BIM35101 - Capital/revenue divide: basis of computation: income tax is charged on profits

Legislative starting point

ICTA88/S18 (1)(a)(ii) provides that tax is charged on the annual profits or gains arising or accruing ‘from any trade, profession or vocation, whether carried on in the UK or elsewhere’.

The legislation does not define 'profits or gains'. In Ryall v Hoare [1923] 8TC521, a Case VI Schedule D case concerning the taxability of commission received by a company director for guaranteeing the company’s overdraft, at page 525 Rowlatt J described profits or gains as “…something which is in the nature of interest or fruit, as opposed to principal or tree”.
