Electric car salary sacrifice: how it works, what you save and the catches

Electric Car Salary Sacrifice Explained (2026/27) | Rooster

A salary sacrifice scheme lets you lease a new electric car through your employer and pay for it out of your gross salary, before income tax and National Insurance. Because EVs have a very low company car tax rate, the total cost is often far lower than leasing the same car privately. Scheme providers say employees typically save 20 to 50%.

This guide explains how salary sacrifice works, shows a worked example, and sets out the catches to check before you sign.

Last updated 27 October 2026. Tax rates are the published rates for 2026/27 onwards. The Autumn Budget on 28 October 2026 could bring changes.

Key takeaways

You give up part of your gross salary in exchange for the use of a car, usually including insurance and maintenance.
You save income tax and National Insurance on the amount sacrificed.
You pay benefit-in-kind (BiK) tax on the car, which for EVs is 4% of the list price in 2026/27.
EV BiK rates are set to rise to 5% in 2027/28, 7% in 2028/29 and 9% in 2029/30.
Your pay after the sacrifice must not fall below the National Minimum Wage.
Leaving your job early can trigger early termination charges, and a lower salary can affect pensions, mortgages and some benefits.

How does salary sacrifice work?

Your employer partners with a scheme provider and offers cars to staff.
You choose a car and sign a lease agreement, usually for two to four years.
Your gross salary is reduced by the monthly cost. Because this happens before tax and National Insurance, you pay less of both.
Because the car is a taxable benefit, you pay benefit-in-kind tax on a percentage of its list price.

Most schemes bundle in insurance, servicing, maintenance, tyres and breakdown cover, and some include a home charger. Your employer also saves employer’s National Insurance on the amount you sacrifice.

How much is the benefit-in-kind tax?

BiK tax is based on the car’s list price (its P11D value), the BiK percentage for its emissions, and your income tax rate. EVs have the lowest percentages by far.

Tax year	EV BiK rate	Typical petrol car
2026/27	4%	Around 25% to 37%
2027/28	5%	Rising
2028/29	7%	Rising
2029/30	9%	Rising

Plug-in hybrids with emissions of 1 to 50g/km move to 18% in 2028/29 and 19% in 2029/30, regardless of their electric range.

For a £40,000 EV in 2026/27, the BiK tax is £40,000 × 4% × your tax rate: £320 a year for a basic-rate taxpayer and £640 for a higher-rate taxpayer.

A worked example

This is an illustration only. Say the car’s monthly cost through the scheme is £500 and its list price is £40,000.

	Basic-rate taxpayer	Higher-rate taxpayer
Gross salary sacrificed each month	£500	£500
Income tax and NI saved	£140 (20% + 8%)	£210 (40% + 2%)
Net reduction in take-home pay	£360	£290
BiK tax each month (4% of £40,000)	About £27	About £53
Real monthly cost	About £387	About £343

Compare that with the cost of leasing the same car privately, plus insurance, servicing and breakdown cover, to see the real saving.

The catches to check

Leaving your job. If you leave, are made redundant or go on long-term leave, the lease may end early and you could face early termination charges. Many schemes include some protection, but check exactly what is covered.

Minimum wage. Your pay after the sacrifice must not fall below the National Minimum Wage, which is £12.71 an hour for workers aged 21 and over in 2026/27. This can rule out lower earners.

Pension contributions. If your pension contributions are a percentage of your salary after sacrifice, they may fall. Check whether your employer bases contributions on your pre-sacrifice salary.

Mortgages and loans. Some lenders look at your reduced salary when deciding how much to lend.

Other salary-linked benefits. Statutory maternity pay, life cover multiples and some benefits can be based on your reduced salary.

You don’t own the car. At the end of the agreement you hand it back. Check the mileage allowance and the condition rules to avoid charges.

Tax rates rise. BiK on EVs increases each year to 9% in 2029/30, so a long agreement costs more in tax in its later years.

Is salary sacrifice worth it?

For many employees who want a new EV and expect to stay with their employer for the length of the agreement, it is one of the cheapest ways to drive one. It is less attractive if your job is uncertain, you are close to the minimum wage threshold, you are about to apply for a mortgage, or you would rather own a car outright.

If you would rather buy, a used EV can also be very good value. See should you buy a used electric car? and our guide to car finance options.
