How is Company Car Tax Calculated?
Company car tax, also known as Benefit in Kind (BiK), is calculated based on the P11D value of your vehicle and its CO2 emissions. The cleaner your car, the less tax you pay. Electric vehicles (EVs) currently have a very low BiK rate of just 2%, making them the most tax-efficient option for 2024/25. Use our calculator above to estimate your monthly costs accurately.
