EV salary sacrifice lets you lease an electric car through your employer using pre-tax salary, so you avoid Income Tax and National Insurance on the amount sacrificed — typically saving 20–50% versus a personal lease. The only tax you pay back is Benefit-in-Kind (BiK), just 4% of the car's value in 2026/27, rising to 5% (2027/28), 7% (2028/29) and 9% (2029/30). It only works through an employer that offers a scheme, your reduced salary must stay above minimum wage, and you usually lose the car if you leave the job. Combined with the £3,750 Electric Car Grant, it's often the cheapest way to drive a new EV.

What salary sacrifice actually is
Salary sacrifice is a formal change to your employment contract: you agree to give up a set amount of gross (pre-tax) pay each month in exchange for a non-cash benefit — here, the use of an electric car your employer leases. Because Income Tax and employee National Insurance are calculated on your reduced salary, the cost of the car is met from pre-tax earnings rather than your take-home pay. That is where the saving comes from.
Why EVs specifically
Any car can in theory be offered, but the maths only stacks up for fully electric cars because of the tiny Benefit-in-Kind charge. BiK is the tax you pay on a perk provided by your employer. For petrol and diesel cars it can be 25–37% of the car's value; for pure EVs it is just 4% in 2026/27. That low rate is what lets the Income Tax and NI savings flow through to you almost untouched.
A worked example
Figures are illustrative — your exact saving depends on your tax band, the car and your employer's scheme — but they show the shape of it. Consider a 40% taxpayer sacrificing £6,000 a year (a £500/month lease):
| Item | Approximate effect |
|---|---|
| Income Tax saved (40%) | ~£2,400/year |
| Employee NI saved | ~£480/year |
| Employer NI saved (passed on or shared) | ~£900/year |
| BiK tax paid back (4%) | Small — a few hundred £/year |
| Net effect | Car costs far less than a £500 personal lease |
Lower-rate (20%) taxpayers still save, just less, because the Income Tax relief is at the lower rate. Higher and additional-rate taxpayers save the most.
How the savings are built
- Income Tax relief: you don't pay tax on the sacrificed salary (20%, 40% or 45% depending on your band).
- Employee NI relief: you also avoid employee National Insurance on the sacrificed amount.
- Employer NI relief: with the employer NI rate at 15% in 2026/27, employers save too — many run schemes at net-zero cost or pass savings on.
- Electric Car Grant: an eligible sub-£37,000 EV can have £1,500–£3,750 taken off first, reducing the lease the sacrifice is based on.
- Bundled costs: schemes typically include insurance, maintenance, tyres and breakdown cover in the monthly figure.
Salary sacrifice isn't free money. Your reduced salary can affect mortgage affordability assessments, pension contributions (if based on the lower figure), and statutory pay. You usually hand the car back if you leave the job, are made redundant or go on extended unpaid leave — check early-termination terms. And your reduced salary must not drop below the National Minimum/Living Wage, which can exclude lower earners.
Who benefits most — and who doesn't
- Best fit: higher-rate taxpayers with stable employment, an employer scheme, and somewhere to charge — the savings are largest and the risks smallest.
- Still worthwhile: basic-rate taxpayers, who save less but often still beat a personal lease once insurance and maintenance are bundled in.
- Poor fit: those near minimum wage (the floor blocks it), people likely to change jobs soon, or anyone whose mortgage or pension would be hurt by a lower headline salary.
How to get started
- Check whether your employer already offers a scheme (often via a third-party provider).
- Use a reputable salary-sacrifice calculator to estimate your net monthly cost at your tax band.
- Pick an eligible EV — confirm whether the £3,750 Electric Car Grant applies (price under £37,000).
- Confirm what's bundled (insurance, servicing, tyres) and the early-termination/leaver terms.
- Check the impact on your pension, mortgage plans and any benefits before signing.
