CG76780 | Wasting assets: computation: using the T(2) formula
From HM Revenue & Customs · Capital Gains Manual
TCGA92/S46
This instruction shows you how to use the T(2) formula to decide how much allowable enhancement expenditure has been written off. You work through the steps in number order:
What is the length of time between acquisition and disposal?
Call this T(1)
What is the length of time between enhancement and disposal?
Call this T(2)
Calculate (T(1) – T(2))
What is the predictable life of the asset from the time of the acquisition?
Call this L
Calculate L – (T(1) – T(2))
What is the allowable enhancement expenditure?
Call this E(2)
How much is the reduction in allowable expenditure, E(2), up to the date of disposal?
Calculate E(2) x T(2)/(L – (T(1) – T(2))
Call this R(2)
How much enhancement expenditure is allowable in computing the gain or loss on disposal?
Calculate (E(2) – R(2))
