Finance Act 2021
- A new Super-deduction allowance for plant & machinery on new qualifying expenditure by companies, incurred between 1 April 2021 and 31 March 2023, will receive an enhanced 130% first year allowance.
- A 50% First Year Allowance is also introduced.
- A short-term measure to prevent leases, where extended due to COVID-19, from inadvertently becoming long funding leases and falling foul of the anti-avoidances measures included in the Capital Allowances Act 2001.
- A 100% Enhanced Capital Allowance for Freeports is to be introduced, as well as a 10% Structures and Buildings Allowance. These coincide with the announcement of the eight new Freeport sites across England, one in Wales and two in Scotland (and potentially further sites across the rest of the UK).
