Review the resulting IMS entry and GSTR-2B before filing your GSTR-3B. Separately check whether the credit meets the statutory conditions for the relevant tax period: a corrected portal entry does not, by itself, establish that you are entitled to claim ITC.
Start by identifying the exact mismatch
Compare the supplier’s tax invoice or debit/credit note with your purchase register, the relevant GSTR-2B, and the corresponding IMS record. GSTR-1 is the supplier’s route for reporting outward supplies; GSTR-2B is the recipient’s static statement for period-based reconciliation. The GST Portal’s GSTR-1 guide and GSTR-2B advisory describe these roles.

- Supplier GSTIN and your recipient GSTIN
- Invoice or note number and date
- Taxable value and tax amount
- Place of supply and tax head
- Whether a credit note, debit note, or later amendment explains the difference
- Whether the purchase was actually received, recorded, and not duplicated or otherwise ineligible
GSTR-2A may show changing supplier details, but do not treat an entry there as a substitute for reconciling the relevant GSTR-2B and your books. A mismatch alone proves neither that the supplier acted improperly nor that you can claim the credit.
Match the problem to the correction needed
| What you find | What to do |
|---|---|
| Invoice absent or filed late | Ask the supplier to verify whether it was omitted and to report it through the applicable return workflow. Check the next applicable GSTR-2B for the corrected record. |
| Your GSTIN is wrong | Send the supplier the correct GSTIN and invoice reference, and ask for the record to be corrected. Keep documents linking the invoice to the actual purchase and recipient registration. |
| Invoice number, date, value, or tax is wrong | Identify the specific field that differs from the source invoice and ask the supplier to amend it. |
| A credit/debit note or amendment is involved | Check whether the difference comes from the original invoice or the subsequent adjustment, then review the matching IMS record. |
| Tax head or place of supply differs | Verify the transaction and place-of-supply details against the invoice and underlying facts before deciding how to treat the credit. |
| Your own books or return contain a duplicate or ineligible claim | Correct your own records and return treatment; a supplier-side correction does not resolve a recipient-side error. |
Ask the supplier for a specific correction
Send a concise discrepancy note identifying the relevant tax period, invoice number and date, both GSTINs, taxable value and tax, and the exact field that is missing or incorrect. Include a record or screenshot of the GSTR-2B/IMS discrepancy if useful. Ask the supplier to check its filed data and make the appropriate correction; the supplier is responsible for reporting its outward-supply information accurately.
#1 Best Overall
The GST Portal’s GSTR-1 guide describes optional GSTR-1A as a way for a supplier to add or correct records for the same tax period before filing that period’s GSTR-3B. The guide says changes made through GSTR-1A are reflected in the recipient’s next-period GSTR-2B. Whether that route is available depends on the supplier’s filing status and the live portal workflow.
Review IMS and GSTR-2B before filing
The GST Portal’s revised IMS advisory describes recipient actions and their effect on the statement:
- Accept: The record enters GSTR-2B’s “ITC Available” area; eligible ITC auto-populates in GSTR-3B.
- Reject: The record appears in the rejected section and does not auto-populate as available credit.
- Pending: For eligible document types, the record stays out of that month’s GSTR-2B/GSTR-3B for action later.
- No action: The advisory says records with no action are treated as deemed accepted when GSTR-2B is generated.
Check the document type and current portal screen before acting, since the advisory notes exceptions to pending action. If you act after a draft GSTR-2B has been generated, the advisory says to recompute GSTR-2B before filing GSTR-3B. It also says you cannot take IMS action for that month after filing its GSTR-3B. Do not accept a record simply to make an amount appear in the return; reconcile it to the invoice and the underlying transaction.
Check ITC eligibility separately from the portal match
A supplier’s promise to correct a return, or an invoice’s appearance in GSTR-2B, does not by itself satisfy every condition for claiming ITC. Check the rules that apply to the tax period, keep the prescribed invoice or other tax-paying document, and retain evidence that goods or services were received and payment was made. The CBIC CGST Rules compilation states that, for covered invoices, supplier furnishing in GSTR-1/IFF and communication in GSTR-2B are relevant conditions. It also sets out a 180-day payment-related reversal mechanism, subject to its terms and exceptions. That compilation is dated; verify later amendments and the law applicable to your period before relying on it.

If you receive a DRC-01C intimation
DRC-01C is a separate, return-level issue—not simply an informal notice that one supplier invoice is missing. The GST Portal’s DRC-01C manual says an ITC difference between GSTR-2B and ITC claimed in GSTR-3B/3BQ that exceeds a predefined limit can trigger an intimation. The cited manual does not state a universal numerical threshold.
- Open the intimation in the GST Portal and read the period, difference, response instructions, and deadline shown there.
- Reconcile the GSTR-2B and GSTR-3B/3BQ amounts against your purchase register, supplier records, and supporting documents.
- Submit the required reconciliation and explanation in Part B through the portal workflow.
- Keep the submitted response and supporting records with your return documentation.
The manual warns that failure to file the Part B response prevents filing GSTR-1/IFF for the subsequent tax period. Follow the live notice and portal instructions; do not infer a deadline or threshold from the general description.

CBIC Circular 183/15/2022-GST, dated 27 December 2022, addresses specified differences between ITC claimed in GSTR-3B and reflected in GSTR-2A for FY 2017-18 and FY 2018-19. It includes a procedure for covered cases, including certain supplier reporting errors involving a wrong GSTIN, and discusses verification of the invoice or debit note, receipt of goods or services, and payment to the supplier. It is not a blanket permission or general remedy for mismatches in later tax periods.
