Even at 5%, EVs remain dramatically cheaper than petrol alternatives from a tax perspective. Electric Car Salary Sacrifice — How It WorksYour employer leases an electric car. You sacrifice part of your salary in exchange for use of the car. The sacrificed salary is deducted before income tax and National Insurance. You pay BiK tax (3% of list price) at your marginal tax rate. Example: £40,000 EV, employee sacrifices £500/month gross (£6,000/year). Tax and NI saving: 42% (40% IT + 2% NI) × £6,000 = £2,520. BiK tax cost: 40% × (3% × £40,000) = 40% × £1,200 = £480. Net saving vs personal lease: £2,520 − £480 = £2,040/year. Net monthly cost: approximately £330 vs £500 gross.
