UK Tax Guide — April 2026
Salary sacrifice is where you agree to give up part of your gross salary in exchange for a non-cash benefit — most commonly a pension contribution or electric company car. Because this reduces your gross pay before tax you pay less income tax and National Insurance — and so does your employer.

What Can You Sacrifice Salary For?
Benefit
Tax and NI Saving
Pension contributions
Yes — full income tax and NI saving — most popular
Electric company car
Yes — very low BIK rates in 2026
Cycle to work
Yes — up to £1,000 or £2,000 for e-bikes
Technology and gadgets
Yes in some employer schemes
Downsides to Be Aware Of
Reduces your contractual salary — may affect mortgage affordability
May reduce maternity or paternity pay if based on contractual salary
Can affect state benefits that are earnings-related
Your employer must agree to the arrangement
Mortgage tip: Tell your mortgage lender your full salary before sacrifice. Many lenders will accept the pre-sacrifice salary for affordability calculations.
Bottom line: Salary sacrifice for pension contributions saves a basic rate taxpayer around £960 per year on a £3,000 contribution. Electric company car schemes are also extremely attractive in 2026. Ask your employer if they offer either scheme — if they do take advantage immediately.
