Top Sacrifice Benefits
Most popular workplace schemes in 2026
Workplace Pensions
The most common scheme. Sacrificing salary into a pension saves you Tax and NI, and crucially, does not count towards the National Minimum Wage floor.
Electric Vehicles (EVs)
With a Benefit in Kind (BIK) rate of just 4% for 2026/27, leasing an EV through salary sacrifice is vastly cheaper than a personal lease, saving thousands annually.
Cycle to Work
Save 20-42% on a new bicycle and safety equipment. The cost is deducted from your gross salary over 12-18 months, making it highly affordable.
Childcare Vouchers
For employees who joined a scheme before October 2018, salary sacrifice childcare vouchers remain a highly tax-efficient way to pay for registered childcare.

Salary Sacrifice FAQ
Answers to the most frequently asked questions about workplace salary exchange schemes, eligibility, and financial impacts.
Salary sacrifice (or salary exchange) is an agreement between an employer and employee where the employee gives up a portion of their pre-tax salary in exchange for a non-cash benefit. Because your gross salary is reduced, you pay less Income Tax and National Insurance on that amount.
It can. Mortgage lenders typically assess your affordability based on your post-sacrifice (lower) gross income. However, pension contributions are often added back by lenders, and some employers will provide a formal letter confirming your pre-sacrifice salary specifically for mortgage applications.
For the 2026/27 tax year, the Benefit in Kind (BIK) rate for fully electric vehicles (EVs) is 4%. This remains significantly lower than petrol or diesel cars, making EV salary sacrifice schemes highly tax-efficient for both employees and employers.
No. By law, your post-sacrifice salary cannot fall below the National Minimum Wage (NMW) or National Living Wage (NLW) for the hours you work. The only exception to this rule is pension contributions, which can legally take your pay below the NMW threshold.
Yes, but it depends on the specific scheme’s terms. Most schemes allow you to opt out at the end of a fixed term (e.g., after a 12-month cycle to work agreement) or during designated enrollment windows. Some schemes may allow early opt-out due to a significant change in personal circumstances, such as a drop in income.
