For the 2026/27 UK tax year, an employer provides an employee with a company car available for the employee's private use. Under HMRC's company car benefit-in-kind rules, how is the taxable value of this benefit calculated?
- The taxable value is a fixed flat amount set annually by HMRC, the same for every company car regardless of its price or emissions
- The taxable value equals the car's full list price (P11D value), taxed in full as employment income with no percentage reduction applied
- The taxable value is the car's P11D value multiplied by an 'appropriate percentage' that HMRC sets according to the car's CO2 emissions (and, for the lowest-emission cars, its electric-only driving range), so lower-emission and electric cars attract a lower percentage and therefore a lower taxable benefit
- The taxable value is based solely on the number of business miles the employee drives in the car during the year, with private use having no bearing on the calculation
Why C? And why not the others?
Correct answer: C. The taxable value is the car's P11D value multiplied by an 'appropriate percentage' that HMRC sets according to the car's CO2 emissions (and, for the lowest-emission cars, its electric-only driving range), so lower-emission and electric cars attract a lower percentage and therefore a lower taxable benefit
HMRC values a company car benefit by multiplying the car's P11D value (broadly its list price plus most accessories) by an 'appropriate percentage' that is set according to the car's CO2 emissions, with fully electric and very low-emission cars using their electric-only range to place them in the lowest percentage bands, so a lower-emission or electric car produces a smaller taxable benefit even on an identical list price, matching the correct option. The option describing a fixed flat amount for every car is wrong because the appropriate percentage varies specifically to reflect each car's emissions profile, producing different taxable values for different cars. The option taxing the full P11D value with no percentage reduction is wrong because the percentage step is exactly what scales the P11D value down to the actual chargeable benefit; without it, every company car would be taxed identically regardless of emissions. The option basing the value solely on business mileage is wrong because the benefit-in-kind charge is for the availability of private use, not a mileage-based calculation, and business mileage does not itself determine the taxable amount.
