EIM21005 | The benefits code: benefits chargeable under legislation other than the benefits code
From HM Revenue & Customs · Employment Income Manual
A benefit is not chargeable under the benefits code (EIM20006) if it is already fully chargeable to Income Tax under some other provision. For example:
benefits capable of being turned into money charged (the “money’s worth” principle) under section 62 ITEPA 2003, see EIM00540
benefits obtained by discharge of an employee’s debt (the “pecuniary liability” principle) under section 62, see EIM00580.
