Who each option suits
Salary sacrifice
Best forEmployees who would otherwise lease or buy a car themselves, especially higher-rate taxpayers choosing an electric car.
Company car
Best forEmployees offered a car as part of their package, who then pay only the company car tax.
Key takeaways
- Both are taxed as company cars; the difference is who pays for the car.
- Salary sacrifice is best compared with leasing a car yourself, not with a free company car.
- Above 75 g/km, salary sacrifice loses most of its tax advantage.
- Employers pay 15% Class 1A National Insurance on company car benefits either way.
What each costs you: a worked example
A fully electric car with a £40,000 list price, for an employee in England earning £60,000, using 2026/27 rates:
- Company car: the benefit is £40,000 × 4% = £1,600, taxed at 40% = £640 a year.
- Salary sacrifice at £500 a month: you give up £6,000, save £2,400 income tax and £120 National Insurance, and pay £640 company car tax. Your take-home pay falls by £4,120 a year.
The company car is cheaper for you because your employer pays for it. That is why the useful comparison for salary sacrifice is usually with leasing a car yourself: against a £500-a-month personal lease paid from take-home pay, the same salary sacrifice saves £1,880 a year.
If you are offered a car or a cash allowance
Some employers offer a cash car allowance instead of a company car. A cash allowance is taxed and subject to National Insurance as pay, and you then fund your own car. Compare the allowance after tax and National Insurance with the company car tax, and include the cost of the car you would run with the allowance.
