You may re-avail reversed GST input tax credit (ITC) only if the original reversal was temporary and you have met the condition tied to that reversal. The route depends on why the credit was reversed: Rule 37 concerns non-payment to the supplier within 180 days, while Rule 37A concerns a supplier that reported invoice details but did not file the corresponding GSTR-3B. CBIC’s GSTR-3B guidance generally reports the reversal in Table 4(B)(2), then the eligible reclaim in Table 4(A)(5) and also Table 4(D)(1).
First identify why the ITC was reversed
Do not treat every reversal as recoverable. Start with the rule or eligibility condition that led to the original reversal. A later event restores credit only when the applicable rule allows re-availment and the other eligibility conditions and time limits are satisfied.
CBIC distinguishes temporary reversals, which may be reclaimed after specified conditions are met, from absolute or otherwise non-reclaimable reversals. An event such as later payment to a supplier does not by itself make an ineligible or permanent reversal reclaimable. See CBIC’s Input Tax Credit Rules and Circular No. 170/02/2022-GST.
Rule 37: reclaim after paying the supplier
Rule 37 applies when a recipient has taken ITC on an inward supply but does not pay the supplier the value of the supply plus tax within 180 days from the invoice date, as referred to in the second proviso to section 16(2) of the CGST Act. The reversal is proportionate to the amount left unpaid; if only part of the invoice remains unpaid, the reversal is not automatically the full invoice credit. The rule also provides for adding the amount to output tax liability and addresses interest.

If you later pay the supplier the value and tax, Rule 37 permits you to re-avail the corresponding credit in a return, subject to the applicable eligibility requirements and time limits. Reconcile the original invoice credit, the amount unpaid, the proportion reversed, the later payment, and the amount you intend to reclaim. Keep records that support this reconciliation; this is practical recordkeeping, not a claim that one universal document checklist is prescribed for every case.
Rule 37A: reclaim after the supplier files GSTR-3B
Rule 37A is a different situation; it is not a payment-to-supplier rule. It concerns an invoice or debit note whose details the supplier furnished in GSTR-1 or through the Invoice Furnishing Facility (IFF), where the supplier had not furnished the corresponding GSTR-3B by 30 September following the end of the financial year in which you availed the credit.

In that circumstance, the recipient must reverse the credit in GSTR-3B on or before 30 November following that financial year. If the recipient misses that reversal deadline, the notification says the amount is payable with interest under section 50. If the supplier subsequently furnishes the corresponding GSTR-3B, the recipient may re-avail the amount in a GSTR-3B for a later tax period. These dates and conditions come from Rule 37A, inserted by Notification No. 26/2022-Central Tax dated 21 December 2022. Verify the current rule for the relevant financial year before filing.
Rule 37 and Rule 37A are not interchangeable
| Issue | Rule 37 | Rule 37A |
|---|---|---|
| Reason for reversal | Supplier consideration, including tax, was not paid within 180 days from the invoice date. | Supplier reported invoice or debit-note details in GSTR-1 or through IFF but did not file the corresponding GSTR-3B by the specified September checkpoint. |
| Condition for re-availment | Pay the supplier the value and tax; re-availment remains subject to other applicable requirements. | The supplier subsequently files the corresponding GSTR-3B; re-availment is in a later tax period. |
| Key timing | 180 days from the invoice date for the payment condition. | Check supplier filing by 30 September and recipient reversal by 30 November following the relevant financial year, as Rule 37A specifies. |
| GSTR-3B disclosure | For a conditionally reclaimable reversal, CBIC’s Circular 170 guidance applies: reversal in Table 4(B)(2), then reclaim in Table 4(A)(5) and also Table 4(D)(1). | For a conditionally reclaimable reversal, CBIC’s Circular 170 guidance applies: reversal in Table 4(B)(2), then reclaim in Table 4(A)(5) and also Table 4(D)(1). |
How to report reversal and reclaim in GSTR-3B
CBIC Circular 170/02/2022-GST, dated 6 July 2022, explains the reporting treatment for temporary reversals and subsequent reclaims:

- At reversal: Report a conditionally reclaimable reversal in Table 4(B)(2).
- When the condition is met: Report eligible reclaimed ITC in Table 4(A)(5), and also disclose all such reclaimed ITC in Table 4(D)(1).
- Check the net figure: Table 4(C), net ITC available, is calculated as Table 4(A) minus Tables 4(B)(1) and 4(B)(2).
Do not enter a reclaim only in Table 4(D)(1): CBIC’s guidance says the reclaim also belongs in Table 4(A)(5). Nor should a reclaim be presented as new ITC on an additional invoice; it is the restoration of eligible credit reversed earlier. Circular 170 describes Table 4(B)(1) for absolute or non-reclaimable reversals and ineligible ITC, including examples under Rules 38, 42 and 43 and section 17(5). The portal interface and validations can change, so check current return instructions when filing.

Before you file
- Confirm the legal reason for the original reversal and whether it is reclaimable.
- For Rule 37, verify the unpaid amount, the proportion reversed, and evidence of subsequent payment of the value and tax.
- For Rule 37A, verify the supplier’s invoice reporting, the corresponding GSTR-3B filing status, and the relevant financial-year deadlines.
- Reconcile the original reversal with the amount being re-availed so the reclaim does not exceed the credit eligible under the applicable rule.
- Check current law, return instructions, and portal validations for the relevant tax period. For disputed or fact-specific claims, consult a qualified GST professional.
