. GSTR-2B is static for a month. Rule 36(4) refers to GSTR-2B.

  • Rejecting a document that lacks some particulars

    Students stop at Rule 36(2) and ignore the proviso.

    Fix: Check the proviso. Tax amount, description, total value, GSTINs and place of supply for inter-State supply are enough.

  • Missing the second limb of Rule 36(4)

    Students check only that the supplier filed GSTR-1.

    Fix: Also confirm the credit was communicated in GSTR-2B.

  • Listing a credit note as a recipient's ITC document

    Credit notes feel like mirror images of debit notes.

    Fix: Rule 36(1) lists supplier debit notes and ISD credit notes only.

Worked examples

Example 1

Mehta Traders, Surat, holds a valid tax invoice from Shah Metals for goods with GST of ₹54,000. Shah Metals reported it in GSTR-1, but the credit does not appear in Mehta's GSTR-2B for the month. Can Mehta claim the credit in that month?

Show the solution
  1. The tax invoice is a valid document under Rule 36(1)(a).
  2. Rule 36(4) applies as the invoice is covered by section 37(1).
  3. Limb (a) is met: the supplier furnished details in GSTR-1.
  4. Limb (b) is not met: the credit has not been communicated in GSTR-2B.
  5. Both limbs are needed, so credit cannot be availed now.

Answer: Mehta cannot claim the ₹54,000 in that month. It can be availed once the credit is communicated in GSTR-2B.

Example 2

Kaveri Industries received an inter-State invoice showing the tax charged, description of goods, total value, both GSTINs and place of supply, but one other prescribed particular is missing. The invoice is in GSTR-2B. Is ITC allowed?

Show the solution
  1. The invoice is a Rule 36(1) document.
  2. Under Rule 36(2), all applicable particulars are required.
  3. The proviso allows credit if tax amount, description, total value, supplier and recipient GSTINs and place of supply (inter-State) are present.
  4. All these are present, so the proviso applies.
  5. Rule 36(4) is satisfied because the invoice is in GSTR-2B.

Answer: ITC is allowed under the proviso to Rule 36(2), subject to other conditions of eligibility.

Exam tips

  • Quote Rule 36(4) limbs separately: GSTR-1 reporting and GSTR-2B communication.
  • Write the document list from Rule 36(1) in full when asked for documents.
  • Do not mention the 5% cap as current law. If at all, call it historical.
  • In case scenarios, state the rule, apply it to the facts, then conclude in one line.
