Salary Sacrifice Electric Car 2026/27

Written by James Whitfield · Updated August 2026 · Checked against 2026/27 HMRC rates.

Electric car salary sacrifice lets you drive a new EV through your employer, with the lease cost deducted from gross salary before tax. Your take-home falls, but you pay less income tax and employee NI on the sacrificed amount. You do owe Benefit in Kind (BIK) tax on the car — for zero-emission vehicles in 2026/27 that is 4% of P11D value.¹² Whether it works out cheaper than leasing privately depends on your tax rate and the P11D value of the car — see our salary sacrifice vs car loan or PCP comparison.

How EV salary sacrifice works

Your employer provides a company car on a lease. In exchange, you give up part of your gross salary — typically the monthly lease cost plus employer costs. The sacrifice reduces your contractual salary, so you pay less income tax and employee NI on that portion.

At the same time, the car is a company benefit. HMRC treats it as a Benefit in Kind and you owe income tax on the BIK value. The calculation:

• 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 sacrifice is relative to the BIK tax cost. For zero-emission cars the BIK percentage is low. That is why EVs are particularly tax-efficient through salary sacrifice.

BIK rate for zero-emission cars 2026/27

The appropriate percentage for zero-emission company cars in 2026/27 is 4%. HMRC has confirmed this for the current tax year.²

Future years are higher. The rate rises gradually:

• 2026/27: 4%
• 2027/28: 5%
• 2028/29: 7%

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 EV

A higher-rate taxpayer (earning above £50,270) sacrifices £8,400 a year — £700/month — to lease an EV with a £40,000 P11D value. The BIK is £40,000 × 4% = £1,600, taxed at 40% = £640.² Here's the real annual cost:

Lease the same car privately and you'd pay the full £8,400 from taxed income with no relief — the sacrifice route saves roughly £2,900 a year here.

Figures illustrate the mechanics; exact lease and P11D values vary. This site's calculator models income tax and NI savings — use the GOV.UK company car tax figures alongside it for the full BIK picture.

Effect on salary and other deductions

Salary sacrifice reduces your contractual salary. That 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.

None of these are reasons to avoid EV salary sacrifice. But understand them 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.
