In the illustration three covering the capital allowances, the long life asset is GBP530,000 and the machinery is GBP45,000. Why was the total long life asset classified as AIA, why not 45k as AIA and then 455k of the 530k as AIA then 75k as Special rate pool?
We apply the available AIA firstly to special rate pool expenditure as any remaining expenditure will only rank for 8% WDA whereas any main pool expenditure not available for AIA will benefit from 18% WDA, Read carefully the OT course notes and listen to the lectures which hopefully explain these issues.
