The 130% super-deduction referred to above only applies to limited companies, however the Annual Investment Allowance (AIA) is available to unincorporated businesses as well as limited companies.
In the recent Autumn Statement the Chancellor announced that the AIA for expenditure on plant and machinery would become a permanent £1 million allowance.
The annual limit was originally scheduled to revert to just £200,000 from 1 January 2021 and has been extended twice to 31 March 2023. Businesses will welcome the certainty that this provides.
