434R11. For the purpose of determining any amount under sections 434R0.1 to 434R12, other than an amount of net tax that is required by those sections to be determined in accordance with section 428 of the Act, the following rules apply:(1) where, at any time, a supplier accepts, as full or partial consideration for the supply of a property or a service, a coupon, ticket or other voucher — referred to in this paragraph as a “coupon” — other than a gift certificate, that may be exchanged for the property or the service or that entitles the recipient of the supply to a reduction or rebate on the price of the property or service and where the supplier is entitled to receive from another person an amount by reason of the redemption of the coupon, the coupon is deemed to be the consideration for the supply and the tax computed on that consideration is deemed to become collectible and to have been collected at that time;
(2) where the consideration for a supply indicated on the invoice in respect of the supply may be reduced if it is paid within the time limit specified thereon and where it is so reduced, the consideration for the supply is deemed to be equal to the amount of the consideration so reduced and the total tax collected or collectible in respect of the supply is deemed to be equal to the tax computed on that amount; and
(3) if consideration, or a part of it, for a taxable supply, other than a supply by way of sale of an immovable, made by a supplier in the course of activities engaged in by the supplier in a division or branch of the supplier becomes due, or is paid without having become due, to the supplier at a time when the division or branch is a small supplier division within the meaning of section 337.2 of the Act, that consideration or part, as the case may be, is deemed not to be consideration for a taxable supply; and
(4) if property or a service is acquired by a person for consumption, use or supply in the course of activities engaged in by the person in a division or branch of the person and, at a time when the division or branch is a small supplier division, within the meaning of section 337.2 of the Act, an amount becomes due, or is paid without having become due, by the person for the supply of the property or service to the person, the amount shall not be included in determining the purchase threshold under section 434R8.3 for any fiscal year of the person.
