Is salary sacrifice worth it for an electric car?

For most higher- and basic-rate taxpayers, yes — the income tax and National Insurance you save usually outweigh the small EV Benefit-in-Kind, especially at 4% in 2026/27. Run your own numbers, as it depends on salary and car value.

How much does an EV salary-sacrifice car really cost?

Less than the headline sacrifice, because it comes out of gross pay. The real cost is the sacrifice minus the tax and NI you save, plus a small Benefit-in-Kind charge.

What is the EV Benefit-in-Kind rate for 2026/27?

4% of the car's P11D value, rising to 5% in 2027/28.

Does salary sacrifice affect my pension or mortgage?

It can — it lowers your gross salary, which can affect mortgage affordability assessments and some earnings-linked benefits. Consider this before committing.

How salary sacrifice works

When you sacrifice salary, your employer reduces your gross pay and provides a benefit instead. You save income tax and National Insurance at your marginal rate on the sacrificed amount — so the higher your tax band, the bigger the saving.

For an electric car, you then pay Benefit-in-Kind tax — but EV BIK is just 4% of the car's P11D (list) value in 2026/27, far below petrol/diesel rates. That low BIK is why EV salary sacrifice is so tax-efficient right now.

Worked example

A higher-rate taxpayer earning £60,000 sacrifices £500/month (£6,000/year) for an EV with a £40,000 P11D value:

Tax + NI saved on £6,000 at 40% + 2% = £2,520/year → net salary cost ≈ £3,480/year (~£290/month).
BIK: £40,000 × 4% = £1,600 taxable benefit × 40% = £640/year (~£53/month).
Real cost ≈ £4,120/year (~£343/month) — versus the £500/month headline.

Illustrative; your figures depend on salary, car, scheme and tax region. The calculator above computes it for your exact numbers.

Pension sacrifice

There's no Benefit-in-Kind — you simply save tax and NI on the sacrificed amount and it goes into your pension, making it one of the most efficient ways to contribute. Near £100,000 it's also a way to escape the 60% trap — see the £100k trap explained.
