How EV salary sacrifice saves you money

You give up part of your gross salary before tax. Because you pay no Income Tax or National Insurance on that part, a £450 car costs you £324 after those savings at the basic rate.

You then pay company car tax on the car. For an electric car that is 4% of the list price in 2026/27, which adds £28 a month here. Higher-rate taxpayers save 40% Income Tax but pay 40% on the benefit too.
