A supply of a voucher for supplies up to a stated monetary value is not subject to GST. GST may still be payable on the supply for which the voucher is redeemed, and there is an increasing adjustment for unredeemed vouchers.
Note: Vouchers that do not have a stated monetary value can be subject to GST when supplied, but the price of the voucher is excluded when working out the GST on the supply for which the voucher is redeemed (see subsection 9 - 17(1)).
