Update from the cyclescheme website:
HMRC have recently supplied the matrix they apply when valuing a bike at the end of the hire period, which we welcome as guidance.
Cyclescheme would like to reassure our clients that we have a process in place that ensures our schemes continue to be compliant, whilst retaining their attractiveness to employees and employers alike. More information is available on the Employer's page.
We would like to clarify that if an employer sells the bike to the employee at less than the HMRC guided percentage (as most will choose to do), the employee will only have to pay tax and National Insurance on the difference in these two amounts and not have to pay the final value amount.
For example, a £500 bike undamaged, after 12 months would have a market value (using the HMRC matrix) of £100. Should the employer sell the bike to the employee, for £5 then tax and national insurance would need to be paid on the £95, and the employee would not pay £95.
