Commentary on Sections Glossary Background Section 7: No double allowances
63.This section is based on part of section 147(1) and (2) of CAA 1990. It prevents allowances from being claimed under one Part if an allowance has been made under another Part in respect of the same capital expenditure.
64.Subsection (1)(b) extends this and prevents allowances from being claimed under different Parts in respect of expenditure on the same asset.
65.Before this Act, patents and know-how allowances were dealt with in ICTA rather than CAA 1990. As a result, they are not covered by section 147 of CAA 1990. Subsection (2) replicates this exclusion by excluding Parts 7 and 8 from the rule in this section. In practice, however, this is likely to be of little effect since it is extremely unlikely (even if possible) that expenditure qualifying for allowances under either of these Parts would also qualify for allowances under any other Part. See Note 6 in Annex 2.
