Revenue Note for Guidance
The purpose of section 287 is to enable the amount of the wear and tear allowance to be made for a chargeable period in respect of machinery or plant to be determined on the basis of the true written-down value of the machinery or plant. Thus, the section applies for the purposes of calculating the written-down value at the commencement of the chargeable period of motor vehicles (section 284(3)) and applying the overall limit on the amount of wear and tear allowances that may be made in respect of machinery or plant generally (section 284(4)). For those purposes, normal wear and tear allowances are deemed to have been made in respect of machinery or plant used during any chargeable period in circumstances in which it attracted no wear and tear allowance or a restricted wear and tear allowance. An example of the use of machinery or plant in such circumstances is where a motor vehicle is bought for trade purposes but in a chargeable period is used entirely or partly for private purposes.
(1) “wear and tear allowance” is an allowance made under section 284 apart from any increase (free depreciation) in that allowance under section 285.
“normal wear and tear allowance” is defined as the wear and tear allowance or greater wear and tear allowance, if any, that would have been made for the chargeable period if the conditions specified in subsection (3) had been fulfilled in relation to that chargeable period. The reference to greater wear and tear allowance is designed to cater for the case where a restricted wear and tear allowance is given because, for example, the machinery or plant is used partly for business purposes and partly for other purposes.
(2) Where for any chargeable period no wear and tear allowance or a wear and tear allowance less than the normal wear and tear allowance is made in respect of machinery or plant used during the chargeable period, then, for certain purposes of section 284, the normal wear and tear allowance is deemed to have been made to the person concerned in respect of the machinery or plant for that chargeable period. The purposes in question are the calculation of the written-down value at the commencement of a chargeable period of motor vehicles (subsection (3) of that section refers) and the application of the overall limit on the amount of wear and tear allowances that may be made in respect of machinery or plant generally (subsection (4) of that section refers).
(3) The normal wear and tear allowance for a chargeable period is to be calculated on the basis that —
(4) Where at any time after a company acquired machinery or plant it is not within the charge to corporation tax, any year of assessment or part of a year of assessment falling within that time will be treated as a chargeable period as if it had been an accounting period of the company. Thus, a normal wear and tear allowance will be deemed to have been made in respect of machinery or plant used during any such period.
