Capital allowances for vans
A van with zero CO2 emissions is eligible for a 100% first year allowance if purchased before April 2021.
Any other van should be treated as plant and machinery and allocated to the main pool, where it will be eligible for writing down allowances at 18%.
Annual Investment Allowance
The Annual Investment Allowance of £200,000 will increase to £1,000,000 for expenditure in the period 1st January 2019 to 31st December 2020 (Finance Bill 2018-19). This measure has been extended for twelve months to 31st December 2021.
Where qualifying expenditure exceeds the annual cap, tax relief will be given under the normal capital allowance regime via the main or special rate pools, with writing down allowances being given at the appropriate rates.
