EV Salary Sacrifice vs Private Lease (2026/27)
An EV through salary sacrifice can be cheaper than a private lease, but it is not a simple like-for-like swap because your payslip changes and company-car tax still applies.
Quick answer
Compare the reduction in spendable income after salary sacrifice and company-car tax with the full private-lease cost. In the illustrative £40,000 salary example below, £500 a month gross sacrifice costs about £383.33 a month after tax and NI, including car tax on a £35,000 P11D value. A private lease can be cheaper if its matching total cost is lower.

Worked example: £500 salary sacrifice versus a £400 private lease
This is an illustration, not a vehicle quote. Assume £40,000 salary in England, Wales or Northern Ireland throughout 2026/27, the standard Personal Allowance, NI category A, and no pension, student loans or other benefits. The zero-emission car is available for the full tax year, has a £35,000 P11D value, and costs £500 a month in gross salary sacrifice. There are no separate employee payments towards private use.
The 2026/27 zero-emission company-car percentage is 4%. The taxable benefit is £35,000 × 4% = £1,400. At 20% Income Tax, the car tax is £280 a year. This uses the car’s P11D value, not the lease payments.
| Item | Annual amount |
|---|---|
| Gross salary given up | £6,000 |
| Less Income Tax saved on that salary | −£1,200 |
| Less employee NI saved | −£480 |
| Add company-car Income Tax | +£280 |
| Total reduction in spendable income | £4,600 (£383.33/month) |
Suppose the private lease costs £400 a month including VAT, with no initial rental or extra fees, and both packages cover the same car, mileage, insurance and maintenance. That costs £4,800 a year from take-home pay. Salary sacrifice is £200 a year (about £16.67 a month) cheaper in this illustration. A matching private package at £300 a month would instead be £1,000 a year cheaper than this salary-sacrifice example.
The £383.33 is an annual equivalent, not a promise about each payslip. Charging costs are excluded from both sides. Do not project one year’s company-car tax unchanged across a multi-year lease: rates, pay and the time the car is available can change.
To compare real quotes, add the initial rental, all later rentals, fees and any missing insurance, servicing or tyres, then divide by the contract’s months. For example, £1,200 initially plus 35 payments of £400 is £15,200 over 36 months, or £422.22 a month before other costs. Do not count the initial payment twice.
Ask your employer for the P11D value, gross sacrifice, included services and early-leaver terms. Check the vehicle-specific benefit with HMRC’s company-car guidance and calculator. Our main calculator accepts the P11D value and gross sacrifice to estimate the current-year tax cost. Compare insurance, servicing, fees and the private-lease quote separately.
What changes with a private lease
A private lease is usually just a personal bill. Your gross pay, tax code, and payroll deductions normally stay the same because the lease sits outside payroll.
That keeps the payslip simpler, but it also means you are paying the lease from money that has already been through tax and National Insurance.
What changes with EV salary sacrifice
With salary sacrifice, your employer leases the car and your contractual cash pay is reduced. That can cut the PAYE and NI charged on your cash salary before you are paid.
However, GOV.UK says company cars used privately are still taxable benefits. So the arrangement is not tax free just because the salary went down.
Why the EV benefit-in-kind charge still matters
The company-car tax charge is based on the value of the car and the relevant company-car percentage, not on your monthly lease payment. HMRC has already set the appropriate percentage path for zero-emission cars, which keeps the EV charge relatively low but not zero in 2026/27.
That is why the usual comparison is not ‘full salary sacrifice saving versus nothing’. It is ‘salary sacrifice saving minus the company-car tax charge’ versus ‘private lease from taxed income’.
Why salary sacrifice can still win on net pay
For many employees, the tax and NI saving on the sacrificed salary is larger than the EV company-car tax charge. That is the core reason EV salary sacrifice is attractive.
But the answer depends on your tax rate, the car’s value, and the scheme terms. A cheap private lease or a very expensive company-car package can narrow the gap.
Compare the payroll route with the private route
The right comparison is the net-pay effect of the work scheme against the all-in personal cost of leasing privately.
What to check before choosing
Do not compare only the monthly headline number. Check what happens with insurance, servicing, early termination, mileage limits, and what salary figure is used for pensions or borrowing checks.
If you need your reported salary to stay high for a mortgage or statutory-pay reason, the private lease may be easier even if the raw tax maths is less generous.
What to check
- A salary-sacrifice EV affects gross pay and tax.
- A private lease is usually paid from net pay outside payroll.
- A company-car tax charge can still apply to the EV through work.
What to do next
- Compare the same car and contract length before judging the cost.
- Use the worked example, your employer’s quote and HMRC’s vehicle-specific car-tax calculation.
- Check scheme paperwork for insurance, maintenance, and early-leaver terms.

Common questions
- Why do I still pay tax on an EV from work?
- Because a company car used privately is still a taxable benefit, even when salary sacrifice is used to get it.
- Does a private lease show on my payslip?
- Usually no. A private lease is normally paid from your own bank account after payroll.
- Is EV salary sacrifice always cheaper than a private lease?
- Not always. It often is, but the answer depends on the car, your tax position, and the full scheme terms.
