They provide a de minimis limit. Expenditure is not usually long-life asset expenditure if a person’s total expenditure on long-life assets is less than £100,000 a year. If the limit is exceeded all the relevant expenditure is long-life asset expenditure. 425 Section 98 means the limit is available to: individuals and partnerships within subsections (1) and (2); and any company, for the purposes of corporation tax. 426 There is a minor change in section 98(1)(a). It refers to any qualifying activity carried on by an individual. Section 38C(3)(a) of CAA 1990 only refers to trades and professions. See Change 19 in Annex 1. 427 Section 99 gives the £100,000 limit. It also: increases or reduces the limit if a chargeable period is more or less than a year; and reduces the limit if a company has associated companies. This reduction is done in the same way that the limit for small companies relief is reduced in section 13 of ICTA. 428 Section 100 sets out when the limit is exceeded. It also provides that all the expenditure on an item of plant or machinery is looked at to see if the limit is exceeded – not just the expenditure which is incurred (or treated as incurred) in a particular chargeable period.
