If you accepted the wrong invoice in IMS, first check whether the IMS action can still be changed for that record and whether GSTR-2B has already been recomputed/finalised for the relevant workflow. Do not assume “Accepted” makes the ITC legally eligible. If the invoice is not yours or is incorrect, supplier amendment and the next available IMS/2B reconciliation may be needed before GSTR-3B is finalised.
What this means for the business owner
If you accepted the wrong invoice in IMS, first check whether the IMS action can still be changed for that record and whether GSTR-2B has already been recomputed/finalised for the relevant workflow. Do not assume “Accepted” makes the ITC legally eligible. If the invoice is not yours or is incorrect, supplier amendment and the next available IMS/2B reconciliation may be needed before GSTR-3B is finalised.
The return/application history and underlying source records should tell one consistent story before any correction, payment or clarification is submitted.
Who should use this guide
This guide is for taxpayers facing the exact fact pattern in the title. It is especially useful when the portal and your books/documents do not agree, when another person handled the original filing, or when a current application/return deadline is approaching.
Why this problem usually happens
Mistakes happen when finance teams bulk-act on IMS without matching books or when supplier master data is wrong.
What should be checked immediately
Do not start with a correction entry. First collect the minimum evidence needed to prove what actually happened.
| Status | Meaning for review | Next question |
|---|---|---|
| Accepted | Record accepted in IMS workflow | Is it legally yours and eligible? |
| Rejected | Record rejected | Was rejection factually correct? |
| Pending | Decision deferred where allowed | Does time limit/eligibility still permit later action? |
What to do now
Download the relevant IMS data, identify action date/status, match the purchase register and 2B, and determine whether the record can be changed now or must be corrected through supplier amendment/later period. Keep a written action log.
Before submission, the client should receive a concise summary of the problem, the proposed tax/ITC/registration treatment, payment impact and any unresolved item. After submission, keep the ARN/order/acknowledgement and filed copy.
The 2026 legal and portal position
IMS actions influence the recipient-side GST data workflow, but ITC eligibility still comes from the CGST Act and transaction facts. Current GST Portal advisories explain Accept, Reject and Pending behaviour and recipient actions.
GST Portal workflows, notifications and due-date extensions can change. The official sources below were checked for this article on 19 August 2026; recheck them immediately before filing if the matter is time-sensitive.
A realistic hypothetical
An accounts user accepts an invoice with the correct vendor name but wrong GSTIN/value. Before 3B, the error is discovered. The team should not simply claim ITC because IMS says Accepted; it should reconcile the actual invoice and supplier correction.
What happens if the problem is ignored
An uncorrected IMS action can flow into 2B/reconciliation and make a later reversal or supplier amendment harder to follow.
What TargoLegal checks before filing or responding
TargoLegal checks the IMS snapshot, GSTR-2B, actual invoice and supplier action, then maps the correction to the next return decision.
Before filing
Documents received, missing items, reconciliation difference, legal/portal route, payment impact and client approval.
After filing
Filed copy, ARN/acknowledgement, payment proof and a short open-items list for the next period.
What to send for a first review
Made an IMS mistake? Send the invoice type and return period.
Related questions
What should I send first?
Send the GSTIN/ARN, the exact period or application stage, and the document that shows the problem. For this topic, the most useful starting point is: IMS period and action status, Actual invoice, Purchase register.
Can I fix this by making an adjustment in the next return?
Not automatically. A later adjustment is appropriate only when the GST law and current portal workflow allow it and the original error has been reconciled.
Should I rely only on what the GST Portal auto-populates?
No. Portal data is essential evidence, but the taxpayer remains responsible for reconciling it with books, invoices and the applicable legal conditions.
What should I keep after the correction or filing?
Keep the filed return/form, ARN or acknowledgement, payment evidence, reconciliation working and any supplier/customer correspondence that explains the change.
When should professional review be considered?
Use professional review where the issue affects material tax or ITC, several periods, a registration notice, refund, e-invoicing, cancellation/revocation or a customer’s credit.
