Electric car salary sacrifice: 10 questions employees ask

If you’re looking at getting an electric car through salary sacrifice you may have a few questions about how it works. Chances are they’re in this list. Here are the 10 most common questions we get asked. 

If you’re the one running an EV salary sacrifice scheme at your company, bookmark this page to share with your team, you’ll thank us later. 

Salary sacrifice is an arrangement where you give up part of your pre-tax salary in exchange for a non-cash benefit. With a car scheme, your employer leases an electric car and you pay for it from your salary before Income Tax and National Insurance come out. Because electric cars have a low Benefit-in-Kind rate, the cost to your take-home pay is usually lower than leasing the same car yourself. 

Your employer holds the agreement with the leasing provider, not you. The amount comes off your pay each month, and your payslip shows a lower pre-tax salary as a result. Because the deduction happens before tax, you're paying for part of the car with money that would otherwise have gone to HMRC. How much that's worth to you depends on your tax band.

There's more detail in our guide to how salary sacrifice works and in our employee guide to the scheme.

Your employer decides. Salary sacrifice is an employee benefit, so it's only available if your employer runs a scheme, and they set their own rules on who can join. Many ask you to have passed probation first.

There's one rule your employer can't change. Sacrificing salary can't take your pay below the National Minimum Wage or National Living Wage, currently £12.71 an hour for people aged 21 and over. That rules some lower-paid roles out entirely. Some employers also set a minimum length of service. Your HR team or your benefits portal will tell you where you stand, but a good rule of thumb is your salary needs to be above £31,000 a year. 

Our guide to the HMRC rules covers what the tax rules require, as opposed to what your employer chooses.

Less than the headline figure. Quotes are often shown as a pre-tax amount, which is what comes off your salary before tax is worked out. What actually leaves your take-home pay is lower, because the sacrifice reduces the Income Tax and National Insurance you pay.

This is the thing some people get caught out by. A car quoted at a pre-tax figure will reduce your take-home pay by noticeably less than that, and the gap is wider if you're a higher-rate taxpayer. You also pay Benefit-in-Kind tax on the car, which is a small amount, just 4%, on an electric car.

The only way to get an accurate number that’s tailored to your salary and your tax band is to get a quote. 

With Octopus EV, the car, servicing, maintenance, tyres and breakdown cover are included with salary sacrifice. Insurance is included as standard, though some employers opt out, so check with yours. You can choose between £400 off a home charger, or £400 of charging credit to get you started.

The benefit of a package like this is you're not hit with a separate bill when something wears out. Tyres, servicing and the MOT are all in. What isn't included is anything you'd pay for on any car: electricity, parking and fines. Your agreement also sets an annual mileage, and going over it costs extra, so be honest with yourself about how far you drive when you order. Our salary sacrifice page shows what comes with the car.

Yes, but not much. A car provided through your employer is a taxable benefit, so you pay Benefit-in-Kind tax on it. Electric cars are taxed at 4% of the car's list price for the 2026/27 tax year, well below the rates on petrol and diesel cars.

You pay that 4% at your own Income Tax rate, so the annual bill on most electric cars runs to a few hundred pounds rather than a few thousand. It's collected through your tax code rather than as a separate bill. The rate is set to rise in stages over the next few years, so a car you order now won't be taxed at 4% for its whole life. Our guide to P11D value explains the figure the tax is calculated from.

Usually. On a personal lease you pay from money that's already been taxed. On salary sacrifice you pay before tax, so the same car costs you less from your take-home pay, and there's normally no deposit to find.

It won't suit everyone. If you're a basic-rate taxpayer, or you're looking at an older or cheaper car than the scheme offers, a personal lease or buying used can work out better. The scheme is also tied to your job, which a personal lease isn't. Do you need to run both numbers? Probably, yes.

Our guide to whether salary sacrifice is worth it works through the comparison, and you can price up a personal lease alongside it.

Potentially. Salary sacrifice reduces your pre-tax pay, and anything worked out from that figure can fall with it. That includes pension contributions, statutory maternity and paternity pay, and how much a lender will offer you on a mortgage. The impact is likely to be minimal, but it’s worth being aware of.

Some employers protect pension contributions by basing them on your salary before the sacrifice, so ask yours. If you're planning a mortgage application or a period of parental leave in the next few years, raise it before you order. GOV.UK's guidance for employers sets out which entitlements are affected.

One thing that isn't a worry: the £2,000 cap on salary sacrifice pension contributions, which starts on 6th April 2029, applies to pensions only. Car schemes aren't affected.

You hand the car back. You're not signed to a finance agreement personally, so there's no loan to settle and nothing follows you to your next job. Whether handing it back costs you anything depends on why you're leaving and how your employer's scheme is set up.

Getting a car through salary sacrifice is a commitment, so you need to go into it with open eyes, 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.

As standard, most businesses have the following cover if drivers need to give the car back early. Some employers have different terms, so check your scheme's specific details. It's also for your employer to decide if and how they use their early termination cover. After an initial period, you can return the car free of charge if you resign, are made redundant or are dismissed. Life events are covered from day one, with no waiting period.

These are our standard terms, your own employer’s may differ. Check your own scheme terms with your employer.

Where a return isn't covered, the fee is invoiced to your employer, and they then recover it from your pay. 

Whether they can do that depends on your employment contract, because the rules on deductions from pay need either a term in it or your written agreement. Your scheme's driver handbook is where that sits, so read it before you order.

There's the full detail on what's covered, and our guide to leaving your job with a salary sacrifice car walks through each scenario.

Charging at home costs a lot less than filling up with petrol. You can do it for as little as 2p per mile, with an exclusive EV charging tariff from Octopus Energy, compared with 17p per mile for petrol. That discounted tariff is exclusive to Octopus EV drivers.

You don't need a driveway to make an electric car work, but home charging is where most of the saving comes from. If you can't charge at home, look at what's near your home, your work and the roads you drive most. It's also worth asking whether your employer has chargers on site. Public charging usually costs a bit more. Our guide to charging costs breaks down home against public charging.

The car goes back at the end of the agreement. Your employer holds the lease, so buying it isn't part of the scheme. If the scheme is still running, you can order another car when yours comes to an end.

The condition of the car matters when you hand it back. We check cars against the BVRLA's fair wear and tear standard, which is used across the leasing industry, so nobody's making a judgement call on the day. With Octopus EV, every car comes with a £500 damage waiver, and repairs over that amount that are charged to you. If you've driven further than the mileage on your agreement, there's a charge for the extra miles. The amount depends on the car so check what this is when you sign up. 

If your employer offers EV salary sacrifice through Octopus EV, you choose an electric car and the cost comes out of your pre-tax salary each month. Just login to check out the EVs available. 

The monthly amount covers the car, insurance, servicing, maintenance, tyres and breakdown cover. You can also choose a discounted home charger or charging credit alongside it.

What you end up paying depends on your salary, your tax band and the car you pick, so getting an accurate quote is the quickest way to see a real number. For advice on your own situation, speak to an accountant or tax adviser. Employees should check scheme terms with their employer.
