Commentary on Sections Glossary Structure of Part 2 Section 46: General exclusions applying to sections 40, 44 and 45
232.This section brings together legislation in sections 22(6B) and (6C), 38, 50 and 81 of CAA 1990. These are general exclusions which stop expenditure being first-year qualifying expenditure.
233.The exclusions mostly relate to the type of plant or machinery bought or its use. Two which do not are worth noting:
	General exclusion 1 excludes from first-year qualifying expenditure any qualifying expenditure in the chargeable period in which there is a permanent discontinuance of a qualifying activity. This expenditure is fully relieved by a balancing allowance (or reduction in balancing charge) for the appropriate pool. Cutting out first-year allowances simplifies the route to tax relief; and
	General exclusion 8 excludes from first-year qualifying expenditure any qualifying expenditure a person is treated as incurring if they bring into use plant or machinery:previously not used for that qualifying activity; orreceived as a gift.
First-year allowances may already have been given for this plant or machinery when it was originally bought.  But an exception to this is made for certain pre-trading expenditure on mineral exploration and access if a person is treated as having sold and bought plant or machinery.
234.It might be thought that the reference in general exclusion 7 to a “trade or business” should be to a “qualifying activity or business”. However, in the context of section 22(6C) of CAA 1990 from which this comes, the phrase “trade or business” translates into this Act so as to make neither wider nor narrower the scope of this exclusion. See Note 14 in Annex 2.
