How does the super deduction work?

In the run up to your accounting year end its important to consider how the Super Deduction Tax relief works and how this affects your business.
  • Projected capital expenditure and how capital allowances/super deduction could apply including the nature of future expenditure that could potentially qualify. 
  • Contracts and procurement; for assets acquired through framework and MSA-style contracts. 
  • Disposals can result in a balancing charge clawback for assets subject to temporary first-year allowances. This will require additions to be tracked separately from those that will be disposed of from asset pools. 

Disposing of assets that qualify for the super deduction or special rate allowance 

Subject to some exclusions, the enhanced relief is given by way of a First-Year Allowance (“FYA”) at the relevant percentage for the asset type.  The percentages are as follows:-

What assets qualify  

Examples of such asset 

130% 

"Super deduction" 

Assets that qualify for plant and machinery allowances, ordinarily at 18% 

Computer equipment, vans, office equipment 

100% 

Assets that qualify for plant and machinery allowances, used partly in a ring-fence business and partly in another qualifying business 

Computer equipment or machinery used for extracting oil & gas that are used in a ring-fence business 

50% 

“Special rate allowance” 

Assets that qualify for capital allowances at the lower rate of 6% (special rate assets) 

Solar panels electrical and lighting systems, cold water systems, lifts 

*50% of the cost can be claimed as a First Year Allowance, with the remaining 50% of the cost attracting 6% Writing Down Allowances on a reducing balance basis. 

The temporary measure has been designed to encourage capital investment in the UK.

Not all plant and machinery will qualify for this tax relief.  The exclusions are set out in the following table:-

How does this new enhanced deduction interact with the existing Annual Investment Allowance?

The annual investment allowance (“AIA”) will remain at £1m for the period from 1 January 2021 – 31 December 2021. There is no limit to expenditure to which the FYA for the period from 1 April 2021 to 31 March 2023 may apply.

The new enhanced deduction is in addition to the existing AIA therefore companies may be eligible to claim both the AIA and the new FYA. This can create an attractive cash advantage for many companies who are planning on investing in plant and machinery however careful consideration must be given to what tax relief to claim.

Companies who are planning on investing in plant and machinery of more than £1m in the next few years should consider taking advantage of the super deduction by bringing expenditure forward and incur the costs on or before 31 March 2023.

When the corporation tax rate of 25% applies from 1 April 2023, the tax deduction for expenditure qualifying for capital allowances will also be 25p for every £1 invested, but without the benefit of a first year allowance or such a generous AIA, it will be obtained over time and not in one year.
