How salary sacrifice electric car schemes work in 2026-27, what you actually save, and how to calculate your real monthly cost.
Three things combine to make EV salary sacrifice exceptionally tax-efficient in 2026-27. First, the 3% BiK rate means the taxable benefit is tiny. Second, you sacrifice gross salary saving income tax and NI. Third, there is no fuel benefit charge for electric vehicles. For a higher rate taxpayer this can make a 600/month EV cost only 280/month in actual take-home reduction.
| Item | Without EV Sacrifice | With EV Sacrifice |
|---|---|---|
| Gross salary | 45,000 | 40,200 (sacrificed 4,800) |
| Monthly take-home | 2,843 | 2,467 |
| Monthly EV cost | 0 (not leasing) | 0 (covered by sacrifice) |
| Real reduction in take-home | none | 376 — 28% less than lease cost |
Because your employer is providing a car, HMRC charges a small Benefit in Kind tax. At 3% of the car's list price for an EV, this is minimal. On a 35,000 EV the annual BiK value is 1,050. A basic rate taxpayer pays 20% on that — just 210 per year or 17.50 per month. Vastly lower than petrol or diesel cars which have BiK rates of 25 to 37%.
Step 1: Take the monthly lease cost. Step 2: Multiply by 0.72 (basic rate) or 0.58 (higher rate) to get your take-home reduction. Step 3: Add the monthly BiK tax (car list price times 3% divided by 12 times your marginal rate). Step 4: Compare to the cost of owning, insuring and fuelling an equivalent petrol car. Most people find the EV is significantly cheaper in total.
For new EVs this almost always favours salary sacrifice provided your employer offers a scheme. The combination of tax efficiency, included insurance, maintenance and servicing in most schemes, and driving a new car every 2 to 3 years makes it highly competitive. The key risk is staying with the employer for the lease term as leaving early can trigger penalties.
How does electric car salary sacrifice work?
Your employer leases an EV and you give up gross salary to cover the lease cost. You save income tax and NI on the sacrificed amount. For a basic rate taxpayer this is a 28% saving; for higher rate taxpayers it is a 48% saving including NI.
What is the Benefit in Kind rate for electric cars in 2026-27?
The Benefit in Kind (BiK) rate for fully electric cars is 3% in 2026-27, rising to 4% in 2027-28. This extremely low rate is what makes EV salary sacrifice so financially attractive compared to petrol or diesel cars (25 to 37% BiK).
Is salary sacrifice an electric car worth it in 2026?
Yes for most people. The combination of the low 3% BiK rate, income tax and NI savings on the sacrificed salary, and exemption from fuel benefit charge creates a genuinely tax-efficient way to drive a new EV.
