Electric car salary sacrifice explained: how it works and is it worth it?
With salary sacrifice you give up part of your gross pay in return for a car. Because that pay is never taxed, a £640-a-month car costs a higher-rate taxpayer about £424 a month, and a basic-rate taxpayer about £487.
How it works
- Your employer leases the car and agrees a monthly amount with you, usually covering the car, insurance, servicing and breakdown cover.
- That amount comes off your salary before income tax and National Insurance, so you save both.
- Because the car is provided through work, you pay company-car tax on it. For electric cars this is only 4% of the P11D value in 2026/27.
A worked example
A Toyota bZ4X (P11D £39,930) on a package of £640 a month, 2026/27 rates, England, Wales and Northern Ireland:
| Your band | Gross pay given up | Tax and NI saved | Company-car tax | Real cost a month | Saving |
|---|---|---|---|---|---|
| Basic rate | £640 | £179 | £27 | £487 | 24% |
| Higher rate | £640 | £269 | £53 | £424 | 34% |
| £100k–£125k (allowance taper) | £640 | £397 | £80 | £323 | 50% |
| Additional rate | £640 | £301 | £60 | £399 | 38% |
The real cost is the gross amount, less the income tax and National Insurance you no longer pay, plus the company-car tax. Packages vary by provider, so use a real quote: our ways-to-pay calculator lets you type one in.
Is it worth it?
- Usually yes for higher earners. At 40% tax and 2% National Insurance, every £100 given up costs you about £58 before company-car tax.
- Closer for basic-rate taxpayers. You still save 28p in every pound, but compare the real cost with a personal lease on a similar car.
- Strongest between £100,000 and £125,140, where sacrifice can also win back some of your personal allowance.
Check before you sign
- Your pay after the sacrifice must stay above the National Minimum Wage.
- A lower salary can affect things worked out from it, such as some pension contributions, life cover, mortgage applications and statutory pay.
- What happens if you leave, go on long-term leave or want to end early.
- What is included: insurance, servicing, tyres, breakdown cover and a home charger.
These figures are illustrations, not advice. Your employer's scheme, your exact salary and the car you choose change the result.
Common questions
How does electric car salary sacrifice save money?
You give up part of your gross salary before income tax and National Insurance are taken, and the car is provided in return. You then pay company-car tax on the car, which is low for electric cars.
How much can I save with salary sacrifice?
On our example (£640 a month gross for a Toyota bZ4X), a basic-rate taxpayer pays about £487 a month after tax and a higher-rate taxpayer about £424, saving roughly 24% and 34%.
Who benefits most from salary sacrifice?
Higher earners save the most, because each pound of salary they give up would have been taxed at a higher rate. People earning between £100,000 and £125,140 save the most of all.
What happens if I leave my job?
Schemes differ. Many include cover so you can hand the car back, but some charge an early-termination fee. Check before you sign.
Can salary sacrifice take my pay below the minimum wage?
No. Your pay after the sacrifice must stay at or above the National Minimum Wage, so schemes check this before you join.
