“(1) Where goods or services are supplied for a consideration in money and on terms allowing a discount for prompt payment, the consideration shall be taken for the purposes of section 19 as reduced by the discount, whether or not payment is made in accordance with those terms. (2) This paragraph does not apply where the terms include any provision for payment by instalments.”
“Para 4(1) means what it says, namely that where goods or services are supplied on terms allowing a discount for prompt payment, consideration is deemed to be reduced by the amount of the discount, whether or not the customer obtains the discount as the result of paying promptly … [and] it is not possible to construe Para 4(1) so that it is consistent with the PVD, because to do so would go entirely against the grain of the provision, and would ‘cross the boundary between interpretation and amendment’.”
“(1) In relation to services billed in advance, there were no terms ‘allowing a discount for prompt payment’. This was because the contract was only varied (so that the customer paid a lower amount for a particular month) if the customer accepted the SPD offer for that particular month by making the payment within 24 hours. The variation of the terms happened simultaneously with the payment, and there was no term allowing for a discounted payment to be made on a future date. (2) In relation to services billed in arrears, the SPD was an offer by TalkTalk to accept a lower sum with an earlier payment date to discharge a pre-existing contractual obligation, and was thus a post-supply rebate of the consideration already due. Again, Para 4(1) did not apply.”
“Article 62 For the purposes of this Directive: (1) ‘chargeable event’ shall mean the occurrence by virtue of which the legal conditions necessary for VAT to become chargeable are fulfilled; (2) VAT shall become ‘chargeable’ when the tax authority becomes entitled under the law, at a given moment, to claim the tax from the person liable to pay, even though the time of payment may be deferred. Article 63 The chargeable event shall occur and VAT shall become chargeable when the goods or the services are supplied. … Article 65 Where a payment is to be made on account before the goods or services are supplied, VAT shall become chargeable on receipt of the payment and on the amount received. Article 66 By way of derogation from Articles 63, 64 and 65, Member States may provide that VAT is to become chargeable, in respect of certain transactions or certain categories of taxable person at one of the following times: … (b) no later than the time the payment is received; … Article 73 In respect of the supply of goods or services ... the taxable amount shall include everything which constitutes consideration obtained or to be obtained by the supplier, in return for the supply, from the customer or a third party, including subsidies directly linked to the price of the supply. … Article 79 The taxable amount shall not include the following factors: (a) price reductions by way of discount for early payment; (b) price discounts and rebates granted to the customer and obtained by him at the time of the supply; … Article 90 “(1) ... where the price is reduced after the supply takes place, the taxable amount shall be reduced accordingly under conditions which shall be determined by the Member States. …”
“…where services … are supplied for a period for a consideration the whole or part of which is determined or payable periodically or from time to time, they shall be treated as separately and successively supplied at the earlier of the following times— (a) each time that a payment in respect of the supplies is received by the supplier, or (b) each time that the supplier issues a VAT invoice relating to the supplies.” (a) each time that a payment in respect of the supplies is received by the supplier, or (b) each time that the supplier issues a VAT invoice relating to the supplies.”
