Employers need to report all Benefits in Kind (BiKs), including those under the Optional Remuneration Arrangements (OpRAs) or “salary sacrifice” arrangements, to HMRC on form P11D from 6 April 2018, unless they are registered to voluntarily payroll benefits.

OpRAs are where an employee gives up the right to an amount of earnings in return for a Benefit in Kind (BiK) and includes flexible benefit packages with a cash option, cash allowances and salary sacrifice. All BiKs are now valued at the higher of the cash given up or the value of the BiK. Many previously non-taxable BiKs are now taxable, valued on the cash given up.

Note however that cars with emissions of 75g CO2 / km or less, pensions, pension advice, childcare and Cycle to Work benefits are unaffected.

Subject to a few specific exceptions, arrangements entered into on or before 5 April 2017 kept their previous tax treatment until the earlier of a renewal or variation of the arrangement. Such arrangements moved into the new rules on 6 April 2018.
