Section 421: The amount of the income: the basic amount
1268.This section gives the formula (PM – TWDV) for determining the basic amount of income of the partnership which is then to be adjusted in accordance with section 422 or 423 to determine the amount of income of the company for the purposes of section 417 on any day (“the relevant day”). It is based on paragraph 29 of Schedule 10 to FA 2006.
1269.Subsection (4) applies the definition of PM in section 400 with modifications.
1270.Subsection (5) determines the amount which is TWDV.
1271.The TWDV amount is made up of the unrelieved qualifying expenditure in all single asset pools, class pools and the main pool. This is the amount that would be carried forward assuming that a chargeable period ends on the relevant day and a new one begins on the following day (see subsection (6)(a)).
1272.But any expenditure on the acquisition of plant or machinery on the relevant day is excluded, except for plant or machinery acquired from qualifying companies (see subsection (6)(b)). This adjustment ensures that amounts in respect of plant or machinery acquired from qualifying companies (as defined in subsection (7)) on the relevant day are included in both the PM and the TWDV amounts.
