Formula
where—
V is the value of the net benefit to the charity at, or immediately after, the time when the disposal is made, whichever is less,
IC is the amount of the incidental costs of making the disposal to the individual making it, and
B is the total value of any benefits received in consequence of making the disposal by the individual making the disposal or a person connected with the individual.
(2)If the disposal is at an undervalue, the relievable amount is given by the formula—
Formula
where—
E is the amount (if any) by which V (as defined in subsection (1)) exceeds the amount or value of the consideration for the disposal,
C is given by subsection (4), and
B is as defined in subsection (1).
(3)But if the amount given by the formula in subsection (1) or (2) is a negative amount, the relievable amount is nil.
(4)C is found by taking the following steps.Step 1Calculate the consideration for which the disposal is treated as made for the purposes of TCGA 1992 as a result of section 257(2)(a) of that Act (in case of disposal to charity etc, consideration to be such that no gain or loss accrues).Step 2Find the excess (if any) of the amount calculated at Step 1 over the amount or value of the consideration for the disposal.If there is such an excess, C is the amount of that excess or, if less, the amount of the incidental costs of making the disposal to the individual making it.If there is no such excess, C is nil.
(5)This section needs to be read with—
(a)section 435 (incidental costs of making disposal),
(b)section 436 (consideration), and
(c)sections 437 to 440 (value of net benefit to charity).
