If the supplier invoice covers more goods or value than you actually received, do not “partially rewrite” the supplier’s invoice inside your own IMS record. Match what was received, identify rejected/short quantity, and ask the supplier for the appropriate commercial/GST correction such as a credit note or amendment. Claim only ITC that satisfies the legal conditions, and reconcile the supplier’s eventual corrected document so the books and IMS do not diverge.
What this means for the business owner
If the supplier invoice covers more goods or value than you actually received, do not “partially rewrite” the supplier’s invoice inside your own IMS record. Match what was received, identify rejected/short quantity, and ask the supplier for the appropriate commercial/GST correction such as a credit note or amendment. Claim only ITC that satisfies the legal conditions, and reconcile the supplier’s eventual corrected document so the books and IMS do not diverge.
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
Short supply, quality rejection, partial cancellation or invoicing before final quantity confirmation can create the mismatch.
What should be checked immediately
Do not start with a correction entry. First collect the minimum evidence needed to prove what actually happened.
| Mismatch | Recipient control | Supplier correction |
|---|---|---|
| Short quantity | Document actual receipt | Credit note / corrected invoice as legally appropriate |
| Price dispute | Do not self-edit supplier invoice | Commercial/GST correction |
| Damaged/rejected goods | Track return and ITC | Credit note |
What to do now
Retain GRN/quantity evidence, inspect invoice/PO, decide ITC eligibility for what was actually received, and obtain supplier correction. Track the credit note/amendment in IMS/2B.
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 is a recipient action layer on supplier-reported documents; it does not let the recipient unilaterally change the supplier’s invoice value. Section 16 conditions and actual receipt of goods/services remain relevant to ITC.
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
A supplier invoices 100 units but 20 are rejected on receipt. The recipient should not simply accept full ITC because the invoice exists; it should document actual receipt and obtain the supplier’s correction for the rejected value.
What happens if the problem is ignored
Claiming excess ITC can create later reversal/interest exposure; informal partial adjustments without supplier correction create audit-trail gaps.
What TargoLegal checks before filing or responding
TargoLegal matches PO, GRN, invoice, rejected quantity, credit note and IMS/2B before finalising ITC.
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
Short supply but full GST invoice? Send the invoice and rejected value.
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: Purchase order, Supplier invoice, GRN/receipt quantity.
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.
