A line in GSTR-2B is useful evidence of supplier reporting, not proof by itself that the credit is lawful. The general deadline under section 16(4) is 30 November after the end of the relevant financial year, or the date you furnish the relevant annual return, whichever is earlier; check whether a specific exception applies.
How do I claim input tax credit under GST?
Assess eligibility invoice by invoice before relying on a portal match. Section 16 of the CGST Act sets out core conditions, while section 17 and other provisions restrict or apportion credit in specified cases. The result depends on the transaction and applicable law, including relevant IGST or state provisions.
Check the conditions for each document
- Valid document: Keep the prescribed tax invoice, debit note or other permitted document, and check that its details support the amount claimed.
- Business use: The purchase must be for, or intended for, business. Credit may need to be apportioned where goods or services are used partly for non-business purposes or for making exempt supplies.
- Receipt: Confirm that the goods or services were received. If goods arrive in lots or instalments, section 16 provides that credit is taken on receipt of the last lot or instalment.
- Supplier reporting and return: Check that the supplier furnished the document details and that they were communicated to you, and that you have furnished the required return.
- Tax and restrictions: Confirm the tax has been paid to the government as required and check blocked-credit rules and any other applicable restrictions. Do not claim tax on a component for which the law disallows credit, such as where depreciation has been claimed on the tax component of capital goods.
GSTR-2B can help establish that a supplier-reported document was communicated, but it does not establish receipt, business use, payment or the absence of a blocked-credit restriction. Keep the eligibility assessment with the invoice-level records rather than treating a portal status as the decision.
Separate ordinary purchases from reverse charge
Do not treat an inward supply reported as liable to reverse charge like an ordinary invoice on which the supplier charged tax. The recipient must account for and pay the reverse-charge tax as required; assess any resulting ITC separately under the applicable rules and return instructions.

How do I reconcile GSTR-2B with my books?
Compare the purchase register to the GSTR-2B for the relevant tax period at document level. The GST Portal describes GSTR-2B as a static, read-only statement that helps taxpayers prepare GSTR-3B; it is not a substitute for checking eligibility. The Portal FAQ describes monthly GSTR-2B generation on the 14th day of the succeeding month. Check the current portal schedule and relevant statement before closing a period.
Keep a document-level reconciliation record
A practical workbook—not a prescribed official form—can hold one line per invoice, debit note, credit note or amendment, with fields such as:
- Supplier GSTIN and name
- Invoice or note number, date and tax period
- Taxable value and tax split by applicable tax type, plus total tax
- Place of supply, where relevant
- Purchase-register status and GSTR-2B status
- Difference amount and eligibility or reversal status
- Action owner, follow-up evidence and resolution date
Use consistent document identifiers, preserve the original entries, and record how each difference was resolved. This makes it possible to distinguish a late supplier filing from a data-entry error or an ineligible claim.
Why is an invoice missing from GSTR-2B?
A missing line can reflect timing or a supplier reporting issue; it does not, by itself, prove either permanent ineligibility or entitlement to claim. Check the supplier’s filing status and the cut-off for the statement you are reviewing. A document furnished after the applicable cut-off may appear in a later open GSTR-2B.
Ask the supplier to furnish or correct missing or inaccurate details where appropriate, and retain the correspondence and any correction confirmation. Recheck a later statement before deciding how to report the amount. Track whether the credit has already been claimed, reversed or reclaimed so it is not claimed twice. If the statutory deadline is approaching, escalate the unresolved item promptly rather than assuming a later appearance will preserve eligibility.
What should I do if the ITC amount does not match?
Trace the difference to its source before changing a return. A mismatch may be caused by a supplier filing, a document detail, timing, an amendment, a credit note or the recipient’s own books. The appropriate action depends on which record is wrong and whether the credit is legally available.
| What you find | What to investigate | Practical next step |
|---|---|---|
| Invoice in books but missing from GSTR-2B | Supplier filing status and statement cut-off | Follow up with the supplier; preserve evidence and check a later open statement for the document. |
| Invoice appears, but GSTIN, number, date, value or tax differs | Compare the source invoice, purchase entry, supplier filing and any amendment | Correct your books if your entry is wrong; ask the supplier to amend its filing if its reported details are wrong. |
| Credit note or amendment changes the amount | Trace the original document and its adjustment together | Reconcile to the net position and prevent the original and amended figures from being counted as separate credit. |
| GSTR-2B marks an amount not available or restricted | Read the stated reason and test the applicable legal conditions | Resolve the stated issue, but separately check eligibility: the portal status covers only specified scenarios and may not flag every reason credit is unavailable. |
| Reverse-charge inward supply is listed | Whether the recipient has accounted for and paid the reverse-charge tax | Handle the liability and any eligible credit under the reverse-charge rules and the applicable GSTR-3B reporting instructions. |
| Portal and books agree, but eligibility is uncertain | Receipt, business use, exempt or non-business apportionment, blocked credits, payment and duplicate claims | Complete the legal review before claiming or retaining the credit; agreement between records does not settle eligibility. |
GST Portal e-invoicing guidance identifies manual recording differences, including invoice-number capture, as a possible matching problem. That is a reason to compare the source documents and reported details carefully—not to assume that either the supplier return or your books are automatically correct.
How should I report eligible credit and required reversals?
Use the relevant GSTR-2B as an input to the applicable GSTR-3B tables, then self-assess the amount to report. The GST Portal states that GSTR-2B is read-only and that system-populated fields in GSTR-3B are editable. An auto-populated amount is not a legal determination: adjust the return only after establishing what the underlying documents and rules require.

Record eligible ITC and make any required reversal or apportionment in the appropriate return fields under the current form instructions. Keep the invoice or debit note, evidence of receipt, books entry, reconciliation and resolution notes, supplier correspondence, calculations supporting reversals or reclaims, and the filed return. Those records should let another reviewer follow the amount from source document through reconciliation to the return.

What is the last date to claim ITC?
Under the general rule in section 16(4) of the CGST Act, ITC for an invoice or debit note must be taken by 30 November following the end of the relevant financial year, or by the date the relevant annual return is furnished, whichever is earlier. The annual-return date can therefore make the actual cut-off earlier than 30 November. Specific statutory provisions may alter the result for particular cases, so verify the current law for the transaction and financial year.
For example, for a document relating to financial year 2025–26, the general 30 November date falls on 30 November 2026. That is not a universal safe-harbour date: the relevant annual return may be furnished earlier, and applicable exceptions or other provisions must be checked. Schedule a review early enough to resolve supplier reporting, document and eligibility issues before the applicable deadline.
Monitor the 180-day supplier-payment condition
Section 16(2) also includes a condition to pay the supplier the value of the supply plus tax within 180 days, other than for supplies liable to reverse charge. Where the required amount remains unpaid after that period, the Act provides for payment of an amount equal to the ITC availed, with applicable interest, in the prescribed manner. Credit may be availed again when payment is made to the supplier. Check the applicable rules and facts, and track unpaid invoices so any required action is taken on time.
What records should I retain for a disputed or unresolved item?
Maintain one evidence trail per document, including:
- The prescribed source document and evidence that the supply was received
- The purchase-register entry and the relevant GSTR-2B line, or the documented absence of one
- The eligibility decision, including any business-use apportionment or blocked-credit analysis
- Supplier follow-up, corrections and the statement in which a late document appears
- The amount claimed, reversed or reclaimed and the return in which each action was reported
For a high-value or disputed claim, have a qualified Indian GST professional review the facts and applicable law. GST provisions, notifications, rules and portal instructions can change; use the current requirements for the relevant period rather than relying solely on a prior reconciliation or portal display.
