To claim input tax credit (ITC) under India’s GST system, review the relevant period’s GSTR-2B, reconcile its entries with your invoices and books, independently check whether each credit is legally eligible, and report eligible amounts in GSTR-3B. An entry marked available in GSTR-2B is not, by itself, proof that you qualify to claim it.
What GSTR-2B does—and what it does not do
GSTR-2B is an auto-drafted, static, read-only ITC statement for a tax period. You do not file it. The GST Portal describes it as a tool to help taxpayers determine credit for the relevant GSTR-3B period.

It is assembled from documents and information reported through sources including suppliers’ or e-commerce operators’ GSTR-1, GSTR-1A or IFF; Input Service Distributor information in GSTR-6; GSTR-5; and import IGST details from ICEGATE. An entry shows that information has been reported into the system. It does not settle whether the recipient meets every legal condition for claiming that credit.

How to claim ITC: a period-by-period workflow
-
Open the relevant period’s GSTR-2B
Use the statement for the tax period you are preparing to report in GSTR-3B. GSTR-2B is a review document, not a return to submit.
-
Verify each entry against its source document and transaction
Check the invoice or other underlying document and confirm that it relates to your business records. Review the transaction itself rather than relying only on the statement’s summary or availability indication.
-
Reconcile GSTR-2B with your books
Match the statement against your purchase records. Investigate missing documents, amendments, credit notes and duplicate entries before filing. Do not claim the same document more than once.
-
Apply the legal eligibility test
Assess eligibility under the current CGST Act and Rules and the instructions applicable to your tax period. The GST Portal’s “ITC not available” marking covers specified situations, including documents treated as time-barred under section 16(4) and a specified supplier/place-of-supply state mismatch. The Portal cautions that other legal restrictions may not be reflected in that table. An “available” entry is therefore not a final entitlement decision.

Please review EULA and Privacy policy.The Portal guidance summarized here does not establish a complete eligibility checklist, all blocked-credit categories or the current statutory time limit. Check the current consolidated legislation and live GST Portal instructions before relying on a credit or a deadline.
-
Report eligible credit in GSTR-3B and make required adjustments
Use the applicable GSTR-3B fields for the tax period, following the live form instructions. Make reversals where required by the Act and Rules; do not treat an amount as claimable merely because it appears in GSTR-2B. For reverse-charge supplies, the GST Portal FAQ says the tax must first be paid and the credit may then be availed in GSTR-3B.
-
Keep a record of the decision
Keep the underlying document, relevant books entry, GSTR-2B comparison and the reason for claiming, not claiming or adjusting the amount together. If credit is reversed and later reclaimed, retain that history as well. The specific record-retention period is not established by the Portal guidance described here; check the applicable rules for it.
How to read an ITC entry in GSTR-2B
| What you see | What it establishes | What to do |
|---|---|---|
| An entry marked available | The document appears in the statement as available according to the Portal’s displayed criteria. It does not prove that every legal condition is met. | Match it to your document and books, then assess eligibility under the current law before reporting it. |
| An entry marked “ITC not available” | The Portal has applied a specified unavailability indicator. Its display does not cover every possible legal restriction. | Review the reason and the underlying facts; do not claim it without resolving the issue under current rules. |
| A document is missing, amended, duplicated or affected by a credit note | The statement and your records do not yet align, or an entry may have changed. | Reconcile the difference against source documents and supplier reporting, and avoid claiming a duplicate amount. |
Reverse charge, reversals and later reclaims
Reverse-charge ITC has an additional step: according to the GST Portal FAQ, pay the reverse-charge tax first; the credit may then be availed in GSTR-3B, subject to applicable eligibility requirements.

A reversal does not disappear from the compliance history if credit is later reclaimed. The GST Portal’s FY 2024-25 GSTR-9/9C FAQ gives a specific example: a taxpayer claimed ITC in March 2025, reversed it in that month because goods had not reached the factory, and reclaimed it in April 2025. The FAQ directs that example to specified GSTR-9 tables for FY 2024-25. It is an example for that fact pattern, not a blanket reporting rule for every reversal or reclaim; check the instructions for the relevant annual return and year.
Where to verify current requirements
The GST Portal’s GSTR-2B FAQ and advisory explain how to use the statement and warn that its unavailable-credit display captures only specified cases. They are useful for understanding the portal’s statement, but they do not replace the current consolidated CGST Act and Rules or the live instructions for the return period. Verify those sources when a claim depends on a statutory condition, restriction, time limit or reporting treatment that is not addressed by the Portal guidance.
