How Salary Sacrifice for a Bike Actually Saves You Tax: 2026/27 Worked Example

How Cycle to Work Salary Sacrifice Works

Under a cycle to work scheme, your employer buys a bike (and often safety equipment) on your behalf, then you "hire" it from your employer over an agreed period — typically 12 months — through a salary sacrifice arrangement. Each month, an amount is deducted from your gross salary (before tax and National Insurance are calculated) to cover the hire cost.

Because the deduction happens before tax and NI, you never pay income tax or NI on that portion of your salary — this is the core saving mechanism, distinct from a simple discount or voucher scheme.

Worked Example: £1,000 Bike, Basic Rate Taxpayer (2026/27)

Assume a £1,000 bike hired over 12 months (£83.33/month sacrifice), for a basic-rate taxpayer earning within the basic rate band (income between the £12,570 personal allowance and £50,270 upper earnings limit).

That's a 28% discount purely from the tax and NI treatment — before even accounting for any employer-negotiated discount on the bike's retail price, which many scheme providers also secure.

Worked Example: Higher Rate Taxpayer

A higher-rate taxpayer sacrificing salary that falls above the £50,270 upper earnings limit saves less on NI (2% rather than 8%) but more on income tax (40% rather than 20%), giving a combined saving of roughly 42%.

Employer National Insurance Savings Too

The employer also benefits: reducing an employee's gross pay reduces the employer's Class 1 secondary NI liability (15% in 2026/27, above the £5,000 secondary threshold) on the sacrificed amount. Many employers pass some or all of this saving back into the scheme, for example by covering scheme administration costs, which is one reason cycle to work schemes are widely offered at no direct cost to employers.

What Happens at the End of the Hire Period

At the end of the typical 12-month hire period, you're usually offered a few options:

HMRC publishes indicative fair market value percentages — for example, a bike originally costing under £500 might have a fair market value of around 18% of the original price after 12 months, rising percentage-wise the longer it's been owned but declining as an absolute value. Scheme providers use these published tables to calculate the exact final payment.

Practical Considerations Before Signing Up

• Check the scheme's spending cap with your employer/provider — commonly used caps exist to keep agreements below Consumer Credit Act/FCA credit-broking thresholds unless your employer holds specific permissions.
• Confirm how sacrifice affects your pension — if your pension contribution is calculated as a percentage of gross salary, a lower sacrificed gross salary can mean a slightly lower pension contribution in cash terms, even at the same percentage rate. Ask your employer whether pension contributions are calculated on pre- or post-sacrifice salary.
• Consider proximity to key thresholds — sacrificing salary that pushes you below £100,000 (avoiding personal allowance taper) or below £60,000 (reducing High Income Child Benefit Charge exposure) can create additional value beyond the direct scheme savings, though this is a secondary consideration, not the primary reason to use the scheme.
• Make sure the bike is genuinely for commuting — HMRC's qualifying conditions expect the bike to be used mainly for journeys to/from work or work-related travel, though some private use is permitted.
