Capital Allowances Act 2001 section 333

Writing off initial allowances

Section 333 establishes when an initial allowance granted in respect of qualifying expenditure is written off for capital allowances purposes.

• An initial allowance may be made in respect of qualifying expenditure on a building.
• The allowance is written off at the point when the building is first used.
• The full amount of the initial allowance is written off at that single point in time.
• This timing rule links the write-off to actual use of the building rather than to the date expenditure was incurred or the allowance was claimed.
