Mark Moore, Tax Partner, explains the new Super Deduction…





What is the Super Deduction?

In the budget earlier this month, the government announced a new Capital Allowance ‘The Super Deduction’ to promote business investment and productivity. A Capital Allowance is an allowance which can be claimed on capital equipment employed within your business and provides a direct tax relief based on the original cost or an annual allowance based on depreciated cost.

Since the Covid-19 pandemic, already low levels of business investment have fallen further and so the super deduction aims to provide a more generous tax break to stimulate business growth. This will obviously be countered by the proposed increase in Corporation tax rates from 2023, but in the meantime this estimated £25bn tax break is designed to be a strong incentive to make additional investments and bring already planned investments forward and will provide up to 25p off company tax bills for every £1 of qualifying spend.


How does it work?

For qualifying main rate plant and machinery investments from 1 April 2021 until 31 March 2023, a 130% first year relief can be claimed.

This will be a super deduction of 130% of the expenditure incurred on the purchase of most business equipment, i.e. on a spend of £100K, the corporate tax deduction will be £130K giving direct corporation tax relief at 19% on £130K which is £24,700.

Usually, this expenditure would fall within the Annual Investment Allowance which would provide direct tax relief of £19K otherwise the relief would be restricted to a maximum of 18% of the depreciated cost each year.

There is also a reduced “Super Deduction” of 50% for assets that are classed as “special rate” for Capital Allowances. These are generally long life assets and for which currently an annual allowance of 6% only is usually available.


What kind of equipment is eligible?

Most capital assets used in the course of a business are considered eligible for claiming capital allowances. The following list includes some but not all the types of assets that qualify for the super-deduction.

  • Solar panels
  • Computer equipment and servers
  • Tractors, lorries, vans
  • Ladders, drills, cranes
  • Office chairs and desks
  • Electric vehicle charge points
  • Refrigeration units
  • Compressors
  • Foundry equipment


You can find see the full factsheet and find out more about the eligibility of different types of investments for different types of capital allowances.


Can I use the super-deduction to buy used equipment?

No, unlike the Annual Investment Allowance, the super-deduction relief excludes the purchase of used equipment.


Eligibility – Who can claim?

Companies within the charge to Corporation Tax who invest in plant and machinery on or after 1 April 2021. The Super Deduction is unfortunately not available to sole traders, partnerships or LLPs. However, these businesses can still claim the Annual Investment Allowance which provides 100% relief on business capital investment of up to £1M until 31 December 2021.
