Key Takeaways
- A 40% taxpayer leasing a fully electric car through salary sacrifice can save roughly 30 to 60% on the all-in monthly cost compared to a personal contract hire deal in 2026/27.
- The benefit in kind rate for a fully electric car is 4% in 2026/27, compared to 25 to 37% for petrol and diesel cars, which is why salary sacrifice works best on electric vehicles.
- On a £35,000 electric car, a 40% taxpayer pays approximately £47 a month in benefit in kind tax, whereas the equivalent petrol car generates around £292 a month in benefit in kind tax.
- Salary sacrifice monthly figures typically bundle in insurance, servicing, tyres, and breakdown cover, costs that sit on top of a personal contract hire payment.
- HMRC has confirmed benefit in kind rates for electric cars through April 2030, giving enough certainty to sign a standard three or four-year lease today.
For a higher-rate taxpayer choosing an electric car, salary sacrifice almost always saves more than a personal lease, often close to a third of the effective monthly cost. That is because you pay for a salary sacrifice car from gross salary, before income tax and National Insurance, while a personal lease is paid from your take-home pay. The catch is that salary sacrifice needs an employer scheme and works best with electric vehicles. A personal lease is open to anyone, on any fuel, with no employer involved.
How Each Option Works
With salary sacrifice, your employer leases the car and you agree to give up part of your gross salary to cover it. Because that amount is taken before income tax and National Insurance, you save tax and NI on everything you sacrifice. The car is then taxed as a benefit in kind, which is a small charge based on the car’s value and its emissions.
A personal lease, also called a personal contract hire, works differently. You pay a fixed monthly rental from your post-tax income, the car is in your name, and the price includes VAT. There is no benefit in kind because your employer is not involved, so there is no tax perk to offset the cost. You can read more on our personal leasing pages.
Salary sacrifice usually bundles insurance, servicing, tyres and breakdown cover into the single figure taken from your pay. A personal lease typically covers servicing and maintenance as an option, but you arrange and pay for insurance yourself. That difference matters when you compare the two like for like.
Why Salary Sacrifice Is Cheaper for an EV
The reason electric cars work so well is the benefit in kind rate. For a fully electric car it is only 4% in 2026/27, rising gently to 5% in 2027/28, 7% in 2028/29 and 9% in 2029/30. That means the taxable benefit stays low while your tax and NI saving on the sacrificed salary stays high.
Petrol, diesel and most hybrid cars carry a much higher benefit in kind rate, sometimes 30% or more. That larger tax charge eats into the saving and can wipe out the advantage entirely. This is why almost every salary sacrifice car scheme in the UK is built around EVs.
There is a second saving that many drivers miss. Employers also cut their employer National Insurance bill when you sacrifice salary, and a good scheme often passes some of that benefit back to you. Our vehicle salary sacrifice guide explains how the numbers stack up in more detail.
An Illustrative Comparison for a Higher-Rate Taxpayer
Imagine a 40% taxpayer looking at the same electric car under both options. The following figures are illustrative and rounded, so treat them as a rough guide rather than a quote.
Say a personal lease works out at an illustrative £500 a month from take-home pay, with insurance on top. Under salary sacrifice the gross cost might also be around £500, but because it comes out before 40% income tax and National Insurance, the real hit to your take-home pay could land nearer £320 to £340, with insurance already included. In this illustrative case the salary sacrifice route costs roughly a third less each month.
Your actual saving depends on your salary, tax band, the exact car and your employer’s scheme. Do not treat any of these numbers as guaranteed. Always confirm your own figures with a salary sacrifice calculator or an accountant before you commit.
Who Each Option Suits and the Catches
Salary sacrifice suits employed drivers whose employer runs a scheme and who want an electric car. If you fit that profile and you are a higher earner, it is usually the strongest value on the market. You can explore live schemes on our salary sacrifice hub.
A personal lease suits everyone else. That includes the self-employed, anyone without an employer scheme, and drivers who want a petrol, diesel or hybrid car. It is also the more flexible choice if your job may change soon, because the agreement sits with you rather than your employer.
The catches on salary sacrifice are worth knowing honestly. If you leave your job, the arrangement usually ends, and there may be an early exit cost, so check your scheme’s terms. A non-EV attracts a much higher benefit in kind charge, which is why the scheme rarely makes sense for petrol or diesel. Reducing your gross salary can also have a small effect on things like pension contributions and mortgage affordability calculations, though for most people this impact is minor.
Get a Clear Comparison for Your Situation
The honest answer is that salary sacrifice wins on cost for an EV if you have access to a scheme, while a personal lease wins on flexibility and works for everyone. The best choice depends on your employer, your tax band and the car you want. As a credit broker and not a lender, we can talk you through both sides plainly.

Frequently asked questions
Yes, but the savings are smaller than for a higher-rate taxpayer. A 20% taxpayer saves less on the gross pay reduction and pays benefit in kind tax at a lower rate, but the scheme can still produce a meaningful monthly saving on a fully electric car if you model the numbers for your specific salary and the car you want before committing.
Yes, personal use including commuting is permitted and is the norm, but any personal use means the car is treated as a taxable benefit and you will pay benefit in kind tax accordingly. The benefit in kind rate for a fully electric car is 4% in 2026/27, which is low enough that the tax charge does not cancel out the gross-pay savings for most employees.
The arrangement ends when your employment does, and your employer will set out the terms for early termination in the scheme agreement. In some cases you may be liable for early termination costs, so read the contract carefully before signing.
In 2026/27 they can be, depending on the car’s CO₂ output and electric-only range, but from 6 April 2028 all plug-in hybrids move to a flat 18% benefit in kind rate regardless of electric range. If your lease runs past that date, check the post-2028 benefit in kind cost carefully before signing.
For petrol and diesel cars, salary sacrifice is rarely cost-effective because benefit in kind rates sit between 25% and 37% in 2026/27. On a £35,000 petrol car at 25% benefit in kind, a 40% taxpayer faces an annual benefit in kind tax bill of £3,500, which typically wipes out the gross-pay savings from the scheme.
HMRC has confirmed benefit in kind rates for fully electric cars through April 2030. The rate rises from 4% in 2026/27 to 5% in 2027/28, 7% in 2028/29, and caps at 9% in 2029/30, meaning salary sacrifice schemes remain financially viable for anyone signing a standard three or four-year lease today.
