Designed in part to help offset the increased Corporation Tax main rate, the Chancellor announced the introduction of a new ground-breaking 100% first-year capital allowance for qualifying plant and machinery assets. This measure is also expected to help boost business investment and growth.

The new measure, known as full expensing, will initially apply from 1 April 2023 until 31 March 2026 although the Chancellor suggested that it may be made permanent in due course. The measure builds on the success of the super-deduction which ends on 31 March 2023. Under full expensing, for every pound a company invests, their taxes will be cut by up to 25p.

To qualify for full expensing, expenditure must be incurred on the provision of “main rate” plant or machinery. It should be noted that full expensing is available to companies subject to Corporation Tax only. 

Plant and machinery that may qualify for full expensing includes (but is not limited to):

• machines such as computers, printers, lathes and planers
• office equipment such as desks and chairs
• vehicles such as vans, lorries and tractors (but not cars)
• warehousing equipment such as forklift trucks, pallet trucks, shelving and stackers
• tools such as ladders and drills
• construction equipment such as excavators, compactors, and bulldozers
• some fixtures such as kitchen and bathroom fittings and fire alarm systems in non-residential property.

For “special rate” expenditure, that doesn’t qualify for full expensing, a 50% first-year allowance (FYA) can be claimed instead. The 50% FYA was introduced alongside the super-deduction and was due to end on 31 March 2023. It will now be extended by three years to 31 March 2026.

Businesses can also continue to use the Annual Investment Allowance (AIA) to claim a 100% tax deduction on qualifying expenditure on plant and machinery of up to £1m per year. This includes unincorporated businesses and most partnerships.
