Are salary sacrifice car schemes worth it? Pros, cons and the maths

Is salary-sacrificing a car worth it? For most people whose workplace offers a scheme it is, and there are three main things to take into account: your tax band, how much you want to spend on the car, and how sure you are about staying in your job. 

This page covers salary sacrifice for electric cars rather than pensions, but there's a short section on the 2029 pension change further down. It should be helpful whether you’re an employee weighing up getting an electric car, or an employer deciding whether to offer an EV salary sacrifice scheme to your team. 

• If you're an employee, a salary sacrifice car usually costs less from your take-home pay than leasing the same electric car yourself, because you save on National Insurance and Income Tax, and electric cars carry a low Benefit-in-Kind rate.
• If you're an employer, the scheme is usually cost-neutral. You save employer National Insurance on the amount sacrificed, and pay a smaller amount of Class 1A on the car benefit.
• Salary sacrificing a car may not be worth it for everyone. If you don’t want a fully electric car, the tax benefits of salary sacrifice are basically non-existent for petrol and diesel cars now, and over the coming years hybrids won’t be as tax-efficient either as the BiK rate on hybrids is set to rise. 
• The maths turns on your tax band and on the Benefit-in-Kind rate, which is 4% for the 2026/27 tax year and will rise to 10% by 2030/31.
• The April 2029 salary sacrifice change you may have heard about applies only to pension contributions. Car schemes aren't affected by it.

Salary sacrifice allows an employee to give up part of their pre-tax salary in exchange for a non-cash benefit. Your employer leases the electric car and you pay for it from your salary before Income Tax and National Insurance come out. So you pay less of both taxes than you would if you got that money as cash from your employer. 

HMRC treats this as an agreement to reduce your pay, rather than a deduction from it. That distinction is what brings the tax benefits. Your taxable pay is genuinely lower, so you pay less Income Tax and less National Insurance.

Most benefits lost this advantage in 2017. Electric cars didn't, because cars emitting 75g/km or less carbon sit outside the updated rules. That’s the reason electric car salary sacrifice is growing in popularity.

You do pay a small amount of tax on the car itself, called Benefit-in-Kind, or BiK. For a fully electric car it's charged on a percentage of the list price, and that percentage sits at 4% for the 2026/27 tax year. On a £40,000 car, that's £1,600 of taxable benefit a year, which is what you pay Income Tax on, rather than the full cost of the car.

If you want to understand how salary sacrifice works, step by step, our guide to how it works walks through it. 

Usually, yes, whether you're a lower or higher rate taxpayer, and expect to stay with your employer for the length of the lease. You get a new electric car for less than you'd pay to lease it yourself, with the running costs bundled in. What you give up is the flexibility around moving companies while you’re leasing the car, and a slice of anything tied to your salary. 

If you’re looking for a petrol or diesel car, salary sacrifice probably isn’t the most cost effective option. That’s because HMRC has set their Benefit-in-Kind rate at between 17% and 37%, which cancels out most, if not all of your tax saving. If you’re looking for a hybrid on salary sacrifice, the picture isn’t quite as bleak, but it’s still not great compared with a fully electric car. The benefit-in-kind rate for hybrids is currently 4-16%, depending on your model’s electric range. In the 2028/29 tax year, this will rise to 18%, and by 2029/30 it’ll be 19%. Bear in mind that most contracts are 3-4 years long, so you’d want to factor that in for a lease starting this year. 

The biggest gain from EV salary sacrifice is the tax saving you make because the money for your car comes out before tax. If you're a higher rate taxpayer, a large part of what the car costs would have gone to HMRC anyway, which is why the same car can cost a 40% taxpayer noticeably less than a 20% taxpayer.

The second gain is that there's nothing to put down up front. Personal leasing and dealer finance usually want a deposit of several months' payments up front. With Octopus EV’s salary sacrifice, you pay nothing up front. 

The third gain from EV salary sacrifice is that one payment covers almost everything. The car, your insurance, servicing, maintenance, tyres and breakdown cover are included in the monthly figure. There's no MOT bill to plan for and no repair bill that arrives without warning.

With Octopus EV, you also get a choice of exclusive charging offers to get you started. £400 off a home charger (installed by Octopus Energy Services), £400 of public charging credit, or £400 of home charging credit. See the details here.

It’s worth understanding the package before you weigh the price up vs other options. A salary sacrifice figure that looks higher than a lease quote often isn't, once you add the insurance, servicing and tyres you'd be paying for separately.

Your reduced pre-tax pay affects anything calculated from salary. You're tied into the lease for its full term. And the car doesn’t become yours at the end of your contract.

Pension contributions are the clearest example of the first point. If your pension contributions are a percentage of your salary, a lower salary means smaller contributions from both you and your employer, unless your scheme is set up to ignore the sacrifice. Statutory maternity pay and other statutory payments are worked out from earnings too, so a sacrifice running through the qualifying period can reduce them. None of that is hidden, and for most people the savings on the car outweigh it. But it's something that can be easily missed, so it’s worth checking what applies to you before you order.

You're signing up for three or four years, and if you leave your job partway through the car normally goes back, sometimes with an early return fee attached. With Octopus EV, that’s 50% of the remaining contract value. But we know life happens and your circumstances can change. Our early termination protection allows drivers to give their car back before the end of their contract if their circumstances change, and it’s for your employer to decide if and how they use it. See the full details on our early termination cover here. 

And when the term finishes, you return the car, rather than keep it like you would with a PCP contract. 

A salary sacrifice car costs you a certain amount pre-tax pay, minus the Income Tax and National Insurance you no longer pay on it, plus Benefit-in-Kind on the car itself. The net figure is what your take-home pay actually drops by, and that's the number to compare against what your current car costs you.

So is salary sacrificing a car worth it? For most people it comes down to that net figure.

Here's the same electric car, taken by two people on different salaries, over a 3 year contract.

These numbers are based on our pricing in September 2026, for someone earning £50k a year (lower rate tax payer example) and someone earning £90k per year (higher rate tax payer example). It’s based on a 3 year contract, with insurance included, driving 10,000 miles a year, date of birth of 01/01/1984, a KT23 postcode, with the employer passing back 10% of their employer NI saving and recovering 100% of the VAT. The BiK rate is for the 2026/7 tax year. Subsequent years will be higher.

Your tax band has the biggest impact on what you save. The higher the rate you pay on the slice of salary you're giving up, the more the sacrifice is worth, which is why the two columns above differ as much as they do. 

The car matters next, because BiK is charged on its list price. A more expensive car means a bigger taxable benefit, even at the 4% Benefit-in-Kind rate.

Where you live changes it too, because insurance is priced by postcode and is usually inside the monthly figure.

If you pay Scottish Income Tax, the bands are different and these examples won't map onto your payslip. The principle would stay the same, but the numbers would change. For a figure based on your own salary and the car you actually want, if your employer is already with Octopus EV you can get an accurate EV salary sacrifice quote by logging in.

The monthly cost is only part of the comparison you should do, if you drive a petrol or diesel car at the moment. The other important part to compare is how much you’ll save on fuel costs.

Charging at home makes the biggest difference. A full charge at home can cost just £4.32 in a typical electric car, compared with £38.74 for the same miles in an equivalent petrol car, as of 1st October 2026. 

That saving you’ll make depends on charging overnight on an EV tariff. Intelligent Octopus Go - EV Saver is Octopus Energy's fixed home charging tariff, and a discounted 6.9p per kWh rate is exclusive to Octopus EV drivers. Public charging costs more, so the savings shrink a bit if you can't charge at home. Our guide to the cost of charging covers public rates in detail.

Then there's the maintenance, repairs and unexpected bills for tyres you're no longer paying for separately, because they’re already included in the monthly figure with salary sacrifice. Electric cars have fewer moving parts to service too, so there's less to go wrong.

You agree on an annual mileage when you order, and the monthly cost is built around it. Go over it across the life of the lease and you may pay a charge per excess mile at the end. The rate depends on the car and the scheme, so check yours before you sign. 

The important thing is to be honest with yourself when you order. People often underestimate their mileage to bring the monthly figure down, then pay for it three years later.

If your mileage is genuinely unpredictable, pick the higher allowance. The monthly difference is usually small next to an excess charge on several thousand miles.

The scheme suits some situations much better than others, and these are the ones where the maths usually doesn't work.

• If you plan to change jobs. The scheme runs through your employer, so leaving partway through a lease usually means giving the car back, and possibly paying something to do so. If you're actively looking to move companies, wait.
• If you're close to retiring. A three or four year commitment doesn't fit inside 18 months of working life.
• If your earnings are near the minimum wage limit. Sacrifice can't take your pay below the National Minimum Wage, so lower earners may not be eligible at all.
• If your current car is cheap to run, old, and paid for. A salary sacrifice car is a better deal than most ways of getting an electric car. But if you’re running your current car into the ground and it’s cheap to do so, salary sacrifice may not be the option for you.
• If you’re sticking with petrol, diesel, or hybrid. The tax savings on cars that aren’t fully electric aren’t as lucrative. 

For most employers, yes. The scheme is normally close to cost-neutral, because the employer National Insurance you save on the sacrificed salary is usually larger than the Class 1A you pay on the car. The real costs are administrative rather than financial, and the real risk is what happens when someone leaves.

When an employee sacrifices salary, their pay goes down. You no longer pay employer National Insurance on the amount they’re sacrificing, so with Octopus EV that saving is yours to keep and spend on what you like. Some providers keep your NI saving to cover ‘admin fees’ so it’s worth checking before you pick who you go with. 

The car is a taxable benefit, so you pay Class 1A National Insurance on it. Here’s how that works.

Take an employee on £60,000 who sacrifices £6,000 a year for a £40,000 electric car, in the 2026/27 tax year. You save £900 of employer National Insurance on the sacrificed amount. The Benefit-in-Kind is £1,600, so the Class 1A due is £240. That leaves the business about £660 better off per car per year. Twenty cars is roughly £13,200, and 50 is roughly £33,000.

That's an illustration rather than a quote, and it changes with the car, the salary and the BiK rate. 

There's no payback period, because there's nothing to pay back, and your savings will grow as more people take cars on the scheme.

Setting a scheme up is free with most providers, Octopus EV included. The ‘costs’ you’ll want to understand are the ones measured in your team's time.

Payroll will pick up the ongoing work, but it's light once the scheme is up and running. A deduction goes on the payslip each month, and you report the benefit to HMRC. Involve payroll early, though. They're the team most likely to raise an objection late, and they're usually right to, because they're the ones who'll live with it. Our payroll guide to salary sacrifice gives them all the details they’ll need to get on board. 

Your HR or employee benefits lead will probably handle approvals and answer your team’s questions. We support you to launch the scheme, promote it to your team and will give you everything you need to answer any questions your team has. We often run webinars to explain how it works, and can even visit your offices to talk to your team directly. There’s some admin, as you’d expect, at the start, to cover who will be eligible to take part, and getting the policy signed off, but again we’ll support you through the whole process. 

Your business signs the lease on every car in the scheme, so the contract sits with you, the employer, rather than with the employee. But in reality, the number of early returns we get is smaller than most employers expect. If someone leaves partway through, they’ll return the car, which we offer early termination cover for. 

We don't think “what ifs” should stand in the way of the tax savings, so this cover isn’t just a clause in a contract. It’s a safety net to protect both the business and the driver. As standard, most businesses have the following cover, but some have different terms, and it’s for you to decide if and how you use your early termination cover.

If someone resigns, is made redundant or is dismissed, they can return the car free of charge after an initial period. Unlike other providers who make the business pay the exit fees up front and then claim them back from a separate insurer, which can take months, our cover is built into the scheme, so when a car comes back there’s simply nothing to pay.

Life events are covered from day one, with no waiting period. For parental leave, we cover up to 12 months as a ‘payment holiday’, or the driver can return the car. Unlike other providers who cap this at £500, we cover the full monthly cost. If a driver is off sick for four weeks or more, they can keep the car and we’ll cover the monthly cost for up to three months, or they can return it. For both, the driver just needs to show that their pay would drop below the National Living Wage with their salary sacrifice to qualify. If a driver loses their licence for six months or more for medical reasons, we’ll take the car back free of charge. And on the death of the driver, their spouse or partner, we’ll work with the family to return the car free of charge at the right point for them.

There is a cap on covered returns: 10% of your fleet or 10 cars a year, whichever is higher. Very few organisations get anywhere near it. In 2026, from January to July, 99% of organisations that made at least one early return stayed within this cap. If you go over, you’ll pay the early termination fees on the cars that go above the cap, within that calendar year. There’s no change to your cover in subsequent years.

If the cover doesn’t apply to the specific reason for returning the car early, for example a change of heart, there’s an early return charge of 50% of the remaining contract value. But the large majority of early returns are covered.

Don't take that on trust from a provider, including us. Ask for the actual return rates, what's covered, what isn't, and what an uncovered return costs. Our guide to early termination risk sets out the scenarios and the numbers, and our cover is explained in full.

• If you’re a sole trader or director mainly paying yourself in dividends, your PAYE may not be high enough to benefit from the tax savings, so business contract hire may be more suited.
• If you have high staff turnover and a small number of eligible staff, salary sacrifice might not be right for your business. Churn shrinks the number of people who can take a car and raises the number of early returns, which can make it less successful.
• If most of your team don’t earn over £31,000, you may want to reconsider because most of them won't be eligible, as salary sacrifice can’t take their gross pay below the National Minimum Wage.

No. From 6th April 2029, only the first £2,000 of pension contributions made through salary sacrifice will be exempt from National Insurance. It applies to pension contributions and nothing else. Car schemes are outside it and carry on as they are.

This is worth stating plainly because the two often get confused. The announcement generated a lot of news coverage asking whether salary sacrifice was still worth doing, and almost all of it was about pensions.

If you're reading this because of that change and your question is about your pension rather than a car, the answer is that your first £2,000 of contributions is unaffected, and the change starts in 2029. Speak to your pension provider or a financial adviser about what it means for you.

If you're an employee and your employer offers a scheme through us, you login to choose a car and the cost comes out of your pre-tax salary each month. The monthly figure covers the car, its insurance, servicing and maintenance, tyres and breakdown cover. You also get a discounted home charger or charging credit, plus access to Intelligent Octopus Go - EV Saver, Octopus Energy's home charging tariff, which is exclusively discounted for Octopus EV drivers. 

If you're an employer, our salary sacrifice scheme is free to set up, and the admin is minimal as it’s mainly managed online, through a dashboard. Cover for leavers and life events is built into the scheme. Unlike other providers who make the business pay the exit fees up front and then claim them back from a separate insurer, which can take months, there’s simply nothing to pay when a covered car comes back. And the car, the charger and the energy tariff come from one place, so you don’t have 5 different providers to deal with. If you're building the internal case, our guide to preparing a business case is written to be forwarded to the people who'll ask the hard questions.

You're tied in for three or four years, and leaving your job usually means handing the car back. Your reduced pre-tax pay can lower pension contributions, statutory pay and what a mortgage lender will offer. And the Benefit-in-Kind rate is set to rise each year, so the cost creeps up. Although the tax savings on fully electric cars are still big.

Usually, compared with leasing the same electric car yourself, because you pay from pre-tax salary and electric cars carry a low Benefit-in-Kind rate. With Octopus EV, insurance, servicing, maintenance, tyres and breakdown cover are included as well. 

It depends on your tax band and the car you choose. A 40% taxpayer saves more than a 20% taxpayer on the same car, because a bigger slice of the money would otherwise have gone to Income Tax and National Insurance. 

Usually not. Your employer reports the car as a benefit, so there's nothing for you to file separately. You may see your tax code change, because Benefit-in-Kind is normally collected that way. If you complete a Self Assessment return, include the benefit your employer reports.

Yes, for cars. The April 2029 change that prompts this question caps the National Insurance exemption on pension contributions at the first £2,000 a year. It applies to pensions and nothing else. Salary sacrifice car schemes sit outside it and carry on unchanged.

With Octopus EV, there's no set-up fee. The real cost is internal time: agreeing eligibility, getting the policy approved, connecting it to payroll and telling people it exists. Once it's running, the monthly work is minimal, covering just payroll deduction and reporting the car benefit.
