Salary Sacrifice Electric Car 2026/27
Published by the UK Money Calculators editorial team. Last updated for the 2026/27 tax year.
Electric car salary sacrifice lets you drive a new EV through your employer, with the lease cost deducted from your gross salary before tax. Your take-home pay falls, but you pay less income tax and employee National Insurance on the sacrificed amount. You do, however, owe Benefit in Kind (BIK) tax on the car — for zero-emission vehicles in 2026/27 the BIK appropriate percentage is 4%. Whether it works out cheaper than leasing privately depends on your tax rate and the P11D value of the car.
How EV salary sacrifice works
Your employer agrees to provide a company car (an EV on a lease). In exchange, you give up part of your gross salary — typically the monthly lease cost plus employer costs. Because the sacrifice reduces your contractual salary, you pay less income tax and employee NI on that portion.
At the same time, the car is a company benefit. HMRC treats this as a Benefit in Kind, and you owe income tax on the BIK value. The BIK calculation is:
- BIK value = P11D value × appropriate percentage
- BIK tax = BIK value × your marginal income tax rate
- No employee NI on BIK — it is not a cash payment
The net saving depends on how large the salary sacrifice is compared to the BIK tax cost. For lower-emission and zero-emission cars the BIK percentage is low, which is why EVs are particularly tax-efficient through salary sacrifice.
BIK rate for zero-emission cars 2026/27
The appropriate percentage for fully electric (zero-emission) company cars in 2026/27 is 4%. This rate is confirmed by HMRC for the current tax year.
Future years differ — the rate is scheduled to rise gradually:
- 2026/27: 4%
- 2027/28: 5%
- 2028/29: 7%
These rates are subject to change in future budgets. Check GOV.UK for the latest confirmed rates when comparing multi-year lease arrangements.
Worked example
Higher-rate taxpayer, £40,000 P11D value EV
Assume a higher-rate taxpayer sacrifices enough salary to cover a monthly lease on an EV with a P11D value of £40,000.
- BIK value: £40,000 × 4% = £1,600 per year
- BIK tax (higher rate, 40%): £1,600 × 40% = £640 per year (£53/month)
- If the annual lease sacrifice is £8,400: income tax saving at 40% = £3,360; employee NI saving at 2% above £50,270 (or 8% if below) varies
The BIK tax of £640 is a real cost to factor in, but for a zero-emission car at 4%, it is substantially lower than the income tax and NI savings on the salary sacrifice. Compare this with leasing the same car privately out of post-tax take-home pay — where you would pay the full lease cost from already-taxed income with no relief.

Effect on salary and other deductions
Salary sacrifice reduces your contractual salary, which can affect:
- Mortgage assessments — lenders may use your post-sacrifice salary as the income figure.
- Pension contributions — if employer or employee contributions are a percentage of salary, they may be calculated on the lower post-sacrifice figure.
- Life assurance and income protection — these may be linked to contractual salary.
- Statutory Maternity/Paternity Pay — calculated on average earnings, which salary sacrifice can reduce.
These considerations don't necessarily mean you should avoid EV salary sacrifice, but they are worth understanding before signing a scheme agreement.
Common mistakes
- Assuming the EV is tax-free. BIK tax still applies — it is just very low at 4% for zero-emission cars.
- Using the wrong BIK rate. The 2026/27 zero-emission rate is 4%, not 3%. Future years are higher.
- Ignoring the impact on borrowing. A lower contractual salary can reduce mortgage eligibility.
- Not checking National Minimum Wage. The sacrifice must not take your cash pay below NMW — see the minimum wage guide.

Frequently asked questions
Does salary sacrifice mean the EV is tax-free?
No. You still owe Benefit in Kind tax on the car. However, at 4% in 2026/27, the BIK tax on zero-emission cars is very low relative to the income tax and NI savings from the salary sacrifice. For many employees this still results in a net saving compared to leasing privately.
What is the BIK rate for zero-emission cars in 2026/27?
The appropriate percentage for fully electric (zero-emission) company cars for 2026/27 is 4%. This is the figure you multiply by the car's P11D value to arrive at the taxable BIK amount. The rate rises to 5% in 2027/28 and 7% in 2028/29.
Does salary sacrifice for an EV affect my pension contributions?
Potentially, yes. If your pension contributions are a percentage of salary, and your contractual salary falls due to salary sacrifice, both employee and employer contributions may be calculated on a lower base. Check your pension scheme rules.
Can I charge the car at home and claim the cost back?
If your employer reimburses home charging costs for a company EV, there are specific HMRC rules on what can be paid without triggering additional tax. Check with your employer and HMRC guidance for current approved rates.
What if I leave my job mid-lease?
This is a key risk with EV salary sacrifice. You may be liable for the remaining lease costs, or your employer may hold you to a notice period that covers the residual liability. Always read the early termination clauses in your scheme agreement before signing.
