Income Tax (Trading and Other Income) Act 2005

289 The additional calculation rule: special cases

(1) This section explains how section 288 operates in some special cases.

(2) If—

(a) the receipt under calculation is under any of sections 277 to 281, and

(b) the lease does not extend to the whole of the premises subject to the taxed lease,

the basic relieving amount by reference to a taxed receipt is calculated by multiplying the amount given by the formula in subsection (4) of section 288 by the fraction of those premises which is subject to the lease.

(3) This fraction is calculated on a just and reasonable basis.

(4) If the basic relieving amount given by section 288(4) or subsection (2) above by reference to a taxed receipt would otherwise exceed the unused amount of the taxed receipt, the basic relieving amount is the unused amount.

(5) If the amount of the reduction under section 288 would otherwise exceed the amount given, in respect of the receipt under calculation, by the formula in section 277, 279, 280, 281 or 282, the amount of the reduction is equal to the amount given by the formula.
