Taxation of Chargeable Gains Act 1992

1 (1) A lease of land shall not be a wasting asset until the time when its duration does not exceed 50 years. U.K.

(2) If at the beginning of the period of ownership of a lease of land it is subject to a sublease not at a rackrent and the value of the lease at the end of the duration of the sublease, estimated as at the beginning of the period of ownership, exceeds the expenditure allowable under section 38(1)(a) in computing the gain accruing on a disposal of the lease, the lease shall not be a wasting asset until the end of the duration of the sublease.

(3) In the case of a wasting asset which is a lease of land the rate at which expenditure is assumed to be written off shall, instead of being a uniform rate as provided by section 46, be a rate fixed in accordance with the Table below.

(4) Accordingly, for the purposes of the computation of the gain accruing on a disposal of a lease, and given that —

(a) the percentage derived from the Table for the duration of the lease at the beginning of the period of ownership is P(1),

(b) the percentage so derived for the duration of the lease at the time when any item of expenditure attributable to the lease under section 38(1)(b) is first reflected in the nature of the lease is P(2), and

(c) the percentage so derived for the duration of the lease at the time of the disposal is P(3), then—

(i) there shall be excluded from the expenditure attributable to the lease under section 38(1)(a) a fraction equal to —

and

(ii) there shall be excluded from any item of expenditure attributable to the lease under section 38(1)(b) a fraction equal to—

(5) This paragraph applies notwithstanding that the period of ownership of the lease is a period exceeding 50 years and, accordingly, no expenditure shall be written off under this paragraph in respect of any period earlier than the time when the lease becomes a wasting asset.

(6) Section 47 shall apply in relation to this paragraph as it applies in relation to section 46.
