Capital Allowances Act 2001 section 270EA

Proportionate adjustment in certain cases

Section 270EA requires the structures and buildings allowance to be adjusted proportionately where the chargeable period is not a full year, or where entitlement does not apply for the entire period.

• Where a chargeable period is longer or shorter than one year, the structures and buildings allowance is proportionately increased or reduced accordingly
• If the qualifying conditions (having a relevant interest and the building being in qualifying use) are met on only some days during the chargeable period, the allowance is proportionately reduced
• If the allowance period expires part way through a chargeable period, the allowance is proportionately reduced for that final period
• If entitlement to the allowance ceases during a chargeable period (for example, because the building is demolished), the allowance is also proportionately reduced
