GST Rule 37 ITC Reversal for Non-Payment to Vendors: Return, ITC and Notice Checklist
GST ITC is not safe just because the invoice is valid and appears in GSTR-2B. If vendor payment is not made within the specified period, Rule 37 can require reversal/payment of the ITC linked to the unpaid amount.
For the connected rule, example or next step, see GST on Employee Recoveries and Notice Pay: Return, ITC and Notice Checklist.
The Official ITC Test: Start With Section 16
GST input tax credit is not an automatic reimbursement of every GST-charged bill. Section 16 of the CGST Act allows a registered person to take credit of input tax on goods or services used, or intended to be used, in the course or furtherance of business, subject to conditions and restrictions. The practical checklist therefore starts with business use, valid tax invoice/debit note, receipt of goods or services, supplier reporting in outward supplies so it is communicated to the recipient, tax payment to Government and return filing.
For the connected rule, example or next step, see GST for Advertising Agencies and Media Buying: Return, ITC and Notice Checklist.
| ITC gate | What to verify | Evidence to keep |
|---|---|---|
| Business use | Expense is used or intended for business | PO, contract, campaign brief, asset register, cost centre approval. |
| Document | Invoice/debit note or other prescribed document exists | Tax invoice with supplier GSTIN, recipient GSTIN, tax, value and place-of-supply details where relevant. |
| Receipt | Goods/services have been received | GRN, service acceptance, delivery proof, project completion note. |
| Supplier reporting | Invoice appears/communicates through GST system, especially GSTR-2B control | GSTR-2B extract and vendor follow-up trail. |
| Restrictions | Section 17 blocked-credit and apportionment rules do not deny/restrict credit | Blocked-credit review checklist and reversal working. |
The 180-Day Vendor Payment Rule
The second proviso to Section 16(2), read with Rule 37, addresses cases where a recipient has availed ITC but fails to pay the supplier the value of supply along with tax within 180 days from the invoice date. Rule 37 requires reversal/payment of ITC proportionate to the amount not paid, along with interest mechanics, while furnishing the return for the tax period immediately following the 180-day period. If payment is later made to the supplier, the credit can be re-availed as per the rule framework.
For the connected rule, example or next step, see Under-Construction Property GST: Invoice and Rate Evidence Checklist.
| Situation | Rule 37 impact | Finance control |
|---|---|---|
| Invoice fully paid within 180 days | No Rule 37 reversal on payment timing | Keep payment proof mapped to invoice. |
| Invoice partly unpaid | Proportionate ITC linked to unpaid amount needs review | Maintain unpaid ageing with GST amount. |
| Supplier paid after reversal | Credit may be re-availed after payment | Track reversal and re-availment separately. |
| RCM supplies | Rule 37 excludes supplies on which tax is payable under reverse charge | Tag RCM separately in AP ageing. |
| Deemed additions under Section 15(2)(b) | Certain added amounts are deemed paid for Rule 37 purpose | Review with contract and valuation working. |
