Specific deductions: staffing costs: share of profits
Remuneration to an employee (including a director of a company) calculated as a share of the profits of the business as a whole is normally allowable as a deduction. (See Stott and Ingham v Trehearne  9TC69, where remuneration so calculated was in part allowed.)
A deduction will therefore normally be allowed for remuneration taking the form of bonuses under a co-partnership or profit sharing scheme (as distinct from dividends, interest or bonuses on co-partnership stock).
In an exceptional case payments described as remuneration may in fact be distributions of profits after they have been earned, and so not a deductible expense of earning the profits (see, however, British Sugar Manufacturers Ltd v Harris  21TC528).
