GST input tax credit reconciliation: a GSTR-2B checklist for Indian MSMEs
Reconcile supplier invoices, your purchase register and GSTR-2B before reporting eligible GST input tax credit in GSTR-3B.
In this guide
What is GSTR-2B and how should a business use it?
GSTR-2B is a read-only, auto-drafted statement that brings together documents reported by suppliers and other systems for a tax period. It is not a return you file, and the GST Portal advises taxpayers to reconcile it with their own books. Use it as a comparison tool, then check legal eligibility, reversals, reverse-charge tax and duplicate claims before reporting credit in GSTR-3B.
Download the statement for the correct GSTIN and tax period
After the portal generates the statement, download its available summary and document details for the same registration and period you are closing. Check the selected GSTIN, month or quarter and generation date. If the report is incomplete or a supplier files later, the document may appear in a later statement; keep a follow-up list instead of editing the read-only statement.
Compare three records, not just the portal totals
Match GSTR-2B against your purchase register and the original invoice, debit note, bill of entry or other evidence. Compare supplier GSTIN, document number and date, taxable value, tax amount, place of supply and whether the purchase belongs to the business. A matching amount with a wrong supplier or duplicate invoice still needs investigation.
Treat portal availability and legal eligibility as separate checks
The statement shows what has been reported through specified systems; it does not decide every ITC condition under GST law. Check the current Act and Rules for business use, restrictions, time limits, payment or other conditions and reversals. Do not claim credit solely because it appears in GSTR-2B, and do not assume every missing document can be claimed.
| Document or supplier | Difference | Action and owner | Resolution period |
|---|---|---|---|
| Invoice absent from GSTR-2B | |||
| Amount, GSTIN or place-of-supply mismatch | |||
| Possible duplicate, credit note or reversal | |||
| Import or reverse-charge item | |||
| Credit approved or excluded after review |
Resolve common differences before preparing GSTR-3B
Invoice missing because the supplier has not reported it
Check whether the invoice is valid, received and recorded in the right period. Contact the supplier with the invoice number and GSTIN and ask for a written correction or filing plan. Track the item until the relevant statement updates, then apply the current eligibility and time-limit rules; a supplier promise alone is not a substitute for tax review.
Amount, tax or GSTIN does not match
Compare the supplier's invoice with the purchase order, goods-received note or service evidence and your ledger. Ask the supplier to correct an incorrect return or document where appropriate. Do not silently change the supplier's record in your books to force a match; preserve the original and the correction trail.
Credit note, amendment or duplicate needs separate treatment
Link credit and debit notes to the original invoice, review amended documents and check whether a previously taken amount needs reversal or adjustment. Search the purchase register for duplicate invoice numbers and repeated uploads. Keep one decision record for each discrepancy so the same credit is not claimed twice across periods.
Imports and reverse-charge entries need their own evidence
For imported goods, compare the bill of entry and import tax evidence with the portal statement and accounting record; some import data can arrive through customs systems. For reverse charge, distinguish tax payable from any credit that may be available after payment and eligibility review. Ask a tax adviser to confirm unusual import, courier or cross-border service cases.
Build an ITC close process that can be repeated
Set a cutoff and assign one reviewer
Choose an internal date before return filing to close purchase invoices, obtain supplier statements and review GSTR-2B. Assign one person to prepare the reconciliation and another authorised reviewer to approve material credit, reversals and unresolved items. For a very small business, the owner can review the accountant's exception list.
Record credit taken, reversed, pending or excluded
Use clear status labels and retain the reason, evidence, period and reviewer for each line. Carry eligible unresolved documents forward only as current rules allow. Record reversals and later reclaims separately so a reversal does not become a permanent loss or an accidental double claim.
Keep tax files private and retrievable
Store supplier invoices, import records, reconciliation exports, emails and filed returns in a controlled folder with backups. Restrict GST credentials and customer or supplier tax details to authorised people. A clear file name using period and GSTIN helps answer a notice or accountant query without searching every device.
GSTR-2B and input tax credit questions
Do I file GSTR-2B?
No. The GST Portal describes GSTR-2B as a read-only auto-drafted statement. Use it to reconcile and review credit before filing the relevant return.
Can I claim every credit shown as available in GSTR-2B?
No. Portal availability is not the only eligibility test. Self-assess the current GST law, business-use requirements, restrictions and reversal obligations before claiming an amount.
What if a supplier invoice is missing?
Check the invoice and books, contact the supplier with the exact mismatch and track the correction. Review the current rules and time limit before deciding when or whether the credit can be taken.
Can I change information inside GSTR-2B?
No. The portal FAQ describes the statement as read-only. Correct your records and use the appropriate supplier or return process; do not try to alter the downloaded statement.
