# Time of Supply of Vouchers
A voucher is an instrument that the recipient can use as consideration (wholly or partly) for a future supply of goods or services. The time of supply (ToS) rule for vouchers depends on whether the underlying supply is identifiable at the time of issue.
## The Two-Case Rule
| Situation | Time of Supply |
|---|---|
| Supply is identifiable at the time of issue of voucher (e.g., a KFC voucher redeemable only at KFC for food) | Date of issue of the voucher |
| Supply is NOT identifiable at the time of issue (e.g., a general gift card usable at many merchants) | Date of redemption of the voucher |
## Why the distinction matters
- When the supply is identifiable, the nature of the goods/services, the rate of tax, and the supplier are all known up front. GST can therefore be charged at the moment the voucher is issued.
- When the supply is not identifiable, the rate of tax and even the supplier may differ depending on what the holder ultimately buys. Tax must therefore wait until the voucher is actually redeemed.
## Key trigger words
- Identifiable → issue date
- Not identifiable / general purpose → redemption date
