Between the 14th and the 20th of each month, accounts teams across India balance their purchase register against GSTR-2B. One frequent dilemma involves old invoices found during annual audit or vendor reconciliations. When an invoice from a previous financial year surfaces after November, businesses immediately ask whether that lapsed credit can still be claimed or reclaimed in Form GSTR-3B.
The answer depends entirely on whether the credit was never claimed in the first place, or whether it was claimed on time and then temporarily reversed. Conflating these two concepts leads either to lost working capital or to heavy scrutiny notices under Form GST DRC-01C.
Fresh ITC claims versus re-availing reversed ITC
GST law draws a strict legal distinction between taking input tax credit for the first time and re-availing credit that was already taken and subsequently reversed. Conflating these two categories creates confusion around the ITC reclaim lapsed time limit.
Under Section 16(4) of the CGST Act, a registered person is not entitled to take input tax credit in respect of any invoice or debit note after the 30th day of November following the end of the financial year to which the invoice pertains, or the date of filing the annual return, whichever is earlier. For detailed reconciliation steps around the annual cutoff, refer to our guide on Section 16(4) ITC time limit reconciliation.
If an invoice dated 10 August 2024 was never reported in any GSTR-3B up to the return for October 2025 (filed in November 2025), the credit has legally lapsed. There is no mechanism in GST law to reclaim an unavailed, lapsed original invoice once the Section 16(4) cutoff passes. That unavailed tax amount must be charged to the profit and loss account as an irrecoverable expense.
By contrast, re-availing a previously reversed credit operates under a completely different statutory route. When credit was claimed within the statutory deadline and subsequently reversed under temporary statutory rules, re-availing that credit upon fulfilling payment conditions is not considered a fresh claim under Section 16(4).
The statutory exemption under Rule 37(4)
The primary exception to the annual November deadline is explicitly codified in Rule 37(4) of the CGST Rules:
“The time limit specified in sub-section (4) of section 16 shall not apply to a claim for re-availing of any credit, in accordance with the provisions of the Act or the provisions of this Chapter, that had been reversed earlier.” Rule 37(4), CGST Rules
This provision directly connects with the second and third provisos to Section 16(2) of the CGST Act. The second proviso mandates that if a recipient fails to pay the supplier the value of supply plus tax within 180 days from the invoice date, an amount equal to the ITC availed must be paid along with interest under Section 50. The third proviso gives the recipient the absolute right to re-avail the credit once payment is made to the supplier:
“Provided also that the recipient shall be entitled to avail of the credit of input tax on payment made by him to the supplier of the amount towards the value of supply of goods or services or both along with tax payable thereon.” Section 16(2) third proviso, CGST Act
Because Rule 37(4) explicitly removes Section 16(4) restrictions for re-availing reversed credits, you can reclaim this credit in GSTR-3B whether the payment occurs six months, one year, or two years after the invoice date. The credit never lapses as long as the initial claim occurred within the valid Section 16(4) window.
Partial payments allow partial reclaims: If you settle 50% of the overdue invoice amount to your vendor after two years, you can re-avail exactly 50% of the reversed ITC in that month. You do not need to wait for full settlement to begin reclaiming.
Re-availing credit under Rule 37A for vendor default
Another major scenario involves Rule 37A of the CGST Rules. When you claim ITC based on an invoice visible in GSTR-2B, but your supplier fails to file their corresponding Form GSTR-3B by 30th September following the end of the financial year, you are required to reverse that ITC on or before 30th November.
Many accountants fear that reversing credit under Rule 37A on 30th November causes the credit to lapse forever. The second proviso to Rule 37A addresses this scenario directly:
“Provided further that where the said supplier subsequently furnishes the return in FORM GSTR-3B for the said tax period, the said registered person may re-avail the amount of such credit in the return in FORM GSTR-3B for a tax period thereafter.” Rule 37A second proviso, CGST Rules
Even if the defaulting vendor takes twelve months to clear their backlog and file the pending GSTR-3B, you are legally entitled to re-avail the credit in the return period immediately following their filing. The Section 16(4) time limit does not block this re-availment.
Permanent reversals that can never be reclaimed
While temporary reversals under Rule 37 and Rule 37A can be re-availed without time limits, permanent reversals can never be reclaimed. Confusing temporary reversals with permanent ones creates severe exposure during department audits.
Warning on permanent reversals: Reversals under Section 17(5) for blocked credits (such as motor vehicles or food and beverages), banking reversals under Rule 38, and exempt supply apportionments under Rule 42 and Rule 43 are permanent. Attempting to reclaim credits previously reversed under these provisions will trigger recovery proceedings with interest and penalties.
| Category of reversal | Governing rule or section | Original GSTR-3B table | Can you reclaim after 30th November? |
|---|---|---|---|
| 180-day non-payment | Section 16(2) and Rule 37 | Table 4(B)(2) | Yes, whenever payment is made to vendor |
| Supplier non-filing of 3B | Rule 37A | Table 4(B)(2) | Yes, once supplier files the return |
| Goods not received in period | Section 16(2)(b) | Table 4(B)(2) | Yes, when goods arrive |
| Unclaimed original invoice | Section 16(4) | Never claimed | No, credit lapses permanently |
| Blocked credit | Section 17(5) | Table 4(B)(1) | No, permanent statutory bar |
| Exempt supply ratio | Rule 42 and Rule 43 | Table 4(B)(1) | No, permanent reversal |
Reporting reclaims in Form GSTR-3B
According to the official GSTN GSTR-3B user manual, any reclaimable ITC reversed in an earlier period must be entered correctly to keep the tax ledger balanced. For a detailed breakdown of all return tables, read our guide to GSTR-3B tables and format and our step-by-step input tax credit reclaim procedure.
When you file GSTR-3B for the tax period in which the condition is fulfilled:
- Add the reclaimed amount to the auto-populated number in Table 4(A)(5) (All other ITC). This step adds the tax amount back into your electronic credit ledger.
- Enter the exact reclaimed amount in Table 4(D)(1) (ITC reclaimed which was reversed under Table 4(B)(2) in earlier tax period). This is an informational disclosure that tells the system your excess claim over GSTR-2B is a legitimate reclaim rather than an unauthorized claim.
Worked rupee example: fresh lapsed credit versus valid reclaim
Consider Om Precision Engineering, a precision parts manufacturer. During their internal audit in December 2026, the accounts team identifies two distinct vendor invoices from the previous financial year (FY 2025-26):
- Invoice A (INV-801): Dated 14 May 2025 for ₹2,00,000 plus 18% IGST of ₹36,000. Om Precision received the goods, but the invoice was misplaced and was never entered in the purchase register or claimed in GSTR-3B. The Section 16(4) deadline for FY 2025-26 expired on 30 November 2026.
- Invoice B (INV-905): Dated 20 July 2025 for ₹1,00,000 plus 18% IGST of ₹18,000. This invoice was properly claimed in the July 2025 GSTR-3B. Because of a quality dispute, payment was withheld beyond 180 days. Om Precision reversed the ₹18,000 credit in Table 4(B)(2) in their January 2026 return. In December 2026, the dispute is resolved and the full ₹1,18,000 is transferred to the vendor bank account.
| Invoice | Tax amount | Original status | Action in December 2026 | Legal justification |
|---|---|---|---|---|
| INV-801 (Fresh) | ₹36,000 | Never claimed in GSTR-3B | Cannot claim: lapsed | Section 16(4) cutoff expired on 30 Nov 2026 |
| INV-905 (Reclaim) | ₹18,000 | Reversed in Table 4(B)(2) | Reclaim in Table 4(A)(5) | Rule 37(4) exempts re-availing from Section 16(4) |
For the December 2026 return (filed in January 2027), assume Om Precision has current eligible inward credit of ₹1,50,000 auto-populated from GSTR-2B. Here is how Table 4 of GSTR-3B is prepared:
| GSTR-3B Table | Auto-populated from 2B | Final filed value | Explanation |
|---|---|---|---|
| Table 4(A)(5) | ₹1,50,000 | ₹1,68,000 | Includes ₹1,50,000 current 2B plus ₹18,000 reclaimed from INV-905 |
| Table 4(B)(2) | ₹0 | ₹0 | No temporary reversals in December 2026 |
| Table 4(C) Net ITC | ₹1,50,000 | ₹1,68,000 | Net credit credited to electronic credit ledger |
| Table 4(D)(1) | ₹0 | ₹18,000 | Discloses the exact reclaimed amount under Rule 37 |
The ₹36,000 on Invoice A is completely lost. Claiming it by adding it to Table 4(A)(5) would violate Section 16(4) and attract automated demands with interest under Section 50. Invoice B, however, is successfully reclaimed into the cash-flow cycle.
Common pitfalls during tax audits
Tax authorities routinely review Table 4(A)(5) and Table 4(D)(1) disclosures during desk reviews and audits. Keep these practical considerations in mind:
- Never omit Table 4(D)(1): If you increase Table 4(A)(5) without declaring the matching figure in Table 4(D)(1), the GST portal algorithm flags an unexplained mismatch against GSTR-2B. This generates an automated scrutiny intimation in Form GST DRC-01C.
- Maintain complete proof of reversal: When claiming a reclaim two years down the line, keep copies of the previous GSTR-3B where Table 4(B)(2) was debited, along with bank payment advice proving when the supplier was actually paid.
- Interest paid on reversal is not refundable: If you paid interest under Section 50 when reversing credit after 180 days, you can re-avail the principal tax amount upon settlement, but the interest paid to the government is never recoverable.

Frequently asked questions
Can you reclaim ITC if you missed claiming an invoice before the 30th November deadline?
No. Under Section 16(4) of the CGST Act, fresh input tax credit that was never claimed before the 30th November following the end of the financial year lapses permanently. You cannot take that credit in a later return.
Does the Section 16(4) deadline apply to re-claiming credit reversed under Rule 37?
No. Under Rule 37(4) of the CGST Rules, the time limit specified in Section 16(4) does not apply to a claim for re-availing any credit that had been reversed earlier upon satisfying payment conditions.
Can you reclaim credit if a supplier files GSTR-3B after a Rule 37A reversal?
Yes. The second proviso to Rule 37A allows the recipient to re-avail the reversed input tax credit in GSTR-3B for any subsequent tax period once the supplier furnishes their GSTR-3B.
Where do you enter reclaimed credit in Form GSTR-3B?
You add the reclaimed amount into Table 4(A)(5) alongside current eligible credit and report the same reclaimed amount in Table 4(D)(1) as a disclosure.
