EV salary sacrifice lets you drive an electric car through your employer and pay significantly less than you would buying or leasing privately. The Benefit-in-Kind (BIK) rate on fully electric cars is just 3% in 2026/27 — compared with 25–37% for petrol and diesel vehicles — which makes this one of the most tax-efficient employee benefits available in the UK.
This guide explains exactly how EV salary sacrifice works, what you save, and what to watch out for.
What Is EV Salary Sacrifice?
Salary sacrifice is an arrangement where you agree to give up part of your gross salary in exchange for a non-cash benefit from your employer. With EV salary sacrifice, the employer leases an electric car and you sacrifice salary equal to the monthly lease cost.
Because the sacrifice comes from gross pay — before income tax and National Insurance (NI) — you pay no income tax or NI on the amount sacrificed. You do pay a small amount of BIK tax on the car’s value, but at 3% in 2026/27, this is minimal.
The key difference from a traditional company car: you are not receiving a car allowance or a fully employer-funded benefit. You are swapping salary for a car lease, which the employer manages on your behalf.
BIK Rates for Electric Cars 2026/27
| Vehicle type | BIK rate 2026/27 | BIK rate 2027/28 | BIK rate 2028/29 | BIK rate 2030/31 |
|---|---|---|---|---|
| Fully electric (0g/km CO2) | 3% | 4% | 5% | 7% |
| Petrol/diesel (101–125g/km) | 27% | 27% | 27% | 27% |
| Petrol/diesel (126–150g/km) | 31% | 31% | 31% | 31% |
| Petrol/diesel (151g/km+) | 37% | 37% | 37% | 37% |
Electric cars retain a significant BIK advantage through at least 2030/31. Even at 7%, the tax exposure is a fraction of a comparable petrol vehicle.
How Much Does EV Salary Sacrifice Save?
Worked Example: £35,000 Salary, £500/Month Lease
Sarah earns £35,000 a year and her employer offers an EV salary sacrifice scheme. She selects an electric car with a P11D value of £30,000 and a lease cost of £500 per month (£6,000 per year).
Salary sacrifice saving:
| Amount | |
|---|---|
| Gross salary sacrificed | £6,000/year |
| Income tax saved (20% basic rate) | £1,200/year |
| Employee NI saved (8%) | £480/year |
| Total employee saving | £1,680/year |
BIK tax payable on the car:
- P11D value: £30,000
- BIK rate: 3%
- Taxable benefit: £900
- Tax at 20%: £180/year
Net effective lease cost:
The lease costs £6,000/year gross. The employee saves £1,680 in tax and NI, then pays £180 in BIK tax. Net cost: £4,500/year (£375/month) — versus £500/month paid from net pay privately, which would actually cost the employee around £694/month gross equivalent.
Employer saving: The employer also saves 13.8% employer NI on the sacrificed £6,000 = £828/year. Many employers pass some or all of this saving back to employees, either by subsidising the lease or offering a broader car choice.
Higher Rate Taxpayer Saving
For a higher rate (40%) taxpayer on a £60,000 salary with the same £500/month lease:
- Income tax saved: £2,400/year (40%)
- Employee NI saved: £120/year (2% above the upper earnings limit)
- Total saving: £2,520/year
- BIK tax at 40%: £360/year
- Net effective cost: £3,840/year (£320/month) for the same car
The higher your marginal tax rate, the greater the saving from salary sacrifice.
How to Compare Against Private Leasing or PCP
When comparing EV salary sacrifice against a private lease or PCP deal, you must compare net costs — what you actually pay after tax:
- Private lease paid from net pay: the full amount comes out of income already taxed at 20% or 40%
- EV salary sacrifice: the lease cost comes from gross pay — you never pay tax on that income at all, only the small 3% BIK tax
For most employees, salary sacrifice is materially cheaper than the equivalent private deal, particularly for higher rate taxpayers.
Eligibility and How Schemes Work
Not every employer offers EV salary sacrifice. Here is how it typically works:
- Employer partners with a scheme provider (such as Octopus Electric Vehicles, Tusker, or LeasePlan)
- Employee selects a car from the available range on the provider’s portal
- Employer leases the car and includes it on your payroll as a salary sacrifice arrangement
- Your payslip shows reduced gross salary with a corresponding reduction in income tax and NI
- Employer reports the BIK to HMRC via P11D or payrolled benefits; you pay BIK tax via your tax code
Schemes typically run for 2–4 years. You can often include insurance, servicing, and breakdown cover in the sacrifice, making it an all-in monthly cost.
Important Caveats
Pensionable pay: If you are in a defined benefit or final salary scheme, your pension may be calculated on your reduced gross salary. This could reduce your pension entitlement. Check with your scheme before committing.
Maternity and paternity pay: Statutory Maternity Pay (SMP) is calculated on average earnings. A lower gross salary may reduce your SMP if you enter a sacrifice arrangement within the qualifying period.
Mortgage affordability: Lenders calculate affordability on gross income. Some will not add back salary sacrifice amounts, which could reduce the mortgage you can access.
National Living Wage: Your post-sacrifice salary must remain at or above the National Living Wage. Very low earners may be excluded.
Leaving early: If you leave your job before the lease ends, you may be required to pay remaining lease costs. Check the terms carefully.
EV Salary Sacrifice vs Company Car vs Car Allowance
| Option | Tax treatment | Flexibility | Works for |
|---|---|---|---|
| EV salary sacrifice | 3% BIK; sacrifice from gross | Fixed lease term | Employees wanting low net cost |
| Traditional company car | BIK on full value (3–37%) | Employer choice | Employer-funded benefit |
| Car allowance (cash) | Taxed as salary in full | Choose any car | Flexibility over tax efficiency |
For electric cars specifically, salary sacrifice is usually the most tax-efficient option available to an employee. Read our full comparison in the company car vs car allowance guide and see how company car tax (BIK) is calculated.
What You Need to Check Before Signing Up
- Does your employer run a scheme? (Ask HR)
- What cars are available and at what lease costs?
- Does the scheme include insurance, servicing, and maintenance?
- What happens if you leave before the lease ends?
- Will salary sacrifice affect your pension or mortgage?

Summary
EV salary sacrifice is one of the best employee benefits available in 2026/27. The combination of a 3% BIK rate and the income tax and NI saving on sacrificed salary can reduce the effective cost of an electric car by 28–47% compared to private financing — depending on your tax rate. The main conditions are that your employer must run a scheme, and you must check the impact on pension, maternity pay, and mortgage affordability before committing.
