Understanding Salary Sacrifice for a Car in 2026/27

Salary sacrifice is an arrangement where you give up part of your contractual salary in exchange for a non-cash benefit – in this case, a car lease. The sacrificed amount comes out of your gross pay before income tax and National Insurance are calculated, reducing your tax bill and your employer’s NI. But the taxman doesn’t ignore the car entirely: you pay Benefit-in-Kind (BIK) tax on the private use of the vehicle. This guide explains how does salary sacrifice work for a car in the 2026/27 tax year, with a focus on hourly and annual pay conversions so you can see the real impact on your take-home pay.

The Basics: Hourly Rate, Annual Salary and the NLW Floor

Before you sign up, you need to know your current hourly rate and annual salary. The standard conversion used across UK pay calculations is:

Annual salary ≈ hourly rate × contracted hours per week × 52 weeks

For a typical full-time role of 37.5 hours per week, an hourly rate of £15 gives an annual salary of about £29,250. If you sacrifice £3,000 per year for a car, your post-sacrifice gross pay becomes £26,250, which works out to roughly £13.46 per hour – still above the National Living Wage (NLW) of £12.71 per hour for workers aged 21+ from April 2026.

But if you are already on the NLW floor – say £12.71 per hour on a 37.5-hour week, giving an annual salary of about £24,785 – you cannot sacrifice anything because your cash pay would drop below the legal minimum. Employers are required to block any sacrifice that would breach the NMW. This is a hard limit, not a guideline. Always check your hourly rate after the proposed sacrifice using our Hourly to Salary calculator.

How Does Salary Sacrifice Work for a Car? Step by Step

1. You agree a gross lease cost – typically including insurance, maintenance and breakdown cover. For a mid-range electric car, this might be £500–£700 per month.
2. Your employer deducts this from your gross pay before calculating income tax and employee NI. This reduces your taxable income.
3. You pay BIK tax on the car’s list price multiplied by the appropriate percentage. For a zero-emission car in 2026/27, that percentage is 4% – confirmed in the November 2025 Autumn Budget. It will rise to 5% in 2027/28, 7% in 2028/29 and 9% in 2029/30.
4. Your employer saves 15% NI on the sacrificed amount. Many employers pass on some or all of this saving to reduce your lease cost.

Example: £45,000 Electric Car in 2026/27

• BIK charge: £45,000 × 4% = £1,800 per year
• Tax at basic rate (20%): £360 per year
• Tax at higher rate (40%): £720 per year

Compare that to a petrol car with a BIK rate of 30%: the charge would be £13,500 per year, with tax of £2,700 (20%) or £5,400 (40%). The EV saves you over £2,000 a year in tax alone.

Net Monthly Cost for a Higher-Rate Taxpayer

Suppose you sacrifice £600 per month gross for an EV lease. You are a higher-rate taxpayer (40% income tax, 2% employee NI above £50,270).

• Income tax saved: £600 × 40% = £240
• Employee NI saved: £600 × 2% = £12
• Net cost before BIK: £600 – £240 – £12 = £348 per month
• Plus BIK tax: £720 per year = £60 per month
• Total net cost: £408 per month

Your employer saves £600 × 15% = £90 per month in NI, which may be used to subsidise the scheme or reduce your lease payment.

Important Considerations

Pension impact: Salary sacrifice reduces your pensionable pay. If you are in a defined-benefit scheme like the NHS Pension, each £1,000 sacrificed gives up about £18.52 of annual pension for life (1/54th). Over a three-year lease, that adds up. For state pension, your earnings must stay above the Lower Earnings Limit (£6,708 per year in 2026/27) to build a qualifying year.

NI cap on pension sacrifice from 2029: The Budget 2025 announced that from April 2029, the NI exemption on salary-sacrificed pension contributions will be capped at £2,000 per year per employee. This does not affect car or bike schemes.

Part-time workers: If you work fewer than 37.5 hours per week, your annual salary is lower, and the NLW floor bites sooner. Always convert your hourly rate to annual using your actual contracted hours. For example, a part-time worker on 20 hours per week at £15 per hour earns £15,600 per year. A £2,000 sacrifice leaves £13,600, which is £13.08 per hour – still above NLW, but with less headroom.

Should You Choose Salary Sacrifice for a Car?

For employees who need a car, EV salary sacrifice remains one of the most tax-efficient benefits available in 2026/27. The combination of low BIK rates, income tax and NI savings, and potential employer NI pass-through makes it cheaper than a personal lease in many cases. However, you must weigh the reduction in pensionable pay and the risk of falling below the NMW floor.
