PHEV company car tax on £50,000 salary — explained
With a £50,000 PHEV on a £50,000 salary, HMRC applies the 12% BIK rate to calculate a benefit in kind value of £6,000 per year. This amount is added to your gross salary, bringing your total taxable income to £56,000.
The additional Income Tax on this BIK is £2,346 per year (£207/month equivalent). You also pay National Insurance of £137 per year on the BIK value. Combined, the company car costs you £2,483 per year in extra tax — deducted through PAYE each pay period.

The company car works out roughly £85/month cheaper than running a comparable PHEV privately, making it a net financial win. For many PHEV drivers, the decision hinges on how often you actually charge at home or at work.
