How company car tax is calculated
The broad calculation is the car’s list price and taxable accessories, less an allowable employee capital contribution, multiplied by the HMRC percentage for its emissions and then adjusted for availability and required private-use payments. A fully electric car has a 4% appropriate percentage for 2026/27.
The result does not model diesel supplements, classic cars, optional remuneration arrangements, multiple cars, capital-contribution timing, fuel benefit or Scottish income-tax bands. Check HMRC’s 2026/27 company-car table.
