Check GSTR 2B and IMS
Confirm whether the invoice is absent, pending, rejected or reported in another period.
Review check gstr 2b and ims at invoice level. Match GSTIN, invoice number, date, taxable value, tax rate and tax heads with the books. Total-level matching can hide a wrong recipient, duplicate invoice or credit note reported in another period.
Contact the supplier with evidence
Share invoice number, date, GSTIN and tax amount. Ask for correction in the next available filing.
Review contact the supplier with evidence at invoice level. Match GSTIN, invoice number, date, taxable value, tax rate and tax heads with the books. Total-level matching can hide a wrong recipient, duplicate invoice or credit note reported in another period.
Review legal conditions
Receipt of goods or services, possession of invoice, business use, payment and non-blocked status still matter.
Review review legal conditions at invoice level. Match GSTIN, invoice number, date, taxable value, tax rate and tax heads with the books. Total-level matching can hide a wrong recipient, duplicate invoice or credit note reported in another period.
Control vendors
Age missing invoices, hold escalation reviews and include compliance clauses in procurement processes.
Review control vendors at invoice level. Match GSTIN, invoice number, date, taxable value, tax rate and tax heads with the books. Total-level matching can hide a wrong recipient, duplicate invoice or credit note reported in another period.
How to check the issue correctly
Download the relevant returns and compare them with the sales or purchase register invoice by invoice. Create four groups: matched, missing from the portal, missing from books and present with different values. This is more useful than comparing only monthly totals.
For every unmatched item, record the GSTIN, invoice number, date, taxable value, GST amount, reason and proposed correction period. Review ITC eligibility separately because an invoice appearing in GSTR-2B does not automatically make the credit eligible.
Step by step action plan
1. Review check gstr 2b and ims and collect the supporting record.
2. Review contact the supplier with evidence and collect the supporting record.
3. Review review legal conditions and collect the supporting record.
4. Review control vendors and collect the supporting record.
Practical example
A purchase of Rs 1 lakh carries Rs 18,000 GST, but the supplier omitted it. The buyer should not treat Rs 18,000 as automatically available credit; track reporting and apply the law for the relevant period.
The lesson is to trace the issue before correcting it. Start with the source record, calculate the exact effect and keep proof of the action taken. If the correction changes tax, credit, refund or statutory status, recheck the portal after processing rather than assuming submission completed the matter.
Documents to keep ready
-
Sales and purchase registers
-
Tax invoices and credit or debit notes
-
GSTR-1, GSTR-3B and GSTR-2B downloads
-
IMS action report where relevant
-
Electronic liability, credit and cash ledgers
Use clear filenames that include the year, form or statement and date. Keep the final filed version separately from drafts so the wrong document is not used later.
Common mistakes and why they matter
-
Ignoring check gstr 2b and ims when deciding the next step
-
Ignoring contact the supplier with evidence when deciding the next step
-
Ignoring review legal conditions when deciding the next step
-
Ignoring control vendors when deciding the next step
These mistakes usually happen when the final amount is checked without tracing the supporting record. Confirm the year, form, source data and portal status before filing a correction or response.
When to get professional help
Get help when the difference affects tax payment, a notice or suspension is involved, prior-year amendment time is closing, or several GSTINs or periods are affected.
Professional review is especially useful when the case affects more than one return, another person must correct data, or the response period is short. Share the full communication and supporting records rather than only a screenshot of the final amount.
Final thoughts
The safest approach is simple. Identify the correct year, compare the official portal record with your documents, calculate the exact difference and use the remedy designed for that difference. Save every acknowledgement and check the status again after processing.

Frequently Asked Questions
