2018.This section deals with cases where either of the two previous sections apply to a part realisation of an intangible fixed asset. It is based on paragraph 22 of Schedule 29 to FA 2002.
2019.The section determines the appropriate proportion of the tax written-down value or cost of the asset to be set off.
2020.Subsection (2) gives a formula that covers both the simple case, where the tax written-down value has not diverged from the book value in the accounts, and the more complicated case where the tax and book values have diverged.
