1. Mandatory Conditions to Claim ITC
A registered person, including an Input Service Distributor (ISD), is eligible to claim ITC only when the following four primary conditions are fulfilled:
a) Possession of Valid Tax Invoice or Debit Note
The taxpayer must hold a valid Tax Invoice or Debit Note issued by a registered supplier of goods or services. The invoice should be compliant with GST rules, including:
- Name, address, and GSTIN of the supplier
- Invoice number and date
- Name, address, and GSTIN (if registered) of the recipient
- HSN/SAC code of goods/services
- Description, quantity, and value of goods/services
- Amount of tax charged (CGST/SGST/IGST)
Note: In case of missing or mismatched invoices, ITC may be denied or reversed.
b) Receipt of Goods or Services or Both
The recipient must have actually received the goods or services. In case of goods received in lots or installments, ITC can be claimed only upon receipt of the last lot.
c) Tax Must Be Paid by the Supplier to the Government
The GST charged by the supplier must have been paid to the government, either through:
- Cash payment, or
- Input tax credit available to the supplier under Section 41 of the GST Act.
This ensures the ITC claimed is backed by actual tax remittance.
d) Filing of GST Returns
The claimant must have filed valid GST returns under Section 39 of the GST Act (i.e., GSTR-3B monthly or quarterly, as applicable). ITC can only be claimed after the return for the relevant period has been filed.
