For an explanation of what is a salary sacrifice, see
EIM42750.
For the income tax effects of a salary sacrifice, see
EIM42755.
Salary sacrifice arrangements are effective when the
contractual right to cash remuneration has been reduced. For this
to happen two conditions have to be met:
If the salary sacrifice is effective, and if the employee receives a non-cash benefit instead, you should also look to see if the employee has the right to give up the benefit at any time and revert to the original (higher) cash salary. If they can, the non-cash benefit may be taxable as “earnings” within Section 62 ITEPA 2003 (see EIM42753 and EIM00570). Some benefits are exempt from income tax altogether in which case no earnings charge can arise. See EIM42755.
