Salary Sacrifice EV

Is salary sacrifice safe? What HMRC's EV rules actually mean.

Q: Can salary sacrifice reduce adjusted net income?

Yes. Because the contribution is taken from gross pay before income tax is calculated, it lowers your adjusted net income, the figure HMRC uses to assess eligibility for benefits such as Tax-Free Childcare. Whether it helps in practice depends entirely on your own figures, so it is worth checking against your specific circumstances rather than assuming.

Q: What is the EV Benefit-in-Kind rate for 2026/27?

For a battery-electric car the Benefit-in-Kind rate is 4% of the list price in 2026/27, up from 3% the previous year. It rises by one percentage point a year on HMRC's published schedule, which still leaves electric cars well below the high-teens-to-37% bands that apply to petrol and diesel cars.

6 min read · 27 July 2026. If you are weighing up an electric car through salary sacrifice, the first question is rarely about the car. It is whether the scheme is real, whether HMRC could pull the rug, and whether the numbers still work for an ordinary salary. Here is what the tax rules actually say, in plain English.

The question behind the question

Salary sacrifice sounds like the kind of thing that gets quietly closed down. You give up part of your gross salary, a car turns up on your driveway, and the monthly cost is lower than you expected. When something looks that good, a sensible person asks where the catch is.

So it is worth being direct. EV salary sacrifice is not a loophole and it is not a scheme in the pejorative sense. It sits inside a statutory tax framework that HMRC itself defines, and for battery-electric cars that framework was left unchanged through both Budget 2025 and the Spring Statement 2026. The rules are public, the treatment is codified, and the position is stable. What varies is not the tax law. It is whether the employer offering it has structured the arrangement properly.

What HMRC actually says

Most salary-sacrifice benefits are caught by the Optional Remuneration Arrangement rules, usually shortened to OpRA. Those rules, introduced in 2017, strip away the tax advantage of sacrificing salary for a benefit by taxing you on the higher of the salary given up or the benefit's cash value.

Battery-electric cars are specifically exempt from OpRA. That exemption is the whole point. It means an electric car provided through salary sacrifice is taxed under the normal company-car Benefit-in-Kind framework, not clawed back by the anti-avoidance rules that apply to most other sacrificed benefits. This is a statutory carve-out written into the legislation, not a concession a provider has negotiated or a promise a broker has made.

The practical effect: you are taxed only on the Benefit-in-Kind value of the car, which for a zero-emission vehicle is low by design. For 2026/27 the BiK rate on a battery-electric car is 4% of its list price, up one point from 3% the previous year and rising by one point a year on a published schedule that runs to the end of the decade. Compare that with a petrol or diesel car, where BiK bands run from the high teens to 37% depending on emissions, and the reason the electric case works becomes obvious.

What that means in practice

The mechanics are what make salary sacrifice different from leasing a car privately. Your contribution comes out of gross pay, before income tax and National Insurance are calculated. A private lease is paid from what lands in your account after all of that has already been taken.

Because the deduction happens before tax and NI, the effective monthly cost of the car is lower than the sticker lease rate, by an amount that depends on your marginal tax and NI position. In exchange you pay Benefit-in-Kind on the car, which at 4% for an electric vehicle is modest. The net figure that leaves your take-home pay each month is almost always lower than financing the same car privately. It is not a guaranteed saving, though: your salary, the car and your circumstances all move the number, which is why worked examples only go so far.

Why the bundle matters

Heva pioneered the UK salary-sacrifice route to home solar, batteries and charging. Perx is the only Heva partner that adds the electric car to it, so the vehicle, the charger, the solar and the battery run through one gross-salary deduction, under one Covase employer relationship, with the Orbis IO platform managing each car in life. Not a car scheme with an energy add-on, and not an energy scheme that stops at the driveway. Both, in one.

A car on its own is only part of the cost picture for an electric vehicle. Where and how you charge it is the rest. That is why the offer employees see through Perx by Covase goes beyond the car and bundles the pieces that determine the running cost: the EV itself, a home charge point, and for those who want to go further, solar generation and battery storage, all inside a single managed salary-sacrifice arrangement.

It helps to be clear about who does what. Perx by Covase is the branded, employee-facing scheme, the thing you sign up to and interact with. Heva is the scheme structure that delivers the bundled EV, charger, solar and battery offer as one arrangement. And Orbis IO is the platform underneath, handling the in-life management and operational intelligence that keeps the scheme running properly once it is live. You deal with Perx; Heva shapes the bundle; Orbis keeps the engine running.

Bundling the home-energy add-ons with the car matters for a practical reason: a home charge point is not an accessory bolted onto an EV scheme. For many drivers it is the piece that unlocks the cost case, because charging at home is where the economics are strongest.

Why the employee case is broader than people think

There is a persistent assumption that salary sacrifice only pays off for higher-rate taxpayers. It is worth retiring. HMRC's own research into salary-sacrifice benefits found that around half of the employees using them were basic-rate taxpayers, so the advantage is not reserved for the top of the pay scale.

Charging is a large part of why. HMRC's Advisory Electricity Rates now distinguish by where you plug in: as of the mid-2026 update, 7p per mile for charging at home and 15p per mile for public charging. The more of your driving you fuel from your own driveway, the stronger the cost case, which is precisely why a bundled home charge point sits at the centre of the offer rather than off to one side.

One angle catches families off guard. Because salary sacrifice reduces your gross pay, it reduces your adjusted net income, the figure HMRC uses to test eligibility for Tax-Free Childcare. For a household sitting just above the threshold, sacrificing salary into an EV can bring adjusted net income back under the line and restore a benefit that had been lost. Whether it applies to you depends entirely on your own numbers, so treat it as a question worth checking rather than a promise, but it is a real and frequently overlooked part of the picture.

Not a niche any more

If part of the safety question is really "is this a mainstream thing or a fringe arrangement", the market has answered it. Salary sacrifice has become one of the fastest-growing routes into a new car in the UK, and the BVRLA's leasing data has tracked salary-sacrifice volumes climbing year on year as more employers add the benefit. This is no longer an early-adopter curiosity. It is a standard part of how UK employees are getting into electric cars.

So, is it safe?

The honest answer is that "safe" is the wrong frame. EV salary sacrifice is not a trick that might be found out. It is a statutory tax treatment for battery-electric cars, left deliberately intact through the last two fiscal events, sitting inside the normal Benefit-in-Kind rules rather than outside them. The real question is not whether the mechanism is legitimate. It is whether the scheme in front of you is properly structured, clearly explained, and managed well once it is live.

That is the part an employer controls, and it is the part Perx by Covase is built to get right. If you want to see what it looks like against your own salary and mileage rather than a generic example, the Perx calculator lets you configure the car, a home charge point and the home-energy add-ons and see an indicative net monthly figure: run your own numbers. Employers weighing up whether to offer the scheme can start with a free fleet review.

All figures are indicative and nothing here is personal financial or tax advice. Benefit-in-Kind rates, advisory rates and eligibility thresholds are set by HMRC and can change; the VAT treatment of public charging is separately subject to an ongoing appeal. If your situation is finely balanced, check it against your own numbers before you decide.

Frequently asked questions

Is EV salary sacrifice still legal in 2026?
Yes. Battery-electric cars are exempt from the Optional Remuneration Arrangement rules and are taxed under the normal company-car Benefit-in-Kind framework. That statutory position was left unchanged in both Budget 2025 and the Spring Statement 2026.

Can salary sacrifice reduce adjusted net income?
Yes. Because the contribution comes out of gross pay before tax, it lowers your adjusted net income, the figure HMRC uses to assess eligibility for benefits such as Tax-Free Childcare. Whether that helps you depends on your own figures, so it is worth checking against your specific circumstances.

Is salary sacrifice only worth it for higher-rate taxpayers?
No. HMRC research into salary-sacrifice benefits found that around half of the employees using them were basic-rate taxpayers. The advantage comes from paying for the car out of gross pay and the low Benefit-in-Kind rate on electric vehicles, both of which apply regardless of your tax band.

What is the EV Benefit-in-Kind rate for 2026/27?
For a battery-electric car it is 4% of the list price in 2026/27, up from 3% the year before. It rises by one percentage point a year on HMRC's published schedule, which still leaves electric cars far below the high-teens-to-37% bands that apply to petrol and diesel.
