Do you run an electric car? Quite a lot of us do, but the answer to ‘Do you own an electric car?’ is a rather different matter. At the top of the pile of subsidies these vehicles attract is the tax benefit of an electric company car. A top-of-the-range executive petrol-powered motor attracts a benefit-in-kind tax uplift of as much as £40,000 if your grateful company pays for everything. Switch to electric, and the bill falls to £320.
