Salary Sacrifice Car: How the Scheme Works in 2026

A salary sacrifice car lets you give up part of your gross salary for a car your employer leases for you. Because the sacrifice comes off before Income Tax and National Insurance are calculated, the saving can be large, especially with an electric car. Here is how it works, what it costs, and who it suits.

Key takeaways

  • You swap part of gross pay for a leased car, so tax and National Insurance fall with it.
  • The car is taxed as a benefit in kind, but an electric car attracts only 3% in 2025/26.
  • On £40,000 with a £400 monthly sacrifice, the example below lands at about £306 a month in real terms.
  • The sacrifice must never take pay below the National Living Wage, and it can affect pension and mortgage borrowing.
  • Leaving your job usually ends the agreement early, so check the exit terms first.

What is a salary sacrifice car scheme?

It is a formal agreement with your employer. You give up a set amount of gross salary each month for a leased car for business and private use. The change goes into your employment contract before the benefit starts, and HMRC guidance explains how it affects PAYE. Most schemes bundle insurance, servicing, maintenance, breakdown cover and road tax into one figure.

How a salary sacrifice car works

Your employer offers a choice of cars, and you pick one for a term of two to four years. You sign a revised contract with your new, lower salary. From the next pay run, payroll deducts it from gross pay before tax and National Insurance are calculated. The car is reported as a benefit in kind, taxed through your tax code or payroll. At the end of the term you hand it back.

Where the saving comes from

The saving is the gap between the tax and National Insurance you stop paying and the benefit-in-kind tax you start paying. On £40,000, every £100 sacrificed monthly saves £20 of Income Tax and £8 of National Insurance. The other half is the benefit-in-kind charge: the car's list price, or P11D value, times a percentage set by its emissions, then taxed at your Income Tax rate. A petrol or diesel car can reach 37%, wiping out most of the saving.

Worked example: £40,000 salary, £400 a month for an electric car

The figures below are illustrative. They use a £40,000 salary, a £400 monthly sacrifice, an electric car listed at £35,000, and the 2025/26 benefit-in-kind rate of 3%.

Gross pay falls from £40,000 to £35,200, a reduction of £4,800. Income Tax at 20% saves £960 a year, or £80 a month; National Insurance at 8% saves £384 a year, or £32 a month. Together, the sacrifice saves £112 a month.

The benefit-in-kind tax is separate. Three per cent of £35,000 gives a taxable benefit of £1,050 a year, which costs £210 a year at the 20% basic rate, or £17.50 a month. That leaves a net saving of £94.50 a month, so the true cost is £305.50 a month. A personal lease must beat that, including insurance and servicing, to come out cheaper.

In 2026/27 the electric rate rises to 4%, lifting the tax to £23.33 a month and the true cost to about £311. Check the current rate before committing to a long term.

Why electric cars win

It comes down to a rule from April 2017 on optional remuneration arrangements. Normally such a benefit is taxed on the higher of the salary given up and the normal benefit-in-kind value, which would end the advantage. Cars emitting 75g of carbon dioxide per kilometre or less are excluded, so they are taxed on the normal value alone. Rates are low and set years ahead, rising from 3% in 2025/26 to 9% in 2029/30.

Who a salary sacrifice car suits

The scheme suits settled employees who expect to stay for the full term and want a new electric car with most running costs bundled in. Higher-rate taxpayers save more. Unsure what it would do to your take-home pay? Run the numbers through our UK salary calculator before you sign. It suits fewer people near the minimum wage: pay cannot fall below the National Living Wage, £12.71 an hour for workers aged 21 and over.

What happens if you leave your job?

Leaving your job usually ends the agreement early, and you hand the car back. Some charge an early termination fee, often capped at a few monthly payments, while a few let you take over the lease yourself. Terms vary, so read the leaver clause and ask about resignation, redundancy and retirement before you sign. Long-term sickness and maternity leave can affect it too.

Pension, mortgage and other side effects

A lower gross salary shrinks anything worked out as a percentage of pay. If your pension is based on reduced salary, both contributions fall, though many employers use your notional salary, the pay before the sacrifice, instead. Ask in writing which figure they use. Lenders also look at gross salary, so a lower figure can cut what you can borrow, and statutory pay such as maternity pay can fall too.

How to decide

Start with the true monthly cost, not the headline sacrifice: tax and National Insurance saved, minus benefit-in-kind tax, compared with a personal lease or buying outright, including insurance and servicing. Then check the leaver terms, the pension basis and car availability. If the scheme does not suit you, our guide explains how to save for a car without stretching your budget.

Frequently asked questions

How much can I save with a salary sacrifice car?

It depends on your salary, your tax band and the car you choose. In the worked example in this article, a basic-rate taxpayer on a 40,000 pound salary sacrificing 400 pounds a month for an electric car saves about 94.50 pounds a month after benefit-in-kind tax, so the true cost is about 305.50 pounds a month. Higher-rate taxpayers usually save more, while a petrol or diesel car often saves very little.

Is a salary sacrifice car worth it for an electric car?

Usually yes, because the benefit-in-kind rate for a fully electric car is only 3% of its list price in 2025/26, rising to 4% in 2026/27. That low rate keeps the tax on the car far below the Income Tax and National Insurance you save on the sacrificed salary. For a petrol or diesel car the benefit-in-kind rate can reach 37%, which often wipes out the saving entirely.

What happens to my salary sacrifice car if I leave my job?

Leaving your job usually ends the agreement early and you will normally have to hand the car back. Some schemes charge an early termination fee, often capped at a set number of monthly payments, while others may let you take over the lease yourself. The terms vary by provider, so read the leaver clause and ask about resignation, redundancy and retirement before you sign.

Does a salary sacrifice car affect my pension?

It can. If your pension contribution is worked out as a percentage of your reduced salary, both your contribution and your employer's contribution will fall. Many employers avoid this by basing pension contributions on your notional salary, which is your pay before the sacrifice, but not all do. Ask your employer in writing which figure they use.

Does a salary sacrifice car affect my mortgage?

It can reduce the amount you can borrow, because lenders look at your gross salary and the sacrifice lowers your contractual pay. Most lenders are familiar with these schemes and some will add the sacrifice back when they assess affordability, but not all do. If you plan to apply for a mortgage during the term, speak to your lender or broker first.
