How does electric vehicle salary sacrifice save money?
EV salary sacrifice lets you give up part of your gross salary to lease a fully electric car through your employer, saving Income Tax and National Insurance on the sacrificed amount, on top of the already low company car Benefit in Kind tax rate for electric vehicles, often making it far cheaper than a personal lease.
Full answer
Electric vehicle salary sacrifice combines two separate tax advantages to make leasing an electric car through an employer scheme significantly cheaper than an equivalent personal car lease, financed from already-taxed take-home pay. First, by sacrificing part of gross salary to fund the lease payment (structured the same way as pension salary sacrifice), the employee reduces their taxable gross salary, saving Income Tax at their marginal rate (20%, 40% or 45%) and employee National Insurance (8% or 2%) on the sacrificed amount, since the payment comes out of pre-tax salary rather than post-tax income. Second, the employee is then taxed on the electric car itself as a company car Benefit in Kind, but because fully electric cars currently attract one of the lowest company car tax percentages available (a policy deliberately designed to encourage electric vehicle adoption, though the rate is scheduled to increase gradually over the next few years), this second tax charge is typically very small compared with the salary sacrifice saving achieved in the first step. Combined, these two effects mean a higher-rate taxpayer can often end up paying considerably less overall each month for an electric car through a salary sacrifice scheme than they would for the same car through a standard personal lease agreement, even though the employer bears the cost of arranging the lease and typically the insurance, maintenance and breakdown cover are bundled into the single monthly sacrifice amount too, simplifying overall motoring costs into one predictable deduction. As with pension salary sacrifice and Cycle to Work schemes, reducing official contractual gross salary through EV salary sacrifice could have a small knock-on effect on mortgage affordability assessments or salary-linked benefits, so anyone planning a significant salary sacrifice arrangement alongside an imminent mortgage application should discuss the timing with a mortgage broker first.
