Monthly reconciliation frequently reveals documents reported by vendors that your purchase team has not recorded. A supplier invoice in GSTR 2B not in books usually stems from three operational causes: goods in transit dispatched late in the month, an invoice misplaced before reaching accounts payable, or an erroneous filing where a vendor quoted your GSTIN for someone else's order. To understand your end-to-end reconciliation flow, refer to our GSTR-2B reconciliation and ITC matching guide.
Why an invoice in GSTR-2B cannot be claimed without book entry
A vendor filing their Form GSTR-1 satisfies the condition under Section 16(2)(aa) of the CGST Act, causing the invoice to auto-populate in your GSTR-2B. However, Section 16(2)(b) of the CGST Act explicitly bars any registered person from taking credit unless the goods or services have been received.
Where goods are delivered in lots or instalments, the first proviso to Section 16(2) of the CGST Act specifies that credit may only be taken upon receipt of the last lot or instalment. Taking credit simply because an entry sits in GSTR-2B, without a corresponding goods receipt note or invoice verification in your accounting system, creates an ineligible credit claim vulnerable to audit notices.
Common mistake: Claiming net GSTR-2B values directly without knocking off missing inward invoices leads to interest liabilities if tax authorities demand proof of physical delivery during scrutiny.
Reporting temporary reversals in Form GSTR-3B
Under CBIC Circular No. 170/02/2022-GST and the GSTN user guide on Form GSTR-3B, taxpayers must account for gross auto-populated credit and make systematic reversals rather than manually reducing Table 4A(5):
- Gross credit entry: Allow the auto-populated amount from GSTR-2B to reflect in Table 4A(5) of Form GSTR-3B.
- Temporary reversal: Report the tax component of the unbooked or in-transit invoice in Table 4B(2) under Others (reclaimable). Table 4B(1) is strictly reserved for permanent reversals under Section 17(5) and Rules 38, 42, and 43.
- Net eligible credit: Table 4C calculates net ITC as Table 4A minus the sum of Table 4B(1) and Table 4B(2).
- Reclaim in future month: In the subsequent tax period when the goods arrive and accounts payable books the invoice, include the tax in Table 4A(5) and disclose it in Table 4D(1) as reclaimed credit.
Accounting entries for missing 2B invoices
To keep statutory filings aligned with financial statements, accountants use a clearing account often designated as GST Input Tax Credit Clearing or Unclaimed ITC on Goods in Transit.

When the goods and tax invoice are physically received and entered in the purchase register next month:
Worked calculation: tracking and reclaiming unbooked invoices
Consider Mehta Engineering Private Limited reconciling its purchase records for September 2026. The monthly GSTR-2B reflects eligible credit of ₹1,62,000 across multiple invoices. During internal verification, the accountant discovers invoice INV-882 from a supplier for ₹1,00,000 plus 18% GST (₹18,000 IGST) is not in the purchase register because the material is in transit.
| Invoice number | Supplier GSTIN | Status in books | GSTR-2B IGST | GSTR-3B Table | Action taken |
|---|---|---|---|---|---|
| INV-880 | 27AAACM1234A1Z1 | Booked (goods received) | ₹90,000 | Table 4A(5) | Claimed in September 2026 |
| INV-881 | 27AAACM1234A1Z1 | Booked (goods received) | ₹54,000 | Table 4A(5) | Claimed in September 2026 |
| INV-882 | 24AAACR5678B1Z2 | Missing in books (transit) | ₹18,000 | Table 4B(2) | Reversed temporarily in September |
| Total September | All suppliers | Reconciled | ₹1,62,000 | Table 4C | Net ITC: ₹1,62,000 - ₹18,000 = ₹1,44,000 |
Calculation check for September 2026:
Gross ITC auto-populated in Table 4A(5) = ₹90,000 + ₹54,000 + ₹18,000 = ₹1,62,000.
Temporary reversal in Table 4B(2) = ₹18,000.
Net ITC availed in Table 4C = ₹1,62,000 - ₹18,000 = ₹1,44,000.
In October 2026, the consignment for INV-882 arrives and is recorded in the purchase register. In October GSTR-3B, Mehta Engineering reclaims the ₹18,000 in Table 4A(5) and reports ₹18,000 in Table 4D(1).
Vendor communication when an invoice does not belong to you
If investigation reveals that the missing invoice is not in-transit inventory but a document mistakenly uploaded by a vendor against your GSTIN, do not claim it. Request an immediate credit note or amendment in the supplier's next GSTR-1.
Frequently asked questions
Can you claim ITC if an invoice appears in GSTR-2B but the goods are still in transit?
No. Under Section 16(2)(b) of the CGST Act, you cannot take input tax credit until you have actually received the goods or services. Even though the invoice reflects in GSTR-2B, the credit must be temporarily reversed in Table 4B(2) of Form GSTR-3B until the goods physically reach your premises.
Where do you report the temporary reversal of missing book invoices in Form GSTR-3B?
The full auto-populated credit from GSTR-2B enters Table 4A(5). The credit for invoices not yet booked or goods not yet received is reversed in Table 4B(2) as a reclaimable reversal, per CBIC Circular No. 170/02/2022-GST.
How do you reclaim ITC in GSTR-3B once the missing invoice is booked?
When the invoice and goods are recorded in your purchase register in a later month, you report the tax amount in Table 4A(5) and simultaneously disclose it in Table 4D(1) of Form GSTR-3B as credit reclaimed.
