Machinery and Plant: The Functional and Premises Tests

Capital-allowance eligibility depends on what an asset does in the particular business.

Source checked · 11 October 2026 · Document date: 30 Jan 2026

Three classification questions

The guide first excludes trading stock purchased for resale. It then asks whether the item functions as apparatus used to carry on the business and whether it is instead the premises or part of the premises. Commercial desirability alone does not satisfy the functional test. The same type of object may qualify in one business but fail in another because its operational role differs. The Sixth Schedule’s working life becomes relevant only after the item qualifies as machinery or plant.

Buildings, fittings and qualifying cost

Purpose-built structures still face the premises test, although a structure performing an active operational function may have a different result. Permanence, attachment and separate identity are relevant when distinguishing a fitting from the building itself. Qualifying expenditure can include delivery, installation and directly connected professional costs. Where direct allocation is impracticable, the guide describes reasonable apportionment supported by a demonstrated connection. Its lists are illustrative, not a guarantee for every asset sharing the same name.
