Guidance

Super-deduction

A new 130% first-year capital allowance for qualifying plant and machinery assets; and a 50% first-year allowance for qualifying special rate assets.

From 1 April 2021 until 31 March 2023, companies investing in qualifying new plant and machinery assets will be able to claim:

  • a 130% super-deduction capital allowance on qualifying plant and machinery investments
  • a 50% first-year allowance for qualifying special rate assets

The super-deduction will allow companies to cut their tax bill by up to 25p for every £1 they invest, ensuring the UK capital allowances regime is amongst the world’s most competitive.

The government has offered unprecedented support for businesses during Covid. Even so, pandemic-related economic shocks and the accompanying uncertainty have chilled business investment. This super-deduction will encourage firms to invest in productivity-enhancing plant and machinery assets that will help them grow, and to make those investments now.
