Electric vehicle (EV) salary sacrifice is one of the most tax-efficient ways to drive a new car in the UK right now. With a Benefit in Kind (BiK) rate of just 2% until 2027/28, the combination of tax and NI savings makes it significantly cheaper than a personal lease or finance deal.

How EV salary sacrifice works
Your employer leases an electric car and makes it available to you. You give up part of your gross salary in exchange — the sacrifice reduces your taxable pay. However, unlike Cycle to Work, an EV is a taxable benefit, so you pay Benefit in Kind (BiK) tax on it.
The key is that the BiK rate for fully electric cars is just 2% of the car's list price — far lower than petrol or diesel cars (which attract 25–37% BiK).
The 2% BiK rate is confirmed until 2027/28, rising to 3% in 2028/29 and 4% in 2029/30. Acting now locks in the lowest rates.
The maths: a real example
A basic rate taxpayer sacrificing £500/month for a £35,000 EV:
| Annual salary sacrifice | £6,000 |
| Income tax saved (20%) | £1,200 |
| NI saved (8%) | £480 |
| BiK tax (2% of £35,000 × 20%) | −£140 |
| Net annual saving | £1,540 |
| Monthly net saving | £128/month |
So the £500/month sacrifice effectively costs only £372/month in reduced take-home pay — and that includes insurance, servicing, and breakdown cover in most schemes.
Savings by tax band
| Tax band | Tax saved | NI saved | BiK cost | Net saving (£35k car) |
|---|---|---|---|---|
| Basic rate (20%) | £1,200 | £480 | £140 | £1,540/year |
| Higher rate (40%) | £2,400 | £120 | £280 | £2,240/year |
| 60% trap | £3,600 | £120 | £280 | £3,440/year |
Higher rate taxpayers save even more because the BiK is also taxed at their marginal rate — but the sacrifice saving is proportionally larger, so the net benefit is still strongly positive.
How BiK is calculated
BiK tax = List price × BiK % × your marginal tax rate
For a £35,000 EV at 2% BiK, taxed at 20%: £35,000 × 2% × 20% = £140/year
This is added to your Adjusted Net Income — so it slightly increases your taxable income, but the sacrifice saving far outweighs it.
What's included in most EV salary sacrifice schemes?
Most employer schemes bundle:
- The car lease
- Insurance
- Servicing and maintenance
- Breakdown cover
- Road tax (VED — currently £0 for EVs, rising to £190 from April 2025)
- Tyre replacement
Charging costs are typically not included, though some employers offer a home charger installation allowance.

Important considerations
EV salary sacrifice reduces your gross pay, which can affect mortgage affordability assessments, statutory maternity/paternity pay calculations, and pension contributions (if based on gross salary). Check these implications before signing up.
- Minimum salary: You cannot sacrifice below the National Living Wage (£11.44/hour in 2024/25)
- Contract length: Typically 2–3 years — early termination can be costly
- Employer must offer it: Not all employers run EV schemes; check with HR
How to get started
- Check your employer offers an EV salary sacrifice scheme
- Choose a car within your employer's approved list
- Get a quote — the scheme provider will show your net monthly cost
- Sign the salary sacrifice agreement
- Take delivery — payments start on your next payslip
What this means for you
On a £50,000 salary, leasing a £35,000 EV at £500/month via salary sacrifice costs you around £372/month in take-home pay — not £500. The £128/month saving covers insurance and servicing included in most schemes.
At £60,000, the saving is larger: 40% tax plus 2% NI on the sacrifice, minus the small BiK charge, leaves a net annual saving of around £2,240 on a £35,000 car.
If you are in the £100k–£125k taper zone, the effective saving rate on the sacrifice reaches 62% — making EV salary sacrifice one of the most efficient ways to reduce your tax bill while getting a new car.

FAQ
Does EV salary sacrifice affect my mortgage application?
Potentially. It reduces your gross pay, which some lenders use for affordability. Check with your mortgage adviser before signing a scheme agreement.
What happens if I leave my job mid-lease?
You may be liable for the remaining lease payments. Most schemes have early termination clauses — check the agreement carefully before signing.
Can I charge the car at work tax-free?
Yes. Employer-provided workplace charging is exempt from Benefit in Kind tax. Home charging is not covered by the scheme but some employers offer a home charger installation allowance.
Is the 2% BiK rate guaranteed?
The 2% rate is confirmed until 2027/28, rising to 3% in 2028/29 and 4% in 2029/30. These are legislated rates, not estimates.
Does the car have to be fully electric?
Yes for the 2% rate. Plug-in hybrids have higher BiK rates (5–14% depending on electric range) and are less tax-efficient.
