# Time of Supply of Vouchers (Section 12(4) / 13(4))
A voucher is an instrument that creates an obligation to accept it as consideration for a supply.
## The Two-Test Rule
| Situation | TOS |
|---|---|
| Supply identifiable at the time of issue of voucher (e.g., KFC meal voucher — known goods, known GST rate) | Date of ISSUE of voucher |
| Supply NOT identifiable at issue (e.g., generic ₹500 gift card usable across multiple stores/products) | Date of REDEMPTION of voucher |
## Why the Distinction
If at the time of issue the GST rate, place of supply, and nature of supply are all knowable, the GST liability can crystallize at issue. Otherwise, the law waits until the voucher is actually redeemed for a specific supply.
## Applies Equally to Goods and Services
The identical rule appears in Section 12(4) for goods-based vouchers and Section 13(4) for services-based vouchers.
