EIM21201 | The benefits code: more on apportionment of the cash equivalent of the benefit: Westcott v Bryan
From HM Revenue & Customs · Employment Income Manual
There is no statutory guidance on how to do a “proper apportionment” (Section 204 ITEPA 2003).
Westcott v Bryan (45TC476)
The only judicial guidance is in Westcott v Bryan. That case was concerned with legislation which preceded the current rules and the facts of the case are a little difficult to follow, but the general principles set out by the judges apply to “proper apportionment”. The following principles emerge from the case:
where there is use of something, both by an employer for their own purposes and as a benefit by a director, there should be an apportionment,
there are no fixed rules or precise formulae about how to do the apportionment,
the apportionment must be based on the facts of the case, and lead to a result which is fair and reasonable.
Lord Justice Sachs commented (page 493) on the calculation of the apportionment:
“such an apportionment must …… necessarily be on a rough and ready basis. One must, of course, be on strict guard to avoid abuses such as by provision of benefits merely in reality adding to the remuneration of a director; but to my mind no precise formula can as a rule be applied”.
