CFM10531 - Currency transactions and accounting: IBA and other capital allowances

Straight line capital allowances

This guidance describes the post-FA 2002 taxation of loan relationships, derivative contracts and FOREX.

Some other capital allowances, such as Industrial Buildings Allowance and Agricultural Building Allowance, are given on a straight-line basis based on the original expenditure that qualifies for the allowance. In the case of Research and Development Allowance, the allowance will normally be 100% of the original expenditure.

Capital allowances of this kind are also computed in the currency of the accounts. The amount of the allowance will be based on the original qualifying expenditure, expressed in the currency of the accounts. If the original expenditure was in a different currency (including sterling), the expenditure should be translated into the reporting currency at the exchange rate for the day on which it was incurred - see CA11750.
