911Double taxation arrangements: deduction at treaty rateU.K.
(1)This section applies if—
(a)a company pays a royalty from which it is required to deduct a sum representing income tax under Chapter 6 or 7,
(b)the income tax in respect of the payment is collectible under Chapter 15 or 16, and
(c)the company reasonably believes that, at the time the payment is made, the payee is entitled to relief in respect of the payment under double taxation arrangements.
(2)The company may calculate the sum to be deducted from the payment under Chapter 6 or 7 by reference to the treaty rate.
(3)But, if the payee is not at the time entitled to such relief, this Part has effect as if subsection (2) had never applied in relation to the payment.
(4)In this section “the treaty rate” means the rate of income tax appropriate to the payee under the arrangements.
