duality


Show Summary Details

Quick Reference

A principle of UK income tax and corporation tax under which expenditure is not deductible in computing the profits subject to tax if the expenditure has a dual purpose. A deduction in computing trading profits is therefore denied for any expense not incurred wholly and exclusively for the purposes of the trade. The duality principle refuses relief by apportionment of a payment but permits relief where a wholly business expenditure can be identified by dissection of a payment.
