For a GST credit-mismatch query, build a transaction file showing what was purchased, when it was received, how it was reported by the supplier and when credit was actually claimed or reversed. Separate a statement mismatch from a legal eligibility conclusion. An invoice in books, a supplier promise or a portal match cannot by itself answer every condition for input tax credit.
Define the queried credit population
Record the GSTIN, tax period, tax heads and comparison used in the communication. Identify whether the matter is a DRC-01C intimation under rule 88D, scrutiny or another proceeding.
Notification 38/2023 introduced the relevant rule 88D framework and related return-compliance restrictions. Read the actual communication and current process rather than borrowing a response period or threshold from an informal article.
Save the relevant inward-statement extract and filed GSTR-3B credit details. Historical periods can involve different legal and reporting requirements, so do not assume a current statement rule applied unchanged to an earlier year.
Build one row per document
Include supplier GSTIN, invoice number and date, taxable value, tax by head, purchase category, receipt date, claim period and amendment or reversal history. Normalise spaces and punctuation for matching, while retaining the original document identifiers.
A supplier may upload an invoice later or amend its number. Keep both the original and later reporting references. Do not count the amended record as a second purchase merely because its matching key changed.
Separate imports, reverse-charge items, input-service-distributor documents and other categories requiring different supporting records. One domestic purchase-invoice checklist will not fit every credit source.
An illustrative difference analysis
A Mysuru manufacturer’s queried return credit is ₹2,40,000, while the compared inward-statement amount is ₹2,10,000. The difference is ₹30,000.
| Item identified | Illustrative tax ₹ | Evidence and question |
|---|---|---|
| Supplier reporting in a later identified period | 18,000 | Filing trail and applicable period conditions |
| Duplicate credit claim in the buyer’s return working | 7,200 | Claim and reversal records |
| Unmatched purchase still under investigation | 4,800 | Invoice, receipt and supplier follow-up |
| Total difference | 30,000 | Bridge to the queried amount |
The ₹18,000 is not automatically eligible simply because the supplier later reports it. The ₹7,200 needs the appropriate corrective assessment. The ₹4,800 should remain an open question rather than be absorbed into “timing.”
Establish receipt and business purpose
For goods, connect the invoice with purchase order, delivery document, goods-receipt record, stock entry and transport evidence where relevant. For services, retain the agreement, deliverables, work confirmation and period of performance.
Payment proof supports settlement but does not prove that goods arrived or services were received. Conversely, receipt evidence does not establish that every tax-credit condition is satisfied.
Record the business use and category of expenditure. Personal consumption, restricted categories and exempt-use allocation can require a different conclusion from an ordinary eligible business purchase.
Track credit claimed, reversed and reclaimed
Reconcile the purchase register with actual return claims. A book input-GST debit can exist before credit is availed, while a return may contain manual adjustments not obvious from the supplier ledger.
Maintain separate columns for original claim, reversal, reclaim and net remaining credit. Preserve the filed period and tax head for each movement.
A net annual amount can look reasonable while concealing duplicate availment or a reversal made too late. The query file should show the sequence, including the reason and legal assessment for any reclaim.
Review supplier reporting without overstating its effect
Download the relevant supplier-linked statement data and keep its generation date. Supplier corrections can change later extracts, so a current match does not erase the earlier history.
Follow up missing or incorrect supplier details using specific invoice references. Retain the supplier’s response and eventual filed evidence, rather than relying on an assurance that the accountant will fix everything.
If the query concerns the supplier’s filing or payment behaviour, obtain the records relevant to the cited requirement. Do not assume the buyer can cure every supplier-related issue merely by uploading its own bank payment.
Preserve the law applicable to the period
Have the reviewer identify the relevant eligibility, time-limit, payment and restriction provisions for the actual year and transaction. Keep the governing notification or clarification with the assessment.
A historical relaxation or certificate procedure should not be applied automatically to later periods. Equally, a later stricter process should not be treated as proof that earlier credit was always invalid.
Where interest is questioned, assess utilisation separately from availment. The credit reconciliation and the electronic-ledger history answer related but distinct questions.
Submit a concise issue-wise explanation
Group the evidence according to the notice’s allegations and identify accepted, disputed and unresolved amounts. Provide a readable summary with annexures that allow individual invoices to be checked.
Avoid claiming that all credit is valid because the total purchase expenditure is genuine. The response needs to address the particular conditions and differences raised.
Retain the filed reply, exact attachments and acknowledgement. Track any promised supplier correction and any later action required by the reviewed position.
A useful purchase-evidence pack shows the full path from acquisition to credit claim and later adjustments. That makes genuine timing differences distinguishable from duplicate claims, missing evidence and actual eligibility problems.
