From April 2023 until the end of March 2026, companies can claim 100% capital allowances on qualifying plant and machinery investments. More details can be found below and on the HMRC website.

Full Expensing (FE)

  • This replaces the super-deduction which ends on 31 March 2023, and comes into effect for three years from 1 April 2023. It is only eligible to companies and allows taxpayers to claim 100% of the cost of qualifying main/general pool expenditure from their profits.
  • It allows companies to deduct the 100% cost against profits in the tax return for the financial period expenditure.
  • It is claimable in respect of expenditure qualifying as main/special rate pool only.
  • If a company is paying the new tax rate of 25% this will result in a saving of 25p for every £1 spent (or 19p for every £1 spent for companies with profits under £50,000).

The 50% first-year allowance (FYA)

  • It is only eligible to companies in respect of qualifying expenditures classed as special rate assets. Taxpayers can deduct 50% of the cost from their profits before tax in the year of purchase.
  • After the 50% deduction in the first year, the remaining 50% balance will then be written down as writing down allowances at the current annual rate of 6%.

Annual Investment Allowance (AIA)

  • The Annual Investment Allowance (AIA) remains, providing 100% first year relief for plant and machinery investments up to £1 million. This is available for all businesses including unincorporated businesses and most partnerships.


  • If a company sells an asset on which it has claimed either full expensing or the 50% first-year allowance, there are special disposal rules which apply.
  • For the disposal of an asset on which a company has claimed full expensing, the company will be required to bring in an immediate balancing charge equal to 100% of the disposal value.
  • For the disposal of an asset on which a company has claimed the 50% first-year allowance, the company will be required to bring in a balancing charge equal to 50% of the disposal value. The remaining balance of 50% is treated in the normal way so is deducted from the special rate pool balance.
