Capital Allowances Act 2001

Section 109: Writing-down allowances at 10%

459.This section is based on sections 42(1) and (2) and 24(2)(a)(ii) of CAA 1990. It replaces the usual 25% rate of writing-down allowances by a 10% rate. This 10% rate applies to:

  • the overseas leasing pool; and

  • any single asset pool if the plant or machinery is used at any time in the designated period for overseas leasing which is not protected leasing (except for long-life assets for which the normal rate for that of 6% still applies).

460.Subsection (3) differs in some respects from section 42(2) of CAA 1990. The subsection:

  • applies the 10% rate to all single asset pools including those for expenditure on plant or machinery used partly for the purposes of the qualifying activity and partly for other purposes. These pools are not mentioned in section 42(2) of CAA 1990. See Change 20 in Annex 1;

  • does not mention special leasing. Section 42(2)(e) of CAA 1990 needs to provide for the 10% rate to apply to special leasing. But the simpler approach in section 107 (see paragraph 457 above) means the 10% rate does still apply in such cases. See Note 22 in Annex 2; and

  • covers single asset pools generally. This includes single asset pools for contributions. So it is not necessary to mention them explicitly as in section 42(2)(d) of CAA 1990. See Note 23 in Annex 2.
