CG71000 | Leases: grant of lease out of a short lease: introduction
From HM Revenue & Customs · Capital Gains Manual
Where a short lease, that is a lease for a term of not more than 50 years, is granted out of a short lease, a number of special rules apply.
The part disposal formula in TCGA92/S42 does not apply, see CG71001.
The full amount of any premium is taken as the consideration for CGT purposes, even though part of that premium will be chargeable as property income. A deduction for the amount chargeable as property income is then made after calculating the gain, see CG71004. However, this deduction cannot turn a gain into a loss, nor can it increase the amount of a loss.*
The allowable expenditure is reduced if the rent payable under the sub-lease is greater than the rent payable under the original lease, see CG71007.
Where only part of the land is sub-let, the allowable expenditure is reduced, see CG71012.
In certain circumstances, the capital loss arising on the grant of a sub-lease is reduced, see CG71016.
Note * - For companies the deduction is taken after indexation is deducted. Again the deduction cannot create or augment a loss.
